All questions

Question 1

Which information is most critical for the nurse to verify during this process?

The date the blood was donated by the donor.
The name of the primary health care provider who ordered the blood.
The client's name, identification number, and blood type compatibility. (correct answer)
The location where the blood was collected and processed.

Explanation: Verification of the correct client identity and ABO/Rh blood type compatibility is the most critical safety step in the transfusion process. Administering blood to the wrong client or blood of an incompatible type is the leading cause of acute hemolytic transfusion reactions — potentially fatal events caused by antibody-mediated destruction of the transfused red blood cells. The dual verification process exists specifically to create a second human check on this information before the transfusion begins. The donation date (A) is relevant for blood bank inventory management but is not the nurse's primary verification responsibility at the bedside. The ordering provider's name (B) is on the prescription and should be confirmed, but does not prevent hemolytic reactions. The collection location (D) has no bearing on transfusion safety.

Question 2

A client has just started receiving a transfusion of PRBCs. The nurse is aware that the most life-threatening transfusion reactions typically occur early in the infusion.

For how long should the nurse remain at the bedside to monitor the client when the transfusion first begins?

The first 5 minutes of the infusion.
The first 15 minutes of the infusion. (correct answer)
Until the first 100 mL of blood has been infused.
For the entire duration of the four-hour transfusion.

Explanation: The nurse must remain at the bedside for the first 15 minutes of a blood transfusion — corresponding to approximately the first 50 mL infused at a standard initial rate — because this is the period during which severe, potentially fatal reactions such as acute hemolytic reactions are most likely to manifest. During this window, the client has the highest exposure to any incompatible blood, and early recognition is critical to minimizing harm. Five minutes (A) is insufficient to detect all early reactions. Waiting until 100 mL has infused (C) exposes the client to twice the volume of blood before the critical monitoring period concludes, significantly increasing risk if an incompatibility exists. Remaining for the entire transfusion (D) is not required for all clients and is not practical; periodic monitoring is appropriate after the initial critical period in stable clients.

Question 3

The nurse is monitoring a client who has been receiving a unit of PRBCs for 20 minutes. The client suddenly reports feeling very cold, begins shivering, and has a new headache. The nurse finds the client's temperature has increased from 98.2 F (36.8 C) to 100.4 F (38 C).

Which action should the nurse take first?

Slow the transfusion rate to 50 mL/hour and continue to monitor.
Administer the prescribed PRN dose of an antipyretic.
Stop the transfusion immediately and disconnect the blood tubing. (correct answer)
Cover the client with a warm blanket to address the shivering.

Explanation: Whenever a transfusion reaction is suspected, the nurse's first and non-negotiable action is to stop the transfusion immediately and disconnect the blood tubing from the IV catheter. The IV access is then maintained using 0.9% normal saline with entirely new tubing to prevent infusion of residual blood. This must happen before any other intervention because the reaction type cannot be definitively identified at the bedside — symptoms of a benign febrile non-hemolytic reaction and a life-threatening acute hemolytic reaction can appear similar in early stages. Stopping first and determining type afterward is the required protocol; doing the reverse risks catastrophic harm. Slowing the rate (A) is never appropriate when a reaction is suspected. Administering an antipyretic (B) treats a symptom while the causative agent continues to infuse. Applying a warm blanket (D) addresses comfort but does not stop the source of the problem.

Question 4

The nurse is reinforcing teaching with a client who is about to receive their first blood transfusion. The nurse is explaining what symptoms the client should report immediately to the staff.

Which statement by the client indicates a correct understanding of the information?

I should let you know if I feel any back pain or have trouble breathing. (correct answer)
It is normal to feel a bit of itching on my arms during the transfusion.
My blood pressure will likely increase significantly while the blood is going in.
I should expect to feel a mild burning sensation at the IV site.

Explanation: Back pain (particularly low back or flank pain) is a hallmark symptom of an acute hemolytic transfusion reaction, and shortness of breath can indicate circulatory overload, anaphylaxis, or TRALI — all of which require immediate intervention. The client correctly understands that these are critical symptoms to report. Choice B requires further teaching: pruritus (itching) during a transfusion is never 'normal' — it can be an early sign of an allergic reaction and must be reported promptly so the nurse can assess severity and determine whether to continue the transfusion. Normalizing itching teaches the client to tolerate a potentially worsening symptom without reporting it. Blood pressure does not typically increase significantly during a transfusion (C); a significant rise can indicate circulatory overload and a drop can indicate hemolytic or anaphylactic reaction. A burning sensation at the IV site (D) could indicate infiltration or phlebitis and should also be reported, not expected.

Question 5

Client: 45-year-old male, history of gastrointestinal bleeding. 0900 Situation: Admitted for a blood transfusion due to a hemoglobin of 7.0 g/dL. Baseline: BP 110/70 mmHg, HR 92 bpm, RR 18, Temp 98.6 F (37 C). 1000 Situation: Transfusion of 1 unit of PRBCs started at 50 mL/hour for the first 15 minutes. 1015 Assessment: Client reports sudden low back pain and feeling like his heart is racing. He appears restless and flushed. 1020 Vital Signs: BP 90/60 mmHg, HR 118 bpm, RR 24, Temp 100.2 F (37.9 C).

Which finding is the most significant indicator of an acute hemolytic transfusion reaction?

The increase in respiratory rate to 24 breaths/min.
The client's report of sudden low back pain. (correct answer)
The heart rate of 118 beats/min.
The temperature of 100.2 F (37.9 C).

Explanation: Sudden, severe low back or flank pain is the hallmark symptom of an acute hemolytic transfusion reaction and the most specific clinical cue that distinguishes this life-threatening emergency from other reaction types. It results from complement activation and cytokine release triggered by the destruction of incompatible red blood cells, causing inflammation and pain in the lumbar region. No other transfusion reaction type characteristically produces this symptom. Tachycardia (C) and fever (D) are present across multiple reaction types including the more benign febrile non-hemolytic reaction, making them less specific. Tachypnea (A) is a secondary compensatory response to the hemodynamic instability and is also non-specific.

Question 6

Based on the current clinical data, which nursing hypothesis is the priority?

Ineffective airway clearance related to anxiety.
Risk for injury related to incompatible blood transfusion. (correct answer)
Deficient fluid volume related to gastrointestinal bleeding.
Hyperthermia related to a standard transfusion response.

Explanation: An acute hemolytic transfusion reaction caused by incompatible blood is a medical emergency that can rapidly progress to shock, acute kidney failure, and disseminated intravascular coagulation if not immediately addressed. Risk for injury related to incompatible blood is therefore the priority hypothesis — it encompasses the most immediate, life-threatening consequence of the current situation and drives the most urgent nursing actions. Ineffective airway clearance (A) is not the primary concern in this presentation; the client's airway is not currently compromised. Deficient fluid volume from GI bleeding (C) is part of this client's history but is not the active emergency; the hemodynamic instability is being caused by the transfusion reaction, not ongoing bleeding. Hyperthermia as a standard response (D) is an inappropriate hypothesis because it minimizes a life-threatening reaction as benign.

Question 7

The nurse has stopped the transfusion. Which immediate action should the nurse include in the updated plan of care?

Slow the IV rate and wait for the back pain to subside.
Place the client in a prone position to relieve the back pain.
Administer a sedative to help with the client's restlessness.
Start a new IV infusion of 0.9% normal saline using new tubing. (correct answer)

Explanation: After stopping the transfusion, the nurse must maintain IV access with 0.9% normal saline using completely new tubing — not the existing blood administration set. This is critical for two reasons: it ensures residual blood remaining in the original tubing is not inadvertently infused into the client, and it maintains a patent IV line for the administration of emergency medications and fluids. Normal saline is the only compatible IV solution for this purpose. Slowing the rate and waiting (A) is incorrect — the transfusion has already been stopped and the plan of care must address what comes next, not reverse a completed decision. Administering a sedative (C) is inappropriate; restlessness is a symptom of hemodynamic compromise and masking it with sedation would obscure the clinical picture. The prone position (B) is contraindicated in a hemodynamically unstable client and does not address the underlying emergency.

Question 8

The nurse has notified the PHCP. While awaiting further orders, which task should the nurse perform?

Send the blood bag and the attached tubing back to the blood bank. (correct answer)
Ask the client to ambulate to see if the back pain improves.
Dispose of the blood bag in the room's biohazard container.
Increase the blood infusion rate to finish the unit quickly.

Explanation: The blood bag and all attached tubing must be preserved and returned to the blood bank intact following a suspected transfusion reaction. The blood bank will perform testing on the remaining blood product — including rechecking the crossmatch, blood type, and performing a direct antiglobulin test — to confirm whether an incompatibility occurred and identify its cause. This information is critical for patient safety, legal accountability, and blood bank quality processes. Additionally, a post-reaction urine specimen is typically collected to check for hemoglobinuria. Ambulation (B) is contraindicated for a hemodynamically unstable client. Disposing of the blood bag (C) would destroy the evidence needed for investigation and is a serious error. Increasing the infusion rate (D) is dangerous and directly contraindicated — the transfusion has been stopped due to a suspected reaction and must not be restarted without explicit PHCP orders after investigation.

Question 9

A nurse is caring for a client with heart failure who is receiving a unit of PRBCs. The nurse notes the client has developed a new cough, crackles at the lung bases, and a bounding pulse.

The nurse should recognize these findings as indicators of which complication?

Circulatory overload (TACO). (correct answer)
Acute hemolytic reaction.
Febrile non-hemolytic reaction.
Mild allergic reaction.

Explanation: Transfusion-Associated Circulatory Overload (TACO) occurs when the volume or rate of blood infusion exceeds the cardiovascular system's capacity to handle the increased preload. In a client with pre-existing heart failure and a compromised left ventricle, even a standard transfusion can precipitate acute pulmonary congestion. The triad of new cough, bibasilar crackles (from fluid accumulating in the alveoli), and a bounding pulse (from increased stroke volume and venous congestion) is the classic TACO presentation. This is the most common serious transfusion complication in elderly or cardiac-compromised clients. Acute hemolytic reaction (B) presents with flank pain, fever, and hypotension — not fluid overload signs. Febrile non-hemolytic reaction (C) presents with fever and chills without respiratory or fluid overload signs. Mild allergic reaction (D) presents with urticaria and localized pruritus.

Question 10

A nurse is monitoring a client during a blood transfusion. The client has developed a localized rash and hives on their chest but denies any shortness of breath or itching in the throat.

The nurse should recognize this as which type of reaction?

Acute hemolytic reaction.
Mild allergic reaction. (correct answer)
Febrile reaction.
Bacterial contamination.

Explanation: Localized urticaria (hives) and a rash confined to one body area, without systemic symptoms such as throat tightening, bronchospasm, hypotension, or respiratory distress, are the hallmark presentation of a mild allergic reaction to plasma proteins in the donor blood. This is an IgE-mediated hypersensitivity response. Importantly, mild allergic reactions are the one category of transfusion reaction where some protocols permit the transfusion to be temporarily stopped, an antihistamine administered, and the transfusion cautiously restarted if symptoms fully resolve — in contrast to all other reaction types where permanent discontinuation is required. An acute hemolytic reaction (A) presents with flank pain, fever, and hemodynamic instability — not isolated skin findings. A febrile reaction (C) presents with fever and chills without urticaria. Bacterial contamination (D) causes high fever, rigors, and rapid hemodynamic collapse — not localized hives.

Question 11

The nurse is preparing to delegate tasks to a UAP for a client who is currently receiving a blood transfusion.

Which task is appropriate for the nurse to delegate to the UAP?

Monitor the client for the first 15 minutes of the transfusion.
Measure and report the client's vital signs after the first 15 minutes. (correct answer)
Verify the blood unit compatibility with the nurse at the bedside.
Adjust the IV flow rate if the client reports feeling dizzy.

Explanation: After the initial critical 15-minute monitoring period has been completed by the nurse and the client is stable, measurement and reporting of vital signs is an appropriate task to delegate to a UAP. Vital sign collection is within UAP scope; the nurse retains responsibility for interpreting the findings and determining the response. Monitoring during the first 15 minutes (A) requires nursing judgment to detect subtle early reaction signs and is not delegatable — the nurse must be present and conducting this assessment personally. Blood product verification (C) requires the dual-signature process performed by licensed personnel and cannot be delegated to a UAP. Adjusting the IV flow rate in response to a symptom (D) requires clinical judgment and assessment — this is a nursing function that cannot be delegated to a UAP.

Question 12

The nurse is assessing a client 30 minutes after a blood transfusion has been completed. The client's temperature is now 101.5 F (38.6 C), an increase of 2 F from their baseline, and they are experiencing chills.

The nurse should categorize this as which type of reaction?

Acute hemolytic.
Anaphylactic.
Circulatory overload.
Febrile non-hemolytic. (correct answer)

Explanation: A febrile non-hemolytic transfusion reaction (FNHTR) is defined by a temperature increase of at least 1 degree C (1.8 degrees F) from baseline occurring during or shortly after a transfusion, without evidence of hemolysis or other identifiable cause. This is the most common type of transfusion reaction and is caused by cytokines that accumulate in stored blood or by recipient antibodies reacting against donor leukocytes. The 2 F rise with chills in the absence of back pain, hypotension, urticaria, or respiratory distress fits this profile precisely. Acute hemolytic reaction additionally features flank pain, hemoglobinuria, and hemodynamic instability. Circulatory overload presents with respiratory symptoms and hypertension rather than fever. Anaphylactic reaction presents with urticaria, bronchospasm, and severe hypotension, and notably can occur without fever.

Question 13

A nurse is caring for a client who is receiving a unit of platelets. The nurse notes the client is suddenly experiencing severe shortness of breath and their SpO2 has dropped to 85%.

After stopping the transfusion, what is the priority nursing action?

Administer a prescribed diuretic.
Encourage the client to drink a glass of water.
Perform a focused assessment of the client's pedal pulses.
Place the client in a high-Fowler's position and provide oxygen. (correct answer)

Explanation: Severe respiratory distress with an SpO2 of 85% is immediately life-threatening. After stopping the transfusion, the priority is to support oxygenation: positioning the client upright in high-Fowler's maximizes lung expansion and reduces the work of breathing, while supplemental oxygen directly addresses the hypoxemia. This presentation — sudden severe respiratory distress during a platelet transfusion — is most consistent with Transfusion-Related Acute Lung Injury (TRALI), a non-cardiogenic pulmonary edema caused by donor antibodies activating recipient neutrophils in the pulmonary vasculature. This is a critical distinction: a diuretic (A) is the appropriate treatment for TACO (cardiogenic pulmonary edema from fluid overload), but administering a diuretic in TRALI can worsen the outcome because the problem is not excess fluid volume but increased alveolar capillary permeability. Without additional data, high-Fowler's and oxygen are the appropriate immediate actions for any acute respiratory emergency. Assessing pedal pulses (C) is not the priority in a respiratory emergency. Encouraging fluids orally (B) is inappropriate and potentially dangerous.

Question 14

The nurse has completed a blood transfusion and is documenting the event in the client's medical record.

Which information must the nurse include in the documentation?

The type of IV catheter used for the infusion.
The name of the technician who delivered the blood.
The unit number, start and end times, and the client's response. (correct answer)
The temperature of the room during the transfusion.

Explanation: Accurate and complete documentation of a blood transfusion is both a legal requirement and a professional accountability standard. Required elements include: the blood product type and unit identification number (for traceability and reaction investigation), the start and end times (for 4-hour time limit compliance and timing of any reaction), and the client's response throughout and after the transfusion (including vital signs at intervals and any adverse signs or symptoms). The type of IV catheter (A) is not a required transfusion documentation element, though IV access information may be documented elsewhere. The delivery technician's name (B) is a blood bank chain-of-custody record but is not required in the nurse's clinical documentation. Room temperature (D) has no clinical bearing on transfusion documentation.

Question 15

The nurse recognizes that the client's drop in blood pressure and increased heart rate most likely indicates:

The client is experiencing an expected response to the volume of blood.
The client is developing severe cardiovascular compromise consistent with an acute hemolytic transfusion reaction. (correct answer)
The client is experiencing a febrile non-hemolytic reaction.
The client is developing circulatory overload from the infusion rate.

Explanation: Hypotension and compensatory tachycardia in the setting of a blood transfusion, combined with the hallmark symptom of sudden low back pain and systemic signs of flushing and restlessness, indicate severe cardiovascular compromise from an acute hemolytic transfusion reaction. This is caused by complement activation and massive cytokine release triggered by antibody-mediated destruction of incompatible red blood cells — a distinct mechanism from anaphylaxis but equally life-threatening, capable of progressing to shock, disseminated intravascular coagulation, and acute kidney failure. An expected volume response (A) would increase blood pressure, not decrease it. A febrile non-hemolytic reaction (C) produces fever and chills but does not typically cause the hemodynamic instability seen here. Circulatory overload or TACO (D) presents with elevated blood pressure, pulmonary crackles, and respiratory distress — not hypotension — because it results from excessive volume, not fluid loss.

Question 16

The nurse is monitoring the client's urine output following the reaction. Which finding would indicate a successful stabilization of the client?

The urine appears dark, tea-colored, or smoky.
The client produces 30 to 50 mL of clear, yellow urine per hour. (correct answer)
The client reports that the back pain has moved to the chest.
The blood pressure remains at 90/60 mmHg for two hours.

Explanation: Adequate urine output of 30 to 50 mL per hour that is clear and yellow indicates that the kidneys are being adequately perfused and are successfully filtering — confirming that acute tubular necrosis from hemoglobin precipitation in the renal tubules has been avoided. This is the key outcome measure following a suspected hemolytic transfusion reaction. Choice A (dark, tea-colored, or smoky urine) is the opposite of a good sign — this appearance indicates hemoglobinuria, meaning free hemoglobin from destroyed red blood cells is being filtered by the kidneys and signals impending or active renal injury. Choice C (back pain moving to the chest) suggests progression or complication, not stabilization. Choice D (sustained hypotension at 90/60 mmHg for two hours) indicates the client is NOT stabilizing and remains in hemodynamic compromise.

Question 17

The nurse is observing a unit of PRBCs that was delivered from the blood bank 45 minutes ago but has not yet been hung.

Which action should the nurse take next?

Hang the blood immediately to ensure it is finished on time.
Return the blood unit to the blood bank. (correct answer)
Place the blood unit in the clinical unit's refrigerator.
Warm the blood unit in the microwave for 30 seconds.

Explanation: Blood products must be initiated within 30 minutes of leaving the blood bank's controlled refrigeration environment. At 45 minutes, this window has passed and the blood must be returned to the blood bank — it cannot be safely hung. Outside of controlled storage, the temperature of blood rises, creating conditions that promote bacterial growth and accelerate red cell breakdown, making the product both potentially contaminated and less therapeutically effective. Hanging the blood immediately (A) is unsafe because the 30-minute rule has already been violated; the product's safety can no longer be guaranteed. Placing the blood in the clinical unit's refrigerator (C) is not an acceptable solution — unit refrigerators are not regulated blood bank environments and are not approved for blood product storage. Microwaving (D) is strictly prohibited; it causes uneven heating, hemolysis, and destruction of the blood product.

Question 18

A nurse on a medical unit is preparing to monitor a client who is receiving a unit of packed red blood cells (PRBCs) for severe anemia. The unit was just delivered from the blood bank. Before the transfusion begins, the nurse must establish a baseline for comparison.

Which action should the nurse take first?

Check the client's bowel sounds and abdominal girth.
Measure and record the client's temperature, pulse, respirations, and blood pressure. (correct answer)
Ensure the client has consumed a high-protein meal.
Verify the client's current weight and height for the record.

Explanation: Establishing a complete set of baseline vital signs — temperature, pulse, respirations, and blood pressure — is the essential first action before initiating any blood transfusion. These values serve as the reference against which all subsequent measurements during the transfusion are compared; any clinically significant deviation can indicate an early transfusion reaction and must be identified promptly. Without a documented baseline, the nurse cannot determine whether a change in temperature, heart rate, or blood pressure represents a new finding or a pre-existing condition. Bowel sounds and abdominal girth (A) are not relevant pre-transfusion parameters. A pre-transfusion meal (C) is not required and has no bearing on transfusion safety. Weight and height (D) are useful clinical data but are not the pre-transfusion priority.

Question 19

A unit of PRBCs has been infusing for 3.5 hours, and there is still 100 mL left in the bag. The nurse is concerned about the risk of bacterial growth.

What is the maximum time allowed for a single unit of blood to be infused?

2 hours.
4 hours. (correct answer)
6 hours.
8 hours.

Explanation: The maximum time allowed for infusion of a single unit of blood products is 4 hours from the time the transfusion began. This limit exists because blood is a rich medium for bacterial growth; as the product warms to room temperature over time, any bacteria present can proliferate to dangerous levels. Exceeding 4 hours significantly increases the risk of transfusion-transmitted bacterial sepsis, a life-threatening complication. In this scenario, 3.5 hours have elapsed with 100 mL remaining; the nurse must determine whether the infusion can be safely completed within the remaining 30 minutes. If the current rate will not allow completion within the 4-hour window, the unit must be discontinued and the PHCP notified. A 2-hour limit (A) is not the standard but is sometimes used in immunocompromised clients. Six or eight hours (C, D) far exceed safe limits and would create unacceptable risk of septic transfusion reaction.

Question 20

The nurse is preparing to administer a unit of PRBCs. The nurse notes that the only available IV fluid hanging at the bedside is 5% Dextrose in 0.45% Sodium Chloride (D5 1/2 NS).

Which action should the nurse take regarding the IV fluids?

Replace the current fluid with a bag of 0.9% Normal Saline. (correct answer)
Use the current D5 1/2 NS to prime the blood tubing.
Mix the blood unit with the D5 1/2 NS to dilute it.
Discontinue the IV fluids entirely during the transfusion.

Explanation: Only 0.9% Normal Saline (isotonic saline) is compatible with blood products. It must be used both to prime the blood administration tubing before the transfusion and to flush the line after. Dextrose-containing solutions such as D5 1/2 NS cause red blood cell clumping and hemolysis by altering the osmotic environment around the cells, rendering the transfusion both ineffective and potentially dangerous. Calcium-containing solutions such as Lactated Ringer's are also incompatible because calcium can chelate the anticoagulant citrate in stored blood, causing clot formation in the tubing. Using D5 1/2 NS to prime the tubing (B) introduces an incompatible solution into the line before the blood even begins. Mixing the blood with D5 1/2 NS (C) would directly cause hemolysis of the product. Discontinuing IV fluids entirely (D) is unnecessary and removes the ability to deliver emergency medications or fluids if a reaction occurs.
