All questions

Question 1

A 63-year-old client with COPD is prescribed hydromorphone 0.2 mg IV push for severe post-operative pain. After administration, the client becomes difficult to arouse; RR 8/min, SpO2 86% on room air, BP 98/60. Which finding should be REPORTED immediately after medication administration?

  1. Client requests repositioning for comfort
  2. Pain decreased from 9/10 to 3/10
  3. Client reports mild itching without rash
  4. RR 8/min with decreased level of consciousness (correct answer)

Explanation: This question tests knowledge of parenteral medication administration and clinical judgment in opioid side effects. The key assessment finding after administration is RR 8/min with decreased consciousness, indicating overdose. Reporting the low RR with LOC change immediately is critical as it requires intervention like naloxone, aligning with safe practice. Pain reduction is expected; mild itching or repositioning requests are minor. The decision-making principle is rapid recognition of respiratory depression. Safety guidelines include continuous monitoring post-opioid. A transferable strategy is to have emergency protocols accessible for opioid-related events.

Question 2

A 66-year-old client is receiving gentamicin IV for a post-operative infection. Latest labs: BUN 38 mg/dL, creatinine 2.1 mg/dL (elevated from baseline 1.0); urine output 20 mL/hr. Which finding should be REPORTED immediately after medication administration?

  1. Creatinine 2.1 mg/dL with decreased urine output (correct answer)
  2. Client reports mild nausea after breakfast
  3. Temperature decreased from 101.2°F to 100.4°F (38.4°C to 38°C)
  4. IV site is intact with no redness

Explanation: This question tests knowledge of parenteral medication administration and clinical judgment in aminoglycoside monitoring. The key assessment finding after administration is elevated creatinine with low urine output, signaling nephrotoxicity. Reporting the creatinine 2.1 mg/dL with decreased output immediately is critical as gentamicin can cause renal damage, aligning with safe practice. Mild nausea or temperature decrease is less urgent; intact IV site is positive but not the issue. The decision-making principle is to monitor renal function serially. Safety guidelines include holding for rising creatinine. A transferable strategy is to trend labs and output during ototoxic/nephrotoxic therapies.

Question 3

A client with a peripheral IV infusion reports pain at the insertion site. The nurse observes that the site is pale, cool to the touch, and swollen.

Which action should the nurse take FIRST?

  1. Slow the IV infusion rate.
  2. Elevate the affected extremity.
  3. Stop the infusion and remove the catheter. (correct answer)
  4. Notify the registered nurse (RN).

Explanation: The client's signs and symptoms (pain, pallor, coolness, swelling) are classic indicators of IV infiltration, where the IV fluid is leaking into the surrounding tissue. The first and most important action is to stop the infusion immediately to prevent further fluid from entering the tissue and causing more damage. After stopping the infusion, the nurse should remove the catheter, elevate the limb, and notify the RN.

Question 4

A client received an intramuscular antibiotic 15 minutes ago and now reports feeling anxious, having difficulty breathing, and itching all over. The nurse observes facial swelling.

What is the nurse's immediate priority?

  1. Document the findings in the client's record.
  2. Administer an ordered PRN dose of diphenhydramine.
  3. Reassure the client that this is a common side effect.
  4. Call for immediate assistance and notify the RN. (correct answer)

Explanation: The client is exhibiting signs of anaphylaxis, a life-threatening allergic reaction. The LPN's immediate priority is to recognize this emergency and activate the facility's emergency response system or call for the RN and other help. This ensures the client receives rapid, advanced medical intervention. While documentation and medication administration are important, securing immediate help is the first and most critical action.

Question 5

A client is prescribed to receive 1000 mL of 0.9% sodium chloride over 8 hours. The IV tubing has a drop factor of 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many drops per minute?

  1. 15 gtt/min
  2. 21 gtt/min
  3. 31 gtt/min (correct answer)
  4. 42 gtt/min

Explanation: To calculate the flow rate in drops per minute (gtt/min), use the formula: (Total volume in mL × Drop factor) / Total time in minutes. First, convert hours to minutes: 8 hours × 60 minutes/hour = 480 minutes. Then, apply the formula: (1000 mL × 15 gtt/mL) / 480 min = 15000 / 480 = 31.25 gtt/min. The nurse should set the rate to 31 gtt/min.

Question 6

The nurse is discontinuing a peripheral intravenous catheter for a client who is not on anticoagulant therapy. What is the most important action for the nurse to take immediately after removing the catheter from the vein?

  1. Apply firm pressure to the site with a sterile gauze pad.
  2. Ask the client to bend the elbow to hold pressure.
  3. Apply a warm compress to the site.
  4. Check the catheter tip to ensure it is intact. (correct answer)

Explanation: While applying pressure is a crucial step to prevent bleeding, the most critical safety action is to inspect the removed catheter tip to verify that it is intact. A broken catheter tip can become an embolus in the bloodstream, which is a medical emergency. After confirming the catheter is intact, the nurse should apply pressure to the site.

Question 7

A client with a peripheral IV infusion reports pain at the insertion site. The nurse observes that the site is pale, cool to the touch, and swollen.

Which action should the nurse take FIRST?

  1. Slow the IV infusion rate.
  2. Elevate the affected extremity.
  3. Stop the infusion and remove the catheter. (correct answer)
  4. Notify the registered nurse (RN).

Explanation: The client's signs and symptoms (pain, pallor, coolness, swelling) are classic indicators of IV infiltration, where the IV fluid is leaking into the surrounding tissue. The first and most important action is to stop the infusion immediately to prevent further fluid from entering the tissue and causing more damage. After stopping the infusion, the nurse should remove the catheter, elevate the limb, and notify the RN.

  2. Administer an ordered PRN dose of diphenhydramine.
  3. Reassure the client that this is a common side effect.
  4. Call for immediate assistance and notify the RN. (correct answer)

Explanation: The client is exhibiting signs of anaphylaxis, a life-threatening allergic reaction. The LPN's immediate priority is to recognize this emergency and activate the facility's emergency response system or call for the RN and other help. This ensures the client receives rapid, advanced medical intervention. While documentation and medication administration are important, securing immediate help is the first and most critical action.

Question 9

The nurse is discontinuing a peripheral intravenous catheter for a client who is not on anticoagulant therapy. What is the most important action for the nurse to take immediately after removing the catheter from the vein?

  1. Apply firm pressure to the site with a sterile gauze pad.
  2. Ask the client to bend the elbow to hold pressure.
  3. Apply a warm compress to the site.
  4. Check the catheter tip to ensure it is intact. (correct answer)

Explanation: While applying pressure is a crucial step to prevent bleeding, the most critical safety action is to inspect the removed catheter tip to verify that it is intact. A broken catheter tip can become an embolus in the bloodstream, which is a medical emergency. After confirming the catheter is intact, the nurse should apply pressure to the site.

Question 10

A client is prescribed to receive 1000 mL of 0.9% sodium chloride over 8 hours. The IV tubing has a drop factor of 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many drops per minute?

  1. 15 gtt/min
  2. 21 gtt/min
  3. 31 gtt/min (correct answer)
  4. 42 gtt/min

Explanation: To calculate the flow rate in drops per minute (gtt/min), use the formula: (Total volume in mL × Drop factor) / Total time in minutes. First, convert hours to minutes: 8 hours × 60 minutes/hour = 480 minutes. Then, apply the formula: (1000 mL × 15 gtt/mL) / 480 min = 15000 / 480 = 31.25 gtt/min. The nurse should set the rate to 31 gtt/min.

Question 11

A 72-year-old post-operative client is receiving enoxaparin subcutaneous. Thirty minutes after the injection, the client reports new lower back pain and dizziness; VS: BP 88/54, HR 122, RR 22; skin cool and clammy. Which finding should be REPORTED immediately after medication administration?

  1. Small ecchymosis at the injection site
  2. BP 88/54 with dizziness and cool clammy skin (correct answer)
  3. Client reports mild burning during the injection
  4. Client requests to use an ice pack at the injection site

Explanation: This question tests knowledge of parenteral medication administration and clinical judgment in monitoring anticoagulants. The key assessment finding after administration is BP 88/54 with dizziness and cool skin, suggesting hemorrhage. Reporting the low BP with symptoms immediately is critical as it indicates bleeding complication, aligning with safe practice. Small ecchymosis or burning is common; requesting ice is minor. The decision-making principle is to detect hemodynamic instability post-dose. Safety guidelines require vital sign monitoring after enoxaparin. A transferable strategy is to assess for bleeding signs like hypotension routinely after injections.

Question 12

A 5-year-old child with type 1 diabetes received insulin lispro subcutaneous with lunch. One hour later the child becomes irritable and sleepy; capillary blood glucose is 49 mg/dL; HR 124, RR 24. Which finding should be REPORTED immediately after medication administration?

  1. Blood glucose 49 mg/dL with behavior change (correct answer)
  2. Child requests an extra snack at bedtime
  3. Small bruise noted at the injection site
  4. Child reports mild hunger before dinner

Explanation: This question tests knowledge of parenteral medication administration and clinical judgment in monitoring rapid-acting insulin. The key assessment finding after administration is blood glucose of 49 mg/dL with irritability and sleepiness, indicating hypoglycemia. Reporting the low glucose with behavior change immediately is critical as it requires urgent treatment, aligning with safe practice. Requesting a snack or mild hunger is normal; a small bruise is minor and expected. The decision-making principle is to recognize post-administration hypoglycemia symptoms promptly. Safety guidelines include glucose checks after insulin. A transferable strategy is to educate on hypoglycemia signs and monitor closely after doses.

Question 13

The nurse is preparing to administer a prescribed antibiotic via IV piggyback to a client with a stable, existing peripheral IV line. Which action is essential before starting the infusion?

  1. Flush the IV line with 10 mL of heparin.
  2. Check for compatibility between the antibiotic and the primary IV fluid. (correct answer)
  3. Ask the RN to start a new IV line for the antibiotic.
  4. Set the primary bag to a keep-vein-open (KVO) rate.

Explanation: Before administering an IV piggyback medication, it is critical to verify the compatibility of the secondary medication with the primary IV solution. If the solutions are incompatible, a precipitate could form, clogging the IV line and potentially causing an embolus. This is a crucial safety check. Flushing with heparin is not standard for peripheral IVs, and a new line is unnecessary if the current one is patent and the fluids are compatible.

Question 14

The nurse is using the Z-track method to administer an intramuscular injection of iron dextran. What is the primary purpose of this technique?

  1. To decrease the pain of the injection.
  2. To prevent medication from leaking into subcutaneous tissue. (correct answer)
  3. To ensure the medication is absorbed more rapidly.
  4. To reduce the risk of injecting into a blood vessel.

Explanation: The Z-track method involves pulling the skin and subcutaneous tissue to the side before injection, then releasing it after the needle is withdrawn. This creates a zigzag path that seals the medication deep within the muscle, preventing it from leaking back into the subcutaneous tissue and skin, which is especially important for irritating medications like iron.

Question 15

The nurse is administering a tuberculin skin test. Which action demonstrates the correct technique for an intradermal injection?

  1. Inserting the needle at a 45-degree angle.
  2. Massaging the site after injecting the medication.
  3. Administering the injection into the subcutaneous tissue.
  4. Inserting the needle with the bevel facing up. (correct answer)

Explanation: For an intradermal injection, the needle should be inserted at a 5 to 15-degree angle with the bevel facing up. This ensures the medication is injected into the dermis, forming a small, visible wheal or bleb. A 45-degree angle is for subcutaneous injections. Massaging the site can disperse the medication and interfere with test results.

Question 16

The nurse is preparing to administer a mixture of 10 units of regular insulin and 20 units of NPH insulin. Which action should the nurse perform first?

  1. Draw up the NPH insulin into the syringe.
  2. Draw up the regular insulin into the syringe.
  3. Inject 20 units of air into the NPH insulin vial. (correct answer)
  4. Inject 10 units of air into the regular insulin vial.

Explanation: When mixing insulins, the correct sequence is to inject air into the longer-acting (cloudy, NPH) vial first, then inject air into the shorter-acting (clear, regular) vial. After that, withdraw the regular insulin, and then withdraw the NPH insulin. This prevents contamination of the regular insulin with the NPH insulin. Therefore, the very first step is injecting air into the NPH vial.

Question 17

A primary health care provider has prescribed a 1.5 mL intramuscular injection. The client prefers the injection in the arm. What is the nurse's most appropriate action?

  1. Administer the full dose into the deltoid muscle.
  2. Divide the dose into two 0.75 mL injections in the same deltoid.
  3. Inform the client that the deltoid muscle is not recommended for this volume. (correct answer)
  4. Ask the client to choose between the ventrogluteal or vastus lateralis site.

Explanation: The deltoid muscle is a small muscle and should not receive more than 1 mL of medication per injection to avoid tissue damage and ensure proper absorption. The nurse's most appropriate action is to educate the client about this safety limitation and then proceed to select a larger, more appropriate site like the ventrogluteal muscle. Simply asking the client to choose without providing education is incomplete.

Question 18

The nurse is preparing to draw medication from a glass ampule. After breaking the neck of the ampule, what is the next step?

  1. Inject an equal amount of air into the ampule.
  2. Use a filter needle to withdraw the medication. (correct answer)
  3. Turn the ampule upside down and insert a regular needle.
  4. Wipe the broken top with an alcohol swab.

Explanation: When an ampule is opened, there is a risk of microscopic glass shards entering the solution. A filter needle must be used to withdraw the medication to prevent these particles from being drawn into the syringe and injected into the client. Air is not injected into an ampule, as it is an open system. Wiping the broken edge is not necessary and could introduce fibers into the medication.

Question 19

A client requests pain medication. The medication administration record (MAR) shows an order for morphine sulfate 2 mg IV push every 4 hours as needed. What is the practical nurse's priority action?

  1. Administer the medication as prescribed.
  2. Assess the client's pain level and respiratory rate.
  3. Notify the registered nurse (RN) of the client's request. (correct answer)
  4. Prepare the medication for administration by the RN.

Explanation: Administering IV push medications is generally outside the scope of practice for a Licensed Practical Nurse (LPN/VN). While assessing the client's pain is an important data collection step, the priority action related to the medication order itself is to notify the RN. The RN is responsible for assessing the client and administering the IV push medication.

Question 20

The nurse is preparing to administer a subcutaneous injection to a very thin, cachectic client. Which angle of insertion is most appropriate?

  1. 15 degrees
  2. 45 degrees (correct answer)
  3. 60 degrees
  4. 90 degrees

Explanation: For a thin or cachectic client with a limited amount of subcutaneous tissue, a 45-degree angle is used for a subcutaneous injection. This angle helps ensure the medication is delivered into the subcutaneous layer and not into the underlying muscle. A 90-degree angle is used for clients with an adequate or large amount of subcutaneous tissue. A 15-degree angle is for intradermal injections.
