Question 1

1. Administer extra glimepiride without an order because the glucose is above 300 mg/dL
2. Give orange juice to lower the glucose and prevent hypoglycemia later
3. Delay any action until the next scheduled glucose check to see if it improves
4. Notify the RN of the elevated glucose and assess for dehydration or altered mental status (correct answer)

Explanation: This question tests blood glucose monitoring and client safety in responding to hyperglycemia in a client with kidney disease. The key assessment finding is a capillary blood glucose of 332 mg/dL with fatigue and blurry vision after high-carb foods. The correct answer, notifying the RN and assessing for dehydration or altered mental status, is the best choice due to risks in renal impairment like reduced drug clearance. Giving juice treats hypoglycemia not present, extra glimepiride without order is unsafe, and delaying action risks complications. A decision-making principle in glucose monitoring is to consider comorbidities like kidney disease when evaluating elevated readings. A transferable nursing strategy for monitoring blood glucose levels is to promote balanced meals to mitigate postprandial spikes in at-risk clients.

Question 2

1. Skip handwashing if you used hand sanitizer within the last hour
2. Use a new lancet each time and dispose of it in a puncture-resistant sharps container (correct answer)
3. Dispose of lancets in the regular trash if the cap is replaced
4. Squeeze the fingertip repeatedly until a large drop forms to improve accuracy

Explanation: This question tests blood glucose monitoring and client safety with focus on infection prevention. The key client need is safe disposal and hygiene, noting oral contraceptives' glucose effects. The correct answer, using a new lancet each time and disposing in a sharps container, is the best choice to minimize infection and injury risks. Disposing in regular trash is hazardous, skipping handwashing allows errors, and excessive squeezing dilutes samples. A decision-making principle in glucose monitoring is to adhere to universal precautions for blood handling. A transferable nursing strategy for monitoring blood glucose levels is to review hormonal influences on glucose and adjust education accordingly.

Question 3

1. Rotate fingerstick sites and use the sides of the fingertip rather than the pad (correct answer)
2. Use lotion on the fingertip before lancing to reduce pain
3. Milk the finger from tip to base to increase blood flow
4. Keep test strips unsealed so they are easier to remove quickly

Explanation: This question tests blood glucose monitoring and client safety through proper technique to minimize discomfort and ensure accuracy. The key client need is safe self-testing, considering beta-blockers may mask hypoglycemia symptoms. The correct answer, rotating fingerstick sites and using the sides of the fingertip, is the best choice to reduce callus formation and nerve damage while maintaining accuracy. Using lotion before lancing can contaminate the sample, milking the finger introduces inaccuracies, and keeping strips unsealed exposes them to air degradation. A decision-making principle in glucose monitoring is to alternate sites to preserve skin integrity. A transferable nursing strategy for monitoring blood glucose levels is to monitor for atypical hypoglycemia signs in clients on masking medications like beta-blockers.

Question 4

1. Increased thirst
2. Frequent urination
3. Warm, dry skin
4. Trembling and diaphoresis (correct answer)

Explanation: This question tests blood glucose monitoring and client safety by recognizing urgent hypoglycemia symptoms in a client with type 2 diabetes. The key assessment finding is a capillary blood glucose of 58 mg/dL with sweating, trembling, and irritability after skipping a meal. The correct answer, trembling and diaphoresis, indicates the need for immediate intervention as these adrenergic symptoms signal severe hypoglycemia that can progress to neuroglycopenia. Warm, dry skin and increased thirst or urination are signs of hyperglycemia, which do not require the same urgency in this low-glucose context. A decision-making principle in glucose monitoring is to intervene immediately for glucose below 70 mg/dL with symptoms to prevent seizures or coma. A transferable nursing strategy for monitoring blood glucose levels is to teach clients about medication timing with meals to avoid hypoglycemic episodes.

Question 5

1. Client asks to have glucose checked before breakfast instead of after breakfast
2. Client requests decaffeinated coffee with dinner
3. Capillary blood glucose of 462 mg/dL with dry mouth and weakness (correct answer)
4. Client prefers to use the left hand for fingersticks

Explanation: This question tests blood glucose monitoring and client safety by prioritizing reporting of critical hyperglycemia in an elderly client. The key assessment finding is a capillary blood glucose of 462 mg/dL with dry mouth and weakness after high-sugar intake. The correct answer, reporting this elevated glucose with symptoms, is the best choice as it signals potential hyperosmolar state requiring RN intervention. Requests to change testing times, hand preferences, or decaffeinated coffee are routine and non-urgent. A decision-making principle in glucose monitoring is to report glucose over 400 mg/dL immediately, especially with dehydration signs. A transferable nursing strategy for monitoring blood glucose levels is to educate on low-glycemic alternatives to prevent spikes in vulnerable populations.

Question 6

1. Delegate the next glucose check to the UAP because insulin has been given before
2. Administer correctional insulin lispro per the ordered sliding scale and reassess the client (correct answer)
3. Give 4 ounces of juice and recheck the glucose in 15 minutes
4. Hold all insulin for the rest of the day to prevent hypoglycemia

Explanation: This question tests blood glucose monitoring and client safety in correcting hyperglycemia per protocol. The key assessment finding is a capillary blood glucose of 340 mg/dL with thirst and blurry vision after high-carb intake. The correct answer, administering correctional insulin lispro per sliding scale and reassessing, is the best choice to lower glucose safely under standing orders. Holding insulin risks worsening, giving juice is for hypoglycemia, and delegating checks is not the priority action. A decision-making principle in glucose monitoring is to follow evidence-based protocols like sliding scales for adjustments. A transferable nursing strategy for monitoring blood glucose levels is to reassess after interventions to evaluate effectiveness and prevent rebound.

Question 7

1. Share lancet devices with family members as long as the lancet is changed
2. Store test strips in the bathroom medicine cabinet to keep them convenient
3. Record the result with the date, time, and relation to meals (for example, before breakfast) (correct answer)
4. If the meter gives an unexpected result, ignore it and retest at the next scheduled time

Explanation: This question tests blood glucose monitoring and client safety for accurate record-keeping in a newly diagnosed client with type 2 diabetes. The key client need is proper documentation to track patterns, especially with hydrochlorothiazide's potential to raise glucose. The correct answer, recording the result with date, time, and relation to meals, is the best choice as it provides context for healthcare providers to adjust treatment effectively. Storing strips in the bathroom exposes them to humidity, ignoring unexpected results delays intervention, and sharing lancets risks cross-contamination. A decision-making principle in glucose monitoring is to document contextual factors to identify trends like medication effects. A transferable nursing strategy for monitoring blood glucose levels is to review logs during visits to reinforce education on lifestyle impacts.

Question 8

1. Apply alcohol and test before it dries to prevent contamination
2. Reuse lancets if they look clean to reduce supply costs
3. Use the first drop of blood after squeezing the fingertip firmly to get a larger sample
4. Wash hands with warm soapy water and dry completely before testing (correct answer)

Explanation: This question tests blood glucose monitoring and client safety for a client newly diagnosed with type 2 diabetes using a glucometer. The key client need is accurate self-monitoring technique, especially considering prednisone's effect on elevating glucose levels. The correct answer, washing hands with warm soapy water and drying completely before testing, is the best choice as it prevents contamination from residues that could skew results and promotes capillary blood flow. Using the first drop after firm squeezing may introduce tissue fluid inaccuracies, applying alcohol without drying can dilute the sample or cause errors, and reusing lancets increases infection risk and is not cost-effective in terms of safety. A decision-making principle in glucose monitoring is to prioritize infection control and accuracy in sample collection to ensure reliable data. A transferable nursing strategy for monitoring blood glucose levels is to educate clients on calibrating their glucometer regularly and correlating readings with symptoms for better self-management.

Question 9

1. Client asks for a snack after the glucose is treated
2. Client prefers to use the same finger each time for testing
3. Client states they do not like the taste of sugar-free beverages
4. Capillary blood glucose of 49 mg/dL with palpitations after skipping lunch (correct answer)

Explanation: This question tests blood glucose monitoring and client safety by identifying reportable hypoglycemia in a client with type 2 diabetes. The key assessment finding is a capillary blood glucose of 49 mg/dL with sweating and palpitations after skipping lunch. The correct answer, reporting this low glucose with symptoms, is the best choice as it indicates severe hypoglycemia needing RN oversight. Requests for snacks post-treatment, same-finger use, or disliking sugar-free drinks are non-critical. A decision-making principle in glucose monitoring is to escalate glucose below 50 mg/dL with symptoms promptly. A transferable nursing strategy for monitoring blood glucose levels is to advise on meal timing to prevent hypoglycemic risks from oral agents.

Question 10

1. Instruct the client to skip the next meal to bring the glucose down
2. Delegate teaching on carbohydrate counting to the UAP
3. Assess for symptoms of worsening hyperglycemia and notify the RN/provider of the elevated reading in pregnancy (correct answer)
4. Administer an extra dose of insulin without an order because the glucose is elevated

Explanation: This question tests blood glucose monitoring and client safety in a pregnant client with gestational diabetes experiencing hyperglycemia. The key client need is prompt assessment and reporting due to the risks of elevated glucose on fetal health during pregnancy. The correct answer, assessing for symptoms of worsening hyperglycemia and notifying the RN/provider, is the best choice as it addresses potential maternal and fetal complications like macrosomia or preeclampsia. Instructing to skip the next meal risks hypoglycemia, administering extra insulin without an order violates scope of practice, and delegating teaching to the UAP is inappropriate for complex education. A decision-making principle in glucose monitoring is to maintain tighter control in pregnancy, with targets often below 140 mg/dL postprandial. A transferable nursing strategy for monitoring blood glucose levels is to encourage consistent carbohydrate counting and logging to optimize insulin adjustments.

Question 11

1. Client requests sugar-free gelatin for a bedtime snack
2. Capillary blood glucose of 412 mg/dL with new blurred vision (correct answer)
3. Client states they prefer to test glucose on the forearm
4. Client ate 75% of the dinner tray

Explanation: This question tests blood glucose monitoring and client safety by identifying critical findings to report in a client with type 2 diabetes. The key assessment finding is a capillary blood glucose of 412 mg/dL with new blurred vision and fatigue after a high-carbohydrate meal. The correct answer, reporting the elevated glucose with blurred vision, is the best choice as it indicates severe hyperglycemia requiring prompt RN intervention to prevent complications like hyperosmolar hyperglycemic state. Requesting sugar-free gelatin, preferring forearm testing, or eating 75% of a meal are non-urgent preferences or normal behaviors that do not warrant immediate reporting. A decision-making principle in glucose monitoring is to escalate readings above 300 mg/dL with symptoms for medical evaluation. A transferable nursing strategy for monitoring blood glucose levels is to correlate elevated readings with dietary intake and educate on portion control to maintain glycemic stability.

Question 12

1. Administer the bedtime long-acting insulin to stabilize glucose overnight
2. Call the provider for an order for intravenous dextrose
3. Encourage the client to walk to increase blood sugar naturally
4. Administer 15 g of fast-acting carbohydrate if the client can swallow, then recheck in 15 minutes (correct answer)

Explanation: This question tests blood glucose monitoring and client safety in treating severe hypoglycemia in a young client with type 1 diabetes. The key assessment finding is a capillary blood glucose of 44 mg/dL with pallor, anxiety, and dizziness after skipping a meal. The correct answer, administering 15 g of fast-acting carbohydrate if the client can swallow and rechecking in 15 minutes, is the best choice to safely elevate glucose without overcorrection. Calling for IV dextrose is unnecessary if oral intake is possible, encouraging walking could cause falls, and giving bedtime insulin ignores the current crisis. A decision-making principle in glucose monitoring is to use the rule of 15 for symptomatic hypoglycemia below 70 mg/dL. A transferable nursing strategy for monitoring blood glucose levels is to emphasize meal consistency with insulin dosing to prevent such episodes.

Question 13

1. Check the expiration date on test strips and close the container promptly after removing a strip (correct answer)
2. Clean the lancet with alcohol and reuse it for one week
3. Store test strips in direct sunlight to keep them dry
4. If hands are dirty, wipe the fingertip with a dry tissue before testing

Explanation: This question tests blood glucose monitoring and client safety with emphasis on supply management for accuracy. The key client need is reliable testing, noting risperidone's glucose-elevating effects. The correct answer, checking expiration dates on test strips and closing the container promptly, is the best choice to prevent erroneous readings from degraded strips. Storing in sunlight damages strips, reusing lancets risks infection, and wiping with dry tissue instead of washing allows contaminants. A decision-making principle in glucose monitoring is to ensure equipment integrity for valid results. A transferable nursing strategy for monitoring blood glucose levels is to review medication side effects that influence glucose and adjust monitoring frequency accordingly.

Question 14

1. Follow the prescribed schedule, commonly fasting and 1 or 2 hours after meals, and document results (correct answer)
2. Check after exercise only; food does not significantly affect glucose in pregnancy
3. Check only when you feel symptoms; routine checks are not needed
4. Check at bedtime only because morning readings are less accurate

Explanation: This question tests blood glucose monitoring and client safety for scheduling in gestational diabetes. The key client need is adherence to monitoring to maintain euglycemia during pregnancy. The correct answer, following the prescribed schedule like fasting and post-meal checks with documentation, is the best choice for tracking control and adjusting therapy. Checking only with symptoms misses asymptomatic issues, after exercise only ignores dietary impacts, and bedtime only is insufficient. A decision-making principle in glucose monitoring is to align checks with meals for postprandial insights. A transferable nursing strategy for monitoring blood glucose levels is to use logs to discuss trends and optimize management in high-risk pregnancies.

Question 15

1. Increased appetite before lunch
2. Mild fatigue after eating
3. New confusion and difficulty staying awake (correct answer)
4. Dry mouth and increased urination

Explanation: This question tests blood glucose monitoring and client safety by recognizing severe symptoms in hyperglycemia. The key assessment finding is a capillary blood glucose of 276 mg/dL with urination and dry mouth after a large meal. The correct answer, new confusion and difficulty staying awake, indicates immediate intervention as it suggests possible hyperosmolar state or other complications. Dry mouth and urination are expected, while mild fatigue and increased appetite are less urgent. A decision-making principle in glucose monitoring is to monitor for mental status changes in elevated glucose as they signal emergencies. A transferable nursing strategy for monitoring blood glucose levels is to evaluate elderly clients for atypical presentations and escalate accordingly.

Question 16

1. Increased appetite
2. Dry skin
3. Slow, deep respirations
4. Tingling around the mouth with low glucose reading (correct answer)

Explanation: This question tests blood glucose monitoring and client safety by identifying critical hypoglycemia symptoms requiring prompt action. The key assessment finding is a capillary blood glucose of 66 mg/dL with headache, hunger, and tingling after skipping a meal. The correct answer, tingling around the mouth with low glucose, indicates immediate intervention as it suggests neuroglycopenic progression needing rapid correction. Increased appetite is milder, while dry skin and slow respirations align with hyperglycemia, not this scenario. A decision-making principle in glucose monitoring is to act on glucose below 70 mg/dL with any symptoms to avert severe outcomes. A transferable nursing strategy for monitoring blood glucose levels is to instruct on pairing insulin with meals to prevent hypoglycemic events.

Question 17

1. Recheck the blood glucose to confirm the reading and assess for ketone-related symptoms, then report to the RN (correct answer)
2. Delegate obtaining a urine specimen for glucose to the unlicensed assistive personnel (UAP)
3. Administer the client's scheduled glipizide dose early to lower the glucose quickly
4. Encourage the client to drink water and avoid further concentrated carbohydrates

Explanation: This question tests blood glucose monitoring and client safety in a client with type 2 diabetes experiencing hyperglycemia. The key assessment finding is a capillary blood glucose of 356 mg/dL with symptoms of increased thirst and frequent urination after consuming high-carbohydrate foods. The correct answer, rechecking the blood glucose to confirm the reading and assessing for ketone-related symptoms then reporting to the RN, is the best choice because it ensures accuracy, evaluates for potential diabetic ketoacidosis, and follows the LPN's scope by notifying the RN for further intervention. Encouraging water and avoiding carbohydrates is supportive but not the priority over confirmation and assessment, while administering glipizide early alters the medication schedule without an order and could lead to hypoglycemia; delegating a urine specimen to the UAP is inappropriate as urine glucose testing is less accurate than blood and not the priority action. A decision-making principle in glucose monitoring is to verify elevated readings and assess for complications like ketosis before intervening. A transferable nursing strategy for monitoring blood glucose levels is to maintain a log of readings with contextual details like diet and symptoms to identify patterns and adjust care plans accordingly.

Question 18

1. Document the result and wait for the symptoms to resolve on their own
2. Offer 15 g of fast-acting carbohydrate if the client can swallow safely, then recheck in 15 minutes (correct answer)
3. Encourage the client to drink diet soda to settle the stomach
4. Administer the next scheduled insulin dose to prevent hyperglycemia from stress

Explanation: This question tests blood glucose monitoring and client safety in severe hypoglycemia with neurological symptoms. The key assessment finding is a capillary blood glucose of 40 mg/dL with diaphoresis, shakiness, and slurred speech after vomiting. The correct answer, offering 15 g of fast-acting carbohydrate if safe to swallow and rechecking in 15 minutes, is the best choice to restore glucose levels quickly. Encouraging diet soda provides no glucose, administering insulin exacerbates the issue, and waiting for resolution is dangerous. A decision-making principle in glucose monitoring is to assess swallowing ability before oral treatment in symptomatic hypoglycemia. A transferable nursing strategy for monitoring blood glucose levels is to anticipate glucose drops in illness and adjust insulin proactively.

Question 19

1. Hold the next glucose check because repeated fingersticks can cause infection
2. Delegate insulin administration to the UAP to reduce delays
3. Provide 15 g of fast-acting carbohydrate and recheck in 15 minutes
4. Encourage oral fluids if not contraindicated and notify the RN of the elevated reading and symptoms (correct answer)

Explanation: This question tests blood glucose monitoring and client safety in addressing hyperglycemia in an elderly client with cognitive impairment. The key assessment finding is a capillary blood glucose of 298 mg/dL with nausea and increased urination after consuming cookies. The correct answer, encouraging oral fluids if not contraindicated and notifying the RN, is the best choice to promote hydration and escalate for potential insulin adjustment. Providing fast-acting carbohydrate treats hypoglycemia not hyperglycemia, holding glucose checks risks missing trends, and delegating insulin to UAP exceeds their scope. A decision-making principle in glucose monitoring is to assess hydration status in hyperglycemia to prevent dehydration. A transferable nursing strategy for monitoring blood glucose levels is to involve family in dietary oversight for clients with cognitive challenges.

Question 20

1. Instruct the client to drink only water and rest until symptoms pass
2. Delegate obtaining fetal heart tones to the UAP while the nurse waits to retest later
3. Give 15 g of fast-acting carbohydrate and recheck glucose in 15 minutes (correct answer)
4. Administer an additional dose of insulin to prevent rebound hyperglycemia

Explanation: This question tests blood glucose monitoring and client safety in managing hypoglycemia during pregnancy with gestational diabetes. The key assessment finding is a capillary blood glucose of 60 mg/dL with shakiness and sweating after skipping a snack. The correct answer, giving 15 g of fast-acting carbohydrate and rechecking in 15 minutes, is the best choice to correct low glucose and protect maternal-fetal well-being. Instructing to drink water and rest ignores treatment needs, administering extra insulin worsens hypoglycemia, and delegating fetal monitoring delays immediate care. A decision-making principle in glucose monitoring is to treat hypoglycemia promptly in pregnancy to avoid fetal distress. A transferable nursing strategy for monitoring blood glucose levels is to recommend scheduled snacks to maintain stability in insulin-dependent pregnancies.
