Blood Glucose Monitoring - NCLEX Pn

1. A 68-year-old client with type 2 diabetes takes metformin and glipizide. At a family party, the client ate two slices of cake and drank regular soda; now reports increased thirst and frequent urination. Capillary blood glucose is 356 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
   Answer: Recheck the blood glucose to confirm the reading and assess for ketone-related symptoms, then report to the RN 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.
2. A 38-year-old client with type 1 diabetes skipped breakfast after taking rapid-acting insulin. The client reports headache, hunger, and tingling around the mouth; capillary blood glucose is 66 mg/dL. Which symptom indicates the need for IMMEDIATE intervention?
   Answer: Tingling around the mouth with low glucose reading 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.
3. A 76-year-old client with type 2 diabetes takes insulin glargine at bedtime and uses sliding-scale insulin aspart. After eating ice cream and sweet tea, the client reports dry mouth and weakness; capillary blood glucose is 462 mg/dL. The nurse should REPORT which finding to the RN?
   Answer: Capillary blood glucose of 462 mg/dL with dry mouth and weakness 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.
4. A 34-year-old client with newly diagnosed diabetes is practicing glucometer technique. The client is taking a beta-blocker (metoprolol) for hypertension, which can mask some hypoglycemia symptoms. Which instruction should the nurse REINFORCE for a client learning to use a glucometer?
   Answer: Rotate fingerstick sites and use the sides of the fingertip rather than the pad 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.
5. A 31-year-old client with type 1 diabetes took rapid-acting insulin but vomited and did not eat. The client is diaphoretic, shaky, and has slurred speech; capillary blood glucose is 40 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
   Answer: Offer 15 g of fast-acting carbohydrate if the client can swallow safely, then recheck in 15 minutes 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.
6. A 55-year-old client with type 2 diabetes takes glipizide. The client skipped lunch due to a long meeting and now reports sweating and palpitations; capillary blood glucose is 49 mg/dL. The nurse should REPORT which finding to the RN?
   Answer: Capillary blood glucose of 49 mg/dL with palpitations after skipping lunch 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.
7. A 60-year-old client with type 2 diabetes takes glyburide and metformin. The client skipped breakfast for lab work and now reports sweating, trembling, and irritability; capillary blood glucose is 58 mg/dL. Which symptom indicates the need for IMMEDIATE intervention?
   Answer: Trembling and diaphoresis 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.
8. A 66-year-old client with type 2 diabetes takes insulin detemir and insulin aspart. After eating pizza, cake, and regular soda, the client becomes drowsy and complains of nausea; capillary blood glucose is 508 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
   Answer: Assess level of consciousness, encourage fluids if allowed, and notify the RN immediately of the severe hyperglycemia This question tests blood glucose monitoring and client safety in severe hyperglycemia with altered status. The key assessment finding is a capillary blood glucose of 508 mg/dL with drowsiness and nausea after high-carb intake. The correct answer, assessing level of consciousness, encouraging fluids if allowed, and notifying the RN immediately, is the best choice to address potential hyperosmolar crisis. Providing carbohydrate worsens hyperglycemia, administering insulin without order is unsafe, and delegating a delayed check ignores urgency. A decision-making principle in glucose monitoring is to prioritize notification for glucose over 500 mg/dL with mental changes. A transferable nursing strategy for monitoring blood glucose levels is to assess for dehydration and promote hydration in hyperglycemic states.
9. A 73-year-old client with type 2 diabetes takes metformin and a morning dose of insulin NPH. After eating a large breakfast with donuts, the client reports increased urination and dry mouth; capillary blood glucose is 276 mg/dL. Which symptom indicates the need for IMMEDIATE intervention?
   Answer: New confusion and difficulty staying awake 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.
10. A 27-year-old pregnant client with gestational diabetes takes insulin with meals. The client skipped the afternoon snack due to an appointment and now feels shaky and sweaty; capillary blood glucose is 60 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
    Answer: Give 15 g of fast-acting carbohydrate and recheck glucose in 15 minutes 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.
11. A 29-year-old pregnant client at 30 weeks with gestational diabetes is monitoring glucose at home and is taking insulin as prescribed. Today the client ate a breakfast of pancakes and syrup and now feels very thirsty and has a headache; capillary blood glucose in clinic is 228 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
    Answer: Assess for symptoms of worsening hyperglycemia and notify the RN/provider of the elevated reading in pregnancy 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.
12. A 23-year-old client with type 1 diabetes uses rapid-acting insulin with meals and long-acting insulin at bedtime. The client skipped lunch due to nausea and now has shakiness, sweating, and confusion. Capillary blood glucose is 52 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
    Answer: Give 15 g of fast-acting carbohydrate (such as 4 ounces of juice) and recheck glucose in 15 minutes This question tests blood glucose monitoring and client safety in managing hypoglycemia for a client with type 1 diabetes. The key assessment finding is a capillary blood glucose of 52 mg/dL with symptoms of shakiness, sweating, and confusion after skipping a meal. The correct answer, giving 15 g of fast-acting carbohydrate and rechecking in 15 minutes, is the best choice as it follows the rule of 15 to rapidly correct hypoglycemia and prevent neurological complications. Administering long-acting insulin would worsen hypoglycemia, encouraging a full meal before treatment delays correction, and delegating vital signs distracts from the immediate need to treat low glucose. A decision-making principle in glucose monitoring is to treat hypoglycemia promptly if the reading is below 70 mg/dL and the client is symptomatic. A transferable nursing strategy for monitoring blood glucose levels is to advise clients on recognizing early hypoglycemia signs and keeping fast-acting carbohydrates readily available.

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.
16. A 19-year-old client with type 1 diabetes took rapid-acting insulin but then skipped dinner due to nausea. The client is pale, anxious, and reports dizziness; capillary blood glucose is 44 mg/dL. What is the nurse's PRIORITY action after obtaining this blood glucose reading?
    Answer: Administer 15 g of fast-acting carbohydrate if the client can swallow, then recheck in 15 minutes 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.
17. A 45-year-old client newly diagnosed with type 2 diabetes is learning to use a glucometer. The client takes prednisone for asthma exacerbations and reports higher sugars since starting it. Which instruction should the nurse REINFORCE for a client learning to use a glucometer?
    Answer: Wash hands with warm soapy water and dry completely before testing 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.
18. A 70-year-old client with type 2 diabetes takes insulin NPH in the morning and has mild cognitive impairment. After eating cookies brought by family, the client reports nausea and increased urination; capillary blood glucose is 298 mg/dL.
