NCLEX-RN › Insulin Regimens And Hypoglycemia Management
A 52-year-old client with type 2 diabetes is in an outpatient clinic for follow-up. The current insulin regimen is insulin NPH 10 units subcutaneously at 0700 and 10 units at 1900, plus insulin regular 5 units subcutaneously 30 minutes before breakfast and dinner. The client reports waking at night with sweating and palpitations; a 0300 blood glucose check was 54 mg/dL (expected fasting 70–99 mg/dL). History includes recent decreased evening food intake to lose weight. The nurse should QUESTION which part of the client's insulin regimen?
The evening NPH dose timing because its peak can occur overnight and contribute to nocturnal hypoglycemia
The recommendation to check blood glucose at bedtime when adjusting insulin
The use of insulin regular 30 minutes before meals because it should be given immediately after meals
The practice of cleaning the injection site with mild soap and water
Explanation
This question tests application of insulin regimen analysis for nocturnal hypoglycemia patterns. The priority concern is identifying the cause of nighttime hypoglycemia (54 mg/dL at 0300) with classic symptoms. Questioning the evening NPH dose timing (Option A) is correct because NPH given at 1900 peaks during sleep (2-4 AM), causing nocturnal hypoglycemia, especially with decreased evening food intake. Regular insulin timing before meals (Option B) is correct at 30 minutes; bedtime glucose monitoring (Option C) is appropriate; injection site cleaning (Option D) is acceptable practice. The nursing principle recognizes that evening NPH doses frequently cause overnight hypoglycemia due to peak action during sleep when counter-regulatory responses are diminished. For effective insulin management, consider switching evening NPH to bedtime or using a peakless basal insulin to reduce nocturnal hypoglycemia risk.
A 28-year-old client with type 1 diabetes is seen in an outpatient clinic for insulin education. The regimen is insulin glargine 22 units subcutaneously at bedtime and insulin lispro with meals using carbohydrate counting. Recent self-monitoring shows pre-lunch blood glucose values of 58–65 mg/dL for the last 3 days (expected fasting 70–99 mg/dL), and the client reports mid-day shakiness and sweating. History includes recent increase in exercise during lunch breaks. What teaching point is MOST important for the client regarding insulin administration?
Carry a fast-acting glucose source at all times and treat symptoms with 15 g carbohydrate, then recheck in 15 minutes
Take insulin lispro 2 hours after eating to reduce the risk of hypoglycemia
Use regular insulin instead of insulin lispro because it lasts longer
Skip insulin glargine on days you plan to exercise at lunchtime
Explanation
This question tests application of insulin management and hypoglycemia prevention education. The priority concern is teaching proper hypoglycemia recognition and treatment for a patient experiencing recurrent mid-day hypoglycemia related to increased exercise. Teaching to carry fast-acting glucose and use the 15-15 rule (Option B) provides the most important safety information for managing hypoglycemia episodes. Taking insulin lispro 2 hours after eating (Option A) would cause postprandial hyperglycemia; skipping basal insulin on exercise days (Option C) disrupts glucose control and increases ketosis risk; switching to regular insulin (Option D) doesn't address the exercise-induced hypoglycemia pattern. The nursing principle emphasizes that all insulin-dependent patients must understand hypoglycemia treatment protocols and always have rapid-acting glucose available. For effective insulin management, teach patients to adjust carbohydrate intake or insulin doses when increasing physical activity rather than skipping doses.
A 62-year-old client with type 2 diabetes is hospitalized for pneumonia. The client’s current insulin regimen is insulin glargine 20 units subcutaneously at bedtime and insulin lispro 6 units subcutaneously with meals. One hour after receiving insulin lispro for lunch, the client reports shakiness and diaphoresis; blood glucose is 52 mg/dL (expected fasting 70–99 mg/dL). Medical history includes chronic kidney disease stage 3 and hypertension. Which action should the nurse take FIRST in response to the client's hypoglycemia?
Start an intravenous infusion of regular insulin per sliding-scale protocol
Administer 15 g of rapid-acting carbohydrate (eg, 4 oz juice) and recheck blood glucose in 15 minutes
Administer 1 mg glucagon intramuscularly and place the client in high-Fowler position
Hold the next scheduled dose of insulin glargine and notify the provider
Explanation
This question tests application of insulin management and hypoglycemia intervention in a hospitalized diabetic patient. The priority concern is immediate correction of hypoglycemia with a blood glucose of 52 mg/dL, which requires rapid intervention to prevent neurological complications. Administering 15 g of rapid-acting carbohydrate orally and rechecking in 15 minutes (Option A) is the correct first-line treatment for conscious patients who can swallow safely. Holding insulin glargine (Option B) addresses future prevention but not the immediate crisis; glucagon (Option C) is reserved for patients unable to take oral carbohydrates or unconscious patients; and IV insulin (Option D) would worsen hypoglycemia and is contraindicated. The 15-15 rule is the standard nursing intervention for hypoglycemia: give 15 g carbohydrate, wait 15 minutes, and recheck blood glucose. For NCLEX success, remember that immediate treatment of symptomatic hypoglycemia always takes priority over adjusting future insulin doses.
A 48-year-old client with type 2 diabetes is admitted for pancreatitis and is on a clear liquid diet. Current regimen: NPH insulin 12 units at 0700 and regular insulin 4 units at 0630. At 1000, the client is diaphoretic with tremors; blood glucose is 57 mg/dL (normal fasting 70–100 mg/dL). The client is alert and able to swallow. Which action should the nurse take FIRST in response to the client's hypoglycemia?
Give 15 g rapid-acting carbohydrate (eg, clear juice) and recheck blood glucose in 15 minutes
Provide a high-fat snack to slow glucose absorption
Administer the next dose of NPH insulin early to prevent hyperglycemia
Notify the provider to discontinue the clear liquid diet
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a client with type 2 diabetes on a liquid diet. The priority concern is symptomatic hypoglycemia with blood glucose of 57 mg/dL, needing immediate correction compatible with diet. Giving 15 g rapid-acting carbohydrate like clear juice and rechecking in 15 minutes best addresses this for an alert client able to swallow. Administering NPH early risks more lows; high-fat snack is inappropriate; discontinuing diet ignores nutrition. Liquid diets require glucose sources. Symptom assessment guides urgency. A transferable strategy is to adapt treatments to dietary restrictions in insulin-managed hypoglycemia.
A 58-year-old client with type 2 diabetes is seen in an outpatient clinic. Current regimen: NPH insulin 14 units at 0700 and 10 units at 1900, plus regular insulin 6 units 30 minutes before breakfast and dinner. The client reports inconsistent meal times due to shift work and has had midafternoon blood glucose readings of 55–65 mg/dL (normal fasting 70–100 mg/dL) with shakiness. What teaching point is MOST important for the client regarding insulin administration?
Plan a consistent meal schedule and include a midafternoon snack to reduce NPH-related lows
Treat blood glucose under 100 mg/dL with a full meal to prevent hypoglycemia
Take regular insulin immediately after eating to better match food intake
Double the evening NPH dose on days you skip lunch
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a client with type 2 diabetes and inconsistent meals. The priority concern is preventing midafternoon hypoglycemia from NPH insulin peaking, as seen in readings of 55–65 mg/dL with shakiness. Planning a consistent meal schedule with a midafternoon snack best addresses this by aligning intake with NPH's action profile. Taking regular insulin after eating mismatches its onset; doubling evening NPH on skipped lunch days risks overdose; treating under 100 mg/dL with a full meal is excessive. Consistent timing reduces hypoglycemia risk in intermediate-acting insulins. Education on insulin pharmacokinetics aids self-management. A transferable strategy is to synchronize meals and snacks with insulin peaks for stable glucose in regimens using NPH.
A 70-year-old client with type 2 diabetes is admitted for chronic obstructive pulmonary disease exacerbation. Current regimen: NPH insulin 18 units at 0800 and regular insulin 6 units at 0730. At 1100, the client is sweaty and irritable; blood glucose is 59 mg/dL (normal fasting 70–100 mg/dL). The client is alert and requesting water. Which action should the nurse take FIRST in response to the client's hypoglycemia?
Provide 15 g of rapid-acting carbohydrate and recheck blood glucose in 15 minutes
Give 2 liters oxygen via nasal cannula to treat irritability
Offer a full meal tray and recheck blood glucose at the next routine check
Administer the next scheduled dose of regular insulin to prevent rebound hyperglycemia
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a hospitalized client with type 2 diabetes and COPD. The priority concern is symptomatic hypoglycemia with blood glucose of 59 mg/dL, needing immediate correction in an alert client. Providing 15 g of rapid-acting carbohydrate and rechecking in 15 minutes best addresses this for rapid elevation. Administering regular insulin worsens it; offering a full meal delays; oxygen is unrelated. Post-insulin timing requires vigilance. Alertness assessment ensures oral safety. A transferable strategy is to integrate comorbidity effects into glucose monitoring for insulin regimens.
A 52-year-old client with type 2 diabetes is in an outpatient clinic for education. Current regimen: insulin glargine 30 units at bedtime and insulin aspart 8 units with meals. The client reports fasting blood glucose readings of 68–75 mg/dL (normal fasting 70–100 mg/dL) on 4 of the last 7 mornings and waking with headache and sweating. Relevant history: chronic kidney disease stage 3. What teaching point is MOST important for the client regarding insulin administration?
Take insulin aspart at bedtime to prevent morning lows
Recognize nocturnal hypoglycemia symptoms and treat blood glucose under 70 mg/dL using the 15-15 rule
Skip the bedtime insulin glargine whenever fasting blood glucose is under 100 mg/dL
Avoid checking blood glucose when you feel symptoms because it can increase anxiety
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a client with type 2 diabetes and kidney disease. The priority concern is recurrent nocturnal hypoglycemia, indicated by low fasting glucose and symptoms like headache and sweating. Teaching to recognize nocturnal symptoms and treat under 70 mg/dL using the 15-15 rule is most important for self-management. Taking aspart at bedtime mismatches its use; avoiding checks increases risk; skipping glargine for low fasting is inappropriate. Kidney disease can prolong insulin action, heightening hypoglycemia risk. Nighttime monitoring prevents severe episodes. A transferable strategy is to review glucose patterns and adjust basal insulin with providers for effective regimen stability.
A 66-year-old client with type 2 diabetes is hospitalized for heart failure exacerbation. Current regimen: insulin glargine 24 units at 2100 and insulin lispro 6 units with meals. Recent readings: 0700 blood glucose 110 mg/dL; 1200 blood glucose 58 mg/dL (normal fasting 70–100 mg/dL) with dizziness and diaphoresis. The lunch tray has arrived and the client is alert. Which action should the nurse take FIRST in response to the client's hypoglycemia?
Give 15 g rapid-acting carbohydrate before the meal and recheck blood glucose in 15 minutes
Administer the scheduled insulin lispro with the lunch tray to prevent hyperglycemia
Encourage the client to eat the entire lunch tray and recheck blood glucose in 2 hours
Notify the provider to discontinue all insulin therapy
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a hospitalized client with type 2 diabetes and heart failure. The priority concern is symptomatic hypoglycemia with blood glucose of 58 mg/dL at mealtime, needing immediate correction before eating. Giving 15 g rapid-acting carbohydrate before the meal and rechecking in 15 minutes best addresses this to safely raise glucose for an alert client. Administering lispro now worsens the low; encouraging full tray intake delays treatment; discontinuing insulin is unsafe. Pre-meal hypoglycemia requires fast-acting intervention. Monitoring ensures resolution before proceeding. A transferable strategy is to treat lows promptly even at mealtimes to maintain safety in insulin regimens.
A 42-year-old client with type 1 diabetes is in an outpatient clinic for review of glucose logs. Current regimen: insulin glargine 20 units at bedtime and insulin aspart with meals. The client reports frequent pre-dinner blood glucose readings of 58–68 mg/dL (normal fasting 70–100 mg/dL) with shakiness on days they skip lunch. Relevant history: no cardiovascular disease. What teaching point is MOST important for the client regarding insulin administration?
Avoid checking blood glucose before dinner because it can vary day to day
Use insulin glargine to correct low blood glucose because it lasts longer
Carry a fast-acting carbohydrate source and treat blood glucose under 70 mg/dL promptly
If you skip lunch, you should still take your usual mealtime insulin dose to prevent ketones
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a client with type 1 diabetes and skipped meals. The priority concern is preventing hypoglycemia on days meals are missed, as in pre-dinner lows of 58–68 mg/dL. Teaching to carry fast-acting carbohydrates and treat under 70 mg/dL promptly is most important for safety. Taking mealtime insulin when skipping risks lows; using glargine to correct is incorrect; avoiding checks misses opportunities. Meal skipping requires bolus omission. Consistent monitoring prevents complications. A transferable strategy is to adapt bolus doses to actual intake for stable insulin regimens.
A 74-year-old client with type 2 diabetes is admitted for cellulitis. Current regimen: insulin glargine 26 units at bedtime and insulin lispro 7 units with meals. At 1600, the client is confused and diaphoretic; blood glucose is 54 mg/dL (normal fasting 70–100 mg/dL). Vital signs: T 99.1°F (37.3°C), HR 112/min, RR 18/min, BP 146/82 mm Hg. The client is awake and can swallow. Which action should the nurse take FIRST in response to the client's hypoglycemia?
Provide a high-protein snack and recheck blood glucose in 1 hour
Administer 15 g rapid-acting carbohydrate and recheck blood glucose in 15 minutes
Obtain an order to start an insulin infusion for tighter glucose control
Administer insulin lispro now to prevent infection-related hyperglycemia
Explanation
This question tests the application of insulin management and hypoglycemia intervention in a hospitalized client with type 2 diabetes and infection. The priority concern is symptomatic hypoglycemia with blood glucose of 54 mg/dL, needing immediate correction in an awake client able to swallow. Administering 15 g rapid-acting carbohydrate and rechecking in 15 minutes best addresses this for quick glucose rise. Giving lispro now worsens it; starting infusion is for critical cases; high-protein snack is slower-acting. Infections can alter glucose needs, but acute lows require priority treatment. Vital signs monitoring aids assessment. A transferable strategy is to anticipate insulin adjustments during illness for regimen effectiveness.
