Nursing Elites

1. A client with diabetes mellitus is experiencing hyperglycemia. What laboratory value should the nurse monitor to evaluate long-term glucose control?

• A. Blood glucose level
• B. Glycosylated hemoglobin (A1C)
• C. Urine output
• D. Serum ketone level

Correct answer: B

Rationale: The correct answer is B: Glycosylated hemoglobin (A1C). Glycosylated hemoglobin reflects long-term glucose control over the past three months. Monitoring blood glucose levels provides information on the current glucose status and immediate control, but it does not give a comprehensive view of long-term control. Urine output and serum ketone levels are important indicators for other aspects of diabetes management, such as hydration status and ketone production during hyperglycemic episodes, but they do not directly reflect long-term glucose control.

2. A nurse assesses a young adult in the emergency room following a motor vehicle accident. Which of the following neurological signs is of most concern?

• A. Flaccid paralysis
• B. Pupils fixed and dilated
• C. Diminished spinal reflexes
• D. Reduced sensory responses

Correct answer: B

Rationale: Fixed, dilated pupils are a sign of increased intracranial pressure or brain injury, indicating a potentially serious neurological condition. Flaccid paralysis, although concerning, may not always indicate immediate life-threatening issues. Diminished spinal reflexes and reduced sensory responses are important neurological assessments but are not as acutely concerning as fixed, dilated pupils in this context.

3. A client with Type 1 diabetes reports feeling shaky and lightheaded. The nurse checks the client's blood glucose level and it is 60 mg/dL. What action should the nurse take first?

• A. Give the client a glucagon injection
• B. Encourage the client to eat a high-protein snack
• C. Recheck the blood glucose level in 15 minutes
• D. Administer 15 grams of a fast-acting carbohydrate

Correct answer: D

Rationale: The correct answer is D: Administer 15 grams of a fast-acting carbohydrate. The first step in treating hypoglycemia is to quickly raise the client's blood sugar level. Fast-acting carbohydrates like glucose tablets or juice are essential for this purpose. Giving a glucagon injection is typically reserved for severe hypoglycemia when the client is unable to take anything by mouth. Encouraging the client to eat a high-protein snack is not appropriate for immediate treatment of hypoglycemia. Rechecking the blood glucose level in 15 minutes is important after administering the fast-acting carbohydrate to ensure that the blood sugar has returned to a safe level.

4. A postoperative client with a history of diabetes mellitus is showing signs of hyperglycemia. What should the nurse assess first?

• A. Assess for signs of infection.
• B. Monitor the client’s fluid intake and output.
• C. Check the client’s capillary blood glucose level.
• D. Assess the client’s serum potassium level.

Correct answer: C

Rationale: The correct answer is to check the client’s capillary blood glucose level first. In a postoperative client with a history of diabetes mellitus showing signs of hyperglycemia, assessing blood glucose levels is crucial to confirm hyperglycemia and initiate appropriate interventions. While signs of infection are important to assess due to the client's postoperative status and diabetic history, checking the blood glucose level takes precedence to address the immediate concern of hyperglycemia. Monitoring fluid intake and output is essential but not the priority in this scenario. Assessing the client’s serum potassium level is important for overall assessment but not the initial step when hyperglycemia is suspected.

5. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.
