1. A client is taking NPH insulin daily every morning. The nurse instructs the client that the most likely time for a hypoglycemic reaction to occur is:
- A. 2-4 hours after administration
- B. 6-14 hours after administration
- C. 16-18 hours after administration
- D. 18-24 hours after administration
Correct answer: B
Rationale: The correct answer is B: 6-14 hours after administration. NPH insulin has an onset of action within 1-2 hours, a peak action at 6-14 hours, and a duration of action of 16-24 hours. The peak action period, which is when the risk of hypoglycemia is highest, falls between 6-14 hours after administration. Choices A, C, and D are incorrect because they do not align with the typical action profile of NPH insulin.
2. The healthcare provider prescribes a sepsis protocol for a client with multi-organ failure caused by a ruptured appendix. Which intervention is most important for the nurse to include in the care plan?
- A. Ensure early ambulation
- B. Administer antibiotics as prescribed
- C. Maintain strict intake and output
- D. Monitor blood glucose levels
Correct answer: C
Rationale: In sepsis with multi-organ failure, monitoring intake and output is critical to assess renal function and fluid balance, as organ failure can cause fluid shifts and decreased kidney function. Antibiotics are essential to treat the infection, but monitoring intake and output provides real-time insight into the client's status, helping to detect early signs of worsening organ function. Early ambulation and blood glucose monitoring are important aspects of care but are not as crucial as maintaining strict intake and output in this situation.
3. The healthcare provider is caring for a client with hypokalemia. Which assessment finding requires immediate intervention?
- A. Muscle weakness.
- B. Irregular heart rate.
- C. Increased urinary output.
- D. Decreased deep tendon reflexes.
Correct answer: D
Rationale: Decreased deep tendon reflexes are a critical finding in hypokalemia that indicates severe potassium deficiency affecting neuromuscular function. Immediate intervention is necessary to prevent life-threatening complications such as respiratory failure or cardiac arrhythmias. Muscle weakness, irregular heart rate, and increased urinary output are also associated with hypokalemia but do not pose the same level of urgency as decreased deep tendon reflexes.
4. The nurse plans to administer a scheduled dose of metoprolol (Toprol SR) at 0900 to a client with hypertension. At 0800, the nurse notes that the client's telemetry pattern shows a second-degree heart block with a ventricular rate of 50. What action should the nurse take?
- A. Administer the Toprol immediately and monitor the client until the heart rate increases.
- B. Provide the dose of Toprol as scheduled and assign a UAP to monitor the client's BP q30 minutes.
- C. Give the Toprol as scheduled if the client's systolic blood pressure reading is greater than 180.
- D. Hold the scheduled dose of Toprol and notify the healthcare provider of the telemetry pattern.
Correct answer: D
Rationale: In clients with second-degree heart block, beta blockers such as metoprolol (Toprol SR) are contraindicated as they can further decrease the heart rate. Administering metoprolol in this situation can lead to serious complications. The correct action for the nurse to take is to hold the scheduled dose of Toprol and promptly notify the healthcare provider of the telemetry pattern. This ensures patient safety and appropriate management of the cardiac condition. Choices A, B, and C are incorrect because administering Toprol despite the heart block can worsen the condition and pose a risk to the client's health.
5. A young adult male is admitted to the emergency department with diabetic ketoacidosis (DKA). His pH is 7.25, HCO3 is 12 mEq/L, and blood glucose is 310 mg/dl. Which action should the nurse implement?
- A. Infuse sodium chloride 0.9% (normal saline)
- B. Prepare an emergency dose of glucagon
- C. Determine the last time the client ate
- D. Check urine for ketone bodies with a dipstick
Correct answer: A
Rationale: In DKA, restoring fluid balance with sodium chloride is a priority to address the dehydration and electrolyte imbalances present in this condition. Choice B, preparing an emergency dose of glucagon, is incorrect because DKA is characterized by insulin deficiency, not glucagon deficiency. Choice C, determining the last time the client ate, is not the immediate priority in managing DKA. Choice D, checking urine for ketone bodies with a dipstick, may help confirm the diagnosis of DKA but is not the most critical intervention at this time.
