Nursing Elites

1. A nurse caring for a client with hypocalcemia would expect to note which of the following changes on the electrocardiogram?

• A. Widened T wave
• B. Prominent U wave
• C. Prolonged QT interval
• D. Shortened ST segment

Correct answer: C

Rationale: In hypocalcemia, a decreased level of calcium can lead to a prolonged QT interval on the ECG due to its role in myocardial repolarization. A widened T wave (Choice A) is typically seen in hyperkalemia. A prominent U wave (Choice B) is associated with hypokalemia. A shortened ST segment (Choice D) is not a typical ECG finding in hypocalcemia.

2. The client with type 1 diabetes mellitus is being educated by the nurse about the signs of hypoglycemia. Which of the following symptoms should the client be instructed to report immediately?

• A. Shakiness
• B. Sweating
• C. Confusion
• D. Increased thirst

Correct answer: C

Rationale: Confusion is a critical symptom of hypoglycemia that may indicate a more severe drop in blood glucose levels. Immediate reporting of confusion is crucial as it could progress rapidly to unconsciousness or seizures, necessitating prompt intervention. Shakiness and sweating are common early signs of hypoglycemia but may not require immediate intervention unless other severe symptoms present. Increased thirst is more indicative of hyperglycemia rather than hypoglycemia, and while it should be monitored, it is not a symptom requiring immediate reporting.

3. A client with type 2 diabetes mellitus is prescribed metformin. The nurse should monitor the client for which of the following potential side effects?

• A. Lactic acidosis
• B. Hypokalemia
• C. Hyperglycemia
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A, lactic acidosis. Metformin, a common medication for type 2 diabetes mellitus, can lead to lactic acidosis, particularly in individuals with renal impairment or predisposing factors. Monitoring for signs of lactic acidosis, such as muscle pain, weakness, trouble breathing, dizziness, and slow or uneven heart rate, is crucial to prevent serious complications. Choices B, C, and D are incorrect as metformin does not typically cause hypokalemia, hyperglycemia, or weight gain as its primary side effects.

4. A patient with acute congestive heart failure is receiving high doses of a diuretic. On assessment, the nurse notes flat neck veins, generalized muscle weakness, and diminished deep tendon reflexes. Suspecting hyponatremia, what additional signs would the nurse expect to note in this patient if hyponatremia were present?

• A. Dry skin
• B. Decreased urinary output
• C. Hyperactive bowel sounds
• D. Increased specific gravity of the urine

Correct answer: C

Rationale: In a patient with hyponatremia, hyperactive bowel sounds are expected due to increased gastrointestinal motility. Dry skin (Choice A) is not a typical sign of hyponatremia. Decreased urinary output (Choice B) is more commonly associated with conditions like dehydration or renal issues, not specifically hyponatremia. Increased specific gravity of the urine (Choice D) is a sign of concentrated urine, which is not a characteristic finding in hyponatremia.

5. A client with DM is taking regular and NPH insulin every morning. The nurse should provide which instruction to the client?

• A. Take the regular insulin first, then the NPH insulin.
• B. Take the NPH insulin first, then the regular insulin.
• C. Mix the insulins in a separate syringe.
• D. Take the regular insulin first and immediately follow it with the NPH insulin.

Correct answer: A

Rationale: The correct instruction for the client is to take the regular insulin first, then the NPH insulin. Regular insulin should be administered before NPH insulin to prevent contamination and maintain the potency of each insulin type. Choice B is incorrect because NPH insulin should not be taken before regular insulin. Mixing the insulins in a separate syringe, as suggested in choice C, is not recommended as it may alter the effectiveness of the insulins. Choice D is also incorrect as taking the regular insulin first and immediately following it with NPH insulin is not the recommended administration sequence.
