Nursing Elites

1. Nurse Wayne is aware that a positive Chvostek's sign indicates:

• A. Hypocalcemia
• B. Hyponatremia
• C. Hypokalemia
• D. Hypermagnesemia

Correct answer: A

Rationale: A positive Chvostek's sign indicates hypocalcemia. This sign is elicited by tapping the facial nerve anterior to the ear, resulting in facial muscle twitching due to increased neuromuscular irritability from low calcium levels. Hyponatremia (Choice B) is characterized by low sodium levels, but it does not present with Chvostek's sign. Hypokalemia (Choice C) is low potassium levels, and hypermagnesemia (Choice D) is high magnesium levels, neither of which are associated with Chvostek's sign.

2. A client is receiving levothyroxine for hypothyroidism. Which of the following findings would indicate that the medication is effective?

• A. Decreased heart rate
• B. Increased weight
• C. Increased energy levels
• D. Decreased appetite

Correct answer: C

Rationale: The correct answer is C: Increased energy levels. When a client with hypothyroidism is receiving levothyroxine, increased energy levels indicate that thyroid hormone levels are being normalized, which is a positive response to treatment. This improvement reflects the effectiveness of the medication in addressing the underlying hypothyroidism. Choices A, B, and D are incorrect. Decreased heart rate and decreased appetite may be symptoms of hypothyroidism and would not necessarily indicate the effectiveness of levothyroxine. Increased weight could also be a symptom of hypothyroidism and does not directly reflect the medication's effectiveness.

3. A client with type 2 DM is being treated with metformin (Glucophage). The nurse should include which instruction when teaching the client about this medication?

• A. Take the medication with meals.
• B. Take the medication on an empty stomach.
• C. Take the medication before bedtime.
• D. Avoid taking the medication if you miss a meal.

Correct answer: A

Rationale: The correct instruction for a client taking metformin (Glucophage) is to take the medication with meals. This helps reduce gastrointestinal side effects and improves absorption. Choice B is incorrect because taking metformin on an empty stomach can increase the risk of side effects. Choice C is incorrect as there is no specific recommendation to take metformin before bedtime. Choice D is incorrect as missing a meal should not lead to avoiding the medication, but the client should take it with the next meal as prescribed.

4. A client with hypothyroidism is receiving levothyroxine therapy. The healthcare provider should monitor for which of the following signs of medication overdose?

• A. Bradycardia
• B. Weight gain
• C. Tachycardia
• D. Cold intolerance

Correct answer: C

Rationale: The correct answer is C: Tachycardia. Tachycardia is a sign of levothyroxine overdose, indicating that the dose may need to be adjusted. Bradycardia (Choice A) is a sign of hypothyroidism, not an overdose of levothyroxine. Weight gain (Choice B) and cold intolerance (Choice D) are also symptoms of hypothyroidism, not medication overdose.

5. An external insulin pump is prescribed for a client with DM. The client asks the nurse about the functioning of the pump. The nurse bases the response on the information that the pump:

• A. Gives small continuous doses of regular insulin subcutaneously, and the client can self-administer a bolus with an additional dosage from the pump before each meal.
• B. Is timed to release programmed doses of regular or NPH insulin into the bloodstream at specific intervals.
• C. Is surgically attached to the pancreas and infuses regular insulin into the pancreas, which in turn releases the insulin into the bloodstream.
• D. Continuously infuses small amounts of NPH insulin into the bloodstream while regularly monitoring blood glucose levels.

Correct answer: A

Rationale: The correct answer is A. An external insulin pump delivers small continuous doses of regular insulin subcutaneously throughout the day to meet the basal insulin needs. The client can also self-administer a bolus dose with an additional dosage from the pump before each meal to cover the mealtime insulin needs. Option B is incorrect as insulin pumps do not typically release programmed doses of insulin into the bloodstream at specific intervals; instead, they infuse insulin subcutaneously. Option C is incorrect as insulin pumps are not surgically attached to the pancreas; they are worn externally. Option D is incorrect as NPH insulin is not commonly used in insulin pumps, and the pumps do not continuously infuse insulin directly into the bloodstream but rather subcutaneously.
