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. Capillary glucose monitoring is being performed every 4 hours for a female client diagnosed with diabetic ketoacidosis. Insulin is administered using a scale of regular insulin according to glucose results. At 2 p.m., the client has a capillary glucose level of 250 mg/dl for which she receives 8 U of regular insulin. Nurse Vince should expect the dose's:

• A. Onset to be at 2 p.m. and its peak to be at 3 p.m.
• B. Onset to be at 2:15 p.m. and its peak to be at 3 p.m.
• C. Onset to be at 2:30 p.m. and its peak to be at 4 p.m.
• D. Onset to be at 4 p.m. and its peak to be at 6 p.m.

Correct answer: C

Rationale: The correct answer is C. Regular insulin typically has an onset of action within 30 minutes and peaks 2-4 hours after administration. Given that the insulin was administered at 2 p.m., the onset of action can be expected around 2:30 p.m., and the peak effect would occur between 4-6 p.m. Choice A is incorrect as the onset and peak are too close together for regular insulin. Choice B is incorrect because the onset time is too soon after administration. Choice D is incorrect as the onset time is too delayed for regular insulin.

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. The healthcare provider is providing dietary instructions to a client with hyperthyroidism. Which of the following foods should the client avoid?

• A. Seafood
• B. Spinach
• C. Bananas
• D. Oatmeal

Correct answer: A

Rationale: The client with hyperthyroidism should avoid foods high in iodine, as it can exacerbate the condition by increasing thyroid hormone production. Seafood, particularly ocean fish, is rich in iodine, making it a food to avoid. Spinach, bananas, and oatmeal do not contain high levels of iodine and are generally safe for individuals with hyperthyroidism.

5. Which of the following is an example of nonmaleficence in nursing practice?

• A. Administering pain medication as prescribed to prevent patient discomfort.
• B. Ensuring that a patient does not receive a treatment that they have refused.
• C. Ensuring that a patient receives appropriate care without causing harm.
• D. Encouraging a patient to express their concerns and fears about a procedure.

Correct answer: B

Rationale: Nonmaleficence is the ethical principle of doing no harm. In nursing practice, ensuring that a patient does not receive a treatment they have refused is an example of nonmaleficence. Choice A focuses on beneficence by providing pain relief. Choice C is more aligned with beneficence as it emphasizes providing appropriate care without harm. Choice D pertains to patient communication but does not directly address the concept of nonmaleficence.
