Nursing Elites

1. Which electrolyte imbalance is most concerning for a patient on furosemide?

• A. Hypokalemia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is hypokalemia. Furosemide, a loop diuretic, can lead to potassium loss through increased urinary excretion, making hypokalemia the most concerning electrolyte imbalance. Hyponatremia (Choice B) is not typically associated with furosemide use. Hyperkalemia (Choice C) is less likely due to furosemide's potassium-wasting effect. Hypercalcemia (Choice D) is not a common electrolyte imbalance seen with furosemide.

2. A nurse is preparing to administer a controlled substance. Which of the following actions should the nurse take?

• A. Witness the waste of the controlled substance by another nurse
• B. Dispose of the controlled substance by yourself
• C. Leave the controlled substance in the client's room for later use
• D. Document the administration and sign off at the end of the shift

Correct answer: A

Rationale: The correct action for the nurse preparing to administer a controlled substance is to witness the waste of the controlled substance by another nurse. This practice is crucial to prevent misuse and ensure accurate documentation. Choice B is incorrect because disposing of the controlled substance by oneself without proper witnessing is not in accordance with safety protocols. Choice C is incorrect as leaving a controlled substance unattended in a client's room poses risks of diversion or unauthorized access. Choice D is incorrect because documenting the administration and signing off at the end of the shift is important but does not specifically address the issue of witnessing the waste of a controlled substance, which is a critical step in ensuring proper handling and accountability.

3. Which diagnostic test is used to confirm tuberculosis (TB) infection?

• A. Chest X-ray
• B. Sputum culture
• C. Skin test (Mantoux)
• D. MRI

Correct answer: C

Rationale: The Mantoux skin test, also known as the Tuberculin Skin Test (TST), is used to confirm tuberculosis (TB) infection. This test involves injecting a small amount of tuberculin protein derivative under the top layer of the skin and then evaluating the immune system's response to the protein. A positive reaction indicates exposure to the TB bacteria. Chest X-rays are used to detect abnormalities in the lungs caused by TB but are not confirmatory. Sputum culture is used to identify the presence of TB bacteria in the sputum. MRIs are not typically used as a primary diagnostic tool for TB.

4. A nurse is providing discharge teaching to a client who is postoperative following a total hip arthroplasty. Which of the following instructions should the nurse include?

• A. Cross your legs when sitting to increase circulation.
• B. Bend at the waist when picking up objects.
• C. Avoid crossing your legs when sitting.
• D. Avoid using a raised toilet seat.

Correct answer: C

Rationale: The correct answer is C: 'Avoid crossing your legs when sitting.' After a total hip arthroplasty, it is important for clients to avoid crossing their legs to prevent complications such as dislocation. Crossing the legs can put strain on the new hip joint, increasing the risk of dislocation. Choice A is incorrect as crossing legs can be harmful. Choice B is incorrect as bending at the waist can strain the hip joint, leading to complications. Choice D is incorrect as using a raised toilet seat is recommended after hip surgery to prevent excessive bending at the hip joint.

5. A nurse is caring for a client who has a new prescription for nitroglycerin transdermal patches. Which of the following instructions should the nurse include?

• A. Apply the patch to the same location each time.
• B. Rotate the patch site daily to avoid skin irritation.
• C. Apply the patch in the morning and remove it at bedtime.
• D. Keep the patch on at all times, even during a bath.

Correct answer: C

Rationale: The correct answer is to apply the nitroglycerin transdermal patch in the morning and remove it at bedtime. This schedule helps prevent tolerance to the medication. Choice A is incorrect because the patch should be rotated to different sites to prevent skin irritation. Choice B is incorrect as daily rotation is recommended, not daily application to the same site. Choice D is incorrect as the patch should be removed during a bath as it may decrease the efficacy of the medication.
