Nursing Elites

1. What can cause a low pulse oximetry reading?

• A. Hyperthermia
• B. Increased hemoglobin level
• C. Inadequate peripheral circulation
• D. Low altitudes

Correct answer: C

Rationale: Inadequate peripheral circulation can cause a low pulse oximetry reading by limiting blood flow to the area being measured, leading to inaccurate oxygen saturation readings. Hyperthermia (choice A) is an elevated body temperature and does not directly affect pulse oximetry readings. An increased hemoglobin level (choice B) would actually lead to higher oxygen-carrying capacity in the blood, resulting in normal or increased pulse oximetry readings. Low altitudes (choice D) typically do not cause low pulse oximetry readings unless there are other underlying conditions affecting oxygen levels.

2. A nurse is caring for a client prescribed lisinopril. Which of the following medication interactions should the nurse instruct this client about?

• A. Potassium supplements
• B. Ciprofloxacin
• C. Escitalopram
• D. Magnesium supplements

Correct answer: A

Rationale: The correct answer is A: Potassium supplements. Lisinopril, an ACE inhibitor, can increase potassium levels in the body. Therefore, the nurse should instruct the client to avoid potassium supplements to prevent hyperkalemia, a potentially dangerous condition. Choices B, C, and D are incorrect because they do not have significant interactions with lisinopril that would lead to adverse effects like hyperkalemia.

3. A nurse is caring for a client with a new prescription for metoprolol. Which of the following should the nurse monitor?

• A. Blood pressure
• B. Liver function
• C. Serum potassium levels
• D. Blood glucose

Correct answer: A

Rationale: Corrected Rationale: Metoprolol is a beta-blocker commonly used to treat conditions like hypertension and angina. As a beta-blocker, it primarily affects the cardiovascular system by reducing heart rate and blood pressure. Therefore, the nurse should monitor the client's blood pressure regularly to assess the drug's effectiveness and ensure that it is within the therapeutic range. Monitoring liver function, serum potassium levels, or blood glucose is not typically required for clients taking metoprolol, as its primary impact is on the heart and blood vessels, making choice A the most appropriate monitoring parameter.

4. A client with a new diagnosis of heart failure is prescribed furosemide. Which of the following instructions should the nurse include?

• A. Take the medication in the morning.
• B. Increase intake of potassium-rich foods.
• C. Report a decrease in urine output.
• D. Expect swelling in the lower extremities.

Correct answer: B

Rationale: The correct answer is to instruct the client to increase their intake of potassium-rich foods. Furosemide, a loop diuretic, can lead to potassium loss, which may cause hypokalemia. Increasing potassium intake can help prevent this electrolyte imbalance. Choice A is incorrect because furosemide is usually taken in the morning to prevent sleep disturbances due to increased urination. Choice C is incorrect because a decrease in urine output could indicate a problem and should be reported immediately. Choice D is incorrect because furosemide is used to reduce swelling in the body, including the lower extremities, so expecting swelling is not appropriate.

5. A nurse is providing discharge instructions about breast engorgement to a client who has decided not to breastfeed. Which of the following statements by the client indicates a need for further instruction?

• A. I can wear a supportive bra
• B. I will apply cold compresses to my breasts
• C. I will manually express breast milk
• D. I can take a mild analgesic

Correct answer: C

Rationale: The correct answer is C. Manually expressing breast milk will stimulate more milk production, which contradicts the goal of reducing milk supply in clients who choose not to breastfeed. Choices A, B, and D are correct statements that can help relieve breast engorgement without promoting further milk production.
