Nursing Elites

1. When teaching a client about managing hypertension, what dietary advice should be emphasized?

• A. Reduce sodium intake
• B. Increase potassium intake
• C. Limit alcohol consumption
• D. All of the above

Correct answer: D

Rationale: When managing hypertension, it is crucial to adopt comprehensive dietary changes. This includes reducing sodium intake to help lower blood pressure, increasing potassium intake to counteract the effects of sodium and help regulate blood pressure, and limiting alcohol consumption as excessive alcohol can raise blood pressure. Therefore, emphasizing all the options provided (A, B, and C) is essential in effectively managing hypertension and reducing overall cardiovascular risk. Choices A, B, and C are not individually sufficient as a single dietary modification but collectively work together to support blood pressure management.

2. The nurse is changing the colostomy bag for a client who is complaining of leakage of diarrheal stool under the disposable ostomy bag. What action should the nurse implement to prevent leakage?

• A. Place a 4x4 wick in the stoma opening
• B. Apply a layer of zinc oxide ointment to the perimeter of the stoma
• C. Cut the bag opening to the measurement of the stoma size
• D. Administer a PRN antidiarrheal agent

Correct answer: C

Rationale: To prevent leakage of stool under the disposable ostomy bag, the nurse should cut the bag opening to the measurement of the stoma size. This action ensures a proper fit, which is crucial in preventing leaks that can lead to skin irritation and compromise stoma care. Placing a 4x4 wick in the stoma opening or applying zinc oxide ointment may not address the issue of leakage effectively. Administering a PRN antidiarrheal agent is not directly related to preventing leakage caused by an ill-fitting ostomy bag.

3. The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?

• A. Deltoid muscle
• B. Inner forearm
• C. Abdomen
• D. Thigh

Correct answer: B

Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.

4. A client is scheduled for an abdominal ultrasound in the morning and has been instructed to fast overnight. The client asks the nurse why fasting is necessary. What is the best response?

• A. It helps reduce the production of intestinal gases.
• B. It ensures clearer imaging by emptying the stomach.
• C. It prevents the risk of aspiration during the procedure.
• D. It is a standard procedure for all surgical interventions.

Correct answer: B

Rationale: The correct answer is B: 'It ensures clearer imaging by emptying the stomach.' Fasting before an abdominal ultrasound is essential to empty the stomach, allowing for better visualization of the abdominal organs. This improves the quality of the imaging and enhances diagnostic accuracy. Choices A, C, and D are incorrect because reducing intestinal gases, preventing aspiration, and being a standard procedure for surgical interventions are not the primary reasons for fasting before an abdominal ultrasound.

5. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.
