Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure.
• B. Assess heart rate.
• C. Monitor respiratory rate.
• D. Measure oxygen saturation.

Correct answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.

3. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.

4. A client is admitted with Atrial Fibrillation and is administered amiodarone (Cordarone). What therapeutic response should the nurse anticipate?

• A. Conversion of irregular heart rate to regular heart rhythm
• B. Pulse oximetry readings within normal range during activity
• C. Peripheral pulse points with adequate capillary refill
• D. Increase in exercise tolerance without shortness of breath

Correct answer: A

Rationale: The correct answer is A: Conversion of irregular heart rate to regular heart rhythm. Amiodarone is a medication commonly used to restore and maintain normal heart rhythm in clients with atrial fibrillation. It works by slowing down the electrical signals in the heart, helping to regulate the heartbeat. Choices B, C, and D are incorrect because they do not directly relate to the therapeutic response expected from administering amiodarone in a client with atrial fibrillation. Pulse oximetry readings, peripheral pulses, capillary refill, and exercise tolerance are important assessments but are not the primary therapeutic goal of using amiodarone in this situation.

5. A client is prescribed warfarin for the prevention of thromboembolism. What dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Maintain a consistent intake of vitamin K-rich foods
• C. Avoid all foods containing vitamin K
• D. Consume a high-protein diet

Correct answer: B

Rationale: The correct answer is B. Maintaining a consistent intake of vitamin K-rich foods is important for patients taking warfarin as it helps keep the effects of the medication stable. Choice A is incorrect because while green leafy vegetables are high in vitamin K, they should not be avoided completely but rather consumed consistently. Choice C is also incorrect as avoiding all foods containing vitamin K can lead to fluctuations in warfarin's effectiveness. Choice D is incorrect as a high-protein diet is not specifically recommended for patients taking warfarin.
