Nursing Elites

1. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.

2. 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.

3. A client with a diagnosis of heart failure is receiving furosemide (Lasix). Which electrolyte imbalance should the nurse monitor for?

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

Correct answer: D

Rationale: The correct answer is D: Hypokalemia. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Therefore, the nurse should monitor the client for low potassium levels. Choice A, Hyperkalemia, is incorrect as furosemide does not typically cause high potassium levels. Choice B, Hyponatremia, is incorrect as furosemide primarily affects potassium levels, not sodium. Choice C, Hypocalcemia, is incorrect as furosemide does not directly impact calcium levels.

4. A client with a history of hypertension is prescribed lisinopril. Which potential side effect should the nurse monitor for?

• A. Hypokalemia
• B. Hyperglycemia
• C. Persistent cough
• D. Tachycardia

Correct answer: C

Rationale: The correct answer is C: Persistent cough. Lisinopril is an ACE inhibitor commonly associated with a persistent dry cough as a side effect. This cough is thought to result from increased bradykinin levels. Choices A, B, and D are incorrect. Hypokalemia is not a common side effect of lisinopril; in fact, it may lead to hyperkalemia. Hyperglycemia is not a typical side effect of lisinopril use. Tachycardia is also not a common side effect associated with ACE inhibitors like lisinopril.

5. A client is diagnosed with Angina Pectoris. Which factor in the client's history is likely related to the anginal pain?

• A. Smokes one pack of cigarettes daily
• B. Drinks two beers daily
• C. Works in a job that requires exposure to the sun
• D. Eats while lying in bed

Correct answer: A

Rationale: The correct answer is A: 'Smokes one pack of cigarettes daily.' Smoking is a major risk factor for angina and other cardiovascular diseases due to its impact on blood vessels. Choice B, 'Drinks two beers daily,' is not directly associated with angina pectoris. While excessive alcohol consumption can contribute to heart problems, it is not a primary risk factor for angina. Choice C, 'Works in a job that requires exposure to the sun,' is not typically related to angina pectoris. Sun exposure is more closely linked to skin-related conditions. Choice D, 'Eats while lying in bed,' is also not a common risk factor for angina. While certain eating habits can impact heart health, this specific behavior is not directly associated with angina pectoris.
