Nursing Elites

1. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.

2. While changing a client's chest tube dressing, the nurse notes a cracking sensation when gentle pressure is applied to the skin at the insertion site. What should the nurse do next?

• A. Apply a pressure dressing at the chest tube site.
• B. Administer an oral antihistamine per PRN order.
• C. Assess the client for allergies to topical cleaning agents.
• D. Measure the area of crackling and swelling.

Correct answer: D

Rationale: Measuring the area of crackling and swelling is essential in monitoring the progression of subcutaneous emphysema, which can result from air leaking into the tissues around the chest tube insertion site. This technique helps evaluate the extent of the issue and guides further interventions. Applying a pressure dressing (choice A) might exacerbate the condition by trapping more air. Administering an oral antihistamine (choice B) is not indicated for subcutaneous emphysema. Assessing for allergies to topical cleaning agents (choice C) is not the priority in this situation compared to evaluating and managing the subcutaneous emphysema.

3. What instruction should the nurse include for a client prescribed nitroglycerin for a myocardial infarction?

• A. Take the medication only when experiencing severe chest pain.
• B. Store the medication in a dark container to protect it from light.
• C. Take the medication before engaging in physical activity that may trigger chest pain.
• D. Limit nitroglycerin use to no more than three doses in 15 minutes.

Correct answer: D

Rationale: The correct answer is D: 'Limit nitroglycerin use to no more than three doses in 15 minutes.' This instruction is crucial to prevent excessive use, which can lead to severe hypotension and other complications. Choice A is incorrect because nitroglycerin should also be used preventatively, not only during severe chest pain. Choice B is irrelevant and not a necessary instruction for nitroglycerin use. Choice C is incorrect as nitroglycerin is typically taken to prevent chest pain rather than waiting for an activity that may trigger it.

4. An older client with a long history of coronary artery disease, HTN, and HF arrives in the ED in respiratory distress. The healthcare provider prescribes furosemide IV. Which therapeutic response to furosemide should the nurse expect in the client with acute HF?

• A. Decreased heart rate
• B. Improved blood pressure
• C. Increased urine output
• D. Reduced preload

Correct answer: D

Rationale: The correct answer is D: Reduced preload. Furosemide is a diuretic that reduces fluid overload in heart failure, which lowers the preload (the volume of blood in the ventricles before contraction). By reducing this volume, furosemide improves symptoms of heart failure. While furosemide may lead to increased urine output and lower blood pressure, these effects are secondary to the reduction in preload. Decreased heart rate is not a direct effect of furosemide in heart failure.

5. A combination multi-drug cocktail is being considered for an asymptomatic HIV-infected client with a CD4 cell count of 500. Which nursing assessment of the client is most crucial in determining whether therapy should be initiated?

• A. Presence of viral symptoms
• B. Engages in high-risk behaviors
• C. Willingness to comply with complex drug schedules
• D. History of opportunistic infections

Correct answer: C

Rationale: The most crucial nursing assessment in determining whether therapy should be initiated for an asymptomatic HIV-infected client with a CD4 cell count of 500 is the client's willingness to comply with complex drug schedules. Adherence to antiretroviral therapy is essential for its effectiveness. Assessing the client's willingness and ability to comply with the complex medication regimen is crucial to ensure successful treatment and prevent drug resistance. Choices A, B, and D, although important in the overall care of the client, are not as crucial as assessing the client's willingness to adhere to the prescribed drug regimen.
