Nursing Elites

1. A client with atrial fibrillation is prescribed warfarin. What is the most important instruction the nurse should give?

• A. Take the medication with aspirin to improve effectiveness.
• B. Increase intake of green leafy vegetables to support the medication.
• C. Avoid foods high in potassium to reduce bleeding risk.
• D. Avoid alcohol and over-the-counter medications without consulting the provider.

Correct answer: D

Rationale: The correct answer is D. Clients taking warfarin should avoid alcohol and over-the-counter medications without consulting their healthcare provider, as these can interact with warfarin and increase the risk of bleeding. Aspirin, in particular, can exacerbate this risk. Choice A is incorrect because taking warfarin with aspirin can increase the risk of bleeding. Choice B is incorrect as while green leafy vegetables contain vitamin K which can interact with warfarin, it is more important to maintain a consistent intake rather than increase it. Choice C is incorrect because foods high in potassium do not directly impact the bleeding risk associated with warfarin.

2. A toddler presenting with a history of intermittent skin rashes, hives, abdominal pain, and vomiting that occurs after ingesting milk products arrives at the clinic accompanied by the parents. Which type of testing should the nurse educate the toddler's family about?

• A. Complete blood count
• B. Lactose tolerance test
• C. Skin allergy testing
• D. Serum immunoglobulin E

Correct answer: D

Rationale: The correct answer is D, Serum immunoglobulin E (IgE) testing. This test can help diagnose food allergies, including milk protein allergies, in toddlers presenting with symptoms like skin rashes, hives, abdominal pain, and vomiting after consuming milk products. Skin allergy testing is used for allergies but may not be suitable for this age group due to developmental factors. Lactose intolerance, which is different from a milk allergy, is assessed through a lactose tolerance test, not IgE testing. A complete blood count (CBC) would not provide specific information related to food allergies.

3. When taking a health history, which information collected by the nurse correlates most directly to a diagnosis of chronic peripheral arterial insufficiency?

• A. Reports of leg cramping at rest
• B. Family history of heart disease
• C. Current use of beta-blockers
• D. History of intermittent claudication

Correct answer: D

Rationale: Corrected Rationale: Intermittent claudication, or pain in the legs while walking that is relieved by rest, is a classic symptom of peripheral arterial insufficiency. Other factors such as a family history or medication use may contribute to cardiovascular health, but claudication is the most specific indicator. Leg cramping at rest is more indicative of conditions like peripheral neuropathy or deep vein thrombosis. Family history of heart disease and current use of beta-blockers are relevant to overall cardiovascular health, but they are not as directly related to chronic peripheral arterial insufficiency as intermittent claudication.

4. A client with chronic renal failure has a potassium level of 6.5 mEq/L. What is the nurse's priority action?

• A. Administer a potassium supplement.
• B. Notify the healthcare provider immediately.
• C. Administer calcium gluconate.
• D. Restrict the client's potassium intake.

Correct answer: B

Rationale: A potassium level of 6.5 mEq/L indicates hyperkalemia, which can lead to life-threatening arrhythmias. The correct priority action for the nurse is to notify the healthcare provider immediately. Hyperkalemia requires prompt intervention to lower potassium levels and prevent complications. Administering a potassium supplement (Choice A) would worsen the condition. Administering calcium gluconate (Choice C) is a treatment option but is not the nurse's priority action. Restricting the client's potassium intake (Choice D) may be necessary but is not the immediate priority when facing a critical potassium level.

5. A client in heart failure (HF) presents with weakness and poor urine output. Which assessment finding requires immediate action?

• A. Heart rate of 122 bpm and respiratory rate of 28.
• B. Yellow sputum expectorated.
• C. Temperature of 100.5°F (38.1°C).
• D. Shortness of breath on exertion.

Correct answer: C

Rationale: An elevated temperature may indicate infection and should be treated immediately in a client with heart failure.
