Nursing Elites

1. When providing teaching to a client with a new prescription for atorvastatin, which of the following instructions should the nurse include?

• A. Take the medication in the evening.
• B. Take the medication with food.
• C. Increase your intake of grapefruit juice.
• D. Avoid consuming dairy products.

Correct answer: A

Rationale: The correct instruction for a client with a new prescription for atorvastatin is to take the medication in the evening. Atorvastatin is more effective when taken at night because cholesterol synthesis is higher during this time. This timing helps optimize the drug's cholesterol-lowering effects and enhances its overall efficacy in managing lipid levels. Choices B, C, and D are incorrect. Taking atorvastatin with food can decrease its absorption, grapefruit juice can interact with atorvastatin leading to increased side effects, and there is no specific need to avoid dairy products while on atorvastatin unless instructed otherwise by the healthcare provider.

2. The client with a history of heart failure is receiving digoxin (Lanoxin). Which electrolyte imbalance increases the risk of digoxin toxicity?

• A. Hypernatremia
• B. Hypercalcemia
• C. Hypokalemia
• D. Hypomagnesemia

Correct answer: C

Rationale: Hypokalemia increases the risk of digoxin toxicity as low potassium levels enhance the effects of digoxin on the heart, leading to toxicity and potential adverse effects. Hypernatremia (Choice A) is not directly associated with an increased risk of digoxin toxicity. Hypercalcemia (Choice B) does not increase the risk of digoxin toxicity. Hypomagnesemia (Choice D) can contribute to digoxin toxicity, but hypokalemia has a more significant impact on increasing the risk.

3. The healthcare provider is reviewing the medication orders for a client with angina pectoris. Which medication is typically prescribed to prevent angina attacks?

• A. Aspirin
• B. Nitroglycerin
• C. Atenolol
• D. Simvastatin

Correct answer: B

Rationale: Nitroglycerin is the medication typically prescribed to prevent angina attacks. It works by dilating blood vessels, increasing blood flow, and reducing the heart's workload, hence relieving angina symptoms. Aspirin is often used to prevent blood clots, not specifically to prevent angina attacks. Atenolol is a beta-blocker used to manage high blood pressure and chest pain but is not typically prescribed to prevent angina attacks. Simvastatin is a statin medication primarily used to lower cholesterol levels and is not indicated for preventing angina attacks.

4. The healthcare provider assesses a client who has been prescribed furosemide (Lasix) for cardiac disease. Which electrocardiographic change would be a concern for a client taking a diuretic?

• A. Tall, spiked T waves
• B. A prolonged QT interval
• C. A widening QRS complex
• D. Presence of a U wave

Correct answer: D

Rationale: The presence of a U wave is often associated with hypokalemia, a possible side effect of diuretic therapy like furosemide. Hypokalemia can lead to U wave formation on an electrocardiogram, making the presence of U waves a concerning finding in clients taking diuretics. Tall, spiked T waves are typically seen in hyperkalemia, not hypokalemia. A prolonged QT interval is more commonly associated with conditions like Long QT syndrome or certain medications, not specifically with diuretics. A widening QRS complex is usually seen in conditions affecting the conduction system of the heart, such as bundle branch blocks, rather than being directly related to diuretic use.

5. The healthcare professional is assessing a client who presents with jaundice. Which assessment finding is most important for the healthcare professional to follow up on?

• A. Urine specific gravity of 1.03
• B. Frothy, tea-colored urine
• C. Clay-colored stools
• D. Elevated serum amylase and lipase levels

Correct answer: D

Rationale: Elevated serum amylase and lipase levels are indicative of pancreatitis, a serious condition that can manifest with jaundice. Timely follow-up is crucial to manage pancreatitis and its complications effectively in a jaundiced client. Choices A, B, and C are less critical in this scenario. Urine specific gravity within normal range, frothy tea-colored urine, and clay-colored stools can be associated with various conditions but are not directly indicative of pancreatitis, which is the most concerning condition associated with jaundice.
