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. 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.

3. A client has altered renal function and is being treated at home. The nurse recognizes that the most accurate indicator of fluid balance during the weekly visits is?

• A. Difference in the intake and output
• B. Changes in the mucous membranes
• C. Skin turgor
• D. Weekly weight

Correct answer: D

Rationale: In clients with altered renal function being treated at home, weekly weight is the most accurate indicator of fluid balance. Fluid retention or loss can significantly affect weight, making it a reliable measure. Choices A, B, and C are not as accurate indicators of fluid balance as weekly weight. Intake and output differences can vary in accuracy and may not capture all aspects of fluid balance. Changes in mucous membranes and skin turgor can be influenced by factors other than fluid balance, making them less precise indicators.

4. What is the expected outcome of prescribing a proton pump inhibitor to a client with a peptic ulcer?

• A. Promote healing of the gastric mucosa.
• B. Neutralize the effects of stomach acid.
• C. Inhibit the growth of Helicobacter pylori.
• D. Reduce gastric acid secretion.

Correct answer: D

Rationale: The correct answer is D: Reduce gastric acid secretion. Proton pump inhibitors (PPIs) work by reducing gastric acid secretion, which helps prevent further irritation of the gastric mucosa and allows ulcers to heal. While promoting healing of the gastric mucosa (Choice A) is an indirect outcome of reducing gastric acid secretion, the primary mechanism of PPIs is to lower acid levels. Choice B, neutralizing the effects of stomach acid, is typically associated with antacids, not PPIs. Inhibiting the growth of Helicobacter pylori (Choice C) is usually achieved with antibiotics, not PPIs.

5. A client is receiving a blood transfusion and develops a fever. What is the nurse's first action?

• A. Administer an antipyretic as prescribed.
• B. Stop the transfusion and notify the healthcare provider.
• C. Slow the rate of the transfusion.
• D. Continue the transfusion and reassess in 15 minutes.

Correct answer: B

Rationale: The correct first action when a client receiving a blood transfusion develops a fever is to stop the transfusion and notify the healthcare provider. This is crucial to prevent further reactions and ensure prompt intervention. Administering an antipyretic (Choice A) may mask symptoms and delay appropriate treatment. Slowing the rate of the transfusion (Choice C) might not address the underlying cause of the fever. Continuing the transfusion and reassessing in 15 minutes (Choice D) could worsen the client's condition if there is a severe reaction occurring.
