1. What are the key differences between systolic and diastolic heart failure?

• A. Systolic: Reduced ejection fraction; Diastolic: Preserved ejection fraction
• B. Systolic: Preserved ejection fraction; Diastolic: Reduced ejection fraction
• C. Systolic: Right-sided heart failure; Diastolic: Left-sided heart failure
• D. Systolic: Pulmonary congestion; Diastolic: Systemic congestion

Correct answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

2. A nurse is preparing to administer a blood transfusion. What is the first action?

• A. Administer the blood through an IV push
• B. Verify the client's blood type before starting the transfusion
• C. Warm the blood to body temperature before administration
• D. Ensure the client eats before starting the transfusion

Correct answer: B

Rationale: The correct first action when preparing to administer a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to prevent transfusion reactions and complications. Option A is incorrect because blood transfusions should not be administered through an IV push due to the risk of rapid infusion and adverse reactions. Option C is incorrect because blood should be transfused at room temperature, not body temperature. Option D is incorrect because it is not necessary for the client to eat before a blood transfusion.

3. A nurse is reviewing the plan of care for a client who is receiving chemotherapy for cancer. Which of the following interventions should the nurse include to prevent infection?

• A. Encourage the client to eat high-protein foods
• B. Encourage the client to drink 2 liters of fluid daily
• C. Instruct the client to use a soft toothbrush
• D. Instruct the client to use a mouthwash containing alcohol

Correct answer: C

Rationale: The correct answer is to instruct the client to use a soft toothbrush. Using a soft toothbrush helps prevent bleeding in clients receiving chemotherapy, who are at risk for mucositis. Encouraging the client to eat high-protein foods (Choice A) is important for overall health but not directly related to preventing infection. Encouraging the client to drink 2 liters of fluid daily (Choice B) is essential for hydration but does not specifically prevent infection. Instructing the client to use a mouthwash containing alcohol (Choice D) is contraindicated as alcohol-containing mouthwashes can cause irritation and dryness in the oral mucosa, increasing the risk of infection.

4. A client has an NG tube that needs to be irrigated every 8 hours. Which solution should the nurse use to maintain fluid and electrolyte balance?

• A. Tap water
• B. Sterile water
• C. 0.9% sodium chloride
• D. 0.45% sodium chloride

Correct answer: C

Rationale: The correct solution to maintain fluid and electrolyte balance during NG tube irrigation is 0.9% sodium chloride. This solution is isotonic and helps prevent electrolyte imbalances. Using tap water or sterile water can lead to electrolyte disturbances due to their hypotonic nature, while 0.45% sodium chloride is hypotonic and may cause further imbalances in the client's electrolyte levels.

5. A client with hypokalemia is commonly expected to present with which of the following findings?

• A. Muscle weakness
• B. Nausea
• C. Tingling sensation
• D. Increased thirst

Correct answer: A

Rationale: The correct answer is A: Muscle weakness. Hypokalemia is characterized by low potassium levels in the blood, which can lead to muscle weakness. This occurs because potassium is essential for proper muscle function, and a deficiency can impair muscle strength. Nausea (choice B) is not a typical finding associated with hypokalemia. Tingling sensation (choice C) is more commonly linked to issues like nerve damage or poor blood circulation, rather than hypokalemia. Increased thirst (choice D) is not a direct symptom of hypokalemia; it is more commonly seen in conditions like diabetes or dehydration.
