1. What are the primary differences between left-sided and right-sided heart failure?

• A. Left-sided: Pulmonary congestion; Right-sided: Systemic edema
• B. Right-sided: Pulmonary congestion; Left-sided: Systemic edema
• C. Left-sided: Systemic edema; Right-sided: Pulmonary congestion
• D. Right-sided: Pulmonary congestion; Left-sided: Heart failure

Correct answer: A

Rationale: The correct answer is A: "Left-sided: Pulmonary congestion; Right-sided: Systemic edema." Left-sided heart failure primarily affects the lungs, leading to pulmonary congestion, which manifests as symptoms like shortness of breath and cough. On the other hand, right-sided heart failure causes systemic congestion and edema, often presenting as swelling in the legs and abdomen due to fluid retention. Choice B is incorrect because it swaps the features of left-sided and right-sided heart failure. Choice C is incorrect as it also incorrectly switches the characteristics of the two types of heart failure. Choice D is incorrect because it inaccurately associates left-sided heart failure with pulmonary congestion and right-sided heart failure with heart failure itself, which is not a distinguishing feature.

2. A nurse is reviewing the medical record of a client who has schizophrenia and is taking clozapine. Which of the following findings should the nurse identify as a contraindication to the administration of clozapine?

• A. WBC count 2,900 /mm3.
• B. Fasting blood glucose 100 mg/dl.
• C. Hgb 14 g/dl.
• D. Heart rate 58/min.

Correct answer: A

Rationale: A WBC count of 2,900/mm3 indicates leukopenia, which is a serious side effect of clozapine and contraindicates its use. Leukopenia is a significant concern with clozapine therapy due to the risk of agranulocytosis, a potentially life-threatening condition. Monitoring the WBC count is crucial to detect this adverse effect early. The other options (B, C, and D) are within normal ranges and not contraindications for administering clozapine.

3. Which of the following interventions should the nurse implement for a client with dementia who is at risk of falling?

• A. Keep the bed in the lowest position
• B. Raise all four side rails to prevent falls
• C. Assist with ambulation every 2 hours
• D. Use a bed exit alarm to notify staff of attempts to leave the bed

Correct answer: D

Rationale: The correct intervention for a client with dementia at risk of falling is to use a bed exit alarm to notify staff of attempts to leave the bed. This intervention helps in preventing falls by alerting the staff when the client tries to get out of bed. Keeping the bed in the lowest position (Choice A) may not prevent falls and could make it challenging for staff to provide care. Raising all four side rails (Choice B) can be a restraint and is not recommended as it may lead to entrapment or other risks. Assisting with ambulation every 2 hours (Choice C) may not be feasible or effective in preventing falls, as the client may attempt to get out of bed at any time.

4. What are the primary causes of respiratory acidosis?

• A. Hypoventilation and lung disease
• B. Hyperventilation and pneumonia
• C. Increased oxygen saturation and tachypnea
• D. Dehydration and hypoxia

Correct answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.

5. A client with hypertension is receiving lifestyle education from a nurse. What should be emphasized?

• A. Encourage a low-sodium diet
• B. Advise the client to avoid caffeinated drinks
• C. Recommend increasing high-protein foods
• D. Advise the client to reduce fat intake

Correct answer: B

Rationale: The correct answer is to advise the client to avoid caffeinated drinks. Caffeine can temporarily increase blood pressure, so avoiding caffeinated drinks can help manage hypertension. Encouraging a low-sodium diet (Choice A) is essential for hypertension management as excess sodium can raise blood pressure. Increasing high-protein foods (Choice C) is not a primary focus in managing hypertension. While reducing fat intake (Choice D) can be beneficial for overall health, it is not the priority in lifestyle modifications for hypertension.
