A healthcare professional is reviewing a client's medications. They include cimetidine and imipramine. Knowing that cimetidine decreases the metabolism of imipramine, the healthcare professional should identify that this combination is likely to result in which of the following effects?
- A. Decreased therapeutic effects of cimetidine
- B. Increased risk of imipramine toxicity
- C. Decreased risk of adverse effects of cimetidine
- D. Increased therapeutic effects of imipramine
Correct Answer: B
Rationale: When cimetidine decreases the metabolism of imipramine, it leads to an increased concentration of imipramine in the body, which can result in imipramine toxicity. This increased risk of toxicity is the likely effect of this drug interaction. Choice A is incorrect because cimetidine's effect on imipramine metabolism does not impact the therapeutic effects of cimetidine. Choice C is incorrect because the interaction does not decrease the risk of adverse effects of cimetidine. Choice D is incorrect as the increased concentration of imipramine can lead to toxicity, not increased therapeutic effects.

A nurse is caring for a group of clients. Which of the following actions should the nurse take to prevent the spread of infection?
- A. Carry a client's soiled linens out of the room in a mesh linen bag
- B. Place a client who has tuberculosis in a room with negative-pressure airflow
- C. Provide disposable plates and utensils for a client who is HIV-positive
- D. Dispose of a client's blood-saturated dressing in a biohazard bag
Correct Answer: B
Rationale: A client who has tuberculosis requires airborne precautions, including placing the client in a room with negative-pressure airflow to reduce the risk of infection transmission. Choices A, C, and D are incorrect. Carrying soiled linens in a mesh bag, providing disposable plates and utensils for an HIV-positive client, and disposing of blood-saturated dressing in a biohazard bag do not specifically address preventing the spread of tuberculosis, which requires airborne precautions.
A client has acute renal failure. Which of the following assessments provides the most accurate measure of the client's fluid status?
- A. Daily weight
- B. Intake and output
- C. Urine specific gravity
- D. Peripheral edema
Correct Answer: A
Rationale: Daily weight is the most accurate measure of fluid status in a client with acute renal failure. Fluctuations in weight reflect changes in body fluid volume, including both fluid retention or loss. Intake and output, while important, may not always accurately reflect overall fluid status as it does not account for insensible losses. Urine specific gravity can provide information on urine concentration but does not offer a comprehensive assessment of overall fluid status. Peripheral edema, although a sign of fluid retention, is a more subjective assessment and may not always accurately reflect the client's fluid status like daily weight monitoring does.
In planning care for a premature infant with respiratory distress syndrome, nursing actions are based on the fact that the most likely cause of this problem stems from the infant's inability to
- A. Stabilize alveolar surface tension
- B. Maintain alveolar surface tension
- C. Promote normal pulmonary blood flow
- D. Regulate intra-cardiac pressure
Correct Answer: B
Rationale: The correct answer is B: Maintain alveolar surface tension. Respiratory distress syndrome in premature infants is often caused by a deficiency in surfactant, a substance that helps maintain alveolar surface tension. Without adequate surfactant, the alveoli collapse, making it difficult for the infant to oxygenate effectively. Choices A, C, and D are incorrect because stabilizing alveolar surface tension is not the issue, promoting normal pulmonary blood flow and regulating intra-cardiac pressure are not directly related to the pathophysiology of respiratory distress syndrome in premature infants.
A client is being taught about dietary management of hypercholesterolemia. Which of the following foods should be suggested to add to the diet?
- A. Avocados
- B. Fried chicken
- C. Whole milk
- D. Bacon
Correct Answer: A
Rationale: Avocados are a good choice to suggest adding to the diet of a client with hypercholesterolemia because they are high in healthy fats, particularly monounsaturated fats, which can help manage cholesterol levels. On the other hand, fried chicken, whole milk, and bacon are high in saturated fats and cholesterol, which should be limited in a diet aimed at managing hypercholesterolemia. Therefore, choices B, C, and D are incorrect.
A client has a new diagnosis of hypothyroidism. Which of the following interventions should the nurse include in the plan of care?
- A. Provide a high-calorie diet.
- B. Encourage frequent rest periods.
- C. Restrict fluid intake.
- D. Increase iodine intake.
Correct Answer: B
Rationale: The correct intervention for a client with hypothyroidism is to encourage frequent rest periods. Hypothyroidism often leads to fatigue, making rest essential for recovery and symptom management. Providing a high-calorie diet is not necessary unless the client has gained weight due to hypothyroidism. Restricting fluid intake is not indicated unless there are specific medical reasons for it. Increasing iodine intake is not recommended for primary hypothyroidism, as it is typically caused by autoimmune thyroiditis or other factors rather than iodine deficiency.
