Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones. It works by inhibiting the enzyme responsible for the synthesis of thyroid hormones, thereby reducing their levels in the body. This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

Correct Answer: D

Rationale: When a patient with depression is prescribed fluoxetine, the nurse should be vigilant for the potential side effect of increased risk of suicidal thoughts. Fluoxetine, like other antidepressants, may elevate the risk of suicidal thoughts, particularly during the initial phases of treatment. Monitoring the patient for any indications of heightened depression or suicidal ideation is crucial to ensure appropriate interventions are implemented promptly.

Correct Answer: B

Rationale: The most important instruction for the nurse to provide to a patient prescribed a fentanyl patch is to change the patch every 72 hours. This ensures consistent pain control and prevents complications. It is crucial to rotate the application sites to prevent skin irritation or reactions. Using additional heating pads over the patch should be avoided as it can increase the absorption of the medication, leading to overdose or adverse effects. Removing the patch before showering is not necessary as long as the patch is securely in place.

Correct Answer: C

Rationale: The international normalized ratio (INR) is the appropriate parameter to monitor the effectiveness of enoxaparin in preventing clot formation in patients with deep vein thrombosis (DVT). INR reflects the clotting ability of the blood and is commonly used to assess the therapeutic range of anticoagulant medications, such as enoxaparin, which is crucial in managing and preventing thrombotic events like DVT.

Correct Answer: C

Rationale: When a patient is prescribed morphine sulfate, the most critical side effect for the nurse to monitor is respiratory depression. Morphine can suppress the respiratory drive, leading to inadequate ventilation and potentially life-threatening consequences. Monitoring the patient's respiratory status closely is essential to promptly identify and manage any signs of respiratory depression.
