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.

Rationale: Propylthiouracil (PTU) is a medication used to treat hyperthyroidism by suppressing the production of thyroid hormones.

This helps to alleviate the symptoms of hyperthyroidism and restore thyroid hormone levels to normal range.

Rationale: Cushing's syndrome is characterized by central-type obesity with thin extremities, often referred to as 'truncal obesity.' This pattern of weight distribution is a key feature of Cushing's syndrome due to excessive cortisol levels, leading to fat accumulation in the face, neck, and abdomen, while the extremities remain relatively thin. The other options listed, such as husky voice, hoarseness, warm, soft, moist, salmon-colored skin, and visible swelling of the neck, are not typical findings associated with Cushing's syndrome.

Correct Answer: B

Rationale: The correct answer is B: Weight gain. Olanzapine, an atypical antipsychotic, is known to cause significant weight gain and metabolic syndrome. It is crucial for healthcare providers to closely monitor patients for these side effects to prevent complications and provide appropriate interventions.
