Correct Answer: A

Rationale: The correct answer is A, weight loss. Metformin is commonly associated with weight loss rather than weight gain. Metformin works by decreasing glucose production in the liver and improving insulin sensitivity, which can lead to weight loss in some individuals. Choices B, C, and D are incorrect. Weight gain is not a typical side effect of metformin. Drowsiness and hypertension are also not commonly associated with metformin use.

Correct Answer: B

Rationale: The correct answer is B, Diabetes insipidus. Diabetes insipidus can develop after a head injury due to damage to the hypothalamus or pituitary gland, leading to a deficiency in antidiuretic hormone (ADH). Pheochromocytoma (Choice A) is a tumor of the adrenal gland that causes excessive release of catecholamines, leading to hypertension. Hashimoto's disease (Choice C) is an autoimmune condition affecting the thyroid gland. Gynecomastia (Choice D) refers to the enlargement of breast tissue in males and is not directly related to a closed head injury with increased intracranial pressure.

Correct Answer: D

Rationale: Complaints of chills and feeling feverish may indicate infection, which requires immediate intervention. In this postoperative setting, the presence of thin pink drainage in the Jackson Pratt drain is expected as part of the normal healing process. Guarding when the nurse touches the abdomen and tenderness around the surgical site are common after surgery and may not require immediate intervention unless they are severe or accompanied by other concerning symptoms.

Correct Answer: B

Rationale: The correct answer is B: Writing letters. Writing requires fine motor skills, which are often impaired in a right-handed person with a right-sided CVA. Eating meals (choice A) involves gross motor skills and can be adapted for easier handling. Combing the hair (choice C) and dressing every morning (choice D) also require fine motor skills, but they are generally less complex and demanding than writing letters.

Correct Answer: A

Rationale: The correct answer is A, 'Evaluation.' Evaluation in nursing involves assessing whether the care provided is appropriate and effective in relation to the patient's current physiological and psychological status. This step helps determine the outcomes of the care provided and if any changes are needed. Choice B, 'Planning,' focuses on developing a plan of care based on the assessment findings. Choice C, 'Implementation,' involves carrying out the plan of care. Choice D, 'Assessment,' is the initial step in the nursing process that involves gathering data about the patient's health status.
