Correct Answer: B

Rationale: The correct answer is B: Do not stop medication abruptly. Abruptly stopping propranolol can lead to rebound hypertension and potentially life-threatening complications. The nurse should emphasize the importance of gradual tapering under medical supervision to avoid adverse effects.

A: Having potassium levels checked is not directly related to propranolol use for hypertension management.
C: Changes in appetite are not specific to propranolol use and may not be a significant concern compared to abrupt cessation of the medication.
D: Resuming usual daily activities is important but not as crucial as the correct instruction to avoid abrupt discontinuation of propranolol.

Correct Answer: C

Rationale: The correct answer is C because in cases of suspected spinal injury, it is crucial to keep the spine immobilized to prevent further damage. Rolling Mr. Gabatan onto his abdomen helps protect his spine by maintaining alignment. Placing a pad under his head provides support and covering him with any material available helps maintain his body temperature. Moving him without proper spinal precautions (options A, B,
D) could worsen his condition. Seeking additional help is important, but ensuring spinal immobilization comes first. Sitting him up or moving him onto a flat piece of lumber can exacerbate spinal injuries.
Therefore, option C is the most appropriate initial action.

Correct Answer: B

Rationale: The correct answer is B: Blurring of vision. This is typically the first symptom of a cataract because the clouding of the lens causes light to scatter, leading to blurred vision. Dry eyes (
A) and eye pain (
C) are not typically associated with cataracts. Loss of peripheral vision (
D) is more commonly seen in conditions like glaucoma. In summary, blurring of vision is the hallmark symptom of cataracts due to lens clouding, distinguishing it from other eye conditions.

Correct Answer: A

Rationale:
Step-by-step rationale:
1. Acute bronchitis is characterized by inflammation of the bronchial tubes.
2. An initial sign of acute bronchitis is a nonproductive cough due to irritation of the bronchial tubes.
3. Anorexia and labored breathing may occur later as the condition progresses.
4. Gastric ulceration is not typically associated with acute bronchitis.

Therefore, choice A (Nonproductive cough) is the correct answer as it aligns with the characteristic symptom of acute bronchitis, while the other choices are not typically observed in the initial stages of the condition.

Correct Answer: C

Rationale:
Rationale:
1. Transsphenoidal adenohypophysectomy is the surgical removal of the pituitary gland's adenohypophysis.
2. The procedure is used to treat pituitary tumors, which can be benign or malignant, but commonly referred to as pituitary adenomas.
3. Pituitary adenomas may secrete hormones excessively, leading to various endocrine disorders.
4. Hormone replacement therapy is required post-surgery to manage hormonal deficiencies.
5.
Therefore, the correct answer is C (Pituitary carcinoma).
Summary:
A, B, and D are incorrect as they do not involve the pituitary gland, which is the primary target of a transsphenoidal adenohypophysectomy.
