Correct Answer: C

Rationale: After a transsphenoidal adenohypophysectomy, hormone replacement therapy is needed due to the removal of the pituitary gland. This surgery is typically done to treat pituitary carcinoma, making choice C the correct answer. Pituitary carcinoma is a type of cancer that affects the pituitary gland. Choices A, B, and D are incorrect because they do not involve the pituitary gland. Esophageal carcinoma affects the esophagus, laryngeal carcinoma affects the larynx, and colorectal carcinoma affects the colon and rectum. Therefore, the correct choice, C, is the only one related to the pituitary gland and the procedure described.

Correct Answer: C

Rationale: The correct answer is C: administer oxygen via face mask. Given Aling Nena's sudden chest heaviness post-surgery, oxygen administration is the priority to ensure adequate oxygenation. This can help rule out potential respiratory issues or hypoxemia, which are common post-operatively. Providing oxygen promptly can prevent further complications such as respiratory distress or cardiac compromise. Documenting the pain characteristics (choice A) can be done after ensuring immediate physiological needs are met. Offering analgesics (choice B) without confirming the underlying cause can mask symptoms and delay appropriate interventions. Informing the physician (choice D) is important but not as urgent as addressing potential respiratory compromise.

Correct Answer: B

Rationale: The correct answer is B because it encourages the patient to reflect on potential causes of their fatigue, leading to a more in-depth exploration of the issue. Option A focuses on stress, not necessarily fatigue. Option C is too specific and may not uncover underlying causes. Option D assumes sleep duration is the only factor contributing to fatigue.

Correct Answer: A

Rationale: The correct answer is A because observing the client's gait while walking can provide valuable information about their physical mobility, balance, coordination, and any potential musculoskeletal issues. This assessment helps the nurse determine if the client requires any assistance, mobility aids, or further evaluation by a healthcare provider. Choices B and C are incorrect as observing gait does not directly provide information on personality or psychosocial status. Choice D is incorrect as gait observation is not specifically related to the rate of recovery from surgery. In summary, observing the client's gait is important for assessing physical mobility and identifying potential issues, making it the most relevant choice in this context.

Correct Answer: C

Rationale: The correct answer is C (30 seconds) because the maximum recommended time for suctioning a patient is typically around 10-15 seconds for each pass. Prolonged suctioning can lead to tissue damage, hypoxia, and increased risk of infection. In this case, given the patient's symptoms and medical history (vomiting, weight loss, dehydration, hypotension), it is crucial to limit suction time to prevent further complications. Choices A, B, and D are incorrect as they exceed the safe duration for suctioning and increase the risk of harm to the patient. Choice D, in particular, is significantly longer than the recommended time and could pose serious risks to the patient's health in this situation.
