Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.

Correct Answer: A

Rationale: The correct answer is A: Miosis, partial eyelid ptosis, and anhidrosis on the affected side of the face. This is indicative of Horner's syndrome, which occurs due to the disruption of sympathetic nerve supply. Miosis (constricted pupil), ptosis (drooping eyelid), and anhidrosis (lack of sweating) are classic signs of Horner's syndrome. These symptoms occur when the tumor invades the ribs and affects the sympathetic nerve ganglia. Summary of other choices: B: Chest pain, dyspnea, cough, weight loss, and fever are more commonly associated with lung cancer but not specific to Horner's syndrome. C: Arm and shoulder pain and atrophy of arm and hand muscles are not typical signs of Horner's syndrome. D: Hoarseness and dysphagia are more common symptoms of compression of the recurrent laryngeal nerve, not Horner's syndrome.

Correct Answer: A

Rationale: The correct answer is A: Include potassium-rich foods. Diuretics can cause potassium loss, leading to hypokalemia. Including potassium-rich foods helps prevent this deficiency. Choice B is incorrect because fruits and fruit juices are often good sources of potassium. Choice C is incorrect as protein-rich foods do not specifically address potassium needs. Choice D is incorrect as dairy products are also good sources of potassium. Therefore, recommending potassium-rich foods is essential to prevent hypokalemia in clients taking diuretics.

Correct Answer: A

Rationale: The correct answer is A: 11mEq/L. In renal failure, the kidneys are unable to excrete excess magnesium, leading to hypermagnesemia. The patient's symptoms of stomach distress and ingesting antacids suggest magnesium intake. A Mg level of 11mEq/L aligns with symptoms like flushed face and weakness. Choices B, C, and D are too low for hypermagnesemia symptoms and would not explain the patient's presentation.

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.
