Correct Answer: B

Rationale: The correct answer is B. Mr. Sy's statement indicates he understands the pre-operative fasting instructions, which is crucial to prevent aspiration during surgery. Not eating after midnight reduces the risk of complications. A: Incorrect. Wearing a pneumatic compression device post-surgery is important, but this statement does not demonstrate understanding of pre-surgery preparations. C: Incorrect. Knowing the skin preparation site size does not indicate understanding of the surgery process. D: Incorrect. Signing the consent form at the operating table may indicate lack of understanding of the consent process and timing. In summary, choice B is correct as it shows Mr. Sy's awareness of the fasting requirement before surgery, which is crucial for a safe operation.

Correct Answer: C

Rationale: The correct answer is C: Introduce variations in styles of clothing. This suggestion promotes the client's self-image by helping her feel more comfortable and confident in her appearance despite the lymphedema. It allows her to express her personal style while accommodating the enlarged arm. A: Placing the arm in a sling does not address the client's self-image concerns and may further highlight the abnormality. B: Applying cold soaks may help with swelling but does not directly address the client's self-image. D: Tying a tight bandage can worsen lymphedema and does not address the client's self-image concerns.

Correct Answer: B

Rationale: The correct answer is B: Clonidine (Catapres). Clonidine is known to cause headache as a side effect due to its mechanism of action affecting blood pressure regulation in the brain. Furosemide (A) is a diuretic that typically causes electrolyte imbalances, not headaches. Atenolol (C) is a beta-blocker used for hypertension, which can cause fatigue but not typically headaches. Adalat (D) is a calcium channel blocker that usually causes peripheral edema, not headaches.

Correct Answer: B

Rationale: The correct answer is B: To provide a means for further comparison and evaluation. By recording the color of drainage from each tube and catheter, the nurse can monitor changes over time, assess for any abnormalities, and evaluate the effectiveness of treatment. This helps in detecting complications early and making informed decisions. Rationale for other choices: A: To restore and maintain intravascular volume - Monitoring drainage color does not directly relate to intravascular volume status. C: To avoid interference with wound drainage - Monitoring drainage color does not prevent interference with wound drainage. D: To prevent pain related to obstruction - Monitoring drainage color does not directly prevent pain related to obstruction.

Correct Answer: C

Rationale: The correct answer is C. Aling Maria is admitted for myxedema, which is severe hypothyroidism. Symptoms of hypothyroidism include lethargy, weight gain, slow speech, and decreased respiratory rate. Bradycardia, weight loss, heart failure, and diarrhea are not typical symptoms of myxedema. Tachycardia, constipation, and exopthalmus are more commonly associated with hyperthyroidism. Hypothermia, weight loss, and increased respiratory rate are not consistent with myxedema. Thus, choice C is the most appropriate initial assessment for Aling Maria.
