Correct Answer: C

Rationale: Oral surgery is a stressful event requiring increased glucocorticoid supplementation to prevent adrenal crisis.

Correct Answer: B

Rationale: A significant drop in blood pressure post-femoral-popliteal bypass graft suggests possible hypoperfusion or graft occlusion. Assessing pedal pulses first is critical to ensure the graft is patent and blood flow is restored to the lower extremity. Compromised pulses could indicate graft failure, requiring immediate intervention. IV fluid rate, nasal cannula flow rate, and capillary refill are secondary considerations after confirming vascular patency.

Correct Answer: C

Rationale: Water increases urine volume, reducing stone formation risk.

Correct Answer: B

Rationale:
Tolerance to opioids is the most likely explanation, as the body adapts to the medication over time, reducing its effectiveness and requiring a dose adjustment.

Correct Answer: A

Rationale: Atropine is contraindicated in glaucoma (increases intraocular pressure), urine retention (worsens retention), and bowel obstruction (reduces motility). It is not contraindicated in diabetes, as it has no direct effect on glucose metabolism.
