What four further assessments of the leg injury are needed?
Assess range of motion.
Ask Mike to stand to assess if he can bear weight.
Assess skin color of the lower leg.
Assess paresthesia.
Assess pain.
Assess pulses of the lower leg.
Correct Answer : C,D,E,F
Choice A rationale
Assessing the range of motion of a severely injured leg is not appropriate during initial evaluation. Movement can worsen the injury or disrupt stabilizing measures such as splints or dressings.
Choice B rationale
Asking the patient to stand or bear weight risks further injury and is contraindicated in cases of visible deformity or massive bleeding.
Choice C rationale
Evaluating skin color helps identify potential ischemia, vascular compromise, or inadequate perfusion. Pallor or cyanosis can indicate significant circulation issues needing urgent care.
Choice D rationale
Paresthesia (tingling or numbness) reflects nerve function and can reveal nerve damage or compromised blood flow, necessitating thorough evaluation.
Choice E rationale
Pain assessment is crucial for identifying the severity of injury and potential complications such as compartment syndrome. Pain disproportionate to the injury suggests complications.
Choice F rationale
Palpating pulses assesses blood flow, ensuring the presence of distal perfusion. Absent or weak pulses require urgent vascular intervention to prevent tissue necrosis.

Correct Answer is D
Explanation
Choice A rationale
Administering dextrose IVP is inappropriate for hyperglycemia. It elevates blood sugar further, risking complications like hyperosmolar hyperglycemic state. It is used to treat severe hypoglycemia instead.
Choice B rationale
Glucagon stimulates glycogen breakdown into glucose, increasing blood sugar. It is contraindicated in hyperglycemia, as it would aggravate elevated glucose levels. It is a treatment for severe hypoglycemia.
Choice C rationale
Holding insulin allows hyperglycemia to persist, increasing risks of complications like ketoacidosis. Insulin administration is essential to reduce the glucose level safely.
Choice D rationale
Rapid-acting insulin like Humalog reduces hyperglycemia efficiently, bringing preprandial blood glucose closer to the target range of 70-130 mg/dL. Administering 4 units is a reasonable corrective dose based on the blood glucose of 243 mg/dL.
Correct Answer is A
Explanation
Choice A rationale
Appendicitis is the leading cause of emergency abdominal surgeries, accounting for a significant percentage globally. It results from inflammation of the appendix, often due to obstruction by fecalith or lymphoid hyperplasia. This condition progresses to localized infection, abscess formation, and potential rupture, requiring urgent surgical intervention to prevent life-threatening complications.
Choice B rationale
The assertion that appendicitis is not the most common reason for emergency abdominal surgery contradicts epidemiological data. Diseases like cholecystitis or bowel obstructions occur less frequently and often have alternate non-surgical management options. Appendicitis’s acute presentation and high risk of complications necessitate surgery, maintaining its predominance in emergency settings.
