A person diagnosed with Type 1 diabetes experienced an episode of hunger, lightheadedness, tachycardia, pallor, headache, and confusion. What is the most probable cause of these symptoms?
Dawn phenomenon from eating a snack before bedtime
Hypoglycemia caused by increased exercise
Hyperglycemia caused by incorrect insulin administration
Somogyi effect from insulin sensitivity
The Correct Answer is B
Choice A reason: Dawn phenomenon involves morning hyperglycemia, not hunger, tachycardia, or confusion. Hypoglycemia from exercise causes these acute symptoms, so this is incorrect for the described episode in Type 1 diabetes.
Choice B reason: Hypoglycemia, often triggered by increased exercise, causes hunger, lightheadedness, tachycardia, pallor, headache, and confusion due to low blood sugar. This matches the symptoms, making it the correct cause for the patient’s episode.
Choice C reason: Hyperglycemia causes thirst, urination, and fatigue, not tachycardia or confusion. Hypoglycemia from exercise aligns with the acute, neuroglycopenic symptoms described, so this is incorrect for the cause.
Choice D reason: Somogyi effect involves rebound hyperglycemia after nocturnal hypoglycemia, not acute symptoms like hunger and confusion. Exercise-induced hypoglycemia fits the immediate presentation, so this is incorrect for the cause.

Correct Answer is B
Explanation
Choice A reason: Inward-pointing feet, or pigeon-toed appearance, describe intoeing, often due to metatarsus adductus or tibial torsion. Genu varum involves the knees angling outward, causing a bowed leg appearance, not foot positioning, making this an incorrect description.
Choice B reason: Genu varum, or bowlegs, is characterized by knees angling outward, creating a bowed appearance of the legs. This condition, common in toddlers or due to conditions like rickets, matches the described deformity, making this the correct description.
Choice C reason: Knees angling inward, causing a knock-kneed appearance, describes genu valgum, not genu varum. These are opposite deformities, with genu varum involving outward knee angulation, making this an incorrect description of the condition.
Choice D reason: Hyperextension of the knee joint, causing excessive leg straightening, describes genu recurvatum, not genu varum. Genu varum involves lateral knee angulation, not hyperextension, making this an incorrect description of the condition.
Correct Answer is ["B","C","D","E"]
Explanation
Choice A reason: Hydration is a treatment, not a complication. Rhabdomyolysis, hyperkalemia, and AKI are complications of crush injuries, with kidney function monitoring essential. This describes an intervention, not a complication, so it’s incorrect.
Choice B reason: Rhabdomyolysis is likely from severe muscle trauma in a crush injury, releasing myoglobin and electrolytes, risking kidney damage. This matches the patient’s injury, making it a correct complication.
Choice C reason: Electrolyte monitoring, especially potassium, is critical due to hyperkalemia risk from muscle breakdown. This can cause arrhythmias, making it a correct selection for complications.
Choice D reason: Acute kidney injury (AKI) is common in rhabdomyolysis, as myoglobin damages kidneys. Given the crush injury, AKI is likely, making this a correct complication.
Choice E reason: Monitoring kidney function (creatinine, BUN, urine output) detects AKI from rhabdomyolysis. This ensures timely intervention, making it a correct choice for complications.
