What type of electrolyte imbalance would most likely occur following the administration of three tap water enemas?

Hypokalemia

Hypocalcemia

Hypernatremia

Hyperphosphatemia

Answer and Explanation

The Correct Answer is A

A. Hypokalemia: Tap water enemas can cause excessive fluid shifts, leading to potassium loss via stool and dilutional effects. Multiple enemas can result in hypokalemia (low K⁺), which may cause muscle weakness and cardiac arrhythmias.

B. Hypocalcemia: Tap water enemas do not significantly affect calcium levels.

C. Hypernatremia: Tap water is hypotonic, leading to fluid absorption rather than sodium excess.

D. Hyperphosphatemia: Enemas can cause hypophosphatemia rather than excess phosphate levels.

Explanation

A. Nocturia: Excessive nighttime urination, not decreased urine output.

B. Enuresis: Involuntary urination, commonly bedwetting in children.

C. Anuria: Severe lack of urine output (< 100 mL/24 hrs), which is worse than oliguria.

D. Oliguria: Oliguria is defined as urine output < 400 mL/24 hours. 250 mL in 24 hours qualifies as oliguria.

A. Serum potassium 4.8 mmol/l B. Serum glucose 58 mg/d C. Serum sodium 138 mEq/L D. Calcium level of 100 mg

Correct Answer is B

Explanation

A. Serum potassium 4.8 mmol/L: This is a normal potassium level (3.5–5.0 mmol/L) and indicates successful treatment.

B. Serum glucose 58 mg/dL: IV insulin drives potassium into cells, lowering serum potassium. However, insulin also lowers blood glucose, which can lead to hypoglycemia (glucose <70 mg/dL). Hypoglycemia is the primary adverse effect of IV insulin therapy.

C. Serum sodium 138 mEq/L: This is a normal sodium level (135–145 mEq/L) and not an adverse effect.

D. Calcium level of 100 mg: Calcium is not directly affected by IV insulin therapy.
