A nurse is providing an in-service on the complications of overdosing on morphine, such as the opioid toxicity triad. Which of the following signs and symptoms should the nurse include in her in-service about opioid toxicity triad?
Coma, respiratory alkalosis, and regular pupils.
Pinpoint pupils, respiratory depression, and coma.
Pinpoint pupils, hypertension, and constipation.
Constipation, pupillary dilation, and hypotension.
The Correct Answer is B
A. Coma, respiratory alkalosis, and regular pupils: These are not indicative of opioid toxicity. Opioid toxicity typically leads to respiratory depression and constricted pupils.
B. Pinpoint pupils, respiratory depression, and coma: This is the classic triad of opioid toxicity. Pinpoint pupils, respiratory depression, and coma are hallmark signs.
C. Pinpoint pupils, hypertension, and constipation: Hypertension is not a typical feature of opioid overdose; hypotension is more common.
D. Constipation, pupillary dilation, and hypotension: Constipation is common with opioids but pupillary dilation and hypotension are not part of the typical toxicity triad.

Correct Answer is C
Explanation
A. Calcium carbonate does not treat hypoglycemia. It is used to address low calcium levels, not blood sugar levels.
B. Calcium carbonate is not used to treat hypothyroidism. Hypothyroidism is treated with thyroid hormone replacement therapy (e.g., levothyroxine).
C. Calcium carbonate is commonly used to treat hypocalcemia (low calcium levels in the blood) and to prevent bone loss in conditions such as osteoporosis.
D. Calcium carbonate is not used to treat hyperkalemia (high potassium levels). Treatments for hyperkalemia may include medications like sodium bicarbonate or calcium gluconate, but not calcium carbonate.
Correct Answer is C
Explanation
A. Mannitol is an osmotic diuretic, and although it can cause dehydration and electrolyte imbalances, it does not specifically cause hypokalemia as a primary side effect.
B. Spironolactone is a potassium-sparing diuretic, so it is less likely to cause hypokalemia. In fact, it can cause hyperkalemia.
C. Furosemide is a loop diuretic that increases urine output and can lead to potassium loss, causing hypokalemia. This is a common complication of loop diuretics.
D. Metformin is an oral antidiabetic medication and is not a diuretic, so it is not associated with hypokalemia.
