The nurse is reviewing recent serum lab results for a postoperative male client who underwent a thyroidectomy two days ago. The client is complaining of new onset abdominal cramping and diarrhea and has developed an irregular heart rate. Which emergency medication should the nurse expect to administer to this client?

Furosemide (Lasix)

Diazepam (Valium)

Calcium gluconate

Calcitonin

Answer and Explanation

The Correct Answer is C

A. Furosemide (Lasix): This is a diuretic used to treat fluid retention and does not address the symptoms related to calcium imbalances.
B. Diazepam (Valium): This is an anxiolytic and does not address the symptoms associated with hypocalcemia following a thyroidectomy.
C. Calcium gluconate: This is the appropriate medication for treating hypocalcemia, which can occur after a thyroidectomy due to potential damage to or removal of parathyroid glands, leading to symptoms such as abdominal cramping and irregular heart rate.
D. Calcitonin: While this hormone helps regulate calcium levels, it is more commonly used to treat hypercalcemia, not hypocalcemia.

Correct Answer is C

Explanation

A. Crush the medication and administer it through the tube: Crushing sustained-release medications can alter their release mechanism, leading to potential overdose or ineffective treatment. Sustained-release formulations should not be crushed.
B. Provide the medication orally for the client to swallow: This option is not appropriate because the client has a gastrostomy tube, and oral administration is not suitable for this route.
C. Ask the healthcare provider to prescribe the medication as an elixir for tube administration: This is the correct approach as it ensures the medication is in a form suitable for administration through the gastrostomy tube without altering its release properties.
D. Dissolve the medication in water and administer it through the tube: Dissolving sustained-release tablets is not recommended as it may compromise the medication's intended release mechanism.

A. Hypernatremia B. Hyperglycemia C. Hypercalcemia D. Hyperkalemia

Correct Answer is B

Explanation

A. Hypernatremia: This condition involves elevated sodium levels, which is not directly addressed by the insulin and dextrose order.
B. Hyperglycemia: While dextrose can exacerbate hyperglycemia, the order of insulin and dextrose is not for managing hyperglycemia but for another purpose.
C. Hypercalcemia: This condition involves elevated calcium levels and is not related to the use of insulin and dextrose.
D. Hyperkalemia: The administration of regular insulin with dextrose is often used to manage hyperkalemia. Insulin helps shift potassium into cells, while dextrose prevents hypoglycemia resulting from the insulin.
