The patient received Humalog (rapid acting) insulin 5 units subcutaneously at 8:00 AM. The nurse plans to monitor this patient for signs of hypoglycemia at which time related to the insulin's peak action?

1:00 PM

8:00 PM

There is no peak action for this insulin

9:00 AM

Answer and Explanation

The Correct Answer is D

Choice A reason: 1:00 PM is not the correct time to monitor the patient for signs of hypoglycemia related to the insulin's peak action. Humalog is a rapid acting insulin that starts to work within 15 minutes, peaks in about an hour, and lasts for 2 to 4 hours. Therefore, the peak action of Humalog given at 8:00 AM would be around 9:00 AM, not 1:00 PM.

Choice B reason: 8:00 PM is also not the correct time to monitor the patient for signs of hypoglycemia related to the insulin's peak action. As explained in choice A, Humalog peaks in about an hour and lasts for 2 to 4 hours. Therefore, the effect of Humalog given at 8:00 AM would wear off by 12:00 PM, not 8:00 PM.

Choice C reason: There is no peak action for this insulin is an incorrect statement. Humalog does have a peak action, as described in choice A. The peak action of an insulin is the time when the insulin is most effective in lowering the blood glucose level. The peak action of an insulin can vary depending on the type, dose, and individual response of the patient.

Choice D reason: 9:00 AM is the correct time to monitor the patient for signs of hypoglycemia related to the insulin's peak action. Hypoglycemia is a condition of low blood glucose level, which can cause symptoms such as sweating, shaking, hunger, headache, dizziness, confusion, and loss of consciousness. Hypoglycemia can occur when the insulin dose is too high, the food intake is too low, or the physical activity is too high. The nurse should monitor the patient for signs of hypoglycemia around the peak action of the insulin, as this is when the blood glucose level is most likely to drop. The nurse should also teach the patient how to prevent, recognize, and treat hypoglycemia.

Correct Answer is C

Explanation

Choice A reason: 363 is not the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 3.5 kg, not 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 3.5 and 10 kg is 100 mL/kg¹.

Choice B reason: 727 is not the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 10 kg, not 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 10 and 20 kg is 1000 mL plus 50 mL for every kg over 10¹.

Choice C reason: 1300 is the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 10 and 20 kg is 1000 mL plus 50 mL for every kg over 10¹. Therefore, for an infant who weighs 16 kg, the daily maintenance fluid requirement is 1000 mL plus 50 mL times 6, which equals 1300 mL.

Choice D reason: 1600 is not the correct answer. This is the daily maintenance fluid requirement for an infant who weighs 20 kg, not 16 kg. The formula for calculating the daily maintenance fluid requirement for infants who weigh between 10 and 20 kg is 1000 mL plus 50 mL for every kg over 10¹. For infants who weigh more than 20 kg, the formula is 1500 mL plus 20 mL for every kg over 20¹.

A. Administer IV morphine sulfate 4 mg every 2 hours PRN. B. Dextrose 5% in 0.9% sodium chloride, continuous infusion. C. Infuse 5% dextrose in water at 125 mL/hr. D. Neurologic assessment Q2 hours.

Correct Answer is C

Explanation

Choice A reason: This statement is false. IV morphine sulfate is a pain medication that can be given as needed to the postoperative patient. It does not affect the serum sodium level.

Choice B reason: This statement is false. Dextrose 5% in 0.9% sodium chloride is a hypertonic solution that can be used to treat hyponatremia, or low serum sodium level. It provides both glucose and sodium to the patient.

Choice C reason: This statement is true. 5% dextrose in water is a hypotonic solution that can cause further dilution of the serum sodium level. It can worsen the hyponatremia and increase the risk of cerebral edema and seizures.

Choice D reason: This statement is false. Neurologic assessment Q2 hours is a necessary intervention for a patient with hyponatremia, as it can monitor for signs of neurologic deterioration such as confusion, lethargy, or coma.
