A child who weighs 55 pounds receives a prescription for isoniazid 10 mg/kg/day by mouth (PO) once a day.

The bottle is labeled, “Isoniazid Oral Solution, USP 50 mg per 5 mL.”. How many mL should the nurse administer? . .

Answer and Explanation

The Correct Answer is ["25"]

Answer and explanation

Step 1 is to convert the child’s weight from pounds to kilograms since the dosage is prescribed in mg/kg. We know that 1 kg is approximately 2.2 lbs. So, the child’s weight in kg is 55 lbs ÷ 2.2 = 25 kg (rounded to the nearest whole number for simplicity).

Step 2 is to calculate the total daily dosage. The prescription is for isoniazid 10 mg/kg/day. So, the total daily dosage in mg is 10 mg/kg/day × 25 kg = 250 mg/day.

Step 3 is to calculate the volume of the oral solution to administer. The bottle is labeled, “Isoniazid Oral Solution, USP 50 mg per 5 mL.”. So, the volume in mL to administer is (250 mg/day ÷ 50 mg) × 5 mL = 25 mL. Therefore, the nurse should administer 25 mL of the Isoniazid Oral Solution, USP 50 mg per 5 mL, once a day.

Correct Answer is A

Explanation

Choice A rationale

Disseminated intravascular coagulation (DIC) is a serious complication that can occur after severe postpartum hemorrhage. It involves an abnormal activation of the clotting cascade, leading to the formation of small blood clots in the vessels and can result in organ damage.

Choice B rationale

Postpartum psychosis is a rare psychiatric emergency that typically presents with delirium and mood disturbances, and it is not directly related to postpartum hemorrhage.

Choice C rationale

While hard, painful uterine afterpains can occur after childbirth, they are not the highest priority for assessment in a client who experienced a severe postpartum hemorrhage.

Choice D rationale

Placenta accreta is a condition where the placenta attaches too deeply into the uterine wall. However, it is typically identified during pregnancy or at the time of delivery, not after a postpartum hemorrhage.

A. Flaring of the nares. B. Bilateral bronchial breath sounds. C. Diaphragmatic respirations. D. Resting respiratory rate of 35 breaths/minute. E. Resting respiratory rate of 35 breaths/minute.

Correct Answer is A

Explanation

Flaring of the nares is a sign of respiratory distress in children. It indicates that the child is working harder to breathe.
Choice B rationale
Bilateral bronchial breath sounds are normal and do not indicate acute respiratory distress.
Choice C rationale
Diaphragmatic respirations are normal in children and do not indicate acute respiratory distress.
Choice D rationale
A resting respiratory rate of 35 breaths/minute is within the normal range for a preschoolaged child and does not indicate acute respiratory distress.
