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 B

Explanation

Choice A rationale
While it is true that the ointment can help prevent certain types of infections, it is not specifically intended to prevent herpes infection. Herpes is a viral infection, and the ointment is an antibiotic, which is used to prevent bacterial infections.
Choice B rationale
The primary purpose of eye ointment is to protect newborns from serious eye infections caused by common bacteria. Mothers who have a sexually transmitted infection (STI) can pass it to their newborns during childbirth, putting them at risk for an eye infection known as ophthalmia neonatorum (ON)3.
Choice C rationale
The ointment does not serve to clear the infant’s vision. It is applied to the eyes to prevent bacterial infections, not to improve or alter the infant’s vision.
Choice D rationale
The ointment is not used to dilate the pupil to visualize the red reflex. The red reflex is a reflection from the lining of the eye that is often observed when looking at the pupil, but this is not related to the application of the ointment.

A. Uses gestures with 1 to 2 word sentences. B. Uses 1 word sentences. C. Speaks in simple sentences with four or more words. D. Recognizes most letters and numbers. E. Recognizes most letters and numbers.

Correct Answer is C

Explanation

Choice A rationale

While using gestures with 1 to 2 word sentences is a developmental milestone, it is typically seen in younger children, around the age of 212.

Choice B rationale

Using 1 word sentences is a developmental milestone usually achieved by children around the age of 112. By the age of 3, children are typically able to speak in simple sentences with four or more words.

Choice C rationale

Speaking in simple sentences with four or more words is a typical developmental milestone for a 3-year-old child. They are able to express their thoughts more clearly and engage in conversations.

Choice D rationale

Recognizing most letters and numbers is a skill that is typically developed around the age of 4 or 512. Therefore, expecting a 3-year-old child to recognize most letters and numbers might be too advanced for their developmental stage.
