A child weighing 18 pounds has been prescribed amoxicillin at a dosage of 25 mg/kg/day. The medication is to be administered orally in two divided doses every 12 hours.

The label on the bottle reads, “Amoxicillin for Oral Suspension, USP 400 mg per 5 mL.”. How many mL should the nurse administer for each dose? (Provide a numerical value only.

If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

Step 1: First, convert the child’s weight from pounds to kilograms. Since 1 pound is approximately 0.45 kilograms, an 18-pound child weighs about 8.16 kilograms (18 pounds × 0.45 kg/pound).

Step 2: Next, calculate the total daily dosage of amoxicillin. The prescribed dosage is 25 mg/kg/day. Therefore, the total daily dosage is 204 mg/day (8.16 kg × 25 mg/kg).

Step 3: Since the medication is to be administered in two divided doses every 12 hours, each dose should be half of the total daily dosage. Therefore, each dose is 102 mg (204 mg/day ÷ 2).

Step 4: Finally, calculate the volume of the suspension to be administered for each dose. The label on the bottle reads, “Amoxicillin for Oral Suspension, USP 400 mg per 5 mL.”. Therefore, each milliliter of the suspension contains 80 mg of amoxicillin (400 mg/5 mL). To administer a dose of 102 mg, the nurse should administer approximately 1.275 mL (102 mg ÷ 80 mg/mL). If rounding is required, round to the nearest tenth.

Therefore, the nurse should administer 1.3 mL for each dose.

Correct Answer is A

Explanation

Choice A rationale
In an infant with aortic stenosis and bilateral fine crackles in both lung fields, hypotension and tachycardia are additional findings that the nurse should expect to observe. Aortic stenosis can lead to decreased cardiac output, which can result in hypotension. The body compensates for this by increasing the heart rate, leading to tachycardia.
Choice B rationale
Vigorous feeding and satiation are not typically associated with aortic stenosis. Infants with aortic stenosis may actually have difficulty feeding due to fatigue.
Choice C rationale
Fever is not a typical symptom of aortic stenosis. If an infant with aortic stenosis has a fever, it may indicate a concurrent infection.
Choice D rationale
Hemiplegia, or paralysis of one side of the body, is not a typical symptom of aortic stenosis. If an infant with aortic stenosis presents with hemiplegia, it may indicate a serious complication such as a stroke.

A. Seeing spots B. Profuse perspiration C. Racing pulse D. Excessive thirst

Correct Answer is B

Explanation

Choice A rationale
Seeing spots is not a typical symptom of low blood sugar (hypoglycemia), which is a common concern for individuals with Type 1 diabetes. Seeing spots could be related to other health issues, such as eye conditions or neurological problems.
Choice B rationale
Profuse perspiration is a common symptom of hypoglycemia. When blood sugar levels drop, the body produces excess adrenaline, leading to sweating. Consuming a source of sugar would help to raise blood sugar levels and alleviate this symptom.
Choice C rationale
A racing pulse is not a specific symptom of hypoglycemia. It could be related to various conditions, including anxiety, dehydration, or heart conditions.
Choice D rationale
Excessive thirst is typically a symptom of high blood sugar (hyperglycemia), not low blood sugar. Consuming sugar when blood sugar levels are already high could potentially worsen the condition.
