You are the nurse caring for an infant with an order to receive Amoxicillin (Amoxil) orally every 6 hours. The safe medication dose is 50mg/kg/day in divided doses. The infant weighs 6 kgs. How much medication will you administer to the infant each dose?

Answer and Explanation

The Correct Answer is ["75"]

The safe dose for the infant is 50 mg/kg/day.

The infant weighs 6 kg.

Calculate the total daily dose:

50mg/kg/day×6kg=300mg/day

Since the medication is to be given every 6 hours, it will be administered 4 times a day (24 hours / 6 hours = 4 doses/day).

Calculate the dose per administration:

300mg/day÷4=75mg/dose

Each dose of Amoxicillin should be 75 mg.

Correct Answer is B

Explanation

A. Hypoplastic heart syndrome: Characterized by underdevelopment of the left side of the heart, not mixing of blood.
B. Atrioventricular canal defect: An atrioventricular canal defect allows oxygenated and deoxygenated blood to mix due to the presence of a common atrioventricular valve and defects in the atrial and ventricular septa. This defect results in a mixture of oxygenated and deoxygenated blood, which can cause varying levels of oxygenation in the blood delivered to the body.
C. Tetralogy of Fallot: Involves a ventricular septal defect leading to right-to-left shunting, but not a direct mixing of oxygenated and deoxygenated blood.
D. Coarctation of the aorta: Involves narrowing of the aorta, not mixing of oxygenated and deoxygenated blood.

A. Circumoral cyanosis B. Tachycardia C. Elevated diastolic blood pressure D. Bradycardia E. Bounding peripheral pulses F. Continuous murmur G. Narrow pulse pressure

Correct Answer is ["B","E","F"]

Explanation

A. Circumoral cyanosis. This can occur but is less specific for PDA and more related to general issues with oxygenation.
B. Tachycardia. PDA can lead to increased heart rate as the heart works harder to manage the increased blood flow.
C. Elevated diastolic blood pressure. PDA usually causes a decrease in diastolic pressure, not an increase.
D. Bradycardia. Bradycardia is not typically associated with PDA.
E. Bounding peripheral pulses. PDA allows more blood to flow into the systemic circulation, leading to stronger pulses.
F. Continuous murmur. PDA typically causes a continuous "machine-like" murmur because of the continuous flow of blood from the aorta to the pulmonary artery.
G. Narrow pulse pressure. PDA often causes a wide pulse pressure, not a narrow one.
