A nurse is preparing to administer acetaminophen 10 mg/kg/dose to a child who weighs 28 lb. The amount available is acetaminophen 120 mg/5 mL. How many mL should the nurse administer?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["5.3."]

To calculate the dose of acetaminophen for a child, the nurse needs to convert the child's weight from pounds to kilograms and then multiply it by the prescribed dose per kilogram. The formula is:

Weight in kg = Weight in lb / 2.2
Dose in mg = Weight in kg x Dose per kg
Dose in mL = Dose in mg / Concentration in mg/mL

Using the given information, the nurse can plug in the values and solve for the dose in mL:

Weight in kg = 28 / 2.2 = 12.73
Dose in mg = 12.73 x 10 = 127.3
Dose in mL = 127.3 / 120 x 5 = 5.3

Therefore, the nurse should administer 5.3 mL of acetaminophen to the child.

Correct Answer is A

Explanation

A. Apex of the heart:The apex of the heart is the preferred site for measuring an infant's heart rate. It is located at the 4th or 5th intercostal space, just medial to the midclavicular line, allowing for accurate auscultation of the heartbeat.

B. Carotid artery:While the carotid artery can be used to assess heart rate in older children and adults, it is not ideal for infants due to the risk of compromising circulation to the brain if pressure is applied too forcefully.

C. Brachial artery:The brachial artery is often used to assess pulse in infants, especially in cases of CPR, but it is not the preferred site for routine heart rate measurement. It may be used when assessing circulation or checking for pulses, but auscultation at the apex is more accurate for heart rate.

D. Radial artery:The radial artery can be difficult to palpate in infants due to their small size and is generally not used for heart rate assessment in this age group. The apex is a more reliable location.

A. 13% weight loss B. Bulging anterior fontanel C. Bradypnea D. Capillary refill 3 seconds
