A nurse is preparing to administer azithromycin oral suspension 10 mg/kg/day to a 15-month- old infant who has otitis media. The infant weighs 22 Ib. The amount available is azithromycin oral suspension 200 mg/5 mL. How many mL should the nurse plan to 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 ["2.5"]

- Convert the infant's weight from pounds to kilograms: 22 Ib / 2.2 = 10 kg

- Calculate the daily dose of azithromycin: 10 mg/kg/day x 10 kg = 100 mg/day

- Calculate the volume of azithromycin oral suspension needed: 100 mg/day / (200 mg/5 mL) = 2.5 mL/day

- Round the answer to the nearest tenth: 2.5 mL/day

- The nurse should plan to administer 2.5 mL of azithromycin oral suspension to the infant.

Correct Answer is D

Explanation

Choice A reason:

A temperature of 37.7° C (99.9° F) is slightly elevated but not a cause for immediate concern after immunization. It can be a normal response.

Choice B reason:

Redness at the injection site is a common and expected reaction after immunization. It does not require immediate intervention.

Choice C reason:

Prolonged crying can occur after immunization, but it is not a priority over a potential allergic reaction indicated by hives.

Choice D reason:

Hives on the child's neck indicate a potential allergic reaction to the immunization. This is a priority finding and requires immediate attention from the nurse.

A. Wrap the extremity loosely with an elastic bandage. B. Apply warm compresses to the extremity. C. Elevate the extremity above the level of the heart. D. Encourage active range of motion of the extremity.

Correct Answer is C

Explanation

Choice A reason:

Wrapping the extremity loosely with an elastic bandage may provide support but is not specifically aimed at reducing swelling.

Choice B reason:

Applying warm compresses can be beneficial for some types of injuries, but for a sprained wrist, cold compresses are more effective in reducing swelling.

Choice C reason:

This statement is correct. Elevating the extremity above the level of the heart helps to reduce swelling by promoting venous return and reducing blood flow to the affected area.

Choice D reason:

Encouraging active range of motion may be important for rehabilitation, but it is not the initial intervention for minimizing swelling in the first 12 to 24 hours after a sprain.
