A nurse is preparing to administer cephalexin 50 mg/kg/day in divided doses every 8 hours to a child who weighs 33 lb. The amount available is cephalexin oral suspension 250 mg/5 mL.

How many mL should the nurse administer per dose?

(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.) .

Choice A rationale

Wooden building blocks are appropriate for infants with pneumonia as they are safe, can be easily sanitized, and allow the child to engage in quiet play without exerting too much physical energy.

Choice B rationale

Alphabet flash cards are not suitable for an infant, as they are geared towards older children who are learning letters and words.

Choice C rationale

Colored paper and safety scissors are not appropriate for infants due to the risk of choking on small pieces of paper and the potential danger of using scissors.

Choice D rationale

Stringing beads are not suitable for infants as they pose a choking hazard and require fine motor skills that infants have not yet developed.

Choice A rationale

Tretinoin should be applied to the face after it has been cleaned and dried, but a longer wait time than 5 minutes may be recommended to ensure the skin is completely dry.

Choice B rationale

Using a dime-sized amount might be too little or too much depending on the treatment area. Specific application instructions should be based on professional guidance.

Choice C rationale

Using sunscreen with an SPF of 15 or higher is essential when using tretinoin as it makes the skin more sensitive to sunlight, increasing the risk of sunburn and damage.

Choice D rationale

Tretinoin is generally applied at night because it can make the skin more sensitive to sunlight. Applying it in the morning could lead to increased photosensitivity and risk of skin irritation.
