A nurse is contributing to the plan of care of an unconscious adolescent who ingested a non-corrosive substance that has no recommended antidote. The nurse should recommend performing gastric lavage with which of the following substances?

Choice A rationale
Pediculosis capitis, also known as head lice, is a common condition in children. One of the definitive indications of this condition is the presence of firmly attached white particles on the hair, which are the eggs or “nits” of the lice.
Choice B rationale
While itching and scratching of the head can be a symptom of pediculosis capitis, it is not a definitive indication as it can be caused by other conditions such as dandruff or dermatitis.
Choice C rationale
Patchy areas of hair loss are not typically associated with pediculosis capitis. They could indicate a different condition, such as alopecia areata or tinea capitis.
Choice D rationale
Thick yellow-crusted lesions on a red base are not a symptom of pediculosis capitis. This description is more consistent with impetigo, a bacterial skin infection.

The child weighs 22 lb, which is approximately 10 kg (since 1 kg is approximately 2.2 lb).

The prescribed dose of acetaminophen is 10 mg/kg. Step 1 is: Calculate the total dose of acetaminophen for the child. This is done by multiplying the child’s weight in kg by the prescribed dose in mg/kg. 10 kg×10 mg/kg=100 mg The available acetaminophen liquid is 160 mg/5 mL. Step 2 is: Calculate the volume of acetaminophen liquid to administer. This is done by setting up a proportion with the total dose of acetaminophen and the concentration of the available liquid. x mL100 mg=5 mL160 mg Solving for x gives: x=160 mg mg×5 mL=3.125 mL Therefore, the nurse should administer approximately 3.125 mL of the acetaminophen liquid. .
