A nurse is contributing to the plan of care for a school-aged child who is scheduled for a biopsy.
Which of the following interventions should the nurse recommend?

Choice A rationale

Lansoprazole is a proton pump inhibitor designed to reduce gastric acid production, enhancing mucosal healing in gastroesophageal reflux disease. Administering the medication 30 minutes before breakfast optimizes its absorption because food delays and reduces its effectiveness. By taking it on an empty stomach, peak plasma levels are achieved, leading to better therapeutic outcomes in managing acid-related conditions.

Choice B rationale

Placing the capsule under the tongue is incorrect as lansoprazole is not formulated for sublingual absorption. Its intended route is oral ingestion, where it dissolves in the gastrointestinal tract for systemic absorption. Using it sublingually could result in reduced efficacy and unintended pharmacokinetic variations, undermining its role in suppressing gastric acid secretion.

Choice C rationale

Chewing the capsule is not advised because the formulation is often enteric-coated to prevent degradation in the acidic stomach environment. Crushing or chewing disrupts this protective layer, exposing the active ingredient to acid, which reduces the medication's effectiveness in controlling acid secretion.

Choice D rationale

Administering the medication four times daily is incorrect since lansoprazole is generally prescribed once daily or, in some cases, twice daily for severe conditions. Excessive dosing could lead to adverse effects such as diarrhea or nutrient malabsorption, particularly of magnesium and calcium, due to its prolonged acid suppression.

Choice A rationale

Erythema infectiosum does not typically present first on the arms. This viral infection, caused by parvovirus B19, characteristically begins with a bright red rash on the face. It can later spread to the extremities, including arms, but this is a secondary feature.

Choice B rationale

The legs are not the initial site for the rash. Fifth disease progresses from the face to the trunk and limbs. The legs are involved in the later stages, particularly during the rash's spreading phase.

Choice C rationale

The rash in erythema infectiosum first appears on the face, often described as a "slapped cheek" appearance. This hallmark feature is due to parvovirus B19's predilection for vascular endothelial cells in facial capillaries, leading to the characteristic erythema.

Choice D rationale

The abdomen is not the primary location for the rash. While the rash may extend to the trunk and abdomen as it progresses, the initial site is the face. Secondary spread occurs via hematogenous dissemination.
