A nurse is providing teaching to the guardian of a preschooler who was newly diagnosed with a latex allergy. The nurse should include that a cross-reaction can occur with which of the following foods?
Bananas.
Grapes.
Pears.
Watermelon.
The Correct Answer is A
Choice A reason: Bananas are one of the most common foods associated with latex–fruit syndrome. This occurs because certain proteins in bananas are structurally similar to those found in natural rubber latex, leading to cross-reactivity. Other foods that may cause similar reactions include avocados, kiwis, and chestnuts. This makes bananas the correct answer because they are scientifically linked to latex allergy cross-reactions.
Choice B reason: Grapes are not typically associated with latex–fruit syndrome. While grapes can cause allergic reactions in some individuals, they do not share the same protein structures that trigger cross-reactivity with latex. Therefore, this option is incorrect.
Choice C reason: Pears are not part of the group of foods known to cross-react with latex. They are not commonly implicated in latex–fruit syndrome, making this option incorrect.
Choice D reason: Watermelon is not a food that cross-reacts with latex proteins. Although watermelon allergies exist, they are unrelated to latex allergy. This option is incorrect because it does not represent a scientifically recognized cross-reactive food.

Correct Answer is A
Explanation
Choice A reason: A flat anterior fontanel indicates adequate hydration. In dehydration, the fontanel becomes sunken, so normalization shows effective treatment.
Choice B reason: Skin turgor displaying tenting is a sign of persistent dehydration, not improvement.
Choice C reason: Hyperpnea (rapid breathing) suggests metabolic acidosis or ongoing fluid imbalance, not resolution.
Choice D reason: Cool, mottled skin indicates poor perfusion and continued dehydration, not effective treatment.
Correct Answer is B
Explanation
Choice A reason: The sterile field must always be set up at or above waist level to maintain sterility. Setting it below waist level increases the risk of contamination because the nurse cannot maintain constant visual control.
Choice B reason: Holding the bottle with the palm over the label while pouring prevents solution from running over the label, keeping it legible and dry. This is correct sterile technique and ensures safe handling of sterile solutions.
Choice C reason: Sterile items should be placed at least 2.5 cm (1 in) inside the sterile border. Placing them within 1 cm risks contamination because the edges of the sterile field are considered non-sterile.
Choice D reason: The lid of a sterile solution bottle should be placed face up on a clean surface, not within the sterile field. Placing it in the sterile field contaminates the area.
