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.

Answer and Explanation

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 D

Explanation

Choice A reason: A decrease in blood pressure is not characteristic of autonomic dysreflexia. Instead, autonomic dysreflexia typically causes a sudden and severe increase in blood pressure due to sympathetic nervous system overactivity triggered by stimuli below the level of injury. This option is incorrect.

Choice B reason: An increase in heart rate is not typical of autonomic dysreflexia. In fact, bradycardia (decreased heart rate) often occurs due to parasympathetic compensation in response to hypertension. Therefore, this option is incorrect.

Choice C reason: Eye twitching is not a recognized symptom of autonomic dysreflexia. The hallmark symptoms include severe hypertension, pounding headache, flushing, sweating above the level of injury, and nasal congestion. This option is incorrect.

Choice D reason: A sudden, severe headache is a hallmark symptom of autonomic dysreflexia. It results from acute hypertension caused by noxious stimuli such as bladder distention, fecal impaction, or skin irritation below the level of injury. This makes option D the correct answer.

A. Massage the area to improve circulation B. Provide the client with an alternating pressure mattress C. Apply a sterile, dry gauze dressing over the client's wound D. Place a donut-shaped cushion under the client when in a chair

Correct Answer is B

Explanation

Choice A reason: Massaging the area of a pressure ulcer is contraindicated. Massage can damage fragile capillaries and tissues, worsening the ulcer and increasing the risk of further breakdown. It may also cause pain and inflammation. Therefore, this intervention is inappropriate for a stage II ulcer.

Choice B reason: An alternating pressure mattress is an evidence-based intervention that helps redistribute pressure across the body and reduces the risk of further skin breakdown. For a comatose client who cannot reposition themselves, this intervention is especially important. It promotes circulation and prevents worsening of the ulcer, making it the most appropriate choice.

Choice C reason: A sterile, dry gauze dressing is not the recommended treatment for a stage II ulcer. Stage II ulcers involve partial-thickness skin loss and require a moist wound environment to promote healing. Dry gauze can adhere to the wound bed, cause trauma during removal, and delay healing. Moist dressings such as hydrocolloids or foam dressings are preferred.

Choice D reason: Donut-shaped cushions are not recommended because they concentrate pressure around the wound edges, worsening ischemia and tissue damage. They can increase the risk of ulcer progression rather than prevent it. This intervention is inappropriate for pressure ulcer management.
