A nurse is caring for a client who has a peanut allergy. The client ate peanut butter and is now experiencing anaphylaxis. Which of the following physiological responses should the nurse expect to occur?

Blood pressure increases.

Blood vessels become more permeable.

Blood vessels constrict.

White blood cells are destroyed.

Answer and Explanation

The Correct Answer is B

A. Blood pressure does not increase during anaphylaxis; instead, it typically decreases due to vasodilation and fluid leakage.
B. During anaphylaxis, blood vessels become more permeable, leading to the release of fluids into the tissues, which causes swelling and contributes to hypotension.
C. Blood vessels do not constrict during anaphylaxis; rather, they dilate as a part of the allergic response, resulting in decreased blood pressure.
D. While there is an immune response during anaphylaxis, white blood cells are not destroyed; rather, they are activated to respond to the allergen, leading to inflammation and other systemic effects.

Correct Answer is A,B,C,D,E,F

Explanation

1. Assessing the client's airway is the priority to determine if there is any obstruction or compromise due to swelling.

2. Calling the emergency response team ensures that additional medical help is on the way if the situation worsens.

3. Applying high-flow oxygen is critical to address potential hypoxia from airway swelling.

4. Initiating IV access is necessary for administering medications.

5. Administering IV epinephrine is essential to counteract severe allergic reactions, such as angioedema.

6. Administering IV antihistamines can help alleviate symptoms but is secondary to the immediate interventions for airway management and epinephrine administration.

A. Metabolic acidosis B. Respiratory acidosis C. Respiratory alkalosis D. Metabolic alkalosis

Correct Answer is B

Explanation

A. Metabolic acidosis would be indicated by a low pH and a low HCO3, which is not present in this case since HCO3 is normal.
B. The pH of 7.32 indicates acidemia, and a PaCO2 of 50 mmHg suggests respiratory acidosis as the body is retaining carbon dioxide, contributing to the low pH. The HCO3 is normal, indicating that there is no metabolic compensation occurring.
C. Respiratory alkalosis would show a high pH and low PaCO2, which is not the case here.
D. Metabolic alkalosis would present with a high pH and elevated HCO3, which is also not present in these ABG results.
