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","C","E","H"]

Explanation

The nurse anticipates the following orders from the provider based on the suspected diagnosis:

A. IV antibiotics: To treat the suspected infection.
C. Chest x-ray: To assess the lungs for signs of infection, such as pneumonia.
E. Admit to inpatient: The client's worsening condition and need for aggressive treatment warrant hospitalization.
H. Complete blood count: To assess the client's overall health status and identify any abnormalities, such as anemia or infection.

Rationale:

B. Urinalysis: While a urinalysis can be helpful in assessing for urinary tract infections, it is not a priority in this case.
D. Chest tube placement: This is not indicated unless the client develops a pleural effusion or pneumothorax.
F. Airborne precautions: This is not necessary for the client's current condition.
G. Draw an STI lab panel: While this may be relevant for the client's overall health, it is not a priority at this time, especially given the client's acute presentation.

A. "Distributive shock occurs due to increased systemic vascular resistance." B. "Distributive shock occurs due to systemic vasodilation." C. "Distributive shock occurs due to loss of myocardial contractility." D. "Distributive shock occurs due to loss of blood volume."

Correct Answer is B

Explanation

A. Increased systemic vascular resistance is typically associated with hypovolemic or cardiogenic shock, not distributive shock.
B. Distributive shock is characterized by systemic vasodilation, which leads to a decrease in systemic vascular resistance and results in inadequate tissue perfusion despite normal or increased cardiac output.
C. Loss of myocardial contractility is related to cardiogenic shock, not distributive shock.
D. Loss of blood volume is a characteristic of hypovolemic shock, whereas distributive shock occurs even when blood volume is normal due to vasodilation.
