A nurse is caring for a client who is starting to take aspirin 81 mg daily. Which of the following findings should the nurse identify as a risk factor for the client's development of an aspirin-induced ulcer?

The nurse should expect angioedema as one of the manifestations of anaphylaxis in a client experiencing an allergic reaction to an antibiotic. Angioedema is a severe swelling that occurs beneath the skin, typically affecting the face, lips, tongue, throat, or other body parts. It is a result of the release of histamine and other inflammatory mediators in response to the allergen.

Anaphylaxis is a life-threatening allergic reaction that can occur rapidly and affect multiple body systems. In addition to angioedema, other common manifestations of anaphylaxis include:

• Difficulty breathing or wheezing due to bronchospasm

• Hives or urticaria, which are itchy raised skin rashes

• Severe itching or tingling sensation

• Rapid and weak pulse

• Low blood pressure leading to hypotension

• Nausea, vomiting, or diarrhea

• Feeling of impending doom or anxiety

Let's go through the other options:

A. Hypertonic reflexes: This is not a manifestation of anaphylaxis. "Hypertonic reflexes" are not typically associated with allergic reactions or anaphylaxis. Hypertonic reflexes refer to increased muscle tone, but they are not part of the usual presentation of anaphylaxis.

B. Increase in systolic blood pressure: Anaphylaxis usually leads to a decrease in blood pressure rather than an increase. The decrease in blood pressure can be severe and result in shock, which is a life-threatening condition.

D. Urinary retention: Urinary retention is not a common manifestation of anaphylaxis. Anaphylaxis primarily affects the respiratory and circulatory systems, leading to airway constriction, difficulty breathing, and cardiovascular collapse. Urinary retention is not directly related to the pathophysiology of anaphylaxis.

To calculate the rate at which the IV pump should deliver dopamine, we can follow these steps:

Step 1: Convert the weight of the client from pounds to kilograms.

220 lb ÷ 2.2 = 100 kg (rounded to the nearest whole number)

Step 2: Calculate the total dose of dopamine per minute.

5 mcg/kg/min × 100 kg = 500 mcg/min

Step 3: Convert the dose from micrograms (mcg) to milligrams (mg).

500 mcg/min ÷ 1000 = 0.5 mg/min

Step 4: Determine the infusion rate in milliliters per hour (mL/hr).

The total volume of the solution is 250 mL.

The total dose of dopamine is 400 mg.

So, the infusion rate is (0.5 mg/min ÷ 400 mg) × 250 mL = 0.3125 mL/min.

Step 5: Convert the infusion rate from mL/min to mL/hr.

0.3125 mL/min × 60 min/hr = 18.75 mL/hr (rounded to the nearest tenth).

Therefore, the nurse should set the IV pump to deliver 18.8 mL/hr (rounded to the nearest tenth).
