A nurse is providing care to a client who is experiencing wheezing after receiving an antibiotic 20 min ago. Which of the following findings is the priority of the nurse to monitor for?
A.
Decreased blood pressure
B.
Stomach pain
C.
Urticaria
D.
Lightheadedness
The Correct Answer and Explanation is :
In this scenario, the priority finding for the nurse to monitor is:
A. Decreased blood pressure
Explanation
Wheezing following the administration of an antibiotic raises concerns for an allergic reaction or anaphylaxis. Anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen, including medications such as antibiotics. It is characterized by a cascade of physiological responses that can affect multiple systems in the body.
1. Understanding Anaphylaxis: Anaphylaxis involves the sudden release of histamine and other mediators from mast cells and basophils. This response causes widespread vasodilation, leading to a drop in blood pressure (hypotension), which can result in shock. Other symptoms of anaphylaxis include wheezing, urticaria (hives), abdominal pain, and lightheadedness.
2. Importance of Monitoring Blood Pressure: Monitoring blood pressure is crucial because hypotension is a key indicator of anaphylaxis. A significant drop in blood pressure can lead to inadequate perfusion of vital organs, resulting in severe complications or even death if not promptly addressed. Early recognition of hypotension allows for immediate intervention, such as the administration of epinephrine, which is the first-line treatment for anaphylaxis.
3. Comparison with Other Findings:
- Decreased Blood Pressure (A): A decrease in blood pressure is a direct sign of anaphylaxis and requires urgent action.
- Stomach Pain (B): While abdominal pain can occur in anaphylaxis, it is not as immediately life-threatening as hypotension.
- Urticaria (C): Urticaria is a common allergic reaction symptom, but by itself, it does not pose an immediate threat compared to hypotension.
- Lightheadedness (D): Lightheadedness may occur due to hypotension or other factors but is less specific and less immediately critical than decreased blood pressure.
In summary, decreased blood pressure is the most critical finding to monitor in a client experiencing wheezing after an antibiotic administration because it directly indicates a potential anaphylactic reaction, which requires immediate medical intervention.
