Correct Answer is D

Explanation

Choice A rationale
While fatigue is a common symptom of Hodgkin’s disease, it is not the most urgent symptom to address when there is significant cervical lymph node enlargement.
Choice B rationale
Pain can be a symptom of Hodgkin’s disease, but it is not the most urgent symptom to address in this case.
Choice C rationale
Fever can be a symptom of Hodgkin’s disease, but it is not the most urgent symptom to address in this case.
Choice D rationale
Stridor is a high-pitched, wheezing sound caused by disrupted airflow. Stridor may indicate a serious condition affecting the throat or larynx (voice box). With significant cervical lymph node enlargement, the lymph nodes may be pressing on the airway, causing stridor. This is a medical emergency and should be addressed first.

A. Epinephrine (Adrenaline). B. Dexamethasone (Decadron). C. 0.9% Normal Saline. D. Dobutamine (Dobutrex).

Correct Answer is A

Explanation

Choice A rationale
Epinephrine is the first-line treatment for anaphylactic shock. It works by constricting blood vessels to increase blood pressure, relaxing smooth muscles in the lungs to reduce wheezing and improve breathing, stimulating the heart, and reducing hives and swelling around the face and lips.
Choice B rationale
Dexamethasone is a corticosteroid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by reducing inflammation.
Choice C rationale
0.9% Normal Saline is a type of intravenous fluid that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by increasing fluid volume in the body to help maintain blood pressure.
Choice D rationale
Dobutamine is a medication that can be used to treat anaphylactic shock, but it is not the first-line treatment. It works by stimulating the heart muscle to increase cardiac output, which can help maintain blood pressure.
