The nurse is preparing to administer a histamine 2-receptor antagonist to a client with peptic ulcer disease. What is the primary purpose of this drug classification?

A. anaphylaxis

The correct answer is A. Anaphylaxis is a severe, life-threatening allergic reaction that can occur in response to medication administration. The client's symptoms of dizziness, headache, burning feeling on extremities, and redness on face and extremities, along with the sudden onset of symptoms after starting vancomycin infusion, are indicative of a possible anaphylactic reaction.

B. arrhythmias

The correct answer is B. Arrhythmias refer to abnormal heart rhythms, which can be

triggered by various factors including medication reactions. Given the client's history of symptomatic bradycardia and the sudden onset of symptoms after starting vancomycin infusion, arrhythmias such as bradycardia or other rhythm disturbances are a concern.

C. Cardiac arrest

The correct answer is C. Cardiac arrest is the cessation of normal heart function, which can be precipitated by severe arrhythmias or anaphylaxis. The client's symptoms, along with the drop in blood pressure, indicate a potential risk of progressing to cardiac arrest if not promptly treated.

D. Necrosis

Necrosis, or tissue death, is not typically associated with the symptoms described in the scenario. While vancomycin infusion can potentially cause tissue irritation or damage at the
injection site, the symptoms described suggest a systemic reaction rather than localized tissue necrosis.

E. Renal failure

Renal failure is not directly indicated by the symptoms described in the scenario. While vancomycin can be nephrotoxic in some cases, the symptoms of dizziness, headache, and redness are more suggestive of an allergic or cardiovascular reaction.

F. Peripheral edema

Peripheral edema, or swelling in the extremities, is not indicated by the symptoms described in the scenario. The client's symptoms, such as dizziness, headache, and redness, are more
indicative of a systemic reaction rather than localized swelling.

A: Leaving the client alone could increase the risk of harm to herself or others and does not address the immediate need for safety and boundaries.
B: Clearly stating that undressing is unacceptable sets immediate boundaries, which is essential in managing acute behavioral situations, ensuring the client's dignity, and maintaining a professional environment.
C: Ignoring the behavior does not provide any guidance or boundaries for the client, which could lead to escalation or reinforce the inappropriate behavior.
D: While changing to less anxiety-provoking questions may be helpful, it does not directly address the behavior at hand, which could lead to further inappropriate actions or misunderstandings about acceptable behavior during the assessment.
