A nurse is collecting data from a client who has a history of angina and reports having a dull chest pressure that radiates to the left side of his neck. Which of the following is the priority medication the nurse should anticipate the provider prescribing?
Nifedipine
Nitroglycerin
Atenolol
Clopidogrel
The Correct Answer is B
Rationale:
A. Nifedipine: Nifedipine is a calcium channel blocker that helps reduce myocardial oxygen demand by decreasing afterload and dilating coronary arteries. However, it is not the priority in acute chest pain management because it has a slower onset compared to nitroglycerin.
B. Nitroglycerin: Nitroglycerin is the priority medication for acute angina. It works rapidly by dilating coronary arteries and reducing myocardial oxygen demand, which helps relieve chest pressure and prevent progression to myocardial infarction.
C. Atenolol: Atenolol, a beta-blocker, decreases heart rate and contractility to reduce myocardial oxygen consumption. While useful for long-term angina management, it is not the first-line agent for immediate chest pain relief in acute settings.
D. Clopidogrel: Clopidogrel is an antiplatelet agent that prevents clot formation, often used in long-term management or following stent placement. It does not provide immediate relief from angina and is therefore not the priority medication in this scenario.

Correct Answer is B
Explanation
Rationale:
A. "We've seen steady improvement in other clients who are depressed.": While this may sound reassuring, it provides generalized information that may create unrealistic expectations. It does not address the partner’s specific concerns or open up a dialogue for emotional support or understanding.
B. "Tell me what you know about depression,": This response encourages open communication and assesses the partner's understanding of the condition. It allows the nurse to provide accurate, individualized information and emotional support based on what the partner already knows or believes.
C. "No one really knows the answer to that question.": Though factually true, this statement may seem dismissive or lacking empathy. It does not invite discussion or support the emotional needs of the partner, who is likely feeling uncertain or overwhelmed.
D. "The important thing is that he gets better, not how long it takes.": This response minimizes the partner’s valid concern about recovery time. It may come across as invalidating and does not provide helpful or therapeutic communication.
Correct Answer is A
Explanation
Rationale:
A. Swelling of the lips: Swelling of the lips can be an early sign of anaphylaxis, a severe allergic reaction. Epinephrine is the first-line treatment for anaphylaxis because it rapidly reduces airway swelling, improves breathing, and supports blood pressure by constricting blood vessels.
B. Nausea: While nausea may occur during an allergic reaction, it is not a primary life-threatening symptom addressed by epinephrine. Epinephrine targets cardiovascular and respiratory symptoms more directly, not gastrointestinal discomfort.
C. Hand tremors: Tremors are actually a potential side effect of epinephrine due to its stimulation of the sympathetic nervous system. The medication is not intended to treat tremors and may even cause or worsen them temporarily.
D. Hyperglycemia: Epinephrine can increase blood glucose levels as a side effect, but it is not prescribed to treat or manage hyperglycemia. Managing blood glucose is not part of the therapeutic purpose of this emergency medication.
