Correct Answer: A

Rationale: The correct answer is A: Pain radiating to the left arm. This is a classic symptom of myocardial infarction and indicates possible heart involvement. Reporting this finding to the provider is crucial for prompt evaluation and intervention. Choices B, C, and D are incorrect. Pain relieved by rest, pain worsened with breathing, and pain relieved by antacids are not typical symptoms of myocardial infarction. These findings do not raise the same level of concern as pain radiating to the left arm and are less indicative of cardiac involvement.

Correct Answer: A

Rationale: The correct answer is A: Constricted pupils. Constricted pupils are a classic sign of opioid intoxication, including heroin. Opioids like heroin cause the pupils to constrict due to their effect on the autonomic nervous system. Dilated pupils, increased reflexes, and elevated blood pressure are not typically associated with opioid intoxication but may be seen with other substances or conditions.

Correct Answer: C

Rationale: The correct answer is C: 'Rise slowly when sitting up.' Doxazosin can cause orthostatic hypotension, a sudden drop in blood pressure when standing up, leading to dizziness or fainting. Instructing the client to rise slowly helps prevent this adverse effect. Choices A, B, and D are incorrect. A decrease in caloric intake to reduce weight gain, an increase in dietary fiber to prevent constipation, and taking the medication each morning are not specific instructions related to managing the side effects of doxazosin.

Correct Answer: B

Rationale: The correct answer is B: Wear a dosimeter badge. When caring for a client with a sealed radiation implant, the nurse should wear a dosimeter badge to monitor radiation exposure. This badge helps measure the amount of radiation the nurse is exposed to during care. Choice A is incorrect because removing dirty linens after double-bagging is not directly related to managing radiation exposure. Choice C is incorrect as there is no specific time limit on visitors mentioned in the context of a sealed radiation implant. Choice D is incorrect as there is no evidence supporting the need for family members to stay a specific distance away from the client.

Correct Answer: C

Rationale: The correct action for a nurse when administering enoxaparin for DVT prevention is to inject the medication into the lateral abdominal wall. This is the recommended site for enoxaparin administration. Expelling the air bubble is unnecessary and may lead to a dosage error. Massaging the injection site is not recommended as it can cause bruising. Administering an NSAID for injection site discomfort is not necessary as discomfort should be minimal and transient.
