Correct Answer: B

Rationale: The nurse should question the prescription to apply heat to the affected extremity for 45 minutes. Heat should not be applied in the first 48 hours after an acute injury, as it can increase swelling. Cold therapy is more appropriate initially. Choices A, C, and D are appropriate actions in the care of a client with a sprained ankle. Elevating the affected extremity helps reduce swelling, wrapping it with a compression dressing provides support, and assessing sensation, movement, and pulse every 4 hours is important to monitor for complications.

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: B

Rationale: The correct answer is B: 'Monitor for diaphoresis.' Diaphoresis, which refers to excessive sweating, is a common symptom of hypoglycemia. It indicates a low blood sugar level and should prompt immediate treatment. Polyuria (excessive urination), abdominal pain, and thirst are not typically associated with hypoglycemia. Polyuria is more commonly linked to hyperglycemia, while abdominal pain and thirst are not specific symptoms of hypoglycemia.

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: A

Rationale: In this scenario, the client is experiencing uterine hyperstimulation with contractions every 45 seconds lasting 90 seconds. This frequency and duration of contractions can lead to fetal distress. The appropriate nursing action is to discontinue the oxytocin infusion immediately to prevent complications. Increasing or maintaining the oxytocin infusion would exacerbate the situation, while decreasing it may not be sufficient to address the issue effectively.
