A nurse is assessing a client with suspected myocardial infarction. Which finding supports this diagnosis?

Correct Answer: A

Rationale: The correct answer is A. Pain radiating to the left arm is a classic symptom of myocardial infarction, commonly known as a heart attack. This occurs due to the referred pain pathways shared by the heart and the left arm. Choices B, C, and D are incorrect. Pain relieved by rest (choice B) is more indicative of musculoskeletal pain rather than cardiac-related pain. Pain worsening with deep breathing (choice C) is often seen in conditions like pleurisy or pulmonary embolism, not myocardial infarction. Pain relieved by antacids (choice D) suggests gastrointestinal issues like heartburn or acid reflux, not cardiac-related pain.

Correct Answer: B

Rationale: The correct instruction for a client prescribed ferrous sulfate is to take it with a glass of orange juice. Vitamin C, found in orange juice, enhances the absorption of iron, making it more effective. Taking ferrous sulfate with meals, at bedtime, or with milk can decrease its absorption and effectiveness, so these options are incorrect.

Correct Answer: B

Rationale: The correct answer is B. Trouble sleeping is not a typical side effect of methadone; the nurse should clarify this misunderstanding. Choices A, C, and D are all correct statements regarding methadone. Methadone can indeed slow breathing, so it is important for the client to be aware of this effect. Avoiding alcohol while taking methadone is crucial due to the increased risk of central nervous system depression when alcohol is combined with methadone. Additionally, changing positions slowly can help prevent dizziness, which can be a side effect of methadone.

Correct Answer: A

Rationale: Placing a daily calendar in the kitchen is essential to help clients with Alzheimer's stay oriented to time and maintain cognitive function. It supports their ability to recall the day, date, and upcoming events, promoting a sense of control over their environment. Choices B, C, and D do not directly target cognitive function support in clients with Alzheimer's disease. While replacing buttoned clothing with zippered items may aid in dressing independently, changing the flooring or introducing variation in the daily routine does not specifically address cognitive function support.

Correct Answer: B

Rationale: Lethargy and confusion in a client with gastroenteritis are concerning findings that may indicate severe dehydration or electrolyte imbalance, requiring immediate intervention. While the other options are important, they do not pose an immediate life-threatening risk compared to the altered mental status in a client with gastroenteritis.
