Correct Answer: A

Rationale: The correct answer is A: 'Smokes one pack of cigarettes daily.' Smoking is a major risk factor for angina and other cardiovascular diseases due to its impact on blood vessels. Choice B, 'Drinks two beers daily,' is not directly associated with angina pectoris. While excessive alcohol consumption can contribute to heart problems, it is not a primary risk factor for angina. Choice C, 'Works in a job that requires exposure to the sun,' is not typically related to angina pectoris. Sun exposure is more closely linked to skin-related conditions. Choice D, 'Eats while lying in bed,' is also not a common risk factor for angina. While certain eating habits can impact heart health, this specific behavior is not directly associated with angina pectoris.

Correct Answer: A

Rationale: Correct! Monitoring INR is essential in clients on anticoagulant therapy to ensure the blood's clotting time is within the therapeutic range, preventing further embolic events or excessive bleeding. Monitoring blood glucose levels (Choice B), blood pressure (Choice C), and temperature (Choice D) is important for various other conditions but is not directly related to anticoagulant therapy for a client with a history of pulmonary embolism.

Correct Answer: D

Rationale: The correct answer is 'Wear long sleeves and pants.' This instruction is crucial in reducing the risk of Lyme disease because it helps minimize exposure to ticks that carry the disease. Ticks are commonly found in grassy and wooded areas, so covering up with long sleeves and pants can act as a physical barrier and prevent ticks from attaching to the skin. Choices A, B, and C are not directly related to preventing Lyme disease. Washing hands frequently is important for general hygiene but not specifically for preventing tick bites. Avoiding drinking lake water is more about preventing waterborne illnesses rather than Lyme disease. Not sharing personal products is important for preventing the spread of infections but is not directly related to Lyme disease prevention.

Correct Answer: B

Rationale: The priority nursing action in this scenario is to perform an ECG. An ECG is crucial in confirming myocardial infarction promptly and guiding immediate treatment decisions. Administering oxygen as prescribed is important but not the priority over confirming the diagnosis. Obtaining a detailed health history is relevant but does not take precedence over immediate diagnostic confirmation. While monitoring vital signs regularly is essential, performing an ECG is the priority action in this scenario to guide timely management.

Correct Answer: B

Rationale: To calculate the infusion rate for vancomycin, you need to divide the total volume by the total time of infusion. In this case, the total volume is 100 mL, and the total time is 1.5 hours. Therefore, 100 mL · 1.5 hours = 67 mL/hour. This means the nurse should program the infusion pump to deliver vancomycin at a rate of 67 mL/hour. Choice A (50) is incorrect as it does not reflect the correct calculation. Choice C (57) is incorrect as it is not the accurate calculation based on the provided information. Choice D (70) is incorrect as it does not correspond to the correct infusion rate calculation.
