ATI Nur 221 Med Surg Exam Cardiac Questions
Extract:
Question 1 of 5
A client with a diagnosis of heart failure is admitted to the cardiac unit. Which intervention should the nurse complete first?
Correct Answer: C
Rationale: Auscultating the lung and heart sounds is correct. In heart failure, pulmonary congestion and fluid overload can lead to respiratory distress. Immediate assessment for crackles, wheezing, or abnormal heart sounds evaluates for acute decompensation. Drawing a BMP, obtaining a health history, and assessing pulse and temperature are important but secondary to assessing for immediate respiratory or cardiac compromise.
Question 2 of 5
A nurse is caring for a client who has a pulmonary embolism and has a new order for enoxaparin 1.5 mg/kg/dose to be administered subcutaneously every 12 hours. The client weighs 176 pounds. How many mg should the nurse administer per dose? (Round to the nearest whole number)
Correct Answer: C
Rationale: The correct answer is 120 mg. Convert 176 pounds to kilograms (176 / 2.2 = 80 kg). Calculate the dose: 80 kg × 1.5 mg/kg = 120 mg. This matches the provided correct answer, so option C (120 mg) is correct.
Question 3 of 5
The nurse knows that which of the following positions is the best position for a client diagnosed with COPD?
Correct Answer: A
Rationale: Sitting up and leaning over the bedside table (tripod position) maximizes lung expansion and improves oxygenation in COPD. Fowler's position, recliner, and prone positions are less effective.
Question 4 of 5
A client came into the emergency room with a possible myocardial infarction. The provider orders a series of blood tests to be drawn, which lab should the nurse anticipate will be drawn?
Correct Answer: C
Rationale: Troponin is correct. Cardiac-specific troponins are the gold standard for detecting myocardial injury, crucial for diagnosing myocardial infarction. BNP, LDH, and creatinine are not primary markers for MI.
Question 5 of 5
A client who has coronary artery disease tells the nurse he is afraid of dying from a heart attack. Which of the following responses should the nurse make?
Correct Answer: B
Rationale: Encouraging the client to express fears allows emotional support and assessment. Providing health advice, dismissing fears, or referring to a physician too soon misses the opportunity for immediate support.
