ATI Med Surg Quiz 1 Questions
Question 1 of 5
A client who has recently traveled out of the United States comes to the emergency department with fatigue, lethargy, night sweats, and a low-grade fever. What is the nurse's first action?
Correct Answer: C
Rationale: Masking prevents potential TB transmission, a priority in infection control. A, B, and D follow after ensuring safety.
Question 2 of 5
A nurse is caring for a client who has an elevated potassium level and is on a cardiac monitor. The nurse is aware that hyperkalemia may be associated with changes to the T-wave. On the graphic, point and click on the area of the electrocardiogram (ECG) that represents the T wave.
Correct Answer: A
Rationale: The T wave, representing ventricular repolarization, is the prominent upward wave following the QRS complex. Hyperkalemia may cause tall, peaked T waves.
Question 3 of 5
The nurse receives a new client from the emergency department with an order for propranolol (Inderal). Upon looking at the client's history, which diagnosis would make the nurse clarify this order?
Correct Answer: B
Rationale: Propranolol is a nonselective beta-blocker that can cause bronchoconstriction in asthma, leading to respiratory distress. It is not contraindicated in kidney failure (though caution is needed), and it is used to treat hypertension and tachycardia.
Question 4 of 5
A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1mg/kg/dose subcutaneous every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Convert pounds to kilograms: 95 lbs ÷ 2.2 lbs/kg = 43.18 kg. Calculate dose: 1 mg/kg × 43.18 kg = 43.18 mg, rounded to 43.2 mg. This ensures accurate dosing for anticoagulation post-surgery.
Question 5 of 5
A nurse is caring for a client who has pneumonia and a prescription for oxygen therapy at 5 L/min via nasal cannula. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: A humidifier prevents nasal dryness from prolonged oxygen use. A is unsafe due to flammability risks, B disrupts oxygen delivery, and C is incorrect as the cannula is nasal, not oral.
