ATI Med Surg Quiz 1 Questions
Question 1 of 5
A nurse is teaching a group of clients about risk factors for developing peripheral artery disease. Which of the following risk factors should the nurse include in the teaching?
Correct Answer: C
Rationale: A BMI of 35 (obesity) is a significant risk factor for peripheral artery disease (PA
D) because excess body weight contributes to atherosclerosis, hypertension, and diabetes—all of which impair circulation. Rheumatic fever primarily affects the heart valves and is not a risk factor for PAD. Venous thrombosis affects veins, whereas PAD is a disease of arteries. Chronic pulmonary disease affects the lungs but does not directly contribute to PAD development.
Question 2 of 5
A nurse is caring for a patient diagnosed with hypokalemia. Which of the following ECG findings would the nurse expect to observe in a patient with severe hyperkalemia?
Correct Answer: C
Rationale: Tall, peaked T waves are a hallmark ECG finding in hyperkalemia, especially when potassium levels exceed 6.0 mEq/L. A depressed ST segment and U waves are characteristic of hypokalemia, not hyperkalemia. T wave inversions occur in ischemia, not hyperkalemia.
Question 3 of 5
A nurse is monitoring a client who is on telemetry. Which of the following findings on the ECG strip should the nurse recognize as normal sinus rhythm?
Correct Answer: C
Rationale: A QRS duration of 0.06-0.10 seconds is normal and suggests normal conduction through the ventricles in normal sinus rhythm. The P wave should come before the QRS complex, a PR interval >0.20 seconds suggests first-degree AV block, and an inverted T wave suggests myocardial ischemia.
Question 4 of 5
The nurse is caring for a client diagnosed with Raynaud's phenomena. The nurse will prioritize educating the client about implementing which intervention?
Correct Answer: A
Rationale: Avoiding cold exposure is critical because cold can trigger vasospasms of small arteries in the fingers and toes, leading to pain, pallor, cyanosis, and numbness. Stress is a major trigger for Raynaud's episodes, loose warm gloves are recommended, and caffeine is a vasoconstrictor that can worsen symptoms.
Question 5 of 5
A nurse is assessing a client who has bradycardia. Which of the following findings should the nurse expect?
Correct Answer: D
Rationale: Lightheadedness occurs due to decreased cardiac output from a slow heart rate in bradycardia. Fluid volume deficit usually causes tachycardia, anxiety increases heart rate, and fever also increases heart rate, not decreases it.
