ATI Med Surg Quiz 1 Questions
Extract:
Question 1 of 5
A nurse is preparing to administer cefazolin IVPB over 20 min. Available is cefazolin 1 g in 100 mL of dextrose 5% in water (DSW). The drop factor of the manual IV tubing is 15gtt/mL. The nurse should set the IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Calculate: (100 mL ÷ 20 min) × 15 gtt/mL = 75 gtt/min. This ensures accurate delivery of the antibiotic over the prescribed time.
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
A nurse is reviewing blood pressure classifications with a group of nurses at an in-service meeting. Which of the following should the nurse include as a risk factor for the development of hypertension?
Correct Answer: B
Rationale: Obstructive sleep apnea contributes to hypertension by causing repeated episodes of hypoxia, sympathetic nervous system activation, and increased vascular resistance. High potassium intake helps lower blood pressure, HDL of 70 mg/dL is protective, and benazepril treats hypertension, not causes it.
