Extract:
Question 1 of 5
A client in DKA is ordered regular insulin at 5 units per hour for the current blood glucose level. The institution protocol is to add 125 units of regular insulin to a 250 mL bag of normal saline. What is the correct rate for the nurse to set the IV pump for this dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: 10 mL/hr.
Rationale: 125 units in 250 mL = 0.5 units/mL; 5 units รท 0.5 units/mL = 10 mL/hr (
A).
Question 2 of 5
A client who receives an antihypertensive medication daily is NPO except medications for surgery. The most recent blood pressure recording is 174/88. What action should the nurse take first?

Question 3 of 5
In the operating room, an 82-year-old client tells the circulating nurse that cataract surgery is to be performed on the left eye. The nurse notes that the consent form indicates the right eye. What is the nurse's best action?
Correct Answer: A

Question 4 of 5
The nurse is transcribing a medication order and schedules dosing for 1000, 1400 and 1800. Which medication order is consistent with this schedule?
Correct Answer: C
Rationale: Propranolol 10 mg PO twice a day would not fit this schedule of three doses. Morphine sulfate is ordered every 4 hours as needed, not on a fixed schedule. Metoprolol is scheduled three times a day (1000, 1400, 1800), fitting the described schedule. Cephalexin 500 mg q 4 hours does not match the schedule as it requires dosing every 4 hours, not at the specified times.
Question 5 of 5
The nurse gives metoprolol 25 mg PO BID to a client who has coronary artery disease. The nurse understands that the primary use of this medication is to:
Correct Answer: A
Rationale: Metoprolol, a beta-blocker, reduces heart rate and myocardial oxygen demand, effectively decreasing the cardiac workload. Metoprolol does not primarily dilate coronary arteries. While it can help manage dysrhythmias, its main purpose is to reduce cardiac workload. Metoprolol does not increase the strength of myocardial contraction; it may reduce it slightly to decrease oxygen demand.
