The patient is admitted to the cardiac unit. Everyone admitted to the cardiac unit will have an EKG done unless otherwise ordered. This is an example of which type of order?
PRN
One-time
STAT
Standing
The Correct Answer is D
Choice A reason: PRN is as needed; EKGs here are routine, not symptom-driven, making this inapplicable to a standard admission protocol for all patients.
Choice B reason: One-time is a single event; this order applies to all admissions ongoing, not a one-off, distinguishing it from limited-duration directives.
Choice C reason: STAT is immediate; routine EKGs aren’t urgent, occurring as part of standard care, not requiring the priority of acute intervention orders.
Choice D reason: Standing orders apply automatically to all qualifying patients; this EKG protocol fits, ensuring consistent cardiac assessment unless overridden.

Correct Answer is A
Explanation
Choice A reason: Flow rate is volume divided by time; 250 mL over 4 hours equals 62.5 mL/hr, ensuring safe transfusion pacing to avoid fluid overload or hemolysis.
Choice B reason: 125 mL/hr assumes 250 mL over 2 hours; this doubles the ordered rate, risking circulatory overload and transfusion reactions in a standard protocol.
Choice C reason: 250 mL/hr infuses the unit in 1 hour; this rapid rate exceeds safe limits, potentially causing hypertension or pulmonary edema in vulnerable patients.
Choice D reason: 500 mL/hr is far too fast, implying 250 mL in 30 minutes; this dangerous speed could trigger severe hemolytic reactions or cardiovascular collapse.
Correct Answer is C
Explanation
Choice A reason: Four times (6:00 a.m., noon, 6:00 p.m., midnight) is QID, not TID; TID means three times daily, and this schedule overdoses the patient unnecessarily.
Choice B reason: Six times daily is every 4 hours, not TID; this exceeds the three-dose requirement, risking toxicity or side effects from excessive administration frequency.
Choice C reason: 9:00 a.m., 1:00 p.m., 5:00 p.m. is TID; spaced 8 hours apart, it aligns with standard three-times-daily dosing, ensuring consistent therapeutic levels safely.
Choice D reason: Meal and bedtime timing is vague; without fixed hours, it risks uneven dosing intervals, potentially disrupting pharmacokinetics and efficacy of the medication.
