Correct Answer is D

Explanation

Choice A rationale:
Cardiac output is the amount of blood the heart pumps through the circulatory system in a minute. It is not the volume of blood ejected from the ventricles during each beat.
Choice B rationale:
The cardiac cycle refers to the sequence of events that occur when the heart beats. It is not the volume of blood ejected from the ventricles during each beat.
Choice C rationale:
Systole is the phase of the heartbeat when the heart muscle contracts and pumps blood from the chambers into the arteries. It is not the volume of blood ejected from the ventricles during each beat.
Choice D rationale:
Stroke volume is the volume of blood ejected from the ventricles during each beat. This is the correct answer.

A. Phenytoin 100 mg PO every 8 hr. B. Lisinopril 20 mg PO every 12 hr. C. Hold for systolic BP less than 110 mm Hg. D. Morphine 2.5 mg IV bolus PRN for incisional pain. E. Regular insulin 7 units subcutaneous 30 min before breakfast and dinner.

Correct Answer is C

Explanation

Choice A rationale:
Phenytoin 100 mg PO every 8 hr is a standard prescription for controlling seizures.
Choice B rationale:
Lisinopril 20 mg PO every 12 hr is a typical dose for treating high blood pressure.
Choice C rationale:
“Hold for systolic BP less than 110 mm Hg” is unclear because it does not specify which medication to hold.
Choice D rationale:
Morphine 2.5 mg IV bolus PRN for incisional pain is a standard prescription for pain control after surgery.
Choice E rationale:
Regular insulin 7 units subcutaneous 30 min before breakfast and dinner is a common prescription for managing blood glucose levels in diabetes patients.
