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 B
Explanation
Choice A reason: Separate syringes increase injection sites and patient discomfort; mixing is standard as Regular and NPH are compatible, optimizing insulin delivery efficiency and absorption.
Choice B reason: Drawing Regular (clear) before NPH (cloudy) in one syringe prevents contamination of the short-acting vial with the intermediate-acting insulin, ensuring accurate dosing and stability.
Choice C reason: Shaking insulin damages its structure; NPH requires gentle rolling to mix, while Regular needs no mixing, making vigorous shaking inappropriate for preparation.
Choice D reason: Drawing NPH first risks contaminating the Regular vial with NPH particles, altering its rapid action; the clear-to-cloudy sequence maintains insulin integrity and efficacy.
Correct Answer is B
Explanation
Choice A reason: The barrel holds the medication; it’s the main body, not typically #7, and its static role doesn’t involve direct manipulation like other parts.
Choice B reason: The plunger, often numbered high in diagrams, moves to draw or inject; its dynamic function in volume control makes it a likely #7 candidate.
Choice C reason: The needle pierces tissue; usually a lower number, it’s distinct from the syringe’s operational core, less likely to be #7 in standard layouts.
Choice D reason: The tip connects the needle; a minor component, it’s rarely highlighted as #7, overshadowed by the plunger or barrel in functional importance.
