ATI LPN Pharmacology Exam I Questions
Extract:
Question 1 of 5
Which of these is the correct way for a nurse to document medication administration?
Correct Answer: C
Rationale: Recording at shift's end risks memory errors or omissions; delayed documentation compromises accuracy and legal accountability for controlled substances and patient care. Pharmacy technicians don't administer drugs; nurses document their own actions, ensuring responsibility and precision in the medication administration record. Immediate recording post-administration ensures accuracy, timeliness, and compliance with standards; it reflects real-time events, reducing errors in patient care documentation. Recording others' actions is inaccurate and unethical; nurses must document only their administrations, maintaining individual accountability and patient safety.
Question 2 of 5
The nurse explains to a client that the drug administration of a medication is to be placed between the gum and jaw. By which route is the nurse administering this medication?
Correct Answer: C
Rationale:
Topical applies to skin or mucous surfaces broadly; gum/jaw placement is specific to buccal, not the general external or mucosal topical category. Oral means swallowed; buccal drugs stay in the mouth for absorption, avoiding the digestive tract, making this an incorrect route classification. Buccal involves placement between gum and cheek; it allows direct mucosal absorption into the bloodstream, bypassing first-pass metabolism effectively. Sublingual is under the tongue; gum/jaw specifies buccal, as sublingual targets a different oral site with distinct absorption dynamics.
Question 3 of 5
See the syringe diagram, what part is #7? (Assuming #7 refers to a common syringe part; no diagram provided, so standard parts assumed.)
Correct Answer: B
Rationale: 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. The plunger, often numbered high in diagrams, moves to draw or inject; its dynamic function in volume control makes it a likely #7 candidate. 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. The tip connects the needle; a minor component, it's rarely highlighted as #7, overshadowed by the plunger or barrel in functional importance.
Question 4 of 5
Using the label, what is the strength of the medication? (No label; assuming Zestril from prior context.)
Correct Answer: A
Rationale: Zestril at 5 mg per tablet is common; strength is the dose per unit, and this matches typical labeling for hypertension management effectively. 10 mg is a Zestril strength but not assumed here; without label confirmation, 5 mg is the base unit from prior context, not this option. 15 mg isn't standard for Zestril tablets; it's a total dose possibility, not a per-tablet strength, mismatching typical medication packaging norms. 20 mg exists for Zestril but isn't the default; 5 mg aligns with the supplied strength in earlier questions, making it the likely label.
Question 5 of 5
A patient is to receive insulin Regular and insulin NPH. How will the nurse draw up the insulins for administration?
Correct Answer: B
Rationale: Separate syringes increase injection sites and patient discomfort; mixing is standard as Regular and NPH are compatible, optimizing insulin delivery efficiency and absorption. 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. Shaking insulin damages its structure; NPH requires gentle rolling to mix, while Regular needs no mixing, making vigorous shaking inappropriate for preparation. 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.
