ATI LPN Pharmacology Exam I Questions
Extract:
Question 1 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 2 of 5
The graduate nurse is aware that the count of the unit's narcotics and controlled substances at the change of shifts should involve:
Correct Answer: A
Rationale: Narcotics are controlled substances requiring strict accountability; two nurses—one ending and one starting the shift—verify counts to ensure accuracy and prevent diversion per regulatory standards. The head nurse and pharmacist may oversee inventory, but shift change counts involve direct caregivers for real-time accuracy, not administrative staff, ensuring immediate responsibility and oversight. Involving all nurses from both shifts is impractical and unnecessary; it dilutes accountability and increases error risk, as only two are needed to confirm the count efficiently. Pharmacy technicians lack authority over unit narcotics, and the charge nurse alone doesn't suffice; two nurses ensure a witnessed, reliable count per hospital policy and law.
Question 3 of 5
When preparing medications for delivery to an assigned patient, the nurse should check each medication for accuracy of drug and dose:
Correct Answer: C
Rationale: Checking medications only once increases the likelihood of errors. Safe practice requires multiple verification steps. While better than a single check, verifying only twice may still miss potential discrepancies in drug or dosage accuracy. The three-check system (when retrieving, preparing, and administering medication) minimizes errors, ensuring patient safety through consistent validation at each step. Excessive verification may delay administration, reducing practicality without significantly improving safety beyond three checks.
Question 4 of 5
A nurse is administering a dose of insulin to a patient. To practice nursing safely and effectively, the nurse should:
Correct Answer: D
Rationale: Administering insulin at proper timing correlates with mealtimes. However, this alone doesn't ensure safe practice. Confirming the injection site prevents lipodystrophy but does not address dose accuracy, which is vital for safety. Insulin is injected subcutaneously, not in the deltoid muscle. Using incorrect sites disrupts absorption. Double-checking insulin dose prevents administration errors, ensuring compliance with medication safety protocols.
Question 5 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.
