ATI LPN Pharmacology Exam I Questions
Extract:
Question 1 of 5
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?
Correct Answer: D
Rationale: PRN is as needed; EKGs here are routine, not symptom-driven, making this inapplicable to a standard admission protocol for all patients. One-time is a single event; this order applies to all admissions ongoing, not a one-off, distinguishing it from limited-duration directives. STAT is immediate; routine EKGs aren't urgent, occurring as part of standard care, not requiring the priority of acute intervention orders. Standing orders apply automatically to all qualifying patients; this EKG protocol fits, ensuring consistent cardiac assessment unless overridden.
Question 2 of 5
Which is the priority action of the nurse immediately after administration of an intramuscular injection?
Correct Answer: C
Rationale: Informing the patient is secondary; it addresses communication but not immediate safety risks like needlestick injury, which is a higher priority post-injection per occupational health standards. Assessing comfort is important but not urgent; pain evaluation can wait after securing the needle, as safety from sharps exposure outweighs immediate patient feedback in priority. Engaging the safety sheath prevents needlestick injuries; it's the priority action to protect the nurse and others from bloodborne pathogens, aligning with universal precautions post-injection. Checking for bleeding is routine but not critical; minor oozing is common and manageable later, while needle safety is an immediate concern to prevent infection risks.
Question 3 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 4 of 5
Vistaril 75 mg IM is ordered for anxiety. Available: 50 mg/mL. How many milliliters will the nurse administer?
Correct Answer: B
Rationale: 1 mL gives 50 mg; this underdoses the 75 mg order, reducing Vistaril's sedative effect, risking inadequate anxiety relief for the patient. 1.5 mL is correct; 75 mg divided by 50 mg/mL equals 1.5 mL, delivering the precise IM dose for effective anxiolytic action safely. 2 mL provides 100 mg; this overdoses Vistaril, risking excessive sedation or hypotension, exceeding the ordered therapeutic amount unnecessarily. 2.5 mL yields 125 mg; this far exceeds 75 mg, amplifying side effects like drowsiness or respiratory depression, unsafe for anxiety management.
Question 5 of 5
After the nurse hands a client a medication, the client says, 'What is this red tablet for? I have always taken a yellow pill.' What is the most appropriate action for the nurse to take?
Correct Answer: A
Rationale: Withholding and rechecking ensures safety; a color change signals a potential error, and verifying the MAR against orders prevents administering the wrong drug. Assuming a change is risky; without confirmation, administering an unverified drug could harm the patient if it's not the intended prescription. Administering then checking later endangers the patient; a wrong drug could cause adverse effects, and delayed verification violates safety protocols. Describing and giving without verification is unsafe; the red tablet may not match the order, risking incorrect treatment or allergic reactions.
