Question 1 of 5
What is the generic name on the medication? (No medication specified; assuming a common example from context, e.g., Zestril.)
Correct Answer: A
Rationale: Lisinopril is Zestril's generic name; an ACE inhibitor, it's widely used for hypertension, matching the context of a common medication order. Acetaminophen, a pain reliever, isn't Zestril's generic; it lacks antihypertensive action, making it irrelevant to the implied medication class. Morphine, an opioid, treats pain, not hypertension; it doesn't align with Zestril's purpose or class, ruling it out as the generic name. Fentanyl, another opioid, addresses pain, not blood pressure; it's unrelated to Zestril's therapeutic role, excluding it from consideration.
Question 2 of 5
A nurse has an order to administer a schedule II drug to a patient. When working with medications of this type, the responsibility of the nurse is to:
Correct Answer: B
Rationale: Checking with another nurse may occur, but it's not mandatory for all schedule II drugs; documentation is the primary legal responsibility to track controlled substances accurately. Signing out on a narcotic sheet is required; schedule II drugs like opioids need strict tracking to prevent diversion, ensuring accountability per federal and hospital regulations. Leaving medication at the bedside violates security; schedule II drugs must remain controlled, as unattended narcotics risk theft or misuse, breaching safety protocols entirely. Extra water is irrelevant to responsibility; it's a hydration tip, not a legal or safety duty tied to administering highly regulated schedule II controlled substances.
Question 3 of 5
A patient consumes 120 mL of orange juice and 120 mL of milk for breakfast, 260 mL of coffee for lunch, and 90 mL of an ice pop and 120 mL of ice cream for dinner. Calculate the intake for the 6 AM to 6 PM shift.
Correct Answer: B
Rationale: 610 mL omits ice cream (120 mL); total is 120+120+260+90+120=710 mL; this undercalculation misses a key liquid intake component. 710 mL sums all: 120 (juice) + 120 (milk) + 260 (coffee) + 90 (ice pop) + 120 (ice cream); melted solids count as fluid, matching clinical standards. 810 mL overestimates; no additional fluids are listed beyond 710 mL; this error likely adds non-existent intake, skewing the total inaccurately. 910 mL vastly exceeds reality; it may double-count or invent fluids; only 710 mL is supported by the listed consumption data provided.
Question 4 of 5
A nurse is preparing to administer an intramuscular injection for a client of average weight. At what angle would the nurse insert the needle?
Correct Answer: A
Rationale: IM injections use a 90-degree angle; this ensures deep muscle penetration for average-weight adults, optimizing drug absorption into vascular tissue. 45 degrees is for subcutaneous injections; it's too shallow for IM, risking fat deposition instead of muscle, reducing efficacy in this context. 15 degrees is far too shallow; it's not a standard angle, likely depositing drug in skin layers, failing to reach muscle for intended absorption. 25 degrees mimics subcutaneous; it doesn't reach muscle depth, compromising IM delivery and therapeutic effect in an average-weight client.
Question 5 of 5
Which nursing action is appropriate when pulling the plunger of the syringe back prior to administering medication and blood is aspirated in the syringe?
Correct Answer: A
Rationale: Blood aspiration indicates vascular entry; discarding prevents IV administration of a drug meant for another route, avoiding rapid absorption risks or contamination. Giving despite blood risks unintended IV delivery; drugs like IM injections aren't formulated for this, potentially causing toxicity or embolism. Changing the needle doesn't address blood-mixed medication; it remains unsafe for injection, as the dose is compromised and potentially contaminated. Omitting skips treatment unnecessarily; the issue is procedural, not the order, and restarting ensures the patient receives the intended therapy safely.
