Question 1 of 5
A nurse is caring for a client who has active pulmonary tuberculosis (TB) and a new prescription for IV rifampin. The nurse should instruct the client that they should expect to experience which of the following manifestations while taking this medication?
Correct Answer: B
Rationale: The correct answer is B: Red-coloured urine. Rifampin is known to cause a harmless side effect of discoloration of bodily fluids, such as urine, sweat, and tears, to a red-orange color. This is due to the medication's chemical properties. Staining of teeth (
A) is associated with tetracycline antibiotics, not rifampin. Constipation (
C) is not a common side effect of rifampin. Black-colored stools (
D) could be a sign of gastrointestinal bleeding but is not a typical side effect of rifampin.
Question 2 of 5
A nurse is preparing to administer ophthalmic solution to a client. Which of the following actions should the nurse take?
Correct Answer: D
Rationale: The correct answer is D: Hold the ophthalmic solution 2 cm (3/4 inch) above the lower conjunctival sac. This is the correct action because it allows the drops to be instilled accurately into the eye without touching the eye or eyelashes, reducing the risk of contamination. Holding the solution at the correct distance ensures proper delivery into the lower conjunctival sac for optimal absorption.
Choice A is incorrect because asking the client to look down is not necessary for administering ophthalmic solution.
Choice B is incorrect because instilling drops into the superior canthus can lead to improper absorption.
Choice C is incorrect as approaching the eye from below may increase the risk of contamination.
Question 3 of 5
A provider prescribes a sublingual medication for a client who has an NG tube in place. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: The correct answer is C: Administer the medication under the client's tongue. Sublingual medications are meant to be absorbed directly into the bloodstream through the mucous membranes under the tongue. This route bypasses the digestive system, making it an effective option when the client has an NG tube in place. Administering the crushed medication through the NG tube (choice
A) may not provide the desired effect as the medication is designed for sublingual absorption. Dissolving the medication in water and giving it through the NG tube (choice
B) may alter the drug's intended pharmacokinetics. Requesting a prescription for an oral formulation of the medication (choice
D) may not be necessary if the sublingual route is appropriate.
Question 4 of 5
Which medication route provides the most rapid onset of a medication but also poses the greatest risk of adverse effect if administered incorrectly?
Correct Answer: D
Rationale: The correct answer is D: Intravenous (IV). IV route provides the most rapid onset as it bypasses first-pass metabolism and directly enters the bloodstream. However, it poses the greatest risk of adverse effects if administered incorrectly due to rapid systemic distribution. Subcutaneous (
A), intradermal (
B), and intramuscular (
C) routes have slower onset compared to IV and are less risky in terms of adverse effects as they have a more localized impact before entering the bloodstream. IV administration requires precise dosing and careful monitoring to prevent adverse reactions.
Question 5 of 5
A nurse is caring for a client who has an infection and a prescription for gentamicin Intermittent IV bolus every 8 hr. A peak and trough are required with the next dose. Which of the following actions should the nurse take to obtain an accurate gentamicin serum level?
Correct Answer: B
Rationale: The correct answer is B. Drawing a trough level immediately before administering the medication ensures the lowest concentration of the drug in the client's bloodstream, providing an accurate baseline. Drawing a peak level 30 minutes after the dose allows the nurse to measure the highest concentration of the drug, which indicates how well the body metabolizes and eliminates the medication. This timing ensures accurate assessment of both peak and trough levels for monitoring gentamicin therapeutic levels. Option A is incorrect because drawing a peak level before the medication administration can result in a falsely elevated level due to the drug being freshly administered. Option C is incorrect as the timing is not aligned with the medication administration schedule, leading to inaccurate results.
