Question 1 of 5
The nurse is to administer enteral medications to a patient who cannot swallow and is receiving continuous enteral feedings. Which is correct concerning administration of the enteral medications?
Correct Answer: B
Rationale: Liquid medications should be diluted before administration through a feeding tube to prevent clogging and ensure proper absorption. Adding medications to the enteral solution (A) is not recommended, as it can alter the formula's composition and stability.
Question 2 of 5
When applying transdermal nitroglycerin patches, which instruction by the nurse is correct?
Correct Answer: A
Rationale: The correct instruction by the nurse when applying transdermal nitroglycerin patches is to "Rotate application sites with each dose." This is important to prevent skin irritation and tolerance to the medication. It is recommended to apply the patch to a different, clean, hairless area of skin for each dose to ensure proper absorption and effectiveness of the medication. Additionally, rotating application sites helps reduce the risk of skin reactions such as redness, itching, or rash.

Question 4 of 5
With regard to oral anti-asthmatic agents:
Correct Answer: C
Rationale: Prednisone is intermediate-acting (12-36 hours), not long-acting like dexamethasone, so that's false. Methotrexate benefits some prednisone-dependent asthmatics, not all studies, making that false. Cyclosporin's toxicity (e.g., nephrotoxicity) limits its anti-asthmatic use, a true statement, despite immunosuppressive potential. Nifedipine has minimal effect on exercise-induced bronchoconstriction, unlike inhaled CCBs, so that's false. Macrolides show some benefit in asthma. Cyclosporin's limitation reflects its risk-benefit profile, restricting its practical use.
Question 5 of 5
Which of the following salicyclates is less effective than aspirin, but may be used in patients allergic to aspirin:
Correct Answer: C
Rationale: Salicylamide is less effective than aspirin but may be used in patients allergic to aspirin. It is a derivative of salicylic acid and acts as an analgesic and antipyretic, but it lacks the anti-inflammatory properties of aspirin. Sodium salicylate and acetylsalicylic acid (aspirin) are more effective than salicylamide. Methyl salicylate is mainly used as a topical analgesic. Diflunisal is a salicylate derivative that is more potent and has a longer duration of action compared to aspirin, so it is not a suitable alternative for patients allergic to aspirin.
