Question 1 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.
Question 2 of 5
The student nurse is studying for a pharmacology exam and notices that many of the adrenergic blocking antagonists drugs studied in class have what suffix?
Correct Answer: B
Rationale: The suffix -lol is seen in many of the drug names for adrenergic blocking antagonists. The suffix -aine would indicate a topical anesthetic, whereas -azole indicates an antifungal, and the suffix -triptan relates to the triptans. The nurse should be familiar with drug name suffixes to aid in identifying drug classes and their therapeutic uses.
Question 3 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: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
A nurse is caring for a client who is receiving cyclobenzaprine hydrochloride (Flexeril) for the treatment of muscle spasm. Which of the following medical conditions is contraindicated with the use of the medication?
Correct Answer: B
Rationale: Cyclobenzaprine, a muscle relaxant, has anticholinergic effects that can exacerbate angle-closure glaucoma by increasing intraocular pressure. It is contraindicated in patients with this condition. While it may cause dry mouth or urinary retention, it is not specifically contraindicated in diabetes, emphysema, or urinary tract infections. The anticholinergic properties of cyclobenzaprine make it unsuitable for patients with angle-closure glaucoma.
Question 5 of 5
A client who is receiving edrophonium chloride suddenly is complaining of abdominal cramps and the nurse observes the client is experiencing increased perspiration and salivation. The nurse makes sure the availability of which of the following?
Correct Answer: C
Rationale: The symptoms of abdominal cramps, increased perspiration, and salivation suggest cholinergic excess, which can occur with edrophonium chloride. Atropine sulfate is the antidote for cholinergic toxicity and should be readily available to counteract these effects. Levodopa, methylphenidate, and carbamazepine are not used to treat cholinergic excess. Therefore, atropine is the correct medication to have on hand.
