ATI Pharmacology Practice B Questions
Question 1 of 5
The physician prescribes fluticasone (Flonase) for the client. The nurse would hold the drug and contact the physician with which assessment finding?
Correct Answer: B
Rationale: Fluticasone, Category C, requires caution in pregnancy , prompting physician consultation due to fetal risk uncertainty. Diabetes , glaucoma , and hypertension aren't immediate holds. B ensures safety, making it the key finding.
Question 2 of 5
The patient is ordered furosemide (Lasix). Before administering furosemide, it is most important for the nurse to assess the patient for allergies to which drug class?
Correct Answer: B
Rationale: Furosemide (Lasix) belongs to the sulfonamide drug class. Patients with allergies to sulfonamides may experience cross-reactivity and have an increased risk of allergic reactions to furosemide.
Therefore, it is essential for the nurse to assess the patient for any allergies to sulfonamides before administering furosemide to prevent potential adverse reactions.
Question 3 of 5
When administering Phenytoin you should monitor?
Correct Answer: D
Rationale: When administering Phenytoin, it is important to monitor all of the listed parameters - behavior, therapeutic blood levels, and for Steven Johnson syndrome.
Question 4 of 5
The health care provider is planning to discontinue a client's beta blocker. What instruction should the nurse give the client regarding the beta blocker?
Correct Answer: C
Rationale: The correct instruction for the nurse to give the client regarding discontinuing a beta blocker is that it should NOT be abruptly stopped; the dose should be tapered down. Suddenly stopping a beta blocker can lead to rebound hypertension, angina, and even heart attack in some cases. Tapering down the dose helps the body adjust gradually and reduces the risk of adverse effects associated with abrupt discontinuation. It is important for the client to follow the healthcare provider's guidance on how to safely decrease the dose of the beta blocker.
Question 5 of 5
The nurse administers medications by various routes of delivery. The nurse recognizes which route of administration as requiring higher dosages of drugs to achieve a therapeutic effect?
Correct Answer: B
Rationale: Oral drugs face first-pass metabolism in the liver, reducing bioavailability, so higher doses are needed for therapeutic effect compared to IV (100% bioavailability), sublingual (bypasses liver), or rectal (partial bypass). Oral route's loss to metabolism drives dosage needs, a pharmacokinetic distinction.
