ATI Pharmacology Assessment 2 Questions
Question 1 of 5
A patient is receiving tetracycline. Which advice should the nurse include when teaching this patient about tetracycline?
Correct Answer: A
Rationale: Tetracycline can cause photosensitivity, increasing the risk of severe sunburn. Patients should be advised to use sunscreen and avoid prolonged sun exposure. Taking antacids with tetracycline is contraindicated, as they can bind to the drug and reduce its absorption. Hearing loss and retinal damage are not associated with tetracycline use. Instead, patients should be monitored for gastrointestinal side effects and advised to take the medication with food if tolerated.
Question 2 of 5
The nurse is giving instructions to a client receiving phenytoin (Dilantin). The nurse concludes that the client has a sufficient knowledge if the client states that:
Correct Answer: D
Rationale: Monitoring serum phenytoin levels is essential to ensure therapeutic efficacy and avoid toxicity. Wearing a medical alert tag is recommended for clients on phenytoin. Alcohol should be avoided, and taking the medication with milk can interfere with absorption. Therefore, the correct statement indicating sufficient knowledge is about monitoring serum levels.
Question 3 of 5
A 29-year-old man with recurrent allergic rhinitis presents to his primary care physician for evaluation. He states that his symptoms are more problematic lately and desires treatment. He has begun on fexofenadine. Which of the following adverse reactions is possible in this patient?
Correct Answer: C
Rationale: Fexofenadine, a non-sedating antihistamine, may cause headache , a common side effect. Anxiety , cough , otitis , and respiratory infection (E) are less frequent. Its minimal CNS penetration suits rhinitis, but headache requires awareness.
Question 4 of 5
A client is prescribed prednisone for rheumatoid arthritis. Which side effect should the nurse teach the client to report immediately?
Correct Answer: C
Rationale: Prednisone, a corticosteroid, manages inflammation but risks serious side effects. Blurred vision may signal glaucoma or cataracts, ocular emergencies requiring immediate reporting to prevent vision loss. Increased appetite and weight gain are common, manageable effects of cortisol excess. Mood swings occur due to CNS effects but are less urgent unless severe. Blurred vision stands out as a rare but critical adverse reaction, linked to prednisone's long-term impact on intraocular pressure or lens opacity. Teaching this ensures early detection, aligning with corticosteroid monitoring where eye complications can escalate fast. Appetite, weight, and mood changes, while disruptive, don't match this urgency, making C the priority side effect for the client to report promptly.
Question 5 of 5
A nurse is giving a patient a loading dose of 1 mg of an antiarrhythmic drug to treat atrial flutters. Which of the following is most likely the drug being administered?
Correct Answer: A
Rationale: Digoxin is commonly used to treat atrial flutter and atrial fibrillation by helping to control the heart rate. A loading dose may be given initially to reach therapeutic levels quickly. This medication acts by increasing the force of the heart's contractions and slowing down the heart rate. Propranolol (Choice B) is a beta-blocker used to treat various heart conditions, but it is not typically used for atrial arrhythmias like atrial flutter. Ibuprofen (Choice C) is a nonsteroidal anti-inflammatory drug used for pain and inflammation, not for cardiac arrhythmias. Lithium (Choice D) is a mood-stabilizing medication often used for bipolar disorder and is not indicated for atrial flutter treatment.
