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 will be administering an antitussive medication containing codeine to a patient. What is the priority assessment?
Correct Answer: C
Rationale: Codeine, an opioid antitussive, can cause respiratory depression as a side effect. The nurse must assess the patient’s respiratory rate before administration to ensure it is within a safe range (typically >12 breaths per minute). While lung sounds (B) and sputum consistency (D) are important, they are not the priority when administering a medication that can suppress respiration. Pulse oximetry (A) is useful but secondary to direct respiratory rate assessment.
Question 3 of 5
Colchicine is prescribed for a client with gout. The nurse reviews the client’s record, knowing that this medication would be used in caution in which of the following medical conditions?
Correct Answer: B
Rationale: Colchicine should be used with caution in patients with aplastic anemia or other blood dyscrasias, as it can exacerbate bone marrow suppression. While colchicine is used to treat conditions like Behcet disease and familial Mediterranean fever, it is not contraindicated in these conditions. Amyloidosis is not a primary concern with colchicine use. Monitoring blood counts is essential in patients with pre-existing hematologic conditions.
Question 4 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 5 of 5
Which of the following antibacterials is most suitable for treatment of a lower urinary tract infection in a 28-year-old woman who is 10 weeks pregnant?
Correct Answer: A
Rationale: UTI in pregnancy needs safe, effective antibiotics. Amoxicillin, a penicillin, is safe (category B), effective against common pathogens (e.g., E. coli), and suitable in early pregnancy. Trimethoprim risks folate antagonism, avoided in first trimester. Tetracycline causes fetal bone/teeth damage, contraindicated. Erythromycin and flucloxacillin are less targeted for UTI. Amoxicillin's safety and efficacy make it ideal, protecting mother and fetus.
