ATI Pharmacology Assessment 2 Questions
Question 1 of 5
The nurse assesses the patient receiving phentolamine (Regitine) and suspects what finding is an adverse effect of the medication?
Correct Answer: C
Rationale: Patients receiving phentolamine often experience extensions of the therapeutic effects, including hypotension, orthostatic hypotension, angina, myocardial infarction, cerebrovascular accident, flushing, tachycardia, and arrhythmia all of which are related to vasodilation and decreased blood pressure. Headache, weakness, and dizziness often occur in response to hypotension. Nausea, vomiting, and diarrhea may also occur. Hypertension, wheezing, and depressed respiration would not be associated with phentolamine. The nurse should monitor for adverse effects and intervene as needed.
Question 2 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 3 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 4 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.
Question 5 of 5
Toxicity of nicotine containing products:
Correct Answer: D
Rationale: Nicotine toxicity can cause neuromuscular blockade (late phase), but atropine treats muscarinic effects, not paralysis, so that's false. It causes hypertension initially via catecholamine release, not hypotension, making that false. It harms the fetus (e.g., growth restriction), so that's incorrect. Benzodiazepines control agitation and seizures symptomatically, a true statement, useful in acute poisoning. Nausea/vomiting resolve faster than days. Benzodiazepines' symptomatic relief is a practical approach, addressing CNS overstimulation in nicotine overdose.
