ATI Pharmacology Online Practice 2023 A Questions
Question 1 of 5
A patient in the clinic reports difficulty tolerating the current ACE inhibitor medication, and questions if another medication could be used. The nurse correctly suspects the prescriber will choose which medication, which affects the renin-angiotensin-aldosterone system?
Correct Answer: B
Rationale: Losartan is an angiotensin II receptor blocker (ARB) that affects the renin-angiotensin-aldosterone system (RAAS) and is often used as an alternative to ACE inhibitors. Atenolol (A) is a beta-blocker, spironolactone (C) is a potassium-sparing diuretic, and adenosine (D) is used for arrhythmias. ARBs like losartan are preferred for patients who cannot tolerate ACE inhibitors due to side effects like cough or angioedema.
Question 2 of 5
Which instruction(s) will the nurse include when teaching patients about gentamicin? (Select all that apply.)
Correct Answer: A
Rationale: Gentamicin is an aminoglycoside antibiotic associated with ototoxicity, which can manifest as hearing loss or tinnitus. Patients should be instructed to report any changes in hearing. Sunscreen is not specifically required for gentamicin, as it does not cause photosensitivity. Intravenous gentamicin is typically infused over 30-60 minutes, not 20 minutes. Monitoring for mouth ulcers and vaginitis is not a priority with gentamicin, but renal function and ototoxicity should be closely monitored.
Question 3 of 5
A patient is mowing his lawn on a hot Saturday afternoon. He begins to notice chest pain. What should his first action be?
Correct Answer: B
Rationale: The patient's first action should be to stop mowing and sit or lie down. Chest pain can be a symptom of a heart attack, and it is important for the patient to immediately rest and avoid physical strain. Continuing to mow the lawn could worsen the condition or lead to further complications. Sitting or lying down will help reduce the heart's workload and minimize the exertion on the body. If the chest pain continues or worsens, seeking medical help should be the next course of action.
Question 4 of 5
Regarding drugs used in the treatment of status epilepsy:
Correct Answer: D
Rationale: Phenytoin controls status epilepticus via anticonvulsant action, not sedation, so that's false. It precipitates in dextrose, only saline-compatible, making that false. Diazepam's effect is short-lived, not long-lasting, so that's incorrect. Phenobarbitone commonly causes respiratory depression, a true statement, due to CNS suppression. Phenytoin's rate is 50 mg/min max. This side effect limits phenobarbitone's use, requiring ventilatory support in status management.
Question 5 of 5
The nurse is teaching a class for clients about over-the-counter (OTC) medications. The nurse determines that education has been effective when the clients make which statement?
Correct Answer: C
Rationale: Reading OTC labels and seeking clarification from a doctor if unclear ensures safe use, reflecting effective education on responsibility. Always calling the doctor is overly cautious-OTC drugs are for self-management. Pharmacists help, but label-reading is primary. Assuming OTC safety ignores risks like ibuprofen's bleeding potential. Label focus empowers clients, balancing autonomy with safety, a key learning outcome.
