Question 1 of 5
Which statement is accurate concerning the use of aspirin (ASA) to treat pain?
Correct Answer: B
Rationale: Aspirin's use for pain involves anti-inflammatory and analgesic properties, but it risks GI irritation. Enteric-coated capsules minimize this by dissolving in the intestine, not the stomach, reducing bleeding risk—an accurate statement. High doses are true for anticoagulation, not pain relief, where lower doses suffice. Herbs like garlic and ginger increase bleeding risk, not inflammation relief, making it dangerous advice. Low doses (choice D, 325 mg) primarily prevent clotting, not significantly reduce inflammation, which requires higher doses. Choice B correctly reflects a practical measure to enhance aspirin's safety profile for pain management.
Question 2 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.
Question 3 of 5
Mark the location of the beginning of the plateau phase on this dose-response relationship curve.
Correct Answer: D
Rationale: The plateau phase, where max effect holds despite dose increases, is the curve's top horizontal stretch, per pharmacodynamic curves. Beginning is pre-effect. Upward move is onset. Mid-upstroke is rising. Plateau marks saturation, standard in graphs.
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
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.
