ATI Pharmacology Assessment 2 Questions
Question 1 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.
Question 2 of 5
A drug has been prescribed to decrease the effects of an endogenous chemical. The nurse would place this drug in which category?
Correct Answer: C
Rationale: Antagonists block endogenous chemicals' effects (e.g., beta-blockers vs. adrenaline), reducing activity. Agonists mimic, partial agonists partially activate, and agonist-antagonists mix effects. Decreasing an endogenous effect fits antagonists, a pharmacodynamic classification.
Question 3 of 5
The patient has been depressed, and the physician plans to begin treatment with an antidepressant medication. In performing the initial assessment, what is the most important question for the nurse to ask?
Correct Answer: D
Rationale: Suicide risk is critical in depression-antidepressants may increase it early (e.g., energy before mood lifts), per black box warnings. Alcohol use, allergies, and duration matter but aren't immediate life threats. Suicidal thoughts guide urgent intervention, per psychiatric priority.
Question 4 of 5
A 21-year-old male presents to the clinic with 6 weeks of painful, bloody stools. Flexible sigmoidoscopy reveals erythema and friability with pseudopolyps. Which of the following drugs used for ulcerative colitis has both anti-inflammatory and antibacterial properties?
Correct Answer: C
Rationale: Ulcerative colitis (UC) presents with bloody stools and mucosal inflammation, as seen on sigmoidoscopy. Sulfasalazine is correct-it combines 5-ASA (anti-inflammatory) and sulfapyridine (antibacterial), reducing inflammation and bacterial overgrowth in UC. Azathioprine is an immunosuppressant, lacking antibacterial action. Cyclosporine is immunosuppressive, not antibacterial. Mesalamine is anti-inflammatory only. Olsalazine (E) is similar to mesalamine. Sulfasalazine's dual action targets UC's inflammatory and microbial components, making it uniquely suited among the options for this chronic condition.
Question 5 of 5
A 48-year-old man presents to the emergency department in the morning with urticaria and difficulty breathing following a bee sting received while gardening. He is treated, recovers, and is sent home. Later that evening, his symptoms return and he is treated again in the emergency department. He denies having been stung again. What should have been given to this patient to avoid his return to the emergency department?
Correct Answer: D
Rationale: Recurrent allergic symptoms post-bee sting suggest ongoing inflammation. Prednisolone , a corticosteroid, reduces late-phase reactions. Diphenhydramine and Loratadine treat acute symptoms. Epinephrine is for anaphylaxis but short-acting. Prednisolone prevents biphasic reactions, avoiding his return.
