ATI Pharmacology The Respiratory System Quizlet Questions
Question 1 of 5
The nurse is caring for a client receiving amitriptyline (Elavil) for depression. Which assessment finding requires immediate attention?
Correct Answer: C
Rationale: Amitriptyline, a tricyclic antidepressant, has anticholinergic effects, including urinary retention , a medical emergency risking bladder damage or infection, needing immediate intervention. Dry mouth and constipation are common, manageable side effects. Drowsiness is expected with its sedative action. Urinary retention's severity'potential for acute retention'sets it apart, requiring rapid reporting or catheterization. This aligns with amitriptyline's blockade of muscarinic receptors, where bladder dysfunction can escalate fast, making C the finding demanding urgent attention over chronic annoyances.
Question 2 of 5
The client receives estrogen for prostate cancer. He asks the nurse why he is receiving a female hormone. What is the best response by the nurse?
Correct Answer: C
Rationale: Prostate cancer is androgen-dependent, relying on testosterone and other androgens for growth. Estrogen therapy suppresses pituitary secretion of luteinizing hormone, reducing testicular androgen production, effectively starving the cancer. This hormonal manipulation is a standard approach.
Choice A inaccurately suggests direct cell death, not estrogen's mechanism.
Choice B overstates testosterone elimination; it's reduced, not eradicated.
Choice D misattributes nutrient blockade, unrelated to estrogen's action. The nurse's best response (
C) clarifies estrogen's role in androgen suppression, addressing the client's confusion with precision and relevance to his treatment.
Question 3 of 5
A patient with a known history of angina was walking his dog and developed chest pain. The patient immediately stops walking and sits down. He continues to experience chest pain when sitting down. When should he call 911?
Correct Answer: A
Rationale: A patient with a known history of angina who experiences chest pain while walking, which persists even when sitting down, should call 911 immediately. This is indicative of unstable angina, which can progress to a heart attack (myocardial infarction). Given the potential seriousness of the situation, prompt medical attention is warranted to evaluate and manage the condition effectively. It is crucial not to delay in seeking emergency help when experiencing such symptoms, even if the pain might seem to improve temporarily or persist at a certain level.
Question 4 of 5
What classification of drug is Penicillin?
Correct Answer: C
Rationale: Penicillin is classified as an antibiotic drug, specifically an antibacterial agent. It is used to treat various bacterial infections by inhibiting the growth of bacteria or killing them directly.
Therefore, it is not categorized as an antiarrhythmic, anticonvulsant, or mood stabilizer. Instead, Penicillin falls under the classification of drugs that are effective against bacterial infections, making it an "anti-ineffective" drug.
Question 5 of 5
Which of the following cytotoxic drugs is least likely to cause emesis during chemotherapy?
Correct Answer: D
Rationale: Emesis risk depends on chemotherapeutic emetogenicity. Cisplatin, dacarbazine, doxorubicin, and mustine are highly emetogenic, triggering vomiting via chemoreceptor zones. Vincristine, a vinca alkaloid, is least emetogenic, causing neuropathy instead, making it the exception. This lower risk reduces antiemetic needs, easing patient burden during treatment.
