Question 1 of 5
A hospital nurse is taking imipramine for a phobic anxiety disorder, and her patient is being treated with chlorpromazine for a psychotic disorder. Which of the following adverse effects is likely to occur in both of these individuals?
Correct Answer: C
Rationale: Imipramine (TC
A) and chlorpromazine (antipsychotic) share anticholinergic and alpha-adrenergic blocking properties. Orthostatic hypotension arises from alpha-1 receptor blockade, causing vasodilation and blood pressure drops upon standing, a common effect in both drugs, impacting patients and users alike. Excessive salivation and pupillary constriction (miosis) are cholinergic effects, opposite to their anticholinergic actions (dry mouth, mydriasis). Seizure threshold decreases with both, but this isn't an ‘adverse effect' per se—it's a risk. Weight loss isn't typical; TCAs and antipsychotics often cause gain. The shared alpha-blockade mechanism makes orthostatic hypotension a frequent, clinically significant side effect in both individuals, requiring caution in mobility and monitoring.
Question 2 of 5
The physician has prescribed sertraline (Zoloft) for the patient who is anxious and depressed. The patient calls the nurse to report that he has experienced delayed ejaculation since being on this medication. What is the best response by the nurse?
Correct Answer: A
Rationale: Sertraline, an SSRI, often causes sexual dysfunction like delayed ejaculation due to serotonin elevation. Reporting this to the doctor allows dose adjustment or switching (e.g., to bupropion), addressing quality of life.
Choice B minimizes the issue, risking noncompliance.
Choice C assumes suicide risk without basis.
Choice D falsely promises resolution. A advocates for the patient, ensuring tailored care, making it the best response.
Question 3 of 5
The student nurse is studying for a pharmacology exam and notices that many of the adrenergic blocking antagonists drugs studied in class have what suffix?
Correct Answer: B
Rationale: The suffix -lol is seen in many of the drug names for adrenergic blocking antagonists. The suffix -aine would indicate a topical anesthetic, whereas -azole indicates an antifungal, and the suffix -triptan relates to the triptans. The nurse should be familiar with drug name suffixes to aid in identifying drug classes and their therapeutic uses.
Question 4 of 5
A balanced anesthetic technique for production of general anesthesia may include which of the following drugs?
Correct Answer: D
Rationale: A balanced anesthetic technique for producing general anesthesia usually involves a combination of different types of drugs to achieve the desired level of unconsciousness, analgesia, muscle relaxation, and amnesia while minimizing adverse effects. The use of multiple drugs simultaneously allows for lower doses of each drug, reducing the risk of toxicity and adverse side effects. In a typical balanced anesthesia regimen, an inhalation anesthetic is used for the maintenance of anesthesia, a narcotic provides analgesia, a muscle relaxant is used to facilitate intubation and reduce muscle movements during surgery, and an IV barbiturate may be used as an induction agent to initiate anesthesia.
Therefore, all of the options provided - an inhalation anesthetic, a narcotic, a muscle relaxant, and an IV barbiturate - are commonly included in a balanced anesthetic technique for producing general anesthesia.
Question 5 of 5
A 42-year-old female who is obese and with a history of gallstones and cholecystitis complains of superficial skin swelling and itching. Physical examination by the primary care physician reveals skin erythema, tenderness, and swelling consistent with cellulitis. The patient is given a prescription for erythromycin. Which of the following effects must the treating physician be keenly aware of?
Correct Answer: A
Rationale: Erythromycin for cellulitis risks cholestatic jaundice , especially in patients with gallstone history. Abdominal discomfort , nausea , and vomiting (E) are common but less severe. Tinnitus is rare. Jaundice, from hepatic dysfunction, requires monitoring given her biliary background.
