Question 1 of 5
Allopurinol (Zyloprim) is prescribed for a client for the treatment of gout. And the nurse is providing medication instructions. The nurse tells the client to?
Correct Answer: B
Rationale: Allopurinol should be taken with food to reduce gastrointestinal irritation. Limiting vitamin C intake is advised because it can increase uric acid levels, counteracting the drug's effects. A rash is not a normal side effect and may indicate a hypersensitivity reaction, requiring immediate medical attention. The therapeutic effects of allopurinol are not immediate and may take weeks to become apparent. Proper patient education is essential to ensure adherence and safety.
Question 2 of 5
The physician has prescribed haloperidol (Haldol) for the patient with schizophrenia. What is the priority patient outcome?
Correct Answer: B
Rationale: Haloperidol, a conventional antipsychotic, treats schizophrenia by reducing positive symptoms like hallucinations, but its efficacy depends on adherence. The priority outcome is medication compliance, as relapse is common without consistent use, undermining all other goals. Adequate fluids and fiber mitigate side effects (e.g., constipation) but are secondary to ensuring treatment continuity. Decreased hallucinations is a desired effect, not an outcome ensuring it happens. Restlessness indicates side effects (e.g., akathisia), not a goal. Compliance is foundational, as schizophrenia's chronic nature requires long-term management, making choice B the nurse's primary focus for successful therapy.
Question 3 of 5
A 52-year-old woman with a history of recurrent urinary tract infections complains of easy bruising as well as chronic fatigue. She is maintained on daily antibiotic prophylaxis with trimethoprim. Which of the following hematologic effects is likely as a result of long-term therapy with trimethoprim?
Correct Answer: B
Rationale: Trimethoprim's folate antagonism with long-term use causes megaloblastic anemia . Bruising and fatigue reflect impaired erythropoiesis. Aplastic anemia , microcytic , normocytic , and pernicious (E) don't fit. This reversible effect requires folate supplementation.
Question 4 of 5
For which serious adverse effect should the nurse closely monitor a patient who is taking lincosamides?
Correct Answer: D
Rationale: Lincosamides, such as clindamycin, are associated with a high risk of Clostridium difficile-associated diarrhea (CDAD), a potentially life-threatening condition. CDAD occurs due to the disruption of normal gut flora, allowing C. difficile to overgrow and produce toxins. Symptoms include severe diarrhea, abdominal pain, and fever. While lincosamides can rarely cause hepatotoxicity or ototoxicity, CDAD is the most common and serious adverse effect. Seizures are not typically associated with lincosamides. Early identification and treatment of CDAD are crucial to prevent complications like toxic megacolon or sepsis.
Question 5 of 5
Drugs may be excreted by any route in the body, except:
Correct Answer: D
Rationale: Saliva is not a common route for drug excretion. Drugs are primarily excreted from the body through various routes such as the kidneys (urine), lungs (exhaled air), gastrointestinal tract (feces), and tears (through the eyes). Saliva does not play a major role in drug excretion, as most drugs are not significantly eliminated through saliva.
