Question 1 of 5
Which of the following antipsychotic agents is available in a LAI formulation that may be useful for patients with difficulty adhering to therapy?
Correct Answer: D
Rationale: Risperidone, a second-generation antipsychotic, offers a long-acting injectable (LAI) formulation (e.g., Risperdal Consta), administered every two weeks, improving adherence in schizophrenia patients with poor oral compliance. Asenapine is sublingual, not LAI. Chlorpromazine, a first-generation drug, lacks an LAI form. Clozapine, effective for treatment-resistant cases, is oral only due to agranulocytosis monitoring. Quetiapine has no LAI. Risperidone's LAI ensures steady drug levels, reducing relapse risk, making it ideal for adherence challenges, per clinical use.
Question 2 of 5
The client receives diphenhydramine (Benadryl) to control allergic symptoms. Which common symptom does the nurse teach the client to report to the physician?
Correct Answer: D
Rationale: In this scenario, the correct answer is D) Urinary hesitancy. Diphenhydramine (Benadryl) is an antihistamine that can cause anticholinergic side effects, including urinary hesitancy. This symptom is important to report to the physician because it can indicate urinary retention, which can be a serious complication. Option A) Sedation is a common side effect of diphenhydramine but is not typically a symptom that requires immediate medical attention unless it is severe and impacting daily activities. Option B) Diarrhea is not a common side effect of diphenhydramine and is unlikely to be directly related to its use. Option C) Projectile vomiting is not a common side effect of diphenhydramine and may suggest another underlying issue that needs evaluation but is not directly related to this medication. Educationally, understanding the side effects of medications is crucial for both healthcare professionals and patients to ensure safe and effective treatment. Teaching patients to recognize and report specific symptoms can help prevent complications and improve overall outcomes. It is essential for nurses to provide thorough education on medication side effects to empower patients to take an active role in their healthcare.
Question 3 of 5
The nurse administers IV magnesium sulfate to a client with preeclampsia. Which finding indicates a therapeutic effect?
Correct Answer: D
Rationale: Magnesium sulfate prevents seizures in preeclampsia via CNS depression. Absence of seizures indicates therapeutic effect, the primary goal. Decreased BP isn't magnesium's role'antihypertensives manage that. Increased urine output isn't specific. Reduced reflexes signal toxicity, not efficacy. Seizure prevention aligns with magnesium's mechanism, critical in preeclampsia where eclamptic risk is high, making D the key finding of successful therapy.
