Question 1 of 5
The drug that will most likely be used for treatment of erectile dysfunction (ED) is
Correct Answer: D
Rationale: Sildenafil (Viagra), a phosphodiesterase-5 inhibitor, enhances penile blood flow by increasing cyclic GMP, directly treating erectile dysfunction (ED) and is the standard first-line therapy. Leuprolide, a GnRH agonist, suppresses testosterone for prostate cancer, potentially worsening ED. Finasteride, for benign prostatic hyperplasia (BPH), reduces prostate size but may cause ED as a side effect, not treat it. Tamsulosin, an alpha-blocker for BPH, improves urinary flow but isn't indicated for ED and can lower blood pressure. Sildenafil's targeted action on vascular mechanisms in ED distinguishes it, offering rapid efficacy and a well-established safety profile for this condition.
Question 2 of 5
The patient tells the nurse he worries about everything all day, feels confused, restless, and just can't stop worrying. What is the best response by the nurse?
Correct Answer: A
Rationale: Persistent worry, confusion, and restlessness suggest generalized anxiety disorder (GAD)-relaxation techniques (e.g., breathing) help manage, a practical response. Social anxiety ties to specific triggers, not all-day worry. PTSD needs trauma history, not indicated. Panic disorder features acute attacks, not constant worry. GAD diagnosis with techniques fits symptoms, per psychiatry.

Question 4 of 5
A 33-year-old female is brought to the emergency department by her mother. The patient had a sudden onset of fever and her temperature is now 40°C (104°F). She has no sick contacts. The mother mentions that she is on a medication for schizophrenia but could not remember the name. A complete blood count shows 250 neutrophils per microliter. Which of the following medications is she likely taking?
Correct Answer: A
Rationale: Fever and severe neutropenia (250 neutrophils/μL) in a schizophrenic patient suggest clozapine . Clozapine causes agranulocytosis, a rare but serious side effect requiring monitoring. Olanzapine , Quetiapine , Risperidone , and Haloperidol (E) rarely cause this. Clozapine's risk explains the acute presentation, necessitating immediate cessation.
Question 5 of 5
A 22-year-old woman is interested in taking oral contraceptives for the prevention of pregnancy. The most likely benefit in terms of disease prevention from oral contraceptives is which of the following?

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
