ATI VATI Pharmacology Assessment Questions
Question 1 of 5
The primary function of luteinizing hormone (LH) in men is to
Correct Answer: D
Rationale: Luteinizing hormone (LH) from the pituitary stimulates testosterone production in testicular Leydig cells, its primary role in men, driving male physiology. Sperm production is regulated by FSH, not LH. Secondary sex characteristics and sex organ growth depend on testosterone, which LH indirectly supports by controlling its synthesis, not directly managing. Testosterone regulation is LH's specific function, triggering steroidogenesis, essential for fertility and masculinity, distinct from FSH's gamete role.
Question 2 of 5
The most productive way of managing stress would be to
Correct Answer: A
Rationale: Combining drugs (e.g., benzos) with nonpharmacological methods (e.g., meditation) balances quick relief and long-term coping, per stress management best practices. Anxiolytics alone risk dependence. Meditation helps but may not suffice. Addressing the cause is ideal but often slow-combined approach leverages both, enhancing outcomes.
Question 3 of 5
A 52-year-old overweight male steamroller operator presents to his primary care physician complaining of itchy, watery eyes and runny nose in the springtime. He says that he has had this problem for as long as he can remember but does not like going to doctors. His wife finally convinced him to come today to see what his physician might be able to do for him. What is the most appropriate treatment for this patient?
Correct Answer: D
Rationale: The patient's chronic springtime symptoms-itchy, watery eyes, and runny nose-point to seasonal allergic rhinitis, a histamine-driven condition. Albuterol is a bronchodilator for asthma, not allergies. Diphenhydramine is an H1 antihistamine, effective but sedating, which may not suit an active steamroller operator. Epinephrine is for acute anaphylaxis, not chronic allergies. Hydroxyzine is another sedating antihistamine, less ideal for daily use. Loratadine (E), a non-sedating H1 antihistamine, effectively blocks histamine receptors, relieving symptoms without drowsiness, making it the most appropriate choice. Given his occupation and chronicity, a non-sedating option is critical for safety and compliance. Loratadine's long-acting, once-daily dosing also fits his reluctance to seek medical care, offering convenience and efficacy. The rationale prioritizes a treatment balancing symptom relief with minimal impact on his daily function, ruling out sedating or irrelevant options.
