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
A 22-year-old man college student does poorly on a course examination and decides to attempt suicide. He finds a bottle of barbiturates in his mother's medicine cabinet. He takes 2 of the 30 pills in the bottle. Which of the following effects is most likely to be exhibited by the patient?
Correct Answer: D
Rationale: Two barbiturate pills (low dose) likely cause sedation . Barbiturates depress CNS; small amounts induce sleepiness, not anesthesia , coma , or death . Hypnosis (E) overlaps but sedation fits best. This reflects a subtherapeutic overdose attempt.
Question 3 of 5
A patient says, 'I have such bad seasonal allergies. Is there anything I can take to keep them from happening?' What information should the nurse provide?
Correct Answer: C
Rationale: Mast cell stabilizers prevent histamine release . Decongestants relieve, not prevent. C offers proactive prevention, making it key.
Question 4 of 5
A patient has taken two doses of interferon Alfa-2b (Intron-A). He comes to the clinic today with the following complaints. Which symptoms would the nurse identify as common adverse effects of this therapy?
Correct Answer: A
Rationale: Interferon Alfa-2b is an immunomodulatory drug used for conditions like hepatitis or cancer, known for causing flu-like symptoms and systemic effects. Common adverse effects include dizziness, fatigue, and anorexia (loss of appetite), as listed in the correct answer (1, 3, 4). Dizziness reflects the drug's impact on the central nervous system, often reported early in therapy. Loss of appetite and fatigue are also hallmark symptoms due to interferon's influence on metabolism and energy levels. An itchy rash , while possible as a hypersensitivity reaction, is less commonly associated with interferon compared to these systemic effects. The nurse must recognize these as expected side effects, distinguishing them from severe reactions requiring intervention. Since the question asks for common adverse effects and the correct answer includes multiple symptoms, choice A (dizziness) is a key identifier among them, supported by its prevalence in clinical use, making it the primary focus here.
Question 5 of 5
A patient complains of night blindness. The nurse correctly recommends which foods?
Correct Answer: B
Rationale: Night blindness is often caused by vitamin A deficiency. Foods rich in vitamin A, such as fortified milk and eggs, are recommended. Skim milk and peas (A), nuts and yeast (C), and enriched breads and cereals (D) are not significant sources of vitamin A.
