ATI Pharmacology Practice Exam B Questions
Question 1 of 5
An 18-year-old male is being evaluated for hypogonadism. The nurse would evaluate which physical findings as supporting that tentative diagnosis?
Correct Answer: A
Rationale: Hypogonadism in males, marked by low testosterone, delays secondary sexual characteristics, like facial hair, which remains minimal, soft, and light due to insufficient androgen stimulation of follicles. Absent pubic hair aligns with this, reflecting poor pubertal development from gonadal dysfunction. Decreased subcutaneous fat is less typical-hypogonadism often increases fat due to estrogen dominance from low testosterone. Small testicles directly indicate testicular failure, a hallmark of primary hypogonadism, reducing hormone and sperm output. Minimal facial hair is a visible, assessable sign tied to androgen deficiency, distinguishing it from normal variation, and supports the diagnosis alongside other findings like testicular size, reflecting the condition's impact on masculinization and reproductive maturity.
Question 2 of 5
A woman who wishes to become pregnant is concerned about the drugs she must take in order to treat a serious medical condition. The nurse reviewing the drug list would be most concerned about which kind of drug?
Correct Answer: A
Rationale: Long half-life drugs (e.g., diazepam) linger, risking fetal exposure post-conception, a pharmacokinetic worry for serious conditions. No active metabolites reduce risk. High protein-binding limits free drug, less concern. As-needed use minimizes exposure. Long half-life heightens teratogenic potential, critical in planning.
Question 3 of 5
The client has osteomalacia, and the physician has ordered a treatment to restore calcium balance. What will the nurse plan to administer to the client?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
An 18-year-old woman presents to her primary care physician after experiencing a one-sided headache for the fourth time in the last 2 years. Her headaches have all been similar in nature. She says the pain is worst right behind her eye and that she feels nauseous and cannot stand bright lights or loud noises while she is having a headache. The physician prescribes sumatriptan. What is the mechanism of action of this medication?
Correct Answer: B
Rationale: Migraine symptoms (unilateral pain, photophobia, nausea) respond to sumatriptan, a 5-HT1B/1D agonist. Option , blocking serotonin-mediated nociceptive signaling, is correct-sumatriptan constricts cranial vessels and inhibits trigeminal pain pathways. Option , COX blockade, is NSAIDs' mechanism. Option , prostaglandin synthesis, is similar. Options and (E), opioid receptor stimulation, are unrelated. Sumatriptan's serotonin action targets migraine-specific pathophysiology, relieving this patient's symptoms.
Question 5 of 5
A 31-year-old woman smoker expresses a desire to quit smoking. She has a 10 pack-year history of smoking but no other health issues. She wants to try varenicline, a drug she recently heard about, to help her quit. Which of the following side effects of varenicline is she most likely to encounter?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
