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 mother asks the nurse when she should give her child cough medicine. What is the best response by the nurse?
Correct Answer: D
Rationale: Cough medicines, like dextromethorphan, suppress nonproductive (dry) coughs to aid rest, especially when sleep is disrupted . This targets symptomatic relief appropriately, avoiding overuse. Green secretions suggest infection, where suppressing cough could hinder clearance, requiring medical evaluation instead. Fever over 102°F indicates illness severity, not a cue for cough medicine alone. Bronchitis often involves productive cough, where suppressants are less suitable. The nurse's best response (
D) aligns with cough suppressants' purpose—relieving dry, disruptive coughs—ensuring safe, targeted use for the child's comfort.
Question 3 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.
Question 4 of 5
A 13-year-old boy with moderate asthma presents to the clinic for follow-up. His symptoms appear to be better controlled since adding salmeterol to his regimen. He has had to use his rescue inhaler once over the past 2 weeks during exertion. His breathing at night has improved as well. How does salmeterol exhibit its beneficial effects for asthma?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A patient has received an overdose of intravenous heparin, and is showing signs of excessive bleeding. Which substance is the antidote for heparin overdose?
Correct Answer: C
Rationale: Protamine sulfate is the antidote for heparin overdose. Heparin is an anticoagulant medication that works by inhibiting the action of thrombin and factor Xa. Protamine works by binding to heparin and neutralizing its anticoagulant effects. This helps to reverse the effects of heparin and control excessive bleeding in cases of overdose. It is important to administer protamine sulfate promptly to counteract the effects of heparin and prevent further bleeding complications. Options A, B, and D are not the correct antidotes for heparin overdose.
