Assessment of Genitourinary System Questions
Question 1 of 5
A male patient with possible fertility problems asks the nurse where sperm is produced. The nurse knows that sperm production occurs in the:
Correct Answer: A
Rationale: The correct answer is A: Testes. Sperm production, also known as spermatogenesis, occurs in the testes specifically in the seminiferous tubules. These tubules contain specialized cells called spermatogonia that undergo a series of cell divisions to eventually form mature sperm cells. The testes also produce hormones essential for sperm production. Explanation of incorrect choices: B: Prostate - The prostate gland produces seminal fluid, not sperm. C: Epididymis - The epididymis is where sperm mature and are stored, but not where they are produced. D: Vas deferens - The vas deferens is a duct that carries sperm from the epididymis to the urethra, it does not produce sperm.
Question 2 of 5
A 35 year old man heroin addict on methadone maintenance therapy for the * last one year , is positive for TB on Chest x-ray. He was started on standard quadri anti -TB drug. He is rushed to ER complaining of withdrawal symptoms. Which of the following anti-TB drugs is likely to cause this patient's withdrawal reaction?
Correct Answer: C
Rationale: The correct answer is C: INH (Isoniazid). INH is known to interact with methadone, potentially leading to increased methadone metabolism and reduced methadone levels, causing withdrawal symptoms in a heroin addict on methadone maintenance therapy. Streptomycin (A), Rifampicin (B), and Pyrazinamide (D) are not associated with causing withdrawal symptoms in this scenario. Streptomycin can cause hearing loss and kidney damage, Rifampicin can cause liver toxicity and drug interactions, and Pyrazinamide can cause liver toxicity and joint pain.
Question 3 of 5
This class of drug exert its antimicrobial action by binding to 30S ribosomes * and inhibit bacterial protein synthesis, is the drug of choice for treating non- gonoccocal urethritis caused by Chlamydia and Ureaplasma, but should be avoided in patients with liver disease:
Correct Answer: D
Rationale: The correct answer is D: Tetracyclines. Tetracyclines bind to the 30S ribosomal subunit and inhibit bacterial protein synthesis, making them effective against Chlamydia and Ureaplasma causing non-gonococcal urethritis. They should be avoided in patients with liver disease due to the potential for hepatotoxicity. A: Daptomycin is not the correct choice as it works by disrupting bacterial cell membrane function, not by binding to ribosomes. B: Carbapenems are broad-spectrum antibiotics that inhibit cell wall synthesis by binding to penicillin-binding proteins, not ribosomes. C: Cephalosporins are beta-lactam antibiotics that inhibit cell wall synthesis, not protein synthesis by binding to ribosomes. In summary, tetracyclines are the drug of choice for the given condition due to their mechanism of action on ribosomes, while the other choices are incorrect as they target different
Question 4 of 5
A 20 year old patient presented to the ER with headache, stiff neck and fever * for 3 days and is diagnosed with bacterial meningitis. Which one of the following antibiotics is the best choice to treat meningitis?
Correct Answer: C
Rationale: The correct answer is C: Cefotaxime. This third-generation cephalosporin is a preferred choice for treating bacterial meningitis due to its broad-spectrum coverage against common pathogens causing meningitis, including Streptococcus pneumoniae and Neisseria meningitidis. Cefuroxime (A) and Cephalexin (B) are not optimal choices as they have less activity against these pathogens. Cefdinir (D) is not a recommended treatment for bacterial meningitis and is not as effective as Cefotaxime in this scenario.
Question 5 of 5
What is the drug of choice for ringworm infection ?: *
Correct Answer: A
Rationale: The correct answer is A: Griseofulvin. Griseofulvin is the drug of choice for ringworm infections due to its effectiveness against dermatophytes. It works by inhibiting fungal cell division. Amphotericin B is used for systemic fungal infections, not ringworm. Nystatin is used for yeast infections, not ringworm. Neomycin is an antibiotic and is not effective against fungal infections like ringworm.
