Assessment of Genitourinary System Questions
Question 1 of 5
What volume of glomerular filtrate do adults within the urinary system? make every day?
Correct Answer: B
Rationale: The correct answer is B: 1-5 litres. This is the average volume of glomerular filtrate that adults produce daily. The kidneys filter around 180 liters of blood plasma daily, but only 1-5 liters of urine is excreted. The gall bladder (A) stores bile, not involved in urine production. The ureter (C) is a tube that carries urine from the kidney to the bladder, doesn't relate to the volume of filtrate. 80 liters (D) is too high for daily urine production and would lead to severe dehydration.
Question 2 of 5
Which is incorrect regarding CAPD peritonitis?
Correct Answer: C
Rationale: The correct answer is C because vancomycin as a one-off 2 grams to CAPD bags is not sufficient for proven gram-positive infection. For CAPD peritonitis, continuous intraperitoneal antibiotics are required, not just a single dose. This is because peritoneal dialysis fluid is continuously present in the peritoneal cavity, necessitating ongoing antibiotic therapy. Choice A is incorrect because a positive Gram stain in only 10-40% of culture-positive bags does not rule out peritonitis. Choice B is incorrect as coagulase-negative staphylococci are the most common organisms isolated in CAPD peritonitis, not Staph aureus. Choice D is incorrect as antibiotics are usually needed parenterally in addition to intraperitoneal administration for severe cases or systemic infections.
Question 3 of 5
Which of these statements is true regarding the penis?
Correct Answer: D
Rationale: The correct answer is D because the corpus spongiosum is a column of erectile tissue in the penis that surrounds the urethra and expands into the glans. This expansion forms the glans, which is the rounded tip of the penis. This is anatomically accurate as the glans is indeed an expanded cone-shaped structure at the distal end of the penis. A: The urethral meatus is actually located at the tip of the glans, which is at the distal end of the penis, not the ventral side. B: The prepuce is the foreskin that covers the glans, not the shaft of the penis. C: The penis is actually made up of three cylindrical columns of erectile tissue - two corpora cavernosa and one corpus spongiosum.
Question 4 of 5
The nurse is examining the glans and knows which finding is normal for this area?
Correct Answer: D
Rationale: The correct answer is D because the glans normally has wrinkled skin without lesions. This is due to the presence of sebaceous glands on the glans, which can create a wrinkled appearance. Choice A is incorrect as discharge from the meatus is not a normal finding. Choice B is incomplete. Choice C is irrelevant as the presence of pests is not related to the appearance of the glans. Thus, the wrinkled skin without lesions is the correct and normal finding for the glans during examination.
Question 5 of 5
The nurse knows that a common assessment finding in a boy younger than 2 years old is:
Correct Answer: D
Rationale: The correct answer is D because it is a common assessment finding in boys younger than 2 years old to have a penis that looks large in relation to the scrotum due to the immaturity of the genitourinary system. This is known as physiological phimosis, where the foreskin cannot be retracted. Choices A and C are incorrect as inflamed and tender spermatic cord and presence of a hernia are not common assessment findings in boys younger than 2 years old.
