Question 1 of 5
The urinary bladder:
Correct Answer: D
Rationale: The bladder lies posterior to the pubic symphysis (D), a key anatomical position. It has smooth muscle (detrusor), not skeletal (A), connects to the urethra, not ureter (B), and is innervated by pelvic nerves, not cranial XI (C), making D the correct feature.
Question 2 of 5
Which of the following would NOT be secreted from the ISF into the filtrate?
Correct Answer: B
Rationale: Amino acids (B) are reabsorbed in the PCT, not secreted, to conserve nutrients. Organic acids (A), bases (C), and creatinine (D) are secreted to eliminate waste, making B the exception.
Question 3 of 5
Following rectal surgery, a patient voids about 50 mL of urine every 30 to 60 minutes. Which nursing action is most appropriate?
Correct Answer: A
Rationale: Frequent small voids suggest overflow incontinence post-surgery, so checking residual urine with ultrasound (A) assesses bladder emptying. Monitoring I&O (B) delays intervention, fluids (C) don't address retention, and reassurance (D) ignores the issue, making A most appropriate.
Question 4 of 5
Which information noted by the nurse when caring for a patient with a bladder infection is most important to report to the health care provider?
Correct Answer: C
Rationale: Flank pain (C) in a bladder infection suggests pyelonephritis, a complication needing prompt reporting. Dysuria (A), hematuria (B), and mild fever (D) are typical, but upper tract involvement is urgent, making C most important.
Question 5 of 5
Which statement by a patient who had a cystoscopy the previous day should the nurse report immediately to the health care provider?
Correct Answer: D
Rationale: The patient's elevated temperature may indicate a bladder infection, a possible complication of cystoscopy. The health care provider should be notified so that antibiotic therapy can be started. Pink-tinged urine is expected after a cystoscopy. The insomnia and bruising should be discussed further with the patient but do not indicate a need to notify the health care provider.
