SECTION 1: RENAL & URINARY SYSTEM PATHOPHYSIOLOGY
Question 1
Which of the following can help to prevent a urinary tract infection (UTI)?
A) Decreasing water consumption
B) Increasing water consumption
C) Avoiding acidic foods
D) Taking prophylactic antibiotics daily
Correct Answer: B
Rationale: Water consumption prevents UTIs by keeping bacteria flushed out of the
urinary tract . Adequate hydration dilutes urine and promotes frequent voiding, which
helps eliminate bacteria from the bladder and urethra before colonization can occur.
,Question 2
Which of the following is true regarding a complicated urinary tract infection?
A) A complicated UTI responds well to a single dose of antibiotics
B) A complicated UTI can be caused by a structural issue in the urinary tract
C) A complicated UTI is always associated with pregnancy
D) A complicated UTI only occurs in men
Correct Answer: B
Rationale: A complicated UTI can be caused by a structural issue in the urinary tract .
Structural abnormalities, urinary obstruction, indwelling catheters, or functional
abnormalities (e.g., neurogenic bladder) increase the risk of UTIs that are more difficult
to treat and more likely to recur.
Question 3
A symptom of a lower urinary tract infection includes:
A) Fever
B) Urgency
C) Flank pain
D) Chills
Correct Answer: B
Rationale: Urgency is a symptom of lower tract UTI . Lower UTIs (cystitis, urethritis)
typically present with local symptoms including urgency, frequency, dysuria, and
suprapubic discomfort. Fever and flank pain indicate upper tract involvement
(pyelonephritis).
Question 4
Women are at a higher risk for the development of a UTI because of having:
A) A longer urethra
B) A shorter urethra
C) A more acidic urine pH
D) Higher estrogen levels
, Correct Answer: B
Rationale: Women are at a higher risk for the development of a UTI because of having a
shorter urethra . The shorter female urethra allows bacteria from the perineal area to
more easily reach the bladder, increasing susceptibility to ascending infection.
Question 5
Which of the following is a risk factor for the development of a urinary tract infection
(UTI)?
A) Pregnancy
B) Hypertension
C) Hyperthyroidism
D) Physical activity
Correct Answer: A
Rationale: Pregnancy is a risk factor for the development of a UTI . During pregnancy,
progesterone relaxes smooth muscle causing urinary stasis, allowing bacteria to
colonize. The shorter female urethra and mechanical pressure from the growing uterus
also contribute to increased UTI risk.
Question 6
The presence of nitrites on a urine dipstick indicates that the causative bacteria is:
A) Gram-positive
B) Gram-negative
C) Fungal
D) Viral
Correct Answer: B
Rationale: The presence of nitrites indicates that the causative bacteria is gram-
negative . Gram-negative bacteria (particularly E. coli) produce nitrate reductase, which
converts dietary nitrates to nitrites. This test is highly specific for bacterial infection.
