NURS 5433 MODULE 4 UPDATED EXAM WITH MOST TESTED
QUESTIONS AND ANSWERS | GRADED A+ | ASSURED SUCCESS WITH
DETAILED RATIONALES
1. Which organisms are the MOST common gram-negative causes of UTI?
A. Pseudomonas, Neisseria, Salmonella
B. Serratia, H. influenzae, Shigella
C. E. coli, Klebsiella, Enterobacter, Proteus mirabilis
D. Staph aureus, Strep pyogenes, Bacillus cereus
Rationale: The vast majority of UTIs are caused by enteric gram-negative rods, especially E. coli,
with other Enterobacteriaceae close behind.
2. What is the most common gram-positive causative organism of UTI?
A. Staph aureus
B. Strep agalactiae
C. Staphylococcus saprophyticus
D. Enterococcus faecalis
Rationale: S. saprophyticus commonly causes UTIs in young sexually active women.
3. Which are risk factors for UTI? (Select all that apply)
A. High-fiber diet
B. Recent UTI
C. Recent sexual activity
D. Diabetes mellitus
E. Estrogen deficiency
F. Daily cranberry intake
Rationale: Sexual activity, urinary tract abnormalities, prior UTIs, DM, estrogen deficiency, poor
hygiene, and recent antibiotic use all increase risk.
4. What are common symptoms of uncomplicated cystitis?
,ESTUDYR
A. Flank pain, chills, sepsis
B. Dysuria, urgency, cloudy/foul urine, suprapubic tenderness
C. Marked hypertension
D. Bilateral CVA tenderness
Rationale: Lower urinary tract symptoms predominate in cystitis.
5. What finding differentiates pyelonephritis from cystitis?
A. Dysuria
B. Suprapubic tenderness
C. Fever and flank pain
D. Cloudy urine
Rationale: Systemic symptoms such as fever >101°F, chills, and flank pain strongly suggest
upper-tract involvement (pyelonephritis).
6. Which symptoms are MOST consistent with acute pyelonephritis?
A. Hematuria only
B. Dysuria only
C. Fever >101.3°F, rigors, flank pain, sepsis signs
D. Night sweats and rash
Rationale: Pyelonephritis presents with fever and systemic toxicity.
7. Why should ALL pregnant women with bacteriuria receive treatment?
A. It will always progress to sepsis
B. It causes type 1 diabetes in pregnancy
C. It increases risk of preterm labor and preeclampsia
D. It has no long-term impact
Rationale: Untreated bacteriuria increases maternal and fetal morbidity.
8. What is the MOST important diagnostic test for suspected UTI?
, ESTUDYR
A. ESR
B. CBC
C. Urine culture and sensitivity (C/S)
D. Renal biopsy
Rationale: C/S confirms organism and guides therapy.
9. The presence of WBC casts on UA indicates:
A. Cystitis
B. Bladder cancer
C. Pyelonephritis
D. Urethritis
Rationale: WBC casts signify inflammation in the renal tubules.
10. When can pyelonephritis be treated empirically before C/S results return?
A. Temperature 99°F only
B. Symptoms for <12 hours
C. Fever >101.3°F, flank pain, pyuria, hematuria
D. UA negative for WBCs
Rationale: Classic signs justify immediate broad-spectrum treatment.
11. What office test is used to screen for UTI?
A. MRI
B. CT scan
C. Urine dipstick
D. Cystoscopy
Rationale: Dipsticks detect leukocyte esterase and nitrites quickly.
12. Which dipstick findings strongly suggest infection?
