400 ACTUAL QUESTIONS AND RATIONALE ALREADY
GRADED A+ NEW!!!!!!!!!!!!!!!
This comprehensive 400-question review covers NSG 530 Advanced
Pathophysiology Exam 3 content in its entirety, focusing on gastrointestinal,
renal, and reproductive pathophysiology. It addresses cellular adaptation,
fluid and electrolyte balance, acid-base disorders, inflammation, and
immunity. The questions thoroughly examine acute pancreatitis, cirrhosis,
hepatic encephalopathy, GERD, pyloric stenosis, and intussusception. Renal
coverage includes acute kidney injury, nephrotic and nephritic syndromes,
pyelonephritis, glomerulonephritis, nephrolithiasis, and congenital anomalies
like horseshoe kidney and Potter syndrome. Reproductive topics span PCOS,
endometriosis, dysmenorrhea, amenorrhea, breast cancer, testicular cancer,
BPH, prostate cancer, and STIs, providing complete preparation for
advanced pathophysiology examination.
1. A 3-year-old child presents with nausea, vomiting, and diarrhea. The child
attends a daycare and has not been vaccinated. There is no other significant history,
and his parents are healthy. Which diagnosis is supported by these symptoms?
A. Hepatitis A
B. Hepatitis B
C. Hepatitis C
D. Cirrhosis
Answer: A
Rationale: Hepatitis A is a highly contagious liver infection caused by the hepatitis
A virus. It is commonly transmitted through the fecal-oral route, which is typical in
daycare settings where children are not yet fully toilet trained. The lack of
vaccination increases susceptibility. Hepatitis B and C are transmitted through
blood and body fluids, not typically through daycare exposure, and cirrhosis is a
chronic condition, not an acute presentation.
,2. A premature infant has abdominal distention, pain, fever, bradycardia, and
apnea. Stools are bloody, and white blood cells are elevated. What diagnosis do
these symptoms support?
A. Failure to thrive
B. Marasmus
C. Necrotizing enterocolitis
D. Celiac sprue
Answer: C
Rationale: Necrotizing enterocolitis (NEC) is a serious gastrointestinal disease that
primarily affects premature infants. The classic presentation includes abdominal
distention, feeding intolerance, bloody stools, and systemic signs such as fever,
bradycardia, and apnea. Elevated white blood cells indicate infection and
inflammation. Failure to thrive and marasmus are general malnutrition states, and
celiac sprue is a gluten intolerance that presents later in life.
3. Which statement is TRUE regarding breast cancer?
A. The older the age at a woman's first childbirth, the lower the risk.
B. It is the second most common cause of cancer in women.
C. The incidence has been declining since 1955.
D. Hispanic women have the highest mortality rate.
Answer: D
Rationale: Research indicates that Hispanic women have a higher mortality rate
from breast cancer compared to other ethnic groups. Early age at first childbirth is
associated with lower risk, not higher. Breast cancer is the most common cancer in
women (excluding skin cancer), and its incidence has not been declining since
1955.
4. Which of the following is TRUE regarding childhood diarrhea?
A. It occurs 3-5 times during the first 3 years of life.
B. Most episodes resolve within 24 hours.
C. Infant diarrhea may be a congenital or metabolic anomaly.
D. It is the second leading cause of death in children under 5 years old.
Answer: C
Rationale: In infants, diarrhea can be a symptom of a congenital or metabolic
anomaly, such as congenital chloride diarrhea or metabolic disorders. While
diarrhea is common, it does not occur a specific number of times, and episodes can
last longer than 24 hours. It is a leading cause of death globally, but not
specifically the second leading cause.
5. A patient is experiencing diuresis. Which statement is an accurate explanation?
,A. Increase in renin
B. Increase in aldosterone
C. Increase in antidiuretic hormone
D. Increase in atrial natriuretic peptide
Answer: D
Rationale: Atrial natriuretic peptide (ANP) is a hormone released by the heart in
response to increased blood volume and pressure. ANP promotes diuresis
(increased urine production) by increasing glomerular filtration rate and inhibiting
sodium reabsorption in the kidneys. Renin, aldosterone, and ADH all promote fluid
retention, not diuresis.
6. Which of the following, found in the liver sinusoids, are important for healing
liver injury and are bactericidal?
A. Hepatocytes
B. Liver lobules
C. Kupffer cells
D. Disse space
Answer: C
Rationale: Kupffer cells are specialized macrophages located in the liver sinusoids.
They are part of the reticuloendothelial system and play a critical role in the liver's
immune response. They are responsible for phagocytosing pathogens (bactericidal
function) and debris, and they release cytokines that promote tissue repair and
healing after liver injury. Hepatocytes are the functional liver cells, lobules are
structural units, and the Disse space is the perisinusoidal space.
7. A female patient undergoes a gastric resection. Following surgery, she
experiences intermittent severe pain and epigastric fullness after eating. Which of
the following is the most likely reason for her symptoms?
A. Diarrhea
B. Dumping
C. Alkaline
D. Afferent loop obstruction
Answer: D
Rationale: Afferent loop obstruction is a complication of Billroth II gastrectomy
where the afferent loop (duodenum) becomes obstructed. This leads to a buildup of
bile and pancreatic secretions, causing intermittent severe epigastric pain, fullness,
and nausea, often after eating. Dumping syndrome causes rapid gastric emptying
and systemic symptoms like dizziness and sweating. Alkaline reflux causes
heartburn, and diarrhea is a nonspecific symptom.
, 8. A patient presents with flank pain and anuria followed by polyuria after
undergoing catheterization of the ureters. What is the most likely cause of this
condition?
A. Acute tubular necrosis
B. Prerenal acute kidney injury
C. Postrenal acute kidney injury
D. Infrarenal acute kidney injury
Answer: C
Rationale: Postrenal acute kidney injury is caused by an obstruction of urine flow
from the kidneys. The presentation of flank pain, anuria (no urine output), followed
by polyuria (excessive urine) after ureteral catheterization indicates a postrenal
obstruction that was relieved by the catheter. This is a classic pattern for postrenal
AKI. Prerenal and intrarenal causes do not present with this obstructive pattern.
9. Which statement regarding renal cell carcinoma is correct?
A. It is associated with p53.
B. Symptoms include painless hematuria.
C. Early stages produce a large abdominal mass.
D. Granular cell tumors have a better prognosis.
Answer: B
Rationale: Renal cell carcinoma (RCC) is a malignant tumor of the kidney that
often presents with painless hematuria (blood in the urine). It is associated with the
VHL gene, not p53. Early stages do not typically produce a large abdominal mass,
and the prognosis is generally poor for granular cell tumors.
10. A patient who reports abdominal and back pain has been diagnosed with
bacteria in the urine. What is the appropriate term for involvement of the upper
urinary tract that is likely to cause such symptoms?
A. Cystitis
B. Pyelonephritis
C. Urinary tract infection
D. Asymptomatic bacteriuria
Answer: B
Rationale: Pyelonephritis is an infection of the upper urinary tract, specifically the
renal pelvis and kidney. It typically presents with flank or back pain, fever, and
systemic symptoms. Cystitis is a lower urinary tract infection (bladder) with
symptoms like dysuria and frequency. Asymptomatic bacteriuria is bacteria in the
urine without symptoms. A UTI is a general term.
11. With which bacteria is acute glomerulonephritis associated?
