Question

Which laboratory finding indicates the resolution of a patient's acute pancreatitis?

Answer 1

Correct Answers:

Decreasing serum amylase level

Rationale :

✅ Acute pancreatitis is primarily diagnosed and monitored through elevated serum amylase and lipase levels, as these enzymes are released into the bloodstream when the pancreas is inflamed.

✅ As the inflammation resolves, serum amylase levels begin to decline, indicating improved pancreatic function and reduced pancreatic cell injury.

✅ Monitoring enzyme levels is essential in tracking the patient’s response to treatment.

✅ An increasing hemoglobin level or bilirubin level may reflect other unrelated conditions and does not directly indicate pancreatitis resolution.

Answer 2

Correct Answers:

Perforation

Rationale :

🍃Perforation is a life-threatening complication of peptic ulcer disease and occurs when the ulcer erodes through the entire wall of the stomach or duodenum, creating an opening.

🍃This allows gastric or duodenal contents to spill into the peritoneal cavity, leading to chemical peritonitis and potentially bacterial peritonitis.

🍃The client may present with sudden severe abdominal pain, a rigid abdomen, and signs of shock.

🍃This is a surgical emergency and not seen with dumping syndrome, gastric outlet obstruction, or hemorrhage.

Answer 3

Correct Answers:

Ammonia

Rationale :

▲In cirrhosis, liver dysfunction impairs the conversion of ammonia to urea, leading to elevated serum ammonia levels.

▲This can result in hepatic encephalopathy, characterized by confusion, altered mental status, and even coma.

▲ Lactulose promotes the excretion of ammonia through the stool by acidifying the colon, which traps ammonia and prevents its absorption.

▲Though also used as a laxative, in this context, its primary therapeutic purpose is to manage hyperammonemia in liver disease.

Answer 4

Correct Answers:

Potassium

Rationale :

✔️ Hemodialysis is used to correct fluid and electrolyte imbalances in clients with kidney failure.

✔️ One of the primary goals is to reduce elevated potassium levels (hyperkalemia), which can lead to life-threatening cardiac arrhythmias.

✔️ During dialysis, potassium is filtered out of the blood through diffusion across the dialysis membrane. This effectively lowers serum potassium levels post-treatment.

✔️Calcium and protein may remain relatively stable, while RBC count can actually decrease due to hemolysis or blood loss during dialysis.

Answer 5

Correct Answers:

Hyperkalemia

Rationale :

✍️Prerenal AKI results from impaired renal perfusion, which reduces the kidney's ability to filter waste and maintain electrolyte balance.

✍️As glomerular filtration decreases, potassium accumulates in the blood due to reduced excretion, leading to hyperkalemia.

✍️This is a critical finding as it increases the risk of cardiac arrhythmias.

✍️Hypernatremia and hypercalcemia are not typical of prerenal AKI, and phosphorus retention is more likely than hypophosphatemia.

Answer 6

Correct Answers:

The client reports that they have had two urinary tract infections (UTIs) in the past 10 months.

Rationale :

Pyelonephritis is a serious upper urinary tract infection that often develops from ascending lower UTIs, especially in individuals with a history of recurrent infections.
A client reporting multiple UTIs in the recent past is at increased risk of the infection spreading to the kidneys.
This history supports the diagnosis and guides treatment strategies.
Other options, such as high calcium intake or familial genetic conditions, are not commonly linked to pyelonephritis.

Answer 7

Correct Answers:

There is injury to the renal tubular cells.

Rationale :

♥️Acute tubular necrosis (ATN) is the most common cause of intrarenal AKI, characterized by damage to the renal tubular epithelial cells, often due to ischemia or nephrotoxins.

♥️ Damaged tubular cells slough off, clogging the nephron and impairing glomerular filtration.

♥️This leads to decreased GFR, fluid retention, and accumulation of waste products.

♥️ The process also triggers an inflammatory response, further compromising kidney function.

Answer 8

Correct Answers:

Tell the patient to clean the urethral area, void a small amount into the toilet, then void directly into a sterile container.

Rationale :

🔷 A clean-catch midstream specimen is the gold standard for urine culture as it minimizes contamination from skin flora.

🔷The client should be instructed to clean the perineal area, begin urinating into the toilet to flush out contaminants, then collect the midstream portion in a sterile container.

🔷 This ensures that the sample accurately reflects the urinary tract flora.

🔷 Invasive methods like catheterization are not necessary unless the patient cannot void.

Answer 9

Correct Answers:

Liver cirrhosis

Rationale :

♦️Esophageal varices and portal hypertension are serious complications typically resulting from liver cirrhosis, where scarring of liver tissue obstructs normal blood flow through the liver.

♦️This leads to increased pressure in the portal vein, which in turn causes collateral blood vessels to develop, such as esophageal varices. These dilated veins are fragile and prone to rupture.

♦️ Recognizing cirrhosis as the root cause is essential for effective treatment planning and prevention of bleeding.

Answer 10

Correct Answers:

Cardiac rhythm

Rationale :

✔️ In clients with hyperkalemia, the most life-threatening complication is cardiac dysrhythmias.

✔️ Calcium gluconate is administered not to reduce potassium levels directly but to stabilize the myocardium and reduce the excitability of cardiac cells.

✔️ Therefore, the priority assessment after administration is the cardiac rhythm, monitored via ECG.

✔️This helps determine if the treatment is effectively preventing arrhythmias while additional therapies work to lower serum potassium levels.
