A client with acute pancreatitis is experiencing severe abdominal pain. Which enzyme level should the nurse monitor closely?
- A. Serum amylase.
- B. Serum sodium.
- C. Serum calcium.
- D. Serum potassium.
Correct Answer: A
Rationale: The correct answer is A: Serum amylase. In acute pancreatitis, damaged pancreatic cells release amylase into the bloodstream, causing elevated serum amylase levels. Monitoring serum amylase helps in diagnosing and assessing the severity of pancreatitis.
Incorrect choices:
B: Serum sodium - Serum sodium levels are typically not directly affected by pancreatitis.
C: Serum calcium - While hypocalcemia can occur in severe pancreatitis, monitoring serum calcium is not as specific for pancreatitis diagnosis or severity assessment as serum amylase.
D: Serum potassium - Potassium levels may be affected in pancreatitis due to vomiting or dehydration, but monitoring serum potassium is not as specific to pancreatitis as serum amylase.

The nurse is administering sevelamer (RenaGel) during lunch to a client with end-stage renal disease (ESRD). The client asks the nurse to bring the medication later. The nurse should describe which action of RenaGel as an explanation for taking it with meals?
- A. Prevents indigestion associated with the ingestion of spicy foods.
- B. Binds with phosphorus in foods and prevents absorption.
- C. Promotes stomach emptying and prevents gastric reflux.
- D. Buffers hydrochloric acid and prevents gastric erosion.
Correct Answer: B
Rationale: The correct answer is B: Binds with phosphorus in foods and prevents absorption. Sevelamer (RenaGel) is a phosphate binder used in ESRD to reduce phosphorus levels. Taking it with meals allows it to bind with phosphorus in food, preventing its absorption in the gastrointestinal tract. This helps in controlling hyperphosphatemia, a common complication in ESRD. Choices A, C, and D are incorrect as RenaGel does not prevent indigestion, promote stomach emptying, or buffer hydrochloric acid.
A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?
- A. To lower blood sugar levels
- B. To reduce ammonia levels
- C. To treat liver inflammation
- D. To improve bile flow
Correct Answer: B
Rationale: Rationale: Lactulose is prescribed for liver cirrhosis to reduce ammonia levels. It works by promoting the excretion of ammonia in the stool, preventing its accumulation in the bloodstream. This helps prevent hepatic encephalopathy, a serious complication of cirrhosis. Other choices are incorrect because lactulose does not directly affect blood sugar levels, liver inflammation, or bile flow in the context of liver cirrhosis.
The community health nurse is working in a multi-ethnic health center. In what situation should the nurse intervene?
- A. An Asian-American mother reports using cupping to treat infection, resulting in a pattern of red round marks on her toddler's back.
- B. A Hispanic pregnant client who is often late for appointments, arrives late for today's appointment.
- C. A Native-American who is being interviewed will not make direct eye contact when asked about violence in the home.
- D. An African-American infant who is spitting up milk has lost 6 ounces since last week's clinic visit.
Correct Answer: D
Rationale: The correct answer is D because an African-American infant losing weight rapidly is a sign of potential malnutrition or health issue that requires immediate intervention. The nurse should assess the infant's feeding, growth, and health status to address the problem promptly.
Choice A is incorrect as cupping is a cultural practice that may not necessarily harm the child and should be respected. Choice B is incorrect as being late for appointments is not a direct health risk that requires immediate intervention. Choice C is incorrect as avoiding direct eye contact is a cultural norm for some Native-American individuals and does not indicate a health emergency.
A patient with anemia is prescribed ferrous sulfate. What advice should the nurse give regarding the administration of this medication?
- A. Take with dairy products to increase absorption.
- B. Take on an empty stomach for best absorption.
- C. Avoid vitamin C while taking this medication.
- D. Take before bedtime.
Correct Answer: B
Rationale: The correct answer is B: Take on an empty stomach for best absorption. Ferrous sulfate is best absorbed on an empty stomach to maximize its effectiveness. When taken with food or dairy products (Choice A), the absorption of iron is reduced. Vitamin C actually enhances the absorption of iron, so avoiding it (Choice C) is not recommended. Taking the medication before bedtime (Choice D) may lead to gastrointestinal side effects and is not optimal for absorption.
When caring for a client with hepatic encephalopathy, why is a low-protein diet recommended by the nurse?
- A. Hyperglycemia
- B. Hypoglycemia
- C. Increased ammonia levels
- D. Electrolyte imbalance
Correct Answer: C
Rationale: The correct answer is C: Increased ammonia levels. In hepatic encephalopathy, the liver is unable to metabolize ammonia into urea, leading to increased ammonia levels in the blood. A low-protein diet helps reduce ammonia production in the gut, thereby decreasing ammonia levels in the blood and improving symptoms. Hyperglycemia (A) and hypoglycemia (B) are not directly related to the rationale for a low-protein diet in hepatic encephalopathy. Electrolyte imbalance (D) is not specifically addressed by a low-protein diet in this context.
