A patient with severe anemia is prescribed erythropoietin. What is the primary action of this medication?
- A. Stimulate white blood cell production
- B. Increase platelet count
- C. Promote red blood cell production
- D. Enhance clotting factor production
Correct Answer: C
Rationale: The correct answer is C: Promote red blood cell production. Erythropoietin is a hormone that stimulates the bone marrow to produce more red blood cells, helping to treat anemia. It does not stimulate white blood cell production (A), increase platelet count (B), or enhance clotting factor production (D). White blood cells are involved in the immune response, platelets are responsible for clotting, and clotting factors are proteins involved in the blood clotting process. Therefore, the primary action of erythropoietin is to specifically target red blood cell production to address anemia.

A patient who is diagnosed with cervical cancer that is classified as Tis, N0, M0 asks the nurse what the letters and numbers mean. Which response by the nurse is most appropriate?
- A. The cancer involves only the cervix.
- B. The cancer cells closely resemble normal cells.
- C. Further testing is necessary to determine the spread of the cancer.
- D. Determining the original site of the cervical cancer is challenging.
Correct Answer: A
Rationale: Step-by-step rationale for why answer A is correct:
1. Tis refers to carcinoma in situ, meaning the cancer is limited to the surface layer of cells in the cervix.
2. N0 indicates no regional lymph node involvement.
3. M0 indicates no distant metastasis.
4. Therefore, the cancer is localized only to the cervix, making answer A correct.
Summary:
B: Incorrect - Does not address the staging information provided in Tis, N0, M0.
C: Incorrect - The staging information is already provided, and further testing may not be necessary at this stage.
D: Incorrect - Staging information does not indicate difficulty in determining the original site of the cancer.
When providing dietary instructions to a client with cirrhosis, which dietary restriction is important for the nurse to emphasize?
- A. Low-protein diet
- B. Low-sodium diet
- C. High-fiber diet
- D. High-calcium diet
Correct Answer: B
Rationale: Rationale: Correct answer is B (Low-sodium diet) for cirrhosis because sodium can worsen fluid retention and increase ascites. A (Low-protein diet) is not necessary unless hepatic encephalopathy is present. C (High-fiber diet) can help with constipation but not a primary concern. D (High-calcium diet) is not a priority for cirrhosis management.
Why is a low-protein diet recommended for a patient with renal failure?
- A. To prevent fluid overload
- B. To reduce nitrogenous waste
- C. To maintain electrolyte balance
- D. To prevent hyperglycemia
Correct Answer: B
Rationale: The correct answer is B: To reduce nitrogenous waste. In renal failure, the kidneys cannot effectively filter waste products like urea and creatinine, leading to their accumulation in the blood. A low-protein diet reduces the production of these nitrogenous wastes, lessening the burden on the kidneys.
A low-protein diet does not directly prevent fluid overload (A), maintain electrolyte balance (C), or prevent hyperglycemia (D) in renal failure. These functions are typically managed through other dietary modifications and treatments specific to each condition.
A patient with cirrhosis of the liver and ascites is scheduled for a paracentesis. What should the nurse do to prepare the patient for the procedure?
- A. Have the patient void immediately before the procedure.
- B. Position the patient flat in bed.
- C. Administer a full liquid diet.
- D. Encourage the patient to ambulate for 30 minutes.
Correct Answer: A
Rationale: The correct answer is A: Have the patient void immediately before the procedure. This step is crucial to prevent accidental puncture of the bladder during paracentesis. Voiding helps empty the bladder, reducing the risk of injury and ensuring a safer procedure.
Incorrect choices:
B: Position the patient flat in bed - Incorrect, as the patient should be in a sitting position with legs dangling over the side of the bed during the procedure.
C: Administer a full liquid diet - Incorrect, as a full liquid diet is not necessary for paracentesis preparation.
D: Encourage the patient to ambulate for 30 minutes - Incorrect, as ambulation is not relevant to preparing for paracentesis.
What is the primary cause of jaundice in a client with liver cirrhosis?
- A. Decreased bile production
- B. Increased bilirubin levels
- C. Hepatic inflammation
- D. Portal hypertension
Correct Answer: B
Rationale: The primary cause of jaundice in a client with liver cirrhosis is increased bilirubin levels. Liver cirrhosis impairs the liver's ability to process bilirubin, leading to its accumulation in the bloodstream. This excess bilirubin then causes the yellow discoloration of the skin and eyes characteristic of jaundice.
Incorrect Choices:
A: Decreased bile production is not the primary cause of jaundice in liver cirrhosis. While decreased bile flow may contribute to jaundice, it is secondary to the impaired bilirubin processing.
C: Hepatic inflammation is a common feature of liver cirrhosis but is not the direct cause of jaundice in this context.
D: Portal hypertension is a complication of liver cirrhosis but is not the primary cause of jaundice.
