The chemotherapeutic agent 5-fluorouracil (5-FU) is ordered for a client as an adjunct measure to surgery. Which statement about chemotherapy is true?
- A. It is a local treatment affecting only tumor cells.
- B. It is a systemic treatment affecting both tumor and normal cells.
- C. It has not yet been proven an effective treatment for cancer.
- D. It is often the drug of choice because it causes few, if any, side effects.
Correct Answer: B
Rationale: The correct answer is that chemotherapy is a systemic treatment affecting both tumor and normal cells. 5-FU, as an antimetabolic drug, inhibits DNA synthesis and interferes with cell replication systemically. It affects all rapidly growing cells, including malignant and normal ones. This drug is used as adjuvant therapy for various cancers. Choice A is incorrect because chemotherapy affects both tumor and normal cells, not just tumor cells. Choice C is incorrect as chemotherapy has been proven effective in treating cancer. Choice D is incorrect because chemotherapy often causes side effects like bone marrow depression, anorexia, stomatitis, nausea, and vomiting.

The LPN is preparing to ambulate a client post total knee replacement. Which of the following actions should the nurse perform prior to ambulating the client?
- A. Assist the client to a sitting position at the edge of the bed
- B. Have the client march in place for 30 seconds
- C. Have the client raise his arms above his head
- D. Ask the client the last time he fell
Correct Answer: A
Rationale: The correct action to perform before ambulating a client post total knee replacement is to assist the client to a sitting position at the edge of the bed. This step is crucial to prevent orthostatic hypotension and ensure the client is ready to stand and walk safely. Having the client march in place or raise his arms above his head are not necessary preparations for ambulation. While knowing about the client's fall history is important for safety reasons, it is not the priority action immediately before ambulating the client.
When treating anemia in clients with renal failure, erythropoietin should be given in conjunction with:
- A. iron, folic acid, and B12.
- B. an increase in protein in the diet.
- C. vitamins A and C.
- D. an increase in calcium in the diet.
Correct Answer: A
Rationale: Erythropoietin is used to stimulate red blood cell production in clients with renal failure. To effectively increase red blood cell production, adequate levels of iron, folic acid, and B12 are necessary. These nutrients play crucial roles in erythropoiesis. Choices B, an increase in protein in the diet, is not directly related to enhanced erythropoiesis and can potentially worsen uremia. Choices C and D, vitamins A and C, and an increase in calcium in the diet, are not directly involved in red blood cell production and are not essential in this context.
When discussing possible complications of pregnancy with a client, the nurse should explain that all of the following are symptoms of urinary tract infection (UTI). Which of the following is least indicative of UTI during pregnancy?
- A. low back pain
- B. urinary frequency
- C. GI distress
- D. malaise
Correct Answer: B
Rationale: Urinary frequency is least indicative of UTI during pregnancy. It is a common minor discomfort of pregnancy caused by pressure of the growing uterus on the bladder. As the uterus rises in the second trimester, there are usually no problems. Frequency may return in the third trimester when the uterus drops into the pelvic cavity. UTI symptoms include low back pain, suprapubic discomfort, and malaise, and are confirmed by laboratory findings. Low back pain, GI distress, and malaise are more closely associated with UTI during pregnancy compared to urinary frequency.
What is pica?
- A. dependency on alcohol
- B. increased iron in the diet
- C. the sickle cell trait
- D. eating ice
Correct Answer: D
Rationale: Pica is a disorder characterized by the ingestion of nonfood substances, which can lead to a clinical iron deficiency. It may be the first sign of an underlying issue. Individuals with pica consume a variety of nonfood items such as ice, clay, dirt, or paste. Choice A, dependency on alcohol, is incorrect as it is not related to pica. Choice B, increased iron in the diet, is incorrect because pica involves ingesting nonfood items rather than having an increased intake of iron. Choice C, the sickle cell trait, is unrelated to pica and is therefore incorrect.
The healthcare provider should utilize data about which of the following to provide information about the nutritional status of a client being evaluated for malnutrition?
- A. triceps skinfold measurement
- B. fasting blood glucose level
- C. hemoglobin A1c level
- D. serum lipid profile results
Correct Answer: A
Rationale: Objective anthropometric measurements such as triceps skinfold and mid-arm circumference (MAC), along with weight, are usually used to diagnose malnutrition. Triceps skinfold measurement specifically helps assess body fat and muscle mass, providing valuable information about the client's nutritional status. Fasting blood glucose level, hemoglobin A1c level, and serum lipid profile results are important tests in assessing different aspects of health such as diabetes management and cardiovascular risk, but they are not specific indicators of malnutrition.
