1. Which of the following lab values would indicate symptomatic AIDS in the medical chart? (T4 cell count per deciliter)
- A. Greater than 1000 cells per deciliter
- B. Less than 500 cells per deciliter
- C. Greater than 2000 cells per deciliter
- D. Less than 200 cells per deciliter
Correct answer: D
Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.
2. A child with newly diagnosed leukemia is receiving chemotherapy. Which would be included in his plan of care by the nurse?
- A. Place the child in a negative pressure isolation room
- B. Administer prophylactic IV antibiotics
- C. Avoid high protein food intake
- D. Teach family and visitors handwashing techniques
Correct answer: D
Rationale: The correct answer is to teach family and visitors handwashing techniques. Any client on chemotherapy should have good infection control measures in place, such as handwashing by all who they encounter. Placing the child in a negative pressure isolation room (Choice A) is not necessary unless specifically indicated for a certain condition. Administering prophylactic IV antibiotics (Choice B) may not be part of the standard care plan for a child with leukemia receiving chemotherapy. Avoiding high protein food intake (Choice C) is not directly related to infection control and may not be necessary unless there are specific dietary restrictions.
3. How can a diet high in fiber content benefit an individual?
- A. aid in rapid weight loss.
- B. reduce diabetic ketoacidosis.
- C. lower cholesterol.
- D. reduce the requirement for folate.
Correct answer: C
Rationale: A diet high in fiber content can help lower cholesterol levels. Fiber-rich foods such as grains, apples, potatoes, and beans are known to aid in reducing cholesterol by binding to cholesterol in the digestive system and preventing its absorption into the bloodstream. Choice A is incorrect as the question does not specify losing weight rapidly but rather focuses on the benefits of a high-fiber diet, which includes aiding in weight management through promoting satiety and regulating digestion. Choice B is incorrect because while fiber helps manage blood sugar levels, it is not directly related to reducing diabetic ketoacidosis, a serious complication of diabetes. Choice D is incorrect as a high-fiber diet does not reduce the need for folate; however, it can aid in the absorption of folate and other essential nutrients.
4. Which of the following diseases or conditions is least likely to be associated with an increased potential for bleeding?
- A. metastatic liver cancer
- B. gram-negative septicemia
- C. pernicious anemia
- D. iron-deficiency anemia
Correct answer: C
Rationale: Pernicious anemia is least likely to be associated with an increased potential for bleeding compared to the other conditions listed. Pernicious anemia is a condition resulting from vitamin B12 deficiency due to the absence of intrinsic factor, necessary for B12 absorption. While pernicious anemia can lead to neurological issues, it is not directly linked to an increased risk of bleeding. Metastatic liver cancer can cause liver dysfunction leading to coagulopathy, gram-negative septicemia can result in disseminated intravascular coagulation (DIC), and iron-deficiency anemia can lead to microcytic hypochromic red blood cells, increasing the risk of bleeding. Therefore, pernicious anemia is the least likely to be associated with an increased potential for bleeding out of the options provided.
5. What happens if folic acid is administered to treat anemia without determining its underlying cause?
- A. Erythropoiesis is inhibited
- B. Excessive levels of folic acid might accumulate, causing toxicity
- C. The symptoms of pernicious anemia might be masked, delaying treatment
- D. Intrinsic factor is destroyed
Correct answer: C
Rationale: When folic acid is given without determining the underlying cause of anemia, the symptoms of pernicious anemia may be masked, potentially delaying the correct treatment. Folic acid alone does not protect against the central nervous system changes seen in pernicious anemia, which are related to Vitamin B12 deficiency. Folic acid and Vitamin B12 are both crucial for cell growth and division. Administering folic acid without knowing the specific type of anemia could lead to a delay in addressing the root cause. Option A is incorrect because folic acid is essential for erythropoiesis, the production of red blood cells. Option B is incorrect as excessive folic acid can cause toxicity, but it is not the primary concern in this context. Option D is incorrect because folic acid treatment for anemia does not directly impact intrinsic factor, which is related to Vitamin B12 absorption.
