1. What type of drug is lamivudine, used for the management of HIV infection?
- A. CCR5 antagonist
- B. fusion inhibitor
- C. nucleoside reverse transcriptase inhibitor
- D. protease inhibitor
Correct answer: C
Rationale: Lamivudine belongs to the class of nucleoside reverse transcriptase inhibitors (NRTIs), making choice C the correct answer. NRTIs like lamivudine work by inhibiting the reverse transcriptase enzyme, an essential component for the HIV virus to replicate. Choices A, B, and D are incorrect because lamivudine does not function as a CCR5 antagonist, fusion inhibitor, or protease inhibitor in the management of HIV infection.
2. The nurse knows that after receiving the blood from the blood bank, it should be administered within:
- A. 1 hour
- B. 2 hours
- C. 4 hours
- D. 6 hours
Correct answer: D
Rationale: Blood transfusions need to be administered promptly after receiving the blood from the blood bank to ensure patient safety and effectiveness. Waiting too long can lead to complications such as bacterial growth in the blood product, which can be harmful when infused. Administering the blood within 6 hours is crucial to prevent such risks. Choices A, B, and C are incorrect because waiting for 1, 2, or 4 hours respectively can increase the likelihood of complications associated with delayed transfusion.
3. Select all that apply. Which nutrients are needed by the body to make hemoglobin?
- A. Iron
- B. Vitamin B12
- C. Niacin
- D. Folate
Correct answer: A
Rationale: The correct answer is A: Iron. Iron is an essential nutrient needed by the body to make hemoglobin, the protein in red blood cells that carries oxygen. While other nutrients like vitamin B12, niacin, and folate are important for various bodily functions, they are not directly involved in the production of hemoglobin. Vitamin B12 is essential for nerve function and DNA synthesis, niacin is important for metabolism, and folate is crucial for cell division and DNA synthesis. Therefore, only iron is specifically required for hemoglobin production.
4. A nurse is caring for a client with a major burn injury and is receiving TPN. Which of the following lab tests is the priority for the nurse to use to confirm the client is receiving adequate nutrition?
- A. Iron
- B. Magnesium
- C. Folic acid
- D. Prealbumin
Correct answer: D
Rationale: Prealbumin is a sensitive indicator of protein status and nutrition, making it a priority for assessing nutritional adequacy in clients receiving TPN. Iron, magnesium, and folic acid levels are important for overall health but do not specifically indicate nutritional adequacy in the context of TPN administration.
5. Which foods increase iron absorption when consumed with nonheme iron? (SATA)
- A. Kiwi
- B. Strawberries
- C. Coffee
- D. A, B
Correct answer: D
Rationale: Kiwi and strawberries are high in vitamin C, which increases iron absorption.
