The nurse is assisting with the preparation of a blood transfusion for a patient. Which type of fluid should the nurse select to transfuse with the blood?
- A. 0.9% normal saline
- B. Dextrose 5% and water
- C. Dextrose 5% and 0.9% normal saline
- D. Dextrose 5% and 0.45% normal saline
Correct Answer: A
Rationale: Rationale: A 0.9% normal saline solution is the correct choice for blood transfusion because it is isotonic, which closely matches the osmolarity of blood. This helps prevent hemolysis and maintains the integrity of red blood cells during transfusion. Other choices such as B (dextrose 5% and water), C (dextrose 5% and 0.9% normal saline), and D (dextrose 5% and 0.45% normal saline) are incorrect because they do not provide the necessary isotonic environment for safe blood transfusion, risking hemolysis or other complications.

A nurse is teaching a client about taking ferrous sulfate to treat iron deficiency anemia. Which of the following instructions should the nurse include? (Select All)
- A. Eat iron-enriched foods.
- B. Spread the dosage across each day.
- C. Take the drug on an empty stomach.
- D. Report dark green or black stools.
Correct Answer: A
Rationale: The correct answer is A: Eat iron-enriched foods. Iron-enriched foods help increase iron levels in the body, aiding in treating iron deficiency anemia. Consuming these foods along with ferrous sulfate can enhance the effectiveness of the treatment.
B: Spreading the dosage across each day is important to maintain consistent iron levels but is not the most crucial aspect of treatment.
C: Taking the drug on an empty stomach may enhance absorption but can also lead to stomach upset, so it is not necessary for all clients.
D: Reporting dark green or black stools is important to monitor for gastrointestinal bleeding, but it is not an instruction related to taking ferrous sulfate.
What is the nurse's priority when caring for a client who just completed a bone marrow aspiration and biopsy?
- A. Teach the client to avoid activity for 24 to 48 hours to prevent infection.
- B. Administer a nonsteroidal anti-inflammatory drug (NSAID) to promote comfort.
- C. Check the pressure dressing frequently for signs of excessive or active bleeding.
- D. Report the laboratory results to the primary health care provider.
Correct Answer: C
Rationale: The correct answer is C: Check the pressure dressing frequently for signs of excessive or active bleeding. This is the priority because post bone marrow aspiration and biopsy, there is a risk of bleeding due to the procedure. By checking the dressing, the nurse can assess for any signs of excessive bleeding or hematoma formation, which are crucial to prevent complications.
A: Teaching the client to avoid activity is important but not the priority immediately post-procedure.
B: Administering NSAIDs may not be appropriate as they can increase the risk of bleeding.
D: Reporting the lab results is important but not the priority over ensuring immediate post-procedure safety.
A 60-year-old patient with chronic myeloid leukemia will be treated in the home setting and the nurse is preparing appropriate health education. What topic should the nurse emphasize?
- A. The importance of adhering to the prescribed drug regimen
- B. The need to ensure that vaccinations are up to date
- C. The importance of daily physical activity
- D. The need to avoid shellfish and raw foods
Correct Answer: A
Rationale: The correct answer is A: The importance of adhering to the prescribed drug regimen. This is crucial in managing chronic myeloid leukemia effectively. Medication adherence is essential to control the disease and prevent complications. Skipping doses can lead to treatment failure or drug resistance.
B: While vaccinations are important, they are not the top priority in managing chronic myeloid leukemia.
C: Daily physical activity is beneficial for overall health but is not the primary concern in this case.
D: Avoiding shellfish and raw foods is not a key aspect of managing chronic myeloid leukemia.
During haemostasis, prostacyclin
- A. Cleaves prothrombin into thrombin
- B. Causes vasodilation
- C. Stimulates platelet aggregation
- D. Activates fibrinolysis
Correct Answer: B
Rationale: Prostacyclin is a vasodilator, which means it causes blood vessels to widen, leading to decreased blood pressure and increased blood flow. During haemostasis, this vasodilation helps in maintaining blood flow and preventing platelet aggregation in the damaged area. Option A is incorrect because prostacyclin does not cleave prothrombin into thrombin. Option C is incorrect as prostacyclin inhibits platelet aggregation. Option D is incorrect because prostacyclin does not directly activate fibrinolysis. In summary, the correct answer is B because prostacyclin's vasodilation function plays a crucial role in haemostasis by preventing excessive clot formation and maintaining blood flow.
Which of the following is false regarding Burkitt's lymphoma?
- A. Associated with translocation of c-myc gene on chromosome 18
- B. Usually presents with abdominal involvement in HIV patients
- C. Common in Africa children due to Epstein Barr infection after malaria exposure.
- D. Histologically characterized by a 'starry sky' appearance
Correct Answer: A
Rationale: The correct answer is A because Burkitt's lymphoma is associated with the translocation of the c-myc gene on chromosome 8, not chromosome 18. This translocation results in the overexpression of c-myc, leading to uncontrolled cell proliferation. Choice B is incorrect as Burkitt's lymphoma commonly presents with jaw or facial bone involvement in HIV patients. Choice C is incorrect as Burkitt's lymphoma is commonly seen in African children due to Epstein-Barr virus infection, not necessarily after malaria exposure. Choice D is incorrect as Burkitt's lymphoma is histologically characterized by a "starry sky" appearance due to the presence of numerous macrophages engulfing debris from apoptotic cells.
