A client has type AB blood. What type of blood must this client receive during a blood transfusion?
- A. They can receive blood from persons with any type of blood if the RH factor is compatible.
- B. They can only receive blood from persons with type A blood.
- C. They can only receive blood from persons with type B blood.
- D. They can only receive blood from persons with type O blood if the RH factor is positive.
Correct Answer: A
Rationale: People with type AB blood are considered universal recipients because both A and B antigens are present on the red cell membrane. Clients with type AB blood can receive blood from persons with any type of blood, but the Rh factor must be compatible. The other distractors are incorrect because the client can receive blood from any type.

- A. Vitamin Bâ??â??
- B. Vitamin C
- C. Vitamin B6
- D. Vitamin E

Why would it be important for the nurse to obtain information regarding the dietary history of a client with a possible abnormality of the hematopoietic or lymphatic system?
- A. It could determine if the illness is self-induced by nutritional starvation.
- B. If the client has impaired protein intake, it will cause diseases of the hematopoietic system.
- C. Altered nutrition is the cause of abnormalities of the hematopoietic and lymphatic system.
- D. Compromised nutrition interferes with production of blood cells and hemoglobin.
Correct Answer: D
Rationale: The nurse obtains a dietary history because compromised nutrition interferes with the production of blood cells and hemoglobin. The history cannot determine if the illness is self-induced by starvation. Nutritional deficiencies do not cause diseases of the hematopoietic system and lymphatic system.
Albumin is a protein in the plasma portion of the blood. Under normal conditions, albumin cannot pass through the wall of a capillary. What significance is this for the vascular compartment?
- A. Helps push oxygen into the tissues of the body
- B. Retains leukocytes in the vascular compartment
- C. Helps retain fluid in the vascular compartment
- D. Absorbs carbon dioxide from the tissues for transport to the lungs
Correct Answer: C
Rationale: Under normal conditions, albumin cannot pass through a capillary wall. Consequently, albumin helps maintain the osmotic pressure that retains fluid in the vascular compartment. Albumin does not push oxygen into the tissues of the body or absorb carbon dioxide for transport to the lungs. Albumin also does not retain leukocytes in the vascular compartment.
The nurse will be assisting the physician with a bone marrow aspiration. Where should the nurse cleanse, clip hair, and drape the skin prior to the procedure?
- A. Over the posterior superior iliac crest.
- B. Over the anterior tibia
- C. Over the radius
- D. Over the metatarsal area
Correct Answer: A
Rationale: The posterior superior iliac crest is the preferred site because no vital organs or blood vessels are nearby. The anterior tibia, radius, or metatarsal area are not used for bone marrow aspirations.
