A nurse is providing care to a cancer client. Which protein in plasma functions primarily as immunologic agents?
- A. Gamma globulins
- B. Albumin
- C. Fibrinogen
- D. Beta globulins

A client is taking a medication that has the side effect of depressing the hematopoietic system. What signs of leukopenia should the nurse monitor for while the client is taking this drug?
- A. Fever, sore throat, and chills
- B. Nausea and vomiting
- C. Diarrhea, diaphoresis, and fever
- D. Intolerance to heat and rash
Correct Answer: A
Rationale: Closely monitor clients taking medications that depress the hematopoietic system, particularly thrombocytes and leukocytes. Signs of leukopenia include fever, sore throat, and chills. Nausea and vomiting, diarrhea, diaphoresis, heat intolerance, and rash are not indicative of leukocytosis.
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

The nurse observes that a client who had an arterial blood gas performed 30 minutes ago is still oozing blood from the puncture site. Pressure was held to the site for 5 minutes after the puncture and another 5 minutes when the site was still oozing. What factor does the nurse know will participate in the ability for the blood to clot?
- A. Platelets
- B. Leukocytes
- C. Erythrocytes
- D. Albumin
Correct Answer: A
Rationale: Platelets participate in clotting blood. Leukocytes protect against infection. Erythrocytes transport oxygen, and albumin affects intravascular osmotic pressure.
