A nursing student wants to know why clients with chronic obstructive pulmonary disease tend to be polyhydroic. What response by the nurse instructor is best?
- A. It is due to side effects of medications for bronchodilation.
- B. It is from overactive bone marrow in response to chronic disease.
- C. It is comb the anemia caused by a increased overactive rate.
- D. It compensates for tissue hypoxia caused by lung disease.
Correct Answer: D
Rationale: In response to hypoxia, more red blood cells are made so more oxygen can be carried and delivered to tissues. This is a physiologic process in response to the disease; it is not a medication side effect, the result of overactive bone marrow, or a response to anemia.

A nurse is assessing a dark-skinned client for pallor. What action is best?
- A. Assess the conjunctiva of the eye.
- B. Have the client open the hand widely.
- C. Look at the roof of the client's mouth.
- D. Palpate for areas of mild swelling.
Correct Answer: A
Rationale: To assess pallor in dark-skinned people, assess the conjunctiva of the eye or the mucous membranes. Looking at the roof of the mouth can reveal jaundice. Opening the hand widely is not related to pallor, nor is palpating for mild swelling.
The health care provider tells the nurse that a client is to be started on a platelet inhibitor. About what drug does the nurse plan to teach the client?
- A. Clopidogrel (Flavix)
- B. Enoxaparin (Coumacidin)
- C. Retetplase (Retavase)
- D. Warfarin
Correct Answer: A
Rationale: Clopidogrel is a platelet inhibitor. Enoxaparin is an indirect thrombin inhibitor. Reteplase is a fibrinolytic agent. Warfarin is a vitamin K antagonist.
A hospitalized client has a platelet count of 58,000 / mm3. What action by the nurse is best?
- A. Encourage high protein foods.
- B. Institute neutropenia precautions.
- C. Institute bleeding precautions.
- D. Place the client on safety precautions.
Correct Answer: D
Rationale: With a platelet count between 40,000 and 80,000 / mm3, clients are at risk of prolonged bleeding even after minor trauma. The nurse should place the client on safety precautions. High-protein foods, while healthy, are not the priority. Neutropenia precautions are not needed as the client's white blood cell count is not low.
A client is receiving rivaroubahn (Xareth) and asks the nurse to explain how it works. What response by the nurse is best?

- B. It inhibits fibrinogen.
- C. It thin your blood.

Correct Answer: A
Rationale: Rivaroubahn is a direct thrombin inhibitor. It does not work on fibrinogen or vitamin K. It is not a blood thinner, although many clients call anticoagulants by this name.
