A nurse is caring for a client who has chronic renal disease and is receiving therapy with epoetin alfa.
Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?
The hematocrit (Hct).
The erythrocyte sedimentation rate (ESR).
The platelet count.
The leukocyte count.
The Correct Answer is A
Choice A rationale
The hematocrit (Hct). This statement is correct. Epoetin alfa is used to treat anemia by stimulating the production of red blood cells. An increase in hematocrit levels indicates a therapeutic effect of the medication, as it reflects an increase in the proportion of red blood cells in the blood.
Choice B rationale
The erythrocyte sedimentation rate (ESR). This statement is incorrect. The ESR is a non- specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa. It does not provide information about red blood cell production or anemia.
Choice C rationale
The platelet count. This statement is incorrect. The platelet count measures the number of platelets in the blood, which are involved in clotting. It is not affected by epoetin alfa therapy and does not indicate the therapeutic effect of the medication.
Choice D rationale
The leukocyte count. This statement is incorrect. The leukocyte count measures the number of white blood cells in the blood, which are involved in the immune response. It is not affected by epoetin alfa therapy and does not indicate the therapeutic effect of the medication.

Correct Answer is A
Explanation
Choice A rationale
Disseminated intravascular coagulation (DIC) is caused by abnormal coagulation involving fibrinogen. In DIC, there is widespread activation of the coagulation cascade, leading to the formation of small blood clots throughout the bloodstream. This process consumes clotting factors and platelets, increasing the risk of severe bleeding.
Choice B rationale
DIC is not a genetic disorder involving a vitamin K deficiency. It is typically a secondary condition resulting from other underlying issues such as sepsis, trauma, or malignancy. Vitamin K deficiency can lead to bleeding disorders, but it is not the cause of DIC13.
Choice C rationale
DIC is characterized by a decreased platelet count, not an elevated one. The consumption of platelets and clotting factors in the formation of microthrombi leads to thrombocytopenia and an increased risk of bleeding.
Choice D rationale
DIC is not controllable with lifelong heparin usage. While heparin may be used in certain cases to manage DIC, it is not a lifelong treatment. The management of DIC focuses on treating the underlying cause and supporting the patient through the acute phase of the disorder.
Correct Answer is D
Explanation
Choice A rationale
Instructing to slowly exhale with pursed lips is a breathing technique but not the first action to take before the procedure.
Choice B rationale
Assessing pulse and respirations is important but not the first action to take before the procedure.
Choice C rationale
Assessing characteristics of her sputum is important but not the first action to take before the procedure.
Choice D rationale
Auscultating lung fields is the first action to take to assess the client’s current respiratory status and determine the effectiveness of the upcoming procedure. .
