A nurse is teaching a client who is pregnant and has iron-deficiency anemia about taking ferrous sulfate elixir, Which of the following instructions should the nurse include in the teaching? (Select all that apply.)

A. INR (International Normalized Ratio): INR is a measure of blood clotting and is not directly affected by filgrastim, which stimulates the production of white blood cells. Monitoring INR is more relevant when assessing anticoagulant therapy.
B. Potassium level: Filgrastim does not directly influence potassium levels. Monitoring potassium is important for certain medications and conditions, but it is not the primary parameter to evaluate the effectiveness of filgrastim.
C. WBC count: Filgrastim (granulocyte colony-stimulating factor) is used to stimulate the production of white blood cells, specifically neutrophils. Monitoring the white blood cell count is crucial in evaluating the effectiveness of filgrastim treatment. An increase in the WBC count, particularly the neutrophil count, indicates a positive response to the medication.
D. BUN (Blood Urea Nitrogen): BUN is a measure of kidney function and is not directly influenced by filgrastim. While monitoring kidney function is important in general patient care, it is not the primary parameter to assess the effectiveness of filgrastim.

A. Increased blood pressure: Heparin does not typically directly affect blood pressure. However, if there are other underlying conditions or complications related to the reason for heparin use, it might indirectly influence blood pressure. But a high aPTT level itself wouldn't directly cause an increase in blood pressure.
B. Decreased temperature: Heparin does not usually affect body temperature. Changes in temperature might occur due to other factors, but they are not directly related to heparin administration or its effects on aPTT.
C. Decreased respiratory rate: Heparin does not typically affect the respiratory rate directly. Changes in respiratory rate might occur due to other causes but are not directly correlated with heparin administration or its effects on aPTT.
D. Increased pulse rate: Heparin, especially when aPTT is elevated, might indicate that the blood is less likely to clot. An increased pulse rate could be indicative of compensatory mechanisms due to potential bleeding or changes in clotting factors influenced by heparin. It's essential to monitor for an increased pulse rate as a potential sign of bleeding complications associated with anticoagulant therapy.
