Correct Answer: C

Rationale: Measuring the stoma using a stoma guide (C) is crucial as it ensures that the appliance fits properly, which is essential for preventing skin irritation and leakage. Proper measurement helps in selecting the right size of the appliance, promoting comfort and optimal stoma care. In contrast, cleansing with hydrogen peroxide (A), applying a moisture barrier cream (B), and using a dry gauze pad (D) are important but not as critical as ensuring the correct fit of the stoma appliance.

Correct Answer: D

Rationale: If resistance is encountered, the nurse should discontinue the procedure and notify the physician, as this may indicate an obstruction.

Correct Answer: D

Rationale: The statement 'I should continue taking my over-the-counter herbal supplements' (D) indicates a need for further teaching because some herbal supplements can interact with anticoagulants, increasing the risk of bleeding. It is crucial to inform healthcare providers about all medications, including herbal supplements, to prevent adverse interactions. The other statements reflect appropriate understanding of precautions related to DVT and anticoagulation therapy.

Correct Answer: A

Rationale: In this situation, the most important action for the nurse to implement is to instruct the client to repeat the medication plan. By using the teach-back method, the nurse can ensure the client's understanding of the prescribed medications and address any concerns or anxieties the client may have. This approach promotes patient engagement, active participation, and retention of important information, ultimately enhancing medication adherence and safety.

Correct Answer: B

Rationale: To evaluate the effectiveness of epoetin alfa (Epogen) in treating anemia, the nurse should monitor hemoglobin and hematocrit levels. These values indicate the oxygen-carrying capacity of the blood, which directly relates to the treatment of anemia. White blood cell count (A), platelet count (C), and blood urea nitrogen (BUN) and creatinine (D) are not specific indicators of the effectiveness of epoetin alfa in treating anemia.
