Correct Answer: D

Rationale: A saturated abdominal dressing may indicate active bleeding or other complications that require immediate intervention, such as ensuring hemostasis and preventing further complications. Absent bowel sounds are common in the immediate post-operative period and may not require immediate intervention unless accompanied by other symptoms. A pain level of 8/10 can be managed with appropriate pain medication and is not typically considered an immediate priority unless other indications suggest complications. A temperature of 100.4°F is slightly elevated but may not be a cause for immediate concern unless it is associated with other signs of infection or distress that would warrant urgent attention.

Correct Answer: A

Rationale: The appropriate nursing action when an irregularity in the heart rate is observed is to count the apical pulse rate for a full minute and describe the rhythm in the chart. This approach helps in obtaining an accurate assessment of the irregularities present. Measuring the blood pressure (Choice B) is important but not the immediate priority when an irregular heart rate is noted. Performing an ECG (Choice C) may be necessary but is a more advanced intervention that should follow the initial assessment. Rechecking the heart rate after 5 minutes (Choice D) may delay potential interventions for addressing the irregularity, making it less appropriate than the immediate assessment and documentation of the pulse rhythm.

Correct Answer: D

Rationale: Discontinuing the infusion is the first step in addressing potential complications such as phlebitis or infection. It is crucial to prevent further infusion-related damage by stopping the source of the issue. Obtaining a specimen for culture (Choice A) can be considered later to identify the specific microorganism causing the infection. Applying a warm compress (Choice B) or administering analgesics (Choice C) may provide comfort but do not address the underlying issue of infection or phlebitis, which requires immediate intervention by discontinuing the infusion.

Correct Answer: B

Rationale: The correct answer is B: Hemoglobin. Epoetin alfa (Epogen) is a medication commonly used in clients with chronic kidney disease to stimulate red blood cell production. Monitoring hemoglobin levels is crucial to assess the effectiveness of epoetin alfa therapy. Hemoglobin levels reflect the oxygen-carrying capacity of the blood and indicate if the medication is successfully treating anemia associated with chronic kidney disease. Option A, serum creatinine, is a marker of kidney function, not the primary indicator of epoetin alfa effectiveness. Option C, blood urea nitrogen (BUN), is a measure of kidney function and hydration status. Option D, platelet count, assesses clotting ability and is unrelated to monitoring the effectiveness of epoetin alfa in treating anemia in chronic kidney disease.

Correct Answer: A

Rationale: The correct answer is A: Hydrocolloid. Hydrocolloid dressings are recommended for stage 2 pressure injuries as they help maintain a moist wound environment, which supports the healing process. Gauze (choice B) is not ideal for stage 2 pressure injuries as it can stick to the wound bed and disrupt the healing process. Transparent film dressings (choice C) are more suitable for superficial wounds or as a secondary dressing. Alginate dressings (choice D) are typically used for wounds with heavy exudate, which is not typically seen in stage 2 pressure injuries.
