Correct Answer: A

Rationale: The correct adverse effect that the nurse should include in the teaching is fatigue. Fatigue is a common side effect of radiation therapy, particularly with prolonged treatment. Constipation, hair loss, and weight gain are not typically associated with radiation therapy for breast cancer, making them incorrect choices. Fatigue can significantly impact a patient's quality of life during treatment and should be addressed proactively by healthcare providers.

Correct Answer: A

Rationale: The correct answer is A: Pain Management. After abdominal surgery, one of the primary goals of post-operative care is to manage the patient's pain effectively to ensure their comfort and promote recovery. While wound care, prevention of complications, and ensuring digestive function are also important aspects of post-operative care, pain management takes precedence as it directly impacts the patient's well-being and recovery process.

Correct Answer: A

Rationale: Assessing mobility should be the nurse's priority as it ensures the client's safety and helps in developing an appropriate care plan. By evaluating the client's ability to move after the knee arthroplasty, the nurse can identify any immediate issues or complications that need to be addressed promptly. Monitoring vital signs, providing pain relief, and reinforcing discharge teaching are important aspects of care but assessing mobility takes precedence in ensuring the client's immediate well-being and identifying any potential risks.

Correct Answer: D

Rationale: When a patient is receiving IV potassium, it is crucial to monitor various parameters to ensure patient safety. Monitoring the ECG helps in identifying any potential dysrhythmias that may occur due to potassium imbalances. Monitoring urine output is important as potassium levels can affect renal function. Monitoring serum potassium levels is essential to assess the effectiveness of the IV potassium therapy. Therefore, all the options - monitoring ECG for dysrhythmias, urine output, and serum potassium levels - are necessary when administering IV potassium, making 'All of the above' the correct answer. Choices A, B, and C are not individually sufficient as they each address different aspects of patient monitoring when receiving IV potassium.

Correct Answer: D

Rationale: The primary intervention for sepsis involves a multifaceted approach, including administering IV antibiotics to address the underlying infection and administering fluids to stabilize the patient's hemodynamic status. Monitoring blood pressure is important in the management of sepsis, but it is not the sole primary intervention. Therefore, the correct answer is 'All of the above' as it encompasses the comprehensive approach required for effective sepsis management.
