Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Potassium is typically administered on a secondary line to prevent rapid infusion and potential adverse effects. 2. The primary line carries the D5 ½ NS solution without potassium, while the secondary line delivers the potassium. 3. Reporting that "potassium is on the secondary line" accurately describes the setup for this IV infusion. Summary: A: Incorrect - Incorrectly states that the potassium bag is piggybacked into the dextrose. B: Incorrect - Closing the clamp below the D5 ½ NS bag is unnecessary and does not address the potassium infusion. D: Incorrect - Fails to address the specific issue of the potassium infusion being on a secondary line.

Correct Answer: D

Rationale: The correct answer is D: Evaluation. After implementing nursing interventions based on priority diagnoses, the nurse must evaluate the effectiveness of these interventions to determine if the desired outcomes have been achieved. Evaluation is crucial to assess the progress, make necessary modifications, and ensure the effectiveness of the care provided. Assessment (A) is already completed before interventions are carried out. Planning (B) involves developing a care plan based on assessment findings. Implementation (C) is the actual carrying out of the interventions. Therefore, the next step after implementing nursing interventions is to evaluate their effectiveness.

Correct Answer: E

Rationale: The correct answer is missing from the choices provided. However, for a client with an immune system disorder, essential nursing actions include: E: Educate the client on the importance of maintaining a healthy lifestyle, avoiding exposure to infections, and adhering to prescribed medications. This is crucial for managing the immune system disorder effectively. Incorrect choices: A: Following agency guidelines is important but doesn't specifically address the client's immune system disorder. B: Reviewing drug references may be necessary but is not a priority in managing the immune system disorder. C: Advising the client on modifying the home environment is not directly related to managing the immune system disorder. D: Monitoring the client for depression is important but not specific to addressing the immune system disorder.

D: Incorrect - Fails to address the specific issue of the potassium infusion being on a secondary line.

Correct Answer: B

Rationale: The correct answer is B: radiation therapy. Radiation therapy uses high-energy radiation to target and destroy cancer cells while minimizing damage to surrounding healthy tissues. It is a localized treatment that is effective in shrinking tumors and preventing cancer cell growth. Surgery (A) involves physically removing the tumor and surrounding tissues, while chemotherapy (C) uses drugs to kill cancer cells throughout the body. Palliative treatment (D) focuses on symptom management and improving quality of life in advanced stages of cancer. In this case, the focus is on a form of cancer therapy involving high-energy electromagnetic radiation, making radiation therapy the most appropriate choice.
