Correct Answer: B

Rationale: The correct answer is B: Mouth sores. Mouth sores are a common side effect of radiation therapy, especially when the treatment is focused on the head or neck area. Weight gain is not typically associated with radiation therapy; instead, clients may experience weight loss due to side effects like nausea and loss of appetite. Hyperpigmentation is not a common finding related to radiation therapy. Increased saliva production is not a typical side effect of radiation therapy; instead, clients may experience dry mouth.

Correct Answer: A

Rationale: Placing a pillow between the client's legs is the correct action to prevent dislocation of the prosthesis after hip arthroplasty. This positioning helps maintain proper alignment and stability of the hip joint, reducing the risk of dislocation. Placing the client in a high Fowler's position (choice B) is not recommended after hip arthroplasty as it may strain the hip joint. Maintaining the client in a side-lying position (choice C) or keeping the client's legs elevated (choice D) does not provide the same level of support and alignment as placing a pillow between the legs.

Correct Answer: D

Rationale: The correct answer is D. A productive cough with green sputum can indicate a bacterial infection, which is a concern for clients with COPD. Reporting this finding to the provider is important for further evaluation and management. Choices A, B, and C are not as concerning in the context of COPD management. An oxygen saturation of 92% is within an acceptable range for COPD patients, pursed-lip breathing is a helpful technique for managing breathing difficulties in COPD, and an increased anterior-posterior chest diameter is a common finding in clients with COPD due to chronic air trapping.

Correct Answer: C

Rationale: The correct answer is C: 'Avoid eating spicy foods.' Spicy foods can exacerbate symptoms of GERD by irritating the esophagus and causing discomfort. It is important for clients with GERD to avoid spicy foods to help manage their condition. Choices A, B, and D are incorrect. A client with GERD should not lie down after meals as this can worsen symptoms, limiting fluid intake to only 1 liter per day may not be appropriate for everyone, and eating three large meals each day can put pressure on the stomach and worsen GERD symptoms.

Correct Answer: A

Rationale: Assessing the surgical site is crucial in identifying early signs of infection post-surgery. Changes such as redness, swelling, warmth, or drainage may indicate an infection developing. While monitoring vital signs and fever are important in infection assessment, they are general indicators and may not show localized signs at the surgical site. Checking for abnormal breath sounds is more relevant when assessing respiratory issues rather than infection at the surgical site.
