Correct Answer: D

Rationale: Hair loss is the correct answer. Teens are often more concerned about hair loss because of its visible impact and social implications. While mouth sores, fatigue, and diarrhea are also common side effects of chemotherapy, hair loss tends to be a significant concern for teens due to its effect on self-image and confidence.

Correct Answer: B

Rationale: The correct answer is B: 'get the description of the location and intensity of the pain.' When a client complains of pain, the initial step in pain assessment is to gather information about the location and intensity of the pain. This helps the nurse understand the nature of the pain and lays the groundwork for further assessment and management. Choice A is incorrect because identifying coping methods comes later in the assessment process. Choice C is incorrect as accepting the client's report of pain is important, but not the first step. Choice D is incorrect as determining the client's pain status also comes after gathering information about the pain.

Correct Answer: C

Rationale: Dyspnea indicates a potential complication such as pneumothorax or incorrect catheter placement, requiring immediate attention. Pallor may indicate anemia but is not as urgent as dyspnea in this context. Increased temperature could be a sign of infection but is not as critical as respiratory distress. Involuntary muscle spasms are not directly related to central venous catheter placement and are of lower priority compared to respiratory issues.

Correct Answer: C

Rationale: When evaluating the therapeutic effectiveness of digoxin in a client with heart failure, the nurse should expect to find improved respiratory status and increased urinary output. Digoxin helps improve cardiac output and reduces fluid accumulation, leading to improved breathing and increased urinary output. Choices A, B, and D are incorrect because diaphoresis with decreased urinary output, increased heart rate with increased respirations, and decreased chest pain with decreased blood pressure are not indicative of the therapeutic effectiveness of digoxin in heart failure management.

Correct Answer: D
