Correct Answer: A

Rationale: The correct answer is A: Increased white blood cell count. When a client has an infection, the body's immune response triggers an increase in white blood cells to help fight off the infection. Neutrophils and band cells (choice B) may also increase during infection, but a general increase in white blood cells is a more reliable indicator. ESR (choice C) is a nonspecific marker of inflammation and may be elevated in various conditions, not just infection. LDH (choice D) is an enzyme found in many tissues and can be elevated in various conditions, not specifically infection. Therefore, an increased white blood cell count is the most indicative of infection in a client with a fever.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics. This is the most appropriate intervention for a wound infection as antibiotics target the underlying bacterial infection causing the wound infection. Antibiotics help to eliminate the infection and prevent it from spreading further. Administering antibiotics is crucial in treating wound infections to promote healing and prevent complications. Choice B (Apply sterile dressing) is incorrect as simply applying a sterile dressing does not address the underlying infection. Choice C (Cleanse and dress the wound) is also incorrect because while wound cleansing is important, it alone may not be sufficient to treat a wound infection. Choice D (Administer analgesics) is incorrect because analgesics only provide pain relief and do not address the infection itself.

Correct Answer: B

Rationale: The correct answer is B: Sedation. Cancer patients taking opioids commonly experience sedation due to the central nervous system depressant effects of opioids. Opioids can cause drowsiness, fatigue, and decreased alertness. Tolerance (A) is a possible issue but is not the most common complication. Addiction (C) is less common in cancer patients due to the nature of their pain management. Constipation (D) is a common side effect of opioids but is not the most common complication in cancer patients. Sedation is the most prevalent issue affecting the quality of life and daily functioning of cancer patients on opioids.

Correct Answer: A

Rationale: The correct answer is A: Administer oxygen. In acute shortness of breath with COPD, oxygen therapy is crucial to improve oxygenation levels and alleviate respiratory distress. Oxygen can help reduce the workload on the lungs and heart. Antibiotics (B) are not indicated unless there is a suspected bacterial infection. Monitoring blood glucose (C) is important in diabetes management but not the priority in acute respiratory distress. Administering pain relief (D) may not address the underlying cause of the shortness of breath. Oxygen therapy directly targets the respiratory issue in COPD exacerbation, making it the most effective initial intervention.

Correct Answer: C

Rationale: Rationale: C: Reinforce the dressing is the correct intervention for serosanguineous drainage after cholecystectomy. This helps maintain a clean and dry wound environment, promotes healing, and prevents infection. Changing the dressing (B) may disrupt the wound healing process. Notifying the physician (A) is important but not the immediate intervention. Applying an abdominal binder (D) is not indicated for managing serosanguineous drainage.
