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 IV fluids. This is the most important nursing intervention for a client with severe dehydration because IV fluids provide rapid rehydration and help restore electrolyte balance efficiently. Monitoring vital signs (choice B) is important but not as crucial as providing immediate fluid replacement. Providing oral rehydration (choice C) may not be effective for severe dehydration as the client may have difficulty absorbing fluids orally. Administering oxygen (choice D) is not directly related to treating dehydration, so it is not the most important intervention in this scenario.

Correct Answer: B

Rationale: The correct answer is B: Monitor for arrhythmias. This is because in a client showing signs of shock after surgery, the priority is to assess for any cardiac complications such as arrhythmias, which can be life-threatening. Monitoring for arrhythmias allows prompt identification and intervention. Administering a blood transfusion (A) may be necessary in some cases of shock but is not the first intervention. Administering oxygen (C) may also be necessary, but addressing cardiac complications takes precedence. Encouraging deep breathing (D) is not a priority in managing shock-related complications.

Correct Answer: A

Rationale: The correct answer is A: Turn the client every two hours. This action helps prevent pressure ulcers by relieving pressure on specific areas of the body. Turning the client redistributes pressure, promotes circulation, and reduces the risk of tissue damage. It is a crucial part of pressure ulcer prevention in immobile or bedridden patients. Increasing protein intake (B) may aid in wound healing but does not directly prevent pressure ulcers. Encouraging rest (C) may not address the root cause of pressure ulcers. Applying dressings to wounds (D) is a treatment for existing ulcers, not prevention.

Correct Answer: A

Rationale: The correct answer is A: Immobilize the spine. This is the first priority because it helps prevent further injury to the spinal cord. By immobilizing the spine, the nurse ensures that any movement doesn't worsen the existing injury. Placing the client in a supine position (B) can be done after immobilization. Administering analgesics (C) should not be done before assessing the extent of the injury. Assessing the airway (D) is important but should come after immobilizing the spine to prevent any unnecessary movement.
