Correct Answer: A

Rationale: When assessing a patient with a suspected infection, it is crucial to monitor temperature and check for elevated white blood cells. Elevated temperature indicates a potential infection, and increased white blood cells are a sign of inflammation and the body's response to an infection. Monitoring blood pressure (choice B) and checking for fever (choice B) are not as specific indicators of infection as monitoring temperature and white blood cell count. Assessing changes in mental status and monitoring urine output (choice C) are important aspects of patient assessment but may not directly indicate a suspected infection. Administering antibiotics (choice D) should only be done after a confirmed diagnosis of a bacterial infection, as unnecessary antibiotic use can lead to antibiotic resistance and other adverse effects.

Correct Answer: C

Rationale: Applying an orthotic to the client's foot is the appropriate intervention to prevent contractures in an immobile client. An orthotic helps maintain proper alignment and prevents the development of contractures by keeping the foot in the correct position. Choices A, B, and D are incorrect because a trochanter wedge, towel roll under the neck, and pillow under the knees are not specific interventions for preventing contractures in an immobile client.

Correct Answer: A

Rationale: The appropriate action for a healthcare professional when administering a blood transfusion is to verify the patient's identity. This step is essential to ensure that the correct blood product is given to the right patient, preventing any errors or adverse reactions. While monitoring vital signs and staying with the patient during the initial phase of the transfusion are also important steps, the primary action of verifying the patient's identity takes precedence to uphold patient safety and prevent any potential harm.

Correct Answer: B

Rationale: Performing a wound culture before administering antibiotics is crucial in identifying the specific infecting organism and choosing the most effective antibiotic treatment. Changing the dressing every 4 hours (choice A) may be too frequent and can disrupt the wound healing process. Cleansing the wound with alcohol-based solutions (choice C) can be too harsh and may delay healing. Applying a wet-to-dry dressing (choice D) can cause trauma to the wound bed and is not recommended for infected wounds.

Correct Answer: C

Rationale: The correct answer is to hold your breath for 5-10 seconds after inhaling when using a metered-dose inhaler (MDI) for asthma management. This action ensures proper medication absorption in the lungs. Inhaling rapidly (choice A) may cause the medication to impact the mouth/throat rather than the lungs. Exhaling completely before inhalation (choice B) does not optimize medication delivery. Inhaling slowly (choice D) may not allow the medication to reach the lungs effectively.
