What is the best method to prevent the spread of infection to others when the nurse is changing the dressing over a wound infected with Staphylococcus aureus?

Correct Answer: C

Rationale: The correct answer is C: Wash hands and properly dispose of soiled dressings. This is the best method to prevent the spread of infection when changing the dressing over a wound infected with Staphylococcus aureus. Washing hands helps to remove any potential pathogens, reducing the risk of cross-contamination. Proper disposal of soiled dressings ensures that any infectious material is contained and not spread to others. Incorrect options: A: Changing the dressing using sterile gloves is important, but it is not sufficient on its own to prevent the spread of infection. B: Applying antibiotic ointment over the wound may help treat the infection locally but does not address the risk of spreading the infection. D: Soaking the dressing in sterile normal saline before removal may help with the removal process, but it does not address preventing the spread of infection to others.

Correct Answer: C

Rationale: The correct answer is C because observing the patient's body build and muscle configuration provides initial information about the patient's overall musculoskeletal health. This step allows the nurse to assess for any abnormalities, such as muscle atrophy or asymmetry, which can indicate underlying musculoskeletal issues. It also helps in identifying any deformities or structural abnormalities. Choice A is incorrect because having the patient move the extremities against resistance comes later in the assessment process to evaluate muscle strength. Choice B is incorrect as feeling for crepitus during joint movement is a specific assessment for joint health and does not address the overall musculoskeletal system. Choice D is incorrect as checking active and passive range of motion for the extremities is typically done after observing the patient's body build and muscle configuration.

Correct Answer: D

Rationale: Correct Answer: D - Modifying arm movements Rationale: Modifying arm movements is crucial in managing repetitive strain syndrome to prevent further damage and alleviate symptoms. This approach focuses on changing the way the worker performs tasks to reduce strain on the affected area. By teaching the patient how to adjust their movements, the nurse can help prevent exacerbation of symptoms and promote healing. Summary: A: Surgical options are not typically the first-line treatment for repetitive strain syndrome and are usually considered only when conservative measures have failed. B: Elbow injections may provide temporary relief but do not address the root cause of the issue, which is repetitive strain from improper movements. C: Wearing a left wrist splint may provide support but does not address the root cause of the issue, which is the strain on the elbow from repetitive movements.

Correct Answer: B

Rationale: The correct answer is B because it demonstrates proper crutch walking technique. By advancing the left leg and both crutches together first, the patient maintains non-weight bearing on the left leg. Then, advancing the right leg allows for a smooth and balanced gait pattern. Choice A is incorrect because it would result in weight-bearing on the left leg when the right crutch is moved with the right leg. Choice C is incorrect as the patient should not rely on external support like a bedside chair for balance during ambulation. Choice D is incorrect as the crutch should not be placed firmly in the axillary area to avoid nerve damage.

Correct Answer: B

Rationale: The correct answer is B because lying flat on the abdomen helps prevent hip flexion contractures after an above-the-knee amputation. This position stretches the hip flexors and prevents shortening of these muscles, maintaining flexibility. It also facilitates proper alignment of the residual limb, reducing the risk of contractures. Choices A, C, and D are incorrect. A: Elevating the residual limb on a pillow is not the most effective way to prevent contractures. C: Changing the limb sock is important for hygiene but not directly related to preventing contractures. D: Using lotion on the stump is beneficial for skin care but does not address the prevention of contractures.
