The nurse is assisting in the administration of IV vancomycin to a client who has methicillin-resistant Staphylococcus aureus (MRSA). Which of the following findings indicate an allergic reaction to the medication?

Rationale:

A. Encourage the client to increase fluid intake: Clients receiving continuous peritoneal dialysis may need to restrict fluids to prevent volume overload, depending on residual kidney function and dialysis efficiency. Encouraging increased intake without provider orders can be harmful.

B. Obtain the client's weight: Daily weight is a critical indicator of fluid balance and dialysis effectiveness. Monitoring weight helps determine if the dialysis is removing the appropriate amount of fluid and supports adjustments to the treatment plan.

C. Palpate the access site for a thrill: A thrill is a vibration felt over an arteriovenous fistula, which is used in hemodialysis, not peritoneal dialysis. Peritoneal dialysis uses a soft catheter in the abdomen and does not produce a thrill.

D. Auscultate the access site for a bruit: A bruit, a whooshing sound heard over a vascular access, is associated with AV fistulas used in hemodialysis. It is not relevant for peritoneal dialysis, which uses a catheter and does not involve high-pressure blood flow.

Rationale:
• Urinary stasis: Immobility slows bladder emptying and ureteral flow, increasing residual urine. This promotes bacterial growth and risk of urinary tract infection. MS clients with decreased mobility are especially vulnerable.

• Calcium resorption: Bone demineralization occurs during prolonged immobility. Without weight-bearing, calcium is released from bone into the bloodstream, raising serum calcium and weakening bones.

• Contractures: Lack of movement leads to shortening and stiffening of muscles and joints. Over time, joints lose flexibility, especially if the client remains curled in one position.

• Hypocalcemia: The client is more likely to develop hypercalcemia due to calcium resorption from bones. There's no evidence of low calcium symptoms like tetany or numbness.

• Hypertension: The client's vital signs are within normal range. Immobility may reduce cardiac output over time, but it does not typically cause high blood pressure.

• Diarrhea: Immobility usually causes constipation due to slowed peristalsis. There's no report of active GI symptoms or triggers for diarrhea in this case.

• Pressure ulcer: Continuous pressure on one area reduces capillary blood flow. This leads to tissue ischemia and skin breakdown, especially over bony prominences like the hip and shoulder.

• Atelectasis: Lying on one side restricts lung expansion, and refusal to change positions impairs ventilation. This can cause alveolar collapse and decreased oxygen exchange.
