A nurse needs to infuse three 1L bags over 12 hours. At what rate should the nurse program the pump to run in millilitres per hour?
(Round to the nearest whole number.)

A. Performing range of motion:
Explanation: Range of motion exercises are important for preventing joint stiffness and muscle atrophy, especially in clients with casts. However, this is not the first priority. Ensuring adequate circulation and perfusion is crucial before initiating any exercises or movements, as compromised circulation could lead to serious complications.

B. Managing pain:
Explanation: Pain management is important for the client's comfort, but it is not the first priority in this context. Assessing circulation and ensuring there are no signs of compromised perfusion takes precedence. Pain management can follow once circulation has been confirmed as adequate.

C. Checking capillary refill:
Explanation: Checking capillary refill is the first priority when assessing a client with a cast. Capillary refill assesses peripheral circulation by pressing on the nail bed and observing how quickly color returns. Delayed capillary refill could indicate compromised blood flow, which is a serious concern and requires immediate intervention.

D. Discussing cast care:
Explanation: Educating the client about cast care is important, but it is not the first priority. Ensuring proper circulation and ruling out any signs of impaired perfusion must be addressed before discussing cast care instructions.

A. Urine culture and sensitivity
Explanation: A urine culture and sensitivity test involves growing bacteria from a urine sample in a laboratory setting. Once the bacteria have grown, they are exposed to different antibiotics to see which one is most effective in inhibiting their growth. This helps healthcare providers identify the specific strain of bacteria causing the infection and choose the most appropriate antibiotic treatment.

B. Serum creatinine level
Explanation: Serum creatinine level is a blood test used to measure kidney function. It evaluates how well the kidneys are filtering waste from the blood. While important for assessing kidney health, it does not determine the specific bacteria causing a urinary tract infection or the appropriate antibiotic treatment.

C. Urinalysis
Explanation: Urinalysis is a broad screening test that assesses various components in the urine, such as red and white blood cells, protein, glucose, and bacteria. While it can detect signs of a urinary tract infection (such as the presence of bacteria and white blood cells), it does not identify the specific bacterial strain causing the infection or provide information about antibiotic sensitivity.

D. Kidney scan
Explanation: A kidney scan, also known as a renal scan, is a medical imaging technique used to assess the structure and function of the kidneys. It can help diagnose conditions like kidney stones, urinary obstruction, or kidney infections. However, it does not determine the strain of bacteria causing a urinary tract infection or guide antibiotic treatment.
