Elevate casted arm when resting and when sitting up.

Swelling of the fingers is to be expected for the next 48 hours.

Allow the affected limb to hang down for 1 hour each day.

Answer and Explanation

The Correct Answer is A

A. Elevating the casted arm helps reduce swelling and promotes circulation. The arm should be elevated above the heart level when resting to minimize swelling.

B. Immobilizing the shoulder is unnecessary unless specifically instructed, as immobilizing the shoulder is not required for most arm fractures.

C. Swelling of the fingers can occur with a cast, but it should not last longer than 24 hours. Prolonged swelling should be reported.

D. Allowing the limb to hang down may increase swelling and should be avoided.

Correct Answer is ["B","D","E"]

Explanation

A. Sickled cells are rigid, not flexible, making it harder for them to pass through small vessels.

B. Sickled red blood cells are crescent or "c" shaped and have an increased tendency to clump together, which obstructs blood flow.

C. Sickled cells have a short lifespan, so they do not circulate longer than healthy cells.

D. Sickled cells are rigid, making it difficult for them to pass through small blood vessels, leading to blockages and reduced oxygen delivery.

E. Sickled red blood cells have a shorter lifespan (about 10-20 days compared to the normal 120 days), leading to anemia and a decreased number of circulating red blood cells.

A. Urinary output 100 mL/hr B. Temperature 39.1C (102.4° F) C. Blood pressure 130/90 mm Hg D. Heart ráte 60/min

Correct Answer is B

Explanation

A. A urinary output of 100 mL/hr is within the expected range for a 10-year-old and does not indicate septic shock. In early septic shock, urinary output is often preserved or mildly decreased.

B. An elevated temperature (fever) is a hallmark of early septic shock as the body mounts an inflammatory response to infection. Fever often accompanies early sepsis in pediatric patients.

C. Blood pressure may remain normal or slightly elevated in early septic shock due to compensatory mechanisms. A BP of 130/90 mm Hg is not a defining feature.

D. A heart rate of 60/min is abnormally low for a 10-year-old and could indicate late-stage shock or other complications. In early septic shock, tachycardia (elevated heart rate) is typically observed.
