Answer and Explanation

The Correct Answer is ["32"]

1. Determine the concentration of heparin in the solution:

- There are 25,000 units of heparin in 500 mL of D5W.

- Concentration = 25,000 units / 500 mL = 50 units/mL.

2. Calculate the required mL/hr for the desired infusion rate:

- The order is for 1600 units/hr.

- To find the mL/hr:

ML/HR=desired units/hr divided by unts/ml

=1600/50

=32ml/hr

Correct Answer is B

Explanation

A. This statement is incorrect. Drying time is actually shorter with a synthetic cast compared to a plaster cast. Synthetic casts use a chemical reaction for hardening, which typically sets faster than the drying process of plaster.

B. Correct. A synthetic cast is generally lighter in weight compared to a plaster cast. This can be more comfortable for the patient and may provide better mobility.

C. This statement is incorrect. Plaster casts do not necessarily require expensive equipment for application. Both types of casts require appropriate materials and training for application, but cost can vary based on factors like the type of material and the specific clinical setting.

D. This statement is incorrect. Both plaster and synthetic casts are effective for immobilizing bone fractures when applied correctly. The choice between the two often depends on factors such as the type of fracture, patient comfort, and clinician preference.

A. Transverse B. Oblique C. Impacted D. Comminuted

Correct Answer is D

Explanation

A. Transverse fractures occur straight across the bone. In this case, the bone is splintered, which is not characteristic of a transverse fracture.

B. Oblique fractures have a diagonal break across the bone. This does not match the description provided in the scenario.

C. Impacted fractures occur when one end of the bone is forced into the adjacent bone. This does not align with the description of the fracture in the scenario.

D. Correct. A comminuted fracture involves the bone breaking into multiple fragments or pieces. This aligns with the description provided in the scenario where the bone is splintered into several pieces around the shaft.
