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 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.

A. "I will place a bath seat in my shower to use when I bathe." B. "I will place an area rug at the entry of my bathroom." C. "I will keep my walker at the end of my bed." D. "I will keep the fluorescent ceiling light on in my room at night."

Correct Answer is A

Explanation

A. Placing a bath seat in the shower is a safety measure to prevent falls while bathing. This statement indicates an understanding of the importance of bathroom safety.

B. Placing an area rug at the entry of the bathroom can actually increase the risk of falls, as rugs can be tripping hazards. This statement does not demonstrate an understanding of home safety.

C. Keeping the walker at the end of the bed is a good practice for easy access, but it doesn't specifically address fall prevention in the home.

D. Keeping the fluorescent ceiling light on at night can provide better visibility and reduce the risk of tripping, but it doesn't address specific fall prevention measures elsewhere in the home.
