The nurse understands the purpose of Heparin (anticoagulant) therapy in treating deep vein thrombosis is to:

Dissolve the thrombus

Reestablish blood flow

Reduce vein inflammation

Inhibit clot formation

Answer and Explanation

The Correct Answer is D

A. Dissolve the thrombus: Heparin does not have the ability to break down or dissolve existing blood clots. Instead, it works to prevent the clot from growing larger or new clots from forming. Clot dissolution is achieved by other medications such as thrombolytics.

B. Reestablish blood flow: While the ultimate goal is to restore proper circulation, Heparin itself does not actively reopen blocked vessels. It works by stopping further clot formation, which can indirectly help improve blood flow over time.

C. Reduce vein inflammation: Heparin is not an anti-inflammatory medication and does not reduce inflammation in the veins. Its primary function is anticoagulation to prevent clot propagation rather than treating inflammation directly.

D. Inhibit clot formation: Heparin acts as an anticoagulant by interfering with the blood clotting process, particularly thrombin and factor Xa, preventing new clots from forming and existing clots from getting bigger. This is the main therapeutic purpose in treating DVT.

Correct Answer is A

Explanation

A. Sign each entry: Proper documentation requires each entry to be signed or initialed by the nurse to verify accountability and provide a clear record of who performed the care. This is essential for legal and professional standards.

B. Leave blank spaces in charting: Leaving blank spaces can lead to unauthorized additions or confusion and is discouraged. Documentation should be continuous and clear without gaps to maintain accuracy and integrity.

C. Identify each entry with AM/PM instead of military time (2400 hour cycle): Military time is a standard and accepted practice in healthcare settings for clarity and to avoid confusion between AM and PM. Changing to AM/PM is unnecessary and may increase error risk.

D. Use different color of ink to highlight medication administration: Using different ink colors is not a standard requirement and could complicate documentation consistency. Clear, legible, and accurate entries are more important than color coding.

Correct Answer is ["10"]

Explanation

Desired Dose: 500 mg

Available Concentration: 250 mg per 5 ml

Volume = (Desired Dose / Available Concentration in mg) ´ Volume per Concentration

= (500 mg / 250 mg) ´ 5 ml

= 2 ´ 5 ml

= 10 ml
