The nurse is caring for a client who has disseminated intravascular coagulation (DIC). The healthcare provider prescribes an infusion of heparin. Based on the protocol, the initial dose is 14 units/kg/hr. The heparin is dispensed at a concentration of 25,000 units/250 ml. The client weighs 79.1 kg. How many mL/hr will the nurse set the Infusion pump? (Round the rate to nearest tenth. Only enter numbers and decimals. Do not enter any letters in your answer.)

Answer and Explanation

The Correct Answer is ["11.074"]

To calculate the infusion rate, we'll use the following formula:

Infusion rate (mL/hr) = Desired dose (units/hr) / Concentration of heparin (units/mL)

First, calculate the desired dose in units/hr:

14 units/kg/hr x 79.1 kg = 1107.4 units/hr

Next, calculate the concentration of heparin in the IV bag:

25,000 units / 250 mL = 100 units/mL

Finally, plug the values into the formula:

Infusion rate = 1107.4 units/hr / 100 units/mL = 11.074 mL/hr

Correct Answer is A

Explanation

A. Performing hand hygiene before, during, and after direct contact with the client is the most effective strategy for preventing the transmission of infections. Hand hygiene interrupts the transmission of pathogens and is a cornerstone of infection control practices.
B. Changing the client's bed linens each day is a standard practice for maintaining cleanliness but does not specifically prevent infection transmission. The primary goal of infection control is to reduce pathogen transmission rather than just maintaining general cleanliness.
C. Controlling the client's blood glucose level is important for overall health and wound healing but does not directly prevent infection transmission. It is not an infection control strategy.
D. Placing the client in a room with positive-pressure airflow is used to protect immunocompromised patients from infections by preventing outside air from entering the room. However, it is not appropriate for preventing the transmission of an infection from a client to others.

A. Decreased prothrombin time B. Increased hematocrit C. Increased sodium D. Potassium deficit

Correct Answer is B

Explanation

A. Decreased prothrombin time is not typically associated with the emergent phase of a burn injury. Prothrombin time changes are more related to liver function or coagulation disorders.
B. Increased hematocrit is common in the emergent/resuscitative phase of burn injury due to fluid shifts and loss of plasma volume, leading to hemoconcentration.
C. Increased sodium is not typically seen in the emergent phase; instead, hyponatremia may occur due to fluid shifts and loss of sodium in the burn exudate.
D. Potassium deficit is more likely to occur later in the burn management phases. In the emergent phase, hyperkalemia is more common due to cell destruction and release of intracellular potassium.
