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 D

Explanation

A. Anuria, or the absence of urine output, occurs in later stages of shock when there is significant renal hypoperfusion. It is not an early indicator of shock.
B. Hypotension is a classic sign of shock, but it generally occurs after compensatory mechanisms have failed. It is not the earliest indicator.
C. A decreased level of consciousness occurs later in the progression of shock due to decreased cerebral perfusion. It is not the earliest sign of shock.
D. Increased respiratory rate is often the earliest indicator of shock. As the body attempts to compensate for decreased oxygen delivery and tissue perfusion, the respiratory rate increases to enhance oxygenation and eliminate excess carbon dioxide. This compensatory mechanism is typically one of the first signs that shock is developing.

A. Increase fluid intake. B. Decrease protein intake. C. Decrease carbohydrate intake. D. Limit intake of potassium-rich foods.

Correct Answer is C

Explanation

B. Decreasing protein intake is not recommended because muscle wasting is a concern in Cushing disease, and adequate protein is necessary to maintain muscle mass.
C. Decreasing carbohydrate intake is recommended because Cushing disease can cause hyperglycemia, and reducing carbohydrates can help manage blood glucose levels.
D. Limiting potassium-rich foods is not advisable as Cushing disease can lead to hypokalemia, and clients may need to increase their potassium intake.
