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.)
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 C
Explanation
A. Inserting a new indwelling urinary catheter could introduce new pathogens and increase the risk of infection rather than reduce it. Indwelling catheters are a known risk factor for urinary tract infections and should be avoided if possible.
B. Collecting blood cultures is an important diagnostic step, especially if sepsis is suspected. However, this action alone does not directly reduce the risk of septic shock. It is a part of the process but not the most immediate intervention.
C. Initiating intravenous (IV) antibiotics is the most critical intervention to reduce the risk of septic shock. Prompt administration of antibiotics can help control the infection before it progresses to sepsis, making this the priority action.
D. Obtaining placement of an intravenous access for fluid administration is necessary for managing sepsis or septic shock, but the first step should be administering antibiotics to treat the infection causing the sepsis. Fluid administration supports blood pressure and circulation but does not directly address the underlying infection.
Correct Answer is A
Explanation
A. The first priority in this situation is to open the client's airway using the jaw-thrust maneuver. This technique is preferred for clients with suspected spinal injuries to avoid further spinal cord damage. Ensuring the airway is open and providing oxygenation are immediate life-saving actions.
B. Checking cranial nerve function, including assessing pupils, is important for evaluating neurological status but is not the first action when the client is not breathing. Ensuring the airway is open and providing oxygenation is the priority.
C. While placing the client in a rigid cervical collar is important for stabilizing the spine and preventing further injury, it should be done after ensuring the airway is clear. The immediate concern is to address the client's non-breathing status.
D. Evaluating the client for brain injury is important for overall assessment but is secondary to addressing the immediate life threat of not breathing. Ensuring the airway is open and then stabilizing the spine is the priority.
