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 B
Explanation
A. Darkening the room can help reduce light sensitivity, but it does not address the underlying cause of the headache.
B. Increasing fluid intake is effective in managing a headache after a lumbar puncture because it helps replenish cerebrospinal fluid (CSF) and reduces the risk of post-lumbar puncture headache, which often results from CSF leakage.
C. Naproxen sodium can provide relief for headache pain, but increasing fluid intake addresses the root cause of the headache more directly.
D. Elevating the head of the bed is generally recommended for certain conditions, but it is not the most effective strategy for addressing a post-lumbar puncture headache, which is better managed by increasing fluid intake.
Correct Answer is A
Explanation
A. Difficulty swallowing in a client with facial burns can indicate airway compromise due to edema and should be reported immediately as it may require urgent intervention to secure the airway.
B. While pain is a significant concern and should be managed, it is not as immediately life-threatening as potential airway obstruction.
C. A respiratory rate of 24 breaths per minute is elevated but within the range of mild tachypnea, which could be due to pain or anxiety, and is not the most urgent finding.
D. Urinary output of 25 mL/hr is below normal and indicates possible hypovolemia or kidney injury, but airway concerns take precedence in this scenario.
