The nurse is about to administer 1 liter (1000 mL) of 0.9% NS over 2 hours intravenously to a patient in shock.
What rate should the nurse set on the infusion pump?
The Correct Answer is ["167"]
To calculate the rate for the infusion pump, you would divide the total volume by the total time, then multiply by the drop factor. Here’s how you can do it: Step 1 is: Calculate the total volume in mL, which is 1000 mL.
Step 2 is: Calculate the total time in minutes. Since there are 60 minutes in an hour, 2 hours is 120 minutes.
Step 3 is: Divide the total volume by the total time. So, 1000 mL ÷ 120 min = 8.33 mL/min.
Step 4 is: Multiply the result by the drop factor. If we assume a standard drop factor of 20 drops/mL, then (8.33 mL/min) × 20 drops/mL = 166.67 drops/min. So, the nurse should set the infusion pump to approximately 167 drops per minute. Vital signsVital signs Explore

Correct Answer is A
Explanation
Choice A rationale
During the fluid resuscitation phase of burn management, the primary goal is to restore circulating volume and preserve vital organ and tissue perfusion. One of the most effective methods for assessing the results of fluid resuscitation is monitoring urine output. A urine output greater than 0.5 mL/kg/hr is generally considered an indicator of adequate fluid resuscitation.
Choice B rationale
While clear bilateral breath sounds are an important part of overall patient assessment, they are not the best method for assessing the results of fluid resuscitation in burn management.
Choice C rationale
Serum hemoglobin is not the best indicator for assessing the results of fluid resuscitation in burn management. While it can provide information about the patient’s overall health and blood volume, it does not directly reflect the adequacy of fluid resuscitation.
Choice D rationale
A heart rate of 122/min could indicate a response to pain, anxiety, or inadequate fluid resuscitation. However, it is not the best method for assessing the results of fluid resuscitation in burn management.
Correct Answer is D
Explanation
Choice A rationale
While fatigue is a common symptom of Hodgkin’s disease, it is not the most urgent symptom to address when there is significant cervical lymph node enlargement.
Choice B rationale
Pain can be a symptom of Hodgkin’s disease, but it is not the most urgent symptom to address in this case.
Choice C rationale
Fever can be a symptom of Hodgkin’s disease, but it is not the most urgent symptom to address in this case.
Choice D rationale
Stridor is a high-pitched, wheezing sound caused by disrupted airflow. Stridor may indicate a serious condition affecting the throat or larynx (voice box). With significant cervical lymph node enlargement, the lymph nodes may be pressing on the airway, causing stridor. This is a medical emergency and should be addressed first.
