The IV administration infusion set delivers 10 gtts/mL. At what flow rate (in drops per minute) should the nurse run the infusion?
Record your answer using a whole number.
Explanation
flow rate for an infusion= (Volume in mL * Drop factor) / Time in minutes.
volume of the infusion bag is 250 mL, the drop factor is 10 gtts/mL, and the time is 2 hours, which is 120 minutes.
(250 mL * 10 gtts/mL) / 120 minutes = 2500 gtts / 120 minutes ≈ 20.83 gtts/minute. Therefore, the nurse should run the infusion at a rate of approximately 21 drops per minute to deliver 1 unit of packed red blood cells over the 2-hour period.
A 30-year-old female patient is admitted to the emergency department with two systemic inflammatory response syndrome variables: temperature of 100.2°F (35°C) and high blood sugar. Which intervention from the sepsis resuscitation bundle does the nurse initiate?
A 61-year-old female patient with hypovolemic shock has these vital signs: temperature 97.9°F (36.6°C): pulse 123 beats/min: blood pressure 85/48 mamite respirations 24 breaths/min; urine output 20 mL for last 2 hours: skin cool and clammy. Which prescription order for this patient does the nurse question?
The emergency department nurse provides care for a 50-year-old male patient with septic shock. The nurse recalls that the renin- angiotensin system is activated during which stage of shock?
Which conditions can cause hypovolemic shock? Select all that apply.
A 40-year-old female patient with massive trauma and possible spinal cord injury is admitted to the emergency department (ED). The nurse suspects that the patient may be experiencing neurogenic shock in addition to hypovolemic shock, based on which one of the following?
The ICU charge nurse will evaluate that teaching about hemodynamic monitoring for a new staff nurse has been effective when the new nurse does which of the following?
A 32-year-old male patient sustains 78% TBSA burn and is currently admitted to the burn unit. Which sequential order would the nurse arrange the events involved in burn shock following a patient's exposure to burns?
Explanation
A. Decreased blood volume: Burn injuries can lead to fluid loss, primarily through damaged skin. This fluid loss causes a decrease in blood volume, leading to hypovolemia. Hypovolemia contributes to decreased cardiac output and tissue perfusion.
B. Increased vascular permeability: Burn injuries cause an inflammatory response, leading to increased vascular permeability. This increased permeability allows fluid, electrolytes, and proteins to leak from the intravascular space into the interstitial space.
C. Development of edema: The increased vascular permeability and fluid leakage lead to the development of edema. Edema occurs as fluid accumulates in the interstitial spaces, further contributing to tissue swelling and compromised perfusion.
D. Increased peripheral resistance: In response to decreased blood volume and tissue hypoperfusion, the body activates compensatory mechanisms to maintain blood pressure and tissue perfusion. One of these mechanisms is increased peripheral resistance, which occurs as blood vessels constrict to maintain blood pressure. Increased peripheral resistance helps redirect blood flow to vital organs but also contributes to increased workload on the heart.
Therefore, the correct sequential order of events involved in burn shock following a patient's exposure to burns is:
A. Decreased blood volume B. Increased vascular permeability D. Development of edema C. Increased peripheral resistance
The emergency department nurse evaluates that fluid resuscitation for a 70 kg patient in shock is effective by finding which one of the following?
