A 57-year-old male patient in DIC is to receive 1 unit of packed red blood cells over 2 hours. There is 250 mL in the infusion bag. 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.

When the low-pressure alarm sounds, it indicates that the pressure being detected by the arterial line is below the set threshold. This could be due to a variety of reasons, such as a loose connection, air bubbles, or a shift in the zero-reference point.
Rezeroing the monitoring equipment involves recalibrating or resetting the baseline reference point for the arterial pressure waveform. This ensures accurate measurement and monitoring of the patient's arterial pressure.
A. Checking the right hand for a rash in (option A) is incorrect because While assessing the patient for any skin changes or rashes is important, it is not the first action to take in response to a low-pressure alarm.
B. Assessing the waveform for under-dampening in (option B) is incorrect because Assessing the waveform characteristics is important in arterial line monitoring, but it may not be the initial action when the low-pressure alarm sounds. Rezeroing the equipment should be performed before assessing waveform characteristics.
C. Assessing for cardiac dysrhythmias in (option C) is incorrect because Assessing for dysrhythmias is an important aspect of patient care, but it may not be directly related to the low-pressure alarm from the arterial line. Rezeroing the monitoring equipment takes precedence.
Therefore, when the low-pressure alarm sounds for a patient with an arterial line, the nurse should first re-zero the monitoring equipment to ensure accurate measurement of arterial pressure.

Cool, clammy skin, tachycardia, and hypotension are signs of shock, indicating inadequate tissue perfusion and oxygenation. The immediate priority is to ensure adequate oxygen delivery to the tissues. Providing oxygen at 100% via a non-rebreather mask helps increase the patient's oxygen saturation and improve tissue oxygenation.
While all the options mentioned are important in the management of a patient in shock, oxygenation takes priority as it directly addresses compromised tissue perfusion and oxygenation.
A. Inserting two large-bore IV catheters in (option A) is incorrect because: Establishing intravenous access is crucial for fluid resuscitation and administration of medications, but it can be done after ensuring adequate oxygenation.
C. Drawing blood to type and crossmatch for transfusions in (option C) is incorrect because Blood typing and crossmatching are important for potential blood transfusions but should not be the first action in this critical situation.
D. Initiating continuous electrocardiogram (ECG) monitoring in (option D) is incorrect because Continuous ECG monitoring is important for assessing cardiac rhythm and detecting any dysrhythmias, but ensuring oxygenation should be the initial priority.
Therefore, in a patient presenting with cool, clammy skin, tachycardia, and hypotension, the nurse should first provide oxygen at 100% via a non-rebreather mask to address inadequate tissue perfusion and oxygenation.
