You are planning to transfuse a unit of PRBC's to your patient. You know that when you arrive at the blood bank and they hand you the unit of blood, you have how long to start the transfusion from that time?

A. A sudden new pain in a patient with SCD can be a sign of a serious complication, such as acute chest syndrome or stroke. Prompt medical evaluation is crucial to identify and address any underlying complications.
B. While an X-ray may be helpful to rule out other causes of shoulder pain, it is not the most urgent priority in this case. The patient's sudden onset of pain could be a sign of a serious complication that requires immediate attention.
C. While a head-to-toe assessment is important for any patient, it is not the most urgent priority in this case. The patient's new pain could be a sign of a serious complication that requires immediate medical attention.
D. Increasing the opioid dosage may provide temporary relief from the pain, but it does not address the underlying cause of the new pain.

A. This is not typical for Raynaud's phenomenon. Instead, Raynaud's is characterized by episodes of reduced blood flow to the extremities, often triggered by cold or stress, leading to sensations of coldness or numbness rather than warmth.
B. This finding aligns with Raynaud's phenomenon. During an episode, the blood vessels constrict in response to cold or stress, leading to pallor (whiteness) in the affected areas, such as the toes and fingers. This is a classic symptom of the condition.
C. While feet can become reddened due to increased blood flow after rewarming or after exposure to warmth, this is not a characteristic feature of Raynaud's phenomenon. In Raynaud's, the affected areas typically exhibit color changes from white (pallor) to blue (cyanosis) and then red (hyperemia) as blood flow returns, but redness upon ambulation is not specifically indicative of the phenomenon.
D. Swelling of the joints can occur in SLE due to arthritis or inflammation but is not a direct symptom of Raynaud's phenomenon. Raynaud's primarily affects blood flow and does not inherently cause joint swelling; however, a client with SLE may experience joint symptoms due to other underlying inflammatory processes.
