The nurse is caring for a patient who is receiving vancomycin (Vancocin). The nurse notes that the patient is experiencing flushing, rash, pruritus, and urticaria. The patient’s heart rate is 120 beats per minute, and the blood pressure is 92/57 mm Hg. The nurse understands that these findings are consistent with:
A.
allergic reaction.
B.
rhabdomyolysis.
C.
Stevens-Johnson syndrome.
D.
red man syndrome.
The correct answer and Explanation is :
The correct answer is:
D. Red man syndrome.
Explanation:
Red man syndrome is a common reaction associated with the rapid infusion of vancomycin, an antibiotic used to treat serious infections caused by Gram-positive bacteria. This syndrome is characterized by a combination of symptoms including flushing, rash, pruritus (itching), urticaria (hives), and in some cases, hypotension (low blood pressure). The flushing and rash often start on the upper body and may spread to the face and neck, which is why it is sometimes referred to as “red man syndrome.”
The reaction typically occurs because vancomycin, when administered too quickly, can cause the release of histamine from mast cells in the body. Histamine is a chemical involved in local immune responses, including inflammation and allergic reactions. The rapid infusion of vancomycin can cause an exaggerated histamine release, leading to the symptoms described.
The patient’s symptoms of flushing, rash, pruritus, urticaria, tachycardia (heart rate of 120 beats per minute), and hypotension (blood pressure of 92/57 mm Hg) are consistent with red man syndrome rather than other conditions. For example:
- Allergic reactions: While allergic reactions can cause similar symptoms, they are usually more severe and may involve anaphylaxis, which is a life-threatening emergency with different symptoms and typically requires immediate treatment.
- Rhabdomyolysis: This condition involves muscle breakdown and is not associated with flushing or rash. It usually presents with muscle pain, weakness, and elevated levels of muscle enzymes in the blood.
- Stevens-Johnson syndrome: This is a severe, life-threatening condition that presents with extensive mucosal lesions and skin detachment, which is not consistent with the symptoms described.
To manage red man syndrome, the infusion rate of vancomycin should be slowed down or temporarily halted. Administering the medication over a longer period can help minimize the risk of this reaction. Additionally, antihistamines may be used to alleviate symptoms.
