Study Notes
Chicken Pox in Medical-Surgical Nursing
Overview
- Chicken Pox (Varicella): Highly contagious viral infection caused by the varicella-zoster virus (VZV).
- Transmission: Spread through respiratory droplets and direct contact with the rash.
Symptoms
- Incubation Period: 10-21 days after exposure.
-
Early Symptoms:
- Fever
- Fatigue
- Loss of appetite
- Headache
-
Rash Development:
- Begins as small red spots (macules) that develop into itchy vesicles (blisters).
- Progresses to crusts and scabs.
- Rash typically appears in waves over several days.
Diagnosis
- Clinical Diagnosis: Based on history of exposure and characteristic rash.
- Laboratory Tests: PCR or serology in atypical cases or for immunocompromised patients.
Complications
-
Common Complications:
- Secondary bacterial infections (impetigo).
- Pneumonia.
- Encephalitis.
-
Risk Factors for Severe Disease:
- Immunocompromised patients.
- Pregnant women.
- Newborns.
Nursing Management
-
Assessment:
- Monitor vital signs.
- Assess rash and associated symptoms.
-
Symptom Management:
- Antipruritic medications (e.g., antihistamines).
- Calamine lotion for itching.
- Acetaminophen for fever (avoid aspirin due to risk of Reye's syndrome).
-
Infection Control:
- Isolate the patient until all lesions have crusted over (typically 5-7 days after rash onset).
- Encourage good hand hygiene.
-
Patient Education:
- Importance of vaccination (Varicella vaccine).
- Signs of complications to watch for.
- Maintain hydration and rest.
Treatment
- Antiviral Medications: Acyclovir may be prescribed for severe cases or high-risk patients.
- Supportive Care: Focus on symptom relief and preventing secondary infections.
Prevention
- Vaccination: Recommended for children, healthcare workers, and individuals at high risk for severe disease.
- Post-exposure Prophylaxis: Varicella-zoster immune globulin (VZIG) may be indicated for high-risk individuals exposed to the virus.
Key Points
- Chicken pox is a preventable disease through vaccination.
- Most cases are self-limiting, but special precautions are necessary for high-risk populations.
- Nursing care should emphasize comfort, infection control, and education about the disease and its prevention.
Chicken Pox (Varicella)
- Highly contagious viral infection caused by the varicella-zoster virus (VZV).
- Transmitted via respiratory droplets and direct contact with the rash.
Symptoms
- Incubation period ranges from 10 to 21 days post-exposure.
- Early symptoms include fever, fatigue, loss of appetite, and headache.
- Rash begins as small red spots (macules) and evolves into itchy vesicles (blisters) before crusting over.
- Rash typically appears in waves, lasting several days.
Diagnosis
- Diagnosis primarily clinical, determined by exposure history and characteristic rash.
- PCR or serology tests are utilized in atypical cases or for patients who are immunocompromised.
Complications
- Common complications include secondary bacterial infections such as impetigo, pneumonia, and encephalitis.
- Severe disease risk factors include immunocompromised patients, pregnant women, and newborns.
Nursing Management
- Continuous monitoring of vital signs and assessment of the rash and symptoms are essential.
- Symptom management strategies:
- Antipruritic medications like antihistamines can alleviate itching.
- Calamine lotion is applied for topical relief.
- Acetaminophen is recommended for fever; aspirin is contraindicated due to Reye's syndrome risk.
- Infection control measures include patient isolation until lesions have crusted (usually 5-7 days post-rash onset) and promoting good hand hygiene.
- Patient education focuses on the importance of the varicella vaccine, recognizing complication signs, and maintaining hydration and rest.
Treatment
- Acyclovir, an antiviral medication, is indicated for severe cases or high-risk patients.
- Supportive care emphasizes symptom relief and prevention of secondary infections.
Prevention
- Vaccination against chicken pox is recommended for children, healthcare providers, and those at higher risk of severe disease.
- Post-exposure prophylaxis with varicella-zoster immune globulin (VZIG) is suggested for high-risk individuals exposed to the virus.
Key Points
- Chicken pox can be effectively prevented through vaccination.
- While most cases resolve without intervention, precautionary measures are critical for high-risk populations.
- Focused nursing care is vital, stressing comfort, infection control, and education on disease prevention.
