Chicken Pox in Medical-Surgical Nursing

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.
