A nurse is shown an image of the Cervavac vaccine vial. The nurse correctly identifies that this vaccine is administered to prevent which type of cancer?

1. A

   Liver Cancer

2. B

   Breast Cancer

3. C

   Lung Cancer

4. D

   Cervical Cancer

Appeared in: NORCET 9 Prelims-2025

Explanation

• The image and its text identify the vaccine as Cervavac, a quadrivalent vaccine for Human Papillomavirus (HPV).
• Persistent infection with high-risk HPV types is the primary cause of cervical cancer.
• This vaccine specifically includes HPV types 16 and 18, the two strains responsible for about 70% of all cervical cancers, making it a prophylactic (preventive) measure against this disease.

Why Other Options Were Wrong

• Option A: The HPV vaccine does not protect against liver cancer. The primary causes of liver cancer are chronic hepatitis B or C infection and liver cirrhosis.
• Option B: There is currently no vaccine available to prevent breast cancer. Prevention strategies focus on lifestyle modifications, regular self-examinations, and mammography screening.
• Option C: There is no vaccine to prevent lung cancer. The most significant risk factor is tobacco smoking, and prevention is centered on smoking cessation and avoiding secondhand smoke.

Related Visual

• Visual 1: Diagram - An illustration showing the progression from HPV infection of the cervical cells to the development of cervical cancer over several years. This helps visualize the importance of early prevention through vaccination.
• Visual 2: Infographic - A chart showing the recommended HPV vaccination schedule for adolescents in India, including the number of doses and age groups, to reinforce the practical application of this knowledge for a nurse.

Clinical Relevance

• Nursing practice connection: Use the key finding related to HPV Vaccination and Cancer Prevention to guide bedside assessment, documentation, and the next nursing action.
• Nurses play a pivotal role in advocating for and administering the HPV vaccine. This includes educating parents and adolescents about its safety, efficacy, and importance in preventing cancer, thereby increasing vaccination uptake.
• In the Indian context, where cervical cancer is the second most common cancer in women, promoting HPV vaccination is a critical public health intervention that nurses are at the forefront of.
• What if? If a 30-year-old woman who was never vaccinated asks for the vaccine, the nurse should advise her to consult a doctor. While the vaccine is most effective before sexual debut, 'catch-up' vaccination is recommended for some up to age 26. For adults aged 27-45, it involves a shared clinical decision-making process with their provider, as the benefits may be limited.

How to Approach the Question

• Step 1: Carefully examine the image and any accompanying text. Identify the key information on the packaging: the name 'CERVAVAC' and the description 'Quadrivalent Human Papilloma Virus... Vaccine'.
• Step 2: Recognize that 'Human Papillomavirus' is abbreviated as HPV.
• Step 3: Access your knowledge base to recall the primary disease prevented by the HPV vaccine. The strongest and most well-known link is with cervical cancer.
• Step 4: Evaluate the given options based on this connection. Cervical Cancer is directly associated with HPV infection.
• Step 5: Eliminate the other options by recalling their primary causes or prevention methods (e.g., Hepatitis B vaccine for liver cancer, smoking cessation for lung cancer), confirming that the HPV vaccine is the correct answer for preventing cervical cancer.

Concept Tested & Keywords

• Concept Tested: HPV Vaccination and Cancer Prevention
• Stem keywords: Cervavac vaccine, prevent, cancer
• Lead-in keywords: which type
• Clinical cues: The image of the vaccine vial and box is the primary cue, identifying the product as 'Cervavac' and a 'Quadrivalent Human Papilloma Virus' vaccine.
