1. Which organ is responsible for filtering blood and removing waste products?

• A. Liver
• B. Kidneys
• C. Spleen
• D. Pancreas

Correct answer: B

Rationale: The correct answer is B: Kidneys. The kidneys are responsible for filtering blood and removing waste products from the body through the production of urine. The liver plays a role in detoxifying the blood and producing bile, while the spleen is involved in filtering blood and removing old or damaged red blood cells. The pancreas is primarily responsible for producing digestive enzymes and regulating blood sugar levels. Therefore, the kidneys are the specific organ dedicated to the filtration of blood and removal of waste products, making them the correct choice in this question.

2. She checks the documentary requirements for the applicants for staff nurse position. Which

• A. Certificate of previous employment
• B. Record of related learning experience (RLE)
• C. Membership to accredited professional organization
• D. Professional identification card

Correct answer: C

Rationale: The correct answer is C: 'Membership to accredited professional organization.' When hiring staff nurses, verifying their membership to an accredited professional organization is crucial as it ensures that the applicant is recognized and affiliated with a reputable body in the nursing field. This membership signifies adherence to professional standards and ongoing education and development. While the other options are important in assessing a candidate's qualifications, membership to an accredited professional organization directly relates to the professional standing and commitment to the nursing profession, making it a key documentary requirement for the staff nurse position.

3. Which group of elements are known for their vibrant colors and use in fireworks?

• A. Noble gases
• B. Alkali metals
• C. Halogens
• D. Transition metals

Correct answer: D

Rationale: Transition metals exhibit diverse electronic configurations, leading to their ability to emit specific colors of light, making them ideal for fireworks.

4. What is the term for the first exposure to a specific pathogen, leading to the development of an initial immune response?

• A. Primary immune response
• B. Secondary immune response
• C. Hypersensitivity reaction
• D. Immunological tolerance

Correct answer: A

Rationale: The correct answer is A: 'Primary immune response.' The primary immune response refers to the initial encounter with a specific pathogen, which triggers the immune system to respond by producing antibodies and memory cells. This process lays the foundation for the secondary immune response, which occurs upon subsequent exposure to the same pathogen. The primary immune response is characterized by the lag time in antibody production as the immune system is mobilized to combat the new threat. In contrast, the secondary immune response is faster and more robust due to the presence of memory cells from the primary response. Hypersensitivity reactions involve an exaggerated immune response to an antigen, while immunological tolerance refers to the immune system's ability to recognize self from non-self to prevent autoimmunity.

5. Which sexually transmitted infection (STI) can potentially cause infertility in both men and women if left untreated?

• A. Human papillomavirus (HPV)
• B. Chlamydia
• C. Gonorrhea
• D. Syphilis

Correct answer: D

Rationale: The correct answer is D: Syphilis. Syphilis is a sexually transmitted infection that can potentially cause infertility in both men and women if left untreated. In men, untreated syphilis can lead to damage to the testicles and epididymis, affecting sperm production. In women, syphilis can result in pelvic inflammatory disease (PID) which can lead to scarring and blockages in the fallopian tubes, causing infertility. While other STIs like chlamydia and gonorrhea can also lead to infertility if left untreated, syphilis is particularly known for its severe impact on reproductive health in both genders.

6. Which of the following functional groups is present in carboxylic acids?

• A. Carbonyl
• B. Hydroxyl
• C. Carboxyl

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group (-COOH). The other choices are associated with different functional groups.
