- B. it increases calcium absorption from the gastrointestinal tract
- C. it acts on a cell surface receptor that increases intracellular cyclic AMP
- D. all above

Which of the following can NOT be prevented with a vaccine?
- A. tetanus
- B. pneumococcal meningitis
- C. meningococcal meningitis
- D. listeriosis
Correct Answer: D
Rationale: The correct answer is D: listeriosis. Listeriosis is caused by a bacterium and there is currently no vaccine available for it. Tetanus, pneumococcal meningitis, and meningococcal meningitis, on the other hand, are all preventable with vaccines. Tetanus is prevented by the DTaP vaccine, pneumococcal meningitis by the pneumococcal conjugate vaccine, and meningococcal meningitis by the meningococcal vaccine. Therefore, listeriosis is the only condition among the options that cannot be prevented with a vaccine.
There are ________ layers of meninges around the brain and spinal cord.
- A. one
- B. two
- C. three
- D. four
Correct Answer: C
Rationale: The brain and spinal cord are protected by three layers of meninges: the dura mater, arachnoid mater, and pia mater. These layers provide structural support, cushioning, and protection against physical injury. The dura mater is the outermost layer, the arachnoid mater is the middle layer, and the pia mater is the innermost layer. Therefore, three is the correct answer as it accurately describes the number of meningeal layers.
