If a person had measles as a child, which of the following best describes their immunity to measles?
Naturally acquired passive immunity
Naturally acquired active immunity
Artificially acquired active immunity
Artificially acquired passive immunity
The Correct Answer is B
A. Naturally acquired passive immunity
Passive immunity occurs when antibodies are transferred (e.g., from mother to baby); it does not involve the person’s immune system actively responding.
B. Naturally acquired active immunity
This occurs when a person is exposed to a pathogen, like the measles virus, and their body mounts an immune response, producing long-lasting immunity.
C. Artificially acquired active immunity
This is obtained through vaccination, not from infection.
D. Artificially acquired passive immunity
This refers to receiving antibodies (e.g., through injection of immune globulin), not through natural infection.

Correct Answer is ["B","D"]
Explanation
A. An increase in RBCs
Increased RBCs typically indicate polycythemia or hypoxia-not infection.
B. An increase in neutrophils (WBCs)
Neutrophils increase during bacterial infections as part of the body's defense.
C. Bradycardia
Infection generally causes tachycardia, not bradycardia.
D. Localized edema
Swelling or edema at the site is a common local sign of infection.
E. An increase in platelets
Platelets may vary for many reasons, but elevated levels are not a reliable indicator of infection.
Correct Answer is B
Explanation
A. Digestive system through contaminated feces:
This is the port of exit for diseases spread by the fecal-oral route (e.g., cholera, hepatitis A).
B. Respiratory system by coughing or sneezing:
Droplet infections (e.g., flu, COVID-19, common cold) are primarily spread through respiratory secretions expelled via coughing or sneezing.
C. Central nervous system by contaminated cerebral spinal fluid:
While CSF can carry infections (e.g., meningitis), it is not a common port of exit.
D. Urinary system by contaminated urine:
Urinary tract infections may be transmitted this way, but not typically through droplets.
