In fever breathing rate
A. Increase
B. Decrease
C. Stop
D. None of the above

Hint: A fever is an increase in body temperature and can be caused by many medical conditions ranging from non-serious to life-threatening. These can be bacterial, viral, and parasitic infections—such as COVID-19, the common cold, meningitis, urinary tract infections, appendicitis, influenza, and malaria. A thermometer is used to check the temperature during a fever.

Complete answer:
• Fever is also termed as pyrexia.
• It is defined as having a temperature above the normal body temperature (37.2-38.2).
• The increase in normal temperature triggers increased muscle contractions and causes a feeling of cold.
• Due to this, there is greater heat production and efforts to conserve heat.
• When the temperature gets back to normal, a person feels hot, becomes flushed, and may begin to sweat.
• It causes an increase in the heart rate, breathing rate, and blood circulation to the skin.
• This is a way for the body to reduce the heat caused by fever.

Symptoms-
• It is accompanied by sickness behavior, consisting of lethargy, depression, loss of appetite, sleepiness, and the inability to concentrate.
• Fever dreams can occur while sleeping with a fever causing intense or confusing nightmares.
• These can be of various types-
• Continuous fever, intermittent fever, remittent fever.

Hence, the correct answer is option (A).

Note: Important point to remember-
An increase in body temperature over the normal temperature, due to either too much heat production or not enough heat loss is called hypothermia. It is an example of a high-temperature phenomenon but is not a fever.
During fever, the rate of breathing and heart rate increases in order to reduce the heat caused by fever.
