A 6-year-old child ate a peanut butter sandwich at snack time in school. Five minutes later, her
throat became swollen and she collapsed. This
allergic reaction occurred because her body
(1) recognized an antigen in peanut butter and
produced antibiotics against it
(2) digested the white blood cells that can
recognize an antigen in peanut butter
(3) did not recognize an antigen in peanut
butter and could not produce antibodies
against it
(4) recognized an antigen in peanut butter and
produced an immune response

Answers

(4) recognized an antigen in peanut butter and produced an immune response.
Allergies occur when the body recognizes an antigen called allergen and reacts abnormally to it by producing immune responses which are usually inflammatory. This response is considered abnormal because the allergens are in other respects harmless to the body.
The answer is 3. did not recognize an antigen in peanut butter and could not produce antibiotics against it.

A client who uses portable home oxygen states, "i still like to smoke cigarettes every now and then." what is the appropriate nursing response?

Answers

Correct answer: you should never smoke when oxygen is in use.

Explanation: Although oxygen is a gas which doesn't catch fire. But an environment rich in oxygen can easily cause burning of other substances which catch fire quickly. Therefore, doctors suggest that the patient should put off the oxygen mask away for few minutes while he/she is smoking.

Also, since the patients on oxygen already have some sort of respiratory or heart diseases, such patients can worsen the condition by smoking.

"you should not smoke when O2 is in use."

What does natural resource management aim at? Natural resource management aims at _________ management of resources.

Answers

Answer:

The correct answer is : Sustainable

Explanation:

  • Natural resources available on earth are the only source of energy to all living beings.
  • They are of two types, Renewable and Non-renewable.
  • Renewable resources are those that are present in ample amount and can regenerate themselves very quickly and hence do not get exhausted. Eg: Sun, Wind, etc.
  • Non-Renewable resources are those that require a lot of time for their formation and if utilised at a rate which is much higher than its formation rate, can result in its exhaustion. Eg: Fossil fuels, Fresh water from glaciers.
  • Natural Resources need to be utilised economically or in a sustained manner  by the present generation to give the nature ample time to regenerate them and to ensure that some resources are retained for the future generations.

Bears typically eat a mixture of plants and animal food sources. When a bear is unable to find meat, it will have a much lower fat intake, which will limit its supply of (1)___. This would directly affect the (2)___ and normal body functions. 1. amino acids, essential fatty acids, or glucose.
2. cell membrane, muscles, or bones.

Answers

Ans.

Fats are complex biomolecules, made up of long hydrocarbon chains. For bears, meat and fishes are main source of fats. Fats provide essential fatty acids to the body that play various biological roles, such as in energy storage functioning of bones, and insulating vital organs.

When a bear cannot find meat, it will show a much lower intake of fats. Lower fat intake would lead to limit the supply of essential fatty acids as these molecules are produced by the digestion of fats.

Essential fatty acids molecules help in proper growth and functioning of bones, as they are necessary for proper calcium metabolism. So, limited supply of essential fatty acids will directly affect the bones and normal body functions.

Thus, the correct options are 1). essential fatty acids and 2). bones.
