A nurse who is working in the poison control center receives a telephone call from a parent

1 answer:

3 0

The nurse should advice the parent on how they can quickly administer first aid because the distance between the home of the child and the hospital might be far and anything can happen before the child gets to the hospital for proper medical attention. Firstly, the parent should make sure that the item that might have lead to the poisoning far from the child and encourage the child to spit it out or have such items removed by using finger. The parent need to show the item to the doctors when she gets to the hospital so that the right diagnosis can be sort for immediately. The parent should however not force the child to vomit as this might lead to complications . If the child is not breathing the parent should patiently wait for emergency help from 911 to arrive

if placed in tap water, an animal cell will undergo lysis, whereas a plant cell will not. what accounts for this difference?

malfutka [58]

When placed in tap water, which is a hypotonic environment, animal cells have a higher solute concentration inside of the cell compared to the tap water. ... This, however, is not the case for plant cells which has a strategy to prevent lysis when put in a hypotonic environment. So the answer to your question is D

A) Compare and contrast diffusion, passive transport (diffusion & facilitated), primary active transport and secondary activ

zheka24 [161]

Answer:

Passive transport: It does not need any energy to occur. Happens in favor of an electrochemical gradient. Simple diffusion and facilitated diffusion are kinds of passive transport.

Simple diffusion: molecules freely moves through the membrane.

Facilitated diffusion: molecules are carried through the membrane by channel proteins or carrier proteins.

Active transport needs energy, which can be taken from the ATP molecule (Primary active transport) or from a membrane electrical potential (Secondary active transport).

Explanation:

Diffusion: This is a pathway for some small polar hydrophilic molecules that can freely move through the membrane. Membrane´s permeability depends on the size of the molecule, the bigger the molecule is, the less capacity to cross the membrane it has. Diffusion is a very slow process and to be efficient requires short distances and pronounced concentration gradients. An example of diffusion is osmosis where water is the transported molecule.

Facilitated diffusion: Refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this passive transport. If uncharged molecules need to be carried this process depends on concentration gradients and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.

Simple diffusion and facilitated diffusion are passive transport processes because the cell does not need any energy to make it happen.

Active transport occurs against the electrochemical gradient, so it does need energy to happen. Molecules go from a high concentration side to a lower concentration side. This process is always in charge of carrier proteins. In primary active transport the energy needed comes from the ATP molecule. An example of primary active transport is the Na-K bomb. In secondary active transport, the energy comes from the membrane electric potential. Examples of secondary active transport are the carriage of Na, K, Mg metallic ions.

In a swamp a bird and a turtle feed on the same kind of fish. This will most likely result in Competition is an relations between organisms or species in which both need a resource that is in limited pool.

<h3>What is competition in an ecosystem?</h3>

Competition will happen between organisms in an ecosystem when their niches overlay , they both try to utilize the exact resource and the resource is in lack of supply.

Fuana contend for chow, water and area to live. flora contend for light, water, minerals and root area.

So,Competition is an relations between organisms or species in which both need a resource that is in limited pool.

A 58 year old lawyer presents in the emergency room with headache, irritability, generalized muscle pain and uncontrollable back

Lerok [7]

Answer:

A. What is your diagnosis here?

As per symptoms and incident of puncturing left arm with nail from an old barn indicates it can be infection of Clostridium tetani causing disease tetanus.

When such kinds of wound occurs, there should be injection of tetanus immunoglobulin (TIG) immediately. This injection contains antibodies against Clostridium tetani which can kill the microorganism. It should be injected as soon as possible. But this is short term immediate medication.

B. What is the proper treatment of this problem?

For the treatment antibiotic penicillin, metronidazole or tetracycline can be given, it prevents multiplication of bacteria and production of neurotoxin from bacteria. these neurotoxins are responsible for muscular spasms. Along with antibiotic some anticonvasculants, muscle relaxants can be given to reduce spasms, anxiety.

C. How could this have been prevented?

This infection can be prevented by giving its vaccine in childhood itself. Vaccine is given in the form of DTaP vaccine (diptheria, tetanus toxoid, acellular pertusis). It is given in 5 shots. It is given in the arm or thigh when child is at 2 month age, 4 month age, 6 month age, 15 to 18 month age, 4- 6 years of age.
