In collecting a dermal puncture specimen into a microcollection container, tapping the container on a hard surface is recommended as it will allow the blood to mix with the anticoagulant, if present.

What is dermal puncture?

  • A dermal (skin) puncture may be required when a venipuncture cannot be performed or may be the option of choice for some point-of-care test procedures.
  • The puncture is quick and standardized for puncture depth.
  • The procedure takes longer to complete. This delay in collection of the blood specimen could result in hemolysis or clotting of the blood or tissue fluid contamination of the specimen and specimen rejection by the laboratory.
  • The dermal puncture minimizes the amount of blood taken from the patient. This will be important to consider, especially with infants in an intensive care nursery.
  • Some laboratory tests require larger amounts of blood for testing; in these cases, capillary collection is not an option.
  • If a patient is dehydrated or has poor peripheral circulation, an adequate blood collection from a dermal puncture may not be possible.
  • When a dermal puncture is performed it should be noted on the requisition. The concentration of glucose may be higher in blood obtained by dermal puncture, and the concentrations of sodium, total protein, and calcium may be lower.

_The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of
Hoochie [10]

Complete question:

The endplate potential (EPP) at the frog neuromuscular junction occurs because ACh simultaneously increases the conductance of the postsynaptic membrane to Na and K

  • True
  • False

Answer:

TRUE

Explanation:

The Acetylcholine neurotransmitter is released from the presynaptic cell by the process of exocytosis.

Once the molecule is in the intercellular space, it moves forward the postsynaptic membrane to join its receptor in the motor plate.

Once the joining has occurred, the receptor acquires a channel shape allowing the ion transference that will make possible the modification of the action potential. Ions traffic will consist of the pass of sodium and calcium to the interior of the cell and potassium to the exterior. Quantitatively, the interchange Na-K is the most significant.

K+ follows a concentration gradient, while Na+ follows an electrochemical gradient. The interchange results in an increase of positive charges in the interior of the muscular cell.

Whenever there is a sufficient number of Acetylcholine receptors are active, the depolarization threshold of the motor endplate is exceeded. This activates an action potential that extends to the rest of the muscle membrane.

What is the difference between fusion and fission reactions? select 2 that apply
Mumz [18]

Answer:

Difference between fusion reaction and fission reaction.

Explanation:

Fission reaction produce energy while fusion reaction absorb energy.This happens because fission reaction deals with the breakdown of one larger nucleus which result in the generation or liberation of energy.Whereas Fusion reaction combines two smaller atomic nuclei,as a result of which it requires energy for the joining of two smaller atomic nuclei into a larger nucleus.

How do earthworms enrich plant growth?
Luba_88 [7]

Answer:

They tunnel through the soil, which allows air to enter.

Explanation:

Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.

They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.

Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.
