​a client with hypovolemia has been prescribed intravenous fluid at 125ml/hr. the iv site to provide hydration has infiltrated.
Levart [38]

The following are the steps the nurse would take to treat the infiltrated site:  

1. Stop the infusion and remove the catheter

2. Elevate the extremity

3. Encourage an active range of motion

4. Apply a cold or warm compress depending on the solution infusing

5. Restart the infusion proximal to the location or in another extremity

Now, in order to address hydration requirements of the client, the nurse will have to begin a novel peripheral intravenous in another extremity or to again start the infusion if intravenous access has been created.

Why is it wrong to say that bread is a compound?
tatiyna

Explanation:

Bread cannot be classified as a compound. Compounds are formed when two or more substances are bonded together chemically, however, mixtures are not chemically bonded.

Bread is a mixture of several compounds such as sugars, proteins, lipids and gases along with a culture of organisms or chemical leavEning agaent. Several of these components

Explanation:

Large chains of monomers form biological macromolecules which carry out many essential functions in the body these can include nucleic acids, carbohydrates, proteins and lipids. These are organic molecules, meaning they're ringed or long-chain Carbons bonded to the elements oxygen (O), hydrogen (H), nitrogen (N) and phosphorus (P).

  • Proteins are structural support molecules comprised of long chains of amino acids joined via peptide (CONH) bonds; these are 20 specific units that are arranged into several macromolecules. Amino acids are absorbed through digestion and are incorporated into the body’s cells to make up organs muscles signal molecules and an alternative energy source.                                                                 Basic makeup: C, H, O, N, S; polar C, O double bonds and N-H bonding
  • Carbohydrates function to supply energy and support molecules they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. They include monosaccharides, disaccharides and polysaccharides which describes the type of bonding and the degree of complexity of the polymers.                Basic makeup: C, H, O -with many polar OH groups
  • Lipids function as energy storage and chemical messengers, these include fats, saturated and unsaturated fatty acids with double bonds and steroids and waxes. However, lipids are comprised of fatty acids and glycerol; they do not contain a fixed set of monomers, and unlike the other biological macromolecules, they are not polymers. The arrangement of hydrophobic heads and hydrophobic fatty acid tails can give these non-polar macromolecules hydrophilic and hydrophobic properties.                                                                     Basic makeup: C, H, O; non polar- a triple condensation reaction produces the molecules from a triple hydroxyl (OH) alcohol bonded to three long-chain carboxylic acids.
