Tell family members to operate the PCA device for the client.
5
Teach the use of PCA after the client awakens from sedation.
The nurse should teach the client about PCA and evaluate the client's understanding by asking the client to explain it back. The client should be the one controlling the administration of the medication based on the pain. It is programmed in a way to prevent overdose. The family members should not operate the PCA device for the client because the dose depends on the pain perception by the client. The client should be taught the use of the device before the procedures so that when the client awakens from sedation, the client can administer the analgesia.</span>

<h2>Species diversity </h2>
Explanation:
In order to assess the species diversity of a community, one would need to know the number of different species present as well as the relative abundance of the different species
- Species diversity is a function of species richness, the number of species in a given locality and species evenness, the degree to which the relative abundances of species are similar
- The composition of species in a given ecosystem is the result of long lasting evolution
- Each species has adapted to its own niche, which is characterized by certain features (e.g. temperature range, availability of food or light) enabling the species to reproduce and thus maintain its population
- The loss of one species affects many other species and causes imbalance
- As a result, several functions within and of the system are not carried out any more
- Any species that will take over the lost specie's niche will most certainly not replace all of the functions it used to perform
