27
Q

Neonates and infants have smaller skeletal structures, and this can affect the absorption of medication just as much. Since there is limited physical activity in these patients, there is a decrease in blood flow to the muscles. This causes slower absorption of the medication and increases the risk of muscle and nerve damage with any ____ injection, since the medication is not absorbed into the bloodstream as quickly as with an adult

A

IM injection

Q

The adult brain has a protective barrier called the ____, which protects it from water-soluble substances

A

blood brain barrier

31
Q

Drugs must have a certain degree of ____ or ____ solubility to penetrate this barrier and get to the brain

A

lipid- or fat-solubility

32
Q

If a lipid-soluble drug is administered to a pediatric patient, there is decreased distribution of the drug to the organs and body tissues because of the lower percentage of ____ in the body

A

fat

33
Q

The liver and the kidneys are not fully developed in pediatric patients. This causes metabolism and excretion to occur more slowly than in adults and allows the drug to stay in their body ____

A

longer

34
Q

Since a drug stays in the child’s body longer, this can lead to a build-up of the drug, causing ____

A

toxicity

35
Q

____, a preservative in bacteriostatic water for injection, which is used regularly to dilute some powder forms of IV medication, has been associated with toxicity in neonates

A

benzyl alcohol

36
Q

Cardiac output decreases significantly with age, which affects the amount of ____ that the kidneys and liver receive

A

blood

37
Q

Drug distribution is greatly affected in the aging adult because the percentage of lean body mass or muscle and the total percentage of body water are lower than in the ____

A

younger adult

38
Q

Since the amount of body fat increases with age, ____ soluble drugs are widely distributed in those organs that contain the most adipose tissue. This causes the drug to be diverted from the kidneys and liver, where the metabolism and excretion processes should take place. This slows the elimination of the drug from the body and causes it to have a longer half-life and toxicity because of the increased levels of medication in the bloodstream

A

lipid- (fat-)

39
Q

What is an Agonist effect?

A

When one medication increases the action of another

40
Q

Injectable medications have to be in an aqueous solution form to allow them to be injected into the body. They may be packaged as a solution and require preparation using a ____ to withdraw the desired amount; or, they may be packaged as a ____, which requires dilution with a specific fluid called a diluent

A

syringe

diluent

41
Q

The injectable medications will either be transferred to an ____, usually in a plastic bag, drawn up in a ____ for IV push, or be manufactured as a ____

Q

Both 5% dextrose and 0.9% sodium chloride are examples of ____ fluids

A
