Q

additive effect of medications

A
  1. When two or more medications are given at the same time and have similar actions, an additive effect will occur.
  2. Clients can take some medications together for their additive effects, so they can take lower doses of each medication.
  3. Additive effects occur when two or more medications with similar actions are taken at the same tim

16
Q

chemical stability

A

how a medication should be stored and handled to maintain maximum effectiveness

17
Q

pharmacologic action

A

the mechanism of action of a medication on the body to achieve the desired effect

18
Q

an indication of medication hypersensitivity

A

itching

19
Q

Tolerance to a medication

A

develops when it is taken over an extended period of time and the body’s response to the same dose of the medication decreases.

20
Q

medication interaction

A

occurs when a client is taking two or more medications together, and it results in an increase or decrease in therapeutic effects or causes adverse medication interactions that could result in harm to the client.

21
Q

Medication toxicity

A

-develops when the amount of a medication that is taken is greater than its rate of excretion, and it results in the medication accumulating in the body.
-A client who has renal insufficiency might have delayed or impaired excretion of the medication.
-The medication dosage should be reduced if toxicity occurs.

22
Q

Withdrawal aka (abstinence syndrome)

A

If the client is dependent on the medication, withdrawal symptoms can occur when it is abruptly discontinued. Resulting in sweating, tremors, and nausea.

23
Q

pharmacokinetics

A

section outlines how the drug is processed in the body through absorption, distribution, metabolism, and excretion

24
Q

Enteric-coated tablets

A

1.absorbed in the small intestine
2.slows the absorption of the medication
3.Dissolving an enteric-coated tablet in the mouth destroys its protective coating
4.Medications that irritate the stomach are often covered with an enteric coating that does not dissolve until the medication enters the alkaline environment of the small intestine.
5.Clients should not crush or chew enteric-coated medications because this will damage the enteric coating.

25
Q

Anaphylaxis

A

-an immediate and life-threatening allergic response, manifesting as bronchospasm, laryngeal edema, and a rapid drop in blood pressure.
-Immediate treatment with epinephrine and IV fluids is imperative.

26
Q

Agonist medications

A

bind to cell receptors in the body and are targeted to a specific type of receptor. When they attach to the receptors, they perform the same action as a hormone or chemical would, increasing the effects of that hormone or chemical. For example, pharmacological insulin is administered to clients who have little to no insulin to mimic insulin’s effects in the body.

27
Q

Antagonists

A

are medications that bind with a receptor and either block a response or precipitate a less than typical response.

28
Q

Competitive antagonists

A

medications that bind with a receptor and prevent other medications or chemicals in the body from attaching to cell receptors, which means they prevent or minimize certain effects.
