Knowledge Objective by Josecarlos Ruiz 1.- When medications are provided, they bind to receptors in the body that can either stimulate or stop an action within the body. Medications that stimulate are called agonist, while medication that block and stimuli are called antagonist. Pharmacodynamics is the process by which a medication works in the body. Intended effect is the expected reaction that the body will have in interaction with a medication. Indications are the reasons why a medication is being administered. 2.- Contraindications is when a medication will not have a positive effect in the patient, for instance activated charcoal would be contraindicative to a patient who is unconscious and cannot swallow the substance. Side effects are reactions to a medication other than the ones desired. Unintended effects are those that are not desired but are of little risk to the patient.

Parenteral medications are absorbed much more quickly for they don’t have to go through the digestive process. 5.- Per Rectum, very common in children because of easy administration and absorption reliability, and the rate of absorption is rapid. Oral or ingestion has a slow rate for the medication has to go through the digestive system. This process will take up to 1 hour. Even though this is a cheap method the reliability of absorption could be impacted by many factors. IV injections is the fastest way for a chemical to enter the blood stream, however, not every medication can be administered using this method, the rate of absorption is immediate. Intraosseous (IO) are medications that are administered directly into the blood stream through the bone marrow. It is extremely painful so most of the time is used on unconscious patients. The rate of absorption is immediate. Subcutaneous (SC) injection are administered under the skin, it is given between the skin and the
