Question 1

Mr. Picone went to the overseas tour to Bali and there he underwent for a treatment of chest infection with oral erythromycin. However, he is allergic to cephalosporins (severe rash and fever). His chest infection did not respond as expected and it was suggested that he got pneumonia. Pharmacology is the study of processes suffering from a drug that is administered until it is removed, understood as the pharmacodynamics, pharmacokinetics, toxicology. Depending on the pharmacology study drugs with beneficial therapeutic action or study of drugs in general, we speak of Pharmacology pure when studying the interactions of drugs with the living regardless of drug action and Applied Pharmacology, when studying the drugs that return a benefit to the living.

It can be further divided according to the pharmacology of the drugs that studies regarding the action on the various body systems. This speaks of the nervous system pharmacology, pharmacology digestive system, pharmacology of the cardiovascular system, excretory system pharmacology, pharmacology of the skin.

The origin of the drugs can be vegetable (if the drug - active - comes from a plant), animal (hormones), and synthetic. Drugs of synthetic origin are a greater number compared to those of animal or vegetable origin. There is a person, named, Mr. Picone, who has chest infection. He has trouble when he takes medicine. He has problems while sleeping; therefore, he cannot take medicines on his own. He needs them to be prescribed.

Question 2

The following three strategies would be best for a nurse to adopt:

Maintain a positive attitude.

Manage their emotions in times of stress will make it possible to successfully cope with fatigue.

It would be nice to help people around the patient so that they can understand and support the patient. Family and friends can be a mentally sick person in the place and understand what it means for their fatigue (Brater 2000, 447).

Question 3

Pharmacokinetics is the branch of pharmacology that studies the processes to which a drug is put through its passage through the body. Try to figure out what happens to a drug from the time that is given to its total elimination from the body. For this, different models have been developed to simplify the many processes that take place between the organism and the drug. Although within the same model is the closest to reality, the complication involved has made ??them the single compartment model and in any case the two-compartment most commonly used. From these prisms, the detailed study of the successive steps through the drug in the body, are grouped under the anagram LADME:

Liberation of active,


Distribution by the body,

Metabolism or inactivation, to be recognized by the body as a foreign substance to it, and

Elimination of the drug or the waste that remains the same.

These different phases, involved the use and management of basic concepts to understand the momentum. Thus, the properties of the substances acting as excipients, the characteristics of biological membranes and how the substances can pass through them or the characteristics of enzymatic reactions ...
