Introduction to Anatomy

Anatomy is the study of structure and the relationship among structures.

Introduction to Pharmacology

This Introduction to Pharmacology post features a collection of videos that provide a more visual approach for student nurses, for study purposesโ€ฆ

Pharmacology is the study of drugs and their actions on the body.

Below you can find a collection of videos that can help provide a more visual approach to an introduction to pharmacology for nursing students.


Pharmacodynamics

Pharmacodynamics refers to the mechanisms of drug action…the study of how a drug affects our bodies.

The majority of drugs elicit a response depending on how they interact with a particular protein, which happens through a receptor protein embedded in the cell membrane, or inside the cell within the cytoplasm or in the nucleus.

Sometimes a drug acts as a ligand for a receptor.

A drug may be:

  • Agonist: mimics the native ligand and elicits the typical physiological response (a.k.a. facilitator) – Agonist promotes normal function of the protein.
  • Antagonist: binds to the active site but DOES NOT activate the receptor (a.k.a. blocker / inhibitor) – Antagonist silences the protein and prevents function.

Drug Potency: the strength of a drug at a particular dosage or the amount of a drug required to produce a particular effect. Potency can also be described as the affinity of a drug for a receptor (high affinity = small amount of drug needed).

Drug Efficacy: maximum effect that can be achieved by a drug. Efficacy can also be described as the effect the drug has on the receptor and how well it acts as an agonist or an antagonist.

Pharmacokinetics

  • Absorption: how the drug moves from site of administration into the bloodstream
  • Distribution: journey through the bloodstream to reach target cells and molecules
  • Metabolism: modification by enzymes to render the drug ineffective
  • Excretion: the removal of the drug from the body via urine/faeces

COVID19 Evidence Based Preventative Measures

Back in March 2020 I conducted COVID19 Evidence Based Preventative Measures research on my own initiative to be able to provide accurate information about COVID-19 preventative measures and be of service to the public as a Nursing Student during the pandemic.

Although considered vulnerable, from day 1 during the pandemic I planned on giving back to society in the best way I can. And while I couldn’t help society through my physical presence due to being considered vulnerable, I decided to help by answering the various public questions that were arising especially in the beginning of the pandemic through spreading of evidence-based information. Being aware of the misinformation on the subject spreading like wildfire through social media, I wanted to make sure to have accurate information, especially when it comes to knowing the rationales for the preventative measures that were being shared with the public by the Maltese Health Authorities.

Hence, I thought of compiling the most recent and relevant evidence-based information into an article. At the same time I opted to use the assessment style we are required to use during our Nursing studies at the University of Malta, which included the use of APA 6th (at the time), so as to serve as practice for my future assignments during my course of study.

Although the research was carried out back in March 2020 and some things may have changed especially since studies and research are an ongoing process, certain COVID19 evidence based preventative measures are still applicable, especially during the current influx of COVID-19 incidence we are experiencing, and we should still adhere to them together as a society to curb the transmission of this virus as much as possible until a reliable vaccine is out.

Below you can find a downloadable file with the mentioned COVID19 Evidence Based Preventative Measures research article.
