DRUGS
The metric system is used exclusively when ordering and prescribing drugs. The metric unit of weight is the gram (g) and this is divided into thousandths called milligrams (mg).
The unit of volume is the liter (l) which is subdivided into thousandths called milliliters (ml). A liter is equivalent to just under two pints. The standard medicine teaspoon holds 5 ml.
Various reference books are available to help practitioners keep up to date with new drugs, the trade names of drugs, dosages and precautions with particular drugs. Manufacturers are also legally required to provide data sheets for all new drugs, giving full details of usage.
Drugs may be administered externally or internally.
Drugs are classified into groups which have a specific action, such as antibacterial drugs, which are used for the treatment of infections, or local anesthetics, which abolish pain. Some drugs belong to more than one group. For example, lignocaine, which is local and surface anesthetic. Let's take antibacterial drugs as an example.
They are administered internally to kill bacteria.
Antibiotics are drugs originally derived from microorganisms: for example, penicillin, tetracycline, and erythromycin. Many people are allergic to penicillin and
its derivatives. If such people are given any of these drugs they are liable to develop a dangerous reaction. Patients must always be asked beforehand if they are allergic to penicillin or any other drugs.
There are strict legal requirements for the purchase, storage, use, identification, dispensing and prescription of drugs.
Many drugs are poisonous if taken accidentally or in excess; others caustic and may cause painful burns. Some common sense precautions in storing drugs are to keep them well away from food and drinks; keep poisons locked up in a special poisons cabinet; and to keep caustics on the lowest shelf where accidental spillage cannot affect the eyes or burn the face.
Stocks of drugs must be stored in accordance with manufacturers' instructions and not kept beyond their expiry date. Records of their purchase, supply and expiry date must be kept for at least 11 years. Any drugs which have passed their expiry date should be discarded, together with any solutions which have become discolored or cloudy.
Should students be allowed to have their cell phones in middle school and high school? A 2010 Pew Research Center study found that 65 percent of cell-owning teens bring their phones to school despite any bans that may be in place. Most high schools now allow students to have cell phones but require them to be turned off during class because they can be disruptive and distracting.
Both high schools and families seem to have an ongoing struggle with youth cell phone use. The ramifications leave lasting effects and challenges. In a 2020 Pew Research Center article, it was shared that “a majority of parents in the United States (66%) – who include those who have at least one child under the age of 18, but who may also have an adult child or children – say that parenting is harder today than it was 20 years ago, with many in this group citing technology as a reason why.”Read on for the pros and cons of allowing cell phones in school to help make the right decision for your child.
You can be in touch with your children and know their whereabouts
The 2010 Pew study noted that 48 percent of parents use the phone to monitor their child's location. The monitoring of children’s locations during school hours should also be noted as a con for many families who don’t like the idea of tracking their high school children with technology.
Cell phones can be used in emergencies
Your kids can reach you in the event of an emergency and vice versa. Families are living through unprecedented times, regardless of whether they attend private or public schools. This generation of children has grown up with mass shootings, and specifically school shootings, being part of the news headlines that they see every year of their lives. We are now also living through a pandemic where school districts and families have heightened anxiety and true health and safety concerns on a regular basis. Knowing that you can reach loved ones in a heartbeat thanks to mobile phones during school hours can feel more important than ever in the current climate.
Cell phones can be used when help is needed
If in danger, your children can reach the authorities or a medical provider. Parents worry about everything from bullying to random violence to car accidents when their children are not only at school, but also attending activities directly after school. School students are driving from high school to work, traveling for sports meets and competitions, and visiting friends. Although parents may not love the idea of teens having their phones at school, they may want them to have access to phones for all that happens immediately following time at school.
