First Generation Cephalosporins
cephalosporin agents with excellent coverage against gram-positive cocci, such as staphylococcus and streptococcus. they have some activity against the gram-negative bacteria, but in general, gram-negative activity is decreased compared to 2nd, 3rd, and 4th generation cephalosporins.
Second Generation Cephalosporins
agents with less activity against gram-positive cocci than first generation cephalosporins but have increased activity against gram-negative bacilli.
Third Generation Cephalosporins
agents that are structurally similar to other cephalosporins but have a broader spectrum of activity against bacteria than the first and second generation cephalosporins. these agents cover more resistant streptococcus, staphylococcus, gram-positive anaerobes, and more resistant strains of haemophilus, neisseria, proteus, escherichia coli, and klebsiella (hnpek).
Cephalothin
a cephalosporin antibiotic.
Cephradine
a semi-synthetic cephalosporin antibiotic.
Clavulanic Acid
a beta-lactam antibiotic produced by the actinobacterium streptomyces clavuligerus. it is a suicide inhibitor of bacterial beta-lactamase enzymes. administered alone, it has only weak antibacterial activity against most organisms, but given in combination with other beta-lactam antibiotics it prevents antibiotic inactivation by microbial lactamase.
Clavulanic Acids
acids, salts, and derivatives of clavulanic acid (c8h9o5n). they consist of those beta-lactam compounds that differ from penicillin in having the sulfur of the thiazolidine ring replaced by an oxygen. they have limited antibacterial action, but block bacterial beta-lactamase irreversibly, so that similar antibiotics are not broken down by the bacterial enzymes and therefore can exert their antibacterial effects.
When coding a poisoning or reaction to the improper use of a medication (e.g., overdose, wrong substance given or taken in error, wrong route of administration), first assign the appropriate code from categories T36-T50. The poisoning codes have an associated intent as their 5th or 6th character (accidental, intentional self-harm, assault and undetermined. If the intent of the poisoning is unknown or unspecified, code the intent as accidental intent. The undetermined intent is only for use if the documentation in the record specifies that the intent cannot be determined. Use additional code(s) for all manifestations of poisonings.
The appropriate 7th character is to be added to each code from block Poisoning by, adverse effect of and underdosing of systemic antibiotics (T36). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
The code is referenced in the Table of Drugs and Chemicals, this table contains a classification of drugs, industrial solvents, corrosive gases, noxious plants, pesticides, and other toxic agents.
According to ICD-10-CM coding guidelines it is advised to do not code directly from the Table of Drugs and Chemicals, instead always refer back to the Tabular List when doing the initial coding. Each substance in the table is assigned a code according to the poisoning classification and external causes of adverse effects. It is important to use as many codes as necessary to specify all reported drugs, medicinal or chemical substances. If the same diagnosis code describes the causative agent for more than one adverse reaction, poisoning, toxic effect or underdosing, utilize the code only once.

Antibiotics
What are antibiotics?
Antibiotics are medicines that fight bacterial infections in people and animals. They work by killing the bacteria or by making it hard for the bacteria to grow and multiply.
Antibiotics can be taken in different ways:
- Orally (by mouth). This could be pills, capsules, or liquids.
- Topically. This might be a cream, spray, or ointment that you put on your skin. It could also be eye ointment, eye drops, or ear drops.
- Through an injection or intravenously (IV). This is usually for more serious infections.
What do antibiotics treat?
Antibiotics only treat certain bacterial infections, such as strep throat, urinary tract infections, and E. coli.
You may not need to take antibiotics for some bacterial infections. For example, you might not need them for many sinus infections or some ear infections. Taking antibiotics when they're not needed won't help you, and they can have side effects. Your health care provider can decide the best treatment for you when you're sick. Don't ask your provider to prescribe an antibiotic for you.
Do antibiotics treat viral infections?
Antibiotics do not work on viral infections. For example, you shouldn't take antibiotics for:
- Colds and runny noses, even if the mucus is thick, yellow, or green
- Most sore throats (except strep throat)
- Flu
- Most cases of bronchitis
What are the side effects of antibiotics?
The side effects of antibiotics range from minor to very severe. Some of the common side effects include:
- Rash
- Nausea
- Diarrhea
- Yeast infections
More serious side effects can include:
- C. diff infections, which cause diarrhea that can lead to severe colon damage and sometimes even death
- Severe and life-threatening allergic reactions
- Antibiotic resistance infections
Call your health care provider if you develop any side effects while taking your antibiotic.
Why is it important to take antibiotics only when they're needed?
You should only take antibiotics when they are needed because they can cause side effects and can contribute to antibiotic resistance. Antibiotic resistance happens when the bacteria change and become able to resist the effects of an antibiotic. This means that the bacteria continue to grow.
How do I use antibiotics correctly?
When you take antibiotics, it is important that you take them responsibly:
- Always follow the directions carefully. Finish your medicine even if you feel better. If you stop taking them too soon, some bacteria may survive and re-infect you.
- Don't save your antibiotics for later.
- Don't share your antibiotic with others.
- Don't take antibiotics prescribed for someone else. This may delay the best treatment for you, make you even sicker, or cause side effects.
Centers for Disease Control and Prevention
Poisoning
A poison is any substance that is harmful to your body. You might swallow it, inhale it, inject it, or absorb it through your skin. Any substance can be poisonous if too much is taken. Poisons can include:
- Prescription or over-the-counter medicines taken in doses that are too high
- Overdoses of illegal drugs
- Carbon monoxide from gas appliances
- Household products, such as laundry powder or furniture polish
- Pesticides
- Indoor or outdoor plants
- Metals such as lead and mercury
The effects of poisoning range from short-term illness to brain damage, coma, and death. To prevent poisoning it is important to use and store products exactly as their labels say. Keep dangerous products where children can't get to them. Treatment for poisoning depends on the type of poison. If you suspect someone has been poisoned, call your local poison control center at 1-800-222-1222 right away.
Self-Harm
What is self-harm?
Self-harm, or self-injury, is when a person hurts his or her own body on purpose. The injuries may be minor, but sometimes they can be severe. They may leave permanent scars or cause serious health problems. Some examples are:
- Cutting yourself (such as using a razor blade, knife, or other sharp object to cut your skin)
- Punching yourself or punching things (like a wall)
- Burning yourself with cigarettes, matches, or candles
- Pulling out your hair
- Poking objects through body openings
- Breaking your bones or bruising yourself
Self-harm is not a mental disorder. It is a behavior - an unhealthy way to cope with strong feelings. However, some of the people who harm themselves do have a mental disorder.
People who harm themselves are usually not trying to attempt suicide. But they are at higher risk of attempting suicide if they do not get help.
Why do people harm themselves?
There are different reasons why people harm themselves. Often, they have trouble coping and dealing with their feelings. They harm themselves to try to:
- Make themselves feel something (because they feel empty or numb inside)
- Block upsetting memories
- Show that they need help
- Release strong feelings that overwhelm them, such as anger, loneliness, or hopelessness
- Punish themselves
- Feel a sense of control
Who is at risk for self-harm?
There are people of all ages who harm themselves, but it usually starts in the teen or early adult years. Self-harm is more common in people who:
- Were abused or went through a trauma as children
- Have mental disorders, such as
- Depression
- Eating disorders
- Post-traumatic stress disorder
- Certain personality disorders
- Misuse drugs or alcohol
- Have friends who self-harm
- Have low self-esteem
What are the signs of self-harm?
Signs that someone may be hurting themselves include:
- Having frequent cuts, bruises, or scars
- Wearing long sleeves or pants even in hot weather
- Making excuses about injuries
- Having sharp objects around for no clear reason
How can I help someone who self-harms?
If someone you know is self-harming, it is important not to be judgmental. Let that person know that you want to help. If the person is a child or teenager, ask him or her to talk to a trusted adult. If he or she won't do that, talk to a trusted adult yourself. If the person who is self-harming is an adult, suggest mental health counseling.
What the treatments are for self-harm?
There are no medicines to treat self-harming behaviors. But there are medicines to treat any mental disorders that the person may have, such as anxiety and depression. Treating the mental disorder may weaken the urge to self-harm.
Mental health counseling or therapy can also help by teaching the person:
- Problem-solving skills
- New ways to cope with strong emotions
- Better relationship skills
- Ways to strengthen self-esteem
If the problem is severe, the person may need more intensive treatment in a psychiatric hospital or a mental health day program.
