dermatological reaction

adverse reactions involving the skin, from simple rash to potentially fatal exfoliative dermatitis. drugs are deposited in the skin and cause direct irritation to the tissue

drug allergy types

anaphylactic reactions, cytotoxic reactions, serum sickness, and delayed reactions

superinfections

antibiotics destroy normal floral leading to superinfection developing or infections caused by organisms that are usually controlled by normal flora

secondary action

antihistamines cause drying up secretions AND drowsiness, drug dose might be adjusted to remove the effects but not always

blood dyscrasia

bone marrow depression caused by drug effects on the rapidly multiplying cells of the bone marrow; lower than normal levels of blood components can be seen

adverse effects

caused for many reasons: 1. the drug may have other effects on the body besides the therapeutic effect 2. the patient may be sensitive to the drug being given 3. the drug's action on the body may cause other responses that are undesirable or unpleasant 4. the patient may be taking too much or too little of the drug, leading to adverse effects

cytotoxic reaction

complete blood count showing damage blood-forming cells; liver function tests show elevated liver enzymes; renal function decreased

toxicity

creatinine

nephrotoxicity

decrease urine output

rash intervention

drugs outweigh discomfort of skin lesion, frequent skin care, wear loose clothes, don't rub, topical corticosteroids, antihistamines, and emollients

hypersensitivity

excessive responsiveness to either the primary or the secondary effects of a drug; may be caused by a pathological condition or, in the absence of one, by a particular patient's individual response

superinfection assessment

fever, diarrhea, black/hairy tongue, inflamed and swollen tongue (glossitis), mucous membrane lesions, vaginal discharge with or without itching

drug allergy

formation of antibodies to a drug or drug protein; causes an immune response when the person is next exposed to that drug

stomatitis intervention

frequent mouth care with a nonirritating solution, frequent small meals, dental consultation, anti fungal agents/local anesthetics

anaphylactic reaction

hives, rash, difficulty breathing, panic, respiratory arrest

rash assessment

hives, rashes, lesions and exfoliative dermatitis (rash, scaling, fever, enlarged lymph nodes, enlarged liver, potentially fatal erythema multiform exudativum (stevens-johnson syndrome) which has dark red papule appearing on extremities with no pain or itching in rings or dirk patches

superinfections

infections caused by the destruction of normal flora bacteria by certain drugs, which allow other bacteria to enter and cause infection; may occur during the course of antibiotic therapy

stomatitis

inflammation of the mucous membranes related to drug effects; can lead to alteration in nutrition and dental problems

stomatitis

inflammation of the mucous membranes, can occur because of direct toxic reaction to the drug deposits in the end capillaries in the mucous membranes, leading to inflammation

serum sickness reaction

itchy rash, high fever, swollen lymph nodes, swollen/painful joints, edema

primary action

most common, from overdose, extension of desired effect, effects caused by individual response to the drug, high/low body weight, age, underlying pathology that alter the effects of the drug

poisoning

overdose of a drug that causes damage to multiple body systems and has potential for fatal reactions

delayed allergic reaction

rash, hives, swollen joints (think poison ivy)

hypersensitivity reactions

response excessively to primary or secondary effects of the drug, from pathological or underlying condition

discontinue drug

serum sickness priority is

dermatological reactions

skin reactions commonly seen as adverse effects of drugs; can range from simple rash to potentially exfoliative dermatitis

superinfection interventions

supportive measure (frequent mouth care, skin care, access to bathroom, small/frequent meals), anti fungal therapy, extreme = discontinue the drug responsible

stomatitis assessment

swollen gums, inflamed gums (gingivitis), and swollen and red tongue (glossitis), difficulty swallowing, bad breath, pain in mouth and throat

CNS

vapor = damage to baby's
