Pharmacokinetics
Definition
  • Absorption - movement of drug into the bloodstream
  • Distribution - drug transport to sites of action
  • Metabolism - chemical conversion of drug into metabolites that can be excreted
  • Excretion - elimination of drug from the body
Term

Absorption

  • Movement of drug into the bloodstream
  • Affected by:
Definition
  • Route of Administration (local vs. systemic)
  • Form (liquid, capsule, etc.)
  • Drug Solubility (water or fat soluble)
  • Blood Flow
  • Body Surface (stomach has a lot of surface area)
  • Food (food in stomach can slow absorption as long as 2 hours)
  • pH
Term

Distribution

  • Drug transport to sites of action
  • Factors affecting:
Definition
  • Cardiovascular Health
  • Local blood flow (at target area)
  • Membrane permeability
    -Blood-Brain Barrier (water soluble medications can't get into brain)
  • Protein-binding capacity (medication binds to protein albumin, only portion that is unbound is therapeutic)
Term
Metabolism
Definition
  • Biotransformation: chemical conversion of drug into metabolites that can be excreted (enzymes break down medication into metabolites, usually in liver)
  • The slower the metabolism, the greater the risk of toxicity
  • Factors affecting metabolism: liver function, other medications, health status
  • First Pass Effect - medications that are deactivated in the liver before reaching systemic circulation; must be delivered parenterally to avoid GI tract
Term
Excretion
Definition
  • Elimination of the drug
  • Primarily through kidneys (BUN & creatinine clearance indicators of kidney function, hydration helps body eliminate drugs)
  • Also through liver, lungs, bowel, sweat, mammary glands (constipation can increase medication effects)
Term
Factors Affecting Pharmacokinetics
Definition

■  Dehydration, poor nutrition, and electrolyte imbalances decrease absorption.

Term
The Elderly and Medication - Metabolism Issues

The Elderly and Medication - Excretion Issues
Definition

■  Decreased glomerular filtration rate inhibits excretion from the kidneys.
■  Diminished renal function inhibits excretion, thereby increasing the risk of toxicity.

Definition
Molecules of monounsaturated fats have one unfilled spot where hydrogen is not attached.
Term
Lipids - Polyunsaturated
Definition

Polyunsaturated fatty acids contain two or more unfilled spots for hydrogen. At the spot( s) where the molecule does not have a hydrogen attached, it becomes kinked and does not pack together. This is why these fats are liquid at room temperature.

(found in plant oils)

Term
Lipids - Saturated
Definition
Saturated fatty acids are those in which every carbon atom is fully bound to ( or “ saturated” with) hydrogen. The molecules pack tightly together at room temperature and are dense, solid, and heavy.

Animal fats are the primary source of saturated fats in the North American diet; however, many processed foods contain saturated fats.
Term
Lipids - Trans Fats
Definition
Trans- fatty acids are saturated fats created when food manufacturers add hydrogen to polyunsaturated plant oils, such as corn oil, to break the double carbon bonds and straighten out the molecules. This process solidifies the fat and extends the shelf life of the food. Trans- fats are found in many margarines and other processed foods containing hydrogenated vegetable oils.

  • Empysema: permanent enlargement of the air spaces and destruction of lung walls. Increase residual volume/decreased chest compliance and elastic recoil
Term
Dx: Congestive Heart Failure
Definition
  • Decreased Cardiac Output r/t pump failure a.e.b. HR 110 O2 Sat 88% on room air, cyanotic nail beds
  • Risk for Activity Intolerance r/t cardiac insufficiency and pulmonary congestion as evidenced by rales ausculated in bilateral lower lungs
Term
Diagnosis: Pneumonia
Definition
  • Pneumonia is an acute inflammation of the lung tissue caused by a microbial organism
  • Ineffective airway clearance r/t retained secretions and excessive mucus as evidenced by ineffective cough, adventitious breath sounds, dyspnea
Term
Anemia
Definition
  • An abnormally low level of red blood cells, hemoglobin, or both
  • Causes of anemia include blood loss, abnormal destruction of red blood cells, and deficiencies of red blood cell production (iron deficiency, vitamin B12 deficiency, folic acid deficiency, aplastic anemia, and anemias of chronic disease and chemotherapy)
Term
Signs and Symptoms of Anemia
Definition
  • Angina (chest pain)
  • Fatigue/Weakness/General Malaise
  • Restlessness/Anxiety
  • Dyspnea
  • Nail beds, skin, mucous membranes and conjunctiva become pale
  • Tachycardia
  • Cold intolerance
Term
O2 Supplementation - Nasal cannula
Definition
Flow rate/%O2: 1 L/min - 6 L/min, 24% - 44%, but % depends on how much the patient breathes in
Nursing Implications: check for skin break down (ears, nose, face), humidify to lessen dryness of nasal mucosa
Indications: when patient needs minimal O2 support
Disadvantages: does not work well if patient is a mouth breather
Term
O2 Supplementation - Simple Mask
Definition
Flow rate/%O2: 5 - 10 L/min, 40% - 60%
Nursing Implications: place face mask securely over mouth and nose
Indications: when patient has higher O2 needs than use of NC would provide
Disadvantages: uncomfortable, talking muffled, must remove to eat & drink, becomes hot
Term
O2 Supplementation - Partial Rebreathing Mask
Definition
Flow rate/%O2: 6 - 15 L/min, 50% - 90%
Nursing Implications: make sure bag does not collapse during inhalation
Indications: when patient may need to rebreathe air
Disadvantages: uncomfortable, talking muffled, must remove to eat & drink, becomes hot
Term
O2 Supplementation -Non-rebreathing mask
Definition
Flow rate/%O2: 6 - 15 L/min, 70% - 100%
Nursing Implications: make sure bag does not collapse during inhalation, be sure the mask fits snugly so the patient will not breathe room air
Indications: when patient needs extremely high concentrations of O2
Disadvantages: uncomfortable, talking muffled, must remove to eat & drink, becomes hot
Term
O2 Supplementation - Venturi Mask
Definition
%O2: 24% - 50%, flow rate controlled by color coded caps
Nursing Implications: ensure flow rate is set at the rate specified
Indications: when patient needs a more precise FiO2 to be delivered
Disadvantages: uncomfortable, talking muffled, must remove to eat & drink, becomes hot
Term
CPAP
Definition
  • Continuous Positive Airway Pressure
  • Pressure keeps airways open during inspiration when muscles collapse
  • Used most often with sleep apnea (also with premature infants)
  • BiPAP uses two levels of pressure, one for inspiration and another for expiration
Term
Incentive Spirometer
Definition
  • Measures inhalations
  • Useful to teach patients to deep breath and cough
  • Used for patients who are at high risk for atelectasis or pneumonia
Term
Rhonchi
Definition
 low-pitched, continuous gurgling sounds
caused by secretions in the large airways. They often
clear with coughing. (Bronchitis, Emphysema, Narrowed airways, Fibrotic lungs)
Term
Crackles
Definition
 Caused by air bubbling through 
moisture in the alveoli. Bubbling, crackling, popping. Soft, high-pitched, and very brief sounds, usually heard during inspiration. (Pneumonia, Congestive heart failure, Bronchitis, Emphysema)
Term
Stridor
Definition
Partial upper airway obstruction or tracheal or laryngeal
spasm. High-pitched, continuous honking sounds heard throughout the respiratory cycle but most
prominent on inspiration.  (Acute respiratory distress,
Foreign body in airway, Epiglottitis)
Term
Stertor
Definition
 labored breathing that produces a
snoring sound.
Term
Wheezes
Definition
Narrowing of small airways by spasm, inflammation, mucus, or tumor. High-pitched musical or squeaking sounds heard during inspiration or expiration. (Acute asthma, Emphysema)
Term
Bronchial or tubular sounds
Definition
Heard over the trachea. Blowing, hollow sounds;
inspiration is shorter than expiration and lower-pitched.
Term
Bronchovesicular sounds
Definition
Heard over the 1st and 2nd ICS anteriorly and over the scapula posteriorly. Medium-pitched, medium intensity, blowing sounds; inspiration and expiration are equal length and similar pitch
Term
Vesicular sounds
Definition
Heard over the lung periphery. Soft, low-pitched sounds;
inspiration is longer, louder, and higher-pitched than expiration
Term
Friction Rub
Definition
Rubbing together of inflamed pleural layers. A high-pitched grating or rubbing sound that may be heard throughout the respiratory cycle. Loudest over lower lateral anterior surface. (Pleuritis)
Term
Grunting
Definition
Retention of air in the lungs. A high-pitched tubular sound
heard on expiration. (Emphysema)
