When should calcium supplements be given?

1 hr before or 1 hr after... glucocorticoids (decreases absorption of ca) thyroid supplements (ca decreases absorption of these) Tetracycline and Quinolone antibiotics (ca decreases absorption of these) Thiazide diuretics decrease excretion of ca Give 1 hr after meals

Four Categories of Pharmacokinetic Processes

1. Absorption -Movement from site of administration, across body membranes, to circulating fluids. Primary pharmacokinetic factor determining length of time for drug to produce effect. 2. Distribution - transport of drugs throughout the body. Simplest factor determining distribution is the amount of blood flow to body tissues.Physical properties of drug have great influence. Certain tissues (bone marrow, teeth, eyes, adipose tissue) have a high affinity, or attraction, for certain medications. Many drug molecules form drug protein complexes-binding reversibly to plasma proteins and thus never reach target cells. 3. Metabolism (aka -biotransformation) -Chemically converts drug so it can be easily removed from body. Involves complex biochemical reactions. Liver — primary site. Addition of side chains, known as conjugates, makes drugs more water soluble and more easily excreted by the kidneys. 4. Excretion -how drugs are removed from the body. Rate at which medications are excreted determines the concentration of the drugs in the bloodstream and tissues.

Three Checks of Drug Administration

1. Checking drug with MAR (medical administration record) or medication information system when removing it from storage 2. Checking drug when preparing it 3. Checking drug before administering it to the patient

** Oral Drugs Enter Hepatic Portal Circulation (First-Pass Effect)

1. Drug is absorbed 2. Drug enters hepatic circulation, goes to liver 3. Drug is metabolized to inactive form 4. Drug conjugates and leaves liver 5. Drug is distributed to general circulation 6. Many drugs are rendered inactive by first-pass effect

Drug Label 1. Mycobutin (rifabutin) 2. capsules 3. NDC 0013-5301-17 4. Bar code 5. 150 mg 6. Usual Dosage: Two capsules in a single daily administration. For additional prescribing information read package insert. 7. USP 8. Store at 25 degrees Celsius (77 degree Fahrenheit) excursions permitted to 15-30 degrees Celsius (59-86 Fahrenheit) see USP Controlled Room temperature. 9. expiration date 10. Manufacturer

1. Name of drug: What is trade name of this drug? What is the generic name of this drug? 2.Form of drug:. 3. National Drug Code (NDC) number 4.Bar code: Has the NDC number encoded in it. 5. Dosage Strength:What is the dosage strength of this drug? 6. Dosage recommendations: What is the recommended dosage? 7. USP: This drug meets the standards of the United States Pharmacopeia. 8. Storage directions: Some drugs have to be stored under controlled conditions if they are to retain their effectiveness. How should this drug be stored? 9. Expiration date: The expiration date specifies when the drug should be discarded. What is this drugs expiration date? 10. Manufacturer:

Nursing Diagnoses for Drug Administration

1. Often most challenging part of nursing 2. Focus is on patient's needs, not nurse's 3. Three main areas of concerns - Promoting therapeutic drug effects - Minimizing adverse drug effects and toxicity - Maximizing patient ability for self-care (including knowledge, skills, and resources necessary for safe and effective drug administration)

Nurse Planning Phase

1. Planning - Prioritizes nursing diagnosis - Formulates desired outcomes - Selects nursing interventions that can assist patient to establish an optimum level of wellness. - Create goals/outcomes; be sure goals are SMART!

Four Stages of Approval for Therapeutic and Biologic Drugs

1. Preclinical investigation (1-3 years, average 18months) 2. Clinical investigation (2-10 years; average 5 years) 3. Review of new drug application (NDA) (2 months -7 years, average 24 months) 4. Postmarketing surveillance (adverse reaction reporting; surveys/sampling/testing; inspections)

Excretion of Medications

1. Primary Site of Excretion of Drugs Is Kidneys 2. Free drugs, water-soluble agents, electrolytes, and small molecules are easily filtered 3. Drug-protein complexes and large substances are secreted into distal tubule of nephron 4. Secretion mechanism is less active in infants and older adults

How Drug Reaches and Maintains Therapeutic Range

1. Repeated doses of drug are given 2. Drug accumulates in bloodstream 3. Plateau is reached 4. Amount administered equals amount eliminated

Five Rights of Drug Administration

1. Right patient 2. Right medication 3. Right dose 4. Right route of administration 5. Right time of delivery Right documentation

Assessment of the Patient

1. Systematic collection, organization, validation, and documentation of patient data 2. Health history and physical assessment 3. Baseline data gathered; will be compared to later information from observations 4. Once pharmacotherapy is initiated, assessment focuses on reaction to medication. Watch for: desired response, adverse effects, patient capability of assuming responsibility for self-administration

Common Protocols and Techniques for All Routes of Administration

1. Verify medication order, check allergy history 2. Wash hands and apply gloves, if indicated 3. Use aseptic technique when preparing and administering parenteral medications 4. Identify patient (two forms of ID) 5. Ask patient about known allergies 6. Inform patient about drug 7. Position patient 8. Remove prepackaged drug at bedside 9. Unless instructed to do so, do not leave drugs at bedside 10. Document administration and pertinent patient responses

2 Recheck blood glucose in 15 min. 3 Give 7 g of protein. 1 Give 15 to 20 g of carbohydrates. 4 Report episode to the provider. The greatest risk to the client is a lack of glucose for cell metabolism. Therefore, the priority action is to give 15 to 20 g of carbohydrates (4 oz orange juice, 2 oz grape juice, 8 oz milk) to raise the client's serum blood glucose level. Next, the client's blood glucose should be checked in 15 min. If the blood glucose remains below 70 mg/dL, give 15 g more of carbohydrates. Recheck the client's blood glucose in 15 min. Repeat until the client's blood glucose is above 70 mg/dL. Follow with 7 g of protein. Report findings to the client's provider and document actions.

"Do not allow your baby to drink anything after the digoxin is administered." B. "Digoxin speeds the heart rate up to allow the heart to pump out more fluid." C. "It is important to administer the correct amount at regularly scheduled times." D. "If your baby vomits a dose, you should repeat the dose to ensure that he gets the correct amount."

C. "It is important to administer the correct amount at regularly scheduled times." The correct amount of digoxin should be administered at regularly scheduled times to maintain therapeutic blood levels. If the infant has teeth, the dose should be followed by water to prevent tooth decay. Digoxin slows the heart rate. If the infant vomits after the dose, it should not be re-administered because there is no way to know if the infant received any of the medication.

Eat a snack prior to planned exercise. Inspect feet surfaces daily.

Carry a fast-acting glucose source at all times. Eat a snack prior to planned exercise. Inspect feet surfaces daily. A client who has diabetes should always carry a fast-acting glucose source to treat unexpected hypoglycemia. Active muscle cells can take in glucose without insulin, and therefore prior to exercising the client should eat a snack to ensure enough glucose is available to prevent hypoglycemia. A client who has diabetes should inspect his feet daily to monitor for skin breakdown and signs of infection. A client who has newly diagnosed diabetes should check blood glucose levels at least before meals and at bedtime, and more frequently when ill as acute illness can lead to hyperglycemia. The client should not take an extra dose of medication if a dose is missed.

Drug Administration

In order to prepare and administer drugs, it is imperative that you understand and follow the "Six Rights of Medication Administration" • Right dose - In order to avoid medication errors, always complete three checks when preparing medications 1. When reaching for the container 2. Immediately before preparing the dose 3. When replacing or discarding the container • Right Route -Medications must be administered in the form and via the route specified by the prescriber. Right Time - The prescriber will indicate when and how often a medication should be administered. - Medications can be ordered once a day (daily), twice a day (b.i.d.), three times a day(t.i.d.), or four times a day (q.i.d.). Right Patient - Before administering any medication, it is essential to determine the recipient's identity.
