Responsibilites of the nurse when administering medication
-what drug is ordered -name (generic and trade) and drug classification -intended or proposed use -effects on the body -contradictions -special considerations (e.g., how age, weight, body fat distribution, and individual pathophysiologic states affect pharmacotherapeutic response) -side effects -why the medication has been prescribed for this particular patient -how the medication is supplied by the pharmacy -how the medication is to be administered, including dosage ranges -what nursing process considerations related to the medication apply to this patient
Allergic Reaction
-an acquired hyperresponse of body defesnes to a foreign substance (allergen) -signs of allergic reactions vary in severity and include skin rash with or without itching, edema, runny nose, or reddened eyes with tearing
Anaphylaxis
-a sever type of allergic reaction that involves the massive, systemic release of histamine and other chemical mediators of inflammation that can lead to life threatening shock -symptoms such as acute dyspnea (difficulty breathing), and the sudden appearance of hypotension or tachycardia following drug administration are indicative of anaphylaxis which must recieve immediate treatment
The Five Rights of Drug Administration
-together, they form the operational basis for the safe delivery of medications -offer simple and practical guidance for nurses to use during drug preparation, delivery, and administration, and focus on individual performance
right patient
right medication
right dose
right route of adminitration
right time of delivery
can also include: -right to refuse medication, the right to recieve drug education, the right preparation, and the right documentation
The Three Checks of Drug Administration
-used in conjuction with the five rights help to ensure patient safety and drug effectiveness
checking the drug with the MAR or the medication information system when removing it from the medication drawer, refrigerator, or controlled substance locker
checking the drug when preparing it, pouring it, taking it out of the unit-dose container, or connecting the IV tubing to the bag
checking the drug before administering it to the patient
Compliance
-taking a medication in the manner prescribed by the health care provider, or in the case of OTC drugs, following the instructions on the label -patient noncompliance ranges from not taking the medication at all to taking it at the wrong time or in the wrong manner
Reasons for noncompliance
-drug may be too expensive -the drug may not be approved by the patient's health insurance plan -patients forget doses of medications, especially when they must be taken three or four times per day -annoying side effects such as; headache, dizziness, nausea, diarrhea, or impotence (erectile dysfunction) -impair major lifestyle choices
-patients may self-adjust their doses --some patients believe that if one pill is good, two must be better -others believe that they will become dependent on the medication if they take it as prescribed so they only take half of the required dose
STAT order
-refers to any medication that is needed immediately and is to be given only once -often associated with emergency medications that are needed for life-threatening situations -comes from the latin word "statim" meaning immediately -should be administered within 5 minues or less of recieving the written order
ASAP order
-not as urgent as STAT -as soon as possible -should be avaliable for administration to the patient with 30 minutes of the written order
Single order
-for a drug that is to be given only once, and at a specific time, such as a preoperative order
PRN order
-latin "pro re nata" -administered as required by the patient's condition -the nurse makes the judgement, based on patient assessment, as to when such a medication is to be administered
Routine orders
-orders not written as STAT, ASAP, NOW or PRN -these are usually carried out within 2 hours of the time the order is written by the physician
Standing order
-written in advance of a situation that is to be carried out under specific circumstances -example: set of postoperative PRN prescriptions that are written for all patients who have undergone a specific surgical procedure "Tylenol elixir 325mg PO every 6 hours PRN sore throat" -standing orders are no longer permitted in some facilites because of the legal implications of putting all patients into a single treatment category

Enteral Drug Administration
-includes drugs given orally and those administered through the nasogastric or gastrostomy tubes -take advantage of the vast absorptive surfaces of the oral mucosa, stomach, and small intestine
Oral Drug Administration
-oral dugs administration is the most common, most convienient, and usually the least costly of all routes -considered the safest route because the skin barrier is not compromised -avaliable in tablet, capsule, and liquid forms
Tablets and Capsules
-the most common forms of drugs -patients prefer tablets or capsules over other routes and forms because of their ease of use -some patients, especially children, have difficulty swallowing tablets and capsules -crushing tablets or openings capsules and sprinkling the drug over food or mixing it with juice will make it more palatable and easier to swallow -do not crush tablets or open capsules inless the manufacturer specifically states this is permissable -some drugs are inavtivated by crushing or opening, whereas others severely irritate the stomach mucosa and cause nausea or vomiting -some drugs can irritate the oral mucosa, are extremely bitter, or contain dyes that stain the teeth
Enteric Coated Drugs
-the strongly acidic contents within the stomach present a destructive obstacle to the absorption of some medications -tablets may have hard, waxy coatings that enables them to resist the acidity -enteric coated tablets are designed to dissolve in the alkaline environment of the small intestine -do not crush these drugs because the medication would then be directly exposed to the stomach environment
Sustained Release Drugs
-compliance declines as the number of doses per day increases -sustained release tablets or capsules are designed to dissolve very slowly -this releases the medication over an extended time and results in longer duration of action for the medication -also called extended-release (XR), long-acting (LA), or slow-release (SR) medications, these forms allow for convienience of once-or-twice-a-day dosing -extended release medication must not be crushed ot opened
