77
What are the nursing responsibilities in receiving a medication order ?
A medication order is required for any medication administered by the nurse •Check all transcribed orders against the prescriber’s order •Ensure that the prescription has all the necessary components •Assess patient’s history of allergies •Give medication within 30 minutes
78
What are the nursing responsibilities in administering medication ?
During your assessment, you are accountable for determining that the medication prescribed is appropriate for the client. You must be knowledgeable about the factors that influence the administration of a particular drug, such as: a client’s age a client’s weight laboratory results or the need for a medication to be taken with food. For example, you should know of a client’s allergies or other sensitivities that contraindicate the administration of a medication. If you determine the medication is inappropriate, you must withhold it and talk with the prescriber in a timely manner. •Correctly identify patient •Inform patient of drug’s name, purpose, action, and side effects •Respect patient’s right to refuse medication •Discard unused medication once it has been removed from the container •Remain with the patient until medication is taken
79
What “three checks” are required when preparing medication?
Before administering medication, it is critical to have five areas of information correct: patient identification, medication, dosage, time, and route. But, it's not only critical to ensure this information is correct, you should check three times: 1. The first check is when the medications are pulled or retrieved from the automated dispensing machine, the medication drawer, or whatever system is in place at a given institution. 2. The second check is when preparation of the medications for administration takes place. 3. The final check occurs at the patient's bedside just before medications are given. This is also an outstanding opportunity to teach the patient about the medications.

81
When is it appropriate to “crush” a medication and which medications should never be crushed?
A common reason for crushing a tablet or capsule is for use by a hospitalized patient with an enteral feeding tube. A recent review in the American Journal of Health-System Pharmacy provides more details about administering medications in patients with enteral feeding tubes.2 Oral solutions can be used when commercially available and medically appropriate. If an oral solution or suspension is not available, the hospital pharmacy should be consulted to determine if a liquid formulation of the product can be extemporaneously prepared. In some cases, after careful consideration of compatibility, stability, and drug absorption changes, an injectable formulation of a product may be used. You should always consult your hospital pharmacist for information on this modality of drug administration. Some patients have difficulty swallowing tablets or capsules; some dislike the taste. In these cases, crushing of medication for powdered delivery (to be mixed with food or beverages) should be considered. But beware of certain caveats, as not all medications are suitable for crushing. Generally, meds that should not be crushed fall into one of these categories: • Sustained-release tablets, which can be composed of multiple layers for different drug release times, as can beads within capsules. • Enteric-coated tablets, which are formulated because certain drugs can be irritating to the stomach or are degraded by stomach acid. By enteric-coating tablets or capsule beads, the drug’s release can be delayed until it reaches the small intestine.
82
When is it appropriate to halve a tablet or caplet?
Pill-splitting refers to the practice of modifying a tablet, capsule or pill to obtain a lower dose of the active ingredient, or to obtain multiple smaller doses, because the drug is not available in the dose desired. Often, pills that are meant to be split (Aspirin for instance) come pre-scored so that one may easily divide the pill into halves or quarters.
83
How can you decrease a medication’s unpleasant taste?
Mix the drug with a small amount (about 1 teaspoon) of a sweet-tasting substance, such as jam, applesauce, sherbet, ice cream, or fruit puree. Do not use honey in infants because of the risk for botulism.
84
,How can you facilitate the administration of oral medications to a debilitated client?
1 Perform hand hygiene. 2 If the medication is not compatible with the feeding solution, or if patient needs to take medication on an empty stomach, stop the feeding 15 to 30 minutes before medication 3 Prepare medications for instillation into feeding tube. Check label against MAR three times (see Skill 21-1). Fill graduated container with 50 to 100 mL of tepid water. a Crush tablets using a pill-crushing device to grind pills into a fine powder. If a pill-crushing device is not available, place tablet between two medication cups and grind with a blunt instrument. Dissolve in at least 30 mL of warm water. b Capsules: Ensure that contents of capsule (granules or gelatin) can be expressed from the covering (consult with pharmacist). Open capsule, or pierce gelcap with sterile needle, and empty contents into 30 mL of warm water. You can also dissolve gelcaps in warm water. 4 Identify patient using two identifiers and comparing these identifiers with the information on patient’s identification bracelet. Ask patient to state name. Check name on patient’s identifi cation bracelet. 5 Prepare patient by placing in a high-Fowler’s position (if not contraindicated by patient’s medical condition). 6 Apply clean gloves 7 If a continuous enteric tube feeding is infusing, adjust the infusion pump to hold the tube feeding. 8 Check placement of feeding tube by observing gastric contents and checking pH of aspirate contents. Gastric pH should be 4 or less 9 Check for gastric residual. Connect syringe to end of feeding tube, then pull back slowly to aspirate gastric contents. Return aspirated contents to stomach. 10 Pinch nasogastric/enteric tube, and remove syringe. Draw up 30 mL of water in syringe. Reinsert tip of syringe into nasogastric/ enteric tube, and flush tube. Pinch tube again, and remove the syringe. Flushing ensures tube is patent. a Some nasogastric/enteric tubes are connected to continuous feeding tubing with a stopcock apparatus, such as a Lopez valve, that contains a medication port (see illustration). If present, attach the tip of the syringe to the medication port on the stopcock, and turn the “off” setting of the stopcock away from patient and toward the infusion tubing. Flush the enteric tube, then set stopcock “off” again to the medication port. Remove the syringe. 11 Remove bulb or plunger of syringe. Reinsert syringe into enteric tube (or medication port). 12 Administer first dose of dissolved medication by pouring into syringe. a) If giving only one dose of medication, fl ush with 30 mL of water after administration. b To administer more than one medication, give each separately, and flush between medications with 15 to 30 mL of water. c Follow last dose of medication with 30 to 60 mL of water. 13 When a tube feeding is not being administered, clamp the proximal end of the feeding tube, and cap end of tube. 14 When continuous tube feeding is being administered by an infusion pump: a Follow medication administration Steps 1 to 12. If the medications are not compatible with the feeding solution, then hold the feeding for an additional 30 to 60 minutes. 15 Assist patient to comfortable position, but keep the head of the bed elevated for 1 hour after administering the medication. 16 Dispose of soiled supplies, rinse graduated container and syringe with tap water, remove and dispose of gloves, and perform hand hygiene.
85
List some factors that contribute to medication errors.
A medication error is any event that could cause or lead to a client either receiving inappropriate medication therapy or failing to receive appropriate medication therapy. Most errors made by nurses are medication errors. A medication error can cause or lead to inappropriate medication use or client harm. A medication error can occur when you neglect routine procedures, such as checking dose calculations; administer unfamiliar medications; neglect to administer an ordered medication; fail to comply with the seven rights of medication administration; and fail to perform necessary assessments before medication administration (e.g., monitoring the client’s blood glucose levels or blood pressure). Additional system issues that can lead to medication errors include distraction, illegible orders, transcription errors, and inappropriate use of abbreviations. Hospital medication delivery systems should be designed so that a system of checks and balances help reduce medication errors. prepare for only one patient at a time, do not used unmarked/illegible containers, do not allow interruptions and double check calculations
86
What are the differences in medication administration for infants, children, adults, and older adults.
Calculating children’s medication doses requires caution. Children metabolize medications at different rates compared with adults. Other factors that influence medication dosages in children include the difficulty in evaluating the desired effect and the hydration status of the child. In most cases the prescriber will calculate the dose for a child before ordering the medication. However, it is your responsibility to be aware of the safe dosage range for any medication administered to a child. Older adults require special consideration during medication administration. The changes of aging alter pharmacokinetics (Table 20-3). As a result, nurses caring for older adults must be aware of drug dosing and alterations in drug response (Hunter and Cyr, 2006). Chronic disease is more prevalent among older adults, and multiple disease states also affect medication use and response. A common problem for older adult patients is polypharmacy, the use of a number of different medications, prescribed or not, for one or more health problems (McKenry and others, 2006).When several medications have similar effects, polypharmacy increases the chances of medication interactions. These interactions can be mistaken as medication toxicity, an increase in disease severity, suboptimal treatment, or an unrelated event. Review the special considerations associated with the administration of controlled substances and experimental drugs.
87
An appropriate administration route depends on?
1. the dosage form in which the drug is available 2. the patient’s age 3. the patient’s condition, e.g. level of consciousness, etc.
88
Each route of administration has distinct advantages and disadvantages. The same drug administered via a certain route
1. may be therapeutic 2. or the same drug may be a. ineffective b. harmful c. sometimes even fatal
89
Some drugs are approved for use via more than one route and are manufactured in more than one dosage form appropriate for these routes, e.g.
1. sublingual tablets 2. sublingual spray 3. ointment for transdermal application 4. intravenous solution for infusion
90
oral – the most convenient and most commonly used route of administration List advantages:
1. examples are tablets, capsules, and liquids 2. patients with dysphagia can usually swallow liquids without problems 3. infants may be given drugs in liquid form mixed with some formula or juice in a nipple 4. unconscious patients can receive liquid medications via NG tube (nasogastric) 5. oral route usually abbreviated as p.o. or PO (Latin per os, meaning through the mouth.)
91
oral – the most convenient and most commonly used route of administration List Disadvantages:
1. some drugs, especially certain penicillins, cannot be administered orally as they become inactivated by the stomach acid, therefore must be administered via intramuscular or intravenous injection. 2. some drugs are so quickly metabolized by the liver after oral administration that as they pass through the portal circulation that therapeutic levels cannot be reached in the systemic circulation. These drugs must be administered via intravenous injection, e.g. lidocaine (Xylocaine) for cardiac dysrhythmias 3. some drugs combine chemically with certain foods or beverages to form an insoluble complex or interact to produce adverse side effects, e.g. tetracycline cannot be taken with dairy products
92
Describe intradermal injection:
injection of a liquid into the dermis, just below the epidermis; when correctly administered the tip of the needle is still visible through the skin, e.g. Mantoux test for TB
93
Describe subcutaneous injection:
injection of a liquid into the fatty layer of tissue just below the dermis of the skin but above the muscle layer 1. slower absorption of the drug because only few blood vessels in this layer as compared to intramuscular injection, e.g. insulin, heparin, allergy shots 2. no official abbreviation but commonly accepted are: s.q., SQ, subQ, s.c., S.C., or subcu
94
Describe intramuscular injection:
injection of liquid into the belly (area of greatest mass) of a large muscle 1. large muscles well supplied with blood vessels 2. provides for more rapid absorption than via subcutaneous injection 3. only five intramuscular injection sites that allow for administration with lowest risk of damage to adjacent nerves and blood vessels a. deltoid – located on upper arm, lateral aspect b. vastus lateralis – located on midthigh, lateral aspect c. rectus femoris – located on midthigh, anterior aspect d. . ventrogluteal – located on the side of the hip over gluteus muscle between anterior and superior spines of the iliac crest e. dorsogluteal – located over gluteus minimus and edge of gluteus maximus muscles in upper outer quadrant
95
Valium, Librium are drugs that:
are not water soluble and would precipitate out in muscular tissue, therefore are not acceptable to be administered intramuscularly
96
Describe intravenous injection:
1. therapeutic effect can be seen immediately 2. drug does not need to be absorbed Examples are: a. Pantothal for induction of general anesthesia b. Valium for control of continuous epileptic seizures c. chemotherapy drugs for cancer treatment d. antibiotics in high dosages
97
IV injection can be accomplished in three ways:
I.V. push - the administration of a drug bolus by injecting a single dose of drug directly into the vein or through a port (rubber stopper) into an existing intravenous line in a very short time b. I.V. drip - mixing the drug with fluid in an I.V. bag or bottle to be administered continuously over several hours c. I.V. piggyback – mixing the drug in a very small I.V. bag or bottle connected through tubing to a port in the existing primary I.V
98
