What does the book list as parenteral routes of medication administration?

a device that forces room air or oxygen into the lungs, even when the patient forgets to breathe. it is ideal for patients with sleep apnea, in which the patient stops breathing for short periods of time while asleep.

What is a CPAP and who needs it?

tablets that have added antacids to prevent stomach irritation.

What is a buffered tablet?

MDIs are used to deliver specific doses of medication through a hand-held inhalation device.

What is a meter dosed inhaler and how is it used?

Explain that timed-released capsules cannot be opened or crushed because doing so releases the drug all at once, causing an overdose

Oral Liquid Medications

Easier to swallow than solid and absorbed quicker

It will have ER, XR, or XL following the name

How can you tell if a medication is extended release

To decrease discomfort, ear medications should be at room temperature before they are given. To decrease discomfort, ear medications should be at room temperature before they are given. the patient must keep the affected ear upright for a few minutes to allow maximum absorption of the medication. Adults should pull the pinna up and back; the outer ear should be pulled down and back in children, to straighten the ear canal for best absorption.

How do you administer ear drops to both young and old?

Wear gloves and be careful not to touch the dropper to the eye or eyelid itself. Have the patient look upward as you drop in the exact number of drops ordered. After the drops are instilled, have the patient close his or her eyes. Applying light pressure with a finger on the inner part of the closed eyelid after administration of the medication also helps to keep the drug from leaking into the nasolacrimal duct.

How do you administer eye drops?

Apply to the inside of the bottom eyelid or conjunctival sac. Pull down on the lower eyelid and apply the ointment stream from the inner (nasal) to outer aspect. You may need to use a twisting motion to break the ointment stream. Be sure not to touch the tip of the tube to the eye or eyelid.

How do you apply ointment to eyes?

1. Follow all steps from Procedure Box 10-9 up until actually inserting the needle. 2. Before inserting the needle, pull the skin laterally 1 inch away from the injection site (see Fig. 10-15). 3. Insert the needle at 90°, as for all IM injections. 4. Aspirate for blood return (accidental placement in a blood vessel) by pulling backward on the plunger if agency policy requires. 5. If no blood is noted, gently and slowly inject all medication. (If blood is noted, withdraw the needle, discard the syringe and needle, and start the procedure over with a clean needle and syringe.) 6. Wait 10 seconds before removing the needle, to allow medication to be absorbed deeply. 7. Remove the needle and syringe quickly at the same angle of insertion engaging the needle's safety device and place a cotton ball at the insertion site. 8. Quickly release traction on the Z-track position (see Fig. 10-15). This prevents medication from leaking back into more superficial tissues. 9. Dispose of the needle and syringe immediately in a sharps container. Do not recap. 10. Assess the patient and the injection site. 11. Cover the wound with an adhesive bandage. 12. Remove gloves and wash hands. 13. Docu

How is the Ztrack method done?

select the proper needle length and gauge and adjust the angle of injection to reach the appropriate tissue level. The usual sites for ID injections are the inner aspect of the forearm and the upper back. After preparing the site with an alcohol swab, hold the skin taut and insert the needle just under the epidermis at a 10° to 15° angle. Typically, a short, small-gauge (diameter) needle is used. If the injection is administered properly, a wheal will form

How to administer intradermal injections. Which sites are used?

eye drops first because because ointment forms a barrier that will not allow drops to penetrate.

If you have orders to apply both eye drops and ointment, which do you apply first and why?

1. Observe the seven "rights" of medication administration. 2. Read the order, and compare it with the label on the medication container. Check the expiration date. 3. Wash hands. 4. Compare the medication order with the container a second time. 5. Identify the patient, and explain what you will be doing. 6. Compare the order and the container a third time. 7. Put on gloves. 8. Inspect the application site, and make sure that it is clean, dry, and free of lesions. 9. Carefully remove the adhesive backing from the patch. 10. Place the patch on the selected site, and make sure that all edges of the adhesive adhere securely to skin. 11. Remove gloves and wash hands. 12. Document medication dosage, location, and the patient's response.

Warning labels

The pharmacist places them on the prescription container to make sure the patients understand the best way to take the medication and become aware of possible situations to avoid. the are usually a bright color to make sure they are not overlooked; examples include: Shake well; Keep refrigerated; For the ear; Take medication on an empty stomach; Do not drink alcoholic beverages when taking this medication; Do not crush; May cause drowsiness or dizziness

1. Observe the seven "rights" of medication administration. 2. Read the medication order, and compare it with the medication container. Check the expiration date. 3. Wash hands. 4. Compare the medication order with the container a second time. 5. Assess the patency of the nose dropper. 6. Identify the patient, and explain what you will be doing. 7. Compare the order with the container a third time. 8. Put on gloves. 9. Ask the patient to tilt his or her head backward. 10. Draw up medication into the dropper, as ordered. 11. Insert the dropper with medication into the nostril, as ordered. 12. Squeeze the dropper. 13. Ask the patient to maintain head tilt while you squeeze the nostril for a few moments, to prevent medication from leaking. 14. Assess the patient. 15. Remove gloves and wash hands. 16. Document dosage, site of placement, and the patient's response.

What are the steps for administering a nasal spray?

This equipment introduces the medication by using compressed air or oxygen to aerosolize or suspend medication into small particles in a fine mist for inhalation into the lungs through a face mask or mouthpiece. Commonly used by asthmatic patients and patients with cystic fibrosis

What is a nebulizer? What different types of patients need this?

an extension tunnel that attaches to an inhaler and allows the medication to be held and administered whenever the patient can inhale, rather than escaping into the air if the patient exhales instead of inhaling. especially useful for children and for adults who are cognitively impaired or disabled.
