Sheerpath Quiz 7 Parenteral and Syringe
The nurse is preparing to give an intramuscular injection. Which is the appropriately sized needle for this type of injection? 3-in 1- to 2-in ½- to ⅝-in ⅜- to ½-in
1 to 2 in Rationale A 1- to 2-in needle is appropriate. A 3-in needle is not used for intramuscular administration. A ⅜- to ½-in - to 5/8-in needle is used for a subcutaneous injection. A 3/8 to ½-in needle is used for intradermal injectio
The health care provider prescribes methylprednisolone 90 mg intravenously to a patient. The pharmacy sends a 125-mg (2-mL) vial. How many milliliters will the nurse administer? Record your answer using one decimal place. mL
1.4 Rationale The desired dose is 90 mg IV. The available amount is equal to the desired amount multiplied by the volume and divided by the amount on hand. Therefore, the nurse multiplies 90 mg by 2 mL, and then divides by 125 mg to get 1.44 mL, rounded to 1.4 mL.
A label on a mix-o-vial of Solu-Cortef states above the drug name that there are 2 mL in the container. Below the generic name of the drug, it says there are 100 mg of hydrocortisone sodium succinate. What is the dosage in this mix-o-vial? 2 mg/2 mL 2 mg/100 mL 100 mg/2 mL 100 mg/100 mL
100 mg/2 mL Rationale The volume is found above the drug name, and the dosage in milligrams is found underneath the trade and generic name of the drug on the vial; the correct amount in the packaging is 100 mg/2 mL. The dosage is 100 mg, not 2 mg, and the volume is 2 mL, not 100 mL.
The nurse is preparing to administer a loading dose of milrinone to a patient. The health care provider has prescribed 50 mcg/kg, and the patient weighs 198 lb. How many milligrams will the nurse administer? Record your answer using one decimal place. mg
4.5 Rationale First the nurse divides 198 lb by 2.2 kg to get 90 kg. The desired dose is 50 mcg/kg multiplied by 90 kg, or 4500 mcg. Then the nurse divides 4500 mcg by 1000 mcg to get 4.5 mg.
The health care provider has prescribed adriamycin 45 mg/m 2. The patient weighs 1.75 m 2. How many milligrams will the nurse administer? Record your answer using one decimal place. mg
78.8 Rationale The nurse multiplies 45 mg by 1.75 m 2 to get 78.75 mg. Rounded up to one decimal place, the nurse administers 78.8 mg.
The nurse is preparing to administer 2.3 mL of medication. Which is the most appropriate device for the nurse to choose? A 3-mL syringe A 10-mL syringe A tuberculin syringe An insulin syringe
A 3-mL syringe Rationale A 3-mL syringe would be most appropriate. A 10-mL syringe is too large. Tuberculin syringes and insulin syringes are used for low-dose medications and have needles that do not allow for intramuscular administration for a medication.
Which is most likely responsible for adverse effects experienced by a patient over 65? Age-related changes Decreased immune response Increased protein levels Decreased liver function
Age-related changes Rationale Age-related changes in serum albumin, gastric motility, and liver and kidney function impair drug absorption, distribution, metabolism, and excretion, increasing the risk for adverse effects. Decreased immune response, increased protein levels, or decreased liver function are less likely to contribute to adverse effects.
What parenteral medication packaging is found on the following medication label? Vial Ampule Mix-o-vial Cartridge
Ampule Rationale The upper right-hand corner of the label identifies it as an ampule. Nothing on the label indicates this medication is packaged in a vial, mix-o-vial, or cartridge.
The following image illustrates which type of parenteral medication packaging? Vial Ampule Cartridge Mix-o-vial
Cartridge Rationale This medication is in a cartridge syringe. Vials, ampules, and mix-o-vials require the medication to be withdrawn from the packaging system before administration, while a needle can be applied to the end of this syringe.
The nurse is educating a student nurse about information on parenteral medication labels. Which student nurse statement indicates effective learning? "I can find the reconstitution information on the label." "I should contact the prescribing health care provider for reconstitution information." "I will add 0.9% normal saline whenever I reconstitute medication." "I need to ask a coworker how to reconstitute all medications."
I can find the reconstitution information on the label." Rationale Reconstitution information will always be found on the label; therefore, this nursing student statement is correct and indicates effective learning. The health care provider may have some knowledge regarding reconstitution of medication, however the most reliable sources of this information are either the pharmacist or the manufacturer and is found on the medication label. Using 0.9% normal saline is not always correct for reconstituting medications, because some require sterile water. A coworker is not always the best source of information, and consulting one is unnecessary, because the reconstitution directions are accurate on the label.
The nurse is preparing to give a parenteral medication that is packaged in a vial. After verifying the correct medication and dosage, what is the nurse's priority action? Using a filter needle to withdraw the medication Using a needleless system to withdraw the medication Accessing an intravenous line to administer the medication Inserting air into the vial before withdrawing the medication
Inserting air into the vial before withdrawing the medication Rationale Air must be inserted into a vial before withdrawing the medication. A filter needle is not necessary when withdrawing medication from a vial. A needle will be required to withdraw the medication, so a needleless system is not useful. There is no information in the question to indicate that this medication will be given intravenously.
A patient is to undergo skin testing for allergies. What type of injection will the nurse prepare for this patient? Subcutaneous Intravenous Intradermal Intramuscular
Intradermal Rationale The intradermal injection is used for skin testing. Subcutaneous, intravenous, and intramuscular injections are more invasive than necessary for skin testing
A patient's prescribed medication arrives in a prefilled syringe. What does the nurse understand about the prefilled syringe? It comes prepared for administration. It contains the exact amount of medication ordered. It is a multidose syringe. It always requires attachment of a needle.
It comes prepared for administration. Rationale Prefilled syringes contain medication prepared for administration. The syringe contains a specific amount of medication; excess medication should be discarded before administration. Prefilled syringes are single-dose syringes, which may come with or without a needle.
The medication in the container in the image is an example of which kind of parenteral Vial Ampule Mix-o-vial Prefilled syringe
Mix-o-vial Rationale The medication powder and the fluid are separated by a plunger, which is consistent with the packaging of a mix-o-vial. Vials, ampules, and prefilled syringes do not separate powder and fluid.
The patient is to receive infliximab 5 mg/kg intravenously every 6 weeks. The patient weighs 220 lb. How much medication will the patient receive? Record your answer as a whole number. mg
Rationale First, the nurse divides 220 lb by 2.2 kg to get 100 kg. Then the nurse multiplies 100 kg by 5 mg/kg to get 500 mg.
The nurse is preparing to administer 3 mg morphine sulfate to a patient in pain. The medication is packaged in a 5-mg (1-mL) vial. How many milliliters will the nurse administer? Include a leading zero if applicable. Record your answer using one decimal place. mL
Rationale The desired dose is 3 mg and it is dispensed in a 5-mg (1-mL) vial. The nurse divides 3 mg by 5 my (1 mL) to get 0.6 mL.
The nurse is preparing to give a subcutaneous injection. Which is the appropriate needle for this type of injection? 18-gauge 20-gauge 25-gauge 28-gauge
Rationale 28 gauge A 28-gauge is used for a subcutaneous injection. An 18-gauge is used for intravenous administration. A 20-gauge is used for an intramuscular injection. A 25-gauge needle is appropriate for an intradermal injection.
The patient's medication is packaged in a cartridge that requires a Carpuject. What is a Carpuject? The name of the cartridge An insertion into the cartridge to remove the medication The holder required to release the medication A prefilled syringe
The holder required to release the medication Rationale A Carpuject is a special holder required by some cartridges to release the medication. A cartridge is what contains the medication. A needle may be inserted into the rubber stopper to remove a specific amount of medication from the cartridge. A prefilled syringe is a syringe filled with a prepared medication dose.
When administering an intradermal injection, the nurse understands that safe practice includes which factors? Needle aspiration Use of a 1-mL syringe Injection into the fatty tissue Insertion of the needle with the bevel up Insertion of the needle with the bevel down Administration of 1.5 mL of the medication
Use of a 1-mL syringe Insertion of the needle with the bevel up Rationale The maximum amount of medication that can be given in an intradermal injection is 1 mL. The needle should be inserted with the bevel up in order to pierce the skin first and not cause tissue damage. Aspiration should not be practiced with intradermal injections. Injection of medication into fatty tissue is reserved for subcutaneous injections; intradermal injections are injections of medication between the dermis and epidermis. Inserting the needle with the bevel down can cause tissue damage. Administering 1.5 mL of medication is too much.
The amount of heparin sodium to be administered is 5000 units/0.5 mL. Which type of syringe is appropriate for drawing up this medication? Insulin syringe 3-mL syringe Hypodermic syringe Tuberculin syringe
Tuberculin syringe Rationale The tuberculin syringe is a narrow syringe that has the capacity to hold 0.5 or 1 mL of medication. Tuberculin syringes are used to accurately measure medications given in small volumes. Insulin syringes are used to administer insulin and are calibrated in units rather than milliliters. A 3-mL syringe is used to deliver doses greater than 1 mL. "Hypodermic syringe" is a general term for any syringe.
The nurse is preparing to administer a parenteral medication that is packaged in an ampule. What is the nurse's priority action? Using a safety needle to withdraw the medication Using a needleless system to withdraw the medication Accessing an intravenous line to administer the medication Using a filter needle to withdraw the medication
Using a filter needle to withdraw the medication Rationale Although a safety needle should be used to give the medication, a filter needle is required to withdraw the medication from the ampule to ensure that no debris from the breaking of the bottle neck is in the solution. Following that, the nurse can use a safety needle. A needleless system cannot be used to withdraw the medication. There is not enough information in the question to assume that this medication would be given intravenously.
What parenteral medication packaging is found on the following medication label? Vial Ampule Cartridge Mix-o-vial
Vial Rationale "Single-dose vial" is printed on the medication label directly above the drug name. There is nothing on this label to indicate the medication comes in an ampule, cartridge, or mix-o-vial.
Which assessment does the accurate measurement of medication in a syringe require? The Raised of the suction tip on the plunger The bottom ring of the suction tip on the plunger Where the rubber plunger edge makes contact with the barrel The volume of medication at the milliliter mark
Where the rubber plunger edge makes contact with the barrel Rationale The point where the rubber plunger edge makes contact with the barrel indicates the correct amount of the medication in the syringe. The raised section and the bottom ring of the suction tip of the plunger are not accurate measurements of the medication in the syringe. The volume of medication at the milliliter mark should be assessed in conjunction with the point of the rubber plunger. Only assessing the volume of medication at the milliliter mark will not determine an accurate measurement.
The nurse is preparing to administer a parenteral medication. The medication is available in a glass container, which is scored at the neck. The nurse recognizes that the medication is packaged in what? Vial Mix-o-vial Ampule Prefilled syringe
ampule Rationale An ampule is a glass container that must be broken at the neck to access the medication. A vial is a plastic or glass container with a rubber stopper. A mix-o-vial is a glass or plastic container with a rubber stopper in the middle that separates the liquid and the powder medication. Medications in a prefilled syringe are premeasured and are single-dose medications.
The nurse is preparing to give an intradermal injection. Which is the appropriately sized needle for this type of injection? ⅜- to ½-in ½- to ⅝-in 1- to 2-in 3-in
⅜- to ½-in Rationale A ⅜- to ½-in needle is used for an intradermal injection. A ½- to ⅝-in needle is used for a subcutaneous injection. A 1- to 2-in needle is used for an intramuscular injection. A 3-in needle is not used for an intradermal administration.
