Which site is most commonly used for intramuscular injections in adults due to accessibility and muscle thickness?
Deltoid muscle
Dorsogluteal region
Vastus lateralis muscle
Abdomen
The deltoid muscle is easily accessible and has sufficient muscle thickness for most adult intramuscular injections. It is preferred for quick administration and minimal patient discomfort. Other sites are used when large volumes or alternative locations are needed.
What is the recommended antiseptic preparation for an injection site?
70% isopropyl alcohol swab
Povidone - iodine scrub
Hydrogen peroxide rinse
Chlorhexidine foam only
A 70% isopropyl alcohol swab effectively reduces the skin's microbial load quickly and is standard for routine injections. While povidone - iodine is also antiseptic, it is less commonly used for simple in-home injections. Hydrogen peroxide and chlorhexidine foam alone are not the first-line prep in this setting.
What is the first step in hand hygiene before preparing an injection?
Wash hands with soap and water or alcohol-based rub
Don sterile gloves
Put on a face mask
Disinfect the work surface
Proper hand hygiene, using soap and water for at least 20 seconds or an alcohol-based hand rub, is the first critical step to reduce microbial transmission. Donning gloves is done after hand hygiene. Masking and surface disinfection are separate precautions.
Where should used needles and syringes be disposed of after an in-home injection?
A puncture-resistant sharps container
Regular household trash
Recyclable plastic bin
Laundry hamper
Sharps containers are specifically designed to safely contain used needles and syringes to prevent needlestick injuries and contamination. Regular trash or recycling is unsafe and against guidelines. Laundry hampers are inappropriate for sharps disposal.
What is the critical check before drawing medication into a syringe?
Verify the medication label, dose, and expiration date
Ensure the patient has eaten
Confirm the weather conditions
Check the syringe color
Verifying the medication label against the order, confirming the correct dose, and checking the expiration date are essential to ensure patient safety. The other options are unrelated to medication preparation. Syringe color is not a standard check.
At what angle should a subcutaneous injection typically be administered when using a longer needle?
45 degrees
30 degrees
90 degrees
15 degrees
A subcutaneous injection is usually given at a 45° angle when a longer needle is used to ensure the medication is deposited into the fatty tissue. Shorter needles may allow a 90° approach. 30° and 15° angles are not standard.
Why is it important to rotate subcutaneous injection sites over time?
To prevent lipodystrophy and tissue damage
To improve patient comfort instantly
To reduce needle cost
To increase absorption speed
Rotating sites prevents lipodystrophy - hard or soft tissue changes - from repeated injections in the same area. While comfort and absorption may be slightly affected, the main reason is tissue health. Rotation does not affect needle cost.
Which aseptic technique helps avoid contamination when handling a syringe?
Avoid touching the needle shaft or hub
Tap the plunger repeatedly
Use bare hands for better dexterity
Recap the needle after drawing medication
Not touching the needle shaft or hub preserves the sterility of the injection pathway. Tapping or recapping can introduce contamination. Using bare hands without gloves is unsafe, and recapping needles increases needlestick risk.
If a patient needs a 100 mg dose of a drug with a strength of 50 mg/mL, how many milliliters should you draw?
2 mL
0.5 mL
1 mL
4 mL
At 50 mg/mL, you need 100 mg, so 100 mg ÷ 50 mg/mL = 2 mL. The other volumes would underdose or overdose the patient.
Which needle gauge is most appropriate for an insulin subcutaneous injection to minimize pain?
31 gauge
18 gauge
21 gauge
23 gauge
Insulin injections use very fine needles, typically 30 - 31 gauge, to reduce patient discomfort. Larger gauges (lower number) are thicker and cause more pain. 21 - 23 gauge needles are used for other types of injections.
When confirming patient identity before injection, the best practice is to:
Ask the patient to state their full name and date of birth
Refer to the chart photo only
Rely on family member confirmation
Use room number as the identifier
Asking the patient to state their full name and date of birth confirms identity directly and reduces errors. Relying solely on charts, family, or room numbers can lead to misidentification.
What action should you take immediately after administering an injection?
Apply gentle pressure with sterile gauze
Massage the area vigorously
Leave the needle in place for one minute
Bandage without pressure
Applying gentle pressure prevents bleeding and helps distribute the medication without causing tissue irritation. Vigorous massage can increase bruising, and leaving the needle in place is unsafe.
Which sign at an injection site indicates a potential infection?
Redness, warmth, and swelling
Light bruising only
Minor itching without redness
Dryness and flaking skin
Redness, warmth, and swelling signal inflammation and possible infection. Bruising or minor itching alone are less indicative of infection. Dry skin without other signs is not infection-related.
How should temperature-sensitive injectable medications be stored in the home setting?
In a refrigerator at 2 - 8 °C
In a freezer below 0 °C
On a countertop at room temperature
Under direct sunlight
Most temperature-sensitive injectables require refrigeration between 2 °C and 8 °C. Freezing can damage the product, while room temperature or sunlight may degrade potency.
What is the correct way to prime an insulin syringe before injection?
Tap out air bubbles and expel a drop of insulin
Fill past the dose and push the plunger to zero
Shake vigorously to mix air
Heat the syringe in your hand first
Tapping out air bubbles and expelling a small drop of insulin ensures accurate dosing by removing trapped air. Overfilling, shaking, or warming the syringe are unsafe or ineffective methods.
A patient requires 75 mg of a medication supplied as 25 mg per 0.5 mL. How many milliliters should you draw?
1.5 mL
0.75 mL
2 mL
1 mL
First calculate concentration: 25 mg/0.5 mL = 50 mg/mL. Then 75 mg ÷ 50 mg/mL = 1.5 mL. The other volumes would deliver incorrect doses.
Which practice aligns with updated guidelines for intramuscular vaccine administration regarding aspiration?
Do not aspirate before injection
Always aspirate for 10 seconds
Aspirate only in pediatric patients
Aspirate if no blood return is seen
Current guidelines recommend not aspirating for routine intramuscular vaccinations because no large blood vessels are present at recommended sites. Aspiration can increase discomfort and delay injection.
If a patient feels dizzy immediately after injection, what is the most appropriate immediate action?
Have them sit or lie down and monitor vital signs
Administer a sugary snack immediately
Encourage them to walk around
Apply a cold compress to the forehead
Sitting or lying down prevents falls and allows monitoring for syncope or hypotension. Walking or unrelated interventions do not address the risk of fainting after an injection.
What is the first step if you sustain a needlestick injury during an in-home injection?
Wash the area with soap and water
Squeeze the wound to draw out blood
Apply a tourniquet above the injury
Ignore it and continue
Immediate washing with soap and water reduces infection risk. Squeezing, tourniquets, or ignoring the injury can worsen outcomes and delay proper post-exposure management.
Which instruction is most appropriate for post-injection care of intramuscular injections?
Apply a cold compress to reduce swelling
Massage the site to enhance absorption
Keep the limb elevated for 24 hours
Expose to heat to soothe pain
A cold compress helps minimize pain and swelling by constricting blood vessels. Massage can irritate tissue, and heat may increase inflammation. Elevation is unnecessary for most IM injections.
