APHA Risk Management & Mitigation 3 — Questions and Answers
Question 1: A pharmacist discovers a multi-dose vial of influenza vaccine was left at room temperature for 6 hours. What is the most appropriate risk mitigation step?
- Return the vial to the refrigerator immediately and continue using it
- Discard the vial according to facility policy and document the excursion (Correct answer)
- Administer the remaining doses quickly before further degradation occurs
- Freeze the vial to restore potency
Correct answer: Discard the vial according to facility policy and document the excursion
Vaccines exposed to temperature excursions beyond manufacturer and CDC guidance should be discarded, and the event documented to prevent future errors.
Question 2: Which of the following is a TRUE statement about contraindications versus precautions in immunization?
- A precaution means the vaccine must never be given under any circumstances
- A contraindication generally warrants withholding the vaccine, while a precaution requires weighing risks and benefits (Correct answer)
- Contraindications and precautions carry equal clinical weight
- A precaution automatically becomes a contraindication if the patient is immunocompromised
Correct answer: A contraindication generally warrants withholding the vaccine, while a precaution requires weighing risks and benefits
Contraindications typically mean the vaccine should not be given, while precautions indicate a situation where benefits and risks must be carefully weighed before vaccinating.
Question 3: A patient who received the MMR vaccine 4 weeks ago needs a varicella vaccine. What risk consideration applies?
- No special timing is needed because MMR and varicella are both live vaccines
- Both vaccines should have been given simultaneously or the varicella must be delayed at least 4 weeks after MMR (Correct answer)
- The varicella vaccine is contraindicated in anyone who has received MMR in the past year
- The patient needs a varicella titer before proceeding
Correct answer: Both vaccines should have been given simultaneously or the varicella must be delayed at least 4 weeks after MMR
Two live vaccines not given simultaneously must be separated by at least 28 days; if the varicella was not given on the same day as MMR, it must be delayed 4 weeks.
Question 4: When completing a VAERS report after a serious adverse event, which information is considered essential to include?
- Manufacturer's lot number, vaccine administered, adverse event description, and patient demographics (Correct answer)
- Only the vaccine brand name and the patient's date of birth
- The pharmacist's license number and the prescribing physician's NPI
- Proof of causality established by a physician
Correct answer: Manufacturer's lot number, vaccine administered, adverse event description, and patient demographics
A complete VAERS report includes the vaccine name, lot number, patient demographics, adverse event details, and timing to help identify safety signals.
Question 5: Which strategy most effectively reduces the risk of vaccine administration to the wrong patient?
- Confirming the patient's name verbally when they enter the pharmacy
- Using at least two patient identifiers (e.g., name and date of birth) before vaccine preparation and administration (Correct answer)
- Relying on the patient's appointment record as the sole identifier
- Checking the patient's photo ID only if the pharmacist is uncertain
Correct answer: Using at least two patient identifiers (e.g., name and date of birth) before vaccine preparation and administration
Using two independent patient identifiers before vaccine preparation and administration is a standard patient safety practice to prevent wrong-patient errors.
Question 6: A 35-year-old pregnant patient in the first trimester requests an influenza vaccine. What is the appropriate risk management response?
- Defer the vaccine until the second trimester to avoid teratogenic risk
- Administer the inactivated influenza vaccine, as it is safe and recommended throughout pregnancy (Correct answer)
- Offer only the live attenuated influenza vaccine as it poses fewer risks in pregnancy
- Withhold the vaccine until after delivery because all vaccines are contraindicated in pregnancy
Correct answer: Administer the inactivated influenza vaccine, as it is safe and recommended throughout pregnancy
Inactivated influenza vaccine is recommended for pregnant women in any trimester; the live attenuated (nasal) form is contraindicated during pregnancy.
Question 7: What is the recommended minimum needle length for IM vaccination in an average adult to ensure intramuscular delivery and reduce injection-site adverse events?
- 5/8 inch (16 mm)
- 1 inch (25 mm) (Correct answer)
- 1½ inches (38 mm)
- 2 inches (50 mm)
Correct answer: 1 inch (25 mm)
ACIP recommends a 1-inch needle for most average-weight adults to reliably reach deltoid muscle and minimize subcutaneous deposition or SIRVA risk.
