Question 1

A 67-year-old patient with no chronic medical conditions presents to the pharmacy for an annual influenza vaccine. The patient's record shows they have completed their primary childhood vaccinations but have not received any pneumococcal vaccines. According to the most current ACIP recommendations, which vaccine should the pharmacist also recommend to this patient?

Accepted Answer

Prevnar 20 (PCV20)

Answer

According to the Advisory Committee on Immunization Practices (ACIP), adults 65 years or older who have not previously received a pneumococcal conjugate vaccine (PCV) should receive a single dose of either PCV20 or PCV15. If PCV15 is used, it must be followed by a dose of PPSV23 at least one year later. PCV20 is a single-dose option that completes the recommendation, making it a primary choice. While Shingrix is recommended for adults 50 and older and Tdap boosters are needed every 10 years, the key age-based recommendation for a vaccine-naive 67-year-old is for pneumococcal disease.

Question 2

Which of the following patient scenarios represents an absolute contraindication to the administration of a live attenuated vaccine, such as the Measles, Mumps, and Rubella (MMR) vaccine?

Accepted Answer

A 28-year-old woman who is confirmed to be pregnant.

Answer

Live attenuated vaccines are generally contraindicated in individuals who are severely immunocompromised or pregnant due to a theoretical risk of fetal harm. Breastfeeding is not a contraindication. A severe egg allergy is no longer considered a contraindication for the MMR vaccine. A mild illness is a precaution, not a contraindication, and vaccination can typically proceed.

Question 3

A pharmacist is preparing to administer an intramuscular (IM) inactivated influenza vaccine to a 50-year-old male patient who weighs 275 lbs (125 kg). Which needle length is most appropriate to ensure the vaccine is delivered into the deltoid muscle?

Accepted Answer

1.5 inch

Answer

For an intramuscular injection in the deltoid muscle of an adult male weighing over 260 lbs (118 kg), a 1.5-inch needle is recommended to ensure the vaccine penetrates the subcutaneous fat and reaches the muscle tissue. A 1-inch needle may be too short for this patient, and a 5/8-inch needle is for subcutaneous injections or for IM injections in much smaller adults.

Question 4

A pharmacy's vaccine refrigerator experiences a power failure overnight. In the morning, the digital data logger shows the temperature has been 11°C (51.8°F) for the past 6 hours. The recommended storage temperature is 2°C to 8°C. What is the MOST appropriate initial action for the pharmacist to take?

Accepted Answer

Label the exposed vaccines "DO NOT USE," move them to a stable refrigerator, and contact the vaccine manufacturers for guidance.

Answer

During a temperature excursion, the CDC recommends that potentially affected vaccines be immediately isolated and marked "DO NOT USE" to prevent their administration. The vaccines should not be discarded. The next critical step is to contact the vaccine manufacturers and/or the state or local immunization program to obtain specific guidance on whether the vaccines are still viable, as stability data varies by product and excursion details.

Question 5

A 42-year-old landscaper sustains a deep puncture wound from a garden tool contaminated with soil. He believes he had a tetanus shot about 12 years ago but is unsure and has no records. According to ACIP guidelines for wound management, which course of action is most appropriate?

Accepted Answer

Administer both Tdap vaccine and Tetanus Immune Globulin (TIG).

Answer

For a wound that is not clean and minor in a patient with an unknown or incomplete (<3 doses) tetanus vaccination history, ACIP recommends administering both a tetanus toxoid-containing vaccine (Tdap is preferred) and Tetanus Immune Globulin (TIG). Tdap provides active immunity, while TIG provides immediate passive immunity. Administering only one of the two would be insufficient for this high-risk situation.
