Question 2

The client has been newly diagnosed with late latent syphilis and has been prescribed Benzathine penicillin G, 7.2 million units divided over 1-week intervals for 3 weeks. The pharmacy provides the medication in 1.2 million units/2 mL concentration. The injection will be administered into the ventrogluteal site. (note: the maximum amount that can be inject into one site is 3 mL) How many total injections will the client receive for this prescription? Enter your response using a whole number.

Key units:

7.2 million units divided over 1-week for 3 weeks

1.2 million units per 2 mL

Maximum injection for one site is 3 mL

See answer below

Answer:

1) The client is prescribed 7.2 million units divided into 3 doses.

2) Therefore, each dose consists of 2.4 million units. This means that each weekly dose is 4 mL (1.2 million units/2 mL)

3) Since the maximum amount that can be injected into any one site is 3 mL, the 4 mL should be divided between 2 injections.

4) Therefore, each week, the client receives 2 injections , for a total of 6 injections.
