Question 1

A 7-year-old patient has acute streptococcal erysipelas involving the eyelids. Which of the following is the best oral medication for this patient?

Accepted Answer

Penicillin V

Answer

Explanation:
Penicillin V is the best oral medication for treating acute streptococcal infections, such as erysipelas. It is effective against Streptococcus bacteria, which is the cause of the condition. Tetracycline and doxycycline are not typically used in children due to potential side effects, and cyclosporine is an immunosuppressant, not an antibiotic.

Question 2

A patient has a mucopurulent discharge from a lesion of the right lower eyelid. Which of the following ophthalmic ointments would be most effective to use if a Gram stain of the discharge reveals predominantly polymorphonuclear leukocytes and Gram-negative organisms?

Accepted Answer

Ciprofloxacin

Answer

Explanation:
Ciprofloxacin is an effective antibiotic against Gram-negative organisms. Given that the Gram stain reveals predominantly polymorphonuclear leukocytes and Gram-negative organisms, ciprofloxacin would be the most appropriate choice for treating the infection.

Question 3

A 78-year-old white female tells you that the vision in her right eye gradually has been worsening for the past 2 months. You find that her best corrected visual acuities are 20/60 OD and 20/20 OS. Ophthalmoscopy and macular OCT reveal hemorrhage due to a subfoveal choroidal neovascular membrane OD. Of the following, which is the best management for this patient's right eye?

Accepted Answer

Intravitreal bevacizumab

Answer

Explanation:
Intravitreal bevacizumab is an anti-VEGF (vascular endothelial growth factor) treatment effective for managing choroidal neovascular membranes, which are associated with conditions like age-related macular degeneration. This treatment helps reduce hemorrhage and neovascularization, thus improving or stabilizing vision.

Question 4

You place a 21-year-old female on oral tetracycline 250 mg po qid for 30 days. This long-term treatment may cause all of the following side effects, except:

Accepted Answer

ototoxicity.

Answer

Explanation:
Long-term treatment with tetracycline can cause side effects such as skin photosensitivity, papilledema, and gastrointestinal distress. However, ototoxicity (damage to the ear leading to hearing loss) is not typically associated with tetracycline.

Question 5

Which 2 of the following are most appropriate in the initial management of an adult male who is experiencing an acute anaphylactic reaction?

Accepted Answer

Administer systemic epinephrine.

Answer

Explanation:
In the initial management of an acute anaphylactic reaction, it is crucial to administer systemic epinephrine, as it is the first-line treatment to counteract the severe allergic response. Additionally, calling 911 ensures that the patient receives prompt medical attention and further necessary treatment.
