How Much You Know About Pharyngitis? Quiz

Streptococcal pharyngitis is less common in infants because

Not part of flora yet
Strep. pneumo is more virulent
IgG protection from mother
Decreased exposure to other children

Correct Answer

A. IgG protection from mother

Explanation

Infants are less likely to develop streptococcal pharyngitis because they receive passive immunity from their mother through the transfer of IgG antibodies. These antibodies provide protection against the streptococcal bacteria, reducing the risk of infection. As infants have not yet developed their own immune system and their flora is not fully established, the transfer of maternal antibodies helps to protect them from various infections, including streptococcal pharyngitis.

Grisel Syndrome is associated with

Glomerlular nephritis
AA subluxation
Calcified Mitral valve
Bilateral PTA

Correct Answer

A. AA subluxation

Explanation

Grisel Syndrome is a rare condition characterized by atlantoaxial subluxation, which is the displacement of the first and second cervical vertebrae. This condition typically occurs following an infection or inflammation in the upper respiratory tract, leading to ligament laxity and instability in the neck. As a result, the atlantoaxial joint becomes misaligned, causing subluxation. This can lead to compression of the spinal cord and neurological symptoms. Therefore, the correct answer is AA subluxation.

A ten-year-old female presents with severe throat pain and grey-black pseudo-membranous pharyngitis, what is the expected organism.

Gram positive bacilli
Gram positive cocci
Gram positive pseudo-spores in chains
Gram positive rods

Correct Answer

A. Gram positive rods

Explanation

The presence of severe throat pain and grey-black pseudo-membranous pharyngitis suggests a case of diphtheria, which is caused by the bacterium Corynebacterium diphtheriae. C. diphtheriae is a Gram-positive rod-shaped bacterium, hence the correct answer is Gram positive rods.

The best choice for the paroxysmal stage of pertussis is

Cephalosporin
Penicillin derivatives
Macrolides
Oral codeine

Correct Answer

A. Oral codeine

Explanation

Oral codeine is the best choice for the paroxysmal stage of pertussis because it helps to suppress coughing and provide relief from symptoms. Codeine is an opioid that acts on the cough center in the brain, reducing the frequency and intensity of coughing spells. It is effective in controlling the severe coughing fits that are characteristic of the paroxysmal stage of pertussis. Other options like cephalosporin, penicillin derivatives, and macrolides may be used in other stages of pertussis or for treating the underlying bacterial infection, but they do not directly address the coughing symptoms.

A 3 to 5 mm Mitsuda reaction is associated with

Tuberculoid Leprosy
Lepromatous Leprosy
Intermediate
Strongly Positive reaction

Correct Answer

A. Intermediate

Explanation

A 3 to 5 mm Mitsuda reaction is associated with an Intermediate reaction. This means that there is a moderate immune response to the tuberculoid leprosy bacteria.

All of the following medications are associated with SJS except

Sulfonamide
Anti-convulsants
Barbiturates
Antivirals

Correct Answer

A. Antivirals

Explanation

SJS, or Stevens-Johnson syndrome, is a severe and potentially life-threatening skin condition. It is commonly associated with certain medications, including sulfonamide antibiotics, anti-convulsants, and barbiturates. However, antivirals are not typically associated with SJS. Therefore, the correct answer is antivirals.

Nikolsky sign is most often seen on mucosal surfaces.

True
False

Correct Answer

A. False

Explanation

The Nikolsky sign is a clinical sign characterized by the detachment of the epidermis upon gentle pressure on the skin. It is most commonly associated with certain blistering skin diseases, such as pemphigus vulgaris and toxic epidermal necrolysis. While it can occur on mucosal surfaces, it is actually more frequently seen on the skin. Therefore, the statement that the Nikolsky sign is most often seen on mucosal surfaces is false.

What age group does Mono-spot become effective?

5
10
15
>20

Correct Answer

A. 10

Explanation

Mono-spot, also known as the Monospot test, is a diagnostic test used to detect the presence of antibodies that are produced in response to the Epstein-Barr virus (EBV), which causes mononucleosis. This test becomes effective at the age of 10 because it is during this age that most children have been exposed to EBV and have developed antibodies against it. Therefore, the test is more likely to accurately detect the presence of the virus in individuals above the age of 10.
