Module 1 Flashcards
The Ishihara test is used to detect:
- Color blindness
- Streptococcal colonization
- bone conduction of sound
- the red reflex
Color blindness
Any child with hemihypertrophy and any child with aniridia should also be routinely screened for what condition:
- Tuberous Sclerosis
- Wilm’s tumor
- Turner’s Syndrome
- Neurofibroamatosis
Wilm’s tumor
An important feature of Wilms tumor is the occurrence of associated congenital anomalies including renal abnormalities, such as cryptorchidism, hypospadias, duplication of the collecting system, ambiguous genitalia, hemihypertrophy, aniridia, cardiac abnormalities, and Beckwith-Wiedemann, Denys-Drash, and Perlman syndromes. Wilms tumor occurs with equal frequency in both sexes although males are diagnosed younger. There is a higher frequency in African Americans and a lower frequency in Asians.
Please choose the correct definition for the condition sundowning:
- An acute or chronic irritation of the eyelid
- Acute inflammation of palpebral and bulbar surfaces of the eye
- Downward deviation of the eyes associated with hydrocephalus, intracranial hemorrhage, other pathologic brain conditions, or early sign of cerebral palsy.
- A cyst in the eyelid caused by inflation of the meibomian gland
Sundowning - Downward deviation of the eyes associated with hydrocephalus, intracranial hemorrhage, other pathologic brain conditions, or early sign of cerebral palsy; a sign of increased intracranial pressure when symptoms of lethargy, poor feeding, vomiting, bulging fontanel, or rapidly increasing head circumference are noted.
A 5-year-old child is brought to the clinic with bilateral purulent discharge from both eyes. Physical findings include conjunctival redness, bilateral nasal discharge, and a bulging tympanic membrane in the left ear. Based on the history and physical examination the most common causative organism is:
- Streptococcus pneumoniae
- Nontypeable Haemophilus influenzae
- Adenovirus
- trachomatis
Non-typeable H. influenza remains a common cause of AOM and it is the most common cause of otitis-conjunctivitis syndrome. Treated with Augmentin or Omnicef due to beta-lactamase resistance.

Definition of estropia
An inward deviation of the eye is referred to as esotropia”
Lillie is a 6-month-old girly who develops a persistent cough with progressively worsening paroxysms and cyanosis. She has occasional posttusive emesis and is afebrile. Between coughing spells, her physical examination is normal. At this time, what is the most important question to ask the family regarding Lillie’s medical history?
- Early infant deaths in relatives
- Immunizations
- Family history of reactive airways disease
- Birth weight
Immunizations - This history is highly suggestive of pertussis. The clinical course is divided into three stages:
the catarrhal stage, 2-10 days in duration, characterized by rhinorrhea, lacrimation, and sometimes low-grade fever
the paroxysmal stage, lasting 1-6 weeks, during which there are intermittent episodes of coughing that may terminate with a forced inspiration against a partially closed glottis resulting in a “whoop” or may terminate with vomiting
the convalescent stage, lasting up to 6 months, during which the coughing episodes gradually resolve. Infants with pertussis often do not whoop because of their inability to generate sufficient inspiratory forces. Between episodes of cough, the examination is often normal. Of the choices given, the immunization status is of most importance.
Lillie’s white blood cell count is 32,000/mm3, with 80% lymphocytes and 2% mononuclear cells. What is the most appropriate next step at this time?
- Order a CBC with peripheral smear
- Treat symptomatically with humidifier and honey for the cough
- Repeat the blood count in 24 hours
- Prescribe oral azithromycin
Prescribe oral azithromycin - A high white blood count with a marked lymphocytosis is characteristic of pertussis. Therefore, prescribing a macrolide, specifically azithromycin, is the most appropriate choice. A repeat CBC is not needed to follow the the treatment. Infact, antibiotics do not hasten the resolution of the illness but will decrease spread to other household members. Even so, all household contacts should also be treated prophylactically.
Robin is a 6-year-old male known to have mild intermittent asthma. Hilar lymphadenopathy is noticed on the chest x-ray. Robin and his family live in rural Memphis on a farm with chickens. Tuberculin skin testing is negative and the family denies history of exposure to tuberculosis. You suspect histoplasmosis infection. What is the most likely mode of transmission of the spores?
- Droplet inhalation
- Oral ingestion
- Skin inoculation
- Inhalation
Inhalation
Histoplasma capsulatum is the most common primary systemic mycosis in the Unitied Stated and most often occurs in the Ohio and Mississippi river valleys. The organism grows in moist soil and is facilitated by bird droppings. As in adults, the respiratory tract is the portal of entry for histoplasmosis in essentially all cases in children. Inoculation other than by inhalation is exceedingly rare, and person to person transmission does not occur.
What is the major source of immunity conferred in breast milk?
IgM
IgD
Complement mediated
IgA
IgA
Human milk provides optimal nutrition for the growing infant. It contains lactose and other carbohydrates that are substrates for protective microflora, such a Bifidobacterium and Lactobacillus spp. The major immunoglobulin present in breast milk is secretory IgA, and is available to act at the mucosal surface of the small intestine. Immunity is conferred against many specific enteropathogens and toxins. It also has been shown to inhibit binding of H influenzae and S pneumoniae to pharyngeal cells
Camille is a 6-year-old-girl who is unimmunized and has a fever of 104 F (40 C) with crops of vesicles on the trunk along with scattered scabbed lesions. Which of the following infections is the likely diagnosis?
HHV-6
Scabies
Varicella
Measles
Varicella
Primary varicella infection (chickenpox) is most likely to present with a generalized, pruritic vesicular rash and fever. The typical exanthem appears first on the scalp, face, or trunk. New crops of lesions develop over a 1-7 day period. Progression from vesicle to pustule to crusted scab occurs quickly such that lesions of all stages are present after the first 48 hours#*)
