Q
53. A toddler with congenital heart disease is seen for a 1-week history of facial and lower-extremity edema accompanied by shortness of breath.

Q
  1. A new mother who is on her fourth day of breastfeeding complains to the nurse practitioner of very sore breasts. The nurse practitioner would:

Q
  1. Café-au-lait spots look like tan-to-light brown stains that have irregular borders. They can be located anywhere on the body. Which of the following is a correct statement?
    A) They are associated with neurofibromatosis or von Recklinghausen’s disease

Café-au-lait spots are caused by an increase in melanin content, often with the presence of giant melanosomes. They have irregular borders and vary in color from light to dark brown. Neurofibromatosis causes tumors to grow in the nervous system, and these tumors commonly cause skin changes that are seen as café-au-lait spots.

43
Q
  1. You are reviewing the bilirubin level on a 3-day-old full-term neonate. You note that it is 10 mg/dL. The infant has a slight yellow color to his skin, mucous membranes, and sclera. The infant is feeding well, is not irritable, and has 8 to 10 wet diapers per day. Which of the following is a true statement?

Q
  1. An infant who does not have a history of reactive airway disease and allergy has both inspiratory and expiratory wheezing accompanied by fever and profuse clear nasal discharge. Which of the following is most likely?
    A) Tracheobronchitis
    B) Bronchiolitis
    C) Croup
    D) A small foreign body that is lodged on the left main bronchus
A

B) Bronchiolitis
Symptoms of tracheo bronchitis include prominent dry, nonproductive cough; later, coughing up phlegm is common. Bronchiolitis is a viral infection caused by RSV that is commonly seen during the winter/spring months in infants and young children. Typical signs/symptoms include fever, inspiratory/expiratory wheezing, with clear drainage. Croup is a viral infection with the classic “barking” cough; the patient may have a runny nose, but typically no fever. When a child swallows a foreign object, choking, wheezing, and shortness of breath may occur, but no fever or clear drainage is present.

D) It is best heard at the base at S2
A

Q
  1. A 44-year-old patient with Down syndrome starts to develop impaired memory and difficulty with his usual daily life routines. He is having problems functioning
    at the job that he has done for the past 10 years. The physical exam and routine labs are all negative. The vital signs are normal. His appetite is normal. The most
