NNP Practice Exam 3 Questions And 100%
Correct Answers
Cutis aplasia is a congenital anomaly characterized by the presence of which of the
following?
Absence of all or part of the layers of skin
Absence or atrophy of nails
Bullous eruption and peeling of the epidermis - ANSWER Absence of all or part of the
layers of skin
Pustular melanosis is a neonatal lesion that:
Is benign
Highly contagious
Requires antibiotic therapy - ANSWER Is benign
Collections of melanocytes located in the dermis which present at birth as irregular,
bruise-like spots are:
Café au lait spots
Mongolian spots
Pigmented nevi - ANSWER Mongolian spots
Which of the following is a true statement about Harlequin color changes?
*They are an indication of poor or diminished perfusion and require intervention if they
do not resolve within a short period of time
*They are attributed to a temporary imbalance in the autonomic regulatory mechanism
of the cutaneous vessels
*They are more common in large for gestational age infants - ANSWER They are
attributed to a temporary imbalance in the autonomic regulatory mechanism of the
,cutaneous vessels
Eosinophils which are devoid of bacteria are typically found in:
Erythema toxicum neonatorum
Miliaria
Neonatal acne - ANSWER Erythema toxicum neonatorum
White leaf macules are the earliest cutaneous manifestations of:
Addison's disease
Neurofibromatosis
Tuberous sclerosis - ANSWER Tuberous sclerosis
*White leaf macules are the earliest cutaneous manifestations of tuberous sclerosis, an
autosomal dominant syndrome. These macules vary in size and shape but most often
resemble a mountain ash leaflet. They may be difficult to see in a newborn infant and
can best be observed by examination with a Wood lamp. The lamp enhances the
contrast between the macule and normal skin. Normal infants may occasionally have a
single lesion, but the presence of one or more of these macules in an infant with
neurological problems strongly suggests the diagnosis of tuberous sclerosis. A skin
biopsy is not diagnostic. Indurated violet or red plaques or sharply defined
subcutaneous nodules on the buttocks, thighs, trunk, face, or arms are most likely
which of the following?
Intracutaneous hemorrhage
Sclerema
Subcutaneous fat necrosis - ANSWER Subcutaneous fat necrosis
An unusual condition that primarily affects full-term babies, has been related to birth
trauma, shock, asphyxia, hypothermia, convulsions, hypothermia, toxemia of
pregnancy, meconium aspiration and intra-partum medication. One or several
indurated, violet or red plaques or sharply circumscribed subcutaneous nodules on the
buttocks, thighs, trunk, face, or arms may evolve. Most areas are resorbed gradually in
weeks to months if untreated. Residual atrophy or scarring is not common.
Which of the following is present at birth and is most commonly found on the face, the
palms of the hands, and the soles of the feet?
, Infantile acne
Neonatal pustular melanosis
Staphylococcal impetigo - ANSWER Neonatal pustular melanosis
Transient neonatal pustular melanosis may resemble miliaria. It is present at birth, for
which reason the infant is often isolated unnecessarily.
It most commonly occurs on the face, the palms of the hands, and the soles of the feet,
and are most often seen in black infants. If the lesion contents are smeared on a slide
and stained, they are found to be amorphous debris. These lesions are neither
infectious nor contagious, and require no treatment. Which of the following would one
consider in the presence of café au lait spots?
Neurofibromatosis
Niemann-Pick disease
Tuberous sclerosis - ANSWER Neurofibromatosis
Which of the following is correct concerning port-wine stains?
*The birthmark may be a sign of a multisystem disorder
*The birthmark is purple at birth in the full term infant
The most common location of this birthmark is the trunk and lower extremities-ANSWER
The birthmark may be a sign of an illness that involves several systems
Port-wine stain is an angioma composed of dilated and congested capillaries that lie just
beneath the epidermis.
At birth, the mark is pink but darkens to purple over time. It most often occurs on the
face and neck and is a permanent developmental defect. A port-wine stain is primarily a
cosmetic problem although it can be an indicator of a multisystem disorder such as
Sturge-Weber syndrome or Klippel-Trenaunay-Weber syndrome. Gradual thickening
and nodule formation can occur with port-wine stain, thus supporting the need for early
treatment in infancy and childhood. Scalded skin syndrome is caused by:
Serratia
Staphylococcus aureus
