Which is true of a Wilms tumor? (Select all that apply.)
- A. It is also referred to as neuroblastoma.
- B. It is most commonly seen between the ages of 2 and 5 years.
- C. It can occur on its own or be associated with congenital anomalies.
- D. It is a slow-growing tumor.
Correct Answer: C
Rationale: Wilms tumor typically occurs in children aged 2-5 years and may be associated with congenital anomalies. It is not the same as neuroblastoma, and its prognosis is generally good with treatment.
Bryce is a child diagnosed with coarctation of aorta. While assessing him, Nurse Zach would expect to find which of the following?
- A. Squatting posture
- B. Absent or diminished femoral pulses
- C. Severe cyanosis at birth
- D. Cyanotic ("tet") episodes 46
Correct Answer: B
Rationale: Coarctation of the aorta is a congenital heart defect where there is a narrowing of the aorta, usually near the insertion of the ductus arteriosus. This narrowing can lead to decreased blood flow to the lower body. A common finding in a child with coarctation of the aorta is absent or diminished femoral pulses due to the obstruction of blood flow through the narrowed aorta. Other symptoms may include high blood pressure in the arms, weak lower body pulses, and heart murmur. Squatting posture, severe cyanosis at birth, and cyanotic ("tet") episodes are not typically associated with coarctation of the aorta.
Which describes marasmus?
- A. Deficiency of protein with an adequate supply of calories
- B. Not confined to geographic areas where food supplies are inadequate
- C. Syndrome that results solely from vitamin deficiencies
- D. Characterized by thin, wasted extremities and a prominent abdomen resulting from edema (ascites)
Correct Answer: D
Rationale: Marasmus is a form of severe malnutrition characterized by a deficiency of both calories and protein in the diet. It typically occurs in young children and is often associated with a lack of adequate food intake. The classic presentation of marasmus includes extreme wasting of muscle and fat tissues, resulting in a gaunt appearance with thin limbs and a distended abdomen due to diminished muscle and subcutaneous fat. This differentiates it from kwashiorkor, another form of severe acute malnutrition characterized by edema and a protruding belly but with retained muscle mass. Therefore, option D, characterized by thin, wasted extremities and a prominent abdomen resulting from edema (ascites), accurately describes marasmus.
Which of the ff is the result of central nervous system manifestations?
- A. Congestive Heart Failure c.Valve damage
- B. Chorea
- C. Pericarditis
Correct Answer: B
Rationale: Chorea is the result of central nervous system manifestations. Chorea is a movement disorder characterized by involuntary, brief, random, and irregular muscle movements that are often seen in neurological conditions such as Huntington's disease. The central nervous system is responsible for controlling and coordinating movements, so any dysfunction in the central nervous system can lead to movement disorders like chorea. Therefore, chorea is directly related to central nervous system manifestations, unlike congestive heart failure, valve damage, or pericarditis which are primarily related to cardiovascular issues.
