All of the following are useful indicators regarding the severity of Tetralogy of Fallot
- A. Systemic arterial oxygen saturation
- B. Intensity of outflow murmur
- C. Functional class
- D. Right ventricular outflow gradient by echocardiography
Correct Answer: B
Rationale: The intensity of the outflow murmur is not a reliable indicator of the severity of Tetralogy of Fallot.
Which type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?
- A. Neurogenic
- B. Cardiogenic
- C. Hypovolemic
- D. Anaphylactic
Correct Answer: D
Rationale: Anaphylactic shock results from extreme allergy or hypersensitivity to a foreign substance. Neurogenic shock results from loss of neuronal control, such as the interruption of neuronal transmission that occurs from a spinal cord injury. Cardiogenic shock is decreased cardiac output. Hypovolemic shock is a reduction in the size of the vascular compartment, decreasing blood pressure, and low central venous pressure.
Dubowitz criteria to assess gestational age include:
- A. Skin colour
- B. Breast tissue
- C. Popliteal angle
- D. Moro reflex
Correct Answer: B
Rationale: Breast tissue is one of the criteria used in the Dubowitz assessment to estimate gestational age. Skin colour, popliteal angle, and Moro reflex are not part of the Dubowitz criteria.
Can parents hold their child during an echocardiogram procedure?
- A. You will be able to hold your child during the procedure.
- B. Your child can be active during the procedure, but can’t sit in your lap.
- C. Your child must lie quietly; sometimes a mild sedative is administered before the procedure.
- D. The procedure is invasive so your child will be restrained during the echocardiogram.
Correct Answer: C
Rationale: Although an echocardiogram is noninvasive, painless, and associated with no known side effects, it can be stressful for children. The child must lie quietly in the standard echocardiographic positions; crying, nursing, or sitting up often leads to diagnostic errors or omissions. Therefore, infants and young children may need a mild sedative; older children benefit from psychological preparation for the test. The distraction of a video or movie is often helpful.
As part of the treatment for heart failure, the child takes the diuretic furosemide (Lasix). As part of teaching home care, the nurse encourages the family to give the child foods such as bananas, oranges, and leafy vegetables. These foods are recommended because they are high in which nutrient?
- A. Chlorides
- B. Potassium
- C. Sodium
- D. Vitamins
Correct Answer: B
Rationale: Diuretics that work on the proximal and distal renal tubules contribute to increased losses of potassium. The child’s diet should be supplemented with this electrolyte. With this type of diuretic, potassium must be monitored and supplemented as needed.
