Answer to Question 1

4
Rationale:
1. If there is a patent ductus arteriosus (PDA), systemic blood flow will be shunted back into the lungs through the patent ductus from the high-pressure aorta into the lower pressure lungs. This will also result in decreased cardiac output.
2. The presence of a PDA will increase pulmonary blood flow.
3. If there is a PDA, cardiac output will decrease, but pulmonary blood flow will be also be increased.
4. Both increased pulmonary blood flow and decreased cardiac output will result with a PDA.

Answer to Question 2

2
Rationale 1: The normal infant triples his birth weight by one year of age.
Rationale 2: It is expected that the infant would double in weight by five months of age.
Rationale 3: The child should double his birth weight by five months. A child whose weight triples by six months of age has gained weight too rapidly.
Rationale 4: The child should triple his birth weight by one year. This child may not be growing adequately.
Global Rationale:
