- A. Squatting increases the return of venous blood back to the heart.
- B. Squatting decreases arterial blood flow away from the heart.

Which explanation regarding cardiac catheterization is appropriate for a preschool child?
- A. Postural drainage will be performed every 4 to 6 hours after the test.
- B. It is necessary to be completely “asleep†during the test.
- C. The test is short, usually taking less than 1 hour.
- D. When the procedure is done, you will have to keep your leg straight for at least 4 hours.
Correct Answer: D
Rationale: The child’s leg will have to be maintained in a straight position for approximately 4 hours. Younger children can be held in the parent’s lap with the leg maintained in the correct position. Postural drainage will not be performed unless the child has corresponding pulmonary problems. The child should be sedated to lie still, but being completely asleep is not necessary. The test will vary in length of time from start to finish.

- A. Most defects occur with teratogens in the first 2 weeks post-conception
- B. The urachus becomes the median umbilical ligament
- C. The mesonephric duct becomes the male organs

- A. Over 90% of patients show exercise-induced bronchoconstriction
- B. Hypercapnia is the first physiological disturbance in status asthmaticus
- C. Infants are unresponsive to bronchodilators
- D. Spontaneous cure occurs before adolescence
Correct Answer: D
Rationale: Spontaneous cure before adolescence is a recognized phenomenon in childhood asthma, though not all cases resolve. Other options are incorrect: exercise-induced bronchoconstriction is common but not universal, hypercapnia occurs late in status asthmaticus, and infants do respond to bronchodilators.
Which should the nurse consider when preparing a school-age child and the family for heart surgery?
- A. Unfamiliar equipment should not be shown.
- B. Let the child hear the sounds of an ECG monitor.
- C. Avoid mentioning postoperative discomfort and interventions.
- D. Explain that an endotracheal tube will not be needed if the surgery goes well.
Correct Answer: B
Rationale: The child and family should be exposed to the sights and sounds of the intensive care unit (ICU). All positive, nonfrightening aspects of the environment are emphasized. The child should be shown unfamiliar equipment and its use demonstrated on a doll. Carefully prepare the child for the postoperative experience, including intravenous (IV) lines, incision, and endotracheal tube.
