1. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

2. In growing children, growth hormone deficiency results in short stature and very slow growth rates. Short stature may result from which of the following?

• A. Anterior pituitary gland hypofunction
• B. Posterior pituitary gland hyperfunction
• C. Parathyroid gland hyperfunction
• D. Thyroid gland hyperfunction

Correct answer: A

Rationale: Short stature in growing children can result from anterior pituitary gland hypofunction, which leads to growth hormone deficiency. The anterior pituitary gland plays a crucial role in stimulating the release of growth hormone, and when it is underactive (hypofunction), insufficient growth hormone is produced, resulting in short stature and slow growth rates.

3. When does the rash in typhoid fever typically appear?

• A. On the second day after symptoms appear
• B. On the third day after symptoms appear
• C. On the fourth day after symptoms appear
• D. On the seventh day after symptoms appear

Correct answer: B

Rationale: In typhoid fever, the rash typically appears on the third day after symptoms first appear. This rash can help in diagnosing the disease along with other symptoms such as fever, malaise, and abdominal pain. Choices A, C, and D are incorrect because the rash in typhoid fever usually appears on the third day, not the second, fourth, or seventh day after the symptoms begin.

4. After the baby's head delivers, how is it usually tilted?

• A. with the face up.
• B. anteriorly, with the chin up.
• C. posteriorly, to one side.
• D. posteriorly, face down.

Correct answer: C

Rationale: After the baby's head delivers, it is typically tilted posteriorly to one side to help facilitate the delivery of the shoulders. This positioning is important for the safe and smooth delivery of the baby.

5. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.
