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. Which of the following are not infectious causes of diarrhea?

• A. Allergy
• B. Bacteria
• C. Parasite
• D. Virus

Correct answer: A

Rationale: Diarrhea can be caused by various infectious agents such as bacteria, parasites, and viruses. Allergy, on the other hand, is a non-infectious cause of diarrhea. When an individual with a food allergy consumes the specific food they are allergic to, it can trigger diarrhea as a part of the allergic reaction.

3. Your assessment of a newborn reveals cyanosis to the chest and face and a heart rate of 90 beats/min. What should you do first?

• A. Dry the infant briskly.
• B. Suction the mouth.
• C. Begin artificial ventilations.
• D. Begin chest compressions.

Correct answer: C

Rationale: In a newborn with cyanosis to the chest and face and a heart rate of 90 beats/min, the priority action is to begin artificial ventilations. A heart rate below 100 beats/min with cyanosis indicates a need for immediate respiratory support to improve oxygenation. Drying the infant briskly or suctioning the mouth may be necessary later but are not the initial priority. Chest compressions are not indicated as the heart rate is above 60 beats/min.

4. The healthcare provider is caring for a newborn who is 2 days old. Which finding should be reported to the healthcare provider?

• A. Yellowing of the skin
• B. Presence of a small amount of blood in the diaper
• C. Peeling skin on the hands and feet
• D. Intermittent episodes of sneezing

Correct answer: A

Rationale: Yellowing of the skin may indicate jaundice in a newborn, which can be a sign of an underlying health issue such as an elevated bilirubin level. It is essential to report this finding to the healthcare provider for further assessment and appropriate management to prevent complications.

5. What is the reason for Asthma in 4-year-old Mabele, as Mrs. Joyce Thomson inquires? How would you explain it?

• A. Asthma occurs due to inflammation of the respiratory tract triggered by infections.
• B. An asthmatic attack can occur when the child is exposed to certain allergens, triggering an allergic reaction in the bronchioles that causes bronchial constriction.
• C. An asthmatic attack is a response to the release of inflammatory mediators to epithelial cells, affecting the autonomic neural control of the airway.
• D. Asthma is not an inborn problem; it involves abnormal growth of the bronchial tree causing restriction.

Correct answer: B

Rationale: Asthma in children like Mabele can be triggered by exposure to allergens, leading to an allergic reaction in the bronchioles. This reaction causes constriction of the bronchial tree, resulting in an asthmatic attack. It is essential for caregivers to identify and minimize exposure to these triggers to manage and prevent asthma episodes effectively.
