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. The Andrews family has been taking good care of their youngest, Archie, who was diagnosed with asthma. Which of the following statements indicate a need for further home care teaching?

• A. He should increase his fluid intake regularly to thin secretions.
• B. We'll make sure he avoids exercise to prevent attacks.
• C. He is to use his bronchodilator inhaler before the steroid inhaler.
• D. We need to identify what triggers his attacks.

Correct answer: B

Rationale: The correct answer is B. Avoiding exercise entirely is not recommended for asthma management. Regular exercise can actually help strengthen the lungs and improve overall respiratory function. Teaching should focus on appropriate exercise routines that are suitable for individuals with asthma to prevent attacks. Choices A, C, and D are all appropriate and indicate good understanding of asthma management. Increasing fluid intake helps thin secretions, using the bronchodilator inhaler before the steroid inhaler follows the correct order of inhaler administration, and identifying triggers is essential for asthma control.

3. Which behavior is most indicative that a 2-year-old is experiencing the initial phase of separation anxiety because his parents cannot stay all day at the hospital with him?

• A. He withdraws from the nursing staff.
• B. He cries when his parents leave.
• C. He lies quietly in bed.
• D. He cries when his parents arrive.

Correct answer: B

Rationale: The most indicative behavior of a 2-year-old experiencing the initial phase of separation anxiety due to parents not staying all day at the hospital is crying when his parents leave. This behavior is a common manifestation of separation anxiety in children, as they struggle with the absence of their primary attachment figures. Choices A, C, and D are less indicative because withdrawing from the nursing staff, lying quietly in bed, or crying when parents arrive do not specifically demonstrate the distress caused by separation from parents, which is the hallmark of separation anxiety in children.

4. Seizures in children MOST often result from:

• A. a life-threatening infection.
• B. an inflammatory process in the brain.
• C. an abrupt rise in body temperature.
• D. a temperature greater than 102°F.

Correct answer: C

Rationale: Seizures in children most often result from febrile seizures, which are triggered by an abrupt rise in body temperature. Febrile seizures are common in young children, especially between the ages of 6 months to 5 years, and are usually associated with viral infections that cause a sudden spike in body temperature. Choices A, B, and D are incorrect because while infections, inflammatory processes, and high temperatures can sometimes lead to seizures, the most common cause of seizures in children is an abrupt increase in body temperature, known as febrile seizures.

5. When assisting ventilations in a 4-year-old child with a bag-valve mask, what should the EMT do?

• A. Deliver each breath over 2 to 3 seconds.
• B. Ensure the appropriate mask size is used.
• C. Block the pop-off valve if needed to achieve adequate chest rise.
• D. Reassess the pulse rate after 60 seconds.

Correct answer: C

Rationale: When assisting ventilations in a 4-year-old child with a bag-valve mask, the EMT should block the pop-off valve if needed to achieve adequate chest rise. This action helps ensure effective ventilation and adequate oxygenation in the child. Blocking the pop-off valve allows for better control over the volume of air delivered and can help maintain positive pressure in the airway, assisting in improving oxygenation and ventilation in the child. Choices A, B, and D are incorrect because delivering each breath over 2 to 3 seconds is a general guideline but may need adjustment based on patient response, ensuring the appropriate mask size is important but not the primary concern in this scenario, and reassessing the pulse rate is not directly related to the ventilation technique being discussed.
