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. How should the nurse prepare the sibling of a near-drowning accident victim who wants to see his brother in the pediatric intensive care unit, considering the child was present during the accident?

• A. Have the parents explain to the child why the sibling is so sick and inform the child that this could be the last time he sees his brother.
• B. Reassure the sibling not to cry in the child's room to avoid upsetting the ill child.
• C. If death is imminent, avoid informing the child about it and minimize involvement in care to protect the child from further trauma.
• D. Cover tubes and wires with a sheet, wash off any existing blood, and prepare him for what he will see.

Correct answer: D

Rationale: When preparing a sibling to see their brother in the pediatric intensive care unit after a near-drowning accident, it is essential to cover tubes and wires with a sheet, wash off any existing blood, and explain what the sibling will see. This approach helps the sibling understand the situation better and prepares them emotionally for the encounter, reducing potential distress and trauma. By providing information and visual preparation, the sibling can have a more controlled and less overwhelming experience when visiting their brother in the intensive care unit. Choice A is incorrect as informing the child that this could be the last time he sees his sibling may cause unnecessary distress and anxiety. Choice B is incorrect as it dismisses the sibling's emotional response, which is essential to address in a supportive manner. Choice C is incorrect as honesty and appropriate information sharing are crucial, even in difficult situations, to help the child cope effectively with the circumstances.

3. Atta, who weighs 20kg, has been prescribed amoxicillin 500 mg b.i.d. The drug information indicates a daily dose of amoxicillin at 50 mg/kg/day in two divided doses. What is the safest dose in milligrams for this child?

• A. 1000 mg
• B. 750 mg
• C. 500 mg
• D. 250 mg

Correct answer: A

Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.

4. Are most children with hypertension asymptomatic?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is true. In many cases, children with hypertension do not show any symptoms, making it challenging to diagnose them. Regular blood pressure checks are crucial to detect hypertension early, as it can have serious health implications if left untreated. Choice B is incorrect because most children with hypertension do not exhibit symptoms, hence being asymptomatic. Choices C and D are empty as they do not provide additional options.

5. When using the Ballard gestational assessment tool on a newborn, which of the following tests should be performed after the first hour of birth, allowing the newborn to recover from the stress of birth?

• A. Arm recoil
• B. Square window sign
• C. Scarf sign
• D. Popliteal angle

Correct answer: A

Rationale: The correct answer is Arm recoil. Arm recoil is slower in healthy but fatigued newborns after birth, making it best elicited after the first hour of birth when the baby has had time to recover from the stress of birth. This assessment helps evaluate neuromuscular maturity in newborns and is more accurate when performed after the initial recovery period. The other choices, Square window sign, Scarf sign, and Popliteal angle, are not specifically assessed using the Ballard gestational assessment tool and do not relate to the recovery period after birth.
