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. When is a newborn considered premature?

• A. Weighs less than 6.5 pounds.
• B. Is born to a heroin-addicted mother.
• C. Is born before 37 weeks gestation.
• D. Has meconium in or around its mouth.

Correct answer: C

Rationale: A newborn is considered premature if it is born before 37 weeks gestation. Premature birth increases the risk of various health problems as the baby may not be fully developed. Choice A is incorrect because the weight alone does not determine prematurity. Choice B is incorrect as it refers to a specific situation but not a direct indicator of prematurity. Choice D is incorrect as the presence of meconium does not solely indicate prematurity.

3. A child with type 1 diabetes mellitus is brought to the emergency department by the mother, who states that the child has been complaining of abdominal pain and has been lethargic. Diabetic ketoacidosis is diagnosed. Anticipating the plan of care, the nurse prepares to administer which type of intravenous (IV) infusion?

• A. 5% dextrose infusion
• B. Normal saline infusion
• C. NPH insulin infusion
• D. Potassium infusion

Correct answer: B

Rationale: In the management of diabetic ketoacidosis (DKA), the initial intravenous (IV) fluid of choice is normal saline infusion. Normal saline helps to correct dehydration and electrolyte imbalances commonly seen in DKA patients. It does not contain glucose to prevent worsening hyperglycemia or ketoacidosis. NPH insulin infusion is not the initial treatment for DKA; it is typically used after fluid resuscitation. Potassium infusion may be required in DKA to address electrolyte imbalances, but normal saline is the priority for fluid resuscitation.

4. What assessment finding places a newborn at risk for developing physiologic jaundice?

• A. Cephalohematoma
• B. Mongolian spots
• C. Telangiectatic nevi
• D. Molding

Correct answer: A

Rationale: The correct answer is A, Cephalohematoma. Physiologic jaundice in newborns can occur due to the breakdown of excess red blood cells. A cephalohematoma, a collection of blood caused by ruptured blood vessels between a cranial bone's surface and periosteal membrane, can lead to increased red blood cell breakdown. This increased breakdown can contribute to the development of physiologic jaundice in newborns. Choices B, Mongolian spots, and C, Telangiectatic nevi, are both benign skin conditions and are not directly associated with increased red blood cell breakdown. Choice D, Molding, refers to the shaping of the fetal head during passage through the birth canal and is not related to the development of physiologic jaundice.

5. Which of the following statements regarding the length-based resuscitation tape measure is correct?

• A. The resuscitation tape estimates a child's weight based on his or her height.
• B. It is a reliable tool in children who are less than 5 years of age.
• C. The red end of the tape measure is placed at the top of the child's head.
• D. The tape measure can be used in children who weigh up to 75 pounds.

Correct answer: D

Rationale: The length-based resuscitation tape measure is designed to estimate a child's weight based on their length and can be used for children weighing up to 75 pounds. It is a reliable tool for pediatric weight estimation in emergency situations.
