1. Warning signs that indicate dehydration include all EXCEPT:
- A. Poor skin turgor
- B. Increased urine output
- C. Tachycardia
- D. Eager to drink
Correct answer: B
Rationale: The correct answer is B. Increased urine output is not a warning sign of dehydration; it typically decreases with dehydration. Dehydration often presents with poor skin turgor, tachycardia, and an increased sensation of thirst (eager to drink) as the body tries to compensate for fluid loss. Choices A, C, and D are all correct warning signs of dehydration. Poor skin turgor is a result of decreased skin elasticity due to fluid loss. Tachycardia, an elevated heart rate, can be a compensatory mechanism to maintain cardiac output in dehydration. Feeling eager to drink is a common symptom of dehydration as the body attempts to restore fluid balance.
2. 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.
3. During the initial assessment of the newborn, which of the following data would be considered normal?
- A. Chest circumference 31.5 cm, head circumference 33.5 cm
- B. Chest circumference 30 cm, head circumference 29 cm
- C. Chest circumference 38 cm, head circumference 31.5 cm
- D. Chest circumference 32.5 cm, head circumference 36 cm
Correct answer: A
Rationale: The correct answer is A. During the initial assessment of a newborn, the average head circumference at birth is 32 to 37 cm, while the average chest circumference ranges from 30 to 35 cm. Normally, the head's circumference is about 2 cm greater than the chest circumference at birth. Choice A provides measurements of chest circumference 31.5 cm and head circumference 33.5 cm, both falling within the normal range in terms of actual size and relative size. Choices B, C, and D do not align with the typical measurements seen in a healthy newborn. Choice B has both circumferences below the average range, choice C has the chest circumference above the average, and choice D has the head circumference notably higher than the chest circumference, which is not typical for a newborn.
4. You have just delivered a baby girl. Your assessment of the newborn reveals that she has a patent airway, is breathing adequately, and has a heart rate of 130 beats/min. Her face and trunk are pink, but her hands and feet are cyanotic. You have clamped and cut the umbilical cord, but the placenta has not yet delivered. You should:
- A. reassess the newborn every 5 minutes and transport after the placenta delivers.
- B. keep the newborn warm, give oxygen to the mother if needed, and transport.
- C. massage the lower part of the mother's uterus until the placenta delivers.
- D. give the newborn high-flow oxygen via a non-rebreathing mask and transport.
Correct answer: B
Rationale: In this scenario, the appropriate action is to keep the newborn warm, ensure the mother receives oxygen if needed, and prepare for transport. The newborn is showing signs of central cyanosis (hands and feet being cyanotic), which can be due to various reasons, including inadequate oxygenation. Therefore, ensuring warmth and possible oxygen to the mother are important. Additionally, monitoring both the mother and baby during transport is crucial for their well-being.
5. Which of the following signs or symptoms is more common in children than adults following an isolated head injury?
- A. Changes in pupillary reaction
- B. Tachycardia and diaphoresis
- C. Nausea and vomiting
- D. Altered mental status
Correct answer: C
Rationale: Nausea and vomiting are more common in children than adults following an isolated head injury. Children often present with gastrointestinal symptoms like nausea and vomiting after a head injury due to differences in physiological responses compared to adults.
