1. Why is a prolapsed umbilical cord dangerous?

• A. The cord may be wrapped around the baby's neck, causing strangulation.
• B. The cord might pull the placenta from the uterine wall during delivery.
• C. The baby's head may compress the cord, cutting off its supply of oxygen.
• D. The mother may die of hypoxia due to compromised placental blood flow.

Correct answer: C

Rationale: A prolapsed umbilical cord is dangerous because the baby's head may compress the cord, cutting off its supply of oxygen. This compression can lead to oxygen deprivation, potentially causing significant harm to the baby. Immediate medical intervention is crucial in such cases to prevent adverse outcomes.

2. Justine is admitted to the pediatric unit due to the occurrence of diabetic ketoacidosis signaling a new diagnosis of diabetes. The diabetes team explores the cause of the episode and takes steps to prevent a recurrence. Diabetic ketoacidosis (DKA) results from an excessive accumulation of which of the following?

• A. Sodium bicarbonate from renal compensation
• B. Potassium from cell death
• C. Glucose from carbohydrate metabolism
• D. Ketone bodies from fat metabolism

Correct answer: D

Rationale: Diabetic ketoacidosis (DKA) results from the excessive accumulation of ketone bodies from fat metabolism. During DKA, there is a lack of insulin leading to the breakdown of fat stores into fatty acids and their subsequent conversion into ketone bodies. These ketone bodies accumulate in the blood, leading to metabolic acidosis and the characteristic symptoms of DKA.

3. You are treating a 5-year-old child who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. Supplemental oxygen has been given, and you have elevated his lower extremities. En route to the hospital, you note that his work of breathing has increased. You should:

• A. begin positive-pressure ventilations and reassess the child.
• B. lower the extremities and reassess the child.
• C. listen to the lungs with a stethoscope for abnormal breath sounds.
• D. insert a nasopharyngeal airway and increase the oxygen flow.

Correct answer: B

Rationale: When the work of breathing increases after elevating the legs, it is important to lower the extremities. Elevating the lower extremities in a child with signs of shock can worsen the condition by reducing venous return to the heart. Lowering the extremities can help improve venous return and potentially alleviate the increased work of breathing.

4. The healthcare provider is assessing a newborn who is 2 hours old. Which finding requires immediate intervention?

• A. Acrocyanosis
• B. Respiratory rate of 60 breaths per minute
• C. Grunting with nasal flaring
• D. Heart rate of 140 beats per minute

Correct answer: C

Rationale: Grunting with nasal flaring is a concerning sign of respiratory distress in a newborn that can indicate inadequate oxygenation. This finding requires immediate intervention to ensure the newborn's respiratory status is stabilized and to prevent further complications. Prompt assessment and appropriate intervention are crucial in such cases to prevent respiratory compromise and potential deterioration. Acrocyanosis, which is bluish discoloration of the extremities, is a common finding in newborns and usually resolves on its own. A respiratory rate of 60 breaths per minute and a heart rate of 140 beats per minute are within normal ranges for a newborn and do not indicate immediate intervention is needed.

5. One of the signs of CHF is shortness of breath. What is the term for shortness of breath when lying down?

• A. Platypnea
• B. Orthopnea
• C. Apnea
• D. Epistaxis

Correct answer: B

Rationale: Orthopnea is the specific term used to describe shortness of breath when lying down. This condition is commonly seen in patients with congestive heart failure (CHF) due to the redistribution of fluid in the body when changing positions. Platypnea refers to shortness of breath that worsens when sitting or standing, apnea is the cessation of breathing, and epistaxis is the medical term for a nosebleed. Therefore, the correct answer is B (Orthopnea).
