Nursing Elites

1. When a father asks why his child with tetralogy of Fallot seems to favor a squatting position, the nurse would explain that squatting:

• A. Increases peripheral vascular resistance
• B. Decreases arterial blood flow away from the heart
• C. It's a common resting position when a child is tachycardic
• D. Increases the workload of the heart

Correct answer: A

Rationale: Squatting increases systemic vascular resistance, which leads to a reduction in the right-to-left shunting of blood in children with tetralogy of Fallot. This helps improve oxygenation by balancing the pulmonary and systemic blood flow. The squatting position decreases the pressure in the right ventricle and reduces the magnitude of the right-to-left shunt by increasing afterload, thereby improving oxygenation. Choices B, C, and D are incorrect because squatting does not decrease arterial blood flow away from the heart, is not related to being tachycardic, and does not increase the workload of the heart.

2. Kobby, who is diagnosed with diabetes mellitus type 1, displays symptoms of hypoglycemia; which of the following actions should the nurse instruct the parents to take?

• A. Give the child honey (simple sugar)
• B. Give the child milk (complex sugar)
• C. Contact the healthcare provider before doing anything
• D. Give the child nothing by mouth

Correct answer: A

Rationale: During hypoglycemia, it is crucial to quickly raise blood glucose levels. Giving a simple sugar like honey is recommended as it can rapidly increase blood sugar levels and alleviate the symptoms of hypoglycemia in individuals with diabetes mellitus type 1. Milk, being a complex sugar, will not act as quickly as honey in raising blood sugar levels. Contacting the healthcare provider may lead to a delay in treatment, as immediate action is necessary during hypoglycemia. Withholding food or drink (choice D) is not appropriate when dealing with hypoglycemia as it can worsen the condition.

3. Which of the following is MOST likely to occur in conjunction with a breech presentation?

• A. Vertex presentation
• B. Maternal hypertension
• C. Prolapsed umbilical cord
• D. Premature rupture of the amniotic sac

Correct answer: C

Rationale: In a breech presentation, where the baby's buttocks or feet present first, there is an increased risk of the umbilical cord slipping down alongside or below the presenting part, leading to a prolapsed umbilical cord. This is a serious complication that can compromise fetal blood flow and oxygenation, necessitating prompt intervention to prevent adverse outcomes. Choices A, B, and D are less likely to occur in conjunction with a breech presentation. Vertex presentation is the normal head-first presentation, maternal hypertension is a separate condition that may not be directly related to fetal presentation, and premature rupture of the amniotic sac can happen independently of the baby's presentation.

4. Which of the following are classical clinical manifestations that a patient with diabetes mellitus will exhibit EXCEPT?

• A. Polyuria
• B. Polydipsia
• C. Diabetic Ketoacidosis
• D. Weight loss

Correct answer: C

Rationale: The classical clinical manifestations of diabetes mellitus include polyuria (increased urination), polydipsia (excessive thirst), and weight loss. Diabetic ketoacidosis is not a classical manifestation but rather a serious complication that can occur in individuals with uncontrolled diabetes.

5. When drawing blood from the diabetic patient for a glycosylated hemoglobin (HBA1c) test, the nurse explains to the woman that the test is used to determine:

• A. The highest glucose level in the past week.
• B. Her insulin levels.
• C. Glucose levels over the past three months.
• D. Her usual fasting glucose level.

Correct answer: C

Rationale: The glycosylated hemoglobin (HBA1c) test reflects the average blood sugar levels over the past three months. It provides a more comprehensive view of the individual's glucose control compared to a single point-in-time measurement like a fasting glucose level or the highest glucose level in the past week. Choice A is incorrect because it focuses on a single high glucose level rather than the overall control over a period. Choice B is incorrect as HBA1c is not a test for insulin levels. Choice D is incorrect as the HBA1c test does not reflect a single fasting glucose level but rather an average over a more extended period.
