Nursing Elites

1. A 10-year-old child is admitted with diabetic ketoacidosis (DKA). Which laboratory value should the practical nurse (PN) anticipate?

• A. Elevated blood glucose.
• B. Decreased serum ketones.
• C. Low urine glucose.
• D. High bicarbonate levels.

Correct answer: A

Rationale: In a case of diabetic ketoacidosis (DKA), the primary feature is elevated blood glucose levels due to insulin deficiency. Additionally, ketones are increased in the blood and urine. Bicarbonate levels are usually low because of the metabolic acidosis that accompanies DKA. Therefore, the practical nurse should anticipate elevated blood glucose levels as a characteristic laboratory finding in a child admitted with DKA. Choice B is incorrect because serum ketones are increased in DKA. Choice C is incorrect because in DKA, urine glucose is typically high due to spillage of glucose into the urine. Choice D is incorrect because bicarbonate levels are usually low in DKA, not high.

2. The child is 3 years old and is 2 hours postop from a cardiac catheterization via the right femoral artery. Which assessment finding indicates arterial obstruction?

• A. Blood pressure is decreasing, and the pulse is rapid and irregular.
• B. The right foot feels cool to the touch and appears pale and blanched.
• C. The pulse distal to the femoral artery is weaker in the left foot than the right foot.
• D. The pressure dressing at the right femoral area is damp and oozing blood.

Correct answer: B

Rationale: A cool, pale, and blanched foot is indicative of arterial obstruction, leading to poor blood flow. This finding requires immediate intervention to prevent further complications such as tissue damage or necrosis. Monitoring for signs of arterial compromise, such as color changes, temperature, and capillary refill, is crucial in detecting and managing vascular complications post-cardiac catheterization. Choices A, C, and D do not directly indicate arterial obstruction. While a decreasing blood pressure and rapid, irregular pulse may suggest compromise, these findings are more nonspecific. A weaker pulse distal to the femoral artery indicates reduced perfusion but not necessarily arterial obstruction. Finally, a damp, oozing pressure dressing suggests a dressing issue rather than arterial obstruction.

3. When caring for a child experiencing severe asthma symptoms, which medication should the practical nurse anticipate being administered first?

• A. Inhaled corticosteroids.
• B. Oral corticosteroids.
• C. Short-acting beta agonists.
• D. Leukotriene receptor antagonists.

Correct answer: C

Rationale: In the management of acute asthma exacerbations, the first-line medication for quick relief of bronchoconstriction is a short-acting beta agonist, such as albuterol. These medications help to rapidly open up the airways, providing immediate relief to the patient. Inhaled corticosteroids are more commonly used for long-term control of asthma symptoms, while oral corticosteroids and leukotriene receptor antagonists are often reserved for more severe or chronic cases. Therefore, in a child experiencing severe asthma symptoms, the practical nurse should anticipate the administration of short-acting beta agonists as the initial intervention to provide quick relief and improve breathing.

4. Which statement by a school-aged client going to summer camp indicates the best understanding of the mode of transmission of Lyme disease?

• A. I'll cover my mouth with a wet cloth if there's too much dust blowing.
• B. Cuts and scrapes need to be washed out and covered right away.
• C. I'm not going to swim where the water is standing still or feels too hot.
• D. I have to wear long sleeves and pants when we're hiking around the pond.

Correct answer: D

Rationale: The correct answer is D. Wearing long sleeves and pants helps prevent tick bites, which can transmit Lyme disease. Ticks carrying Lyme disease are often found in wooded or grassy areas, so covering exposed skin can reduce the risk of being bitten by an infected tick. Choices A, B, and C do not address the specific mode of transmission of Lyme disease through tick bites, making them incorrect.

5. A child who is admitted to the hospital with anemia is anxious, fearful, and hyperventilating. The nurse anticipates the child developing which acid-base imbalance?

• A. Metabolic acidosis
• B. Respiratory acidosis
• C. Respiratory alkalosis
• D. Metabolic alkalosis

Correct answer: C

Rationale: In this scenario, the child is hyperventilating, which leads to excessive loss of carbon dioxide. This loss of carbon dioxide causes respiratory alkalosis due to a decrease in the partial pressure of carbon dioxide in the blood. Therefore, the correct answer is respiratory alkalosis. Choices A, B, and D are incorrect. Metabolic acidosis is characterized by a decrease in pH and bicarbonate levels due to conditions like kidney disease. Respiratory acidosis is caused by retention of carbon dioxide, leading to an increase in the partial pressure of carbon dioxide. Metabolic alkalosis results from a loss of acid or an increase in bicarbonate levels.
