Nursing Elites

1. 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.

2. A child with acute lymphocytic leukemia (ALL) who is receiving chemotherapy via a subclavian IV infusion has an oral temperature of 103 degrees. In assessing the IV site, the nurse determines that there are no signs of infection at the site. Which intervention is the most important for the nurse to implement?

• A. Obtain a specimen for blood cultures.
• B. Assess the CBC.
• C. Monitor the oral temperature every hour.
• D. Administer acetaminophen as prescribed.

Correct answer: A

Rationale: Obtaining a specimen for blood cultures is crucial in this situation as it helps identify the source of infection, if present, and guide appropriate treatment. This is important in a child with leukemia receiving chemotherapy to prevent potential complications and ensure timely intervention. Assessing the CBC may provide overall information on the child's condition but may not specifically identify a potential infection. Monitoring the oral temperature is important but obtaining blood cultures takes precedence in this scenario. Administering acetaminophen can help reduce fever but does not address the need to identify a possible infection source.

3. The nurse is assessing a 6-month-old infant. Which response requires further evaluation by the nurse?

• A. Has doubled birth weight.
• B. Turns head to locate sound.
• C. Plays peek-a-boo.
• D. Demonstrates startle reflex.

Correct answer: D

Rationale: At 6 months old, the startle reflex should diminish, so its persistence warrants further evaluation by the nurse. Choices A, B, and C are appropriate developmental milestones for a 6-month-old infant. By 6 months, infants typically double their birth weight, exhibit localization of sound by turning their head, and engage in interactive play like peek-a-boo.

4. A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant’s vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?

• A. Irregular palpable pulse
• B. Hyperactive bowel sounds
• C. Underweight for age
• D. Crying without tears

Correct answer: D

Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications. Irregular palpable pulse (Choice A) could indicate a cardiovascular issue but is less immediately life-threatening in this context. Hyperactive bowel sounds (Choice B) are more indicative of gastrointestinal issues rather than a life-threatening complication. Underweight for age (Choice C) may be concerning for growth-related issues but does not directly indicate a life-threatening complication like dehydration does.

5. A child who weighs 25 kg is receiving IV ampicillin at a dose of 300 mg/kg/24 hours in equally divided doses every 4 hours. How many milligrams should the nurse administer to the child for each dose?

• A. 1875 mg
• B. 625 mg
• C. 2000 mg
• D. 1500 mg

Correct answer: A

Rationale: To calculate the correct dose for each administration, you first need to find the total daily dose: 300 mg/kg * 25 kg = 7500 mg/day. Since this total dose is divided into equally divided doses every 4 hours, there are 6 doses in 24 hours. Therefore, 7500 mg ÷ 6 doses = 1250 mg per dose. The nurse should administer 1250 mg every 4 hours, resulting in a total of 1875 mg for each dose in a 24-hour period. Choice A, 1875 mg, is the correct answer. Choice B, 625 mg, is incorrect as it does not consider the total daily dose and the frequency of administration. Choice C, 2000 mg, is incorrect as it is not the calculated dosage based on the given parameters. Choice D, 1500 mg, is also incorrect as it does not reflect the correct dosage calculation for each dose.
