Nursing Elites

1. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

2. A father calls the clinic because he found his young daughter squirting Visine eyedrops into her mouth. What is the most appropriate nursing action?

• A. Reassure the father that Visine is harmless.
• B. Direct him to seek immediate medical treatment.
• C. Recommend inducing vomiting with ipecac.
• D. Advise him to dilute Visine by giving his daughter several glasses of water to drink.

Correct answer: B

Rationale: Visine is not harmless when ingested, and immediate medical treatment is necessary due to the risk of toxicity. Vomiting should not be induced without medical advice, and dilution with water is not an appropriate treatment.

3. A 14-month-old child is admitted to the hospital with laryngotracheobronchitis (LTB). Which assessment findings should the nurse expect?

• A. Cyanosis and dyspnea
• B. Productive cough and high fever
• C. Barking cough and inspiratory stridor
• D. Pale laryngeal and dyspnea

Correct answer: C

Rationale: The correct answer is C: 'Barking cough and inspiratory stridor.' Classic signs of laryngotracheobronchitis (LTB) include a barking cough, often described as a seal-like cough, and inspiratory stridor, which is a high-pitched sound heard during inspiration. These symptoms occur due to inflammation and narrowing of the upper airway. Choices A, B, and D are incorrect as they do not align with the typical assessment findings of LTB. Cyanosis and dyspnea (Choice A) may occur in severe cases but are not specific to LTB. Productive cough and high fever (Choice B) are more indicative of lower respiratory tract infections. Pale laryngeal and dyspnea (Choice D) are not characteristic findings of LTB.

4. A toddler’s mother calls the nurse because she thinks her son has swallowed a button type of battery. He has no signs of respiratory distress. The nurse’s response should be based on which premise?

• A. An emergency laparotomy is very likely.
• B. The location needs to be confirmed by radiographic examination.
• C. Surgery will be necessary if the battery has not passed in the stool in 48 hours.
• D. Careful observation is essential because an ingested battery cannot be accurately detected.

Correct answer: B

Rationale: Radiographic examination is essential to confirm the location of the battery, as it can cause significant damage, particularly if lodged in the esophagus. Immediate surgery may be required depending on its location and the potential for causing harm.

5. In addition to injuries, what are the leading causes of death in adolescents ages 15 to 19 years?

• A. Suicide and cancer
• B. Suicide and homicide
• C. Drowning and cancer
• D. Homicide and heart disease

Correct answer: B

Rationale: Suicide and homicide are significant causes of death in adolescents, highlighting the need for mental health and violence prevention programs.
