Nursing Elites

1. The nurse is reviewing the characteristics of culture. Which statement is correct regarding the development of one's culture?

• A. Learned through language acquisition and socialization.
• B. Genetically determined on the basis of racial background.
• C. A nonspecific phenomenon and is adaptive but unnecessary.
• D. Biologically determined on the basis of physical characteristics.

Correct answer: A

Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.

2. A female patient with atrial fibrillation has the following lab results: Hemoglobin of 11 g/dl, a platelet count of 150,000, an INR of 2.5, and potassium of 2.7 mEq/L. Which result is critical and should be reported to the physician immediately?

• A. Hemoglobin of 11 g/dl
• B. Platelet count of 150,000
• C. INR of 2.5
• D. Potassium of 2.7 mEq/L

Correct answer: D

Rationale: The critical lab result that should be reported to the physician immediately in this case is the potassium level of 2.7 mEq/L. A potassium imbalance, especially in a patient with a history of dysrhythmia like atrial fibrillation, can be life-threatening and lead to cardiac distress. Low potassium levels (hypokalemia) can predispose the patient to dangerous arrhythmias, including worsening atrial fibrillation. Hemoglobin of 11 g/dl, platelet count of 150,000, and an INR of 2.5 are within acceptable ranges and not as immediately concerning as a low potassium level in this clinical context.

3. The nurse reviews the record of a newborn infant and notes that a diagnosis of esophageal atresia with tracheoesophageal fistula is suspected. The nurse expects to note which most likely sign of this condition documented in the record?

• A. Incessant crying
• B. Coughing at nighttime
• C. Choking with feedings
• D. Severe projectile vomiting

Correct answer: C

Rationale: In esophageal atresia and tracheoesophageal fistula, the esophagus ends before it reaches the stomach, forming a blind pouch, and there is an abnormal connection (fistula) with the trachea. Any child who exhibits the '3 Cs'"?coughing and choking with feedings and unexplained cyanosis"?should be suspected to have tracheoesophageal fistula. Option A, 'Incessant crying,' is not a typical sign of esophageal atresia with tracheoesophageal fistula. Option B, 'Coughing at nighttime,' is not a specific sign associated with this condition. Option D, 'Severe projectile vomiting,' is not a common sign of esophageal atresia with tracheoesophageal fistula.

4. A client with asthma has low-pitched wheezes present in the final half of exhalation. One hour later, the client has high-pitched wheezes extending throughout exhalation. This change in assessment indicates to the nurse that the client:

• A. Has increased airway obstruction.
• B. Has improved airway obstruction.
• C. Needs to be suctioned.
• D. Exhibits hyperventilation.

Correct answer: B

Rationale: The change from low-pitched wheezes to high-pitched wheezes indicates a shift from larger to smaller airway obstruction, suggesting increased narrowing of the airways. This change signifies a progression or worsening of the airway obstruction. The absence of evidence of secretions does not support the need for suctioning. Hyperventilation is characterized by rapid and deep breathing, which is not indicated by the information provided in the question.

5. A patient in metabolic alkalosis is admitted to the emergency department, and pulse oximetry indicates that the O2 saturation is 94%. Which action should the nurse take next?

• A. Administer bicarbonate.
• B. Complete a head-to-toe assessment.
• C. Place the patient on high-flow oxygen.
• D. Obtain repeat arterial blood gases (ABGs).

Correct answer: C

Rationale: In a patient with metabolic alkalosis and an O2 saturation of 94%, placing the patient on high-flow oxygen is the correct action. Even though the O2 saturation seems adequate, metabolic alkalosis causes a left shift in the oxyhemoglobin dissociation curve, reducing oxygen delivery to tissues. Therefore, providing high-flow oxygen can help compensate for this. Administering bicarbonate would exacerbate the alkalosis. While completing a head-to-toe assessment and obtaining repeat ABGs are important interventions, the priority in this scenario is to improve oxygen delivery by placing the patient on high-flow oxygen.
