Nursing Elites

1. A 4-year-old child is admitted to the hospital secondary to dehydration. Laboratory tests indicate a high hemoglobin and hematocrit, and the serum sodium is below normal levels. Which condition does the nurse suspect based on the current data?

• A. Hypernatremia
• B. Metabolic acidosis
• C. Hypotonic dehydration
• D. Isotonic dehydration

Correct answer: C

Rationale: The correct answer is hypotonic dehydration. The combination of high hemoglobin and hematocrit with low serum sodium indicates hypotonic dehydration. In this condition, there is an excess of solutes relative to water, leading to higher red blood cell concentration (elevated hemoglobin and hematocrit) and low serum sodium levels.

2. A child with croup has an increased PCO2, a decreased pH, and a normal HCO3 blood gas value. Which finding does the nurse report to the healthcare provider based on these data?

• A. Uncompensated metabolic alkalosis
• B. Uncompensated metabolic acidosis
• C. Uncompensated respiratory acidosis
• D. Uncompensated respiratory alkalosis

Correct answer: C

Rationale: The blood gas values indicate uncompensated respiratory acidosis. In respiratory acidosis, there is an increased PCO2, decreased pH, and a normal HCO3 level. This condition requires immediate attention to address the underlying respiratory problem causing the acidosis.

3. A healthcare professional is preparing to administer a measles, mumps, and rubella (MMR) vaccine to a 15-month-old child. Which of the following findings is a contraindication to the administration of this vaccine?

• A. Family history of egg allergy
• B. Currently taking antibiotics
• C. History of asthma
• D. Presence of rhinorrhea

Correct answer: B

Rationale: Taking antibiotics is a contraindication to receiving the MMR vaccine because antibiotics can potentially interfere with the effectiveness of the vaccine. It is essential to avoid administering the MMR vaccine while the child is on antibiotics to ensure the vaccine provides the intended protection.

4. What is functional behavior analysis?

• A. Systematic observation of behavior
• B. Standardized assessment
• C. Multiple choice examination
• D. Parent-teacher questionnaire

Correct answer: A

Rationale: Functional behavior analysis involves systematically observing behavior to understand its function and context. It focuses on identifying the antecedents and consequences that maintain or influence behavior. This systematic observation helps in determining patterns, triggers, and maintaining factors of behavior. Standardized assessments (choice B) involve using specific tools or tests to measure a person's performance or behavior but do not focus on observation. Multiple choice examinations (choice C) and parent-teacher questionnaires (choice D) are not synonymous with functional behavior analysis as they do not involve direct observation of behavior for analysis.

5. Which clean-catch urinalysis finding should raise the most concern for a child admitted to an urgent care center to rule out a urinary tract infection?

• A. 2+ white blood cells
• B. 1+ red blood cells
• C. Urine appearance: cloudy
• D. Specific gravity: 1.009

Correct answer: D

Rationale: A specific gravity of 1.009 is low, indicating diluted urine, which can be concerning in the context of a urinary tract infection. Diluted urine may suggest inadequate concentration due to increased fluid intake or impaired kidney function, which are important considerations in the assessment of a possible UTI.
