RN Nursing Care of Children Online Practice 2019 A
1. The nurse is assessing a 3-year-old African American child whose height and weight are at the 20th percentile on the growth chart. What should the nurse recognize?
- A. The data suggest the child requires nutritional intervention
- B. The NCHS charts are accurate for U.S. African American children
- C. A correction factor is used for nonwhite ethnic groups
- D. No assessment can be made until several measurements are plotted over time
Correct answer: B
Rationale: The NCHS growth charts serve as reference guides for all racial or ethnic groups, including African American children. The 20th percentile for height and weight does not indicate nutritional failure but provides a reference point for ongoing assessment. Choice A is incorrect because being at the 20th percentile does not automatically imply the need for nutritional intervention. Choice C is incorrect as there is no correction factor specifically used for nonwhite ethnic groups in this context. Choice D is incorrect as a single measurement at the 20th percentile can provide valuable information for assessment.
2. Using knowledge of child development, what approach is best when preparing a toddler for a procedure?
- A. Avoid asking the child to make choices.
- B. Plan for a teaching session to last about 20 minutes.
- C. Demonstrate on a doll how the procedure will be done.
- D. Show the necessary equipment without allowing child to handle it.
Correct answer: C
Rationale: Demonstrating on a doll helps the toddler understand what will happen in a non-threatening way, making the procedure less intimidating. Long teaching sessions or avoiding choices can increase anxiety.
3. A child is admitted with renal failure. Which of these findings should the nurse expect?
- A. Decreased BUN
- B. Azotemia and oliguria
- C. Increased glomerular filtration rate (GFR)
- D. Polyuria and elevated creatinine clearance
Correct answer: B
Rationale: Azotemia (elevated BUN and creatinine) and oliguria (reduced urine output) are classic signs of renal failure, indicating impaired kidney function. In renal failure, the kidneys are unable to effectively filter waste products, leading to an increase in BUN and creatinine levels in the blood. Additionally, oliguria occurs due to decreased kidney function. Increased GFR (Choice C) is not expected in renal failure as it signifies improved kidney function, which is not the case in renal failure. Polyuria and elevated creatinine clearance (Choice D) are not typical findings in renal failure. Polyuria is more commonly associated with conditions like diabetes insipidus, while elevated creatinine clearance would indicate increased kidney function, which is contrary to the impaired function seen in renal failure.
4. What clinical manifestation(s) is associated with calcium depletion (hypocalcemia)?
- A. Nausea, vomiting
- B. Weakness, fatigue
- C. Muscle hypotonicity
- D. Neuromuscular irritability
Correct answer: D
Rationale: Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as muscle cramps, tetany, or seizures. Other symptoms like nausea, vomiting, and weakness are less specific and can be related to various conditions.
5. A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?
- A. Assist in the passage of formula through the esophagus
- B. Identify the number of reflux episodes that are occurring
- C. Determine the time it takes for the stomach to empty its contents
- D. Monitor the pH within the stomach
Correct answer: B
Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.
