Nursing Elites

1. 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.

2. At which age can most infants sit steadily unsupported?

• A. 4 months
• B. 6 months
• C. 8 months
• D. 12 months

Correct answer: C

Rationale: Most infants can sit steadily without support by 8 months, indicating advanced gross motor skill development.

3. What type of dehydration occurs when the electrolyte deficit exceeds the water deficit?

• A. Isotonic dehydration
• B. Hypotonic dehydration
• C. Hypertonic dehydration
• D. Hyperosmotic dehydration

Correct answer: B

Rationale: Hypotonic dehydration occurs when the loss of electrolytes exceeds the loss of water, leading to a decrease in plasma osmolarity. This often occurs when sodium loss is greater than water loss, as in diarrhea or vomiting.

4. According to Erikson’s theory of psychosocial development, the school-age child is in which stage?

• A. Industry vs. inferiority
• B. Autonomy vs. shame and doubt
• C. Identity vs. role diffusion
• D. Trust vs. mistrust

Correct answer: A

Rationale: The correct answer is A: 'Industry vs. inferiority.' According to Erikson’s theory, school-age children (approximately 6-12 years old) are in the stage of industry vs. inferiority. In this stage, children focus on developing a sense of competence and productivity. Choice B, 'Autonomy vs. shame and doubt,' is incorrect as it refers to the stage that occurs during early childhood (1-3 years old). Choice C, 'Identity vs. role diffusion,' pertains to adolescence (12-18 years old). Choice D, 'Trust vs. mistrust,' is related to the stage of infancy (0-1 year old). Therefore, option A is the most appropriate stage for school-age children in Erikson's theory.

5. 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.
