Nursing Elites

1. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.

2. 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.

3. The nurse is planning an educational session with a group of school-age children. Which primary task from Erikson’s theory of psychosocial development should be addressed?

• A. Establishing trust in others
• B. Developing a sense of autonomy
• C. Developing a sense of industry
• D. Establishing a sense of identity

Correct answer: C

Rationale: In Erikson’s theory of psychosocial development, school-age children typically focus on developing a sense of industry. This stage, occurring during middle childhood, involves the desire to feel competent and productive in their skills and abilities. Choices A, B, and D are incorrect because establishing trust in others (A) is related to the first stage of Erikson's theory (trust vs. mistrust) which occurs in infancy, developing a sense of autonomy (B) is linked to the second stage (autonomy vs. shame and doubt) which occurs in early childhood, and establishing a sense of identity (D) is associated with the fifth stage (identity vs. role confusion) which occurs in adolescence.

4. Parents of a preschool child ask the nurse, "Should we set rules for our child as part of a discipline plan?" Which is an accurate response by the nurse?

• A. It is best to delay the punishment if a rule is broken.
• B. The child is too young for rules. At this age, unrestricted freedom is best.
• C. It is best to set the rules and reason with the child when the rules are broken.
• D. Set clear and reasonable rules and expect the same behavior regardless of the circumstances.

Correct answer: D

Rationale: Clear and reasonable rules provide structure and help children understand expectations, promoting consistent behavior and discipline.

5. What laboratory finding should the nurse expect in a child with an excess of water?

• A. Decreased hematocrit
• B. High serum osmolality
• C. High urine specific gravity
• D. Increased blood urea nitrogen (BUN)

Correct answer: A

Rationale: Water excess typically leads to hemodilution, resulting in a decreased hematocrit. High serum osmolality and specific gravity would indicate dehydration, while elevated BUN could suggest renal impairment or dehydration, not fluid overload.
