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. What is the most appropriate nursing action when intermittently gavage feeding a preterm infant?

• A. Allow formula to flow by gravity
• B. Avoid allowing the infant to suck on the tube
• C. Insert the tube through the nares instead of the mouth
• D. Apply gentle pressure to the syringe to deliver the formula

Correct answer: A

Rationale: The correct action when intermittently gavage feeding a preterm infant is to allow the formula to flow by gravity. This method helps prevent overfeeding and aspiration, which can occur if the formula is delivered too quickly under pressure. Choice B is incorrect as sucking on the tube can cause complications. Choice C is incorrect as the tube is typically inserted through the mouth. Choice D is incorrect as steady pressure can lead to rapid delivery of the formula, increasing the risk of complications.

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. Which food should be introduced first to a 6-month-old infant?

• A. Fruits
• B. Eggs
• C. Vegetables
• D. Meat

Correct answer: C

Rationale: Vegetables, particularly pureed ones, are often recommended as a first solid food for infants because they are easy to digest and less likely to cause allergies. Fruits can be introduced later due to their natural sweetness, while eggs and meat are typically introduced after fruits and vegetables as they may pose a higher risk of allergies.

5. A nurse must do a venipuncture on a 6-year-old child. What consideration is important in providing atraumatic care?

• A. Use an 18-gauge needle if possible.
• B. Show the child the equipment to be used before the procedure.
• C. If not successful after four attempts, have another nurse try.
• D. Restrain the child completely.

Correct answer: B

Rationale: Showing the child the equipment before the procedure helps build trust and reduces fear. Using an 18-gauge needle is too large for a child, and multiple attempts can increase trauma. Restraining completely can increase fear and anxiety.
