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. During an otoscopic examination on an infant, in which direction is the pinna pulled?

• A. Up and back
• B. Up and forward
• C. Down and back
• D. Down and forward

Correct answer: C

Rationale: For infants, the pinna is pulled down and back to straighten the ear canal and allow proper visualization of the tympanic membrane during otoscopic examination.

3. The nurse is teaching a parent with a 2-month-old infant who has been diagnosed with colic about ways to relieve colic. Which statement by the parent indicates the need for additional teaching?

• A. I should let my infant cry for at least 30 minutes before I respond.
• B. I will swaddle my infant tightly with a soft blanket.
• C. I should massage my infant's abdomen whenever possible.
• D. I will place my infant in an upright seat after feeding.

Correct answer: A

Rationale: Letting an infant cry for prolonged periods can exacerbate colic and increase the infant's distress. It is better to respond promptly to soothe the baby. Other methods like swaddling, gentle massage, and keeping the infant upright can help relieve colic symptoms.

4. The nurse is caring for a child with an order of Ampicillin 250 mg IV in 30 mL of Normal Saline to infuse over 30 minutes. How many mL/hour should the nurse set the pump?

• A. 60
• B. 30
• C. 120
• D. 15

Correct answer: A

Rationale: The correct setting for the infusion pump should be 60 mL/hour to deliver 30 mL in 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume to be infused (30 mL) by the total time for infusion (30 minutes) and then multiply by 60 to convert minutes to hours. Therefore, 30 mL / 30 minutes * 60 minutes/hour = 60 mL/hour. Choices B, C, and D are incorrect because they do not match the calculation based on the given parameters.

5. What measure of fluid balance status is most useful in a child with acute glomerulonephritis?

• A. Proteinuria
• B. Daily weight
• C. Specific gravity
• D. Intake and output

Correct answer: B

Rationale: Daily weight is the most accurate measure of fluid balance in children with acute glomerulonephritis, as it reflects changes in body fluid status more reliably than other measures like proteinuria or specific gravity.
