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 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.

3. 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.

4. The child is admitted to the hospital unit newly diagnosed with retinoblastoma. Which clinical manifestation does the nurse anticipate upon assessment?

• A. A white reflex
• B. Blue-tinged sclerae
• C. A red reflex
• D. Yellow-tinged sclerae

Correct answer: A

Rationale: The correct answer is A: A white reflex. The 'white reflex' or leukocoria is a common sign of retinoblastoma. It occurs when the light reflects off the tumor in the eye, giving the pupil a white appearance instead of the normal red reflex. Blue-tinged sclerae (choice B) and yellow-tinged sclerae (choice D) are not typical manifestations of retinoblastoma. A red reflex (choice C) is the normal reflection seen in the eye when light is shone on it and is not associated with retinoblastoma.

5. The nurse is teaching parents about the effects of media on childhood obesity. The nurse realizes the parents understand the teaching if they make which statements? (Select all that apply.)

• A. Advertising of unhealthy food can increase snacking
• B. Increased screen time may be related to unhealthy sleep
• C. There is a link between the amount of screen time and obesity
• D. All of the above

Correct answer: D

Rationale: Increased screen time is associated with unhealthy habits, such as poor sleep and snacking, which contribute to obesity, but it does not necessarily improve nutrition knowledge.
