Nursing Elites

1. What is the major criterion for diagnosing cognitive impairment in a child?

• A. An IQ of 75 or less
• B. Subaverage functioning
• C. An IQ of 70 or less
• D. Onset before 18

Correct answer: C

Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.

2. Which signs/symptoms would be considered classical signs of meningeal irritation?

• A. Positive Kernig sign, diarrhea, and headache
• B. Negative Brudzinski sign, positive Kernig sign, and irritability
• C. Positive Brudzinski sign, positive Kernig sign, and photophobia
• D. Negative Kernig sign, vomiting, and fever

Correct answer: C

Rationale: The correct answer is C: Positive Brudzinski sign, positive Kernig sign, and photophobia are considered classical signs of meningeal irritation. The Kernig sign is positive when the leg is extended at the knee and then raised, resulting in pain and resistance. The Brudzinski sign is positive when flexing the neck causes flexion of the hips and knees due to meningeal irritation. Photophobia, or sensitivity to light, is a common symptom due to meningeal inflammation. Choices A, B, and D are incorrect because they do not include the classic signs associated with meningeal irritation.

3. The nurse is caring for a newborn with a myelomeningocele. Before surgery, what should the nursing interventions include?

• A. Leaving the lesion uncovered and placing the infant supine
• B. Covering the lesion with a sterile, saline-soaked gauze
• C. Applying lotion to the lesion to keep it moist
• D. Covering the lesion with a dry, sterile gauze

Correct answer: B

Rationale: The correct intervention before surgery for a newborn with a myelomeningocele is to cover the lesion with a sterile, saline-soaked gauze. This helps protect the exposed spinal cord and meninges from infection and damage. Choice A is incorrect because leaving the lesion uncovered can increase the risk of infection. Choice C is incorrect because applying lotion can introduce contaminants to the lesion. Choice D is incorrect because covering the lesion with a dry gauze can lead to adherence of the gauze to the wound, causing trauma upon removal and disrupting the healing process.

4. The nurse reports that a client is at risk for a brain attack (stroke) based on which assessment finding?

• A. Nuchal rigidity
• B. Carotid bruit
• C. Jugular vein distention
• D. Palpable cervical lymph node

Correct answer: B

Rationale: The correct answer is B: Carotid bruit. A carotid bruit is a significant risk factor for stroke as it indicates turbulent blood flow due to narrowing of the carotid artery. Nuchal rigidity is associated with meningitis, jugular vein distention can be a sign of heart failure, and palpable cervical lymph nodes may indicate infection, but they are not directly linked to stroke risk.

5. A client is receiving a secondary infusion of erythromycin 1 gram in 100 mL dextrose 5% in water (D5W) to be infused in 45 minutes. How many mL/hour should the nurse program the infusion pump?

• A. 100 mL/hour.
• B. 125 mL/hour.
• C. 133 mL/hour.
• D. 150 mL/hour.

Correct answer: C

Rationale: To infuse 100 mL in 45 minutes, the infusion rate should be set to 133 mL/hour (100 mL / 0.75 hours). This calculation is obtained by dividing the total volume to be infused by the total time for infusion (100 mL / 0.75 hours = 133 mL/hour). Therefore, choice C is the correct answer. Choices A, B, and D are incorrect because they do not accurately calculate the infusion rate required to deliver the medication within the specified time frame.
