Nursing Elites

1. Why is the specific gravity for infants lower than for older children?

• A. Infants have a greater body surface area.
• B. Infants have a higher basal metabolic rate.
• C. Infants have a greater percentage of body weight that is water.
• D. Infants' kidneys are less able to concentrate urine.

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. When teaching an adolescent about managing tinea pedis, which statement indicates an understanding of the teaching?

• A. I should buy some plastic shoes to wear at the swimming pool
• B. I should wear sandals as much as possible
• C. I should place the permethrin cream between my toes twice daily
• D. I should seal my non-washable shoes in plastic bags for a couple of weeks

Correct answer: B

Rationale: Wearing sandals allows air circulation around the feet, reducing perspiration and eliminating the environment for bacteria and fungus to thrive. This promotes the healing of the fungal infection. Therefore, the correct answer is B.

3. When a patient is taking glucocorticoids and digoxin, which electrolyte should the nurse prioritize monitoring?

• A. Calcium
• B. Magnesium
• C. Sodium
• D. Potassium

Correct answer: D

Rationale: The nurse should primarily monitor potassium levels in a patient taking glucocorticoids and digoxin. Glucocorticoids can lead to potassium loss, potentially increasing the risk of digoxin toxicity. Additionally, glucocorticoids may worsen hypokalemia induced by diuretics like thiazides and loops. While calcium, magnesium, and sodium are important electrolytes to monitor in various clinical situations, they are not the priority in this specific scenario of a patient on glucocorticoids and digoxin.

4. A child is being cared for following a head injury. Which of the following findings should indicate to the healthcare provider that the child is developing diabetes insipidus?

• A. Urine specific gravity of 1.045
• B. Sodium level of 155
• C. Blood glucose level of 45
• D. Urine output of 35 ml per hour

Correct answer: B

Rationale: In a child with a head injury, the development of diabetes insipidus can occur due to pituitary hypofunction, leading to a deficiency of antidiuretic hormone. An elevated sodium level (hypernatremia) is a key finding in diabetes insipidus due to the excessive loss of free water in the urine, resulting in increased sodium concentration in the blood.

5. Which strategy is most likely to promote positive behavior in children?

• A. Providing flexible instructions with no consequences
• B. Limiting opportunities until the child performs adequately
• C. Improving the child's competence and creating a positive environment
• D. Setting strict rules with punishments for misbehavior

Correct answer: C

Rationale: Improving the child's competence and creating a positive environment is the most effective strategy to promote positive behavior in children. This approach focuses on enhancing the child's skills and abilities while fostering a supportive and encouraging atmosphere. By empowering the child and surrounding them with positivity, they are more likely to exhibit positive behaviors as they feel competent, valued, and motivated. This strategy emphasizes support and reinforcement over punitive measures, leading to long-lasting behavioral improvements.
