Nursing Elites

1. 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.

2. A 12-year-old child is injured in a bicycle accident. When considering the possibility of renal trauma, the nurse should consider what factor?

• A. Flank pain rarely occurs in children with renal injuries.
• B. Few nonpenetrating injuries cause renal trauma in children.
• C. Kidneys are immobile, well protected, and rarely injured in children.
• D. The amount of hematuria is not a reliable indicator of the seriousness of renal injury.

Correct answer: D

Rationale: The amount of hematuria is not a reliable indicator of the severity of renal trauma, as even minor injuries can cause significant bleeding, while severe injuries may result in little or no visible blood. Renal trauma should be evaluated through imaging and clinical assessment.

3. Which drug is usually the best choice for patient-controlled analgesia (PCA) for a child in the immediate postoperative period?

• A. Codeine sulfate (Codeine)
• B. Morphine (Roxanol)
• C. Methadone (Dolophine)
• D. Meperidine (Demerol)

Correct answer: B

Rationale: Morphine is the drug of choice for PCA in children because of its efficacy, safety profile, and rapid onset of action for pain management.

4. An adolescent states, “I want to be a doctor or a lawyer when I grow up because I like taking care of people.” Which Eriksonian challenge is the adolescent attempting?

• A. Identity vs. role diffusion
• B. Trust vs. mistrust
• C. Industry vs. inferiority
• D. Autonomy vs. shame and doubt

Correct answer: A

Rationale: The correct answer is A: Identity vs. role diffusion. During adolescence, individuals face the challenge of forming a cohesive sense of self and identity. In this scenario, the adolescent's desire to become a doctor or lawyer reflects the exploration of potential roles and career paths, indicating an attempt to establish a clear identity. Choices B, C, and D are incorrect. Trust vs. mistrust is a challenge experienced in infancy, industry vs. inferiority is relevant to the school-age period, and autonomy vs. shame and doubt is associated with the toddler stage, not adolescence.

5. Which physiological acid-base balance complication would be most important for the nurse to assess in a patient with diarrhea?

• A. High serum pH
• B. Normal serum pH
• C. Metabolic alkalosis
• D. Metabolic acidosis

Correct answer: D

Rationale: The correct answer is metabolic acidosis. Diarrhea can lead to the loss of bicarbonate, causing an imbalance in the acid-base status of the body, specifically resulting in metabolic acidosis. High serum pH (choice A) is incorrect as diarrhea-induced bicarbonate loss would lower pH, not increase it. Normal serum pH (choice B) is not the best answer as diarrhea can disrupt the acid-base balance. Metabolic alkalosis (choice C) is an alkaline state, which is less likely to be caused by diarrhea.
