A child is admitted to the emergency room with her mother. Her mother states that she has been exposed to chickenpox. During the assessment, the nurse would note a characteristic rash:

  1. That is covered with vesicular scabs all in the macular stage
  2. That appears profusely on the trunk and sparsely on the extremities
  3. That first appears on the neck and spreads downward
  4. That appears especially on the cheeks, which gives a"slapped-cheek" appearance

Answer(s): B

Explanation:

(A) A rash with vesicular scabs in all stages (macule, papule, vesicle, and crusts). (B) A rash that appears profusely on the trunk and sparsely on the extremities. (C) A rash that first appears on the neck and spreads downward is characteristic of rubeola and rubella. (D) A rash, especially on the cheeks, that gives a "slapped-cheek" appearance is characteristic of roseola.

Which of the following would differentiate acute from chronic respiratory acidosis in the assessment of the trauma client?

  1. Increased PaCO2
  2. Decreased PaO2
  3. Increased HCO3
  4. Decreased base excess

Answer(s): C

Explanation:

(A) Increased CO2 will occur in both acute and chronic respiratory acidosis. (B) Hypoxia does not determine acid-base status. (C) Elevation of HCO3 is a compensatory mechanism in acidosis that occurs almost immediately, but it takes hours to show any effect and days to reach maximum compensation. Renal disease and diuretic therapy may impair the ability of the kidneys to compensate. (D) Base excess is a nonrespiratory contributor to acid-base balance. It would increase to compensate for acidosis.
