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:
Answer(s): B
(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?
Answer(s): C
(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.
When assessing fetal heart rate status during labor, the monitor displays late decelerations with tachycardia and decreasing variability. What action should the nurse take?
Answer(s): D
(A) This is not a normal occurrence. Late decelerations need prompt intervention for immediate infant recovery. (B) To increase O2 perfusion to the unborn infant, the mother should be placed on her left side. (C) IV fluids should be increased, not decreased. (D) Immediate action is warranted, such as reporting findings, turning mother on left side, administering O2, discontinuing oxytocin (Pitocin), assessing maternal blood pressure and the labor process, preparing for immediate cesarean delivery, and explaining plan of action to client.

George Commented on September 26, 2025 I cleared the NCLEX-RN with help from Free-Braindumps.com exam questions. Their free questions felt close to the real exam and gave me solid view. Reviewing rationales daily improved my understanding. Stay consistent, focus on concepts, and you’ll build the confidence to pass. The exam is really hard. So don't take it easy. Portugal
