Pediatric Clinical Nurse Specialist Exam Questions Questions
Question 1 of 5
In metabolic disorders, which of the following is most likely associated with cerebral edema if improperly treated?
Correct Answer: B
Rationale: Rapid correction of hypernatremia can lead to cerebral edema due to osmotic shifts in brain cells.
Question 2 of 5
The main diagnostic sign of cardiac arrest is
Correct Answer: C
Rationale: Absence of a central pulse (carotid or femoral) confirms cardiac arrest. Peripheral pulses may be weak in shock, but loss of a central pulse requires immediate resuscitation efforts.
Question 3 of 5
Which of the following statements is TRUE regarding hypernatremic dehydration:
Correct Answer: A
Rationale: Hypernatremic dehydration occurs when water loss exceeds sodium loss, leading to increased serum osmolality (>295 mOsm/L) and sodium levels (>145 mEq/L). This can result from inadequate fluid intake, excessive sweating, or osmotic diuresis.
Question 4 of 5
Which of the following is the primary treatment for patent ductus arteriosus (PDA) in a preterm infant?
Correct Answer: B
Rationale: Indomethacin, a nonsteroidal anti-inflammatory drug, is used to help close a patent ductus arteriosus in preterm infants by inhibiting prostaglandins, which are involved in maintaining the ductus open.
Question 5 of 5
A red-haired, blue-eyed, Caucasian 15-year-old with a small congenital nevus undergoes a biopsy to rule out melanoma. For pain control, naproxen 15 mg/kg TID is given. Two days after surgery, blood is noted to be oozing from the wound, which won’t stop bleeding. All of the following are correct EXCEPT
Correct Answer: C
Rationale: Ibuprofen also has anticoagulant properties similar to naproxen, meaning bleeding risk would not be completely avoided by switching to ibuprofen.
