, A patient with chronic obstructive pulmonary disease (COPD) is admitted
with exacerbation. Which oxygen delivery method is most appropriate to
maintain their oxygen saturation at 88-92%?
A) Non-rebreather mask at 15 L/min
B) Nasal cannula at 2 L/min
C) High flow nasal cannula
D) Mechanical ventilation Answer: B) Nasal cannula at 2 L/min Rationale:
Patients with COPD are at risk of CO2 retention; low flow oxygen (1-2
L/min) helps maintain target saturation without suppressing their
respiratory drive.
Which electrolyte imbalance is of greatest concern in a post-
thyroidectomy patient?
A) Hyperkalemia
B) Hypercalcemia
C) Hypocalcemia
D) Hyponatremia Answer: C) Hypocalcemia Rationale: Removal or
damage to parathyroid glands during thyroidectomy can cause decreased
calcium levels, risking tetany and cardiac arrhythmias.
In managing a patient with acute pancreatitis, which intervention is
priority?
A) Administering opioid analgesics
B) Starting enteral feeding immediately
C) Providing aggressive IV fluid resuscitation
D) Beginning insulin therapy Answer: C) Providing aggressive IV fluid
resuscitation Rationale: Hypovolemia is common due to third spacing,
and fluid resuscitation improves organ perfusion and reduces
complications.

should nurse anticipate administering?
