Question 1

A nurse notices a patient's SpO2 drops to 88% while sleeping. What is the most appropriate initial intervention?

Accepted Answer

Apply supplemental oxygen at 2-4 L/min via nasal cannula and reassess

Answer

Initial supplemental oxygen via nasal cannula and reassessment is appropriate for mild hypoxia before escalating interventions.

Question 2

When performing a capillary blood glucose check, which site is preferred for an adult patient?

Accepted Answer

The lateral aspect of the fingertip

Answer

The lateral aspect of the fingertip has fewer nerve endings, causing less pain while still providing an adequate blood sample.

Question 3

A patient is prescribed vancomycin. Which lab value must be monitored to prevent nephrotoxicity?

Accepted Answer

Serum creatinine and BUN

Answer

Vancomycin is nephrotoxic, so serum creatinine and BUN must be monitored to detect renal impairment early.

Question 4

Which assessment finding in a post-operative patient warrants immediate notification of the physician?

Accepted Answer

Urine output of 20 mL over 2 hours

Answer

Urine output less than 30 mL/hour indicates oliguria and potential renal hypoperfusion requiring urgent intervention.

Question 5

A patient with COPD is receiving oxygen therapy. The nurse should titrate oxygen to maintain SpO2 at which target range?

Accepted Answer

88-92%

Answer

COPD patients may rely on hypoxic drive; SpO2 88-92% prevents both hypoxia and suppression of the respiratory drive.
