ANSWERS
1. A nurse is assessing a client who is 1 day post-operative following abdominal
surgery. Which finding requires immediate intervention?
A. Heart rate of 98 bpm
B. Respiratory rate of 24 breaths/min
C. Temperature of 99.8°F (37.7°C)
D. Oxygen saturation of 89% on room air
Correct Answer: D
Rationale: An SpO2 of 89% indicates hypoxemia and is below the normal range
(95–100%). This could signal early hypoventilation, atelectasis, or pulmonary
embolism. The other findings are slightly elevated but not immediately life-
threatening in a post-op client.

3. A nurse is providing discharge teaching to a client with a new prescription for
warfarin (Coumadin). Which statement by the client indicates a need for further
teaching?
A. "I will avoid eating large amounts of spinach and kale."
B. "I can take ibuprofen for my headaches."
C. "I will get my blood drawn regularly to check my INR."
D. "I should watch for bleeding gums or dark stools."
Correct Answer: B
Rationale: Ibuprofen (NSAID) increases bleeding risk when taken with warfarin.
Clients should use acetaminophen instead. Green leafy vegetables (vitamin K)
should be consistent but not avoided entirely. INR monitoring and bleeding signs are
correct statements.
