The nurse is preparing to administer warfarin (Coumadin), an oral anticoagulant, to a client diagnosed with a pulmonary embolus. Which data would cause the nurse to question administering the medication?
- A. The client's partial thromboplastin time (PTT) is 38.
- B. The client's international normalized ratio (INR) is 5.
- C. The client's prothrombin time (PT) is 22.
- D. The client's erythrocyte sedimentation rate (ESR) is 10.
Correct Answer: B
Rationale: An INR of 5 (B) is above the therapeutic range (2–3 for pulmonary embolus), indicating excessive anticoagulation and bleeding risk, so warfarin should be questioned. PTT (A) is for heparin, not warfarin. PT (C) alone is not standardized. ESR (D) is irrelevant to anticoagulation.

- A. Arthritis
- B. Asthma
- C. Hypertension
- D. Diabetes
- E. Glaucoma

The unlicensed assistive personnel (UAP) assists the client with a chest tube to ambulate to the bathroom. Which situation warrants immediate intervention from the nurse?
- A. The UAP keeps the chest tube below chest level.
- B. The UAP has the chest tube attached to suction.
- C. The UAP allowed the client out of the bed.
- D. The UAP uses a bedside commode for the client.
Correct Answer: B
Rationale: Suction during ambulation (B) restricts mobility and risks dislodgement, requiring intervention. Below chest level (A), ambulation (C), and commode (D) are appropriate.
The client is getting out of bed and becomes very anxious and has a feeling of impending doom. The nurse thinks the client may be experiencing a pulmonary embolism. Which action should the nurse implement first?

- B. Place the client in high Fowler's position.
- C. Obtain a STAT pulse oximeter reading.
- D. Auscultate the client's lung sounds.
