A patient is receiving an IV infusion of heparin and was started on warfarin therapy the night
- A. Which statement is most correct?
- B. The patient is receiving a double dose of anticoagulants.
- C. The heparin therapy was ineffective, so the warfarin was starte
- D. The heparin provides anticoagulation until therapeutic levels of warfarin are reache
Correct Answer: D
Rationale: The correct statement is that the heparin provides anticoagulation until therapeutic levels of warfarin are reached. Heparin and warfarin are both anticoagulants but work in different ways. Heparin acts quickly to prevent blood clot formation while warfarin takes several days to reach its full effect. Therefore, heparin is often used initially to provide immediate anticoagulation while waiting for the warfarin to reach therapeutic levels. This dual therapy is common in clinical practice to ensure continuous anticoagulation.

- A. Daily weight
- B. Intake and output

A patient requires a nonopioid medication. The nurse knows that which medication will cause the least gastrointestinal distress?
- A. Aspirin
- B. Ketorolac
- C. Celecoxib
- D. Ibuprofen
Correct Answer: C
Rationale: Celecoxib is a selective COX-2 inhibitor, which means it primarily targets the COX-2 enzyme involved in inflammation and pain while sparing the COX-1 enzyme that protects the stomach lining. This selectivity reduces the risk of gastrointestinal distress, such as ulcers and bleeding, compared to non-selective NSAIDs like aspirin, ketorolac, and ibuprofen. Therefore, celecoxib is the best choice for patients who require a nonopioid medication with minimal gastrointestinal side effects. Nurses should consider this when selecting pain management options for patients with a history of gastrointestinal issues.
The nurse notes in the patient™s medication orders that the patient will be taking ibutilide (Corvert). Based on this finding, the nurse interprets that the patient has which disorder?
- A. Ventricular ectopy
- B. Atrial fibrillation
- C. Supraventricular tachycardia
- D. Bradycardia
Correct Answer: B
Rationale: Ibutilide (Corvert) is a medication commonly used to treat atrial fibrillation, a type of irregular heart rhythm that originates in the heart's upper chambers (atria). It works by restoring normal heart rhythm in patients with atrial fibrillation. Therefore, the nurse notes the use of ibutilide in the patient's medication orders, indicating that the patient has atrial fibrillation.
