A nurse is reviewing the medical history of a client who asks about the use of warfarin.
The nurse should identify which of the following findings as a contraindication for the administration of this medication?

The correct answer is C. Increased urinary output indicates that furosemide, a loop diuretic, is effective in reducing fluid retention and edema in clients with heart failure. The other findings are not indicative of furosemide effectiveness and may suggest adverse effects or complications. Decreased BUN level may indicate overhydration or liver dysfunction. Decreased hemoglobin level may indicate anemia or bleeding. Increased weight of 0.91 kg (2 lb) may indicate fluid overload or worsening heart failure.

Answer is: b. Document the client's condition every 15 min.

Explanation: The nurse manager should include the guideline to document the client's condition every 15 minutes while using belt restraints. This is to ensure close monitoring of the client's physical and psychological well-being and to evaluate the ongoing need for restraint use.

Choice a. is wrong because requesting a PRN restraint prescription for clients who are aggressive might not be appropriate. The use of restraints should be based on a thorough assessment of the client's condition and should be the least restrictive method possible.

Choice c. is wrong because attaching the restraint to the bed's side rails poses a safety risk to the client, as the side rails can be lowered accidentally or intentionally, leading to potential injury.

Choice d. is wrong because removing the client's restraint every 4 hours might not be appropriate, as it depends on the client's specific needs, facility policies, and state regulations. The nurse should follow appropriate guidelines for removing restraints and reassess the client's need for continued restraint use.
