INR

Fibrinogen level

Answer and Explanation

The Correct Answer is A

B.   Fibrinogen level measures clotting potential but is not directly related to warfarin therapy monitoring.
C.   Activated Partial Thromboplastin Time (aPTT) is used to monitor other anticoagulants like heparin, not warfarin.

Correct Answer is D

Explanation

A. Incorrect. Unused medication replacement might not be necessary every 6 months and depends on the expiration date of the medication container.

A. Measure gastric residual volumes every 4 hr. B. Flush the NG tube with 30 mL 0.9% sodium chloride before and after medication. C. Maintain the head of the bed at a 20° angle. D. Advance the rate of the feeding every 2 hr.

Correct Answer is A

Explanation

A. Correct. Measuring gastric residual volumes every 4 hours is important to assess gastric emptying and to determine if the client can tolerate the feedings. If residuals are high, it may indicate delayed gastric emptying and the need to adjust the feeding rate.

B. Incorrect. While flushing the NG tube before and after medications is important to maintain patency, it is typically done with sterile water, not sodium chloride, unless otherwise specified by a protocol. Therefore, this statement may not be fully accurate.

C. Incorrect. The head of the bed should be elevated to a 30-45° angle to help prevent aspiration during enteral feedings.

D. Incorrect. The rate of the feeding should be advanced gradually to prevent overloading the client's gastrointestinal tract. This does not involve advancing the rate every 2 hours.
