Correct Answer is B

Explanation

Choice A rationale:

Discarding any partial doses found in the cabinet in the sharps container is not the correct procedure. Partial doses should be wasted in the presence of another nurse.

Choice B rationale:

Verifying that the amounts of each medication counted match the amounts on the inventory record is the correct procedure. This ensures accurate accounting of controlled substances.

Choice C rationale:

Setting aside any controlled substances the nurse plans to give during her shift is not the correct procedure. Medications should be removed from the secure cabinet as needed.

Choice D rationale:

Co-signing any notations of wasting controlled substances on the previous shift is not the correct procedure. Wasting should be witnessed and co-signed at the time it occurs.

A. Vitamin A. B. Vitamin C. C. Vitamin B12. D. Vitamin B.

Correct Answer is A

Explanation

Choice A rationale:

Vitamin A is a fat-soluble vitamin. Clients with acute pancreatitis often have difficulty absorbing fat, including fat-soluble vitamins, so supplementation may be necessary.

Choice B rationale:

Vitamin C is a water-soluble vitamin, not a fat-soluble vitamin.

Choice C rationale:

Vitamin B12 is a water-soluble vitamin, not a fat-soluble vitamin.

Choice D rationale:

Vitamin B is a water-soluble vitamin, not a fat-soluble vitamin.
