Correct Answer is B

Explanation

Osmotic laxatives work by drawing water into the intestines, which can lead to fluid loss and dehydration if not enough fluids are consumed.

Oliguria, or decreased urine output, can be a sign of fluid volume deficit and dehydration.

Choice A is wrong because Weight gain, is not an indication of fluid volume deficit as weight loss is more commonly associated with dehydration.

Choice C is wrong because Headaches, can be a symptom of dehydration but is not specific to fluid volume deficit.

Choice D is wrong because Nausea, can also be a symptom of dehydration but is not specific to fluid volume deficit.

A. Document the administration of the medication. B. Identify the client using two identifiers. C. Compare the amount of medication available to the inventory record. D. Remove the medication from the medication dispensing cabinet. E. Remove the medication from the medication dispensing cabinet.

Correct Answer is B

Explanation

The correct answer is Choice B.

Choice A rationale:

Documenting the administration of the medication is crucial for maintaining accurate records and ensuring accountability. However, it is not the first action to take. The priority is to ensure the correct patient receives the correct medication.

Choice B rationale:

Identifying the client using two identifiers is the first and most critical step. This action ensures that the right patient receives the right medication, thereby minimizing the risk of medication errors.

Choice C rationale:

Comparing the amount of medication available to the inventory record is important for maintaining accurate inventory and preventing misuse or theft of controlled substances. However, this is not the first step in the process of administering medication to a patient in pain.

Choice D rationale:

Removing the medication from the medication dispensing cabinet is part of the process, but it should only be done after the patient has been properly identified to avoid any potential errors.
