For the past six hours, a postoperative male client has refused pain medication because he believed that he could "tough it out." When an opioid analgesic is administered, the client has difficulty obtaining a satisfactory level of comfort. Which action is best for the practical nurse (PN) to use in assisting this client to deal with his pain?

The correct answer is choice A. Consecutive evening serum glucose greater than 260 mg/dL.

Choice A rationale:

A consecutive evening serum glucose greater than 260 mg/dL indicates persistent hyperglycemia. Inadequate NPH insulin dosage may lead to consistently high blood glucose levels, which can result in various complications.

Choice B rationale:

The complaint of cold feet and numbness is not a specific indicator of inadequate insulin dosage. Neuropathy and circulation issues can occur with poorly controlled diabetes, but they are not solely indicative of inadequate insulin.

Choice C rationale:

Nausea in the morning, even with the ability to eat breakfast, does not necessarily point to inadequate insulin dosage. It could be due to various factors, including dietary choices or other medical conditions.

Choice D rationale:

The wound on the ankle that starts to drain and becomes painful is not a specific sign of inadequate insulin dosage. Poorly controlled diabetes can lead to delayed wound healing, but it does not necessarily indicate that the current insulin dosage is insufficient.

Choice A rationale:

Crushing the medication and administering it in applesauce might alter its pharmacokinetics, rendering it ineffective or causing it to act too quickly. Sublingual tablets are designed to dissolve under the tongue for rapid absorption into the bloodstream. Crushing the tablet and mixing it with applesauce could change its intended mode of action.

Choice B rationale:

Placing the tablet under the client's tongue is the correct action for a sublingual tablet. Sublingual administration allows the medication to dissolve directly into the bloodstream through the sublingual mucosa, bypassing the digestive system and providing rapid onset of action.

Choice C rationale:

Obtaining a liquid form of the medication might be an option, but it may not always be available. Additionally, some medications are not available in liquid forms, and the liquid form might have a slower onset of action compared to the sublingual route.

Choice D rationale:

Placing the tablet inside the client's cheek is known as the buccal route of administration. While this route is also for oral absorption, sublingual administration is preferred for specific medications designed for rapid absorption.
