A client is being treated for chronic kidney disease (CKD). On examination, the client has an elevated blood pressure (BP) and is exhibiting changes in mental status. Which intervention in the plan of care should the practical nurse (PN) implement?

Client's pain rating on a scale of 1 to 10: This information helps assess the client's current pain level and determine the need for pain medication.

Time of the last administration of pain medication: This is important to avoid overdosing or administering pain medication too frequently. It helps ensure that pain medication is given at the appropriate time intervals.

Effectiveness of the last pain medication administered: Understanding whether the previous dose provided relief or not helps guide the choice of the next medication or dosage.

The other options are not directly related to the immediate decision of administering pain medication:

Height and weight of the client prior to admission may be part of the client's medical history but are not typically required information just before administering pain medication.

A history of pain medication use during the past year is important information but may be already documented in the client's medical records and not necessary to obtain immediately before administration.

A. Skipped eating lunch would more likely cause hypoglycemia rather than diabetic ketoacidosis (DKA). When a person with type 1 diabetes skips a meal but still takes insulin, blood glucose levels drop, leading to hypoglycemia, not the elevated glucose and ketone production seen in DKA.

B. Incorrectly administered too much insulin would also result in hypoglycemia rather than DKA. Administering excessive insulin causes blood glucose levels to fall too low, which does not trigger the fat breakdown and ketone production that characterize DKA.

C. Had a cold and ear infection for the past two days is the most likely cause of diabetic ketoacidosis. Illness and infection cause the body to release stress hormones such as cortisol and adrenaline, which increase blood glucose levels and counteract insulin. In type 1 diabetes, insufficient insulin leads to hyperglycemia, fat breakdown for energy, and the production of ketones, resulting in DKA.

D. Ate an extra peanut butter sandwich before gym class would not cause DKA. Consuming extra food may raise blood glucose temporarily, but it would not lead to the severe insulin deficiency and ketone production seen in DKA, especially if the adolescent took insulin as prescribed.
