An older adult client with a long history of chronic obstructive pulmonary disease (COPD) is admitted with progressive shortness of breath and a persistent cough. The client is anxious and is complaining of a dry mouth. Which intervention should the nurse implement?

A. Measure pulse and blood pressure:
This action is crucial to assess the client's cardiovascular status. Weakness and jitteriness can be related to changes in blood pressure or cardiac function. Measuring pulse and blood pressure helps determine the client's hemodynamic stability.

B. Document anxiety on the surgical checklist:
While anxiety is a valid consideration, addressing the physiological aspects of the client's symptoms takes precedence.

C. Assess skin temperature and moisture:
Assessing skin temperature and moisture provides information about the client's perfusion and hydration status. Changes in skin characteristics can be indicative of underlying issues, and in a diabetic patient, it's important to monitor for potential complications affecting skin integrity.

D. Check fingerstick glucose level:
Given the client's recent diagnosis of type 2 diabetes mellitus and the reported symptoms of weakness and jitteriness, checking the fingerstick glucose level is crucial. Fluctuations in blood glucose levels, whether hyperglycemia or hypoglycemia, can contribute to these symptoms. This test provides immediate information about the client's glycemic status.

E. Administer a PRN dose of regular insulin:
If the fingerstick glucose level indicates hyperglycemia and the healthcare provider has prescribed a PRN (as needed) dose of regular insulin for high blood sugar, administering insulin may be necessary to address hyperglycemia promptly. This is in line with diabetes management protocols, and the nurse should follow specific orders and guidelines for insulin administration.

A. Initiate cardiac telemetry:
Cardiac telemetry is not the immediate priority in this case. Kidney stones are more likely to cause severe localized pain rather than cardiac-related symptoms.

B. Administer a PRN dose of a laxative:
Laxatives are not indicated for the management of kidney stones or the associated flank pain. The priority is to address the specific needs related to the possible passage of kidney stones.

C. Implement seizure precautions:
Seizure precautions are not relevant to the sudden onset of severe flank pain in the context of hyperparathyroidism. The focus should be on managing pain, assessing for kidney stone passage, and addressing the underlying cause.

D. Begin straining all urine.
Straining all urine allows for the collection and examination of any passed stones. This information is important for identifying the composition of the stones and guiding further management.
