A. The client who has a history of rheumatoid arthritis complaining of 5/10 pain in the joints of his hands. B. The client who requires a chlorhexidine scrub prior to a double mastectomy this morning. C. The client who can have nothing by mouth for a scheduled surgery this morning and received an ordered dose of insulin glargine the night before. D. The client who is receiving digoxin with a blood pressure of 100/75 mmHg.

Correct Answer is D

Explanation

a) Pain in a client with a history of rheumatoid arthritis is important but may not require immediate attention compared to potential complications of medication administration.

b) Preparing a client for a chlorhexidine scrub is important, but it is not an immediate priority compared to potential complications related to medication and vital signs.

c) A client who cannot have anything by mouth before surgery and received insulin glargine the night before needs monitoring, but it may not require immediate assessment compared to the potential complications of the client receiving digoxin with a blood pressure of 100/75 mmHg.

d) The client receiving digoxin with a blood pressure of 100/75 mmHg is at risk for toxicity, as low blood pressure may increase the concentration of digoxin. This client should be assessed first to prevent potential complications.
