A nurse is caring for a client who has hypertension and is taking lisinopril. The nurse should monitor the client for which of the following findings as an adverse effect of lisinopril?

A) "Wash hands for 10 seconds after caring for the client.": Proper hand hygiene is critical in preventing the spread of infections, but the recommended duration for handwashing is at least 20 seconds. This option does not specify the necessary steps to ensure effective hand hygiene.

B) "Monitor the client for manifestations of dehydration.": Older adults are at a higher risk of dehydration due to gastroenteritis, which can cause significant fluid loss through vomiting and diarrhea. Monitoring for signs of dehydration, such as dry mucous membranes, decreased skin turgor, and reduced urine output, is a priority in managing their condition and preventing complications.

C) "Use toilet paper to remove stool from the client's skin.": While keeping the client clean is important, using toilet paper might not be sufficient or gentle enough to effectively clean and protect the skin. Using appropriate cleansing methods and skin care products is better for maintaining skin integrity.

D) "Administer diphenoxylate/atropine to the client.": While this medication can help reduce diarrhea, it may not be the first action to take. In some cases, stopping diarrhea too quickly can prevent the elimination of harmful pathogens. Monitoring and addressing hydration status is more critical initially in the management of gastroenteritis.

A) Bicarbonate 26 mEq/L: A bicarbonate level of 26 mEq/L is within the normal range (22-28 mEq/L) and does not indicate metabolic acidosis, which is characteristic of diabetic ketoacidosis (DKA). In DKA, bicarbonate levels are usually decreased due to buffering of the excess acids.

B) Serum pH 7.32: A serum pH of 7.32 is indicative of acidemia, which is consistent with metabolic acidosis seen in DKA. The pH is typically lower than the normal range (7.35-7.45) in DKA due to the accumulation of ketoacids.

C) Creatinine 1.2 mg/dL: A creatinine level of 1.2 mg/dL is slightly elevated but does not specifically indicate metabolic acidosis. Elevated creatinine may suggest renal impairment but is not directly linked to the acid-base disturbance seen in DKA.

D) BUN 20 mg/dL: A blood urea nitrogen (BUN) level of 20 mg/dL is elevated and may indicate dehydration or kidney dysfunction but does not specifically diagnose the acid-base imbalance associated with DKA. In DKA, bicarbonate and pH levels are more directly affected.
