A nurse is providing teaching about health promotion activities for a client who has a new diagnosis of type 1 diabetes mellitus. Which of the following statements by the client indicates an understanding of the teaching?

Choice A rationale:
Increasing potassium consumption is unrelated to cephalexin, an antibiotic. It is not a necessary precaution or action to take while on this medication.
Choice B rationale:
Applying lotion to the skin to relieve itching is not related to cephalexin use. Itching is not a common side effect of this antibiotic, so the client's statement indicates a misunderstanding of the teaching.
Choice C rationale:
Avoiding sun exposure is essential while taking cephalexin because it is known to cause photosensitivity reactions. Sun exposure can lead to severe skin reactions, so the client's statement indicates an understanding of the teaching.
Choice D rationale:
Keeping the medication refrigerated is not necessary for cephalexin oral suspension. It should be stored at room temperature unless specified otherwise by the manufacturer. The client's statement suggests a misunderstanding of the medication storage instructions.

Choice A rationale:
High lipase is not a typical laboratory finding related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Lipase is an enzyme involved in lipid digestion and is more relevant in assessing pancreatic function.
Choice B rationale:
High creatine kinase-MB (CK-MB) is not associated with overusing prescribed diuretics or hyponatremia (low sodium level). CK-MB is a specific marker for myocardial damage and is usually elevated in conditions like myocardial infarction.
Choice C rationale:
Low hemoglobin is not directly related to overusing prescribed diuretics and a sodium level of 127 mEq/L. Low hemoglobin may indicate anemia or other hematological issues but this is not a typical finding in this scenario.
Choice D rationale:
The correct answer is low urine specific gravity. Overusing diuretics can lead to excessive urination, causing the urine to become more dilute with lower specific gravity. A low urine specific gravity indicates decreased urine concentration and can be a sign of fluid and electrolyte imbalances, including hyponatremia.
