A nurse is contributing to the plan of care for a client who has a potassium level of 2.9 mEq/L. Which of the following actions should the nurse plan?

A. Copy of the client's advance directives: While advance directives are important documents, they are typically filed with the medical record, not specifically included in postmortem documentation. The focus for postmortem documentation is on the body and relevant events surrounding the death.

B. Cause of the client's death.: The cause of death is typically recorded in the official death certificate, which is not part of postmortem nursing documentation. The nurse should not make a diagnosis about the cause of death but may note any relevant findings.

C. Last set of the client's vital signs: Vital signs taken at the time of death may be noted as part of the clinical documentation, but they are not specifically part of postmortem documentation. The postmortem documentation should focus on observations regarding the body and its condition.

D. Location of the identification tag on the client’s body: The nurse should document the location of identification tags on the body to ensure proper identification and to prevent confusion or errors in postmortem care. This is an important detail in postmortem documentation.

A. BUN 18 mg/dL is incorrect. A BUN (blood urea nitrogen) level of 18 mg/dL is within the normal range (typically 7–20 mg/dL) and does not indicate immediate concern in this context. An elevated BUN could indicate dehydration, but this level is not significantly elevated.

B. Serum creatinine 1.0 mg/dL is incorrect. Serum creatinine levels are also within normal limits for most adults, which is around 0.6–1.2 mg/dL, and this finding does not indicate a problem.

C. Urine output 12 mL/hr is correct. A urine output of 12 mL/hr is low and indicates oliguria, which is a concern in the context of dehydration. The normal urine output for an adult is at least 30 mL/hr. A decrease in urine output suggests that the kidneys are not receiving adequate blood flow, which could indicate severe dehydration and requires immediate attention from the provider.

D. Urine specific gravity 1.020 is incorrect. Urine specific gravity of 1.020 is within the normal range (typically 1.005–1.030) and indicates that the kidneys are concentrating urine appropriately, which is not a concerning finding in this case.
