A nurse is creating an activity plan for an older adult client. In the planning, the nurse considers the physiologic changes that may affect pulmonary function related to the normal aging process. Which of the following age-related physiologic changes should the nurse consider in the plan?

Choice A reason: Bleeding during peritoneal dialysis may cause the dialysate to appear pink or red, but it does not cause cloudiness. Therefore, this option is incorrect.

Choice B reason: Cloudy dialysate outflow is a classic sign of peritonitis, which is the most common and serious complication of peritoneal dialysis. Peritonitis occurs due to infection within the peritoneal cavity, often introduced during catheter handling. The cloudiness is caused by the presence of white blood cells and bacteria in the dialysate. This makes option B the correct answer.

Choice C reason: Poor dialysate flow is usually due to mechanical issues such as catheter malposition, constipation, or obstruction. It results in reduced or absent drainage but does not cause cloudiness. Thus, this option is incorrect.

Choice D reason: Fibrin clot formation can obstruct the catheter and reduce dialysate flow, but it does not cause the effluent to appear cloudy. Instead, fibrin strands may be visible in the fluid. This option is incorrect because it does not explain the cloudy appearance.

Choice A reason: The prescription "Atropine .4 mg IV stat" is incorrect because it uses a leading decimal without a zero before the decimal point. This can lead to medication errors, as ".4 mg" could be misread as "4 mg." Correct documentation should be "Atropine 0.4 mg IV stat." Therefore, this option is unsafe and incorrect.

Choice B reason: The prescription "Lorazapam 1.0 mg IV PRN every 6 hr" is incorrect because it uses a trailing zero after the decimal point. Trailing zeros increase the risk of misinterpretation (e.g., "1.0 mg" could be misread as "10 mg"). Correct documentation should be "Lorazepam 1 mg IV PRN every 6 hr." This option is incorrect due to unsafe formatting.

Choice C reason: The prescription "Sucralfate 1 g PO 1 hr ac" is correct. It specifies the medication, dose, route, and timing clearly. "PO" indicates oral administration, and "1 hr ac" means one hour before meals, which is the appropriate timing for sucralfate to coat the stomach lining. This option is the correct answer because it follows proper documentation standards.

Choice D reason: The prescription "Enoxaparin 30 mg SC every 12 hr" is incorrect because the abbreviation "SC" for subcutaneous is discouraged. The preferred abbreviation is "subcut" or "subcutaneous" to avoid confusion with "SL" (sublingual). Therefore, this option is not considered correct documentation.
