While caring for a client receiving total parenteral nutrition (TPN), it is most important for the nurse to monitor which of the client's lab values?
Urinary ketones.
Serum protein.
Serum osmolarity.
Capillary glucose.
The Correct Answer is C
Choice A
Urinary ketones are not most important. Monitoring urinary ketones can provide information about the utilization of glucose and fat as energy sources. However, it is not the primary lab value to monitor in TPN administration.
Choice B
Serum protein is not most important. Monitoring serum protein levels is important to assess nutritional status, but it might not be as immediate a concern as serum osmolarity.
Choice C
Serum osmolarity is the most important. When caring for a client receiving total parenteral nutrition (TPN), monitoring serum osmolarity is most important. TPN is a highly concentrated solution containing various nutrients, and it is infused directly into the bloodstream. Serum osmolarity reflects the concentration of particles (such as electrolytes, glucose, and other solutes) in the blood. Monitoring serum osmolarity is crucial to prevent complications related to fluid and electrolyte imbalances that can arise from the administration of TPN.
Choice D
Capillary glucose is not the most important. Monitoring capillary glucose levels is important, especially in clients receiving TPN with added glucose. Hyperglycaemia is a potential complication of TPN. While glucose monitoring is important, it is secondary to monitoring serum osmolarity, which encompasses a broader range of solute concentrations.

Correct Answer is D
Explanation
Choice A
Nuts is incorrect. Nuts are a good source of healthy fats, including monounsaturated and polyunsaturated fats, which can actually have a positive impact on heart health. They have been associated with improving HDL cholesterol levels and can be a part of a heart-healthy diet. While nuts are calorie-dense, small portions can be included as part of the client's diet to replace less healthy snacks. Therefore, nuts might not need to be completely avoided.
Choice B
Shellfish Is incorrect. Shellfish, including shrimp, crab, and lobster, are relatively low in saturated fat and cholesterol. While they do contain cholesterol, dietary cholesterol has less impact on blood cholesterol levels compared to saturated and trans fats. The client's main concern is elevated LDL cholesterol, which is influenced more by saturated fat intake. Therefore, avoiding shellfish might not be as crucial as focusing on saturated fat sources.
Choice C
Eggs is incorrect. Eggs are a source of dietary cholesterol, but they also provide essential nutrients. Recent research suggests that dietary cholesterol from foods like eggs has less impact on blood cholesterol levels for most people than was previously thought. For the client, the more significant concern is the elevated LDL cholesterol level. If the client enjoys eggs, they might not need to completely avoid them, but they should consume them in moderation and consider other dietary changes to reduce saturated fat intake.
Choice D
Cheese is correct. Cheese is often high in saturated fats, which can contribute to elevated LDL cholesterol levels. Therefore, it would be important for the client to limit their intake of high-fat cheeses.
Correct Answer is B
Explanation
Choice A
Client with a nasogastric tube to low, intermittent suction is not correct. While there is a risk of aspiration with a nasogastric tube in place, the tube is intended to help drain stomach contents, reducing the risk of aspiration. However, if the tube is not properly positioned or managed, there could still be some risk.
Choice B
Client who has sensory aphasia and is receiving a clear liquid diet is correct. Sensory aphasia refers to a language disorder that affects a person's ability to understand language and communication. This client may have difficulty swallowing safely and effectively, which increases the risk of aspiration. Additionally, a clear liquid diet consists of thin liquids that are more likely to be aspirated compared to thicker fluids.
Choice C
Client receiving 30% oxygen via a non-rebreather face mask is not correct. Oxygen therapy can increase the risk of drying the airways and potentially increasing the risk of aspiration, but if the oxygen mask is properly fitted and humidified, the risk may be minimized.
Choice D
Client experiencing dysphagia who is prescribed a full liquid diet is not correct. Dysphagia refers to difficulty swallowing, which can increase the risk of aspiration. However, a full liquid diet includes thicker liquids that are less likely to be aspirated compared to thin liquids. Still, the risk of aspiration exists, especially if the client has severe dysphagia.
