A nurse is caring for a client with a current blood potassium level of 5.4 mEq/L (3.5-5 mEq/L). Which finding would this client have?

A) Constipation: Elevated potassium levels (hyperkalemia) typically affect neuromuscular and cardiac function rather than gastrointestinal motility. Constipation is more commonly associated with conditions like hypokalemia or electrolyte imbalances affecting the gastrointestinal system.

B) Polyuria: Polyuria, or excessive urination, is not directly caused by hyperkalemia. It can occur due to conditions like diabetes mellitus or diabetes insipidus, or as a side effect of certain medications like diuretics. Hyperkalemia does not typically lead to increased urine output and may even lead to oliguria if severe renal impairment occurs.

C) EKG with a U wave: The presence of a U wave on an electrocardiogram (EKG) is typically associated with hypokalemia, not hyperkalemia. U waves are seen when potassium levels are low, reflecting delayed repolarization of the ventricles. In hyperkalemia, EKG changes more commonly include peaked T waves, prolonged PR interval, and widened QRS complexes.

D) Paresthesias of the extremities: Hyperkalemia can cause paresthesias, which are sensations of tingling or numbness, particularly in the extremities. This occurs due to the effect of elevated potassium levels on nerve and muscle function. As potassium is essential for maintaining normal neuromuscular function, deviations from normal levels can disrupt action potentials and lead to sensory disturbances like paresthesias.

A) Popsicle:
A popsicle is appropriate for a clear liquid diet because it is made from clear liquids and does not contain any solids or pulp. Clear liquids are defined as those that are transparent at room temperature, making popsicles a suitable option.

B) Milkshake:
A milkshake is not suitable for a clear liquid diet due to its creamy consistency and solid particles. Clear liquid diets require that all items be transparent and free of any solid components.

C) Orange juice with pulp:
Orange juice with pulp is not appropriate for a clear liquid diet because it contains pulp, which is considered a solid. Clear liquid diets exclude any liquids that have solid components or particulate matter.

D) Yogurt:
Yogurt is not allowed on a clear liquid diet as it contains solids and has a creamy texture. Clear liquid diets are limited to liquids that are completely transparent and free of solids.
