A patient prescribed spironolactone is demonstrating ECG changes and complaining of muscle weakness. The nurse realizes this patient is exhibiting signs of which electrolyte imbalance?

Widened QRS Complexes.

Choice A rationale:

Hyperactive deep tendon reflexes are not typical findings in respiratory acidosis. They are more commonly associated with conditions like hypocalcemia or hypercalcemia.

Choice B rationale:

Warm, flushed skin is not directly related to respiratory acidosis. It is not a typical manifestation of this acid-base imbalance.

Choice C rationale:

Widened QRS complexes on an ECG are characteristic findings in respiratory acidosis. Acidosis can lead to changes in the electrical conduction of the heart, resulting in QRS complex widening.

Choice D rationale:

Bounding peripheral pulses are not directly associated with respiratory acidosis. They may be seen in conditions like hyperthyroidism or anemia but are not specific to respiratory acidosis. Remember, always interpret lab results and clinical findings in the context of the patient's overall condition, medical history, and other relevant factors to provide the best care possible.

Choice A rationale:

Increased urine ketones are not indicative of fluid volume deficit. Instead, they may suggest diabetic ketoacidosis or starvation ketosis.

Choice B rationale:

Decreased Hgb (hemoglobin) is not specific to fluid volume deficit and can be seen in various conditions such as anemia or bleeding.

Choice C rationale:

Decreased urine specific gravity is not consistent with fluid volume deficit, as it usually results in concentrated urine with increased specific gravity.

Choice D rationale:

An increased blood urea nitrogen (BUN) level is expected in fluid volume deficit due to reduced kidney perfusion and function. BUN is a marker of kidney function and is elevated when fluid volume is low.
