The common bile duct empties into which of the following structures of the gastrointestinal tract?

A. Low blood pressure is not typically associated with elevated potassium levels. While severe hyperkalemia can impact the cardiovascular system, it does not directly cause low blood pressure as a primary symptom.

B. Rapid respirations are generally associated with conditions like acidosis or respiratory distress but are not a primary consequence of elevated potassium levels.

C. Elevated potassium levels are not typically associated with constipation. In fact, hyperkalemia can cause gastrointestinal symptoms such as nausea or abdominal cramping, but constipation is more commonly linked to conditions like low potassium levels (hypokalemia).

D. Elevated potassium levels, or hyperkalemia, can cause cardiac irregularities such as arrhythmias, which can be life-threatening if not managed promptly. This is the most significant and direct effect of high potassium levels in the blood.

A. The Bundle of His is the pathway that carries the electrical impulse from the AV node to the right and left bundle branches, which leads to the Purkinje fibers and ultimately causes the ventricles to contract.

B. The Purkinje fibers are the last component of the conduction system, responsible for rapidly transmitting the impulse to the ventricular muscle to trigger contraction, but the impulse must first travel through the Bundle of His.

C. The SA node is the natural pacemaker of the heart, initiating the electrical impulse, but the impulse does not travel to the SA node after the AV node. The SA node sends impulses to the atria first.

D. The bundle branches are part of the conduction system that transmits the electrical impulse to the Purkinje fibers. The impulse reaches the bundle branches after traveling through the Bundle of His.
