Which of the following is associated with an elevated potassium level in the blood?
Low blood pressure
Rapid respirations
Constipation
Cardiac irregularities
The Correct Answer is D
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.

Correct Answer is B
Explanation
A. Lacrimal glands produce tears and are not involved in the formation of blackheads.
B. Sebaceous glands secrete sebum, an oily substance that can clog hair follicles when produced in excess. This blockage, combined with oxidation, leads to the formation of blackheads on the skin.
C. Sweat glands produce sweat and are not involved in the formation of blackheads, which result from excess sebum and not sweat.
D. Ceruminous glands secrete earwax (cerumen) and are not involved in blackhead formation, as they are located in the ear canal and not on the skin's surface.
