Which of the following provides lubrication of the vagina during sexual excitement?

A. The ovaries are responsible for producing hormones such as estrogen and progesterone but do not directly produce lubrication during sexual excitement.
B. The cervix produces mucus that changes in consistency throughout the menstrual cycle but does not play a significant role in lubrication during sexual activity.
C. Skene's glands, located near the urethra, secrete fluid that is often compared to prostate fluid in males, but they do not play the primary role in vaginal lubrication during sexual excitement.
D. Bartholin's glands, located near the vaginal opening, secrete mucus that provides lubrication during sexual excitement, helping to reduce friction and enhance comfort during intercourse.

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.
