Correct Answer is B

Explanation

A. While individuals with bulimia nervosa may experience fluctuations in their weight, they are not typically significantly underweight like those with anorexia nervosa. They often maintain a weight within or slightly below the normal range.
B. Dental decay is a common finding in people with bulimia nervosa due to self-induced vomiting, which exposes the teeth to stomach acid. This acid can erode enamel, leading to cavities, tooth decay, and other dental issues.
C. Hyperkalemia is not typically associated with bulimia nervosa. Hypokalemia (low potassium) is more common in bulimia, especially due to vomiting and laxative use, which can lead to significant potassium depletion.
D. Amenorrhea is more common in anorexia nervosa, where extreme malnutrition often leads to the cessation of menstruation. In bulimia nervosa, menstrual irregularities may occur, but complete amenorrhea is not as typical as in anorexia.

A. Hypoventilation B. Cheyne Stokes respirations C. Kussmaul respirations D. Central apnea

Correct Answer is C

Explanation

A. Hypoventilation refers to shallow or slow breathing, which is not typically seen in diabetic ketoacidosis (DKA).
B. Cheyne-Stokes respirations involve a pattern of alternating deep and shallow breaths, often seen in patients with neurological conditions or severe heart failure, not in DKA.
C. Kussmaul respirations are deep, rapid breaths and are a classic sign of diabetic ketoacidosis (DKA). This respiratory pattern is the body’s attempt to compensate for metabolic acidosis, as seen in DKA, by blowing off CO2 to reduce acidity in the blood.
D. Central apnea refers to a cessation of breathing due to a failure of the brain to send signals to the respiratory muscles and is not associated with DKA.
