The nurse is caring for a patient with obesity who is being considered for bariatric surgery. Which do the criteria guidelines for bariatric surgery include?

BMI of 28 kg/m² or more

BMI of 32 kg/m² or more with other significant co-morbidities

BMI of 30 kg/m² or more

Body mass index (BMI) of 40 kg/m² or more

Answer and Explanation

The Correct Answer is D

A. A BMI of 28 kg/m² is considered overweight, but it does not meet the threshold for bariatric surgery, which typically requires a BMI of 40 or more.
B. While a BMI of 32 kg/m² may be relevant when combined with significant co-morbidities (like type 2 diabetes or hypertension), the standard guideline for bariatric surgery generally requires a BMI of 40 or higher, or 35 with comorbid conditions.
C. A BMI of 30 kg/m² is classified as obese, but bariatric surgery is generally considered for those with a BMI of 40 or higher, or 35 with severe comorbidities.
D. A BMI of 40 kg/m² or more is the standard criteria for bariatric surgery, particularly when other treatments (such as diet, exercise, and medication) have failed, or when obesity-related health issues are present.

Correct Answer is ["B","C","D"]

Explanation

A. Moon face is typically associated with Cushing's syndrome, not acromegaly, which is characterized by changes in the hands, feet, and facial features rather than a rounded, moon-shaped face.
B. Enlarged distal extremities (hands and feet) are classic symptoms of acromegaly due to excessive growth hormone production.
C. Hepatomegaly (enlarged liver) is a common finding in acromegaly due to the overproduction of growth hormone, which affects organ size.
D. Coarse facial features (such as a protruding jaw, enlarged nose, and thickened lips) are a hallmark of acromegaly, resulting from the overgrowth of soft tissues.
E. Loss of color discrimination is not typically associated with acromegaly and may be seen in other conditions affecting the optic nerve or eye, but it is not a key symptom of acromegaly.

A. HCO3 above 26 mEq/L B. pH below 7.35 C. PaO2 below 70 mm Hg D. PaCO2 above 45 mm Hg

Correct Answer is B

Explanation

A. HCO3 (bicarbonate) levels above 26 mEq/L indicate alkalosis, not acidosis. In metabolic acidosis, the HCO3 levels would be low as the body attempts to neutralize excess acid.
B. In metabolic acidosis, the pH is expected to be below 7.35 because metabolic acidosis indicates an accumulation of acid or loss of bicarbonate, which lowers the blood pH.
C. PaO2 (partial pressure of oxygen) below 70 mm Hg typically indicates hypoxemia, not necessarily metabolic acidosis. The primary concern with metabolic acidosis is the balance of acid-base status, not oxygenation.
D. PaCO2 above 45 mm Hg would suggest respiratory acidosis rather than metabolic acidosis. In metabolic acidosis, the body compensates by hyperventilating to blow off CO2 and raise the pH, resulting in a normal or low PaCO2.
