Obesity II

overweight

Normal weight

Obesity

Answer and Explanation

The Correct Answer is A

A) Obesity II:

A Body Mass Index (BMI) of 37 falls within the range of 35 to 39.9, which is classified as Obesity Class II according to the World Health Organization (WHO) BMI categories. This classification indicates a higher risk of obesity-related health conditions and complications.

B) Overweight:

The overweight category corresponds to a BMI range of 25 to 29.9. A BMI of 37 is significantly higher than this range, indicating a more severe level of excess weight and associated health risks.

C) Normal weight:

Normal weight is defined by a BMI range of 18.5 to 24.9. A BMI of 37 is well above this range, indicating that the patient has excess body weight far beyond what is considered normal.

D) Obesity:

While the term "obesity" generally refers to a BMI of 30 or higher, specific classes of obesity (Class I, II, and III) are defined for more precise categorization. A BMI of 37 specifically places the patient in the Obesity II category.

Correct Answer is C

Explanation

A. Nail Beds:

While peripheral cyanosis can cause bluish discoloration of the nail beds, central cyanosis is more indicative of systemic hypoxemia and is best assessed in areas with rich blood supply, such as the oral mucosa.

B. Sclera:

The sclera is more commonly used to assess for jaundice (yellowing) rather than cyanosis. Cyanosis is not typically visible in the sclera.

C. Oral Mucosa:

Central cyanosis is most accurately assessed in areas with high vascularization, such as the oral mucosa. This area provides a clear indication of oxygenation status and can reveal hypoxemia more reliably than peripheral sites.

D. Palms:

Similar to the nail beds, the palms can show signs of peripheral cyanosis but are not the primary site for assessing central cyanosis. The oral mucosa remains the best site for this assessment.

A. Mucous Membranes B. Dorsal surface of the hand C. Dorsal surface of the foot D. Pinnae of the ears

Correct Answer is A

Explanation

A. Mucous Membranes:

In clients with dark skin, mucous membranes such as the lips, tongue, and gums are the best sites to assess for cyanosis. These areas have less pigmentation and are more vascular, allowing for a more accurate evaluation of oxygenation and the presence of cyanosis.

B. Dorsal surface of the hand:

The dorsal surface of the hand can be used to assess for cyanosis in lighter-skinned individuals, but it is less reliable in dark-skinned clients due to the higher melanin content, which can obscure the bluish tint indicative of cyanosis.

C. Dorsal surface of the foot:

Similar to the dorsal surface of the hand, the dorsal surface of the foot is not an ideal site for assessing cyanosis in clients with dark skin. The presence of melanin can make it difficult to detect changes in skin color.

D. Pinnae of the ears:

The pinnae of the ears are also not the best sites for assessing cyanosis in dark-skinned clients. These areas can be highly pigmented, which can mask the bluish discoloration associated with cyanosis. The mucous membranes remain the most reliable site for this assessment.
