A nurse is calculating the BMI of a client who has a weight of 75 kg (165.3 lb) and a height of 1.8 m (5 ft 9 in). Which of the following values should the nurse calculate as the client's BMI?
42
28
32
24
The Correct Answer is D
Rationale:
A. 42: A BMI of 42 falls in the category of class III (severe) obesity. This would only occur if the client's weight were significantly higher than 75 kg for a height of 1.8 m.
B. 28: A BMI of 28 indicates overweight status. At 75 kg and 1.8 m tall, the client does not meet the weight requirement for a BMI this high, as 28 would correspond to a weight closer to 91 kg.
C. 32: A BMI of 32 falls in the obesity range. For someone who is 1.8 m tall, a BMI of 32 would require a weight of about 104 kg, which is much higher than the client’s actual weight of 75 kg.
D. 24: The BMI is calculated as weight (kg) divided by height (m²). Using the formula:
BMI = 75 / (1.8 × 1.8) = 75 / 3.24 ≈ 23.15, which rounds to 24, placing the client in the normal weight range.

Correct Answer is B
Explanation
Rationale:
A. Autonomy: Autonomy involves respecting a client’s right to make their own healthcare decisions. While important, this scenario concerns unequal treatment rather than limiting the clients’ decision-making rights.
B. Justice: Justice refers to fairness and equity in the distribution of healthcare resources. Providing supplies to one client based on insurance status while denying them to another reflects unequal and unethical treatment, violating the principle of justice.
C. Beneficence: Beneficence means acting in the best interest of the client by promoting well-being. Although the insured client is benefitting, failing to support the uninsured client equally undermines the overall intent to do good for all clients.
D. Nonmaleficence: Nonmaleficence is the obligation to do no harm. While denying supplies could lead to harm, the primary ethical breach in this situation lies in the unfair distribution of care, which relates more directly to justice.
