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 A
Explanation
Rationale:
A. “You can obtain a personal response system that will be activated if you fall.": Personal emergency response systems (PERS) allow individuals who live alone to call for help immediately in case of a fall or emergency.
B. “You need to move to a skilled nursing facility where they can prevent falls.": Moving to a skilled nursing facility is a major step and is not necessary solely due to fear of falling. It may also provoke anxiety or feelings of loss of autonomy, especially if less invasive alternatives are available.
C. "You can have an unlicensed assistive personnel (UAP) come to your house daily to stay with you.": Daily UAP support may not be realistic or necessary for someone who is still generally independent. This level of care may be excessive unless the client has significant mobility or cognitive impairments.
D. "You should contact a family member once a week to keep in touch.": While weekly contact with family can offer emotional support, it does not provide real-time assistance in the event of a fall. It’s not a sufficient solution for immediate safety concerns.

Explanation
Rationale:
- Sensation: Tingling indicates possible nerve irritation or mild neurovascular compromise. This is often seen in fractures when swelling or bone displacement compresses nerves near the injury site, especially in long bones like the radius.
- Ecchymosis: Bruising results from soft tissue bleeding and is common in all three conditions due to trauma to blood vessels. Ligament tears (sprain), bone injury (fracture), and capsule damage (dislocation) can all lead to ecchymosis.
- Pain level: Moderate pain, such as a 4/10 rating, is consistent with both sprains and fractures. Sprains stretch or tear ligaments, while fractures disrupt bone structure. Dislocations usually present with severe, sharp pain that impairs joint movement entirely.
- Edema: Swelling is a nonspecific but common response to tissue injury. It occurs with ligament strain (sprain), bone disruption (fracture), and joint trauma (dislocation), all of which lead to localized inflammation and fluid accumulation.
