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?

A.

42

B.

28

C.

32

D.

24

Answer and Explanation

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 C

Explanation

Rationale:

A. Drinks 3 cups of 1% milk per day: This intake is appropriate for an 8-year-old child. It supports bone development by providing sufficient calcium and vitamin D, aligning with dietary guidelines for school-age children.

B. Weight has increased by 5 kg (11 lb): A weight gain of about 2–3 kg (4.4–6.6 lb) per year is typical for children between ages 6 and 12. A 5 kg increase over one year is within normal limits and does not require provider notification unless accompanied by other concerns.

C. Height has increased by 3.8 cm (1.5 in): This is below the expected annual growth rate for an 8-year-old, which is typically 5 to 6.5 cm (2 to 2.5 in) per year. Slowed linear growth can indicate underlying medical or nutritional issues and should be reported for evaluation.

D. Consumes three meals and two snacks per day: This is a healthy and age-appropriate eating pattern for a school-age child, promoting stable energy levels and supporting growth and development.

Explanation

Rationale:

  • Platelet count: A low platelet count (<100,000/mm³) is a hallmark of HELLP syndrome but can also appear in severe preeclampsia. Therefore, thrombocytopenia supports both diagnoses.
  • Alanine aminotransferase (ALT): Elevated ALT indicates hepatic involvement due to hepatocellular injury, which is a defining feature of HELLP syndrome but not required for preeclampsia diagnosis.
  • Blood pressure: Severe hypertension (≥160/110 mm Hg), as seen in this client, is diagnostic of severe preeclampsia. It may also be present in HELLP syndrome due to overlapping pathophysiology.
  • Hemoglobin: Low hemoglobin can reflect hemolysis, which is part of the HELLP acronym (Hemolysis, Elevated Liver enzymes, Low Platelets). Preeclampsia does not typically present with anemia unless HELLP develops.
