A client comes to the clinic for assessment of his physical status and guidelines for starting a weight-reduction diet. The client's weight is 216 pounds and his height is 66 inches. The nurse identifies the BMI (body mass index) as:
Correct Answer: C
Rationale: Obesity is defined by a BMI of 30 or more with no co-morbid conditions. It is calculated by utilizing a chart or nomogram that plots height and weight.

Question 4 of 5
Laboratory tests reveal the following electrolyte values for Mr. Smith: Na 135 mEq/L, Ca 8.5 mg/dL, Cl 102 mEq/L, and K 2.0 mEq/L. Which of the following values should the nurse report to the physician because of its potential risk to the client?
Correct Answer: B
Rationale: A potassium level of 2.0 mEq/L is critically low (normal 3.5-5.5 mEq/L), risking cardiac arrhythmias, and should be reported immediately.
Question 5 of 5
Assessment of the client with an arteriovenous fistula for hemodialysis should include:
Correct Answer: B
Rationale: Thrill should be present. The client should be taught to check this daily at home. Pulsation is not typically visible. Percussion gives no information about the patency of a fistula. Blood pressure is not auscultated in a limb with an AVF. Auscultation of the AVF, for a bruit, is part of an assessment for patency.
