A nurse is caring for a client who has end-stage kidney disease. The client's adult child asks the nurse about becoming a living kidney donor for their parent. Which of the following conditions in the child's medical history should the nurse identify as a contraindication to the procedure?

Rationale: A. Primary glaucoma affects intraocular pressure and vision but does not directly impact kidney function or surgical suitability for kidney donation. It is not considered a contraindication to living kidney donation unless there are severe complications affecting overall surgical risk, which is uncommon. B. A history of amputation does not automatically disqualify a person from being a kidney donor. Eligibility depends on overall health status, kidney function, and ability to tolerate surgery. Amputation alone is not a contraindication. C. Hypertension is a significant contraindication or at least a major exclusion criterion for living kidney donation in many cases. Chronic high blood pressure can damage the kidneys over time and increases the risk of future renal impairment after donation. Donors must have well-controlled blood pressure and no evidence of end-organ damage to be considered; uncontrolled or long-standing hypertension is generally disqualifying. D. Osteoarthritis is a degenerative joint condition that does not affect kidney function or surgical eligibility for donation. It is not a contraindication unless it severely limits mobility to the point of affecting recovery, which is not typical.
