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?

Choice A rationale:

A swollen area on the calf can indicate deep vein thrombosis (DVT), which is a serious complication of immobility. Immobilization can lead to blood stasis in the veins, increasing the risk of clot formation. DVT can result in severe complications, such as pulmonary embolism, making it a critical concern that requires immediate attention.

Choice B rationale:

Increased blood pressure is not a direct complication of immobility. However, immobility can contribute to hypertension over time due to factors such as weight gain and reduced cardiovascular fitness. While hypertension is a concern, it is not an acute complication of immobility that necessitates immediate intervention.

Choice C rationale:

Decreased serum calcium levels are not a direct complication of immobility. Immobility can lead to bone density loss and potential fractures due to reduced weight-bearing activities, but it does not cause an acute decrease in serum calcium levels.

Choice D rationale:

Urinary frequency is not a typical complication of immobility. Immobility can affect the urinary system, potentially leading to urinary stasis and increased risk of urinary tract infections, but urinary frequency is not a direct result of immobility.

Choice A rationale:

Amputation, although a significant medical history, is not a contraindication to becoming a living kidney donor. The presence of an amputation does not directly impact the person's ability to donate a kidney to their parent.

Choice B rationale:

Primary glaucoma, a condition affecting the eyes, is also not a contraindication to kidney donation. While eye conditions can affect overall health, they do not specifically prevent an individual from donating a kidney if they are otherwise healthy.

Choice C rationale:

Hypertension (high blood pressure) is a contraindication to kidney donation. Individuals with hypertension are at a higher risk of developing kidney disease themselves. Additionally, donating a kidney could exacerbate their condition, potentially leading to further complications. Therefore, this is the correct choice.

Choice D rationale:

Osteoarthritis, a condition affecting the joints, is not a contraindication to kidney donation. Joint problems do not directly impact kidney function or the ability to donate a kidney.
