During a conversation with the nurse, a patient comments that he rarely goes outside when the sun is shining because he is afraid of developing skin cancer. Which health problem is this patient at risk for developing?
1. vitamin D deficiency
2. hypercholesterolemia
3. hypokalemia
4. hypernatremia
Correct Answer: 1
The skin functions as a synthesizer of vitamin D (sunlight reacts with cholesterol). Hypercholesterolemia results from factors such as dietary intake and cholesterol that is produced by the body. The skin does retard the loss of fluid and does play a role in fluid and electrolyte balance. However, avoiding the sun does not increase the patient's risk of developing hypokalemia or hypernatremia.
