The nurse, instructing a client on the prevention of osteoporosis, includes the importance of maintaining a normal serum calcium level because:
1. calcium influences the contraction of skeletal muscle.
2. calcium ions assist in blood clotting.
3. appropriate nerve conduction depends on an adequate calcium level.
4. the support provided by bones is important for the structural integrity of the body.
Correct Answer: 4
Rationale 1: Calcium is important in the contraction of muscle, but this function is not related to osteoporosis.
Rationale 2: Calcium does assist the process of blood clotting, but this function is not related to osteoporosis.
Rationale 3: The excitability of nerves is dependent on adequate calcium, but this function is not related to osteoporosis.
Rationale 4: Calcium is bound as a hard matrix known as hydroxyapatite crystals that provides support to the skeleton.
