An older patient reports a significant amount of cheese, milk, and calcium-fortified orange juice in her diet. She also takes a 750 mg calcium supplement at breakfast. What should the nurse instruct the patient about her calcium intake?
A) Keep the intake of calcium to 30% of kilocalories or less
B) Take calcium supplement doses totaling not more than 5,000 mg
C) Limit the intake of calcium to a total of 2,000 mg or less from all sources
D) Follow the RDA listed on the milk products' nutrition labels for calcium intake
C
Feedback:
If the patient has a daily calcium intake of greater than 2,000 mg, she may be at risk for kidney stones. Patients should check labels of food as well as supplements to ensure that the contents do not add up to excessive calcium consumption; however, the RDA listed on milk products' nutritional labels for calcium intake may be too great for the older patient. Calcium does not contribute to caloric intake. Calcium supplements totaling not more than 5,000 mg is too high an amount for most adults.

If only a small volume of sperm is discharged into the vagina, an insufficient amount of enzymes might be released when they encounter the ovum. In that case, pregnancy would probably not result, because:
1. Peristalsis of the fallopian tube would decrease, making it difficult for the ovum to enter the uterus. 2. The block to polyspermy (cortical reaction) would not occur. 3. The fertilized ovum would be unable to implant in the uterus. 4. Sperm would be unable to penetrate the zona pellucida of the ovum.
