A nurse is reinforcing teaching with a client who has anemia and has a prescription for ferrous sulfate. Which of the following foods should the nurse recommend that the client consume to increase the absorption of this medication?

The correct answer is choice B: Store opened insulin vials at room temperature for up to 4 weeks.

Choice B rationale: Opened insulin vials can be stored at room temperature (59°F to 86°F or 15°C to 30°C) for up to 4 weeks. After this period, the insulin may lose potency, and a new vial should be used.

Choice A rationale: Regular insulin is short-acting, and its peak effect occurs 2 to 3 hours after administration. Eating a snack 6 hours after insulin administration may not be necessary as the insulin would have already reached its peak effect, and blood glucose levels should be monitored accordingly.

Choice C rationale: Warming the insulin vial to dissolve crystals is not recommended. Insulin should be inspected before use, and if crystals or clumps are present, it should be discarded as this could indicate that the insulin has lost its effectiveness.

Choice D rationale: Unopened insulin vials should be stored in the refrigerator (36°F to 46°F or 2°C to 8°C) and should not be frozen. Freezing can cause insulin to lose potency or become ineffective. Once opened, insulin vials can be stored at room temperature for up to 4 weeks, as mentioned in choice B.

The correct answer is choice C. The client's lactose intolerance places her at an increased risk for osteoporosis, as dairy products are a rich source of calcium and vitamin D, which are important for bone health. Walking daily and gardening may actually help to reduce the risk of osteoporosis, as physical activity can help to strengthen bones. Drinking red wine in moderation may provide some benefits for cardiovascular health and may not necessarily increase the risk of osteoporosis.
Reason why each of the other choices are not answers:

A is not correct because walking daily can help to improve bone health and reduce the risk of osteoporosis.

B is not correct because gardening can also provide physical activity and help to reduce the risk of osteoporosis.

D is not correct because propranolol does not typically cause increased hair growth, and requesting a dosage increase based on apical heart rate may not be necessary for all clients taking this medication.
