A nurse is teaching a client how to draw up regular insulin and NPH insulin in the same syringe. Which of the following instructions should the nurse include?

Choice A reason: This is incorrect because alendronate is not safe during pregnancy, as it may harm the fetus or cause birth defects. The client should inform the provider if they are pregnant or planning to become pregnant before taking this medication.

Choice B reason: This is incorrect because the client should not lie down for at least 30 minutes after taking alendronate, as this may cause esophageal irritation, ulceration, or bleeding. The client should take alendronate with a full glass of water and swallow it whole, without chewing or crushing.

Choice C reason: This is incorrect because the client should not continue smoking while on alendronate, as smoking can worsen the bone loss and increase the risk of fractures. The client should quit smoking or reduce the amount of cigarettes they smoke.

Choice D reason: This is correct because the client should avoid alcohol with alendronate, as alcohol can also worsen the bone loss and increase the risk of fractures. Alcohol can also interact with alendronate and cause side effects, such as stomach upset, drowsiness, or liver damage.

Choice E reason: This is correct because the client should sit up for at least 30 minutes after taking alendronate, as this can prevent the medication from refluxing back into the esophagus and causing irritation, ulceration, or bleeding. The client should also avoid eating or drinking anything other than water for at least 30 minutes after taking alendronate, as this can reduce its absorption and effectiveness.

Choice A reason: This is incorrect because NPH insulin is normally cloudy and should be gently mixed before use. However, the nurse should discard the solution if it has clumps, flakes, or crystals.

Choice B reason: This is correct because NPH insulin is an intermediate-acting insulin that has a slower onset and longer duration than short-acting or rapid-acting insulins. The nurse should explain to the client that NPH insulin provides basal coverage and may need to be combined with other types of insulin to control blood glucose levels.

Choice C reason: This is incorrect because freezing insulin can damage its potency and effectiveness. The nurse should instruct the client to store unopened insulin vials in the refrigerator and opened vials at room temperature.

Choice D reason: This is incorrect because shaking insulin can cause air bubbles and frothing, which can affect the accuracy of the dose. The nurse should instruct the client to roll the insulin vial between the palms of the hands to mix it gently.
