A nurse is teaching a client who has diabetes mellitus and receives 25 units of NPH insulin every morning if their blood glucose level is above 200 mg/dL. Which of the following information should the nurse include?
Discard the NPH solution if it appears cloudy.
NPH is an intermediate-acting insulin.
Freeze unopened insulin vials.
Shake the insulin vigorously before loading the syringe.
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A reason: 0.2 tablets is not the correct answer. To convert mg to mcg, multiply by 1000. Therefore, 0.175 mg is equal to 175 mcg. To find the number of tablets, divide the dose by the amount available. Therefore, 175 mcg / 8 mcg = 21.875 tablets. Round this to the nearest whole number, which is 22 tablets.
Choice B reason: 2 tablets is not the correct answer. This is the result of dividing the dose by 100 instead of 1000, which is incorrect.
Choice C reason: 20 tablets is not the correct answer. This is the result of rounding down instead of up, which is incorrect.
Choice D reason: 22 tablets is the correct answer. This is the result of converting the dose to mcg, dividing by the amount available, and rounding to the nearest whole number.
Correct Answer is B
Explanation
Choice A reason: Benzonatate is not the correct answer. Benzonatate is a cough suppressant that works by numbing the throat and lungs. It does not help in the removal of mucus.
Choice B reason: Guaifenesin is the correct answer. Guaifenesin is an expectorant that works by thinning and loosening the mucus in the airways. It helps in the removal of mucus by making it easier to cough up.
Choice C reason: Diphenhydramine is not the correct answer. Diphenhydramine is an antihistamine that works by blocking the effects of histamine, a chemical that causes allergy symptoms. It does not help in the removal of mucus.
Choice D reason: Dextromethorphan is not the correct answer. Dextromethorphan is a cough suppressant that works by affecting the signals in the brain that trigger the cough reflex. It does not help in the removal of mucus.
