Correct Answer is B

Explanation

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.

A. 0.2 tablets B. 2 tablets C. 20 tablets D. 22 tablets

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.
