The nurse is preparing to administer insulin intravenously. Which statement about the administration of intravenous insulin is true?
Insulin is never given intravenously.
Only regular insulin can be administered intravenously.
Insulin aspart or insulin lispro can be administered intravenously, but there must be a 50% dose reduction.
Any form of insulin can be administered intravenously at the same dose as that ordered for subcutaneous administration.
The Correct Answer is B
Choice A reason: This is incorrect because insulin can be given intravenously in certain situations, such as diabetic ketoacidosis, hyperglycemic hyperosmolar state, or perioperative care.
Choice B reason: This is correct because regular insulin is the only type of insulin that can be administered intravenously, as it is a short-acting insulin that has a rapid onset and peak. Other types of insulin, such as intermediate-acting or long-acting, are not suitable for intravenous use, as they have a delayed onset and peak and may cause hypoglycemia.
Choice C reason: This is incorrect because insulin aspart and insulin lispro are rapid-acting insulins that have a faster onset and peak than regular insulin. They are not recommended for intravenous use, as they may cause severe hypoglycemia. They are usually given subcutaneously before meals to control postprandial blood glucose levels.
Choice D reason: This is incorrect because not all forms of insulin can be administered intravenously, as explained above. Only regular insulin can be given intravenously, and the dose may differ from the subcutaneous dose depending on the patient's blood glucose level and insulin sensitivity.

Correct Answer is D
Explanation
Choice A reason: This is incorrect because reporting symptoms that last longer than 2 days is not specific to guaifenesin. This is a general instruction for any patient with a sinus infection, regardless of the medication they are taking.
Choice B reason: This is incorrect because reporting clear-colored sputum to the prescriber is not necessary. Clear-colored sputum indicates that the infection is improving and the mucus is thinning. This is a desired effect of guaifenesin, not a problem that needs to be reported.
Choice C reason: This is incorrect because guaifenesin does not have sedating effects. Guaifenesin is an expectorant that helps to break up and expel mucus from the respiratory tract. It does not cause drowsiness or impair the ability to drive or operate machinery.
Choice D reason: This is correct because increasing fluid intake is an important instruction for a patient taking guaifenesin. Fluids help to hydrate the body and thin the mucus, making it easier to cough up and clear the sinuses. Fluids also help to prevent dehydration and dryness of the mucous membranes.
Correct Answer is D
Explanation
Choice A reason: This is incorrect because insulin glargine has a longer duration than 6 to 10 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.
Choice B reason: This is incorrect because insulin glargine has a longer duration than 3 to 6 hr. Insulin glargine is not a short-acting or rapid-acting insulin that peaks quickly and lasts for a few hours. It is a long-acting insulin that does not have a peak and lasts for up to 24 hr.
Choice C reason: This is incorrect because insulin glargine has a longer duration than 16 to 24 hr. Insulin glargine is a long-acting insulin that can last for up to 24 hr, but not more than that. It is not an ultra-long-acting insulin that can last for more than 24 hr.
Choice D reason: This is correct because insulin glargine has a duration of 18 to 24 hr. Insulin glargine is a long-acting insulin that provides a steady and continuous level of insulin in the blood. It is usually given once daily at the same time.
