A patient is scheduled to start taking insulin glargine (Lantus). On the care plan, the nurse should include which of these outcomes related to the therapeutic effects of the medication?
Mealtime coverage of blood glucose
Blood glucose control for 24 hours
Less frequent blood glucose monitoring
Peak effect achieved in 2 to 4 hours
The Correct Answer is B
Choice A reason: Glargine provides basal, not insulin, coverage; meal coverage. It maintains steady glucose control, so this is incorrect.
Choice B reason: Insulin glargine offers 24-hour basal glucose control, stabilizing blood sugar without peaks. This is its primary effect, making it the correct outcome.
Choice C reason: Glargine requires regular monitoring, not less frequent monitoring, to ensure control. This is incorrect for the therapeutic outcome.
Choice D reason: Glargine has no peak, unlike short-acting insulins, with effects lasting 24 hours. A 2–4 hour peak is incorrect, so incorrect.

Correct Answer is C
Explanation
Choice A reason: Pentazocine is less effective for severe, chronic pain and has mixed agonist-antagonist effects. Fentanyl is stronger for opioid-tolerant patients, so this is incorrect.
Choice B reason: Hydrocodone is weaker than oxycodone and inadequate for severe, resistant pain. Fentanyl’s potency suits chronic cancer pain, so this is incorrect.
Choice C reason: Fentanyl transdermal is potent, long-acting, and ideal for severe, chronic cancer pain in opioid-tolerant patients. It’s appropriate here, making it the correct choice.
Choice D reason: Meperidine is not recommended for chronic pain due to neurotoxic metabolites. Fentanyl is safer and more effective, so this is incorrect.
Correct Answer is D
Explanation
Choice A reason: NPH insulin is not mixed with insulin glargine, as glargine’s pH and formulation cause precipitation or altered pharmacokinetics when combined. NPH can be mixed with regular insulin, as they are compatible, making this choice incorrect for the patient’s reported practice.
Choice B reason: NPH and regular insulin are compatible and routinely mixed in one syringe to provide both intermediate and short-acting coverage. They don’t react chemically or lose efficacy when combined properly, making this choice incorrect, as mixing is a standard practice in diabetes management.
Choice C reason: Mixing NPH and regular insulin does not increase potency; it combines their pharmacokinetics for basal and prandial glucose control. The mixture delivers the additive effects of each insulin’s profile without enhancing overall potency, making this choice inaccurate for their combined action.
Choice D reason: Mixing NPH (intermediate-acting) and regular insulin (short-acting) is an accepted practice to manage type 1 diabetes with one injection, covering basal and prandial needs. Proper technique (drawing regular insulin first) ensures stability, making this the correct choice for the patient’s reported insulin administration.
