A nurse is caring for a client who has breast cancer and reports pain 1 hr after administration of prescribed morphine 10 mg IV.
Which of the following medications should the nurse expect to administer?

Fentanyl transmucosal.

Lidocaine patch.

Morphine tablet.

Naloxone IV.

Answer and Explanation

The Correct Answer is A

This is because fentanyl transmucosal is a fast-acting opioid that can be used for breakthrough pain in patients who are already receiving opioids for chronic pain. Breakthrough pain is a sudden and severe increase in pain that occurs despite the use of regular pain medication. Fentanyl transmucosal has a rapid onset of action (1-3 minutes) and a short duration of effect (1-2 hours), which makes it suitable for treating episodic pain.

Choice B. Lidocaine patch is wrong because lidocaine patch is a topical anesthetic that can be used for localized neuropathic pain, but not for acute or severe pain.

Choice C. Morphine tablet is wrong because morphine tablet is a long-acting opioid that can be used for chronic pain, but not for breakthrough pain. Morphine tablet has a slow onset of action (30-60 minutes) and a long duration of effect (3-4 hours), which makes it unsuitable for treating episodic pain.

Choice D. Naloxone IV is wrong because naloxone IV is an opioid antagonist that can reverse the effects of opioids, but not relieve pain.

Naloxone IV can cause

Correct Answer is A

Explanation

The correct sequence for mixing regular insulin and NPH insulin in the same syringe is important to ensure proper dosing. The nurse should follow these steps:

Inject air into the NPH (intermediate-acting) insulin vial: Injecting air into the NPH vial first helps to equalize the pressure in the vial, making it easier to withdraw the insulin later. This step is done first to avoid contaminating the regular insulin vial with NPH insulin.
Inject air into the regular insulin vial: Next, inject an amount of air equal to the intended regular insulin dose into the regular insulin vial.This also helps to equalize the pressure and makes it easier to withdraw the insulin.
Withdraw the regular insulin from the vial: The nurse should withdraw the regular insulin first because it is clear and not contaminated. This prevents any NPH insulin from mixing into the regular insulin vial.
Withdraw the regular insulin from the vial: Finally, the nurse withdraws the NPH insulin. Since the regular insulin has already been drawn up, there is no risk of contaminating the regular insulin with NPH insulin.

This sequence ensures that you don't contaminate the vials, and you accurately withdraw the appropriate doses of each insulin type.

A. The potassium infusion rate is too rapid. B. Another formulation of potassium should be given IV. C. Potassium chloride should be diluted in dextrose 5% in water. D. The client should be treated by giving potassium by IV bolus.

Correct Answer is A

Explanation

According to various guidelines12345, the recommended rate of intravenous potassium replacement is 10-20 mEq/h with continuous ECG monitoring. The maximum rate is 40 mEq/h in emergency situations. The prescription given by the provider exceeds this limit and could cause cardiac arrhythmias or hyperkalemia.

Choice B is wrong because potassium chloride is a common and appropriate formulation of potassium for intravenous administration.

Choice C is wrong because potassium chloride should not be diluted in dextrose 5% in water, as this could cause hyperglycemia or osmotic diuresis.

Choice D is wrong because potassium should never be given by IV bolus, as this could cause cardiac arrest or tissue necrosis.
