A nurse is caring for a client who is to receive potassium replacement. The provider's prescription reads, "Potassium chloride 30 mEq in 0.9% sodium chloride 100 mL IV over 30 min." For which of the following reasons should the nurse clarify this prescription with the provider?

The client should be treated by giving potassium by IV bolus.

Another formulation of potassium should be given IV.

Potassium chloride should be diluted in dextrose 5% in water.

The potassium infusion rate is too rapid.

Answer and Explanation

The Correct Answer is D

Choice A rationale:

IV bolus administration of potassium is not appropriate due to the risk of cardiac arrhythmias.

Choice B rationale:

The formulation of potassium (potassium chloride) is appropriate for IV administration.

Choice C rationale:

Potassium chloride is typically diluted in normal saline (0.9% sodium chloride) for IV administration, not dextrose.

Choice D rationale:

The prescribed infusion rate of 30 mEq of potassium chloride over 30 minutes is too rapid and could lead to adverse effects, such as cardiac arrhythmias. The nurse should clarify the prescription and discuss a slower infusion rate with the provider.

Correct Answer is B

Explanation

Choice A rationale:

Weight gain is not typically associated with fluid volume deficit.

Choice B rationale:

Oliguria (reduced urine output) is indicative of fluid volume deficit, as the body conserves fluid by producing less urine.

Choice C rationale:

Nausea may be related to various factors, but it is not a specific sign of fluid volume deficit.

Choice D rationale:

Headaches can occur for various reasons and are not specific to fluid volume deficit.

A. Morphine tablet B. Fentanyl transmucosa C. Lidocaine patch D. Naloxone IV

Correct Answer is B

Explanation

Choice A rationale:

Morphine tablet is not likely to provide rapid relief within 1 hour for moderate to severe pain.

Choice B rationale:

Fentanyl transmucosa, such as a fentanyl lozenge or transmucosal patch, is a strong opioid analgesic that can provide rapid relief for breakthrough pain.

Choice C rationale:

A lidocaine patch is typically used for localized pain relief and might not provide the desired level of relief for systemic pain.

Choice D rationale:

Naloxone IV is an opioid antagonist used to reverse opioid overdose. It would not be appropriate to administer naloxone in this situation.
