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 potassium infusion rate is too rapid.

Another formulation of potassium should be given IV.

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

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

Answer and Explanation

The Correct Answer is A

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.

Correct Answer is B

Explanation

Pruritus is a common adverse effect of morphine administered via continuous epidural infusion. It is caused by the release of histamine from mast cells in the skin. Pruritus can be treated with antihistamines or opioid antagonists. Choice A is wrong because gastric bleeding is not a common adverse effect of morphine administered via continuous epidural infusion.

Gastric bleeding can occur due to peptic ulcer disease, nonsteroidal anti inflammatory drugs (NSAIDs), or anticoagulants.

Choice C is wrong because cough is not a common adverse effect of morphine administered via continuous epidural infusion.

Cough can be caused by respiratory infections, asthma, or chronic obstructive pulmonary disease (COPD).

Choice D is wrong because tachypnea is not a common adverse effect of morphine administered via continuous epidural infusion.

Tachypnea can be caused by hypoxia, anxiety, pain, or fever. Morphine can cause respiratory depression, which is characterized by bradypnea, not tachypnea.

A. Decrease in protein. B. Increase in BP. C. Oxygen saturation 96%. D. PaCO2, 30 mm Hg.

Correct Answer is B

Explanation

Albumin is a protein that helps maintain fluid balance in the body by drawing water into the blood vessels. Albumin infusion can increase the blood volume and blood pressure in patients who are in shock due to fluid loss or sepsis.

Choice A is wrong because albumin infusion does not decrease protein levels in the body.

Albumin is a protein itself and adding it to the blood increases the protein concentration.

Choice C is wrong because oxygen saturation of 96% is normal and does not indicate any improvement or deterioration in the patient’s condition.

Choice D is wrong because PaCO2 of 30 mm Hg is low and indicates respiratory alkalosis, which can be caused by hyperventilation, fever, or anxiety. Albumin infusion does not affect PaCO2 levels directly.
