Which scheduled morning medication should the nurse withhold and not administer on the morning of surgery?

Metformin

Metoprolol

Prednisone

Levothyroxine

Answer and Explanation

The Correct Answer is A

Choice A rationale
Metformin is an oral antidiabetic medication that is typically withheld on the morning of surgery due to the risk of lactic acidosis, especially if the surgery involves the use of contrast dye.
Choice B rationale
Metoprolol is a beta-blocker used to treat hypertension and other heart conditions. It is typically continued up to and including the day of surgery to maintain heart rate and blood pressure control.
Choice C rationale
Prednisone is a corticosteroid medication. If a patient is on long-term corticosteroid therapy, it is typically continued on the day of surgery to prevent adrenal insufficiency.
Choice D rationale
Levothyroxine is a thyroid hormone replacement medication. It is typically continued on the day of surgery to maintain thyroid hormone levels.

Correct Answer is A

Explanation

Choice A rationale
Misoprostol is a medication that can help protect the stomach lining and reduce the risk of gastric irritation and ulcers caused by NSAIDs.
Choice B rationale
Ranitidine is a type of antacid that can help reduce stomach acid and relieve symptoms of heartburn, but it does not specifically protect the stomach lining from the effects of NSAIDs.
Choice C rationale
Sucralfate is a medication that can help treat and prevent ulcers in the stomach and intestines, but it does not specifically protect the stomach lining from the effects of NSAIDs.
Choice D rationale
Esomeprazole is a proton pump inhibitor that can reduce stomach acid and relieve symptoms of gastroesophageal reflux disease (GERD), but it does not specifically protect the stomach lining from the effects of NSAIDs. Prednisone Prednisone Explore

A. Hyponatremia B. Hypermagnesemia C. Hypokalemia D. Hypercalcemia .

Correct Answer is B

Explanation

Choice A rationale
Hyponatremia, or low sodium levels, is not typically associated with the use of milk of magnesia. Milk of magnesia works by drawing water into the intestines, which can help to soften the stool and stimulate bowel movements. While it can affect fluid balance, it does not directly affect sodium levels in the body.
Choice B rationale
This choice is correct. Milk of magnesia contains magnesium and can lead to hypermagnesemia, or high magnesium levels, if taken in excess or if the client has impaired kidney function. Hypermagnesemia can cause various symptoms, including nausea, vomiting, low blood pressure, and in severe cases, heart arrhythmias and cardiac arrest.
Choice C rationale
Hypokalemia, or low potassium levels, is not typically associated with the use of milk of magnesia. While milk of magnesia can affect fluid and electrolyte balance, it does not directly affect potassium levels in the body.
Choice D rationale
Hypercalcemia, or high calcium levels, is not typically associated with the use of milk of magnesia. Milk of magnesia does not contain calcium, so it would not contribute to an increase in calcium levels in the body.
