A client is prescribed calcium carbonate for GERD.
After reviewing the client’s chart, which potential risk does the nurse identify for the client?
Hypercalcemia
Metabolic Alkalosis
Hepatotoxicity
Hyperphosphatemia
The Correct Answer is A
Choice A rationale
This choice is correct. Calcium carbonate, which is used to treat GERD, can lead to hypercalcemia, or high levels of calcium in the blood, if taken in excess or if the client has impaired kidney function. Hypercalcemia can cause various symptoms, including nausea, vomiting, constipation, and abdominal pain. It can also affect the nervous system, leading to confusion, lethargy, and fatigue. In severe cases, it can cause cardiac arrhythmias.
Choice B rationale
Metabolic alkalosis is a condition characterized by a high level of bicarbonate in the blood, leading to an increase in blood pH. While antacids like calcium carbonate can potentially cause metabolic alkalosis if taken in large amounts, it is less likely to occur in patients taking the medication for GERD, as the medication is used to neutralize stomach acid. Therefore, while it’s a potential risk, it’s less likely than hypercalcemia.
Choice C rationale
Hepatotoxicity, or liver damage, is not typically associated with the use of calcium carbonate. This medication does not have a direct effect on the liver, so it’s unlikely to cause hepatotoxicity unless the client has an underlying liver condition or is taking other medications that can cause liver damage.
Choice D rationale
Hyperphosphatemia, or high levels of phosphate in the blood, is not typically a risk associated with the use of calcium carbonate. In fact, calcium carbonate can bind to phosphate in the gut and reduce phosphate absorption, which can help manage high phosphate levels in certain conditions. Therefore, this choice is not the most likely risk for the client.

Correct Answer is B
Explanation
Choice A rationale
This choice suggests that the nurse would administer 4.5 units of insulin for the carbohydrates consumed. However, this is not accurate. The carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This choice underestimates the amount of insulin needed, which could lead to hyperglycemia, or high blood sugar.
Choice B rationale
This choice is correct. The client’s carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This amount of insulin would help to properly metabolize the carbohydrates consumed and maintain the client’s blood sugar within the target range.
Choice C rationale
This choice suggests that the nurse would administer 6.2 units of insulin for the carbohydrates consumed. However, this is not accurate. The carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This choice overestimates the amount of insulin needed, which could lead to hypoglycemia, or low blood sugar.
Choice D rationale
This choice suggests that the nurse would administer 7.1 units of insulin for the carbohydrates consumed. However, this is not accurate. The carbohydrate ratio is 1:10, meaning 1 unit of insulin is needed for every 10 grams of carbohydrates. The client consumed 57 grams of carbohydrates (45g from rice + 12g from broccoli). Therefore, the calculation would be 57g ÷ 10 = 5.7 units of insulin. This choice significantly overestimates the amount of insulin needed, which could lead to hypoglycemia, or low blood sugar.
Correct Answer is B
Explanation
Choice A rationale
Digoxin is a cardiac glycoside used to treat heart failure and atrial fibrillation. While it’s important to monitor digoxin levels in patients receiving gentamicin due to the risk of increased digoxin levels, it’s not the most concerning medication.
Choice B rationale
Furosemide is a loop diuretic that can cause ototoxicity, especially when used with aminoglycosides like gentamicin. Therefore, this is the medication the nurse should be most concerned about.
Choice C rationale
Prednisolone is a corticosteroid medication. While it’s important to monitor for potential interactions, it’s not the most concerning medication in this context.
Choice D rationale
Warfarin is an anticoagulant medication. While it’s important to monitor for potential interactions, it’s not the most concerning medication in this context.
