A patient with atrial fibrillation and a serum potassium level of 3.0 mEq/L takes digoxin (Lanoxin), ASA (aspirin), KCL (potassium chloride), and warfarin (Coumadin) daily. The patient reports visual disturbances. The nurse suspects problems with which medication?
Potassium chloride.
Warfarin.
Aspirin.
Digoxin.
The Correct Answer is D
Digoxin. Choice A rationale:
Potassium chloride (KCL) is a supplement used to treat or prevent low potassium levels. While it can have side effects, visual disturbances are not typically associated with KCL. Therefore, it is not the medication the nurse suspects to be causing the problem.
Choice B rationale:
Warfarin (Coumadin) is an anticoagulant used to prevent blood clot formation. Visual disturbances are not a known side effect of warfarin. Therefore, it is unlikely to be the cause of the patient's symptoms.
Choice C rationale:
Aspirin (ASA) is a pain reliever and antiplatelet medication, and while it can cause visual disturbances in some cases, it is not a common or significant side effect. Aspirin is also not specifically linked to atrial fibrillation.
Choice D rationale:
Digoxin (Lanoxin) is used to treat atrial fibrillation and heart failure. Visual disturbances are a known side effect of digoxin toxicity. Given the patient's diagnosis of atrial fibrillation and the reported symptoms, the nurse suspects the problem lies with digoxin and should further investigate and report to the provider.

Correct Answer is B
Explanation
Metabolic alkalosis.
Choice A rationale:
The given blood gas results show a pH of 7.53, which is alkaline (above the normal range of
7.35 to 7.45), and a high bicarbonate level of 36 mEq/L (normal range is 22 to 26 mEq/L). This combination indicates metabolic alkalosis, a condition where there is an excessive accumulation of bicarbonate in the blood, leading to increased pH.
Choice B rationale:
Metabolic alkalosis is characterized by increased blood bicarbonate levels, which can occur due to conditions like vomiting, diuretic use, or excessive ingestion of bicarbonate-containing substances. It results in symptoms such as muscle twitching, tetany, and respiratory depression.
Choice C rationale:
Respiratory alkalosis is characterized by an elevated blood pH and low carbon dioxide levels (hypocapnia). However, the bicarbonate level is not directly related to respiratory alkalosis, making this choice incorrect based on the given information.
Choice D rationale:
Metabolic acidosis is characterized by a decreased blood pH and low bicarbonate levels. The presented blood gas results show an alkaline pH and high bicarbonate, making this choice incorrect.
Correct Answer is A
Explanation
The correct answer is choice A. Client has an NG tube to gastric suction.
Choice A rationale:
Having an NG tube to gastric suction can lead to hypokalemia because the suctioning process removes potassium from the stomach contents, leading to a decrease in serum potassium levels.
Choice B rationale:
While a history of alcohol abuse disorder can lead to various electrolyte imbalances, it is not the most direct cause of hypokalemia compared to gastric suction.
Choice C rationale:
Drinking 3.5 to 4 liters of water each day can lead to dilutional hyponatremia but is less likely to cause hypokalemia directly.
Choice D rationale:
Spironolactone is a potassium-sparing diuretic, which means it helps retain potassium in the body. Therefore, it is not a causative factor for hypokalemia.
