ATI RN Exit Exam Test Bank

Correct Answer: B

Rationale: Digoxin is commonly prescribed to manage atrial fibrillation by controlling heart rate. While Warfarin is used to prevent blood clots, it is not primarily used for controlling heart rate in atrial fibrillation. Aspirin is not the first-line treatment for atrial fibrillation and is generally not recommended for rhythm control. Lisinopril is an ACE inhibitor used to treat high blood pressure and heart failure, but it is not typically prescribed as the primary medication for managing atrial fibrillation.

Correct Answer: B

Rationale: The correct instruction for a client taking digoxin is to notify their provider if they experience visual disturbances. Visual disturbances can be a sign of digoxin toxicity, and prompt notification to the healthcare provider is essential for timely intervention. Choice A is incorrect because digoxin should be taken on an empty stomach for better absorption. Choice C is incorrect because antacids can interfere with the absorption of digoxin. Choice D is incorrect because a heart rate less than 60/min is not a sole reason to avoid taking digoxin; rather, it is important to monitor the heart rate and consult with the healthcare provider if there are concerns.

Correct Answer: A

Rationale: The correct answer is A: Hypokalemia. Furosemide, a loop diuretic, commonly causes the loss of potassium in the urine, leading to hypokalemia. This electrolyte imbalance can result in various complications such as cardiac arrhythmias and muscle weakness. Choice B, Hyponatremia, is not typically associated with furosemide use. Choice C, Hyperkalemia, is the opposite of the expected electrolyte imbalance caused by furosemide. Choice D, Hypercalcemia, is not a common side effect of furosemide.

Correct Answer: A

Rationale: Naloxone is the correct answer. Naloxone is specifically used to reverse the effects of opioid overdose by binding to opioid receptors and blocking the effects of opioids. Epinephrine is mainly used to treat severe allergic reactions, Atropine is used for certain types of heart conditions and to reduce salivation or respiratory secretions, and Lidocaine is a local anesthetic used for numbing purposes. Therefore, choices B, C, and D are incorrect in the context of reversing opioid overdose.

Correct Answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.
