The LPN/LVN is assisting in the care of a client with chronic heart failure who is receiving digoxin (Lanoxin). Which sign should the nurse monitor for that could indicate digoxin toxicity?

Correct Answer: A

Rationale: Bradycardia is a common sign of digoxin toxicity and should be closely monitored. Digoxin toxicity can lead to various cardiac dysrhythmias, with bradycardia being a significant indicator. Monitoring the client's heart rate is crucial to detect and manage digoxin toxicity promptly. Tachycardia, hypertension, and hyperglycemia are not typically associated with digoxin toxicity. Tachycardia is more commonly seen with inadequate treatment of heart failure, hypertension is a possible but less common effect, and hyperglycemia is not a typical sign of digoxin toxicity.

Correct Answer: B

Rationale: When a client with a history of angina pectoris reports chest pain unrelieved by nitroglycerin, it may indicate a myocardial infarction, also known as a heart attack. In this situation, the nurse should immediately notify the healthcare provider to ensure prompt evaluation and appropriate intervention. Delay in seeking medical attention for chest pain unrelieved by nitroglycerin can be life-threatening, as it might be a sign of a more serious cardiac event. Administering another dose of nitroglycerin (Choice A) without further evaluation can be risky, as the client's condition may require a different intervention. Having the client lie down and rest (Choice C) or encouraging deep breaths (Choice D) are not appropriate actions in this scenario where a more serious cardiac event needs to be ruled out.

Correct Answer: A

Rationale: The correct preoperative instruction that the LPN/LVN should reinforce to a client scheduled for a carotid endarterectomy is being NPO after midnight before the surgery. This instruction is essential to prevent aspiration and ensure a safe procedure. Avoiding oral intake helps reduce the risk of complications during anesthesia induction and the surgical process. Choices B, C, and D are incorrect because avoiding deep breathing and coughing, resuming normal eating and drinking, and taking all prescribed medications the morning of surgery are not recommended preoperative instructions for a carotid endarterectomy.

Correct Answer: A

Rationale: A weight gain of 2 pounds in 2 days is concerning in a client with heart failure as it can indicate fluid retention and worsening of the condition. This finding requires immediate medical attention to prevent further complications. Increased urination at night (choice B) may be due to various reasons like diuretic use and is not an immediate concern. Mild shortness of breath on exertion (choice C) is expected in clients with heart failure and may not require immediate reporting. Decreased appetite and fatigue (choice D) are common symptoms in heart failure but are not as urgent as sudden weight gain.

Correct Answer: A

Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.
