1. The healthcare provider notes this rhythm on the client's cardiac monitor. The healthcare provider next reports that the client is experiencing which heart rhythm?

Correct answer: B

Rationale: The correct answer is B, Atrial fibrillation. Atrial fibrillation is characterized by an irregular and often rapid heart rate, which can lead to poor blood flow due to ineffective contractions of the atria. Sinus bradycardia (Choice C) is a regular but slow heart rhythm originating from the sinus node. Normal sinus rhythm (Choice A) refers to a regular heartbeat originating from the sinus node. Ventricular fibrillation (Choice D) is a life-threatening arrhythmia characterized by rapid, uncoordinated contractions of the ventricles.

2. The client is receiving digoxin (Lanoxin) for heart failure. Which symptom would indicate digoxin toxicity?

Correct answer: B

Rationale: Yellow or blurred vision can be a sign of digoxin toxicity. These visual disturbances are concerning as they indicate a potential adverse reaction to the medication. Recognizing this symptom promptly is crucial to prevent serious complications. Increased appetite, increased urination, and diarrhea are not typically associated with digoxin toxicity. Therefore, option B is the correct choice in this scenario.

3. Why should the client diagnosed with rheumatic heart disease be advised to notify the dentist before dental procedures?

Correct answer: A

Rationale: Clients with rheumatic heart disease are at risk for infective endocarditis, a serious infection of the heart lining or valves. They need prophylactic antibiotics before invasive procedures, including dental work, to prevent this life-threatening complication. While dysrhythmias with high-speed drills, adverse reactions to local anesthesia, and the risk of heart failure during stressful events are all concerns for clients with heart conditions, the primary reason for notifying the dentist before dental procedures in rheumatic heart disease is the need for prophylactic antibiotics to prevent infective endocarditis.

4. A healthcare professional is assessing a client who has been taking isoniazid to treat tuberculosis. The healthcare professional should monitor the client for which of the following findings as an adverse effect of the medication?

Correct answer: D

Rationale: Correct. Jaundice is a serious adverse effect of isoniazid due to liver damage. It is essential to monitor for signs of liver toxicity, such as jaundice, while the client is on this medication. Diarrhea is a common side effect of isoniazid, but it is not as serious as liver damage. Blurred vision and hearing loss are not typically associated with isoniazid use.

5. A client receives discharge teaching for a new prescription of lithium. Which instruction should be included?

Correct answer: B

Rationale: The correct instruction to include when a client receives discharge teaching for a new prescription of lithium is to increase their intake of sodium. Lithium can lead to decreased sodium levels, putting the individual at risk of developing hyponatremia. By increasing sodium intake, the client can counteract this risk, maintain a proper sodium balance, and prevent complications. Choices A, C, and D are incorrect because taking lithium with food, monitoring for signs of hypercalcemia, and avoiding dairy products are not directly related to managing the side effects or risks associated with lithium therapy.
