1. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

Correct answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.

2. The client has atrial fibrillation and is receiving warfarin (Coumadin) therapy. Which laboratory test should be monitored to evaluate the effectiveness of the warfarin therapy?

Correct answer: A

Rationale: Monitoring the Prothrombin time (PT) and international normalized ratio (INR) is crucial for assessing the effectiveness of warfarin therapy. These tests help determine the clotting ability of the blood and ensure that the client is within the desired therapeutic range to prevent clotting events or bleeding complications. Activated partial thromboplastin time (aPTT) (Choice B) is more commonly used to monitor heparin therapy, not warfarin. Complete blood count (CBC) (Choice C) and fibrinogen levels (Choice D) do not directly assess the effectiveness of warfarin therapy in the same way that PT and INR do.

3. The patient with a history of myocardial infarction (MI) is prescribed aspirin. What instruction should the nurse include in the discharge teaching?

Correct answer: A

Rationale: Taking aspirin with food is recommended to prevent gastrointestinal irritation and upset, which are common side effects of aspirin. It helps protect the stomach lining and reduce the risk of developing ulcers. This instruction is crucial in promoting medication adherence and minimizing discomfort for the patient. Choices B, C, and D are incorrect because discontinuing aspirin without consulting a healthcare provider, taking it at bedtime, or avoiding it if taking other NSAIDs can have negative consequences on the patient's health and treatment plan.

4. The client with a history of left-sided heart failure is exhibiting increasing shortness of breath and frothy sputum. What is the priority nursing action?

Correct answer: A

Rationale: Shortness of breath and frothy sputum are indicative of pulmonary edema, a serious condition that requires immediate intervention to improve oxygenation. Administering oxygen is the priority action to support the client's respiratory function and prevent further deterioration. Oxygen therapy helps increase the oxygen levels in the blood, alleviate respiratory distress, and support vital organ function. Prompt intervention with oxygen can help stabilize the client while further assessments and treatments are initiated. Encouraging coughing and deep breathing may worsen the client's condition by increasing respiratory effort. Placing the client in a supine position can further compromise breathing in a client with pulmonary edema. Notifying the healthcare provider is important but not the priority when the client's respiratory status is deteriorating.

5. The client with diabetes mellitus has gangrene of the toes to the midfoot. Which goal should be included in this client's plan of care?

Correct answer: B

Rationale: Preventing infection is crucial in clients with gangrene to halt the spread of infection and avert further complications. Infections can exacerbate tissue damage and lead to systemic complications, making infection prevention a priority in the care plan for this client. Restoring skin integrity and promoting healing may not be achievable goals until the infection is under control. Improving nutrition is important for overall health but may not be the priority when the immediate concern is preventing infection.
