Nursing Elites

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?

• A. Tall, peaked T waves
• B. ST segment depressions
• C. Shortened P-R intervals
• D. Shortening of the QRS complex

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 nurse is caring for a client receiving anticoagulant therapy. Which instruction should the nurse reinforce with the client to prevent bleeding complications?

• A. Use a soft-bristle toothbrush and electric razor.
• B. Increase your intake of vitamin K-rich foods.
• C. Take aspirin if you have a headache.
• D. Avoid using ice packs for injuries.

Correct answer: A

Rationale: The correct instruction to prevent bleeding complications in a client on anticoagulant therapy is to use a soft-bristle toothbrush and an electric razor. These implements help reduce the risk of bleeding by being gentle on the skin and reducing the chances of cuts or abrasions that could lead to bleeding in individuals on anticoagulants. Choice B is incorrect because increasing intake of vitamin K-rich foods can interfere with the action of anticoagulants. Choice C is incorrect as aspirin is a blood thinner and can increase the risk of bleeding when combined with anticoagulant therapy. Choice D is incorrect as ice packs can help reduce bleeding and swelling in injuries, but in a client on anticoagulant therapy, it is important to avoid potential trauma to the skin that could lead to bleeding.

3. The nurse is caring for a client with heart failure who is receiving digoxin (Lanoxin). Which sign of digoxin toxicity should the nurse monitor for?

• A. Hypertension
• B. Bradycardia
• C. Hyperglycemia
• D. Insomnia

Correct answer: B

Rationale: Corrected Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause bradycardia due to its effects on the heart's electrical conduction system. Monitoring for a slow heart rate is crucial as it indicates potential toxicity. Hypertension, hyperglycemia, and insomnia are not typically associated with digoxin toxicity. Hypertension is more commonly seen in other conditions, hyperglycemia is not a typical sign of digoxin toxicity, and insomnia is not a recognized symptom of digoxin toxicity.

4. The nurse is preparing to care for a client who will be arriving from the recovery room after an above-the-knee amputation. The nurse ensures that which priority item is available for emergency use?

• A. Surgical tourniquet
• B. Dry sterile dressings
• C. Incentive spirometer
• D. Over-the-bed trapeze

Correct answer: A

Rationale: In the case of an above-the-knee amputation, the priority item that should be available for emergency use is a surgical tourniquet. This is crucial to control severe bleeding that may occur post-operatively. Dry sterile dressings (choice B) are important for wound care but not for immediate post-operative emergencies like bleeding. An incentive spirometer (choice C) is used for respiratory exercises and not directly related to emergency management post-amputation. An over-the-bed trapeze (choice D) is used for assisting clients with mobility and positioning, not for emergency situations involving bleeding.

5. A healthcare provider is providing discharge instructions to a client who has a new prescription for warfarin. Which of the following statements should the healthcare provider include?

• A. Avoid using a soft toothbrush.
• B. Report any signs of bleeding.
• C. Increase your intake of leafy green vegetables.
• D. Take the medication with food.

Correct answer: B

Rationale: The correct answer is to instruct the client to report any signs of bleeding when taking warfarin. Warfarin is an anticoagulant medication that increases the risk of bleeding, so it is essential to monitor for any signs of abnormal bleeding and report them promptly for appropriate management. Choices A, C, and D are incorrect. Instructing the client to avoid using a soft toothbrush is not directly related to warfarin therapy. Increasing the intake of leafy green vegetables is not recommended as they contain vitamin K, which can interfere with warfarin's anticoagulant effects. Taking warfarin with food can be inconsistent and may not result in optimal absorption.
