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 LPN/LVN is reinforcing discharge instructions to a client who has been prescribed nitroglycerin sublingual tablets for angina. Which statement by the client indicates a need for further teaching?

• A. I will keep my nitroglycerin tablets in the original glass bottle.
• B. I will sit or lie down when I take a nitroglycerin tablet.
• C. I will take a nitroglycerin tablet every 5 minutes if chest pain persists, up to a total of 3 tablets.
• D. I can swallow the nitroglycerin tablet with a glass of water if it does not dissolve quickly.

Correct answer: D

Rationale: The correct answer is D. Nitroglycerin sublingual tablets should not be swallowed; they must dissolve under the tongue to be effective. Choice A is correct as nitroglycerin tablets should be stored in their original glass container to prevent degradation. Choice B is correct as sitting or lying down when taking a nitroglycerin tablet helps prevent dizziness or fainting due to a sudden drop in blood pressure. Choice C is correct as taking a nitroglycerin tablet every 5 minutes for a maximum of 3 tablets is the correct protocol for managing angina symptoms.

3. A nurse is providing teaching to a client who has a new prescription for warfarin. Which of the following statements should the nurse 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 B: 'Report any signs of bleeding.' When a patient is prescribed warfarin, it is essential to monitor for signs of bleeding as warfarin is an anticoagulant that increases the risk of bleeding. Choices A, C, and D are incorrect. Avoid using a soft toothbrush is not directly related to warfarin therapy, increasing the intake of leafy green vegetables can interfere with warfarin's effectiveness due to its vitamin K content, and taking warfarin with food is unnecessary as it can be taken with or without food.

4. A client with chronic stable angina is prescribed nitroglycerin (Nitrostat) for chest pain. The nurse should include which instruction when teaching the client about this medication?

• A. Take nitroglycerin at the first sign of chest pain.
• B. Swallow the tablet whole with water.
• C. Take nitroglycerin with meals to prevent stomach upset.
• D. Store nitroglycerin in a cool, dry place.

Correct answer: A

Rationale: The correct instruction when teaching a client about nitroglycerin (Nitrostat) is to take it at the first sign of chest pain. Nitroglycerin works rapidly to dilate blood vessels, improving blood flow to the heart muscle. Taking it promptly can help alleviate symptoms quickly and prevent the condition from worsening. Choice B is incorrect because nitroglycerin is usually taken sublingually (under the tongue) and not swallowed. Choice C is incorrect because nitroglycerin is not typically taken with meals. Choice D is incorrect because nitroglycerin should be stored in its original container away from heat and light.

5. The nurse is planning measures to decrease the incidence of chest pain for a client with angina pectoris. What intervention should the nurse do to effectively accomplish this goal?

• A. Provide a quiet and low-stimulus environment.
• B. Encourage the family to visit very frequently.
• C. Encourage the client to call friends and relatives each day.
• D. Recommend that the client watch TV as a constant diversion.

Correct answer: A

Rationale: The correct answer is A: Provide a quiet and low-stimulus environment. A calm and quiet environment can help reduce stress, which is beneficial in preventing the occurrence of chest pain in clients with angina. Choice B is incorrect because excessive or frequent visitations may lead to increased stress and agitation for the client. Choice C is incorrect as it may not always contribute to a calm environment and could potentially increase the client's stress levels. Choice D is inappropriate as watching TV constantly may not promote a quiet and low-stimulus environment, which is essential in managing angina pectoris.
