Nursing Elites

1. A client with a history of angina pectoris complains of substernal chest pain. The nurse checks the client's blood pressure and administers nitroglycerin 0.4 mg sublingually. Five minutes later, the client is still experiencing chest pain. What is the next appropriate nursing action?

• A. Administer another dose of nitroglycerin.
• B. Notify the healthcare provider immediately.
• C. Have the client lie down and stay calm.
• D. Give the client aspirin 325 mg to chew.

Correct answer: A

Rationale: If chest pain persists after the first dose of nitroglycerin, it is appropriate to administer a second dose while continuing to monitor the client's response. Nitroglycerin is a vasodilator commonly used to relieve angina symptoms by dilating blood vessels and increasing blood flow to the heart. Reassessing the client's response and providing a second dose may be necessary to achieve adequate pain relief and improve blood flow to the heart. Administering another dose of nitroglycerin is the next appropriate step in managing angina symptoms. Notifying the healthcare provider immediately (Choice B) may be necessary if the client's condition worsens or if there are other concerning symptoms. Having the client lie down and stay calm (Choice C) is generally recommended but addressing the ongoing chest pain takes precedence. Giving the client aspirin 325 mg to chew (Choice D) is beneficial for suspected myocardial infarction but is not the immediate action indicated for persistent angina symptoms.

2. 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.

3. A client has just completed an information session about measures to minimize the progression of coronary artery disease (CAD). Which statement indicates an initial understanding of lifestyle alterations?

• A. I should take daily medication for life.
• B. I should eat a diet that is low in fat and cholesterol.
• C. I should continue to smoke to keep the metabolic rate high.
• D. I should begin to exercise if the diet is not sufficient to achieve weight loss.

Correct answer: B

Rationale: Choosing a diet that is low in fat and cholesterol is crucial for managing and preventing the progression of coronary artery disease (CAD). This dietary change can help reduce the risk of further complications associated with CAD, such as plaque buildup in the arteries. It is a fundamental lifestyle alteration that can positively impact the client's heart health. Option A is incorrect as relying solely on medication without lifestyle changes may not address the root cause of CAD. Option C is incorrect as smoking is harmful and worsens CAD. Option D is incorrect because exercise is a crucial part of a healthy lifestyle, but dietary changes should come first in managing CAD.

4. The client has been prescribed atorvastatin (Lipitor) for hyperlipidemia. Which instruction should the nurse provide to the client?

• A. Take the medication in the morning with breakfast.
• B. Avoid drinking grapefruit juice while taking this medication.
• C. Increase your intake of dietary fiber while on this medication.
• D. Avoid eating foods high in potassium.

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client prescribed atorvastatin (Lipitor) for hyperlipidemia is to avoid drinking grapefruit juice while taking this medication. Grapefruit juice can interfere with the metabolism of atorvastatin, leading to an increased risk of side effects. It is crucial for the client to adhere to this instruction to ensure the effectiveness and safety of the treatment. Choices A, C, and D are incorrect because taking the medication with breakfast, increasing dietary fiber intake, and avoiding foods high in potassium are not specific instructions related to atorvastatin therapy for hyperlipidemia.

5. The LPN/LVN is reinforcing instructions to a client on the use of a metered-dose inhaler. The nurse should recognize that the client is using the inhaler correctly if the client takes which action?

• A. Takes a deep breath and then exhales just before administration
• B. Holds the mouthpiece 1 to 2 inches from the mouth
• C. Inhales the medication and then exhales immediately after administration
• D. Performs 3 short inhalations and then exhales deeply after administration

Correct answer: A

Rationale: When using a metered-dose inhaler, the client should take a deep breath and then exhale just before administration. This technique helps ensure that the medication is inhaled effectively. By exhaling before administration, the client can fully inhale the medication into the lungs, maximizing its therapeutic effects. Choice B is incorrect because holding the mouthpiece 1 to 2 inches from the mouth is not a crucial step for using a metered-dose inhaler correctly. Choice C is incorrect because inhaling the medication and then exhaling immediately after administration would not allow the medication to be adequately absorbed into the lungs. Choice D is incorrect because performing 3 short inhalations and then exhaling deeply after administration is not the correct technique for using a metered-dose inhaler.
