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 and is monitoring the client for cardiac changes indicative of hypokalemia. Which occurrence noted on the cardiac monitor indicates the presence of hypokalemia?
- A. Tall, peaked T waves
- B. ST-segment depression
- C. Prolonged P-R interval
- D. Widening of the QRS complex
Correct answer: B
Rationale: ST-segment depression can indicate hypokalemia, affecting the heart's electrical conduction. Hypokalemia leads to alterations in the repolarization phase of the cardiac action potential, resulting in ST-segment depression on the ECG. Tall, peaked T waves are indicative of hyperkalemia, not hypokalemia. A prolonged P-R interval is more commonly associated with first-degree heart block. Widening of the QRS complex is typically seen in conditions like bundle branch blocks or ventricular tachycardia, not specifically in hypokalemia.
3. The healthcare provider is preparing to administer a calcium channel blocker to a client with hypertension. What parameter should be checked before administering the medication?
- A. Apical pulse
- B. Serum calcium level
- C. Blood pressure
- D. Respiratory rate
Correct answer: C
Rationale: Before administering a calcium channel blocker to a client with hypertension, the healthcare provider should check the client's blood pressure. Calcium channel blockers are used to lower blood pressure, making it essential to assess the current blood pressure to ensure it is within the appropriate range for administration. Checking the apical pulse (choice A) is not the priority before administering a calcium channel blocker, as the focus should be on blood pressure. Serum calcium level (choice B) is not directly related to the administration of calcium channel blockers for hypertension. Respiratory rate (choice D) is not the primary parameter to check before administering a calcium channel blocker in this scenario.
4. What should be the nurse's priority action when a client diagnosed with angina pectoris complains of chest pain while taking a brisk walk?
- A. Administer nitroglycerin
- B. Have the client sit down
- C. Obtain an electrocardiogram
- D. Apply oxygen
Correct answer: B
Rationale: The nurse's priority action when a client diagnosed with angina pectoris complains of chest pain while taking a brisk walk is to have the client sit down. Sitting down reduces the workload on the heart and may alleviate pain by improving oxygen supply. This action aims to reduce the strain on the heart and improve oxygen delivery to the myocardium, which can help relieve the symptoms of angina pectoris. Administering nitroglycerin could be the next step after having the client sit down if the pain persists. Obtaining an electrocardiogram and applying oxygen are not the immediate priority actions when dealing with angina pectoris symptoms.
5. A client has a new prescription for docusate sodium. Which of the following instructions should be included in the discharge teaching?
- A. Take the medication with a full glass of water.
- B. Take the medication at bedtime.
- C. Take the medication on an empty stomach.
- D. Avoid taking the medication with antacids.
Correct answer: A
Rationale: Corrected Rationale: When taking docusate sodium, it is important to take the medication with a full glass of water to help ensure its proper effectiveness. This helps prevent the stool from hardening and makes it easier to pass, especially for individuals experiencing constipation. Choice B is incorrect because there is no specific instruction to take docusate sodium at bedtime. Choice C is incorrect because docusate sodium does not need to be taken on an empty stomach. Choice D is incorrect because there is no need to avoid taking docusate sodium with antacids.
