LPN Pharmacology
1. 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.
2. A client has a new prescription for furosemide. Which of the following instructions should the nurse include?
- A. Take the medication with or without food.
- B. Monitor for signs of hypokalemia.
- C. Increase your intake of potassium-rich foods.
- D. Expect an increase in urination.
Correct answer: D
Rationale: The correct instruction to include when a client is prescribed furosemide is to expect an increase in urination. Furosemide is a diuretic that works by increasing urine production, so it is essential for the client to anticipate and understand this effect. Monitoring for signs of hypokalemia and increasing potassium-rich foods are not directly related to furosemide use. Hypokalemia is a potential side effect of furosemide, so monitoring for it is crucial. Increasing potassium-rich foods can help counteract potassium loss due to diuretic use. Taking furosemide with food is not required, as it can be taken with or without food.
3. A client diagnosed with coronary artery disease (CAD) reports chest pain radiating to the left arm. 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 helps dilate blood vessels and improve blood flow to the heart, relieving chest pain associated with coronary artery disease. Reassessing the client's response to a second dose is crucial before considering other interventions like contacting the healthcare provider or providing additional medications. Administering another dose of nitroglycerin aligns with the standard protocol for managing ongoing chest pain in clients with CAD.
4. The nurse is reinforcing instructions to a client with coronary artery disease who is prescribed a low-cholesterol diet. The nurse should advise the client to choose which food item?
- A. Eggs and bacon
- B. Oatmeal with fresh fruit
- C. Cream of chicken soup
- D. Grilled cheese sandwich
Correct answer: B
Rationale: Oatmeal with fresh fruit is a suitable choice for a client with coronary artery disease on a low-cholesterol diet as it is low in cholesterol and provides heart-healthy benefits. Eggs and bacon, cream of chicken soup, and grilled cheese sandwich are higher in cholesterol and may not be as heart-healthy for this client. Eggs and bacon are high in cholesterol, cream of chicken soup may contain saturated fats, and a grilled cheese sandwich typically contains high amounts of fat and cholesterol, making them less suitable choices for a client with coronary artery disease on a low-cholesterol diet.
5. A client is admitted with coronary artery disease (CAD) and reports dyspnea at rest. What is the nurse's priority intervention?
- A. Elevate the head of the bed.
- B. Administer oxygen.
- C. Perform continuous ECG monitoring.
- D. Apply a nasal cannula.
Correct answer: A
Rationale: The nurse's priority intervention for a client with coronary artery disease (CAD) experiencing dyspnea at rest is to elevate the head of the bed. Elevating the head of the bed helps improve lung expansion and reduces the workload on the heart, aiding in respiratory effort and cardiac function. This intervention is crucial in enhancing oxygenation and optimizing cardiac output in individuals with CAD presenting with dyspnea. Administering oxygen (Choice B) is important but elevating the head of the bed takes precedence as it directly addresses the client's respiratory distress. Continuous ECG monitoring (Choice C) and applying a nasal cannula (Choice D) are relevant interventions but not the priority when a client with CAD reports dyspnea at rest.
