Nursing Elites

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. The healthcare professional is assisting in the care of a client diagnosed with deep vein thrombosis (DVT). Which instruction should be reinforced to prevent complications?

• A. Elevate the affected leg using pillows.
• B. Perform leg exercises while sitting.
• C. Wear snug compression stockings.
• D. Avoid applying ice packs to injuries.

Correct answer: A

Rationale: Elevating the affected leg using pillows is crucial in managing deep vein thrombosis (DVT) as it helps reduce swelling and promote venous return, thereby decreasing the risk of complications such as pulmonary embolism. This position aids in improving blood circulation and preventing blood clots from forming or worsening in the affected leg. Performing leg exercises while sitting might increase the risk of dislodging a blood clot. While snug compression stockings are beneficial, the primary focus should be on elevation. Avoiding ice packs on injuries is unrelated to DVT management.

3. The nurse is preparing a client for discharge after a myocardial infarction (MI). Which instruction is most important for the nurse to reinforce with the client?

• A. Avoid engaging in sexual activity for at least 6 weeks.
• B. Engage in moderate physical activity daily.
• C. Take prescribed medications even if you feel well.
• D. Return to work only when medically cleared.

Correct answer: C

Rationale: The most critical instruction for a client after a myocardial infarction is to continue taking prescribed medications even if they feel well. This is essential in preventing another myocardial infarction or other complications. Discontinuing medications prematurely can be detrimental to the client's recovery and may increase the risk of further cardiovascular events. Choices A, B, and D are incorrect because engaging in sexual activity, physical activity, or returning to work are important aspects of the client's recovery, but not as crucial as ensuring medication compliance to prevent further cardiac issues.

4. A client has a new prescription for digoxin. Which of the following instructions should the nurse include during discharge teaching?

• A. Take the medication with food.
• B. Monitor heart rate daily.
• C. Avoid consuming grapefruit juice.
• D. Increase intake of potassium-rich foods.

Correct answer: B

Rationale: The correct answer is B: 'Monitor heart rate daily.' When a client is prescribed digoxin, it is essential to monitor heart rate daily because digoxin can cause bradycardia, a condition characterized by a slow heart rate. Monitoring the heart rate regularly allows the client to promptly identify any signs of bradycardia and seek medical attention if needed. Choices A, C, and D are incorrect because taking digoxin with food, avoiding grapefruit juice, and increasing potassium-rich foods are not specific instructions related to managing the side effects or monitoring parameters of digoxin therapy.

5. A client with chronic obstructive pulmonary disease (COPD) is prescribed a metered-dose inhaler (MDI) with a spacer. Which instruction should the nurse reinforce to ensure correct use?

• A. Inhale deeply and slowly after activating the MDI.
• B. Hold the breath for 5 seconds after inhaling the medication.
• C. Rinse the mouth immediately after using the MDI.
• D. Exhale fully before placing the mouthpiece in the mouth.

Correct answer: A

Rationale: Inhaling deeply and slowly after activating the MDI is the correct instruction to ensure effective delivery of the medication to the lungs. This technique helps the medication reach the lower airways where it can be most beneficial in managing COPD symptoms. Inhaling too quickly or not deeply enough may result in improper drug delivery and reduce the effectiveness of the treatment. Holding the breath for 5 seconds after inhaling the medication (Choice B) may not be necessary and could cause discomfort without additional benefits. Rinsing the mouth immediately after using the MDI (Choice C) is not necessary unless specified by the healthcare provider. Exhaling fully before placing the mouthpiece in the mouth (Choice D) is not ideal as it may result in inadequate medication delivery to the lungs.
