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. After a client with a history of myocardial infarction (MI) is prescribed aspirin, which instruction should the nurse include in the discharge teaching?

• A. Take the aspirin with food to prevent gastrointestinal upset
• B. Discontinue the aspirin if you experience ringing in your ears
• C. Take the aspirin at bedtime to minimize side effects
• D. Avoid taking aspirin if you are also taking other NSAIDs

Correct answer: A

Rationale: The correct instruction is to take aspirin with food to prevent gastrointestinal upset. Aspirin can irritate the stomach lining, leading to potential gastrointestinal issues. Taking it with food helps reduce this risk by providing a protective layer in the stomach. This is a common recommendation to minimize the risk of gastrointestinal side effects when taking aspirin. Choices B, C, and D are incorrect. Choice B is not a typical reason to discontinue aspirin, as ringing in the ears is not a common side effect of aspirin. Choice C does not have a direct correlation to minimizing side effects of aspirin. Choice D is inaccurate because while caution should be exercised when taking aspirin with other NSAIDs due to the increased risk of bleeding, it does not mean aspirin should be entirely avoided if other NSAIDs are being taken.

3. The client with diabetes mellitus has gangrene of the toes to the midfoot. Which goal should be included in this client's plan of care?

• A. Restore skin integrity.
• B. Prevent infection.
• C. Promote healing.
• D. Improve nutrition.

Correct answer: B

Rationale: Preventing infection is crucial in clients with gangrene to halt the spread of infection and avert further complications. Infections can exacerbate tissue damage and lead to systemic complications, making infection prevention a priority in the care plan for this client. Restoring skin integrity and promoting healing may not be achievable goals until the infection is under control. Improving nutrition is important for overall health but may not be the priority when the immediate concern is preventing infection.

4. A client is wearing a continuous cardiac monitor, which begins to alarm at the nurse's station. The nurse sees no electrocardiographic complexes on the screen. What should the nurse do first?

• A. Call a code blue.
• B. Call the healthcare provider.
• C. Check the client's status and lead placement.
• D. Press the recorder button on the ECG console.

Correct answer: C

Rationale: The correct first action for the nurse to take is to check the client's status and lead placement. This step is crucial to ensure that the alarm is not triggered by a simple issue such as lead displacement. Calling a code blue (choice A) is premature without assessing the client first. Contacting the healthcare provider (choice B) can be done after ruling out basic causes for the alarm. Pressing the recorder button (choice D) is not as urgent as checking the client's status and lead placement in this scenario.

5. A client with a history of myocardial infarction (MI) is being discharged with a prescription for nitroglycerin sublingual tablets. Which instruction should the nurse reinforce?

• A. Store the tablets in a cool, dry place away from light.
• B. Take a tablet every 5 minutes if chest pain occurs.
• C. Place the tablets under the tongue for sublingual absorption.
• D. Take the tablets without water for faster effect.

Correct answer: A

Rationale: The correct answer is A. Nitroglycerin tablets are light and moisture-sensitive, so they should be stored in a cool, dry place away from light to maintain their effectiveness. Option B advises taking a tablet every 5 minutes, which may lead to overdose as this frequency is too high. Option C emphasizes the correct administration route for sublingual tablets. Option D is incorrect as water is not needed for the tablets to take effect.
