Nursing Elites

1. A client has a new prescription for transdermal nitroglycerin patches. Which of the following instructions should be included for proper use?

• A. Apply the patch to the same site each day.
• B. Place the patch on an area of skin away from skin folds and joints.
• C. Keep the patch on 24 hours per day.
• D. Replace the patch every 72 hours.

Correct answer: B

Rationale: Placing the nitroglycerin patch on an area of skin away from skin folds and joints is crucial to ensure optimal absorption and effectiveness of the medication. Placing the patch on skin folds or joints can interfere with absorption, potentially reducing the patch's efficacy. Therefore, it is essential to follow this instruction to maximize the therapeutic benefits of the nitroglycerin patches. The other options are incorrect because applying the patch to the same site each day can lead to skin irritation, keeping the patch on 24 hours per day may not be necessary depending on the specific patch instructions, and replacing the patch every 72 hours is not the standard frequency for nitroglycerin patches.

2. The client with Raynaud's phenomenon is being taught by the nurse about preventing episodes. Which instruction should the nurse reinforce?

• A. Wear gloves in cold weather.
• B. Avoid caffeine and chocolate.
• C. Increase intake of vitamin C.
• D. Use a heating pad for warmth.

Correct answer: A

Rationale: The correct answer is A: 'Wear gloves in cold weather.' Wearing gloves in cold weather is essential for preventing vasoconstriction and subsequent episodes of Raynaud's phenomenon. Cold temperatures can trigger vasospasms in individuals with Raynaud's, and wearing gloves helps maintain warmth and prevent the constriction of blood vessels in the extremities, reducing the likelihood of an episode. Choices B, C, and D are incorrect because while avoiding caffeine and chocolate, increasing vitamin C intake, and using a heating pad for warmth can be beneficial for overall health, they are not specifically targeted at preventing Raynaud's phenomenon episodes triggered by cold weather.

3. A client has a new prescription for methotrexate. Which of the following instructions should the nurse include?

• A. Avoid consuming dairy products.
• B. Take the medication on an empty stomach.
• C. Increase your intake of folic acid.
• D. Monitor for signs of hyperglycemia.

Correct answer: C

Rationale: Increasing folic acid intake is crucial when taking methotrexate because the medication can lead to folic acid deficiency. Folic acid supplementation helps counteract this deficiency and reduces the risk of adverse effects associated with methotrexate therapy. Choices A, B, and D are incorrect. Avoiding dairy products is not specifically necessary for methotrexate therapy. Methotrexate is usually taken with food to reduce gastrointestinal side effects, so taking it on an empty stomach is not recommended. Monitoring for signs of hyperglycemia is not directly related to methotrexate use.

4. A client with a history of hypertension is being discharged on a low-sodium diet. Which statement by the client indicates a need for further teaching?

• A. I will use fresh herbs and spices instead of salt.
• B. I will avoid canned soups and processed foods.
• C. I can eat as much bacon and sausage as I want because they taste good.
• D. I will read food labels to check for sodium content.

Correct answer: C

Rationale: Choice C is the correct answer because bacon and sausage are high in sodium, which contradicts the low-sodium diet requirement. Consuming them freely would contribute to increased sodium intake, which is not suitable for managing hypertension. Choices A, B, and D demonstrate appropriate understanding and actions for a low-sodium diet, such as using alternatives to salt, avoiding processed foods, and checking food labels for sodium content.

5. 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.
