Nursing Elites

1. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

• A. Tall, peaked T waves
• B. ST segment depressions
• C. Shortened P-R intervals
• D. Shortening of the QRS complex

Correct answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.

2. A client with hypertension is prescribed a thiazide diuretic. What instruction should the nurse reinforce to the client?

• A. Take the medication in the morning.
• B. Increase potassium intake in the diet.
• C. Weigh yourself daily.
• D. Limit fluid intake to 2 liters per day.

Correct answer: C

Rationale: The correct answer is to weigh oneself daily. This instruction is important as daily weights help monitor fluid loss and are crucial for detecting early signs of fluid imbalance when taking a diuretic. Weighing daily allows for timely adjustments in treatment and helps prevent complications associated with fluid imbalance. Choice A is not directly related to the client's need for monitoring fluid balance. Choice B, although important for some diuretics, is not specific to thiazide diuretics. Choice D is not appropriate as limiting fluid intake without proper monitoring can lead to dehydration, especially when taking diuretics.

3. The client has angina pectoris and is prescribed nitroglycerin patches. What instruction should the nurse provide to the client?

• A. Apply the patch to the chest and leave it in place for 24 hours
• B. Apply the patch to a different site each time to prevent skin irritation
• C. Remove the patch before going to bed to prevent tolerance
• D. Cut the patch in half if experiencing headaches

Correct answer: B

Rationale: The correct instruction for the nurse to provide to the client is to apply the nitroglycerin patch to a different site each time to prevent skin irritation. Rotating the application site is crucial to prevent skin irritation and ensure consistent absorption of the medication. Applying the patch to the same site can lead to skin irritation and decreased effectiveness. Removing the patch before going to bed is not necessary, as the patch can typically be worn for a specific duration. Cutting the patch in half if experiencing headaches is not recommended and can alter the dose of the medication.

4. When teaching a client about the adverse effects of simvastatin, which of the following findings should be included as an adverse effect?

• A. Tinnitus
• B. Muscle pain
• C. Diarrhea
• D. Facial flushing

Correct answer: B

Rationale: Muscle pain should be included as an adverse effect when teaching a client about simvastatin. It can be a sign of rhabdomyolysis, a severe side effect associated with statins like simvastatin that involves muscle breakdown. Monitoring for muscle pain is crucial to prevent serious complications and ensure timely intervention. Tinnitus, diarrhea, and facial flushing are not typically associated with simvastatin use and are less common adverse effects compared to muscle pain.

5. 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.
