Nursing Elites

1. When teaching a client with a new prescription for spironolactone, which instruction should the nurse include?

• A. Increase your intake of potassium-rich foods.
• B. Avoid consuming grapefruit juice.
• C. Take the medication with food.
• D. Monitor for signs of hyperkalemia.

Correct answer: D

Rationale: The correct answer is to instruct the client to monitor for signs of hyperkalemia when taking spironolactone since it is a potassium-sparing diuretic. Hyperkalemia is a potential adverse effect due to the medication's mechanism of action. Advising the client to increase potassium-rich foods (Choice A) would be incorrect as it can further elevate potassium levels, which could lead to hyperkalemia. Avoiding grapefruit juice (Choice B) is not directly related to spironolactone use. Though taking the medication with food (Choice C) can help reduce gastrointestinal upset, it is not the most critical instruction when initiating spironolactone therapy.

2. A client with a history of chronic heart failure is being discharged. Which instruction should the nurse include in the discharge teaching?

• A. Weigh yourself daily and report a weight gain of 2 pounds or more in a day.
• B. Restrict fluid intake to 2000 mL per day.
• C. Increase your salt intake to prevent electrolyte imbalance.
• D. Exercise vigorously at least three times a week.

Correct answer: A

Rationale: The correct answer is to weigh yourself daily and report a weight gain of 2 pounds or more in a day. This instruction is crucial because daily weights help in early detection of fluid retention, a common complication in heart failure. Monitoring weight is essential for managing heart failure and preventing exacerbations. Choice B is incorrect because fluid restriction may be necessary in some cases of heart failure, but a general limit of 2000 mL per day is not appropriate without individual assessment. Choice C is incorrect as increasing salt intake can worsen fluid retention and exacerbate heart failure symptoms. Choice D is incorrect because while exercise is beneficial for heart health, vigorous exercise may not be suitable for all heart failure patients and should be tailored to their specific condition.

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. 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.

5. Prior to a dipyridamole thallium scan, what substance should the LPN/LVN ensure the client has not consumed?

• A. Caffeine
• B. Fatty meal
• C. Excess sugar
• D. Milk products

Correct answer: A

Rationale: Caffeine should be avoided before a dipyridamole thallium scan as it can interfere with the test results. Caffeine is a stimulant that can affect the heart rate and may lead to inaccurate findings during the scan. Fatty meals, excess sugar, and milk products do not specifically interfere with the dipyridamole thallium scan procedure. Therefore, it is essential for the LPN/LVN to check and ensure that the client has not consumed caffeine prior to the procedure to obtain accurate diagnostic results.
