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 has a new prescription for propranolol. Which of the following instructions should be included?

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

Correct answer: B

Rationale: The correct answer is to monitor heart rate daily. Propranolol is a beta-blocker that can lower heart rate and blood pressure, so it is essential to monitor heart rate regularly to detect any signs of bradycardia, a potential side effect of the medication. Choice A is incorrect because propranolol can be taken with or without food. Choice C is incorrect as increasing potassium-rich foods is not specifically required with propranolol. Choice D is also incorrect as there is no need to avoid consuming dairy products with propranolol.

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 with a history of angina pectoris reports chest pain after climbing stairs. What should be the nurse's first action?

• A. Administer oxygen.
• B. Administer nitroglycerin.
• C. Sit the client down and rest.
• D. Check the client's blood pressure.

Correct answer: C

Rationale: The correct action for a client experiencing anginal pain, like chest pain after climbing stairs, is to sit the client down and have them rest. Resting reduces myocardial oxygen demand, which can help relieve anginal pain. Administering oxygen or nitroglycerin may be appropriate interventions after the client has been seated and rested. Checking the client's blood pressure is important but not the immediate priority when a client is experiencing anginal pain. Therefore, the first action should be to sit the client down and allow them to rest.

5. A client with coronary artery disease is prescribed a low-cholesterol diet. The nurse should reinforce which dietary selection made by the client?

• A. Eggs and bacon
• B. Oatmeal with fresh fruit
• C. Cream of chicken soup
• D. Grilled cheese sandwich

Correct answer: B

Rationale: Oatmeal with fresh fruit is a suitable choice for a client with coronary artery disease prescribed a low-cholesterol diet. This option is high in fiber and nutrients, making it a heart-healthy selection. Oatmeal and fresh fruits are low in cholesterol and saturated fats, which helps in managing coronary artery disease. Choices A, C, and D are higher in cholesterol and saturated fats, which can be detrimental for individuals with this condition.
