Nursing Elites

1. A nurse is caring for a client who is at risk for developing pressure ulcers. Which of the following interventions should the nurse implement?

• A. Use a donut-shaped cushion for sitting
• B. Turn the client every 4 hours
• C. Elevate the head of the bed to 45 degrees
• D. Massage reddened areas to increase circulation

Correct answer: C

Rationale: Elevating the head of the bed reduces pressure on bony prominences, which helps prevent pressure ulcers.

2. A client with a new diagnosis of hypertension is receiving teaching from a nurse. Which of the following statements by the client indicates an understanding of the teaching?

• A. I will check my blood pressure at least once a week.
• B. I will avoid eating foods high in potassium.
• C. I should exercise for 30 minutes at least 5 days a week.
• D. I will take my medication only when I feel dizzy.

Correct answer: C

Rationale: The correct answer is C. Regular exercise is an essential component in managing hypertension. Exercising for at least 30 minutes a day, at least 5 days a week, can help control blood pressure. Checking blood pressure regularly (choice A) is important, but not as indicative of understanding the teaching as the commitment to regular exercise. Avoiding foods high in potassium (choice B) is not a typical recommendation for managing hypertension. Taking medication only when feeling dizzy (choice D) is incorrect and potentially dangerous; medications should be taken as prescribed by the healthcare provider.

3. A nurse is preparing to administer dopamine hydrochloride at 4 mcg/kg/min for a client weighing 80 kg. How many mL/hr should the nurse set the IV infusion to deliver?

• A. 6 mL/hr
• B. 8 mL/hr
• C. 12 mL/hr
• D. 16 mL/hr

Correct answer: A

Rationale: To calculate the correct rate, you first need to convert the weight to micrograms: 4 mcg/kg/min * 80 kg = 320 mcg/min. Then, convert micrograms to milligrams: 320 mcg/min / 1000 = 0.32 mg/min. Next, calculate how many milligrams per hour: 0.32 mg/min * 60 min/hr = 19.2 mg/hr. Finally, determine the mL/hr rate by using the concentration provided: 19.2 mg/hr / 800 mg in 250 mL = 6 mL/hr. Therefore, the correct answer is 6 mL/hr. Choice B, 8 mL/hr, is incorrect as it does not reflect the accurate calculation based on the weight and drug concentration. Choices C and D, 12 mL/hr and 16 mL/hr, are also incorrect as they do not align with the correct calculation of the infusion rate for dopamine hydrochloride based on the client's weight and the medication concentration.

4. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

5. A nurse is caring for a client who has heart failure and a prescription for furosemide. Which of the following findings should the nurse identify as an indication that the medication is effective?

• A. Increased shortness of breath.
• B. Decreased peripheral edema.
• C. Increased jugular venous distention.
• D. Increased heart rate.

Correct answer: B

Rationale: The correct answer is B: Decreased peripheral edema. Furosemide is a diuretic that helps in reducing fluid overload in clients with heart failure by increasing urine output. A decrease in peripheral edema indicates that the medication is effectively removing excess fluid from the body. Choices A, C, and D are incorrect because they do not indicate an improvement in the client's condition. Increased shortness of breath, increased jugular venous distention, and increased heart rate are all signs of worsening heart failure and would not be expected findings when furosemide is effective.
