Nursing Elites

1. The client with chronic renal failure is on a fluid restriction. Which of the following statements by the client indicates that the teaching has been effective?

• A. I will limit my fluid intake to prevent fluid overload.
• B. I can drink as much fluid as I want as long as I take my medication.
• C. I will skip dialysis sessions if I feel tired.
• D. I will limit my fluid intake to 1 liter per day.

Correct answer: A

Rationale: Choice A is the correct answer because it demonstrates the client's understanding of the need to limit fluid intake to prevent fluid overload, which is crucial in managing chronic renal failure. Adequate fluid restriction is essential to prevent complications such as fluid overload and electrolyte imbalances. Choice B is incorrect as it promotes excessive fluid intake, which can worsen the client's condition by putting additional stress on the kidneys. Choice C is incorrect as skipping dialysis sessions can lead to a buildup of toxins in the body, worsening renal failure and potentially leading to life-threatening complications. Choice D is incorrect because limiting fluid intake to a specific volume may not be appropriate for all clients and can vary depending on individual needs, medical condition, and healthcare provider recommendations.

2. A client with a completed ischemic stroke has a blood pressure of 180/90 mm Hg. Which action should the nurse implement?

• A. Position the head of the bed (HOB) flat.
• B. Withhold intravenous fluids.
• C. Administer a bolus of IV fluids.
• D. Give an antihypertensive medication.

Correct answer: D

Rationale: In a client with a completed ischemic stroke, an elevated blood pressure like 180/90 mm Hg requires immediate intervention to prevent further damage. Giving an antihypertensive medication is essential to reduce the risk of recurrent stroke or complications related to hypertension. Positioning the head of the bed flat, withholding IV fluids, or administering a bolus of IV fluids are not appropriate actions for managing elevated blood pressure in this scenario and may not address the underlying cause of the hypertension or prevent potential complications.

3. The client has been managing angina episodes with nitroglycerin. Which of the following indicates the drug is effective?

• A. Decreased chest pain.
• B. Increased blood pressure.
• C. Decreased blood pressure.
• D. Decreased heart rate.

Correct answer: A

Rationale: The correct answer is A: Decreased chest pain. Nitroglycerin is a vasodilator that works by decreasing myocardial oxygen consumption, which helps to reduce chest pain caused by angina. Therefore, a reduction in chest pain is a positive indicator of the drug's effectiveness. Choices B, C, and D are incorrect because nitroglycerin does not typically increase blood pressure or heart rate; instead, it often causes a decrease in blood pressure due to vasodilation and may cause a reflex tachycardia (increased heart rate) as a compensatory response to lowered blood pressure.

4. The nurse is teaching a nursing student about the minimal effective concentration (MEC) of antibiotics. Which statement by the nursing student indicates understanding of this concept?

• A. A serum drug level greater than the MEC ensures that the drug is bacteriostatic.
• B. A serum drug level greater than the MEC broadens the spectrum of the drug.
• C. A serum drug level greater than the MEC helps eradicate bacterial infections.
• D. A serum drug level greater than the MEC increases the therapeutic index.

Correct answer: C

Rationale: The MEC is the minimum amount of drug needed to halt the growth of a microorganism. A level greater than the MEC helps eradicate infections. Drugs at or above the MEC are usually bactericidal, not bacteriostatic. Therefore, choice A is incorrect. Broadening the spectrum of a drug refers to its range of activity against different microorganisms, which is not directly related to MEC. Thus, choice B is incorrect. Increasing the therapeutic index involves maximizing the effectiveness of a drug while minimizing its toxicity, which is not specifically related to MEC. Therefore, choice D is also incorrect.

5. A client in the emergency department is severely dehydrated and is prescribed 3 L of intravenous fluid over 6 hours. At what rate (mL/hr) should the nurse set the intravenous pump to infuse the fluids? (Record your answer using a whole number.)

• A. 500 mL/hr
• B. 400 mL/hr
• C. 550 mL/hr
• D. 600 mL/hr

Correct answer: A

Rationale: To calculate the rate of the intravenous pump, divide the total volume of fluid (3 L = 3000 mL) by the total time in hours (6 hours), which equals 500 mL/hr. The correct answer is A. Choice B (400 mL/hr) is incorrect as it would result in a slower infusion rate. Choice C (550 mL/hr) and Choice D (600 mL/hr) are incorrect as they would result in a faster infusion rate, exceeding the prescribed amount of fluid to be infused over 6 hours.
