HESI Medical Surgical Practice Quiz
1. 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.
2. What is the nurse manager’s role in improving the quality of care on the unit?
- A. The nurse manager is responsible for setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals.
- B. The nurse manager is responsible for monitoring patient outcomes and implementing changes to improve the quality of care on the unit.
- C. The nurse manager is responsible for ensuring that staff members follow established procedures and protocols to maintain the quality of care on the unit.
- D. The nurse manager is responsible for providing feedback and coaching to staff members to help them improve their performance and achieve the unit’s quality goals.
Correct answer: A
Rationale: The nurse manager plays a crucial role in improving the quality of care on the unit by setting goals and priorities for the unit and ensuring that staff members are working towards achieving those goals. This involves strategic planning, coordination, and leadership to guide the team in delivering high-quality patient care. Option B is incorrect as while monitoring patient outcomes is important, it is not the primary role of the nurse manager in improving care quality. Option C is incorrect because while ensuring staff adherence to procedures is important, it is a part of maintaining quality rather than actively improving it. Option D is incorrect as providing feedback and coaching, though essential, is not the primary role of the nurse manager in setting goals and priorities for quality improvement.
3. While assessing a client who is admitted with heart failure and pulmonary edema, the nurse identifies dependent peripheral edema, an irregular heart rate, and a persistent cough that produces pink blood-tinged sputum. After initiating continuous telemetry and positioning the client, which intervention should the nurse implement?
- A. Administer prescribed diuretics
- B. Prepare for intubation
- C. Notify the healthcare provider immediately
- D. Obtain sputum sample
Correct answer: D
Rationale: The client's cough producing pink, frothy sputum is indicative of pulmonary edema, which needs immediate treatment. Obtaining a sputum sample helps identify any infection that may be contributing to the pulmonary issues. Administering diuretics is essential in managing pulmonary edema but obtaining a sputum sample should take priority. Intubation may be necessary in severe cases but is not the initial intervention. Notifying the healthcare provider is important, but immediate action to diagnose and treat the condition is crucial.
4. Before a client with renal failure undergoes hemodialysis, what should the nurse assess?
- A. Check the client's potassium levels
- B. Review the client's medication list
- C. Assess the client's peripheral pulses
- D. Monitor the client's urine output
Correct answer: A
Rationale: The correct answer is to check the client's potassium levels. Potassium levels are crucial to assess before hemodialysis in a client with renal failure because hyperkalemia (high potassium) is a common complication in these patients. Hemodialysis aims to remove excess potassium from the blood, making it essential to monitor potassium levels to determine the need for appropriate interventions. Reviewing the client's medication list (Choice B) is important for overall care but is not as directly relevant to the immediate concerns before hemodialysis. Assessing peripheral pulses (Choice C) and monitoring urine output (Choice D) are important aspects of nursing assessment but are not as directly related to the specific preparation needed before hemodialysis in a client with renal failure.
5. Which of the following is a common complication of hypertension?
- A. Diabetes.
- B. Heart failure.
- C. Kidney failure.
- D. Stroke.
Correct answer: D
Rationale: The correct answer is D: Stroke. Hypertension can lead to stroke due to the increased pressure on blood vessels in the brain, which can result in reduced blood flow and oxygen to the brain tissue. While choices B (Heart failure) and C (Kidney failure) can be complications of hypertension, they are not as directly associated as stroke. Choice A, Diabetes, is not a direct complication of hypertension but rather a separate condition that can be influenced by various factors. However, stroke is more commonly linked to the increased pressure on blood vessels in the brain in individuals with hypertension.
