Nursing Elites

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. When a young client being taught to use an inhaler for asthma symptoms states the intention to use the inhaler but plans to continue smoking cigarettes, what is the best initial action by the nurse?

• A. Inform the healthcare provider of the client's statement.
• B. Explain that denial of illness can interfere with the treatment regimen.
• C. Revise the plan of care based on the client's plans to continue smoking.
• D. Review factors surrounding the client's beliefs about smoking cessation.

Correct answer: B

Rationale: The best initial action by the nurse when a client expresses plans to use an inhaler for asthma symptoms but continue smoking cigarettes is to address denial. By explaining that denial of illness can interfere with the treatment regimen, the nurse educates the client about the impact of smoking on asthma treatment. This approach helps the client understand the importance of smoking cessation in managing asthma symptoms. Informing the healthcare provider (Choice A) may be necessary but is not the initial action in this scenario. Revising the plan of care (Choice C) should be considered after addressing the client's denial and educating them. Reviewing factors surrounding the client's beliefs about smoking cessation (Choice D) is relevant but not the best initial action when denial is identified.

3. The healthcare provider is assessing a client who is receiving hemodialysis for the first time. Which of the following findings should be reported to the healthcare provider immediately?

• A. Blood pressure of 150/90 mm Hg.
• B. Nausea and vomiting.
• C. Fatigue.
• D. Headache.

Correct answer: B

Rationale: Nausea and vomiting are critical symptoms that should be reported immediately when a client is receiving hemodialysis for the first time. These symptoms could indicate a severe complication, such as hypotension, infection, electrolyte imbalance, or other adverse reactions to the procedure. It is essential to address these symptoms promptly to prevent further complications or harm to the client. Choices A, C, and D are not immediate concerns during the first hemodialysis session and can be addressed appropriately after addressing the urgent issue of nausea and vomiting.

4. A client is unsure of the decision to undergo peritoneal dialysis (PD) and wishes to discuss the advantages of this treatment with the nurse. Which statements by the nurse are accurate regarding PD? (Select all that apply.)

• A. You will not need vascular access to perform PD.
• B. There is less restriction of protein and fluids.
• C. You have flexible scheduling for the exchanges.
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, as all the statements are accurate advantages of peritoneal dialysis (PD). Peritoneal dialysis does not require vascular access, offers less restriction on protein and fluids, and provides flexibility in scheduling for the exchanges. Choice A is correct because one of the advantages of PD is not needing vascular access, which is required in hemodialysis. Choice B is correct because PD allows for less dietary restriction compared to hemodialysis. Choice C is correct because PD allows for flexible scheduling of exchanges, providing more independence to the individual undergoing treatment.

5. A nurse reviews the urinalysis of a client and notes the presence of glucose. Which action should the nurse take?

• A. Document findings and continue to monitor the client.
• B. Contact the provider and recommend a 24-hour urine test.
• C. Review the client’s recent dietary selections.
• D. Perform a capillary artery glucose assessment.

Correct answer: D

Rationale: Glucose normally is not found in the urine. The normal renal threshold for glucose is about 220 mg/dL, which means that a person whose blood glucose is less than 220 mg/dL will not have glucose in the urine. A positive finding for glucose on urinalysis indicates high blood sugar. The most appropriate action would be to perform a capillary artery glucose assessment. The client needs further evaluation for this abnormal result; therefore, documenting and continuing to monitor is not appropriate. Requesting a 24-hour urine test or reviewing the client’s dietary selections will not assist the nurse to make a clinical decision related to this abnormality.
