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. A client who has undergone abdominal surgery calls the nurse and reports that she just felt 'something give way' in the abdominal incision. The nurse checks the incision and notes the presence of wound dehiscence. The nurse immediately:

• A. Contacts the physician
• B. Documents the findings
• C. Places the client in a supine position with the legs flat
• D. Covers the abdominal wound with a sterile dressing moistened with sterile saline solution

Correct answer: D

Rationale: In the scenario described, the presence of wound dehiscence indicates a separation of the layers of the surgical incision. The immediate priority for the nurse is to cover the abdominal wound with a sterile dressing moistened with sterile saline solution. This helps to protect the wound from contamination and promotes a moist environment conducive to healing. Contacting the physician (Choice A) is important, but the initial action should be to address the wound. Documenting the findings (Choice B) is necessary but not the immediate priority. Placing the client in a supine position with the legs flat (Choice C) is not indicated in this situation as wound dehiscence requires wound care intervention.

3. The healthcare provider is assessing a client undergoing peritoneal dialysis. Which of the following findings should be reported immediately to the physician?

• A. Clear dialysate outflow.
• B. Clear dialysate inflow.
• C. Cloudy dialysate outflow.
• D. Increased blood pressure.

Correct answer: C

Rationale: Cloudy dialysate outflow should be reported immediately to the physician as it is a concerning sign of peritonitis, a severe infection of the peritoneum. Peritonitis is a serious complication of peritoneal dialysis that requires prompt medical intervention to prevent further complications. Clear dialysate outflow and inflow are normal findings in peritoneal dialysis and do not indicate an immediate need for intervention. Increased blood pressure, while important to monitor, is not directly related to peritoneal dialysis and would not be the priority over the potentially life-threatening complication of peritonitis.

4. A client with autosomal dominant polycystic kidney disease (ADPKD) asks, “Will my children develop this disease?” How should the nurse respond?

• A. No genetic link is known, so your children are not at increased risk.
• B. Your sons will develop this disease because it has a sex-linked gene.
• C. Only if both you and your spouse are carriers of this disease.
• D. Each of your children has a 50% risk of having ADPKD.

Correct answer: D

Rationale: Children whose parent has the autosomal dominant form of PKD have a 50% chance of inheriting the gene that causes the disease. ADPKD is transmitted as an autosomal dominant trait and therefore is not gender-specific. Both parents do not need to have this disorder. Choice A is incorrect because ADPKD has a known genetic link and a definitive mode of inheritance. Choice B is incorrect as ADPKD is not sex-linked but autosomal dominant. Choice C is incorrect because ADPKD follows an autosomal dominant inheritance pattern and does not require both parents to be carriers for the child to inherit the disease.

5. The client with chronic renal failure is receiving instruction on dietary restrictions. Which of the following food items should the client be instructed to avoid?

• A. Bananas.
• B. Apples.
• C. Rice.
• D. Potatoes.

Correct answer: A

Rationale: The correct answer is A: Bananas. Bananas are high in potassium, and individuals with chronic renal failure are often advised to limit potassium intake to prevent hyperkalemia. Apples, rice, and potatoes are lower in potassium and can be included in moderation in the diet of clients with chronic renal failure.
