Nursing Elites

1. An infection in a central venous access device is not eliminated by giving antibiotics through the catheter. How might bacterial glycocalyx contribute to this?

• A. It protects the bacteria from antibiotic and immunologic destruction.
• B. Glycocalyx neutralizes the antibiotic, rendering it ineffective.
• C. It competes with the antibiotic for binding sites on the microbe.
• D. Glycocalyx provides nutrients for microbial growth.

Correct answer: A

Rationale: Bacterial glycocalyx is a viscous polysaccharide or polypeptide slime that covers microbes. It plays a significant role in protecting bacteria by enhancing adherence to surfaces, resisting phagocytic engulfment by white blood cells, and preventing antibiotics from contacting the microbe. Choice A is correct because glycocalyx shields the bacteria from both antibiotics and the immune system, allowing the infection to persist. Choices B, C, and D are incorrect because glycocalyx does not neutralize antibiotics, compete for binding sites with antibiotics, or provide nutrients for microbial growth.

2. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?

• A. Participate in at least 30 minutes of moderate physical activity 3 to 5 days per week.
• B. Engage in an aerobic exercise class every day.
• C. Limit your alcohol intake to a moderate level.
• D. The best way to lose weight is to follow a balanced diet.

Correct answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.

3. A patient has been diagnosed with diabetes mellitus. Which of the following is not a clinical sign of diabetes mellitus?

• A. Polyphagia
• B. Polyuria
• C. Metabolic acidosis
• D. Lower extremity edema

Correct answer: D

Rationale: Polyphagia, polyuria, and metabolic acidosis are common clinical signs of diabetes mellitus. Polyphagia refers to excessive hunger, polyuria is excessive urination, and metabolic acidosis can occur due to poorly controlled diabetes. Lower extremity edema, on the other hand, is not a typical clinical sign of diabetes mellitus. Edema in the lower extremities is more commonly associated with conditions like heart failure or kidney disease rather than diabetes mellitus.

4. What is the best position for a client immediately following a bilateral salpingooophorectomy?

• A. Fowler's
• B. Modified Sims
• C. Side lying
• D. Flat supine

Correct answer: C

Rationale: The best position for a client immediately following a bilateral salpingooophorectomy is side lying. This position promotes comfort with the knees flexed and ensures proper airway management. Fowler's position (Choice A) would not be ideal as it involves sitting at a 90-degree angle, potentially causing discomfort after this procedure. Modified Sims position (Choice B) is typically used for rectal examinations, not for post-surgical management. Flat supine (Choice D) may not be the best choice immediately after surgery as it does not provide the same level of comfort and airway protection as side lying with knees flexed.

5. A healthcare provider is screening patients for various vaccines. Which of the following vaccines is contraindicated during pregnancy?

• A. Diphtheria
• B. Hepatitis B
• C. Mumps
• D. Tetanus

Correct answer: C

Rationale: The correct answer is Mumps. The Mumps vaccine, along with the Rubella vaccine, is contraindicated during pregnancy due to the theoretical risk of affecting the developing fetus. Diphtheria, Hepatitis B, and Tetanus vaccines are considered safe during pregnancy and are often recommended to protect both the pregnant individual and the developing fetus. Therefore, choices A, B, and D are incorrect.
