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. After discontinuing a peripherally inserted central line (PICC), what information is most important for the nurse to record?

• A. How the client tolerated the procedure.
• B. The length and intactness of the central line catheter.
• C. The amount of fluid left in the IV solution container.
• D. That a dressing was applied to the insertion site.

Correct answer: B

Rationale: The most important information for the nurse to record after discontinuing a peripherally inserted central line (PICC) is the length and intactness of the central line catheter. This is crucial for assessing any potential complications or safety issues post-removal. Choices A, C, and D are not as critical as ensuring the condition of the central line catheter. While noting the client's tolerance of the procedure is relevant for their care assessment, evaluating the central line's integrity takes precedence in this scenario.

3. During a screening on a patient with a recent cast on the left lower extremity, which of the following statements should the nurse be most concerned about?

• A. The patient reports, "I didn't keep my extremity elevated as the doctor asked me to."?
• B. The patient reports, "I have been having pain in my left calf."?
• C. The patient reports, "My left leg has really been itching."?
• D. The patient reports, "The arthritis in my wrists is flaring up when I put weight on my crutches."?

Correct answer: B

Rationale: The correct answer is B because pain in the left calf could indicate a potential neurovascular complication related to the casted extremity. It could suggest issues such as compartment syndrome or impaired circulation. Option A is not as concerning since not elevating the extremity may lead to swelling but is not an immediate concern. Option C indicates itching, which is common with casts and not as concerning as potential neurovascular issues. Option D, regarding arthritis in the wrists, is unrelated to the lower extremity issue being screened for.

4. The client is cared for by a nurse and calls for the nurse to come to the room, expressing feeling unwell. The client's vital signs are BP: 130/88, HR: 102, RR: 28. What should the nurse do next?

• A. Administer PRN anxiolytic
• B. Administer Antibiotics
• C. Reassure the client that everything is okay and offer food and beverage
• D. Determine the Glasgow Coma Scale

Correct answer: A

Rationale: Correct! The client's vital signs indicate tachycardia and tachypnea, which could be indicative of hypoxia. Administering a PRN anxiolytic would not address the underlying issue and could mask deterioration. Reassuring the client without further assessment or intervention could lead to a delay in appropriate care if there is a serious underlying cause for the symptoms. Determining the Glasgow Coma Scale is not relevant to the client's presenting symptoms of feeling unwell and suspecting something is wrong, coupled with abnormal vital signs.

5. Which of the following observations is most important when assessing a client's breathing?

• A. presence of breathing and pulse rate
• B. breathing pattern and adequacy of breathing
• C. presence of breathing and adequacy of breathing
• D. patient position and adequacy of breathing

Correct answer: C

Rationale: The correct answer is the presence of breathing and adequacy of breathing. It is crucial not only to confirm that the client is breathing but also to ensure that the breathing is adequate for proper oxygenation. Choices A, B, and D are incorrect because while pulse rate, breathing pattern, and patient position are relevant aspects to consider, the most critical observations in assessing a client's breathing are the presence and adequacy of breathing.
