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. Which of the following medications is a serotonin antagonist that might be used to relieve nausea and vomiting?

• A. metoclopramide (Reglan)
• B. ondansetron (Zofran)
• C. hydroxyzine (Vistaril)
• D. prochlorperazine (Compazine)

Correct answer: B

Rationale: Zofran is a serotonin antagonist commonly used to relieve nausea and vomiting by blocking serotonin receptors. Metoclopramide (Reglan) acts on dopamine receptors, hydroxyzine (Vistaril) is an antihistamine, and prochlorperazine (Compazine) is a dopamine antagonist. While these medications can also be used for nausea and vomiting, they do not primarily function as serotonin antagonists like ondansetron.

3. The client is preparing to undergo a total hysterectomy for advanced cervical cancer. The client is crying and says that she wants to have more children and is unsure if she should have the procedure. What should the nurse do?

• A. Allow the client to honestly discuss her fears and encourage her to talk more with her physician.
• B. Tell her the good things that she will be able to do without more children and encourage her to make a list of positive things.
• C. Explain to the client that her ovaries can be frozen for egg harvesting at a later time and she can find a surrogate.
• D. Advise the client to put off having the surgery until she is sure that she wants to undergo the procedure and notify the surgeon of the decision.

Correct answer: A

Rationale: In this situation, the most appropriate action for the nurse is to allow the client to express her fears and concerns openly. By encouraging her to talk more with her physician, the nurse is promoting effective communication and ensuring that the client receives adequate information to make an informed decision. Option A is correct because it acknowledges the client's emotions and empowers her to seek clarification and support from her healthcare provider. Options B and C do not address the client's emotional needs or provide a solution to her concerns regarding fertility. Option D is not appropriate as it does not prioritize the client's emotional well-being and delays necessary medical treatment for advanced cervical cancer.

4. Which instruction should be given in a health education class regarding testicular cancer?

• A. All males should perform a testicular exam after a warm bath or shower.
• B. Testicular exams should be performed on a daily basis.
• C. Reddening or darkening of the scrotum is a normal finding.
• D. Testicular exams should be performed after a warm bath or shower.

Correct answer: D

Rationale: The correct instruction for testicular cancer education is that testicular exams should be performed after a warm bath or shower as it relaxes the scrotum and makes the exam easier. Testicular exams should be done monthly by all men starting around age 15, not after the age of 30 (Choice A) or on a daily basis (Choice B), which is unnecessary and may lead to unnecessary anxiety. Reddening or darkening of the scrotum is not a normal finding (Choice C) and should be reported to a healthcare provider for further evaluation.

5. A patient 3 hours post-op from a hysterectomy is complaining of intense pain at the incision site. When assessing the patient, the nurse notes a BP of 169/93, pulse 145 bpm, and regular. What action should the nurse take?

• A. Reassure the patient that pain is normal following surgery.
• B. Administer prn Nifedipine and assess the client's response.
• C. Administer prn Meperidine HCL and assess the client's response.
• D. Recheck BP and pulse rate every 20 minutes for the next hour.

Correct answer: C

Rationale: The correct action for the nurse to take in this situation is to administer prn Meperidine HCL and assess the client's response. A BP of 169/93 and a pulse of 145 bpm indicate pain-related hypertension and sinus tachycardia, which are physiological responses to pain. Treating the cause of the increased pulse rate requires pain medication. Reassuring the patient about normal post-surgery pain is important, but addressing the physiological responses to pain is a priority. Administering Nifedipine, a calcium channel blocker, is not indicated for pain management but for hypertension. Rechecking the BP and pulse rate without addressing the pain directly does not address the underlying issue causing the elevated vital signs.
