A pregnant woman presents with painless, bright red vaginal bleeding at 34 weeks gestation. On examination, the cervix is found to be closed. Which of the following conditions is the most likely cause of these symptoms?
- A. Ectopic pregnancy
- B. Abruptio placentae
- C. Placenta previa
- D. Gestational trophoblastic disease
Correct Answer: C
Rationale: Placenta previa is a condition where the placenta partially or completely covers the cervix, leading to painless vaginal bleeding during pregnancy. In the scenario described, the painless, bright red vaginal bleeding at 34 weeks gestation with a closed cervix is classic for placenta previa. This condition is more common in the third trimester and can be diagnosed through ultrasound. It is important to manage placenta previa carefully to prevent complications such as severe bleeding, preterm birth, and maternal/fetal distress.

During surgery, the nurse observes an unusual odor emanating from the surgical site. What should the nurse do?
- A. Document the observation in the patient's chart
- B. Ignore the odor and continue with the procedure
- C. Inform the surgeon immediately and assess for signs of infection
- D. Request additional suctioning to remove the odor
Correct Answer: C
Rationale: If the nurse observes an unusual odor emanating from the surgical site during surgery, it is important to inform the surgeon immediately and assess for signs of infection. Changes in odor can sometimes be an early sign of infection, which requires prompt attention and intervention. By communicating with the surgeon and conducting a thorough assessment, the nurse can help ensure the timely detection and management of any potential complications, such as infection, that may be affecting the patient's surgical outcome. Prompt action in response to unusual observations is crucial to maintaining patient safety and well-being during surgical procedures.
The nurse is aware that a major difference between Hodgkin's lymphoma and non- Hodgkin's lymphoma is that:_________________
- A. Hodgkin's lymphoma occurs only in young adults
- B. Hodgkin's lymphoma is considered potentially curable
- C. Non-Hodgkin's lymphoma can manifest in multiple organs
- D. Non-Hodgkin's lymphoma is treated only with radiation therapy
Correct Answer: B
Rationale: One of the major differences between Hodgkin's lymphoma and non-Hodgkin's lymphoma is that Hodgkin's lymphoma is considered potentially curable, while non-Hodgkin's lymphoma is typically not curable. Hodgkin's lymphoma is characterized by the presence of Reed-Sternberg cells, which are not found in non-Hodgkin's lymphoma. Additionally, Hodgkin's lymphoma tends to spread in a more orderly and predictable manner through the lymph nodes, making it easier to treat and potentially cure with the appropriate combination of chemotherapy, radiation therapy, and stem cell transplant. On the other hand, non-Hodgkin's lymphoma is a diverse group of lymphomas that can vary greatly in presentation, behavior, and response to treatment, with some subtypes being more aggressive and resistant to treatment. Therefore, the potential for cure is higher in Hodgkin's lymphoma compared to non-Hodgkin's lymph
The nurse is aware that the proper management of poisoning includes the following EXCEPT to
- A. perform hemoperfusion
- B. remove the toxin through dialysis
- C. dilute the ingested substance
- D. induce vomiting after ingestion of the caustic substance or petroleum distillate
Correct Answer: A
Rationale: Hemoperfusion is not a standard management technique for poisoning. The other options are commonly used methods in managing poisoning cases.
Which IMPORTANT Information the nurse should inform the public about rabies?
- A. It could be prevented
- B. It is an ordinary disease
- C. Rabies is not deadly
- D. It kills
Correct Answer: A
Rationale: The nurse should inform the public that rabies can be prevented. This is an extremely important piece of information to help raise awareness about the disease and promote preventive measures such as timely vaccination of both animals and humans. Rabies is a deadly viral infection that affects the central nervous system, and prevention through vaccination is highly effective in controlling its spread. By emphasizing the preventability of rabies, the nurse can educate the public on the importance of taking proactive steps to avoid contracting the disease.
A patient undergoing mechanical ventilation in the ICU develops ventilator-associated pneumonia (VAP) caused by multidrug-resistant organisms (MDROs). What intervention should the healthcare team prioritize to manage the patient's infection?
- A. Administer combination antibiotic therapy targeting MDROs.
- B. Perform bronchoalveolar lavage for diagnostic purposes.
- C. Implement strict isolation precautions to prevent transmission.
- D. Recommend prophylactic antifungal therapy to prevent candidiasis.
Correct Answer: A
Rationale: The most appropriate intervention for managing ventilator-associated pneumonia (VAP) caused by multidrug-resistant organisms (MDROs) is to administer combination antibiotic therapy targeting the specific resistant pathogens identified in the patient's culture results. MDROs are often resistant to multiple antibiotics, so combination therapy is required to maximize the chances of effectively treating the infection. Identifying the specific pathogens causing the VAP through cultures is crucial in tailoring the antibiotic therapy to target these organisms effectively. Implementing appropriate antibiotic therapy promptly is essential to improve outcomes and prevent further complications in patients with VAP caused by MDROs. Option A is the priority intervention in this case to address the multidrug-resistant nature of the infection and provide targeted treatment for the patient.
