A patient presents with acute onset of severe headache, visual disturbances, and vomiting. Imaging reveals a tumor compressing the optic chiasm. Which of the following neurological conditions is most likely responsible for these symptoms?
- A. Meningioma
- B. Glioblastoma multiforme
- C. Pituitary adenoma
- D. Medulloblastoma
Correct Answer: C
Rationale: A pituitary adenoma is a type of benign tumor that arises from the pituitary gland, which is located at the base of the brain. When a pituitary adenoma grows large enough, it can compress surrounding structures, including the optic chiasm – the point at which the optic nerves cross over in the brain. Compression of the optic chiasm can lead to symptoms such as vision problems (e.g., visual disturbances), headaches, and nausea/vomiting, which are consistent with the presentation described in the question. Meningiomas, glioblastoma multiforme, and medulloblastomas are less likely to compress the optic chiasm and present with different characteristic symptoms based on their locations and growth patterns.

Simple hysterectomy involves the removal of which structure(s)?
- A. uterus only
- B. uterus and fallopian tubes
- C. uterus and cervix
- D. uterus, ovaries, and fallopian tubes
Correct Answer: C
Rationale: A simple hysterectomy involves the removal of the uterus and cervix. It does not involve the removal of the fallopian tubes or ovaries. In some cases, the fallopian tubes may be removed along with the uterus, but this would be specified as a different type of hysterectomy (such as a total hysterectomy or a radical hysterectomy). The removal of the ovaries, if necessary, would be indicated as an oophorectomy.
A woman in active labor experiences irregular and ineffective uterine contractions, resulting in prolonged cervical dilation. What nursing intervention should be implemented to address this abnormal labor pattern?
- A. Encourage the mother to ambulate and change positions frequently.
- B. Administer intravenous opioids to enhance pain relief and relaxation.
- C. Initiate continuous electronic fetal monitoring to assess fetal well-being.
- D. Prepare for immediate cesarean section due to labor dystocia.
Correct Answer: A
Rationale: A woman experiencing irregular and ineffective uterine contractions with prolonged cervical dilation may indicate labor dystocia, also known as abnormal labor progression. To address this issue, the nursing intervention that should be implemented is to encourage the mother to ambulate and change positions frequently. This can help optimize fetal positioning and encourage descent through the birth canal by using gravity to aid in the progression of labor. Changing positions can also potentially improve the quality and effectiveness of contractions, leading to more successful cervical dilation and labor progress. Encouraging ambulation and position changes are non-invasive, patient-centered interventions that can be helpful in managing labor dystocia before considering more invasive interventions like cesarean section.
Which of the following statements accurately describes the role of dendritic cells in the immune response?
- A. Dendritic cells directly kill infected cells and tumor cells.
- B. Dendritic cells produce antibodies against pathogens.
- C. Dendritic cells activate na(cid:239)ve T cells and initiate adaptive immune responses.
- D. Dendritic cells release histamine and other inflammatory mediators.
Correct Answer: C
Rationale: Dendritic cells play a critical role in initiating adaptive immune responses by capturing antigens from pathogens, migrating to lymphoid organs, and presenting these antigens to naïve T cells. This activation of naïve T cells by dendritic cells is essential for the adaptive immune system to generate specific immune responses against pathogens. Dendritic cells act as professional antigen-presenting cells, which are specialized to capture, process, and present antigens to T cells, thereby facilitating the activation of T cells and the coordination of adaptive immune responses, such as the production of specific antibodies and the generation of memory T cells.
What post operative teaching will the patient strictly follow?
- A. Reinforce that fact that airplane travel is no longer permitted.
- B. Show patient how to gently irrigate the external auditory canal.
- C. Inform physician any dizziness that develops after she is discharged.
- D. Stress that hair washing should be avoided immediately after surgery
Correct Answer: B
Rationale: The patient who had a left total hip replacement surgery due to osteoarthritis needs to strictly follow the postoperative teaching of being shown how to gently irrigate the external auditory canal because this instruction is unrelated to a hip replacement surgery. The other options are not relevant to the surgery and patient's condition. Option A about airplane travel, Option C about dizziness, and Option D about hair washing are not appropriate instructions for a patient who had a hip replacement. It is important for healthcare providers to give accurate and relevant postoperative instructions to help the patient recover successfully.
Despite the reaction of the patient, which of the ethical principle that the nurse is responsible of providing all patients with caring attention and information?
- A. Beneficence
- B. Veracity
- C. Nonmaleficence
- D. Advocacy
Correct Answer: D
Rationale: Advocacy is the ethical principle that the nurse is responsible for providing all patients with caring attention and information, despite the reaction of the patient. Advocacy involves supporting and speaking up for the patient's best interests, ensuring they receive the care and information they need to make informed decisions about their health and well-being. Providing caring attention and information is essential in advocating for the patient's autonomy and well-being, even if the patient may not initially appreciate or react positively to these efforts.
