A government initiative to reduce the effects of fatigue in the workforce has recently been rolled out. As anaesthetic lead, you are asked by the chief executive of your institution to develop strategies to reduce fatigue in your department. Appropriate strategies are likely to include:

  • A. Changing the frequency of night shifts on the on-call rota from every 3 days to every 2 weeks.
  • B. Including a section in the trainee's handbook on the signs of fatigue, along with prevention and management strategies.
  • C. Acquiring a departmental exercise bike.
  • D. Reducing the number of night shifts worked by colleagues over 55 years of age.
Correct Answer: A

Rationale: Fatigue mitigation in anaesthesia enhances safety. Reducing night shift frequency from every 3 days to every 2 weeks allows recovery (per sleep science, 48-72 hours post-night shift), significantly cutting cumulative fatigue versus less impactful measures. A handbook educates on fatigue signs (e.g., yawning, errors) and strategies (naps, caffeine), but it's passive. An exercise bike offers minor alertness boosts but not sustained relief. Age-based shift reduction addresses older workers' recovery needs, yet evidence favors roster spacing for all. Refreshments help minimally. Frequent night shifts disrupt circadian rhythms and sleep homeostasis, amplifying error risk (e.g., medication misdosing); a 2-week gap aligns with occupational health guidelines for sustained performance.

Regarding PID

  • A. Trichomonas and Gardnerella are commonest organisms
  • B. Associated with irregular menstruation
  • C. Absence of fever and cervical excitation excludes diagnosis
Correct Answer: B

Rationale: PID chlamydia, gonorrhea lead, irregular menses tie, fever and motion can hide. Nurses link this chronic pelvic thread.

The home health nurse is caring for a patient who has been receiving interferon therapy for treatment of cancer. Which statement by the patient indicates a need for further assessment?

  • A. I have frequent muscle aches and pains.'
  • B. I rarely have the energy to get out of bed.'
  • C. I experience chills after I inject the interferon.'
  • D. I take acetaminophen (Tylenol) every 4 hours.'
Correct Answer: B

Rationale: Interferon's flu-like hell aches , chills , and Tylenol use are par but crushing fatigue flags dose-limiting toxicity, hinting at overdose or depression. Nurses in oncology dig deeper here rarely out of bed' could mean more than side effects, needing med tweaks or psych consult, critical for home care balance.

Cortical stimulation:

  • A. Occurs before resection of a tumour.
  • B. Localizes areas involved with hearing.
  • C. Occurs by indirect application of electrodes.
  • D. Allows identification of Wernicke's area, which is involved in the comprehension of language.
Correct Answer: D

Rationale: Cortical stimulation in awake craniotomy maps eloquent brain areas before tumor resection to avoid functional loss. It's performed pre-resection to define safe boundaries, localizing motor, sensory, and language areas, including hearing-related regions in the temporal lobe. Electrodes are applied directly to the cortex, not indirectly, for precision. Wernicke's area, in the dominant temporal lobe, is critical for language comprehension, and stimulation identifies it by eliciting speech errors (e.g., paraphasia). Seizures can occur, managed with cold saline irrigation, not warm. The ability to pinpoint Wernicke's area is pivotal, as its preservation ensures postoperative language function, balancing oncologic goals with quality of life in eloquent cortex surgeries.

A previously well 25 week pregnant lady presents as a neighbours child she was looking after 2 days ago has developed chicken pox. What would you advise?

  • A. Check her serology
  • B. Zoster immunoglobulin if negative serology
  • C. Prophylactic aciclovir if negative serology
  • D. A and B
Correct Answer: A

Rationale: Pregnant, 25 weeks check serology; VZIG or aciclovir jumps if negative, not all. Nurses test first, a chronic fetal guard.

The nurse is assessing a 14-year-old girl with a tumor. Which of the following findings would indicate Ewing sarcoma?

  • A. Child complains of dull bone pain just above the knee.
  • B. Palpation reveals non-tender swelling on the right ribs.
  • C. Parents report a mass on the abdomen that crosses the midline.
  • D. Palpation reveals asymptomatic mass on the upper back.
Correct Answer: B

Rationale: Ewing sarcoma is a rare bone cancer primarily affecting children and adolescents, typically arising in flat bones like the pelvis, chest wall (e.g., ribs), or vertebrae, and the diaphysis of long bones. A hallmark is a palpable, non-tender mass, making non-tender swelling on the ribs a strong indicator, as it aligns with the tumor's common chest wall location and lack of initial pain sensitivity. Dull bone pain above the knee suggests a long bone issue, possibly osteosarcoma, which favors the metaphysis, not Ewing's typical diaphysis site. An abdominal mass crossing the midline is more characteristic of Wilms tumor or neuroblastoma, not Ewing sarcoma. An asymptomatic upper back mass could suggest various tumors, but lacks specificity for Ewing's flat bone preference. Nurses must recognize this presentation to facilitate prompt imaging and biopsy, critical for early diagnosis and treatment planning in pediatric oncology.
