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.

People with obesity generally respond more strongly to food cues than non-obese people. Question: Which behavioural training is most indicated to reduce this mechanism?

  • A. Cognitive modulation training
  • B. Compulsivity training
  • C. Extinction training
  • D. None of the options above
Correct Answer: C

Rationale: Food cues overdrive extinction dims them, not cognitive tweaks or compulsion drills. Nurses train this, a chronic cue fade.

The nurse obtains information about a hospitalized patient who is receiving chemotherapy for colorectal cancer. Which information about the patient alerts the nurse to discuss a possible change in cancer therapy with the health care provider?

  • A. Frequent loose stools
  • B. Nausea and vomiting
  • C. Elevated white blood count (WBC)
  • D. Increased carcinoembryonic antigen (CEA)
Correct Answer: D

Rationale: Rising CEA screams colorectal cancer's dodging chemo tumor marker jumps mean progression, trumping GI woes (A, B) or high WBC (C maybe infection). Nurses in oncology push this CEA's a red flag, signaling therapy's failing, needing a switch.

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.

For a patient with osteogenic sarcoma, you would be particularly vigilant for elevations in which laboratory value?

  • A. Sodium
  • B. Calcium
  • C. Potassium
  • D. Hematocrit
Correct Answer: B

Rationale: Osteogenic sarcoma, a bone cancer, often triggers hypercalcemia bone destruction releases calcium into blood, risking arrhythmias or kidney damage, a life-threatening shift demanding close watch. Sodium and potassium imbalances aren't bone-specific, more tied to general metabolism or treatment side effects. Hematocrit reflects anemia, common in cancer but not osteogenic sarcoma's hallmark. Calcium's spike, linked to osteolysis, makes it the nurse's focus elevations signal tumor activity or progression, prompting urgent interventions like fluids or bisphosphonates, a vigilance rooted in this cancer's skeletal impact and metabolic havoc.

The home health nurse is performing a home visit for an oncology patient discharged 3 days ago after completing treatment for non-Hodgkin lymphoma. The nurse's assessment should include examination for the signs and symptoms of what complication?

  • A. Tumor lysis syndrome (TLS)
  • B. Syndrome of inappropriate antidiuretic hormone (SIADH)
  • C. Disseminated intravascular coagulation (DIC)
  • D. Hypercalcemia
Correct Answer: A

Rationale: Non-Hodgkin lymphoma's fast cell turnover, plus recent chemo, primes for TLS dead cells dump potassium, phosphorus, and uric acid, risking kidney failure days post-treatment. SIADH (low sodium) and hypercalcemia (bone mets) are less tied to this timeline. DIC's bleeding chaos isn't lymphoma's usual post-chemo hit. Nurses hunt TLS signs fatigue, nausea, arrhythmias knowing it's a fatal oncology curveball if missed early.
