Which of the following is the surgical treatment of choice for end-stage heart failure?
- A. Cardiac resynchronization therapy (CRT)
- B. Percutaneous angiogram
- C. Genetic counseling
- D. Ventricular assist devices (VADs)
Correct Answer: D
Rationale: End-stage heart failure, when drugs and pacing fail, leans on ventricular assist devices mechanical pumps aiding circulation, a bridge to transplant or destination therapy. CRT syncs ventricles, less invasive, but VADs tackle severe pump collapse. Angiograms diagnose, not treat; genetic counseling's irrelevant. Nurses prep for VADs, managing post-op risks, the go-to surgical fix in this terminal cardiac scenario.

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 nurse has taught a client about dietary changes that can reduce the chances of developing cancer. What statement by the client indicates the nurse needs to provide additional teaching?
- A. Foods high in vitamin A and vitamin C are important.
- B. I'll have to cut down on the amount of bacon I eat.
- C. I'm so glad I don't have to give up my juicy steaks.
- D. Vegetables, fruit, and high-fiber grains are important.
Correct Answer: C
Rationale: Diet plays a significant role in cancer prevention, and nurses often educate clients on evidence-based dietary adjustments. Foods rich in vitamins A and C, such as carrots and citrus fruits, are known to have antioxidant properties that may reduce cancer risk by neutralizing free radicals. Reducing processed meats like bacon is advised due to their association with colorectal cancer, linked to nitrates and high fat content. Similarly, high vegetable, fruit, and fiber intake is recommended for their protective effects against various cancers, including colon cancer. However, excessive red meat consumption, such as steaks, is a known risk factor for cancers like colorectal and prostate cancer due to saturated fats and carcinogenic compounds formed during cooking. The client's statement about not giving up steaks suggests a misunderstanding, indicating the nurse must clarify that limiting red meat, not just processed meat, is part of a cancer-preventive diet. This additional teaching is essential to ensure the client adopts a comprehensive approach to reducing cancer risk.
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.
Which does not require post exposure prophylaxis for rabies?
- A. scratch
- B. bite on face
- C. bite on extremity
- D. skin contact with blood, urine or faeces
Correct Answer: D
Rationale: Rabies PEP bites, scratches, bat splashes trigger; blood, pee, poop on skin don't. Nurses skip this chronic non-risk.
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.
