Animal experiments have shown that destruction of the ventromedial nuclei of the hypothalamus leads to unrestrained eating, because a specific structure is lost. Question: Which structure is lost?
- A. The amygdala
- B. The vagus nerve
- C. The satiety centre
- D. The feeding centre
Correct Answer: C
Rationale: Ventromedial zap satiety centre dies, eating runs wild, not amygdala's fear, vagus' gut, or feeding's drive. Nurses link this, a chronic overeat switch.

The nurse on a bone marrow transplant unit is caring for a patient with cancer who is preparing for HSCT. What is a priority nursing diagnosis for this patient?
- A. Fatigue related to altered metabolic processes
- B. Altered nutrition: less than body requirements related to anorexia
- C. Risk for infection related to altered immunologic response
- D. Body image disturbance related to weight loss and anorexia
Correct Answer: C
Rationale: HSCT obliterates marrow, tanking immunity risk for infection soars as neutrophils vanish, making it the top nursing diagnosis pre-transplant. Sepsis can kill fast in this window, unlike fatigue or nutrition issues, which matter but aren't immediate threats. Body image might nag later with hair loss or weight shifts, but infection's the killer to watch. Nurses lock in on this, driving strict isolation and monitoring, knowing a stray germ could derail everything in oncology's high-stakes transplant game.
Hyperglycaemia is involved in cardiovascular complications in diabetes. There are several mechanisms through which high glucose levels in endothelial cells can lead to complications. Question: Which mechanism is NOT directly associated with cardiovascular complications in diabetes?
- A. Activation of PKC
- B. AGE pathway
- C. Sorbitol pathway
- D. Fatty acid oxidation
Correct Answer: D
Rationale: High glucose trashes vessels PKC, AGEs, sorbitol clog the works, but fatty acid burn's metabolic, not direct CV. Nurses spot this, a chronic heart sidestep.
Which is not associated with atypical pneumonia?
- A. abnormal LFTs
- B. hypernatremia
- C. hypophosphatemia
- D. bilateral patchy infiltrates on CXR
Correct Answer: B
Rationale: Atypical pneumonia LFTs wobble, phosphates drop, CXR patches, agglutinins rise; sodium stays. Nurses skip this chronic salt glitch.
A nurse is performing discharge teaching for a client who was recently diagnosed with heart failure. Which of the following should be included in the client and family teaching?
- A. Low sodium diet
- B. Weekly weights
- C. Symptoms to report to the provider
- D. Fluid restriction
Correct Answer: A
Rationale: Heart failure management hinges on education to prevent exacerbations. A low sodium diet reduces fluid retention, easing cardiac workload crucial teaching for clients and families to grasp, as salt drives edema and hypertension, common pitfalls in heart failure. Weekly weights track fluid shifts daily is ideal, but weekly still aids while reporting symptoms like dyspnea flags worsening. Medication teaching ensures adherence, and fluid restriction may apply, but sodium's broader impact makes it foundational. Focusing on diet empowers lifestyle change, tackling a root cause over monitoring or restrictions alone, aligning with nursing's role in empowering self-care to stabilize this chronic condition long-term.
Which of the following is a possible treatment plan for a client diagnosed with leukemia?
- A. Dialysis
- B. Therapeutic phlebotomy
- C. Splenectomy
- D. Stem cell transplant
Correct Answer: D
Rationale: Leukemia's marrow takeover needs a reset stem cell transplant swaps diseased cells for healthy ones, a potential cure or remission shot. Dialysis aids kidneys, not blood. Phlebotomy drains polycythemia. Splenectomy's rare, symptom-based. Nurses prep for transplant, eyeing this radical fix, a game-changer in leukemia's brutal playbook.
