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.

A client diagnosed with stable angina is complaining of substernal chest pain, rating the pain 5 out of 10. What would be the priority action by the nurse?
- A. Administer the client's prescribed beta-blocker
- B. Administer nitroglycerin intravenously immediately
- C. Administer morphine
- D. Administer 325 mg of chewable aspirin immediately
Correct Answer: D
Rationale: Stable angina's oxygen pinch 5/10 pain bows to aspirin's antiplatelet punch, cutting clot risk fast, a priority over beta-blockers' slow rate drop. IV nitroglycerin's for MI, morphine's overkill, aspirin's chewed for quick absorption. Nurses hit this, easing ischemia, a front-line move in this chest squeeze.
Which set of classification values indicates the most extensive and progressed cancer?
- A. T1 N0 M0
- B. T10 N0 M0
- C. T1 N1 M0
- D. T4 N3 M1
Correct Answer: D
Rationale: TNM staging gauges cancer extent: T (tumor size), N (node involvement), M (metastasis). T4 N3 M1 marks the worst T4 signals a large, invasive tumor, N3 extensive nodal spread, M1 distant metastases, painting a picture of widespread, advanced disease. T1 N0 M0 is small, localized, no spread early stage. T10 isn't standard (likely T1), still less severe. T1 N1 M0 has minor nodal involvement, not extensive. T4 N3 M1's combination screams progression, guiding nurses to expect aggressive care or palliation, a stark contrast to earlier stages' hopeful prognosis, critical for planning in advanced cancer.
People with poorly controlled type 2 diabetes often show increased fasting blood glucose levels. Question: What causes these increased fasting blood glucose levels?
- A. Disturbed glucose uptake in adipose tissue due to insulin resistance
- B. Disturbed hepatic glucose uptake due to insulin resistance
- C. Disturbed suppression of hepatic glucose production by insulin
- D. Disturbed hepatic glucose uptake due to reduced insulin levels in portal blood
Correct Answer: C
Rationale: Type 2's fasting high liver pumps glucose, insulin can't hush it, resistance rules. Fat uptake's small, liver uptake's not key production's the leak nurses target this, a chronic dawn gush.
In the ACC/AHA 2017 Guideline for Hypertension, what is the cut off for hypertension diagnosis?
- A. 120/70 mmHg
- B. 130/80 mmHg
- C. 135/85 mmHg
- D. 140/90 mmHg
Correct Answer: B
Rationale: ACC/AHA 2017 130/80 tags hypertension, not old 140/90 or looser. Nurses gauge this chronic pressure shift.
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.
