Which of the following is NOT involved with weight regulation?
- A. The hypothalamic arcuate nucleus (ARC)
- B. The lateral geniculate nucleus
- C. The lateral hypothalamic area
- D. The paraventricular nucleus
Correct Answer: B
Rationale: Weight's brain game ARC, lateral hypothalamus, paraventricular nucleus, and solitary tract tunes hunger, satiety, and energy via hormones and gut signals. The lateral geniculate nucleus, a vision hub, sits out, irrelevant to food's dance. Clinicians map this circuitry, targeting obesity's roots, a chronic fix sidestepping eyeballs.

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.
Regarding HIV/AIDS
- A. Shingles, seborrhoeic dermatitis and recurrent HSV infections are typical of early infection
- B. A CD4 count of 1.0 x 10^9/L is associated with late stage AIDS
- C. Pre and post test counselling for HIV serology is now no longer mandatory
- D. Pneumococcus is a more likely pathogen than TB in AIDS patients with pneumonia
Correct Answer: D
Rationale: HIV early skin woes, CD4's units flop, counseling holds, TB trumps pneumococcus, toxo hits brain. Nurses chase this chronic lung truth.
A general practitioner (GP) advises an overweight patient to go to the gym to work out. Question: This advice is an example of which type of prevention?
- A. Primary prevention
- B. Secondary prevention
- C. Tertiary prevention
- D. Quaternary prevention
Correct Answer: A
Rationale: Gym nudge for overweight primary, stops diabetes before it starts, not screening or late fixes. Nurses push this, a chronic preemptive strike.
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.
Which of the following should be not be routinely performed for patients with suspected non-alcoholic fatty liver disease?
- A. Liver biopsy
- B. Imaging studies like US scan
- C. Fasting lipids
- D. Fasting glucose
Correct Answer: A
Rationale: Liver biopsy, while diagnostic for NAFLD/NASH, isn't routine due to invasiveness and risks, reserved for unclear cases or staging needs, per AASLD. Ultrasound (fatty liver detection), fasting lipids, glucose, and liver function tests are non-invasive, routine screens for metabolic risk and diagnosis confirmation. This approach optimizes chronic disease evaluation safely.
