The Barker hypothesis describes the relationship between birth weight and the development of diseases. Question: Which relationship is correct?
- A. High birth weight is associated with a reduced risk of obesity, diabetes and/or cardiovascular disease at a later age
- B. High birth weight is associated with an increased risk of obesity, diabetes and/or cardiovascular disease at a later age
- C. Low birth weight is associated with a reduced risk of obesity, diabetes and/or cardiovascular disease at a later age
- D. Low birth weight is associated with an increased risk of obesity, diabetes and/or cardiovascular disease at a later age
Correct Answer: D
Rationale: Barker's call low birth weight scars metabolism, upping later obesity, diabetes, heart woes. High weight leans risky too, but low's the proven chronic link nurses track this fetal echo.

Appropriate statements concerning radiology and trauma interventional radiology include:
- A. To rule out injury of the cervical spine in the unconscious patient, application of a protocol involving a computed tomography (CT) scan to the neck is recommended.
- B. A FAST (Focused Assessment with Sonography for Trauma) scan is a specific investigation for assessment of intraperitoneal bleeding.
- C. In a patient who is persistently hypotensive in the emergency department despite adequate fluid resuscitation, radiological interventions to treat bleeding caused by a pelvic fracture are not recommended.
- D. Interventional radiology has a role in the management of injuries to the liver, kidney and spleen.
Correct Answer: A
Rationale: Trauma radiology optimizes diagnosis and intervention. CT is the gold standard for cervical spine assessment in unconscious patients, per NICE guidelines, offering high sensitivity for fractures/ligamentous injury versus plain films. FAST scans detect free fluid (e.g., blood) intraperitoneally but lack specificity positive findings need confirmation (e.g., CT). Persistent hypotension with pelvic fracture warrants interventional radiology (e.g., embolization), not dismissal contrary to the statement. Interventional radiology manages solid organ injuries (liver, kidney, spleen) via embolization, reducing surgical need. Staffing in radiology matches theatre for critical cases. CT's diagnostic precision in cervical spine trauma ensures timely, accurate management, critical in unconscious patients where clinical exam is unreliable.
In which illness can hydrophobia be seen?
- A. tetanus
- B. malaria
- C. rabies
- D. EBV
Correct Answer: C
Rationale: Hydrophobia rabies' brain hates water, not tetanus' clench, malaria's sweat, EBV's glands, or HSV's sores. Nurses clock this chronic rabies red flag.
An oncology patient will begin a course of chemotherapy and radiation therapy for the treatment of bone metastases. What is one means by which malignant disease processes transfer cells from one place to another?
- A. Adhering to primary tumor cells
- B. Inducing mutation of cells of another organ
- C. Phag projecting healthy cells
- D. Invading healthy host tissues
Correct Answer: D
Rationale: Bone mets mean cancer's invaded malignant cells burrow into nearby tissues, breaking barriers to spread, a hallmark of metastasis. They don't just stick to the primary (adhesion's weak), mutate distant cells (that's not how it rolls), or eat healthy ones (phagocytosis is immune, not cancer). Invasion's the ticket cells chew through matrix, hit lymph or blood, and land in bones. Nurses in oncology spotlight this, tying it to why radiation's aimed at those hotspots, slowing the creep.
The Pulmonary rehabilitation program consists of several specific components. Which of the following are not a part of the program?
- A. Education and self-management
- B. Exercise training
- C. Coping measures to relieve anxiety, depression and changes in behaviour
- D. Spirometry
Correct Answer: D
Rationale: Pulmonary rehab builds COPD strength education, exercise, coping tools for mind and mood, all in. Spirometry's a test, not therapy diagnoses, doesn't train. Nurses skip it here, a chronic fix's focus.
Autonomic neuropathies affecting people with chronic diabetes affect many body systems. Which of the following is not a clinical manifestation of this problem?
- A. Tachycardia
- B. Mental confusion
- C. Urinary retention
- D. Anhidrosis
Correct Answer: B
Rationale: Diabetes' nerve mess fast heart, pee stalls, no sweat autonomic signs. Confusion's brain sugar or stroke, not this. Nurses clock these, a chronic nerve quirk.
