Non modifiable risk factors for developing chronic illness includes
- A. Tobacco smoking
- B. Political factors
- C. Family history
- D. High blood pressure
Correct Answer: C
Rationale: Chronic illness risk splits family history's locked in, genes dictating diabetes or heart disease odds, unchangeable. Smoking's a choice, modifiable; politics shape systems, not biology; high BP's treatable, not fixed. Nurses flag this genetic thread, focusing prevention elsewhere, a chronic cornerstone where heritage trumps habits or policy.

The single most effective intervention to reduce the risk of developing COPD and stop its progression is
- A. Increased physical activity
- B. Prompt intervention for chest infection
- C. Smoking Cessation
- D. Avoidance of indoor and outdoor pollutants
Correct Answer: C
Rationale: COPD's king fix quit smoking slashes risk and stalls damage, trumping exercise, infection zaps, or pollution dodges. It's the top toxin, 80% of cases, a chronic killer nurses chase down hard.
During artificial ventilation in a patient with chronic obstructive pulmonary disease, air trapping:
- A. Leads to hypotension when venous return is reduced significantly.
- B. Is likely to be present when the capnogram fails to reach a plateau in expiration.
- C. May be reduced by using a low respiratory rate.
- D. Is reduced by decreasing the ratio of inspiratory time to expiratory time.
Correct Answer: A
Rationale: Air trapping in COPD during mechanical ventilation occurs due to incomplete exhalation from airway obstruction, leading to intrinsic positive end-expiratory pressure (auto-PEEP). This increases intrathoracic pressure, compressing the vena cava and reducing venous return, which can cause hypotension a critical complication. A capnogram failing to plateau suggests prolonged exhalation, consistent with air trapping, but it's a diagnostic sign, not a consequence. A low respiratory rate allows more exhalation time, reducing air trapping, while decreasing the inspiratory-to-expiratory time ratio (e.g., shortening inspiration) similarly helps by extending exhalation. Positive end-expiratory pressure (PEEP) can exacerbate air trapping if excessive, but its effect depends on levels used. Hypotension from reduced venous return is a direct physiological result of severe air trapping, making it the most definitive statement in this context.
Diabetes is associated with pathophysiological mechanisms that contribute to the development of cardiovascular events. Question: What is the approximate percentage of diabetes patients who also have hypertension?
- A. 25%
- B. 50%
- C. 75%
- D. 100%
Correct Answer: C
Rationale: Diabetes and hypertension 75% overlap, sugar and pressure tag-team hearts. Nurses watch this, a chronic duo hit.
A 60-year-old patient with a diagnosis of prostate cancer is scheduled to have an interstitial implant for high-dose radiation (HDR). What safety measure should the nurse include in this patient's subsequent plan of care?
- A. Limit the time that visitors spend at the patient's bedside
- B. Teach the patient to perform all aspects of basic care independently
- C. Assign male nurses to the patient's care whenever possible
- D. Situate the patient in a shared room with other patients receiving brachytherapy
Correct Answer: A
Rationale: HDR implants (brachytherapy) emit radiation limiting visitor time (e.g., 30 min) cuts exposure risk. Self-care's nice but not safety-driven. Gender's irrelevant pregnant staff avoid, not males. Shared rooms up exposure, not safety. Nurses in oncology enforce this, shielding others while the source's active, a radiation rule of thumb.
What is the relationship between hyperlipidaemia and non-alcoholic steatohepatitis (NASH)?
- A. Hyperlipidaemia contributes to the development of NASH
- B. NASH contributes to the development of hyperlipidaemia
- C. There is no relationship between hyperlipidaemia and NASH
- D. Answers 1 and 2 are correct
Correct Answer: D
Rationale: NASH and hyperlipidaemia dance both ways high lipids pile fat, NASH pumps them back, a chronic loop. No split or null fits nurses track this lipid-liver ping-pong.
