Nokea
Oxygen therapy is prescribed as long term continuous therapy (more than 15 hours/day) to
- A. Improve QOL, reduce pulmonary arterial pressure and dyspnoea and increase survival
- B. Reduce respiratory effort caused by the damage to airways and lung parenchyma
- C. Increase patient comfort, reduce cyanosis and assist with sleeping
- D. Relieve anxiety related to breathlessness and reassure carer that the patient is receiving adequate oxygenation
Correct Answer: A
Rationale: Long-term O2 in COPD lifts life cuts lung pressure, eases breath, boosts survival, a proven lifeline. Effort's not the target; comfort's secondary; anxiety's a perk, not goal. Nurses push this, a chronic game-changer.

Which antibiotic is not recommended as first line therapy for the associated bug?
- A. legionella - erythromycin
- B. chlamydia psittaci - doxycycline
- C. chlamydia pneumoniae - doxycycline
- D. mycoplasma pneumoniae - roxithromycin
Correct Answer: C
Rationale: Chlamydia pneumoniae doxycycline's gold, not erythromycin, roxi, or others mispaired. Nurses tweak this chronic lung fix.
While performing an admission assessment for a client, the nurse notes that the client has varicose veins with ulcerations and lower extremity edema with a report of a feeling of heaviness. Which of the following nursing diagnoses should the nurse identify as the priority in the client's care?
- A. Ineffective peripheral tissue perfusion
- B. Alteration in body image
- C. Impaired skin integrity
- D. Alteration in activity tolerance
Correct Answer: C
Rationale: Varicose veins with ulcerations, edema, and heaviness scream venous stasis impaired skin integrity tops the list as open sores risk infection, a pressing threat needing immediate wound care. Ineffective perfusion drives the issue, but skin breakdown's acuity trumps. Body image matters emotionally, less urgently. Activity tolerance lags behind active complications. Nurses prioritize skin integrity, addressing ulcers' vulnerability, a direct care focus to halt deterioration in this chronic venous picture, aligning with safety and healing goals.
Certain drug classes may cause harm in patients with symptomatic (NYHA classes II-IV) reduced ejection Heart failure (HFrEF), and thus should be avoided. If they are strongly indicated, they are to be used with caution, and with close monitoring. Such drugs include all of the following except:
- A. Thiazolidinediones (glitazones, e.g., pioglitazone, rosiglitazone)
- B. Nonsteroidal anti-inflammatory drugs and COX-2 inhibitors
- C. Nutritional supplements (e.g., coenzyme Q10, carnitine, taurine, and antioxidants)
- D. Non-dihydropyridine calcium-channel blockers (verapamil, diltiazem)
Correct Answer: C
Rationale: HFrEF hates fluid and strain glitazones swell, NSAIDs tank kidneys, verapamil/diltiazem slow too much, trastuzumab trashes hearts. Supplements like CoQ10? Neutral or helpful, not harmful, a safe outlier. Clinicians dodge the rest, easing chronic pump woes, not this add-on.
NASH contributes to the risk of cardiovascular disease via which mechanism in the liver?
- A. Reduced production of VLDL
- B. Reduced production of glucose
- C. Increased production of CRP
- D. Increased production of HDL
Correct Answer: C
Rationale: NASH ups heart risk CRP, inflammation's flag, flares from liver, not VLDL drop, glucose dip, or HDL boost. Nurses spot this, a chronic CV spark.
What is the cut-off of blood pressure for the diagnosis of hypertension that is recommended by MOH Clinical Practice Guideline?
- A. 120/70 mmHg
- B. 125/75 mmHg
- C. 130/70 mmHg
- D. 140/90 mmHg
Correct Answer: D
Rationale: MOH guidelines hold hypertension at 140/90 mmHg, a conventional cutoff balancing sensitivity and specificity for diagnosis in primary care, aligning with global norms like WHO. Lower thresholds 120/70, 125/75, 130/70, 135/80 catch prehypertension or align with newer AHA standards, but MOH sticks to 140/90 for actionable clarity, triggering treatment to curb stroke or heart risks. This higher bar avoids overdiagnosis in resource-stretched settings, ensuring focus on clear disease, a practical call for managing chronic vascular load.
