Nokea
What does the abbreviation DALY stand for?
- A. Definition of anticipated life years
- B. Diabetes-affected life years
- C. Disability-adjusted life years
- D. Disease-affected life years
Correct Answer: C
Rationale: DALY disability-adjusted life years tallies lost health, not diabetes alone or vague terms. Nurses use this, a chronic burden metric.

Which of the following management activities is not part of the nursing care of a patient with COPD?
- A. Achieving airway clearance and improving breathing patterns
- B. Ensuring the patient stays in bed and does not exert themselves causing increased dyspnoea
- C. Improving activity tolerance and assisting with lifestyle modification
- D. Monitoring and managing potential complications
Correct Answer: B
Rationale: COPD nursing pushes clearance, tolerance, and complication watch active goals. Bedrest flops deconditions, worsens breathlessness, a chronic care no-no nurses dodge.
An HIV-positive patient presents to the ED complaining of shortness of breath and non-productive cough. Chest x-ray shows diffuse interstitial infiltrates, and O2 saturation is 85% on room air. All of the following statements regarding this patient's probable diagnosis are TRUE, EXCEPT
- A. Pneumocystis carinii pneumonia (PCP) is the most common opportunistic infection in AIDS patients
- B. Pentamidine isothionate is an effective alternate therapy to TMP-SMX
- C. A normal chest x-ray rules out acute PCP infection
- D. 65% of patients relapse within 18 months
Correct Answer: H
Rationale: PCP top AIDS bug, pentamidine swaps TMP-SMX, relapse hits, steroids for hypoxia; normal CXR misses 20%. Nurses nix this chronic x-ray lie.
Patients on insulin therapy should receive essential education on the following EXCEPT:
- A. Insulin injection technique
- B. Recognition and self-management of hypoglycaemia
- C. Sick day management
- D. Stopping all oral hypoglycaemic agents
Correct Answer: D
Rationale: Insulin education builds control technique, hypo spotting, sick days, and driving safety are musts, ensuring delivery, crisis handling, and road smarts. Stopping all oral agents isn't universal; many stay on metformin or SGLT-2s for synergy, not a blanket rule. Tailored plans keep or ditch orals, dodging this absolute. Clinicians teach what fits, not a one-size purge, a nuanced chronic care tweak over rigid cuts.
A nurse is caring for a client diagnosed with peripheral artery disease. Which of the following is a common assessment finding?
- A. 4+ pedal pulses
- B. 3+ pedal pulses
- C. Bounding pulses in all 4 extremities
- D. 1+ pedal pulses
Correct Answer: D
Rationale: Peripheral artery disease (PAD) clogs arteries, slashing flow 1+ pedal pulses (weak, thready) are typical, reflecting ischemia below blockages. 4+ or 3+ pulses (strong) contradict PAD's hypoperfusion; bounding pulses suggest hyperdynamic states, not occlusion. Nurses expect weak pulses, checking for pain or pallor, key to tracking PAD's limb-threatening march, guiding interventions like revascularization.
Percutaneous cervical cordotomy:
- A. Is performed under general anaesthesia.
- B. Occurs by entry of a needle into the intervertebral foramen between cervical vertebrae C4 and C5.
- C. Involves thermoablation of the anterior spinothalamic tract.
- D. Is performed on the same side as the pain.
Correct Answer: C
Rationale: Percutaneous cervical cordotomy (PCC) relieves cancer pain via targeted nerve destruction. It's done under local anesthesia with sedation, not general, to monitor patient response (e.g., pain relief, side effects) during stimulation. The needle enters at C1-C2, not C4-C5, targeting the lateral spinothalamic tract contralateral to the pain not the anterior tract explicitly, though terminology varies. Thermoablation destroys pain fibers, confirmed by test stimulation. It's performed opposite the pain side due to crossed spinothalamic pathways. Complete numbness isn't typical; sensory loss is partial. Thermoablation's specificity using radiofrequency to interrupt pain transmission defines PCC's efficacy, minimizing damage to adjacent motor tracts while achieving analgesia.
