Prescription of long term oxygen therapy has some very strict guidelines. In order to qualify for this treatment, the patient has to:
- A. Be admitted to hospital 3 times within a 12 month time frame with acute exacerbation of COPD
- B. Demonstrate a significant impairment of QOL because of dyspnoea and decreased exercise capacity
- C. Have very high levels of anxiety which impact on their ability to self-manage and increase stress on carer
- D. Have a diagnosis of severe COPD with PaO2 of >55 mmHg, or evidence of tissue hypoxia and end organ damage
Correct Answer: D
Rationale: O2's lifeline demands proof severe COPD with PaO2 ≤55 mmHg or hypoxia's organ bite, a strict cut. Admissions, QOL dips, anxiety don't seal it hypoxemia does. Nurses gatekeep this, a chronic oxygen rule.

The nurse on a bone marrow transplant unit is caring for a patient with cancer who is preparing for HSCT. What is a priority nursing diagnosis for this patient?
- A. Fatigue related to altered metabolic processes
- B. Altered nutrition: less than body requirements related to anorexia
- C. Risk for infection related to altered immunologic response
- D. Body image disturbance related to weight loss and anorexia
Correct Answer: C
Rationale: HSCT obliterates marrow, tanking immunity risk for infection soars as neutrophils vanish, making it the top nursing diagnosis pre-transplant. Sepsis can kill fast in this window, unlike fatigue or nutrition issues, which matter but aren't immediate threats. Body image might nag later with hair loss or weight shifts, but infection's the killer to watch. Nurses lock in on this, driving strict isolation and monitoring, knowing a stray germ could derail everything in oncology's high-stakes transplant game.
A 58-year-old man with a known history of heart failure from cardiomyopathy, with an ejection fraction of 30 percent returns for a 3-week follow-up visit after being started on frusemide 40 mg od for increasing symptoms of dyspnea. Since starting frusemide, his symptoms have returned to baseline and he has lost 3 kg. He is maintained on guideline-directed medical therapy for heart failure including sacubitril/valsartan 97 mg/103 mg BD, carvedilol 12.5 mg BD, Simvastatin 40 mg ON, and aspirin 81 mg OD. His physical examination reveals: blood pressure of 128/80 mmHg, regular heart rate of 78 bpm, respiratory rate of 18 breaths/min, and room air oxygen saturation of 96 percent with no saturation decrease with hallway ambulation. He has no peripheral edema. A clinic electrocardiogram reveals a left bundle branch block with a QRS duration of >150 msec. What would be the most appropriate next step in management?
- A. Refer him to an electrophysiologist
- B. Discontinue the sacubitril/valsartan 97 mg/103 mg BD
- C. Change his diuretic to spironolactone 25 mg OD
- D. Increase the frusemide to 40 mg BD
Correct Answer: A
Rationale: HFrEF at 30% EF with LBBB >150 msec stabilized on meds hints at dyssynchrony, ripe for cardiac resynchronization therapy, so an electrophysiologist's next. Ditching sacubitril/valsartan or swapping diuretics lacks cause; upping frusemide or re-echoing waits. Clinicians tap this referral, boosting chronic pump sync, a guideline nod.
A hospitalized patient who has received chemotherapy for leukemia develops neutropenia. Which observation by the nurse would indicate a need for further teaching?
- A. The patient ambulates several times a day in the room
- B. The patient's visitors bring in some fresh peaches from home
- C. The patient cleans with a warm washcloth after having a stool
- D. The patient uses soap and shampoo to shower every other day
Correct Answer: B
Rationale: Neutropenia post-chemo low neutrophils craves germ-free zones; fresh peaches from home carry bacteria, a teaching gap as raw produce risks infection in this immune-wrecked state. Ambulation's safe, hygiene's spot-on washcloths and showers cut germs. Nurses reteach, banning unwashed fruit, a vital shield in leukemia's neutropenic peril, ensuring clients grasp this microbial minefield.
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.
The most frequent aerobic organism isolated in human bites is
- A. Pasteurella multocida
- B. Eikenella corrodens
- C. Haemophilus aphrophilus
- D. Streptococcus viridans
Correct Answer: D
Rationale: Human bites Strep viridans, mouth's norm, tops aerobes, not Pasteurella's dog, Eikenella's anaerobe, or rare Haemophilus, Capno. Nurses bite this chronicå£è…” champ.
