Nokea
Regarding infective endocarditis in an IVDU
- A. Usually presents with fever and respiratory symptoms
- B. Usually involves the mitral valve
- C. The commonest organism is staph epidermidis
- D. Negative blood cultures exclude the diagnosis
Correct Answer: A
Rationale: IVDU endocarditis fever, lung emboli from tricuspid, not mitral, Staph aureus, cultures miss some. Nurses hear this chronic right-side roar.

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.
After receiving the hand-off report, which client should the oncology nurse see first?
- A. Client who is afebrile with a heart rate of 108 beats/min
- B. Older client on chemotherapy with mental status changes
- C. Client who is neutropenic and in protective isolation
- D. Client scheduled for radiation therapy today
Correct Answer: B
Rationale: In oncology nursing, prioritizing care is critical due to the complexity of cancer patients' conditions. An older client on chemotherapy with mental status changes is the priority because this could signal sepsis or infection, especially since chemotherapy-induced neutropenia often masks typical signs like fever in the elderly. Mental confusion might be the only early clue, and delayed assessment could lead to rapid deterioration or death. A heart rate of 108 beats/min without fever suggests tachycardia, possibly from dehydration or anxiety, but it's less urgent without other red flags. A neutropenic client in isolation needs monitoring, but no acute change is noted. The client scheduled for radiation has a planned treatment, not an immediate crisis. Assessing the older client first allows the nurse to rule out or address a life-threatening issue, aligning with the principle of prioritizing unstable patients in acute care settings.
The definition of Chronic Heart Failure is:
- A. Failure of the heart to adequately pump blood to the body.
- B. Long-term inability of the heart to meet metabolic demands required to maintain homeostasis.
- C. Prolonged enlargement of the left ventricle impacting on the contractility of the muscle.
- D. Long term fluid build-up, causing increase in blood volume and reducing the ability of the heart to maintain blood flow.
Correct Answer: B
Rationale: Chronic heart failure (CHF) is a syndrome, not a singular defect. Failure to pump adequately describes acute failure but lacks chronicity's scope. CHF is the heart's prolonged inability to meet metabolic demands for oxygen and nutrients, disrupting homeostasis per Farrell (2017) encompassing systolic (reduced ejection) and diastolic (impaired filling) dysfunction. Left ventricular enlargement may occur (e.g., dilated cardiomyopathy), but it's a cause or result, not the definition; contractility varies. Fluid buildup (congestion) is a feature, not the essence blood volume rises secondary to neurohormonal activation (e.g., renin-angiotensin system), not as the primary failure. The metabolic demand focus captures CHF's systemic impact fatigue, edema, dyspnea reflecting chronic adaptation failure over structural or fluid-centric descriptions.
Which of the following are the characteristics of masked hypertension?
- A. High home BP more than three days in a week
- B. Normal office BP and high home BP
- C. High office BP and normal home BP
- D. Normal office BP and normal home BP
Correct Answer: B
Rationale: Masked hypertension hides normal office readings (<140/90) clash with high home BP (>135/85), dodging detection, yet hiking cardiovascular risk. High home BP alone lacks context; high office with normal home is white-coat hypertension. Normal both ways is healthy; high both is overt hypertension. This sneaky pattern demands home monitoring to unmask, as office calm misses real-world spikes, pushing clinicians to dig deeper for treatment, a silent chronic threat exposed by dual settings.
Which is FALSE regarding PCP pneumonia in AIDS?
- A. it is usually only seen when the CD4 count <200
- B. prophylaxis should be given in all pts with CD4 count <200
- C. CXR characteristically shows bilateral diffuse infiltrates
- D. Once a patient has had it they are unlikely to get it again
Correct Answer: D
Rationale: PCP relapse haunts AIDS CD4 <200 stays vulnerable, not a one-off. Prophylaxis holds below 200, CXR's diffuse or blank 20%, all true. Nurses know this chronic lung leech bites again sans lifelong guard.
