In the clinical assessment of heart failure, which of the following is FALSE?
- A. Jugular venous distention, an S1 heart sound, and non-displaced apical impulse significantly increase the likelihood of the diagnosis
- B. Hypertension, CAD, and valvular disease are the most common causes
- C. Fatigue, weakness, dyspnea, orthopnea, paroxysmal nocturnal dyspnea, and edema are common symptoms
- D. Cardiomegaly on CXR is helpful in supporting the diagnosis
Correct Answer: A
Rationale: Jugular venous distention and edema suggest heart failure, but S1 (normal first sound) and non-displaced apical impulse don't increase diagnostic likelihood S3 or displaced impulse do, per clinical criteria. Common causes (HTN, CAD, valvular disease), symptoms, and cardiomegaly on CXR are true. ECG is vital. This corrects diagnostic focus in chronic HF assessment.

Characteristics of acute pain do not include:
- A. Recent onset
- B. Attributable to specific injury or disease
- C. Lasts from a few minutes to less than 6 months
- D. Unable to be relieved by analgesia
Correct Answer: D
Rationale: Acute pain fresh, tied to harm, short-lived yields to pills, not stubborn. Nurses spot this, a chronic pain foil.
Which is the most common organism infecting coral cuts?
- A. non-cholera vibrio
- B. mycobacterium marinum
- C. aeromonas species
- D. strep pyogenes
Correct Answer: D
Rationale: Coral cuts strep pyogenes streaks in, not vibrio, mycobacterium, aeromonas, or E. coli's swim. Nurses hit this chronic skin ripper.
A patient who is scheduled for a breast biopsy asks the nurse the difference between a benign tumor and a malignant tumor. Which answer by the nurse is correct?
- A. Benign tumors do not cause damage to other tissues.
- B. Benign tumors are likely to recur in the same location.
- C. Malignant tumors may spread to other tissues or organs.
- D. Malignant cells reproduce more rapidly than normal cells.
Correct Answer: C
Rationale: Malignant tumors metastasize spreading to distant sites via lymph or blood unlike benign ones, which stay put. That's the key split. Benign tumors can still mess up nearby tissues by pressing on them (e.g., a benign meningioma squeezing brain), so A's off. B's wrong benign tumors rarely recur if fully removed; malignancy's more prone to that. D's a myth malignant cells don't always divide faster; some, like chronic leukemia, creep along. Nurses in oncology nail this down for patients facing biopsies, like this breast case, where fear of spread drives the question. Explaining metastasis clarifies why malignant's scarier it's not just growth, it's invasion, a game-changer for prognosis and treatment.
Which of the following condition has low risk of progression to liver cirrhosis:
- A. Hepatic steatosis
- B. Hepatic steatohepatitis
- C. Hepatic steatohepatitis with fibrosis
- D. Chronic hepatitis
Correct Answer: A
Rationale: Steatosis fat sits, low cirrhosis odds; steatohepatitis, fibrosis, chronic, booze burn scar. Nurses mark this chronic liver lite.
A 30yr NZ man goes to PNG, takes 300 mg chloroquine weekly for 2 weeks prior and 4 weeks post his trip. 3/12 later gets febrile/sweats/maleana with malaria parasites on film. The following is true
- A. He took 1/2 the normal dose of chloroquine
- B. If he took primaquine for 2/52 this wouldn't have happened
- C. Assume chloroquine resistance and treat accordingly
- D. This is probably p. falciparum
Correct Answer: C
Rationale: PNG malaria chloroquine's 250 mg norm, resistance rife, not dose, primaquine, or falciparum lock. Nurses switch this chronic resistant fix.
