- A. Pulmonary artery wedge pressure > 15 mm Hg
- B. Right ventricular systolic pressure > 36 mm Hg
- C. Diastolic pressure gradient < 7 mm Hg
- D. Pulmonary vascular resistance > 3 Wood units
Correct Answer: A
Rationale: Isolated post-capillary pulmonary hypertension is defined by a pulmonary artery wedge pressure greater than 15 mm Hg.

A pediatric patient is scheduled for a noninvasive procedure to determine if his heart is structurally normal and to localize a murmur. What diagnostic test does the nurse anticipate?
- A. Barium swallow
- B. Chest x-ray
- C. Electrocardiogram
- D. Echocardiogram
Correct Answer: D
Rationale: Echocardiography is a noninvasive procedure that localizes murmurs and determines if the heart is structurally normal.
Acute bronchiolitis is associated with:
- A. A higher incidence in infants than in school children
- B. The production of copious amounts of purulent sputum
- C. Widespread fine crackles
- D. A polymorphonuclear leucocytosis
Correct Answer: A
Rationale: Acute bronchiolitis is more common in infants and is associated with fine crackles. Purulent sputum and polymorphonuclear leucocytosis are not typical features.
Regarding a supracristal VSD, the following are true EXCEPT
- A. incidence is higher in Asian children
- B. complicated by aortic insufficiency in 50-90% of patients
- C. aortic insufficiency is most often not recognized until late in the lst decade of life
- D. murmur of a supracristal VSD is usually heard at the mid to upper left sternal border
Correct Answer: D
Rationale: Closure of asymptomatic supracristal VSDs at the time of diagnosis is not recommended.
While planning care for a client with carpal tunnel syndrome, the nurse identifies a collaborative problem of pain. what is the etiology of this problem?
- A. Irritation of nerve endings
- B. Diminished blood flow
- C. Ischemic tissue changes
- D. Compression of a nerve
Correct Answer: D
Rationale: Carpal tunnel syndrome is caused by compression of the median nerve, leading to pain and other symptoms.
The jugular venous pressure (JVP) has a predictable relationship with pulmonary artery wedge pressure (PAWP). A JVP of >12 mm Hg predicted PAWP >22 mm Hg by 88% in which of the following trials?
- A. BNP
- B. ESCAPE
- C. EVEREST
- D. EMPA REG
Correct Answer: B
Rationale: The ESCAPE trial studied the effectiveness of therapies in patients with advanced heart failure and showed that elevated JVP was correlated with high pulmonary artery wedge pressures.
