Question 4 of 5
If the blood in the subclavian vein of the chest had a pressure of 25 mm Hg and the pressure of the superior vena cava that drains the subclavian had a pressure of 15 mm Hg, the right atrium would have a pressure of:
Correct Answer: C
Rationale: Blood flows from higher to lower pressure. The subclavian vein (25 mm Hg) drains into the superior vena cava (15 mm Hg), which then enters the right atrium. Thus, the right atrial pressure must be less than 15 mm Hg to allow flow, typically around 0-8 mm Hg.
Question 5 of 5
Which action should the nurse include in the plan of care when caring for a patient admitted with acute decompensated heart failure (ADHF) who is receiving nesiritide (Natrecor)?
Correct Answer: A
Rationale: Nesiritide is a potent arterial and venous dilator, and the major adverse effect is hypotension. Because the patient is likely to have orthostatic hypotension, the patient should not be encouraged to ambulate. Nesiritide does not require titration and is used for ADHF but not in a home setting.
