A nurse is teaching a newly licensed nurse about orthostatic hypotension. Which of the following information should the nurse include?
Orthostatic hypotension is indicated by a decrease in diastolic blood pressure of 5 mm Hg.
Orthostatic hypotension is indicated by a decrease in systolic blood pressure of 5 mm Hg.
Orthostatic hypotension increases a client's risk of a fall.
Orthostatic hypotension increases a client's risk of a pulmonary emboli.
The Correct Answer is C
A) Orthostatic hypotension is indicated by a decrease in diastolic blood pressure of 5 mm Hg:
Orthostatic hypotension is typically defined by a decrease in systolic blood pressure of 20 mm Hg or more or a decrease in diastolic blood pressure of 10 mm Hg or more within three minutes of standing up. Diastolic blood pressure alone is not the primary indicator of orthostatic hypotension.
B) Orthostatic hypotension is indicated by a decrease in systolic blood pressure of 5 mm Hg:
While a decrease in systolic blood pressure is a component of orthostatic hypotension, the criterion for diagnosing orthostatic hypotension is a decrease in systolic blood pressure of 20 mm Hg or more or a decrease in diastolic blood pressure of 10 mm Hg or more within three minutes of standing up.
C) Orthostatic hypotension increases a client's risk of a fall:
This statement is correct. Orthostatic hypotension, characterized by a sudden drop in blood pressure upon standing, can lead to dizziness and lightheadedness, increasing the risk of falls, particularly in older adults.
D) Orthostatic hypotension increases a client's risk of a pulmonary emboli:
Orthostatic hypotension is not directly associated with an increased risk of pulmonary emboli. Pulmonary embolism is a separate condition involving a blockage in the pulmonary artery or its branches, typically caused by a blood clot."

Correct Answer is ["125"]
Explanation
Here's the breakdown of the calculation:
Total volume of fluid to infuse (mL): 1000 mL
Infusion time (hours): 8 hours
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours)
Flow rate (mL/hr) = 1000 mL / 8 hours = 125 mL/hr (round to nearest whole number as requested)
Therefore, the nurse should program the pump to deliver 125 mL/hr.
Correct Answer is A
Explanation
A) Pulmonary artery:
The pulmonary artery carries deoxygenated blood from the right ventricle of the heart to the lungs for oxygenation. This is the correct starting location for blood flow from the heart to the lungs in the pulmonary circulation.
B) Left atrium:
The left atrium receives oxygenated blood from the pulmonary veins and pumps it into the left ventricle, not from the right ventricle to the lungs.
C) Left ventricle:
The left ventricle pumps oxygenated blood into the systemic circulation, not from the right ventricle to the lungs.
D) Pulmonary veins:
The pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart, not from the right ventricle to the lungs."
