A nurse is preparing to instill 840 mL of enteral nutrition via a client's gastrostomy tube over 24 hr using an infusion pump. The nurse should set the infusion pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)_mL/hr

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."

A) Weight and caloric intake:
While weight and caloric intake are important aspects of overall health assessment, they are not directly related to the administration of beta-adrenergic blocking agents. These medications primarily affect cardiovascular function, so assessing pulse and blood pressure is more pertinent.

B) Pulse and blood pressure:
This is the correct answer. Before administering beta-adrenergic blocking agents, it is essential to assess the client's pulse rate and blood pressure. Beta blockers work by blocking the effects of adrenaline, leading to a decrease in heart rate and blood pressure. Monitoring these vital signs helps determine the appropriateness of administering the medication and allows for adjustments based on the client's current cardiovascular status.

C) Serum sodium level:
Assessing serum sodium level is not typically necessary before administering beta-adrenergic blocking agents. While electrolyte imbalances can occur as a result of certain medications or health conditions, beta blockers do not directly affect serum sodium levels.

D) Serum albumin level:
Assessing serum albumin level is not specifically indicated before administering beta-adrenergic blocking agents. Serum albumin levels may be assessed in clients with certain conditions such as liver or kidney disease, but it is not a routine assessment before administering beta blockers.
