The client has been ordered a nonselective beta-blocking agent called propranolol, PO. Propranolol is used in the treatment of which disorders (Select All that Apply.)

A) Temperature and respiratory rate:
While monitoring temperature and respiratory rate are important aspects of a comprehensive assessment, they are not the priority assessments before administering metoprolol. Metoprolol is a beta-blocker primarily used to lower heart rate and blood pressure, so assessing the client's heart rate and blood pressure is more relevant.

B) Heart rate and blood pressure:
This is the correct answer. Before administering metoprolol, it is essential to assess the client's heart rate and blood pressure. Metoprolol is a beta-blocker medication that primarily affects heart rate and blood pressure. Monitoring these vital signs helps ensure that the medication is administered safely and effectively.

C) Level of consciousness and pain level:
Assessing the client's level of consciousness and pain level are important aspects of nursing care, but they are not the priority assessments before administering metoprolol. These assessments may be relevant depending on the client's overall condition and specific care needs, but they are not directly related to the action or side effects of metoprolol.

D) Oxygen saturation and respiratory rate:
Monitoring oxygen saturation and respiratory rate are important aspects of respiratory assessment, but they are not the priority assessments before administering metoprolol. While metoprolol can affect respiratory function as a potential side effect, its primary action is on heart rate and blood pressure. Therefore, assessing heart rate and blood pressure are more pertinent before administering this medication.

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."
