Which of the following terms is used when an adult has a pulse rate of 110 to 140 beats per minute?

Client A has normal vital signs except for a mild fever, no urgent intervention needed.

Client B shows mild tachycardia and increased respiratory rate, but oxygen saturation and blood pressure remain stable, requires monitoring but not immediate action.

Client C has fever, tachycardia, and tachypnea, suggesting infection or dehydration. While assessment is needed, the patient is not in immediate distress compared to Client D.

Client D requires immediate nursing intervention due to the following critical findings: Bradycardia which may indicate poor perfusion, conduction abnormalities, or medication side effects, bradypnea can signal respiratory depression or impending failure, hypotension suggests shock or decreased perfusion, which may lead to organ failure and hypoxia, oxygen saturation below 90% is a critical finding and requires immediate intervention.

A. Always take the patient's blood pressure manually using a sphygmomanometer. While manual BP measurements can be more accurate, they are not the priority intervention for orthostatic hypotension, which primarily involves position changes and fall prevention.
B. Monitor the patient's neurological status carefully for symptoms of a stroke. Orthostatic hypotension can cause dizziness or fainting, but it is not a direct cause of stroke. Neurological assessment is important if symptoms arise but is not the primary intervention.
C. Assist the patient to sit and stand slowly when getting out of bed. Orthostatic hypotension causes a sudden drop in blood pressure upon standing, increasing the risk of falls and syncope. The priority action is to help the patient transition slowly from lying to sitting and standing to allow the body to adjust.
D. Check the patient's blood pressure on a lower extremity using a thigh-sized cuff. Lower extremity BP measurements are not standard for managing orthostatic hypotension. Blood pressure should be checked in both lying, sitting, and standing positions to monitor for significant drops.
