When performing venipuncture, the tourniquet must not remain on the arm for more than ______________ at a time

Answers

Answer 1

When performing venipuncture, the tourniquet must not remain on the arm for more than a recommended time limit.

The recommended time limit for the tourniquet to remain on the arm during venipuncture varies but is generally around 1 to 2 minutes. It is crucial to follow this time limit to prevent complications and ensure patient safety.

The purpose of the tourniquet is to apply pressure on the veins, causing them to become more prominent and facilitating the process of locating a suitable vein for venipuncture. However, leaving the tourniquet on for too long can have negative consequences.

Extended application of the tourniquet can lead to venous congestion and stasis, which may alter the composition of the blood sample and affect test results. Prolonged pressure can also cause discomfort and potential tissue damage, especially in patients with compromised circulation or fragile veins.

Therefore, it is essential for healthcare professionals performing venipuncture to adhere to the recommended time limit for tourniquet application. This helps ensure accurate and reliable blood sample collection while minimizing the risk of complications or discomfort for the patient.

Answers

In the chronic pulmonary disease emphysema, the alveolar walls lose their elasticity, become overinflated, and eventually rupture.

Emphysema is a lung condition that develops when the alveolar walls in our lungs are harmed. It is possible for an obstruction (blockage) to form, trapping air in your lungs. It is a gradual degenerative disease, that affects the suppleness of the alveolar walls, which ultimately affects the lungs' capacity to exhale air.

Which is the most common motor dysfunction seen in clients diagnosed with stroke?

Answers

The most common motor dysfunction seen in clients diagnosed with stroke is hemiparesis, which refers to weakness or paralysis on one side of the body.

Hemiparesis is a motor dysfunction characterized by weakness or paralysis on one side of the body, typically affecting the limbs. It is often seen in clients diagnosed with stroke, which is a condition caused by the interruption of blood supply to the brain.

The brain damage resulting from a stroke can disrupt the normal functioning of motor pathways, leading to muscle weakness or loss of control on one side of the body. Hemiparesis can vary in severity, ranging from mild weakness to complete paralysis, depending on the extent and location of the brain injury.

The most commonly affected side of the body in hemiparesis is contralateral, meaning the weakness or paralysis occurs on the opposite side of the brain lesion. For example, if the stroke affects the left side of the brain, the right side of the body may experience hemiparesis.

This motor dysfunction can significantly impact a person's ability to perform daily activities, including walking, reaching, and grasping objects. Rehabilitation and physical therapy are essential components of stroke management, aiming to improve motor function, restore independence, and enhance quality of life for individuals with hemiparesis.
