A patient suddenly develops signs and symptoms that resemble “hemiballismus” (expression of involuntary movement), but only on one side of the body. Knowing that such “hyperkinetic” movement disorders have something to do with the basal ganglia and that you suspect the patient had a stroke, which cerebral artery should you consider as possibly being involved in this stroke?

a lenticulostriate branch of the middle cerebral artery
an amygdalo-hippocampal branch of the anterior choroidal artery
sulcal branch of the anterior spinal artery
a circumferential branch of the basilar artery
a paramedian perforating branch of the posterior cerebral artery

Answers

Answer 1

Answer:

A. a lenticulostriate branch of the middle cerebral artery

Explanation:

Hemiballismus is usually caused by a stroke that affects a small area just below the basal ganglia called the subthalamic nucleus.

The majority of the subthalamic nucleus receives its blood supply from the posteromedial branches of the posterior cerebral artery. The lateral portions of the subthalamic nucleus can receive vascular supply from the lenticulostriate arteries of the middle cerebral artery.

The reason why choice A is preferred over choice E (a paramedian perforating branch of the posterior cerebral artery) because choice A supplies lateral portions of the subthalamic nucleus.

Convert 8 mL to gtt

Answers

The conversion of mL to gtt depends on the specific liquid you are measuring. Please provide more information so I can help you convert 8 mL to gtt.

When 8ml is converted into 120 gtt.

The drop factor, which refers to the number of drops per milliliter, determines how much liquid is measured in milliliters (mL) and converted to drops (gtt). The type of liquid or solution being used, its viscosity, and the size of the dropper are just a few examples of variables that can affect drop factor.

Drop factor is often stated in medical contexts for specific devices, such as IV (intravenous) administration systems or special dropper bottles. Health care facilities often use drop factors such as 10 gtt/mL, 15 gtt/mL, and 20 gtt/mL.

To convert mL to GTT, multiply the milliliter volume by the drop factor. For example, the conversion would be as follows if you had 8 mL of liquid and the drop factor was 15 gtt/mL:

8 mL * 15 gtt/mL = 120 gtt
