The bones of your arms are called humerus, while your forearms are composed of two bones, the radius and ulna. The bones of your fingers are called metacarpals and each one of those small bones are called phalanges.

The bones of your shoulders are composed of the clavicle, the bony part seen just right under the neck. Part of the shoulder area is the scapula, which is located at the back part of the body attached to the upper part of the ribs. They are the triangle-shaped bones you feel when you cross your arms at the back. 

The bones of your thighs are called femur, they are the largest bones in your body. While the bones of your legs are called tibia and fibula. The bones of your toes are called tarsals and each are composed of smaller bones called metatarsals. Your heels also have bones and they are called calcaneus.

The bones of your pelvis are called Coxal bones as a whole but they are composed of the illium (biggest part of your hips); the pubic bone, located along the reproductive organ; the sacrum and coccyx all located at the base of the spine.

Aneli [31]
There are choices for this question namely:

Ativan 1 mg orally 
<span>Nitroglycerin SL </span>
<span>Serum electrolytes </span>
<span>Chest x-ray
</span>
The correct answer is "Nitroglycerin SL". The SL means sublingually. The physician will still order Nitroglycerin to be taken sublingually whenever there is chest pain. The patient's medication may have been expired being stored for 12 months now. Ativan or Lorazepam will not be given as this is a sedative and there is no indication for sedatives.

Serum electrolytes and chest xray will not be requested as these diagnostic examinations are not usually done in patients with stable angina.
