Answer:
The radiographer shall keep the patient in dorsal recumbent position with feet elevated.
Explanation:
Dorsal recumbent position is the one in which the patient lies on back with knees and thighs both flexed. the patient experiencing syncope may have a fall in blood pressure because increased diameter of blood vessels and decreased heart rate. A deficiency of oxygen supply to the brain causes syncope and fainting. Hence, placing the patient in dorso recumbent position with feet elevated improves blood flow to the brain.
Answer:
Intrinsic conduction system of the heart consists of the passage of the electrical impulse from the atrial node to the purkinje fiber system, to produce ventricular contraction.
Explanation:
The heart's electrical conduction system allows the heart to fulfill its blood-pumping functions through the alternating movements of contraction and relaxation of its musculature.
- The nerve impulse begins in the sinoatrial node (SA), located at the top of the right atrium. This produces the atrial contraction to pass the blood from the atria to the ventricles.
- From the SA, the impulse travels to the atrial-ventricular node (AV), located in the interventricular septum.
- In AV, the impulse is briefly delayed and then transmitted to the His bundle (HB), until the HB splits into a right and a left branch. The left branch is divided into three fascicles: anterior, middle and posterior.
- Finally, from each branch and its fascicles originate the Purkinje fibers, which are introduced into the heart muscle and produce - when the nerve impulse arrives - the contraction of both ventricles, and the exit of blood from their cavities.
This series of steps is responsible for the heart being able to pump blood throughout the body.

Answer: B. 41°F (5°C) or below
Explanation:
Time and tempurature controlled for safety (TCS) is the term used to identify food that requires specific time and temperature control for safety because some are particularly favorable to develop bacterial growth. Dairy products are part of the TCS foods, and since it´s cold food, they should be received, stored, and served at a temperature of 41°F (5°C) or lower.
