The nurse is taking care of a patient who is newly diagnosed with heart disease. The patient is asking questions about how blood flows through the heart.
The nurse responds, when the left ventricle contracts, it pushes blood through a valve to the:
Pulmonary artery.
Aorta.
Inferior vena cava.
Pulmonary vein.
The Correct Answer is B
Choice A rationale:
The pulmonary artery carries deoxygenated blood from the right ventricle to the lungs, not from the left ventricle.
Choice B rationale:
The aorta is the main and largest artery in the human body, originating from the left ventricle of the heart and extending down to the abdomen.
Choice C rationale:
The inferior vena cava carries deoxygenated blood from the lower half of the body back to the right atrium of the heart, not from the left ventricle.
Choice D rationale:
The pulmonary vein carries oxygenated blood from the lungs to the left atrium, not from the left ventricle.

Correct Answer is ["1140"]
Explanation
To calculate the total intake, we need to convert all measurements to mL. 1 oz is approximately 30 mL, 1 cup is approximately 240 mL. So, 4 oz of soda is 120 mL, 12 oz of water is 360 mL, 1 cup of gelatin is 240 mL, and 1/2 cup of broth is 120 mL. Adding these to the 300 mL of IV fluid gives us 1140 mL. However, the toast is not a liquid and cannot be measured in mL, so it is not included in the total intake.
Correct Answer is A
Explanation
Choice A rationale:
Encouraging the client to take slow, deep breaths is a holistic approach that can help manage pain by promoting relaxation and reducing stress.
Choice B rationale:
Checking the client’s oxygen saturation level is a physiological assessment, not a holistic approach.
Choice C rationale:
Obtaining blood work is a medical intervention, not a holistic approach.
Choice D rationale:
Requesting a prescription for an analgesic is a pharmacological intervention, not a holistic approach.
