Answer:
In studying the origin of the universe, one of the primary unanswered questions is <u>what came before the big bang.</u>
Explanation:
The big bang theory can be described as a theory which scientists have proposed to explain how the universe came into existence. This theory predicts how the extremely hot temperatures and dense atmosphere might have given rise to the stars and the galaxies.
Scientists have no idea what happened before the big bang theory. Some scientists predict that there might be another universe which collapsed before the big bang theory. While other scientists claim that there was nothing before the big bang.

The question is incorrect. The correct question is as follows:
The nurse is orienting a new RN in the care of a patient with respiratory distress due to emphysema. The patient is being treated with O2 via a Venturi mask with 35% oxygen. Which statement by the new RN indicates that teaching has been effective, when the nurse questions the new RN about the use of the Venturi mask?
a. "A nasal cannula will dry the mucous membranes and cause an increased risk of infection."
b. "Her alveoli cannot absorb higher levels of O2 because of the emphysema."
c. "Her alveoli have been damaged and may rupture with higher doses of O2."
d. "Her respiratory center requires low O2 concentration to stimulate breathing."
Answer:
Her respiratory center requires low O2 concentration to stimulate breathing."
Explanation:
COPD ( Chronic obstructive pulmonary disease) may be defined as the combination of the different lung disease that might create problem in the respiration process.
The venturi mask is used in the medical condition to provide the proper amount of oxygen to the patient. In emphysema the individual suffered from the hypoxemia means low oxygen level in the body. The low oxygen is required to the patient and high oxygen level will disturb the normal process of breathing.
Thus, the correct answer is option (d).
