You are working as a nurse in the emergency department and are providing care for a patient with pneumonia. What signs and symptoms would indicate hypoxia in this patient? Select all that apply. 1. Central cyanosis 2. Cough 3. Use of accessory muscles 4. Change in mental status 5. Fever 6. Tachypnea
1, 3, 4, 6. Hypoxia means low levels of oxygen in the blood. This answer is looking for symptoms of hypoxia. Central cyanosis is a blue discoloration around the mouth or oral mucosa. This indicates a lack of oxygen and needs to be addressed immediately because it means that essential organs are not getting oxygen. The use of accessory muscles indicates that breathing is not easy and the patient is not getting enough oxygen. Change in mental status is an early sign of hypoxia. Tachypnea indicates air-hunger and means the patient is working hard to get more oxygen. Cough and fever are symptoms of pneumonia but do not indicate hypoxia.
What is the complimentary DNA sequence for the DNA strand 5'GATCCAGC3'?
3'CTAGGTCG5' To determine the complimentary strand you have to know that A and T are complimentary to each other and G and C are complimentary to each other. Based on the strand given in the question you switch out the base pairs for their complimentary alternative to determine the new sequence.
18 - 7x = 2x + 9
18 - 7x = 2x + 9 18 = 9x + 9 (add 7x to both sides) 9 = 9x (subtract 9 from each side to isolate x on one side of the equation) x = 1 (divide both sides by 9 to solve for x)
