Question

A. Gram-positive bacteria have more peptidoglycan in their cell walls.

B. Gram-positive bacteria have fimbriae but gram-negative bacteria do not.

C. Gram-positive bacteria are spiral-shaped, and gram-negative bacteria are either rod-shaped or spherical.

F. Gram positive are positively charged and gram negative are negatively charges

An unknown bacterial species was found in the blood of a septic patient and it contains LPS in its cell membrane. This observation indicates that

A. the infection should be relatively easy to control with common antibiotics, because the pathogen is a gram-positive species.

B. the infection should be relatively easy to control with common antibiotics, because the pathogen is a gram-negative species.

C. the infection may be quite threatening and difficult to control, because the pathogen is a gram-positive species

D. the infection may be quite life threatening and difficult to control, because the pathogen is a gram-negative species.

A patient comes into your office complaining of a shortness of breath, fatigue, and severe edema. You refer the patient out for an echocardiography and the results come back that the patient has an ejection fraction is 60% and an E/A ratio of 0.5. What is your diagnosis of this patient (do they have systolic or diastolic dysfunction)?

A. Systolic dysfunction

B. Diastolic dysfunction

C. Neither, the patient is fine

D. Both, the patient is suffering from both systolic and diastolic dysfunction

Answer 1

1) Gram positive bacteria have more complex peptidoglycan in their cell is correct option

2) The infection maybe quite life threatening and difficult to control, because the pathogen is a gram negative species is correct option

3) NF kappa B is correct answer

4) Mosses and fern required water to swim flagellated sperm towards option B is correct

5) Diastolic dysfunctional option is correct
