Information for Questions 15-16 This figure shows the results of a two-dimensional gel that was run to separate the proteins found in a snake toxin. Locate the prominent dark spot in the upper right-hand quadrant on the two-dimensional gel and answer the following questions.  Image Source: Hatakeyama, D. M., de Morais-Zani, K., Serino-Silva, C., Grego, K. F., Sant’Anna, S. S., Fernandes, W., Aniz, P. A. E. A., Torquato, R. J. S., Tanaka, A. S., Sanz, L., Calvete, J. J., & Tanaka-Azevedo, A. M. (2018). Examination of biochemical and biological activities of Bothrops jararaca (Serpentes: Viperidae; Wied-Neuwied 1824) snake venom after up to 54 years of storage. Toxicon (141), 34–42. Image Description  A two-dimensional Electrophoresis (2-DE) gel showing the separation of proteins. The x-axis represents the pH range from 3 to 10, and the y-axis represents molecular weight from 15 kDa to 250 kDa. Multiple protein spots are visible, indicating their isoelectric points and molecular weights. The label A marks a significant area of interest on the gel. The gradient shading reflects the concentration of proteins, with darker spots representing higher protein abundance.

An intubated term infant with severe meconium aspiration syndrome has persistent oxygen requirements despite appropriate lung expansion and ventilation. Why might surfactant improve respiratory function?

What is the effect of stimulating beta- receptors in the heart?

BONUS: Provide the universal number of the tooth in this picture. Note: This question will be manually graded once the assessment closes. Partial credit will not be awarded. 

A preterm infant born after maternal fever and prolonged rupture of membranes develops early respiratory distress. The chest radiograph shows low lung volumes, diffuse granular opacities, and air bronchograms. What is the most appropriate approach?

Drugs and their metabolites can be eliminated through pathways other than renal excretion. Which process involves the excretion of a drug through the biliary system into the gastrointestinal tract, followed by its reabsorption back into systemic circulation?

A spontaneously breathing preterm infant receiving CPAP develops increasing grunting and oxygen requirements. The interface is correctly positioned and delivering the prescribed pressure. Chest radiography shows low lung volumes, and perfusion remains adequate. What adjustment best addresses the underlying physiologic problem?

Which of the following drugs should be limited in patients taking Propranolol (Inderal)?
