A client is in the critical care unit. She is currently receiving oxygen at 2 L/min by nasal cannula; nitroglycerin paste 1 inch to the chest wall, and  Metaprolol 25 mg orally every 12 hours. The monitor shows that the client has started having PVCs. Over the course of the next several hours, the premature ventricular contractions (PVC)  increase in frequency to more than 15 per minute, with occasional burst of multifocal bigeminal PVCs. The client’s vital signs are heart rate, 84 beats/min, sinus rhythm, with described PVCs; blood pressure, 124/68 mm Hg; respirations, 20 breaths/min; SpO2, 90%. Laboratory values are blood pH, 7.44; potassium, 4.6 mEq/L; and magnesium 0.9 mEq/L. Which of the following, if ordered, would be inappropriate for this client?

Which of the following is embedded within the Rough ER?

Structural polysaccharide found in the exoskeleton of invertebrates.  It is also fund in the cell wall of fungi.

Dynein is a plus-end directed microtubule motor protein.

The monomers for intermediate filaments, microtubules and microfilaments can all bind to and hydrolyze ATP/GTP.

If the G-actin concentration is greater than the critical concentration, an actin filament will grow.

Which clinical manifestations are indicative of left ventricular failure? (Select all that apply)

The GTP binding site of yeast beta-tubulin was mutated, resulting in an increase in the rate of GTP hydrolysis for the mutant as compared to normal beta-tubulin (in other words, there is more GDP bound tubulin than GTP bound).  Predict the effects of this mutation on dynamic instability (make sure to use words like “catastrophe” and “rescue” in your answer).

This type of reaction joins monomers by removing a water molecule.
