49)  The physician has ordered Metoprolol 150 mg QID.  The dosage on hand is 100mg tablets. The recommended dose is 300mg/kg/day. How many tablets will the nurse administer to the patient?

38)  The nurse is discharging a client who was admitted for a pulmonary embolism. What “preventative” client teaching should the nurse do? (Select all that apply)

13)  The nurse is administering guaifenesin to a patient.  Which of the following guidelines are priority for the nurse to provide to the patient related to this medication? 

How do buffers work?

The following questions are based on the 15 molecules illustrated in the accompanying figure. Each molecule may be used once, more than once, or not at all.Which of the following molecules act as building blocks (monomers) of polypeptides?

As a protein is being made, the nonpolar (hydrophobic) amino acids tend to move toward the inside of the protein, away from the surrounding water. Part 1:What is this phenomenon called, and why does it occur?(Hint: Think about how nonpolar molecules behave in water.) Part 2:How does this movement of nonpolar amino acids affect the overall folding of the protein?Explain how this contributes to the tertiary structure, and how it might influence the secondary and quaternary levels of protein structure.

Proteins start as long chains of amino acids, but they fold into specific three-dimensional shapes that allow them to do their jobs in the cell. Explain how a protein folds into its final shape.In your answer, describe the role of: The sequence of amino acids (primary structure) Interactions between side chains (such as hydrogen bonds, ionic bonds, and hydrophobic interactions) How this leads to the secondary, tertiary, and possibly quaternary levels of protein structure.

A neutral solution

Provide a molecular formula that is consistent with the following mass spectral data.M+• at m/z = 167, relative height = 50.0%(M+1)+ • at m/z = 168, relative height = 4.4%
