The top figure shows four signaling pathways, labeled 1 through 4. All pathways begin with the same receptor being triggered by the same signaling molecule. However, the secondary messengers that follow are ordered differently among the pathways. The bottom figure shows a relationship between the presence or absence of an activated protein X and the activity of protein W. Which signaling pathways are consistent with the data presented in the bottom figure? Select all that apply.

The figure shows a signaling pathway for epinephrine, a signaling molecule that can bind to an alpha-1 receptor. True or false? Once activated, calmodulin activates IP3.

Which statements accurately describe a hormone? Select all that apply.

Which statements accurately describe hydrophobic signaling molecules? Select all that apply.

Only three of the following statements are accurate. Which statement is inaccurate?

The figures show two signaling molecules, labeled 1 and 2. Which statement accurately contrasts the two molecules?

True or false? A signaling molecule can bind to a receptor on either the outside or inside of a cell.

The figure shows a signaling pathway for epinephrine, a signaling molecule that can bind to an alpha-1 receptor. Which molecule directly activates protein kinase C?

On 5/12/xx, the evening nurse is preparing to administer the 1800 dose of nafcillin 750 mg IM to the patient. A day nurse had opened and reconstituted a 2 g vial of nafcillin and stored the mixed vial in the refrigerator. The day nurse had attached the following label to the nafcillin vial: 6.6 mL sterile water for injection added0600 5/10/xx250 mg/mLRefrigerateBeyond-use-date: 0600 5/13/xxR.G., RN After checking the beyond-use-date, the evening nurse calculated the ordered dose and administered ____ mL to the patient.
