74. When teaching a patient about antiviral therapy for recurrent HSV-1, which statement demonstrates understanding of prophylactic therapy?

5. While performing an assessment, the nurse hears crackles in the patient’s lung fields. The nurse also learns that the patient is sleeping on three pillows to help with the difficulty breathing during the night. Which condition will the nurse most likely observe written in the patient’s medical record?

13. Which condition would the nurse report has developed in the patient with a respiratory rate of 25 breaths/min?

38. The nurse auscultates normal soft low-pitched breath sounds throughout the posterior and lateral thoraxes. What is the name of this sound?

24. Which resource would the nurse consider accurate for assessing the pain of a patient who rates the pain as a 6 on a scale of 0 to 10, but the patient’s wife says that the patient cannot be in that much pain because the patient has been sleeping for 30 minutes?

25. A nurse teaches the patient about the gate control theory. Which statement made by a patient reflects a correct understanding about the relationship between the gate control theory of pain and the use of meditation to relieve pain?

23. Which step of the nursing process is the nurse using when teaching a patient how to use patient-controlled analgesia (PCA)?

6. What is the correct sequence of blood flow through the heart chambers?

35. The nurse is listening to the client’s heart at the right sternal border (RSB) at the second intercostal space (ICS). Which area is being auscultated?

The figure below illustrates A) normal development of a sea urchin embryo, B) development of the isolated animal hemisphere and C) development of the animal hemisphere + micromeres. Note that sea urchins are triploblasts and form all three germ layers (blue = ectoderm, yellow = endoderm, red = mesoderm). While the animal half of an early sea urchin embryo does not gastrulate, and does not form a normal larva when isolated, the micromeres can rescue gastrulation and development of the animal half; the resulting larva does have mesoderm, but is lacking endoderm. See the picture below. You find that the Delta protein is expressed in the micromeres of an intact sea urchin embryo.  You know that Delta is a signaling molecule that activates the Notch receptor on adjacent cells and you hypothesize that Delta from the micromeres is interacting with Notch on the veg2 cells to specify the secondary mesodermal (from veg2) fate.  B) Describe a ‘loose it’ experiment that would show that the interaction of Delta and Notch on adjacent cells is necessary for the rescuing ability of the micromeres.  Note that you cannot make genetic mutants in sea urchins, so don’t propose that!  Include a result that would be consistent with your hypothesis and one that is inconsistent with your hypothesis.
