A nurse is caring for a client in the Medical-Surgical Unit. Nurses Notes: Day 1:  Client has a 10.2 cm (4 in) by 10.2 cm (4 in) raised, reddened abscess on left thigh. The client reports that the area is warm and painful. Vital Signs: Temp – 39.6 C (103.3)F; BP – 118/56 mm Hg; HR – 106/min; RR – 22/min; O2 Sat 96% (RA) Diagnostic Results Day 2: CBC: WBC 45,000/mm3 (5000 to 10,000/mm3) Wound Culture and Sensitivity:  sample taken from left thigh abscess POSITIVE for methicillin-resistant Staphylococcus aureus (MRSA)  ** Please designate whether the intervention are: ANTICIPATED (2 of 2 needed); CONTRAINDICATED (2 of 2 needed); or NONESSENTIAL (1 of 1 needed).

A nurse is caring for a client who has Addison’s disease and is at risk for Addison crisis. Which of the following actions should the nurse take?

A nurse is preparing a continuous insulin infusion for a client with diabetic ketoacidosis and a blood glucose level of 800 mg/dl.  Which solution is the most appropriate at the beginning of therapy?

This virus’ capsid symmetry is ___.

Potato virus’ capsid symmetry is ____.

Explain how a mutation could decrease the virulence of the virus.  Recall this mutation is in the glycoprotein that mediates membrane fusion.  Answer this question by addressing the prompts A-D below. Which of the viruses is the least virulent?   Provide evidence from the end-point dilution assay to support your answer. (one sentence max) Which step(s) of the infection cycle is affected by this protein. (one sentence max) What is the role of this protein in membrane fusion (you must thoroughly describe the process of membrane fusion and the role of the glycoprotein in the process). (5 sentences max) How would this specific mutation negatively affect membrane fusion. (3 sentences max)

Use this prompt to answer questions 12-19. You discover a new virus that causes ulcers in the mouth and is transmitted through contact with infected saliva.  You name the virus Salivary Emission Ulcervirus, SEU for short.  SEU’s genome is single stranded DNA.  You are able to get an image using electron microscopy (left) and build a model of the virus (right).  After years of work, you find that SUE attaches to host cells using AB-1 as an attachment factor and YZ-2 as a receptor.  You use this information to better understand the tissue tropism of the virus.  You design an experiment to test multiple cell lines and determine if they can be infected by SEU.  Your results are below.

Based on the Baltimore System, SEU is a Class ___ virus.

In order for SEU to successfully infect a cell it must enter the cell via , triggered by the attachment of to the host’s proteins.

The viral genome can be packaged using… (choose all that apply).
