ASSESSING THE PERIPHERAL VASCULAR SYSTEM. Prior to performing the procedure, introduce self and verify the client’s identity using agency protocol. Explain to the client what you are going to do, why it is necessary, and how he or she can participate. Discuss how the results will be used in planning further care or treatments.

 

2. Perform hand hygiene and observe other appropriate infection prevention procedures.

 

3. Provide for client privacy.

 

4. Inquire if the client has any of the following: past history of heart disorders, varicosities, arterial disease, and hypertension; lifestyle habits such as exercise patterns, activity patterns and tolerance, smoking, and use of alcohol.

 

 

5. Palpate the peripheral pulses on both sides of the client’s body individually, simultaneously (except the carotid pulse), and systematically to determine the symmetry of pulse volume. If you have difficulty palpating some of the peripheral pulses, use a Doppler ultrasound probe.

 

6.  Inspect the peripheral veins in the arms and legs for the presence and/or appearance of superficial veins when limbs are dependent and when limbs are elevated.

 

7. Assess the peripheral leg veins for signs of phlebitis. Inspect the calves for redness and swelling over vein sites.

• Palpate the calves for firmness or tension of the muscles, the presence of edema over the dorsum of the foot, and areas of localized warmth. Push the calves from side to side to test for tenderness.
• Firmly dorsiflex the client’s foot while supporting the entire leg in extension (Homans’ test), or have the person stand or walk.

 

8. Inspect the skin of the hands and feet for color, temperature, edema, and skin changes.

 

9. Assess the adequacy of arterial flow if arterial insufficiency is suspected.

• Press at least one nail on each hand and foot between your thumb and index finger sufficiently to cause blanching (about5 seconds).
• Release the pressure, and observe how quickly normal color returns (less than 2 seconds).
• Inspect the fingernails for changes indicative of circulatory impairment. See the section on assessment of nails earlier in this chapter.
• See also peripheral pulse assessment earlier

 

10. Document findings in the client record using printed or electronic forms or checklists supplemented by narrative notes when appropriate

Describe the pathophysiologic changes associated with bacterial meningitis in regard to each of the following : Ms. J, a 19-year-old college student, has been living in a dormitory on campus. She began experiencing severe headaches, neck pain and nuchal rigidity, along with irritability and nausea.

She noticed that when lying with her hips flexed, she found it very hard to stretch out her legs. Within a day, her condition deteriorated.

She experienced a tonic-clonic seizure while trying to get some fluid-replacement drinks from the cafeteria. EMS was called, and she was quickly admitted to the hospital. Tests revealed increased intracranial pressure, fever, and leukocytosis. Bacterial meningitis was suspected, and a lumbar puncture was scheduled. Her parents are traveling to be with her.

Case Study 2 Questions

1. Describe the pathophysiologic changes associated with bacterial meningitis in regard to each of the following manifestations that the patient exhibits: severe headaches, neck pain, nuchal rigidity, limited hip motion, seizures, and increased intracranial pressure.
2. Which of these manifestations is (are) most significant in the diagnosis of bacterial meningitis? Why are there no focal signs present? What signs indicating increased intracranial pressure might you expect?
3. What are the causes of meningitis? Which microbe is most likely to be the cause in this case?
4. Discuss the transmission of bacterial meningitis and recommendations to protect other students and family. Think about her living situation and exposures and include these factors in your answer.
6. After the lumbar puncture is completed and the CSF is analyzed, what do you expect to see in the lab report?
7. Discuss the treatments available to help return this patient to a more homeostatic state. What is her prognosis? What are some possible long-term complications?

Case Study 1

Mr. Q, age 64 years, developed a severe headache several hours ago that has not responded to acetaminophen, rest, cold packs, or NSAIDS. Now his speech is slurred, and his right arm and the right side of his face feel numb.

His wife reports that he “looks funny,” and that his face is “half dead.” He is very anxious and is transported to the hospital. Mr. Q has a history of smoking and arteriosclerosis, and there is family history of CVA and diabetes.

Assessment at the hospital indicates weakness on the right side, including facial asymmetry and a blood pressure of 220/110 Hg mm. A CT scan shows damaged tissue on the left side of the brain, and an angiogram indicates narrowing of the carotid arteries and middle cerebral arteries, with occlusion of the left middle cerebral artery. It is determined that Mr. Q is likely experiencing a CVA.

Case Study 1 Questions

1. Describe the three causes of CVAs and the characteristic onset signs and symptoms associated with each. What do you think is most likely in this case?
3. What predisposing factors for CVA can you identify for Mr. Q?
5. Describe the pathological changes that caused the following initial signs and symptoms: slurred speech, right-sided weakness, facial asymmetry, hypertension.
7. Thinking about these pathological changes, discuss two interventions that can help correct the pathology and return Mr. Q to a more homeostatic state.

After admission and discussion about Mr. Q’s history, you find out that he has had several brief episodes of right-sided tingling and speech troubles over the last few months. T

he symptoms resolved on their own, although he is not sure how long it took. He never sought care for these, but his wife does report being concerned about them. She states that she was worried her husband might have a brain tumor but never thought about a “stroke.”

 

1. Based on his description of symptoms, what do you think Mr. Q was experiencing when he had the intermittent episodes of symptoms before today?
2. How do these episodes differ from a CVA? Discuss the cause of each type of episode and the expected signs and symptoms of each.
3. If Mr. Q had a brain tumor, would his signs and symptoms have been different? Choose one location of a brain tumor and describe the focal and general signs you would expect as the tumor grows.
4. Mr. and Mrs. Q want to know how long it is going to take for him to get back to normal. How will you answer them? What factors might influence the degree of functional recovery he can expect to achieve?

Which statement is true of direct proportionality?

 

 

		If the x variable increases by 25%, then the y variable increases by 50%.
		The graph of a directly proportional relationship is a straight line.
		The graph of a directly proportional relationship may cross the y axis at any value.
		The slope of a directly proportional relationship can never be less than one.
