In assessing a client with ulcers on the lower extremity, which findings indicate that the ulcers are likely to be of venous, rather than arterial, origin?

Irregular ulcer shapes and severe edema.

Hairless lower extremities and cool feet.

Black ulcers and dependent rubor.

Absent pedal pulses and shiny skin.

Answer and Explanation

The Correct Answer is A

Choice A reason: Irregular ulcer shapes and severe edema are characteristic of venous ulcers, which are caused by impaired venous return and increased capillary pressure. Venous ulcers are usually located near the medial malleolus and have a shallow depth.

Choice B reason: Hairless lower extremities and cool feet are signs of arterial insufficiency, which reduces blood flow and oxygen delivery to the tissues. Arterial ulcers are usually located on the toes, heels, or lateral malleoli and have a deep, punched-out appearance.

Choice C reason: Black ulcers and dependent rubor are also signs of arterial insufficiency, indicating tissue necrosis and inflammation. Dependent rubor is a reddish-blue color of the lower extremity that occurs when the leg is lowered below the level of the heart.

Choice D reason: Absent pedal pulses and shiny skin are also signs of arterial insufficiency, indicating reduced blood flow and atrophy of the skin. The skin may also be dry, scaly, or cracked.

Correct Answer is B

Explanation

Choice A reason: The humoral immune response is mediated by B cells that produce antibodies against specific antigens. However, this response is not the main problem in AIDS, because B cells are not directly affected by the human immunodeficiency virus (HIV) that causes AIDS. Therefore, this choice is incorrect.

Choice B reason: The cellular immune response is mediated by T lymphocytes that activate other immune cells, such as macrophages, to destroy infected or abnormal cells. This response is the main problem in AIDS, because HIV infects and destroys CD4+ T cells, which are essential for coordinating the cellular immunity. As a result, the client becomes susceptible to opportunistic infections, such as Pneumocystis jiroveci pneumonia. Therefore, this choice is correct.

Choice C reason: Bone marrow suppression of white blood cells can cause immunodeficiency, but it is not the primary cause of AIDS. Bone marrow suppression can occur as a side effect of some drugs or treatments, such as chemotherapy or radiation therapy, but it is not directly caused by HIV. Therefore, this choice is incorrect.

Choice D reason: Exposure to multiple environmental infectious agents can challenge the immune system, but it does not necessarily cause it to fail. The immune system can adapt and respond to different pathogens, unless it is compromised by an underlying condition, such as AIDS. Therefore, this choice is incorrect.

A. Basic metabolic panel B. Echocardiogram C. CT scan of abdomen D. Blood cultures times 2 sets E. Chest X-ray F. Place on continuous cardiac monitor G. CBC H. 12 lead EKG

Correct Answer is ["F","H"]

Explanation

a) Basic metabolic panel: This is a blood test that measures the levels of electrolytes, glucose, calcium, and kidney function. It is not a priority order for this client because her glucose level is within the normal range and her symptoms are not indicative of electrolyte imbalance or kidney failure.

b) Echocardiogram: This is a test that uses sound waves to create images of the heart and its valves, chambers, and blood flow. It is not a priority order for this client because her chest discomfort may not be related to a cardiac problem and her SpO2 is normal, indicating adequate oxygenation.

c) CT scan of abdomen: This is a test that uses X-rays to create detailed pictures of the organs and structures in the abdomen. It is not a priority order for this client because her abdominal pain is not severe or acute and her nausea and poor appetite may be due to her illness or dialysis.

d) Blood cultures times 2 sets: This is a test that checks for the presence of bacteria or fungi in the blood. It is not a priority order for this client because she does not have signs of infection such as fever, chills, or leukocytosis.

e) Chest X-ray: This is a test that uses X-rays to create images of the lungs and chest wall. It is not a priority order for this client because she does not have respiratory symptoms such as cough, shortness of breath, or wheezes.

f) Place on continuous cardiac monitor: This is an order that requires the nurse to attach electrodes to the client's chest and monitor the heart rate and rhythm continuously. This is a priority order for this client because she has a history of CAD and HTN and reports chest discomfort and lightheadedness, which could indicate a possible myocardial infarction (heart attack) or arrhythmia (irregular heartbeat).

g) CBC: This is a blood test that measures the number and types of blood cells, such as red blood cells, white blood cells, and platelets. It is not a priority order for this client because she does not have signs of anemia, bleeding, or infection.

h) 12 lead EKG: This is a test that records the electrical activity of the heart from 12 different angles. It can detect abnormalities in the heart's rhythm, conduction, or damage. This is a priority order for this client because she has a history of CAD and HTN and reports chest discomfort and lightheadedness, which could indicate a possible myocardial infarction (heart attack) or arrhythmia (irregular heartbeat).
