When planning care for a client who is diagnosed with a large abdominal aortic aneurysm (AAA), the nurse should carefully monitor for which signs and symptoms?

Flank pain and profound hypotension.

Acute shortness of breath and chest pain.

Absent pedal pulses and darkened toes.

Tea-colored urine and decreased output.

Answer and Explanation

The Correct Answer is A

A) Flank pain and profound hypotension:

Correct. Flank pain, often described as a deep, constant, gnawing, or throbbing sensation in the abdomen or back, can be a sign of impending rupture or dissection of an abdominal aortic aneurysm (AAA). Profound hypotension may occur if the AAA ruptures, leading to massive internal bleeding and shock. Prompt recognition of these signs is crucial for early intervention and surgical repair to prevent catastrophic consequences.

B) Acute shortness of breath and chest pain:

Acute shortness of breath and chest pain are more indicative of cardiovascular or pulmonary conditions such as myocardial infarction, pulmonary embolism, or acute coronary syndrome rather than an abdominal aortic aneurysm. While aortic dissection can present with chest pain, it is typically described as severe, tearing, or ripping pain that radiates to the back, not as acute shortness of breath.

C) Absent pedal pulses and darkened toes:

Absent pedal pulses and darkened toes may indicate peripheral vascular disease or critical limb ischemia but are not specific signs of an abdominal aortic aneurysm. While AAA can lead to peripheral ischemia in advanced cases, it is not typically associated with acute changes in pedal pulses or toe discoloration.

D) Tea-colored urine and decreased output:

Tea-colored urine and decreased urine output may indicate acute kidney injury or rhabdomyolysis but are not specific signs of an abdominal aortic aneurysm. While a ruptured AAA can lead to renal ischemia and acute kidney injury due to hypoperfusion, these symptoms are not the primary manifestations of AAA

Correct Answer is A

Explanation

A. Provide pressure over the biopsy site:

Positioning the client on the right side after a liver biopsy is aimed at providing pressure over the biopsy site. This pressure helps in promoting hemostasis by compressing the blood vessels at the biopsy site, thus reducing the risk of bleeding or hematoma formation. The liver is located on the right side of the body, so positioning the client on the right side applies pressure directly over the liver, aiding in the prevention of bleeding complications.

B. Keep the client from aspirating:

Positioning the client on the right side after a liver biopsy is not primarily aimed at preventing aspiration. Aspiration precautions are typically implemented during procedures where there is a risk of regurgitation or vomiting, such as during anesthesia induction or recovery, rather than specifically after a liver biopsy.

C. Lessen the amount of post-procedure pain:

While positioning can play a role in managing post-procedure pain, the primary reason for positioning the client on the right side after a liver biopsy is to provide pressure over the biopsy site to promote hemostasis. Pain management strategies such as administering analgesics may be utilized to address any discomfort experienced by the client post-procedure.

D. Facilitate pulmonary expansion:

Positioning the client on the right side after a liver biopsy does not directly facilitate pulmonary expansion. Facilitating pulmonary expansion is typically achieved through interventions such as deep breathing exercises, incentive spirometry, and early ambulation rather than positioning alone.

A. Produce the sensation of Itching. B. Tighten airway and produce mucous. C. Causes formation of bradykinin. D. Serves as receptor for antigen.

Correct Answer is B

Explanation

Leukotrienes are inflammatory mediators derived from arachidonic acid metabolism, primarily produced by leukocytes (white blood cells) such as mast cells, eosinophils, and basophils. In the context of asthma, leukotrienes play a significant role in the pathophysiology of the disease by contributing to airway inflammation and bronchoconstriction. Here's a breakdown of their immune response:

A) Produce the sensation of itching:

Leukotrienes are not directly involved in producing the sensation of itching. Itching is often associated with histamine release rather than leukotrienes.

B) Tighten airway and produce mucous:

Correct. Leukotrienes are potent bronchoconstrictors that cause smooth muscle contraction in the airways, leading to narrowing (constriction) of the bronchioles. Additionally, they stimulate the secretion of mucus from goblet cells in the airway epithelium, contributing to airway obstruction and mucus production, which are characteristic features of asthma exacerbations.

C) Causes formation of bradykinin:

Bradykinin is a peptide mediator that is generated from the plasma protein kininogen and is involved in vasodilation, pain sensation, and inflammation. Leukotrienes are not directly responsible for the formation of bradykinin.

D) Serves as a receptor for antigen:

Leukotrienes do not serve as receptors for antigens. Instead, they are lipid mediators released in response to various stimuli, including allergens, infections, and irritants, and they act on specific receptors (e.g., leukotriene receptors) to exert their effects, such as bronchoconstriction and inflammation
