In assessing a client with skin ulcers on the lower extremity, which findings indicate that the ulcers are likely to be of venous, rather than arterial, origin?
Absent pedal pulses and shiny skin.
Irregular ulcer shapes and severe edema.
Hairless lower extremities and cool feet.
Black ulcers and dependent rubor.
The Correct Answer is B
B. Severe edema is a common finding in venous insufficiency and is often present in the lower extremities. Venous hypertension leads to fluid leakage from capillaries, resulting in edema, which contributes to the development of venous ulcers. Venous ulcers typically have irregular shapes with irregular wound margins and may appear shallow or superficial.
A. Absent pedal pulses suggest arterial insufficiency, as reduced blood flow compromises peripheral circulation. Shiny skin, known as "thinning of the skin," is a characteristic finding in arterial insufficiency due to chronic ischemia and tissue hypoxia.
C. Hair loss on the lower extremities is a common finding in arterial insufficiency due to decreased blood flow to the hair follicles.
D. Black ulcers (gangrene) are indicative of tissue necrosis resulting from severe arterial insufficiency and lack of oxygen supply to the tissues. Dependent rubor refers to redness of the lower extremities when the legs are in a dependent position.

Correct Answer is ["A","B","D","E","F","G"]
Explanation
A. Patients with respiratory distress often prefer to sit upright or in a tripod position to ease breathing by allowing maximal lung expansion. Sitting upright helps relieve pressure on the diaphragm and allows better air exchange in the lungs.
B. Chest tightness is a common symptom of various respiratory conditions, such as asthma, chronic obstructive pulmonary disease (COPD), or pneumonia. It can result from bronchoconstriction, inflammation, or accumulation of mucus in the airways, leading to difficulty breathing.
D. An increased respiratory rate (tachypnea) may indicate respiratory distress or difficulty breathing. Tachypnea is a compensatory mechanism to increase oxygen intake or remove carbon dioxide from the body when lung function is compromised.
E. Restlessness can be a cue for a respiratory problem. Patients experiencing respiratory distress may exhibit restlessness due to hypoxia (low oxygen levels), discomfort, or anxiety related to difficulty breathing.
F. Dyspnea, or shortness of breath, is a significant cue for a respiratory problem. It is a common symptom of various respiratory conditions, including asthma, COPD, pneumonia, and pulmonary embolism. Dyspnea may range from mild to severe and can significantly impact the patient's quality of life and functional status.
G. A pulse oxygenation level of 85% indicates hypoxemia (low blood oxygen levels) and is a significant cue for a respiratory problem. Hypoxemia can result from various respiratory conditions or inadequate ventilation and may lead to tissue hypoxia and organ dysfunction if left untreated.
C. Medication compliance is not directly indicative of a respiratory problem. However, it may be relevant to managing respiratory conditions if the patient requires medications such as bronchodilators or corticosteroids to control symptoms or prevent exacerbations.
H. While an elevated heart rate (tachycardia) can be associated with respiratory distress, it is not specific to respiratory problems and may occur in response to other stressors or medical conditions.
I. Body mass index (BMI) is a measure of body fat based on height and weight and is not directly indicative of a respiratory problem. However, obesity is a risk factor for respiratory conditions such as obstructive sleep apnea and obesity hypoventilation syndrome.
Correct Answer is B
Explanation
B. Redness, tenderness, and drainage around the catheter site are classic signs of an exit site infection in peritoneal dialysis. Exit site infections are a common complication of peritoneal dialysis and can lead to more serious complications, such as peritonitis, if not promptly treated. Preventing exit site infections through proper catheter care and hygiene is essential in peritoneal dialysis management.
A. While outflow obstruction can occur in peritoneal dialysis, it typically presents with symptoms such as poor drainage of dialysate fluid, abdominal discomfort, and a decrease in dialysis efficiency. The described findings of redness, tenderness, and drainage around the catheter site are more indicative of a localized issue rather than outflow obstruction.
C. Atelectasis refers to the collapse of a part or the entire lung. While it can occur in hospitalized patients, especially those with underlying respiratory conditions, the described findings are not indicative of atelectasis. Atelectasis typically presents with symptoms such as dyspnea, cough, and decreased breath sounds on auscultation.
D. Peritonitis is a severe complication of peritoneal dialysis characterized by inflammation and infection of the peritoneal lining. While redness, tenderness, and drainage around the catheter site may precede peritonitis, the focus of concern in this scenario is primarily on preventing exit site infection, which, if left untreated, can progress to peritonitis.
