A nurse is assessing a client who has peripheral venous disease. Which of the following findings should the nurse recognize as a manifestation of venous disease?
Swollen and enlarged veins.
Loss of pigmentation over the shin area.
Shiny appearance to the lower extremities.
Diminished hair growth on the lower extremities.
The Correct Answer is A
Choice A Reason:
Swollen and enlarged veins, also known as varicose veins, are a common manifestation of peripheral venous disease (PVD). This condition occurs when the valves in the veins become weak or damaged, leading to blood pooling and increased pressure within the veins. This results in the veins becoming enlarged, twisted, and visible under the skin1. Varicose veins can cause discomfort, pain, and a heavy feeling in the legs. They are often exacerbated by prolonged standing or sitting and can be a cosmetic concern as well.
Choice B Reason:
Loss of pigmentation over the shin area is not typically associated with peripheral venous disease. This symptom is more commonly seen in conditions such as chronic venous insufficiency (CVI), where prolonged venous hypertension leads to skin changes, including hyperpigmentation and lipodermatosclerosis. However, it is not a primary manifestation of PVD itself.
Choice C Reason:
A shiny appearance to the lower extremities is more commonly associated with peripheral arterial disease (PAD) rather than peripheral venous disease. In PAD, reduced blood flow to the extremities can cause the skin to become thin, shiny, and hairless. This is due to the lack of oxygen and nutrients reaching the skin and underlying tissues. In contrast, PVD primarily affects the veins and does not typically cause these skin changes.
Choice D Reason:
Diminished hair growth on the lower extremities is another symptom more commonly associated with peripheral arterial disease (PAD). In PAD, the reduced blood flow to the extremities can lead to hair loss, as the hair follicles do not receive adequate oxygen and nutrients. Peripheral venous disease, on the other hand, does not usually cause hair loss. Instead, it is characterized by symptoms related to venous insufficiency, such as varicose veins, swelling, and skin changes.

Correct Answer is ["A","B","D"]
Explanation
Choice A reason:
Heart murmur is a common manifestation of valvular dysfunction. It occurs when there is turbulent blood flow across a damaged or abnormal heart valve. This can be due to stenosis (narrowing of the valve) or regurgitation (leakage of the valve). The murmur’s characteristics, such as timing, location, and intensity, can help in diagnosing the specific type of valvular disease. For example, a systolic murmur might indicate aortic stenosis or mitral regurgitation, while a diastolic murmur could suggest aortic regurgitation or mitral stenosis.
Choice B reason:
Chest pain is another symptom that can be associated with valvular dysfunction. This pain can result from increased workload on the heart due to inefficient blood flow through the valves. Conditions like aortic stenosis can lead to angina (chest pain) because the heart muscle may not receive enough oxygenated blood. This symptom is particularly concerning and warrants immediate medical attention to prevent complications such as myocardial infarction.
Choice C reason:
Varicose veins are not typically associated with valvular dysfunction in the heart. They are more related to issues with the veins in the legs, where the valves that prevent backflow of blood become weakened or damaged. This condition is generally referred to as chronic venous insufficiency and is not directly linked to the heart’s valvular problems.
Choice D reason:
Palpitations, or the sensation of irregular or rapid heartbeats, are common in clients with valvular dysfunction. These can occur due to arrhythmias, which are often seen in conditions like mitral valve prolapse or aortic regurgitation. The irregular heartbeats can be a result of the heart trying to compensate for the inefficient blood flow caused by the faulty valve.
Choice E reason:
Abdominal pain is not a typical manifestation of valvular dysfunction. While severe heart conditions can sometimes lead to generalized symptoms, abdominal pain is more commonly associated with gastrointestinal issues rather than heart valve problems. Therefore, it is not a primary symptom to anticipate in clients with valvular dysfunction.
Correct Answer is A
Explanation
Choice A Reason:
The adrenal glands play a crucial role in responding to low blood glucose levels by releasing epinephrine (adrenaline) and norepinephrine. These hormones help to increase blood glucose levels by stimulating glycogenolysis (the breakdown of glycogen to glucose) and gluconeogenesis (the production of glucose from non-carbohydrate sources) in the liver. This response is part of the body’s fight-or-flight mechanism, which ensures that sufficient glucose is available for immediate energy needs.
Choice B Reason:
The liver does not release glucagon; rather, it responds to glucagon, which is released by the pancreas. Glucagon stimulates the liver to convert stored glycogen into glucose (glycogenolysis) and to produce glucose from non-carbohydrate sources (gluconeogenesis). This process helps to raise blood glucose levels when they are low.
Choice C Reason:
Glycogenesis is the process of converting glucose into glycogen for storage, and it occurs primarily in the liver and muscle cells, not in the pancreas. The pancreas releases insulin to promote glycogenesis when blood glucose levels are high, but it does not perform glycogenesis itself.
Choice D Reason:
The brain primarily uses glucose for energy and does not switch to using protein unless glucose levels are extremely low and prolonged. In such cases, the brain can use ketone bodies derived from fat as an alternative energy source. Protein is not a primary energy source for the brain under normal conditions.
