The nurse is performing an integumentary system assessment of a patient who has smoked for the last 40 years. The patient has clubbing of the fingernails. What does this finding indicate to the nurse?
The patient has asthma.
The patient has cardiovascular disease.
The patient has emphysema.
The patient has chronic hypoxemia.
The Correct Answer is D
A) The patient has asthma: While asthma can lead to respiratory symptoms and issues, it is not typically associated with clubbing of the fingernails. Asthma primarily affects airway constriction and inflammation, rather than causing the long-term changes in nail morphology seen with clubbing.
B) The patient has cardiovascular disease: Although some cardiovascular conditions can lead to clubbing, it is more commonly associated with chronic lung diseases. Cardiovascular disease might cause other signs or symptoms, but clubbing alone is not a definitive indicator of this condition.
C) The patient has emphysema: Emphysema, a type of chronic obstructive pulmonary disease (COPD), is characterized by the destruction of lung tissue and impaired airflow. While it can contribute to hypoxemia, clubbing is not a common finding specifically associated with emphysema.
D) The patient has chronic hypoxemia: Clubbing of the fingernails is a classic sign of chronic hypoxemia, often resulting from long-term respiratory conditions like COPD, interstitial lung disease, or lung cancer. It indicates a prolonged lack of oxygen in the blood, leading to changes in the nail bed and digit shape. Given the patient's long smoking history, chronic hypoxemia is the most likely explanation for this finding.

Correct Answer is A
Explanation
A) Idiopathic neuropathy has no known cause: This statement is accurate, as idiopathic neuropathy refers to nerve damage for which no specific cause can be identified despite thorough investigation. The term "idiopathic" literally means "of unknown origin," indicating that the underlying mechanism remains unclear.
B) Idiopathic neuropathy is hereditary in nature: While some neuropathies can be hereditary, idiopathic neuropathy itself is not classified as hereditary since it lacks a defined genetic cause. Hereditary neuropathies are specific types that have a genetic basis.
C) Idiopathic neuropathy is caused by nutritional deficits: Nutritional deficits can lead to various types of neuropathy, but idiopathic neuropathy specifically is characterized by the absence of a known cause. Therefore, attributing it to nutritional deficits would be incorrect.
D) Idiopathic neuropathy is caused by disease or illness: While certain diseases can cause neuropathy, the key characteristic of idiopathic neuropathy is that no specific disease or illness has been identified as the cause. This differentiates it from other neuropathies that are secondary to identifiable conditions.
Correct Answer is D
Explanation
A) Changes in peripheral vision in response to light: While peripheral vision is important in a comprehensive eye assessment, it is not specifically evaluated through the PERRLA acronym. PERRLA focuses on how the pupils respond to light and accommodation, not on peripheral vision changes.
B) Involuntary blinking in the presence of bright light: Involuntary blinking is part of a reflex action known as the blink reflex, which helps protect the eyes from bright lights and foreign objects. However, this response is not what the "A" in PERRLA refers to, which is more specifically about pupillary reactions to focus.
C) Pupillary dilation when looking at a near object: When focusing on a near object, the pupils actually constrict rather than dilate. This process, known as accommodation, is important for clear vision at close distances but does not pertain to the dilation of pupils.
D) Pupillary constriction when looking at a near object: The "A" in PERRLA stands for accommodation, which specifically refers to the pupils constricting when a person looks at a nearby object. This reaction helps the eyes focus properly and is a normal finding in a healthy neurological assessment. Thus, option D accurately describes the "A" in the PERRLA assessment.
