A nurse is caring for a 58-year-old male client in an outpatient clinic.

Select the 3 possible conditions that could have the clinical manifestations of clubbed nails for this client.

Pneumonia

Lung cancer

Chronic obstructive pulmonary disease (COPD)

Chronic bronchitis

Flu

Answer and Explanation

Correct Answer : B,C,D

Choice A rationale: Pneumonia is an acute infection of the lung parenchyma, often causing fever, cough, and infiltrates on chest imaging. Clubbing usually develops over weeks to months, associated with chronic hypoxia or inflammation, which is uncommon in acute pneumonia. Therefore, clubbing is not typically a manifestation of pneumonia. The nail changes require persistent hypoxemia or chronic pulmonary pathology, which acute pneumonia generally does not produce.

Choice B rationale: Lung cancer can cause digital clubbing due to tumor-induced secretion of growth factors such as vascular endothelial growth factor (VEGF), which promote vascular hyperplasia and connective tissue proliferation in the nail beds. Hypoxia and chronic inflammation from tumors also contribute. Clubbing often accompanies lung malignancies and serves as a paraneoplastic sign. This fits with the client’s history of smoking and respiratory symptoms.

Choice C rationale: Chronic obstructive pulmonary disease (COPD) causes chronic hypoxemia due to airflow limitation and impaired gas exchange. Sustained low oxygen levels stimulate vasodilation and fibroblast proliferation in nail beds, causing clubbing. The long-term smoking history and recurrent infections support COPD as an underlying cause. Clubbing incidence in COPD varies but is associated with more severe disease and hypoxemia.

Choice D rationale: Chronic bronchitis, a subtype of COPD, involves chronic airway inflammation and mucus hypersecretion, leading to airflow obstruction and hypoxemia. Persistent hypoxia induces vascular and connective tissue changes in the digits, resulting in clubbed nails. The client’s history of recurrent respiratory infections and smoking is consistent with chronic bronchitis as a cause of clubbing.

Choice E rationale: Influenza (flu) is an acute viral respiratory infection causing fever, cough, and malaise but does not cause chronic hypoxia or persistent inflammation required for clubbing development. Nail changes develop over prolonged periods, making influenza an unlikely cause. Clubbing is not a known complication of acute viral infections like flu.

Correct Answer is A

Explanation

Choice A rationale

Shoulder flexion, which involves extending the arms up to 180 degrees beside the ears, represents the full normal range of motion for the glenohumeral joint. This movement assesses the combined function of the deltoid, supraspinatus, and biceps brachii muscles, indicating optimal mobility of the shoulder joint. A normal range is 0 to 180 degrees of flexion.

Choice B rationale

Holding arms up at 90 degrees while arms are pushed downward tests muscle strength against resistance, specifically of the deltoid. While an important component of shoulder assessment, it evaluates strength rather than the full range of motion. This maneuver assesses the integrity of the rotator cuff and surrounding musculature.

Choice C rationale

Alternating both index fingers to touch the tip of the nose accurately is a test of cerebellar function and coordination, assessing proprioception and fine motor control. This technique is not used to evaluate the range of motion of the shoulder joint. It helps identify neurological deficits, such as ataxia.

Choice D rationale

Extending arms straight out and holding without drifting, commonly known as the Romberg test (when standing) or pronator drift, assesses balance and subtle motor weakness, especially indicative of upper motor neuron lesions. This technique does not specifically measure the range of motion of the shoulder.

A. A dark line of pigmentation occurs along the midline of the abdomen. B. Weight gain becomes obvious as the hip circumference increases. C. The areolar color of the nipples changes from pink to dark brown. D. The development of breast buds will form under the nipples.

Correct Answer is D

Explanation

Choice A rationale

A dark line of pigmentation along the midline of the abdomen, known as linea nigra, is a physiological change primarily associated with pregnancy due to hormonal influences on melanocyte-stimulating hormone. It is not a typical indicator of the onset of puberty in females, where hormonal shifts initiate different developmental processes.

Choice B rationale

While weight gain and an increase in hip circumference do occur during puberty, these changes are often gradual and can be variable. They are secondary to hormonal changes, particularly estrogen's role in fat deposition, and are not the initial or most definitive sign of puberty's onset.

Choice C rationale

Areolar color changes, while influenced by hormonal fluctuations throughout a female's life, are not typically the primary or first discernible sign of pubertal onset. The initial breast development, specifically the formation of breast buds, precedes more significant changes in areolar pigmentation.

Choice D rationale

The development of breast buds, medically termed thelarche, is typically the first physical sign of puberty in females. This development is driven by increasing estrogen levels stimulating glandular tissue proliferation beneath the nipple, indicating the initial stages of sexual maturation.
