A nurse is assessing a client who has Cushing's syndrome. Which of the following findings should the nurse expect?
Hyperpigmentation
Weight loss
Hypotension
Diaphoresis
The Correct Answer is A
A. Hyperpigmentation: This can occur due to increased production of melanin-stimulating hormones in some cases of Cushing's syndrome.
B. Weight loss: Weight loss is not a common feature of Cushing's syndrome. Instead, it usually presents with weight gain, particularly in the trunk and face (leading to "moon face" and "buffalo hump").
C. Hypotension: Hypotension is more common in Addison's disease due to the lack of cortisol and aldosterone. Cushing's syndrome is associated with hypertension due to excess cortisol increasing blood pressure.
D. Diaphoresis: Excessive sweating is not a common symptom of Cushing's syndrome.

Correct Answer is D
Explanation
A. Empyema: Empyema refers to the accumulation of pus in the pleural cavity, not a type of pneumonia. It is usually a complication of pneumonia rather than a description of the pneumonia itself.
B. Bronchopneumonia: Bronchopneumonia involves patchy consolidation that is usually scattered throughout the lung fields, not confined to a single lobe. It affects the bronchi and surrounding lung parenchyma.
C. Severe pneumonia: The term "severe pneumonia" describes the severity of the disease but does not specify the pattern of consolidation. It does not indicate whether the consolidation is lobar or patchy.
D. Lobar pneumonia: Lobar pneumonia is characterized by consolidation that involves an entire lobe of the lung. It typically presents with homogenous radiographic opacification of one or more lobes, often caused by pathogens such as Streptococcus pneumoniae.
Correct Answer is D
Explanation
A. Serum T4: In primary hypothyroidism, serum T4 levels are usually low due to decreased production by the thyroid gland.
B. Serum T3: Serum T3 levels are also typically low in primary hypothyroidism, as the thyroid gland produces less hormone overall.
C. Free T4: Free T4, the biologically active form of T4, is also usually low in primary hypothyroidism, reflecting decreased thyroid function.
D. Thyroid stimulating hormone (TSH): In primary hypothyroidism, the thyroid gland is underactive and does not produce enough thyroid hormones (T3 and T4). As a result, the pituitary gland releases more TSH in an attempt to stimulate the thyroid to produce more hormones, leading to elevated TSH levels.
