Foundations and Adult Health Nursing Study Guide Answers

Correct Answer: B

Rationale: The presentation of a pruritic, erythematous rash with edematous plaques and vesicles on the hands and fingers in a patient with a history of exposure to detergents and frequent hand washing is most indicative of contact dermatitis. Contact dermatitis can be caused by direct contact with irritants such as detergents or chemicals, leading to skin irritation and inflammation. In this case, the history of exposure to detergents and hand washing suggests that the rash is likely due to irritant contact dermatitis. Atopic dermatitis, psoriasis, and pityriasis rosea do not typically present with the same pattern of rash in response to irritant exposure.

Correct Answer: C

Rationale: Type 2 diabetes mellitus is characterized by insulin resistance in the peripheral tissues and defective beta cell secretion with loss of insulin. In type 2 diabetes, there is typically not destruction of beta cells from an autoimmune mechanism that leads to lack of insulin and hyperglycemia as seen in type 1 diabetes mellitus. Instead, in type 2 diabetes, the pancreas initially produces insulin, but the body's cells become resistant to its effects. This results in hyperglycemia due to the inability of the body to properly regulate blood sugar levels. Therefore, choice C is not true for type 2 diabetes mellitus.

Correct Answer: B

Rationale: When communicating with a patient experiencing delirium, the nurse's priority is to provide clear and simple explanations to minimize confusion. Delirium can cause disorientation, confusion, and impaired cognitive function, making it difficult for the patient to understand complex information. Using simple language and clear explanations can help the patient better comprehend the situation and reduce anxiety. It is essential for the nurse to speak calmly, use reassuring gestures, and maintain a supportive presence to effectively communicate with a delirious patient. This approach can help establish a sense of trust and foster a therapeutic nurse-patient relationship during the challenging experience of delirium.

Correct Answer: D

Rationale: The symptoms described - muscle weakness, fatigue, constipation, hyperpigmentation of the skin, low serum cortisol levels, and elevated ACTH levels - are classic findings in Addison's disease. Addison's disease is a primary adrenal insufficiency characterized by the insufficient production of cortisol and, to some extent, aldosterone. The low cortisol levels result in symptoms such as muscle weakness, fatigue, and skin hyperpigmentation due to increased levels of ACTH stimulating melanin production. In contrast, in conditions like hyperthyroidism, hypothyroidism, and diabetes mellitus, the symptoms and laboratory findings would not fully align with those described in the patient in this scenario.
