A nurse is reviewing the laboratory results for a client who has Cushing's disease. The nurse should expect the client to have an increase in which of the following laboratory values?
Serum calcium level
Lymphocyte count
Serum glucose level
Serum potassium level
The Correct Answer is C
Rationale:
A. Serum calcium level: Cushing’s disease does not typically cause elevated calcium levels. Calcium levels are usually normal unless there is an underlying bone disorder or concurrent condition affecting calcium metabolism.
B. Lymphocyte count: Cortisol excess in Cushing’s disease suppresses the immune system, leading to lymphopenia rather than an increased lymphocyte count. A decreased lymphocyte count is more consistent with the disease process.
C. Serum glucose level: Elevated cortisol levels increase gluconeogenesis and decrease glucose uptake by cells, resulting in hyperglycemia. Clients with Cushing’s disease often exhibit elevated blood glucose as a direct effect of excess cortisol.
D. Serum potassium level: Cortisol has mineralocorticoid activity, promoting potassium excretion by the kidneys. As a result, clients with Cushing’s disease commonly have hypokalemia rather than increased serum potassium levels.

Correct Answer is ["A","B","D"]
Explanation
Rationale:
A. "Alternate the shoes you wear each day.": Rotating shoes helps prevent pressure points and reduces the risk of skin breakdown or foot ulcers, which is important for clients with diabetes who have impaired circulation and sensation.
B. "Apply synthetic fabric socks.": Synthetic or moisture-wicking socks help keep feet dry and prevent fungal infections, a common concern in clients with diabetes. Cotton or synthetic blends are preferred over thick wool or socks that retain moisture.
C. "Wear open-toe shoes": Open-toe shoes increase the risk of injury, infection, and trauma, which can lead to serious complications in diabetic clients. Closed, well-fitting shoes provide protection and support.
D. "Wash your feet daily with warm water and soap": Daily washing and gentle drying of the feet helps maintain hygiene, prevents infection, and allows early detection of cuts, cracks, or sores. Warm, not hot, water prevents burns in clients with neuropathy.
E. "Soak your feet for 1 hour each day.": Prolonged soaking can cause skin maceration, increasing the risk of infection and breakdown. Soaking is generally discouraged for clients with diabetes.
Correct Answer is A
Explanation
Rationale:
A. "Use an electric razor when shaving while taking this medication.": Warfarin is an anticoagulant that increases the risk of bleeding. Using an electric razor reduces the risk of cuts and subsequent bleeding, which is an important safety measure for clients on warfarin therapy.
B. "Take a dose of the medication every 5 minutes for a maximum of three doses": This instruction is inappropriate and unrelated to warfarin. Warfarin is taken orally once daily, and frequent dosing in short intervals could lead to serious bleeding complications.
C. "Avoid taking this medication with milk products.": Milk does not significantly affect warfarin absorption or activity. The client should be cautioned about foods high in vitamin K, such as leafy greens, because they can interfere with warfarin’s anticoagulant effect.
D. "This medication can cause hearing loss.": Hearing loss is not a known adverse effect of warfarin. The primary concerns are bleeding risks, bruising, and interactions with other medications or foods.
