A client with Addison's disease started taking hydrocortisone in a divided daily dose last week. It is most important for the nurse to monitor which serum laboratory value?

Osmolarity

Platelets

Albumin

Glucose

Answer and Explanation

The Correct Answer is D

Choice A reason: Osmolarity is a measure of the concentration of solutes in the blood. While it can be important in certain contexts, it is not the primary concern when monitoring a client with Addison's disease who is on hydrocortisone therapy.

Choice B reason: Platelets are a component of blood involved in clotting. Monitoring platelet count is important in certain conditions, but it is not the primary focus for a client with Addison's disease on hydrocortisone therapy.

Choice C reason: Albumin is a protein in the blood that helps maintain osmotic pressure and transport substances. While it is important to monitor albumin levels in some conditions, it is not the primary concern for a client with Addison's disease on hydrocortisone therapy.

Choice D reason: Glucose levels are crucial to monitor in clients with Addison's disease on hydrocortisone therapy. Hydrocortisone can affect glucose metabolism, potentially leading to hyperglycemia. Monitoring glucose levels helps ensure that the client's blood sugar remains within a safe range and allows for timely intervention if necessary.

Correct Answer is A

Explanation

Choice A reason: Substances that change a cell so that it becomes cancerous are potential sources of cancer. Carcinogens are agents that cause genetic mutations or damage to cells, leading to uncontrolled cell growth and the development of cancer. This definition accurately reflects the nature of carcinogens and their role in cancer development.

Choice B reason: Carcinogens are not substances that contain cancerous cells. Instead, they are substances or factors that can induce cancer by causing genetic mutations or cellular damage. The statement is incorrect because it misrepresents the nature of carcinogens.

Choice C reason: While it is true that some carcinogens are present in the environment, the statement that they cannot be avoided is not entirely accurate. Many carcinogens can be avoided or minimized through lifestyle choices, such as avoiding tobacco smoke, reducing exposure to harmful chemicals, and using protective measures against ultraviolet (UV) radiation. The statement is overly deterministic and does not account for preventive measures.

Choice D reason: Environmental factors such as sunlight and chemicals can contribute to the development of cancer, but they do not cause cancer to spread. The spread of cancer (metastasis) occurs when cancer cells break away from the original tumor and travel to other parts of the body. The statement conflates the causes of cancer with the mechanisms of cancer spread, making it inaccurate.

Correct Answer is ["56"]

Explanation

Step-by-Step Calculation:

Step 1: Convert liters to milliliters (mL) 2 liters × 1000 mL per liter = 2000 mL

Step 2: Calculate the total number of drops to be infused 2000 mL × 20 gtt per mL = 40000 gtt

Step 3: Convert hours to minutes 12 hours × 60 minutes per hour = 720 minutes

Step 4: Calculate the drops per minute 40000 gtt ÷ 720 minutes = 55.56

Step 5: Round to the nearest whole number 56 gtt/min

Answer: 56 gtt/min
