Nursing Elites

1. The client with DM is being instructed by the nurse about the importance of controlling blood glucose levels. The nurse should emphasize that uncontrolled blood glucose can lead to:

• A. Increased risk of heart disease and stroke.
• B. Improved wound healing.
• C. Reduced need for medication.
• D. Decreased risk of infection.

Correct answer: A

Rationale: The correct answer is A: Increased risk of heart disease and stroke. Uncontrolled blood glucose levels in clients with diabetes mellitus (DM) can lead to cardiovascular complications, such as heart disease and stroke. High blood glucose levels can damage blood vessels over time, increasing the risk of atherosclerosis and cardiovascular events. Choices B, C, and D are incorrect because uncontrolled blood glucose levels do not improve wound healing, reduce the need for medication, or decrease the risk of infection. In fact, uncontrolled blood glucose levels can impair wound healing, require more medications to manage symptoms, and increase the risk of infections due to compromised immune function.

2. The nurse is caring for a client with Addison's disease. The client exhibits signs of hypotension, dehydration, and confusion. The nurse should anticipate administering which of the following medications?

• A. Insulin
• B. Hydrocortisone
• C. Levothyroxine
• D. Methimazole

Correct answer: B

Rationale: In Addison's disease, the adrenal glands do not produce enough cortisol. Hydrocortisone is a glucocorticoid medication that is used to replace deficient cortisol levels in patients with Addison's disease. It helps stabilize blood pressure and fluid balance. Insulin (Choice A) is used to manage diabetes, not Addison's disease. Levothyroxine (Choice C) is a thyroid hormone replacement used to treat hypothyroidism, not Addison's disease. Methimazole (Choice D) is used in the treatment of hyperthyroidism, not Addison's disease.

3. A nurse is preparing to administer insulin to a client with DM. The nurse understands that the peak time for rapid-acting insulin, such as lispro (Humalog), is:

• A. 30 minutes to 1 hour after administration.
• B. 1 to 2 hours after administration.
• C. 2 to 4 hours after administration.
• D. 3 to 5 hours after administration.

Correct answer: A

Rationale: The correct answer is A: 30 minutes to 1 hour after administration. Rapid-acting insulins like lispro, such as Humalog, peak quickly within 30 minutes to 1 hour after administration. This peak time is crucial to monitor for potential hypoglycemia, which is most likely to occur during this period. Choice B is incorrect as it suggests a longer peak time for rapid-acting insulin, which is inaccurate. Choices C and D are also incorrect because they indicate even longer peak times, which do not align with the rapid onset and peak action of lispro insulin.

4. A male client with a tentative diagnosis of hyperosmolar hyperglycemic nonketotic syndrome (HHNS) has a history of type 2 diabetes that is being controlled with an oral diabetic agent, tolazamide (Tolinase). Which of the following is the most important laboratory test for confirming this disorder?

• A. Serum potassium level
• B. Serum sodium level
• C. Arterial blood gas (ABG) values
• D. Serum osmolarity

Correct answer: D

Rationale: Serum osmolarity is the most important laboratory test for confirming hyperosmolar hyperglycemic nonketotic syndrome (HHNS). HHNS is characterized by severe hyperglycemia and dehydration without ketoacidosis. Elevated serum osmolarity indicates increased solute concentration in the blood, which is a hallmark of HHNS. Serum potassium level (Choice A) is important in conditions like diabetic ketoacidosis rather than HHNS. Serum sodium level (Choice B) may be affected in HHNS but is not the primary test for confirming the disorder. Arterial blood gas (ABG) values (Choice C) are more useful in assessing acid-base status, which is not the primary concern in HHNS.

5. A client at risk for hypokalemia is being instructed by a nurse about foods high in potassium that should be included in the daily diet. The nurse determines that the client understands the food sources of potassium if the client states that the food item lowest in potassium is:

• A. Apples
• B. Carrots
• C. Spinach
• D. Avocado

Correct answer: A

Rationale: The correct answer is 'Apples.' Apples are the lowest in potassium among the given options. Carrots, spinach, and avocados are all higher in potassium content compared to apples. Carrots and spinach are vegetables known to have a moderate amount of potassium. Avocados, on the other hand, are a high-potassium fruit and would not be the lowest in potassium among the choices provided.
