Nursing Elites

1. A client with newly diagnosed diabetes mellitus is being discharged home. Which statement indicates the client understands the instructions about managing blood glucose levels?

• A. I will test my blood glucose level once a week.
• B. I should eat a snack if my blood glucose is 70 mg/dl.
• C. If I feel shaky, I should take another dose of insulin.
• D. It's okay to skip a meal if I'm not hungry.

Correct answer: B

Rationale: Choice B is the correct answer. Eating a snack when blood glucose is low (70 mg/dl) can help prevent hypoglycemia. It is important for clients with diabetes to manage their blood glucose levels to prevent complications, and consuming a snack when glucose levels drop can help maintain the balance.

2. A client with liver cirrhosis is prescribed lactulose. What is the purpose of this medication?

• A. To lower blood sugar levels
• B. To reduce ammonia levels
• C. To treat liver inflammation
• D. To improve bile flow

Correct answer: B

Rationale: Lactulose is prescribed to reduce ammonia levels in clients with liver cirrhosis. Elevated ammonia levels can lead to hepatic encephalopathy, a serious complication of liver cirrhosis. Lactulose works by acidifying the colon, which in turn traps ammonia in the colon and helps its elimination from the body through stool, thereby reducing the risk of hepatic encephalopathy. Choice A is incorrect because lactulose does not lower blood sugar levels. Choice C is incorrect as lactulose is not used to treat liver inflammation. Choice D is incorrect as lactulose does not improve bile flow.

3. What action should the healthcare provider take to reduce the risk of vesicant extravasation in a client receiving intravenous chemotherapy?

• A. Administer an antiemetic before starting the chemotherapy.
• B. Instruct the client to drink plenty of fluids during the treatment.
• C. Keep the head of the bed elevated until the treatment is completed.
• D. Monitor the client's intravenous site hourly during the treatment.

Correct answer: D

Rationale: Monitoring the intravenous site hourly is essential to identify early signs of extravasation, such as swelling or pain, which can help prevent tissue damage. Prompt detection allows for immediate intervention, minimizing the risk of serious complications associated with vesicant extravasation.

4. The nurse is caring for a client who is receiving chemotherapy. Which laboratory result indicates that the client is at risk for infection?

• A. Hemoglobin level of 12 g/dL.
• B. Platelet count of 150,000/mm3.
• C. White blood cell count of 2,000/mm3.
• D. Serum creatinine level of 1.0 mg/dL.

Correct answer: C

Rationale: A white blood cell count of 2,000/mm3 is low and indicates leukopenia, which increases the client's risk for infection. Hemoglobin level and platelet count are not directly indicative of infection risk. Serum creatinine level is related to kidney function, not infection risk.

5. A 60-year-old man presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The presentation of a 60-year-old man with fatigue, polyuria, polydipsia, hyperglycemia, and ketonuria strongly suggests type 1 diabetes mellitus. Type 1 diabetes typically presents with acute symptoms due to absolute insulin deficiency, leading to hyperglycemia and ketonuria. Conversely, type 2 diabetes often presents more insidiously and is associated with relative insulin deficiency and insulin resistance. Diabetes insipidus, a condition characterized by excessive thirst and excretion of large amounts of dilute urine, is due to problems with antidiuretic hormone (ADH) and is not associated with hyperglycemia or ketonuria. Hyperthyroidism, while also presenting with symptoms like fatigue, does not typically manifest with hyperglycemia or ketonuria. Therefore, based on the clinical presentation and laboratory findings, the most likely diagnosis in this case is type 1 diabetes mellitus.
