Nursing Elites

1. 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.

2. A 60-year-old woman presents with fatigue, pruritus, and jaundice. Laboratory tests reveal elevated bilirubin and alkaline phosphatase levels. What is the most likely diagnosis?

• A. Hepatitis C
• B. Primary biliary cirrhosis
• C. Hemochromatosis
• D. Wilson's disease

Correct answer: B

Rationale: The symptoms of fatigue, pruritus, jaundice, and elevated bilirubin and alkaline phosphatase levels are classic features of primary biliary cirrhosis, an autoimmune liver disease. Hepatitis C typically presents with different symptoms and findings, such as specific viral markers. Hemochromatosis and Wilson's disease involve iron overload and copper accumulation, respectively, leading to distinct clinical and laboratory findings, which do not match the presentation described in this case.

3. The client with a history of heart failure is taking furosemide (Lasix). Which laboratory result should the nurse monitor closely?

• A. Serum sodium.
• B. Serum potassium.
• C. Serum calcium.
• D. Serum magnesium.

Correct answer: B

Rationale: Furosemide (Lasix) is a loop diuretic that can lead to potassium loss, causing hypokalemia. Monitoring serum potassium levels is crucial to prevent complications such as cardiac dysrhythmias associated with low potassium levels.

4. The healthcare provider is preparing to administer a blood transfusion. Which action is most important to ensure client safety?

• A. Check the client's vital signs before starting the transfusion.
• B. Verify the client's identity and blood compatibility.
• C. Administer the blood with normal saline.
• D. Monitor the client for the first 15 minutes of the transfusion.

Correct answer: B

Rationale: Verifying the client's identity and blood compatibility is the most critical step in ensuring client safety during a blood transfusion. This process helps prevent transfusion reactions by confirming that the correct blood product is being administered to the right patient.

5. An 82-year-old woman with no past medical history presents to your clinic complaining of arthritic symptoms. She is not taking any medications but needs something for her arthritis. You want to start her on a nonsteroidal anti-inflammatory drug (NSAID) but are concerned about her age and the risk of peptic ulcers. As she has to pay for her medications out-of-pocket and requests the most cost-effective option, what is the most appropriate treatment plan?

• A. Prescribe an inexpensive NSAID alone
• B. Prescribe an inexpensive NSAID and misoprostol
• C. Prescribe celecoxib
• D. Prescribe an inexpensive NSAID and sucralfate

Correct answer: A

Rationale: In this scenario, the most appropriate treatment plan would be to prescribe an inexpensive NSAID alone. While the elderly woman is at a higher risk of developing NSAID-related toxicity, prophylaxis with misoprostol or sucralfate is not recommended in the absence of a history of peptic ulcer disease or abdominal symptoms. Celecoxib, a selective COX-2 inhibitor, may be a more expensive option than traditional NSAIDs. Considering the patient's preference for the most inexpensive option and the lack of specific risk factors, starting with a standalone NSAID is the most suitable approach.
