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 client admitted with a diagnosis of sepsis has a central venous pressure (CVP) of 15 mm Hg. What should the nurse do first?

• A. Administer a fluid bolus of 500 ml.
• B. Notify the healthcare provider immediately.
• C. Administer a diuretic.
• D. Continue to monitor the CVP.

Correct answer: B

Rationale: A CVP of 15 mm Hg is higher than normal, indicating possible fluid overload or heart failure, which needs immediate attention. Notifying the healthcare provider is crucial as they can evaluate the client's condition, order appropriate interventions, and prevent potential complications.

3. A client with a new diagnosis of diabetes mellitus is learning to self-administer insulin. Which instruction should the nurse include?

• A. Store the insulin in the freezer.
• B. Administer the insulin at the same site each time.
• C. Rotate injection sites within the same region.
• D. Shake the vial vigorously before drawing up the insulin.

Correct answer: C

Rationale: The correct instruction for a client learning to self-administer insulin is to rotate injection sites within the same region. This practice helps prevent lipodystrophy, which is a condition characterized by fat tissue changes due to repeated injections in the same spot, and also ensures consistent absorption of insulin throughout the body. Storing insulin in the freezer is incorrect as it can lead to denaturation of the insulin. Administering the insulin at the same site each time can cause lipodystrophy and inconsistent absorption. Shaking the vial vigorously before drawing up the insulin is also incorrect as it can lead to insulin degradation.

4. The nurse is caring for a client with a history of deep vein thrombosis (DVT) who is receiving warfarin (Coumadin). Which laboratory value should the nurse monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Prothrombin time (PT) is monitored to ensure therapeutic levels of warfarin and prevent bleeding complications.

5. A client with heart failure is receiving intravenous furosemide (Lasix). Which assessment finding indicates that the medication is having the desired effect?

• A. Decreased peripheral edema.
• B. Elevated blood pressure.
• C. Increased heart rate.
• D. Decreased urine output.

Correct answer: A

Rationale: The correct answer is A: 'Decreased peripheral edema.' In a client with heart failure receiving furosemide, decreased peripheral edema indicates that the medication is effectively reducing fluid overload. Furosemide is a diuretic that helps the body eliminate excess fluid and salt through increased urine output, leading to a reduction in peripheral edema, which is a common symptom of heart failure. Monitoring and recognizing this improvement in edema are crucial in managing heart failure effectively.
