1. What is the primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT)?

• A. No need for regular INR monitoring
• B. Lower risk of bleeding
• C. Fewer dietary restrictions
• D. Longer half-life

Correct answer: A

Rationale: The primary advantage of prescribing rivaroxaban over warfarin for a patient with a history of deep vein thrombosis (DVT) is that rivaroxaban does not require regular INR monitoring. This eliminates the need for frequent blood tests to adjust the dosage, making it more convenient for patients to manage their anticoagulant therapy.

2. 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.

3. A 38-year-old male client collapsed at his outside construction job in Texas in July. His admitting vital signs to ICU are, BP 82/70, heart rate 140 beats/minute, urine output 10 ml/hr, skin cool to the touch. Pulmonary artery (PA) pressures are, PAWP 1, PAP 8/2, RAP -1, SVR 1600. What nursing action has the highest priority?

• A. Apply a hypothermia unit to stabilize core temperature.
• B. Increase the client's IV fluid rate to 200 ml/hr.
• C. Call the hospital chaplain to counsel the family.
• D. Draw blood cultures x3 to detect infection.

Correct answer: B

Rationale: The correct answer is to increase the client's IV fluid rate to 200 ml/hr. The client's vital signs indicate signs of shock and hypovolemia, making fluid resuscitation the priority to address these conditions. Improving intravascular volume is crucial to stabilize the client's blood pressure, heart rate, and urine output, ultimately improving organ perfusion and addressing the underlying issue of hypovolemia.

4. A client is admitted with diabetic ketoacidosis (DKA). Which assessment finding requires immediate intervention?

• A. Fruity breath odor.
• B. Blood glucose of 450 mg/dL.
• C. Deep, rapid respirations.
• D. Serum potassium of 5.2 mEq/L.

Correct answer: C

Rationale: The correct answer is C: Deep, rapid respirations (Kussmaul breathing). This is a sign of severe acidosis commonly seen in diabetic ketoacidosis (DKA) and requires immediate intervention. Kussmaul breathing helps to compensate for the metabolic acidosis by blowing off carbon dioxide. Prompt intervention is necessary to prevent further deterioration and potential respiratory failure. Fruity breath odor (Choice A) is a classic sign of DKA but does not require immediate intervention. While a blood glucose level of 450 mg/dL (Choice B) is high, it does not pose an immediate threat to the client's life. Serum potassium of 5.2 mEq/L (Choice D) is slightly elevated but not the most critical finding that requires immediate intervention in this scenario.

5. The client has acute kidney injury (AKI). Which assessment finding requires immediate intervention?

• A. Urine output of 50 ml in the last hour.
• B. Serum potassium of 6.2 mEq/L.
• C. Blood pressure of 150/90 mm Hg.
• D. Serum creatinine of 2.5 mg/dL.

Correct answer: B

Rationale: An elevated serum potassium level of 6.2 mEq/L in a client with AKI can lead to life-threatening cardiac arrhythmias, necessitating immediate intervention. Hyperkalemia is a serious complication in AKI as impaired kidney function can result in the accumulation of potassium in the blood, posing a risk of cardiac arrest. Prompt treatment to lower potassium levels is crucial to prevent cardiac complications in this situation.
