1. A patient who is being treated for dehydration is receiving 5% dextrose and 0.45% normal saline with 20 mEq/L potassium chloride at a rate of 125 mL/hour. The nurse assuming care for the patient reviews the patient’s serum electrolytes and notes a serum sodium level of 140 mEq/L and a serum potassium level of 3.6 mEq/L. The patient had a urine output of 250 mL during the last 12-hour shift. Which action will the nurse take?

Correct answer: D

Rationale: The patient’s potassium level is within normal limits, but the decreased urine output indicates the patient should not receive additional IV potassium. Increasing potassium chloride to 40 mEq/L is not needed as the level is normal. Stopping the IV fluids is appropriate due to the decreased urine output, which suggests potential fluid overload. The nurse should notify the provider of the assessment findings for further management. Increasing the rate of fluids to 200 mL/hour is not recommended without addressing the decreased urine output first.

2. The nurse is taking the vital signs of a client after hemodialysis. Blood pressure is 110/58 mm Hg, pulse 66 beats/min, and temperature is 99.8°F (37.6°C). What is the most appropriate action by the nurse?

Correct answer: C

Rationale: After hemodialysis, it is crucial to monitor the client's temperature because the dialysate is warmed to increase diffusion and prevent hypothermia. The client's temperature might reflect the temperature of the dialysate. There is no need to administer fluids to increase blood pressure as the vital signs are within normal limits. Checking the white blood cell count or connecting the client to an ECG monitor is not necessary based on the information provided.

3. After a myocardial infarction, why is the hospitalized client taught to move the legs while resting in bed?

Correct answer: C

Rationale: The correct answer is C. Moving the legs helps prevent thrombophlebitis and blood clot formation by promoting venous return in clients on bed rest. This prevents stasis and clot formation in the lower extremities. Choices A, B, and D are incorrect because the primary goal of moving the legs is to prevent thrombophlebitis and blood clot formation, rather than preparing for ambulation, promoting elimination, or decreasing pressure ulcer formation. Ambulation preparation involves different exercises, urinary and intestinal elimination are not directly related to leg movements, and pressure ulcer prevention is more related to repositioning and skin care.

4. Which of the following conditions is most commonly associated with a high risk of stroke?

Correct answer: A

Rationale: Hypertension is the correct answer. Hypertension, also known as high blood pressure, is a major risk factor for stroke because it puts increased pressure on blood vessels in the brain, making them more prone to damage and increasing the likelihood of a stroke. While diabetes, obesity, and smoking are also risk factors for stroke, hypertension is the most commonly associated condition with a high risk of stroke due to its direct impact on the blood vessels.

5. A young adult client, admitted to the Emergency Department following a motor vehicle collision, is transfused with 4 units of PRBCs (packed red blood cells). The client's pretransfusion hematocrit is 17%. Which hematocrit value should the nurse expect the client to have after all the PRBCs have been transfused?

Correct answer: D

Rationale: The expected increase in hematocrit after transfusion is approximately 3% per unit of PRBCs. Since the client received 4 units, the expected increase would be 4 x 3% = 12%. Therefore, adding this to the pretransfusion hematocrit of 17% would result in an expected post-transfusion hematocrit of 29%. Choice A (0.19) is incorrect as it doesn't consider the incremental increase per unit of PRBCs. Choices B (0.09) and C (0.39) are also incorrect as they do not align with the expected increase in hematocrit following the transfusion of 4 units of PRBCs.
