Medical Surgical HESI

Correct Answer: B

Rationale: The correct answer is B, a 65-year-old fair-skinned male who is a construction worker. Fair-skinned individuals are at higher risk of developing skin cancer due to prolonged sun exposure. Construction workers are often exposed to the sun for long periods, further increasing the risk. Choices A, C, and D are less likely to develop skin cancer compared to choice B due to factors such as age, frequency of tanning bed use, and occupation.

Correct Answer: D

Rationale: In primary Raynaud phenomenon, the fingers go through a color sequence of pallor, cyanosis, and then redness when warmed. The burning sensation reported by the client indicates reperfusion. Continuing to monitor the fingers until the color returns to normal is appropriate in this situation as it ensures that the symptoms are resolving without the need for further intervention. Applying a cool compress could exacerbate the symptoms by causing vasoconstriction. Securing a pulse oximeter to monitor oxygen saturation is not necessary in this case as the issue is related to vasospasm rather than oxygenation. Reporting the finding to the healthcare provider is not urgent unless there are signs of complications or the symptoms do not improve with warming.

Correct Answer: B

Rationale: The correct answer is B: Risk for falls. In a postoperative client with hypovolemic shock, the most crucial problem to address is the risk for falls. Hypovolemic shock can result in dizziness and weakness, making the client prone to falling. Preventing falls is essential to avoid further injury or complications. Choices A, C, and D are not the top priority in this scenario. While infection, impaired skin integrity, and activity intolerance are important concerns, preventing falls takes precedence due to the immediate risk of injury associated with hypovolemic shock.

Correct Answer: C

Rationale: To deliver 1,000 units/hour from a solution with 25,000 units in 500 ml, the rate should be set to 20 ml/hour. This is calculated by determining that the solution has 50 units/ml (25,000 units / 500 ml = 50 units/ml) and then dividing the required 1,000 units/hour by 50 units/ml, resulting in 20 ml/hour. Therefore, the nurse should program the infusion pump to deliver heparin at 20 ml/hour. Choices A, B, and D are incorrect as they do not align with the calculated rate of 20 ml/hour.

Correct Answer: D

Rationale: One unit of PRBCs typically raises the hematocrit by 3%. Since the client received 4 units, the hematocrit is expected to increase by approximately 12% (4 units x 3% per unit). Therefore, the nurse should expect the client's hematocrit to be 29% after all PRBCs have been transfused. Choices A, B, and C are incorrect as they do not account for the cumulative effect of multiple PRBC units on the hematocrit level.
