Medical Surgical Assignment Exam HESI

Correct Answer: C

Rationale: In a patient with multiple rib fractures, severe pulmonary contusions, and possible acute Respiratory Distress Syndrome (ARDS), tachypnea (rapid breathing) with dyspnea (shortness of breath) is a critical sign of respiratory distress that warrants immediate intervention by the nurse. Tachypnea and dyspnea indicate inadequate oxygenation and ventilation, which can lead to respiratory failure if not addressed promptly. The other options, such as apical pulse rate, core body temperature, and bruises over the chest area, are important assessments but do not directly indicate the immediate need for intervention in a patient with respiratory distress.

Correct Answer: C

Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.

Correct Answer: C

Rationale: The correct answer is C. Decreasing the number of cigarettes smoked per day is not sufficient for CAD prevention. Smoking cessation is crucial in reducing the risk of CAD. While increasing physical activity, eating a low-fat diet, and monitoring blood pressure regularly are all positive behaviors for CAD prevention, quitting smoking should be emphasized due to its significant impact on cardiovascular health.

Correct Answer: D

Rationale: With a CD4+ T cell count of 200 cells/microliter, the client's immune system is severely compromised, leading to opportunistic infections.

Correct Answer: B

Rationale: A temperature increase of 1.5�F (0.8�C) during a blood transfusion is a significant finding that can indicate a transfusion reaction, such as a febrile non-hemolytic reaction, which can progress to more severe reactions. It is crucial to report this immediately to the healthcare provider for further evaluation and intervention. Mild itching and rash (choice A) are common minor reactions to blood transfusions and can be managed appropriately without immediate concern. An increase in heart rate by 10 beats per minute (choice C) is within an acceptable range and may be a normal compensatory response to the transfusion. A slight headache (choice D) is a common complaint and is not typically associated with severe transfusion reactions; thus, it does not require immediate reporting compared to the temperature increase.
