HESI RN Medical Surgical Practice Exam Questions
Question 1 of 5
A nurse administers scopolamine as prescribed to a client in preparation for surgery. For which side effect of this medication does the nurse monitor the client?
Correct Answer: D
Rationale: The correct answer is D: 'Complaints of feeling sweaty.' Scopolamine, an anticholinergic medication, commonly causes the side effect of decreased sweating, not increased urine output or pupil constriction. While dry mouth is a possible side effect, it is less likely than the altered sweating pattern. Therefore, the nurse should monitor the client for complaints of feeling sweaty due to the potential side effect of decreased sweating associated with scopolamine.
Question 2 of 5
A CD4+ lymphocyte count is performed on a client infected with HIV. The results of the test indicate a CD4+ count of 450 cells/L. The nurse interprets this test result as indicating:
Correct Answer: B
Rationale: A CD4+ count of 450 cells/L is below the normal range (500-1600 cells/mcL), indicating a decline in immune function in the client. Antiretroviral therapy is recommended when the CD4+ count falls below 500 cells/mcL or below 25%, or when the client displays symptoms of HIV. Therefore, the interpretation of this test result suggests that the client requires antiretroviral therapy to manage the HIV infection. Choices A, C, and D are incorrect because a CD4+ count of 450 cells/L does not signify improvement, discontinuation of therapy, or an effective response to treatment for HIV.
Question 3 of 5
A nurse reviews a client's urinalysis report. Which finding does the nurse recognize as abnormal?
Correct Answer: C
Rationale: The correct answer is C. The presence of ketones in the urine is abnormal. Ketones in the urine may indicate a state of ketosis, which is commonly seen in uncontrolled diabetes, fasting, or a low-carbohydrate diet. A normal pH range of urine is 4.5 to 7.8, making a pH of 6.0 within the normal range. An absence of protein is a normal finding in urine, as proteinuria (presence of protein) is abnormal. A specific gravity of 1.018 falls within the normal range of 1.016 to 1.022. Therefore, the presence of ketones is the abnormal finding in this scenario.
Question 4 of 5
A nursing student is suctioning a client through a tracheostomy tube while a nurse observes. Which action by the student would prompt the nurse to intervene and demonstrate the correct procedure? Select all that apply.
Correct Answer: A
Rationale: The correct suction pressure for an adult client with a tracheostomy tube is typically between 80 to 120 mm Hg. Suction should be applied intermittently during catheter withdrawal to avoid damaging the airway. Assessing breath sounds before suctioning is important to ensure the procedure is necessary. Placing the client in a supine position before suctioning can compromise their airway; instead, the head of the bed should be elevated to facilitate proper drainage and reduce the risk of aspiration. Therefore, setting the suction pressure to 60 mm Hg is incorrect and would prompt the nurse to intervene and correct the procedure.
Question 5 of 5
A client with a chest tube attached to a closed drainage system has undergone a chest x-ray, which revealed that the affected lung is fully reexpanded. The nurse anticipates that the next assessment of the chest tube system will reveal:
Correct Answer: A
Rationale: When the client's lung is fully reexpanded, the chest tube drainage system will no longer be actively draining, and there will be no fluctuation in the water seal chamber. Option B, continuous bubbling in the water seal chamber, indicates an air leak in the system, which is not expected when the lung is fully expanded. Option C, increased drainage in the collection chamber, would not be expected when the lung is reexpanded as there should be minimal to no drainage. Option D, continuous gentle suction in the suction control chamber, would not be appropriate when the lung is fully reexpanded and the chest tube is typically on a water seal system at this point to promote reexpansion and prevent air from entering the pleural space.
