HESI RN Medical Surgical Practice Exam

Correct Answer: A

Rationale: To prevent the formation of renal calculi, it is essential to maintain adequate hydration as dehydration can contribute to the precipitation of minerals leading to stone formation. Therefore, the correct statement indicating understanding of the teaching is choice A. Increasing fluid intake helps dilute urine and reduces the risk of stone formation. Eliminating all sources of calcium is not recommended as calcium is essential for various bodily functions and eliminating it can lead to other health issues. Aspirin and aspirin-containing products do not directly cause kidney stones. Antibiotics are not used to prevent or treat renal calculi, as they are not caused by bacterial infections.

Correct Answer: B

Rationale: The correct pairing is a 58-year-old postmenopausal client who is not taking estrogen therapy with electrical stimulation. Electrical stimulation is used for clients with stress incontinence related to menopause and low estrogen levels. Exercise therapy improves pelvic wall strength and is not specifically for ambulation issues. Habit training is more effective for cognitively impaired clients, like those with Alzheimer's-type senile dementia. Bladder training requires the client to be alert, aware, and able to resist the urge to urinate, which may not be suitable for clients with cognitive impairments.

Correct Answer: B

Rationale: In nephrotic syndrome, there is significant renal loss of protein leading to hypoalbuminemia and edema formation. If glomerular filtration is normal or near normal, increased protein loss should be matched by an increased intake of protein. Therefore, the correct statement indicating a correct understanding of the nutritional therapy for this condition is increasing protein intake. Decreasing fat, decreasing carbohydrates, or increasing vitamin C intake is not necessary for addressing the underlying issues associated with nephrotic syndrome.

Correct Answer: C

Rationale: The carina is a cartilaginous ridge that separates the openings of the two main stem (right and left) bronchi. If an endotracheal tube is inserted past the carina, the tube will enter the right main stem bronchus due to the natural curvature of the airway. This positioning is dangerous as only the right lung will be ventilated. It can be identified as only the right lung will have breath sounds and rise and fall with ventilation. Choices A, B, and D are incorrect as they do not relate to the specific anatomical landmark mentioned in the scenario.

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.
