Evolve HESI Medical Surgical Practice Exam

Correct Answer: A

Rationale: After checking the residual feeding contents, the nurse should pour the residual volume back into the stomach by removing the syringe bulb or plunger and then pouring the gastric contents, using the syringe, into the nasogastric tube. This helps ensure that the residual volume is reintroduced into the client's gastrointestinal tract. Option B is incorrect because discarding the residual volume without reinstilling it into the stomach can lead to inaccurate medication administration and potential electrolyte imbalances. Option C is incorrect as diluting the residual volume with water and injecting it under pressure can cause aspiration or discomfort for the client. Option D is incorrect because mixing the residual volume with the formula can alter the prescribed dosage and consistency, potentially affecting the client's nutritional intake and causing complications.

Correct Answer: A

Rationale: The correct answer is A. For an EEG, it is essential that the client's hair is clean, without any products like hairspray or gel, to ensure good electrode contact with the scalp. Choice B is not a concern as having breakfast is allowed before the test. Choice C, not taking an anticonvulsant, might be required for certain types of EEGs to capture accurate brain activity. Choice D, not drinking coffee, is not a specific requirement for an EEG preparation.

Correct Answer: D

Rationale: The client's dyspnea is most likely related to an air leak caused by a loose connection in the chest tube system. Checking the chest tube connections should be the initial action because correcting an air leak can quickly resolve the client's symptoms. If a leak is found and corrected, the dyspnea should improve. Assessing the client's vital signs (Option A) is important, but addressing the potential cause of dyspnea takes precedence. Monitoring the amount of drainage (Option B) is necessary for assessing the client's overall condition, but in this case, the dyspnea is likely due to an air leak. Checking the client's lung sounds (Option C) is essential for respiratory assessment, but addressing the air leak should be the immediate priority to ensure adequate lung expansion and oxygenation.

Correct Answer: B

Rationale: The correct answer is 'B: Overflow incontinence.' The most common manifestation of urethral stricture after a urologic procedure is obstruction of urine flow. This obstruction can lead to overflow incontinence, which is the involuntary loss of urine when the bladder is distended. Severe pain is not typically associated with an obstruction of urine flow. Hypotension is unrelated to this issue. Blood-tinged urine is not a direct indication of an obstruction of urine flow but may indicate other conditions like trauma or infection.

Correct Answer: A

Rationale: The patient's presentation of tachycardia, hypotension, lethargy, muscle weakness, and gastroenteritis suggests hyponatremia. Hyponatremia is characterized by a serum sodium level below the normal range of 135-145 mEq/L. A serum sodium level of 126 mEq/L falls significantly below this range, indicating hyponatremia. Choice B (140 mEq/L) and Choice C (145 mEq/L) are within the normal range for serum sodium levels and would not explain the patient's symptoms. Choice D (158 mEq/L) is above the normal range and would indicate hypernatremia, which is not consistent with the patient's presentation.
