HESI Medical Surgical Exam
1. A client with Diabetes Insipidus (DI) is being cared for by a nurse. Which data warrants the most immediate intervention by the nurse?
- A. Serum sodium of 185 mEq/L (185 mmol/L)
- B. Dry skin with poor skin turgor
- C. Apical rate of 110 beats per minute
- D. Polyuria and excessive thirst
Correct answer: A
Rationale: A serum sodium level of 185 mEq/L (185 mmol/L) is dangerously high and indicates severe dehydration, requiring immediate intervention to prevent neurological damage. The other options are not as critical as high serum sodium levels, which can lead to serious complications such as seizures, coma, and death if not promptly addressed. Dry skin with poor skin turgor and polyuria with excessive thirst are common findings in clients with Diabetes Insipidus and should be managed but do not pose an immediate threat to the client's life. An apical heart rate of 110 beats per minute may indicate tachycardia, which could be related to dehydration but is not as urgent as addressing the severe hypernatremia.
2. You are assigned to teach a student how to suction an adult patient with a tracheostomy. Which of the following actions by the student would be incorrect?
- A. Pre-oxygenating the patient with a Resuscibag at 100% O2 several times before suctioning.
- B. Maintaining wall suction pressure at 110-150 mmHg.
- C. Not suctioning for greater than 10-15 seconds at a time.
- D. Applying gentle intermittent pressure and rotating the catheter during the insertion phase of suctioning.
Correct answer: D
Rationale: The incorrect action by the student is applying gentle intermittent pressure and rotating the catheter during the insertion phase of suctioning. This technique can cause trauma to the tracheal walls, increasing the risk of injury to the patient. It is essential to perform suctioning gently and without rotation to prevent complications in patients with a tracheostomy. Pre-oxygenating the patient, maintaining appropriate suction pressure, and limiting suctioning time are all correct actions when suctioning a patient with a tracheostomy.
3. A client with dysphagia is having difficulty swallowing medications. What is the nurse's best intervention?
- A. Crush the medications and mix them with applesauce.
- B. Encourage the client to drink water with each dose.
- C. Consult with the healthcare provider about switching to liquid medications.
- D. Offer the client soft foods to reduce difficulty swallowing.
Correct answer: C
Rationale: The best intervention for a client with dysphagia experiencing difficulty swallowing medications is to consult with the healthcare provider about switching to liquid medications. Liquid medications are often easier to swallow and can reduce the risk of choking and aspiration in clients with dysphagia. Crushing medications can alter their effectiveness, encouraging the client to drink water may not be sufficient, and offering soft foods is not directly related to improving medication swallowing.
4. During which stage of mitosis does the nuclear envelope begin to disappear and the chromosomes start attaching to the spindle forming along the cell's axis?
- A. Prometaphase
- B. Metaphase
- C. Anaphase
- D. Prophase
Correct answer: A
Rationale: The correct answer is A, Prometaphase. During prometaphase, the nuclear envelope disintegrates, and chromosomes start attaching to spindle fibers. In metaphase, chromosomes align in the middle of the cell. Anaphase is characterized by the separation of sister chromatids, and prophase involves the condensation of chromosomes and the beginning of spindle formation.
5. The nurse is teaching a group of clients about managing diabetes. Which of the following should be emphasized as a goal for all diabetics?
- A. Frequent exercise and weight control
- B. Prevent eye damage
- C. Keep insulin refrigerated at all times
- D. Prevent the development of complications
Correct answer: A
Rationale: The correct answer is A: Frequent exercise and weight control. These should be emphasized as a goal for all diabetics because they help prevent complications and manage blood sugar levels. Regular physical activity and maintaining a healthy weight are crucial in managing diabetes as they can improve insulin sensitivity, regulate blood sugar levels, and reduce the risk of cardiovascular complications. Choice B, preventing eye damage, is important but is more specific to diabetic retinopathy and not a general goal for all diabetics. Choice C, keeping insulin refrigerated, is essential for insulin storage but not a primary goal for all diabetics. Choice D, preventing the development of complications, is too broad and does not provide a specific actionable goal for all diabetics.
