HESI RN Medical Surgical Practice Exam
1. A healthcare professional is reading the chest x-ray report of a client who has just been intubated. The report states that the tip of the endotracheal tube lies 1 cm above the carina. The healthcare professional interprets that the tube is positioned above:
- A. The first tracheal cartilaginous ring
- B. The point where the larynx connects to the trachea
- C. The bifurcation of the right and left main stem bronchi
- D. The area connecting the oropharynx to the laryngopharynx
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.
2. A female client taking oral contraceptives reports to the nurse that she is experiencing calf pain. What action should the nurse implement?
- A. Determine if the client has also experienced breast tenderness and weight gain.
- B. Encourage the client to begin a regular, daily program of walking and exercise.
- C. Advise the client to notify the healthcare provider for immediate medical attention.
- D. Tell the client to stop taking the medication for a week to see if symptoms subside.
Correct answer: C
Rationale: Calf pain is indicative of thrombophlebitis, a serious, life-threatening complication associated with the use of oral contraceptives which requires further assessment and possibly immediate medical intervention.
3. The patient is receiving a high dose of tetracycline (Sumycin). Which laboratory values should the nurse monitor while caring for this patient?
- A. Blood urea nitrogen (BUN) and creatinine levels
- B. Complete blood counts
- C. Electrolytes
- D. Liver enzyme levels
Correct answer: A
Rationale: High doses of tetracyclines can lead to nephrotoxicity, especially when given along with other nephrotoxic drugs. Renal function tests, such as monitoring blood urea nitrogen (BUN) and creatinine levels, should be performed to assess for nephrotoxicity. Monitoring complete blood counts (choice B) is not directly related to tetracycline therapy. Checking electrolytes (choice C) is important but not the priority when monitoring for tetracycline-induced nephrotoxicity. Monitoring liver enzyme levels (choice D) is not typically indicated in the context of tetracycline therapy.
4. The client is being educated by the nurse on home blood glucose monitoring. Which of the following blood glucose measurements indicates hypoglycemia?
- A. 59 mg/dL (3.3 mmol/L)
- B. 75 mg/dL (4.2 mmol/L)
- C. 108 mg/dL (6 mmol/L)
- D. 119 mg/dL (6.6 mmol/L)
Correct answer: A
Rationale: A blood glucose level of 59 mg/dL (3.3 mmol/L) is considered hypoglycemia, which is an abnormally low blood sugar level. This level requires immediate attention as it can lead to symptoms such as confusion, shakiness, and even loss of consciousness if left untreated. Choices B, C, and D have blood glucose levels within the normal range or slightly higher, indicating euglycemia or normal blood sugar levels, and not hypoglycemia.
5. In a patient with type 1 diabetes, which of the following is a sign of diabetic ketoacidosis (DKA)?
- A. Polyuria
- B. Bradycardia
- C. Dry skin
- D. Tachycardia
Correct answer: D
Rationale: Tachycardia is a sign of diabetic ketoacidosis (DKA) in a patient with type 1 diabetes. In DKA, the body responds to hyperglycemia and dehydration by increasing heart rate. Polyuria (increased urination) is a symptom of diabetes but not specific to DKA. Bradycardia (slow heart rate) and dry skin are not typical signs of DKA; instead, tachycardia and other signs of volume depletion are more common.
