Practice HESI Fundamentals Exam
1. The patient is being taught about flossing and oral hygiene. What instruction will the nurse include in the teaching session?
- A. Using waxed floss helps prevent bleeding
- B. Flossing removes plaque and tartar from the teeth
- C. Flossing at least 3 times a day is beneficial
- D. Applying toothpaste before flossing is harmful
Correct answer: B
Rationale: The correct answer is B. Flossing is essential for removing plaque and tartar between teeth, contributing to better oral hygiene. Choice A is not entirely accurate as waxed floss may not solely prevent bleeding. Flossing three times a day, as mentioned in choice C, can be excessive and unnecessary, while choice D is incorrect as applying toothpaste before flossing is not harmful but might not provide additional benefits.
2. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
3. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
4. To minimize the side effects of vincristine (Oncovin) that a client is receiving, what does the LPN/LVN expect the dietary plan to include?
- A. Low in fat
- B. High in iron
- C. High in fluids
- D. Low in residue
Correct answer: C
Rationale: The correct answer is to include a diet high in fluids to help minimize the side effects of vincristine. High fluid intake is important in managing potential side effects such as constipation, which is a common issue associated with vincristine therapy. Options A, B, and D are incorrect. A diet low in fat or high in iron is not specifically indicated for managing vincristine side effects. Additionally, a diet low in residue is not directly related to addressing vincristine side effects.
5. A client receiving chlorpromazine HCL (Thorazine) is in psychiatric home care. During a home visit, the nurse observes the client smacking her lips alternately with grinding her teeth. The nurse recognizes this assessment finding as what?
- A. Dystonia
- B. Akathisia
- C. Bradykinesia
- D. Tardive dyskinesia
Correct answer: D
Rationale: The correct answer is D: Tardive dyskinesia. Tardive dyskinesia is a potential side effect of long-term antipsychotic use, characterized by involuntary movements like lip smacking and repetitive, purposeless movements. Choice A, dystonia, presents with sustained or repetitive muscle contractions. Choice B, akathisia, involves motor restlessness and a compelling need to be in constant motion. Choice C, bradykinesia, refers to slowness of movement typically seen in Parkinson's disease, not lip smacking and teeth grinding, which are indicative of tardive dyskinesia.
