HESI Fundamentals Study Guide
1. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which statement by the client indicates a need for further teaching?
- A. I will avoid foods high in vitamin K.
- B. I will take my medication at the same time every day.
- C. I will use a soft toothbrush to prevent gum bleeding.
- D. I can take aspirin if I have a headache.
Correct answer: D
Rationale: The correct answer is 'D: I can take aspirin if I have a headache.' This statement indicates a need for further teaching because aspirin can increase the risk of bleeding in clients taking warfarin. Clients on warfarin therapy should avoid taking aspirin or any other medications that can increase the risk of bleeding without consulting their healthcare provider. Choices A, B, and C are correct statements that demonstrate understanding of warfarin therapy and its potential side effects. Avoiding foods high in vitamin K helps maintain the effectiveness of warfarin, taking medication at the same time every day ensures consistent therapeutic levels, and using a soft toothbrush helps prevent gum bleeding, which can be a side effect of warfarin therapy.
2. What information would the nurse include in the preoperative plan of care for an infant with myelomeningocele?
- A. Positioning the infant supine with a pillow under the buttocks
- B. Covering the sac with saline-soaked nonadhesive gauze
- C. Wrapping the infant snugly in a blanket
- D. Applying a diaper to prevent fecal soiling of the sac
Correct answer: B
Rationale: The correct answer is B: Covering the sac with saline-soaked nonadhesive gauze. This intervention is essential in caring for an infant with myelomeningocele as it helps prevent infection and maintains a moist environment around the sac before surgical repair. Positioning the infant supine with a pillow under the buttocks (Choice A) may be suitable for comfort but is not directly related to managing the myelomeningocele. Wrapping the infant snugly in a blanket (Choice C) and applying a diaper (Choice D) are not recommended as they can increase the risk of infection and damage to the sac.
3. The nurse is caring for a client with a newly placed colostomy. Which statement by the client indicates a need for additional teaching?
- A. I will need to change the colostomy bag every day.
- B. I should avoid foods that can cause gas, such as beans and carbonated drinks.
- C. I need to empty the colostomy bag when it is one-third to one-half full.
- D. I will need to take care of the skin around the stoma to prevent irritation.
Correct answer: A
Rationale: The correct answer is A. Changing the colostomy bag every day is not necessary; it should be changed as needed, usually every 3-7 days. This statement indicates a need for additional teaching as frequent changes can irritate the skin and are not typically required. Choices B, C, and D are all correct statements regarding colostomy care. Avoiding gas-producing foods, emptying the bag when it is one-third to one-half full, and taking care of the skin around the stoma are all essential aspects of colostomy care to prevent complications and maintain skin integrity.
4. A client in the emergency department is being cared for by a nurse and has abdominal trauma. Which of the following assessment findings should the nurse identify as an indication of hypovolemic shock?
- A. Tachycardia
- B. Elevated blood pressure
- C. Warm, dry skin
- D. Decreased respiratory rate
Correct answer: A
Rationale: Tachycardia is a hallmark sign of hypovolemic shock. When a client experiences significant blood loss, the body compensates by increasing the heart rate to maintain adequate perfusion to vital organs. Elevated blood pressure is not typically seen in hypovolemic shock; instead, hypotension is a more common finding. Warm, dry skin is characteristic of neurogenic shock, not hypovolemic shock. Decreased respiratory rate is not a typical manifestation of hypovolemic shock, as the body usually tries to increase respiratory effort to improve oxygenation in response to hypovolemia.
5. Recurrent abdominal pain (RAP) is most often seen in school-age or adolescent children. The nurse should assess closely for what potential problem?
- A. Physical problems
- B. Relational problems
- C. Eating disorders
- D. Emotional problems
Correct answer: D
Rationale: The correct answer is D: 'Emotional problems.' Recurrent abdominal pain (RAP) in children is frequently associated with emotional factors rather than physical issues, relational problems, or eating disorders. Children may manifest emotional distress through physical symptoms like abdominal pain, making it crucial for nurses to assess for emotional problems as a potential cause.
