Fundamentals of Nursing HESI
1. A nurse is preparing to insert an IV catheter for an adult client. Which of the following actions should the nurse take?
- A. Choose the most distal site on the selected extremity
- B. Apply a cool compress to the selected extremity before insertion of the IV catheter
- C. Stroke the selected extremity before insertion of the IV catheter
- D. Place the tourniquet above the proposed insertion site
Correct answer: C
Rationale: When preparing to insert an IV catheter, stroking the extremity before insertion helps to visualize veins, making it easier to locate a suitable vein for catheter insertion. Choosing the most distal site on the extremity is correct because veins more distal are preferred for IV catheter insertion. Applying a cool compress to the extremity before insertion is unnecessary and not a standard practice. Placing the tourniquet below the proposed insertion site is incorrect; the tourniquet should be placed above the proposed insertion site to help engorge the veins for easier visualization and access.
2. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?
- A. Chest X-ray
- B. Sweat chloride test
- C. Pulmonary function test
- D. Sputum culture
Correct answer: B
Rationale: The correct answer is the sweat chloride test. This test is crucial in diagnosing cystic fibrosis as it measures the amount of chloride in sweat, which is typically elevated in individuals with cystic fibrosis. A chest X-ray (Choice A) may show characteristic findings like hyperinflation or bronchiectasis, but it is not a definitive diagnostic test for cystic fibrosis. Pulmonary function tests (Choice C) may help assess lung function but are not specific for cystic fibrosis. Sputum culture (Choice D) may be used to identify specific pathogens causing respiratory infections but is not a primary diagnostic test for cystic fibrosis.
3. The motive for a person who alters their diet due to religious convictions is most likely related to their ___.
- A. values
- B. body image
- C. ethnic heritage
- D. functional association
Correct answer: A
Rationale: The correct answer is A, 'values.' When individuals alter their diet due to religious convictions, it is primarily driven by their personal or cultural values associated with their faith. This choice reflects the strong influence that religious beliefs can have on dietary choices. Choice B, 'body image,' is incorrect because altering one's diet for religious reasons is more about spiritual beliefs than physical appearance. Choice C, 'ethnic heritage,' is incorrect as it pertains more to cultural background rather than religious convictions. Choice D, 'functional association,' is incorrect as it does not directly relate to the motivation behind altering one's diet for religious reasons.
4. Based on the interpretation of this strip, what action should be implemented first?
- A. Call a code.
- B. Start CPR.
- C. Administer IV fluids.
- D. Apply oxygen.
Correct answer: A
Rationale: The correct answer is A: 'Call a code.' In the context of ventricular fibrillation (V-Fib), immediate defibrillation is crucial. Calling a code is the first step to activating the emergency response team, including individuals trained to provide defibrillation. Starting CPR (Choice B) may be necessary but should follow defibrillation. Administering IV fluids (Choice C) and applying oxygen (Choice D) are important interventions in cardiac arrest cases, but in V-Fib, the priority is defibrillation to restore normal heart rhythm.
5. The healthcare professional is caring for a client with a chest tube. What is the most important action for the healthcare professional to take to ensure the chest tube is functioning properly?
- A. Milk the chest tube to ensure patency.
- B. Clamp the chest tube when moving the client.
- C. Ensure the water seal chamber is filled to the appropriate level.
- D. Secure the chest tube to the client's bed.
Correct answer: C
Rationale: Ensuring the water seal chamber is filled to the appropriate level is crucial to maintain the effectiveness of the chest tube drainage system. This step helps prevent air from entering the pleural space, ensuring proper lung re-expansion. 'Milking' the chest tube is not recommended as it can cause damage to the chest tube and surrounding tissues. Clamping the chest tube is not advisable as it can lead to tension pneumothorax. Securing the chest tube to the bed is important for stability but does not directly impact the functioning of the chest tube.
