HESI 799 RN Exit Exam Capstone
1. An unresponsive male victim of a diving accident is brought to the emergency department where immediate surgery is required to save his life. No family members are available. What action should the nurse take first?
- A. Ask the friend to sign an informed consent.
- B. Notify the unit manager that a court order is needed.
- C. Continue providing life support until a guardian is found.
- D. Proceed with surgery preparation without consent.
Correct answer: D
Rationale: In emergency situations where immediate surgery is required to save a patient's life and no family members are available, consent can be waived to proceed with necessary interventions. The priority in this scenario is to proceed with surgery preparation without waiting for consent, as any delay could jeopardize the patient's life. Asking the friend to sign informed consent or notifying the unit manager for a court order would cause unnecessary delays, which are not advisable in this critical situation. Continuing life support until a guardian is found is not the most appropriate action when immediate surgical intervention is necessary.
2. What are the primary pathophysiological mechanisms responsible for ascites in liver failure?
- A. Decreased liver enzymes.
- B. Increased hydrostatic pressure in portal circulation.
- C. High bilirubin levels.
- D. Fluid shifts due to decreased serum proteins.
Correct answer: B
Rationale: The correct answer is B: Increased hydrostatic pressure in portal circulation. Ascites in liver failure is primarily caused by fluid shifts from the intravascular space to the interstitial space due to increased hydrostatic pressure in the portal circulation. Choice A is incorrect as ascites is not caused by decreased liver enzymes. Choice C is incorrect as high bilirubin levels are not the primary mechanism for ascites in liver failure. Choice D is incorrect as fluid shifts in ascites are due to decreased serum proteins, not increased serum proteins.
3. When conducting diet teaching for a client on a postoperative full liquid diet, which foods should the nurse encourage the client to eat?
- A. Yogurt, milk, and pudding
- B. Tea, lentils, and potato soup
- C. Ice cream, broth, and fruit smoothies
- D. Orange juice, mashed potatoes, and soft cheese
Correct answer: A
Rationale: A full liquid diet includes foods that are liquid or will turn liquid at room temperature. Yogurt, milk, and pudding are appropriate choices as they align with the consistency requirements of a full liquid diet. Choices B, C, and D are incorrect. Tea, lentils, potato soup, ice cream, fruit smoothies, orange juice, mashed potatoes, and soft cheese are not typically part of a full liquid diet. These options either contain solid elements or are not in liquid form, which makes them unsuitable for a postoperative full liquid diet.
4. A client is admitted with ascites, malnutrition, and recent complaints of spitting up blood. What assessment finding warrants immediate intervention by the nurse?
- A. Capillary refill of 8 seconds
- B. Bruises on arms and legs
- C. Round and tight abdomen
- D. Pitting edema in lower legs
Correct answer: C
Rationale: A round and tight abdomen suggests fluid accumulation from ascites, which could signal a more severe underlying condition requiring immediate intervention. This finding indicates increased intra-abdominal pressure, which can lead to respiratory compromise or other serious complications. Capillary refill time, bruises on arms and legs, and pitting edema in the lower legs are important assessments but do not directly indicate the need for immediate intervention as a round and tight abdomen does in this case.
5. The nurse is planning to administer two medications at 0900. Which property of the drugs indicates a need to monitor the client for toxicity?
- A. Short half-life
- B. High therapeutic index
- C. Highly protein-bound
- D. Low bioavailability
Correct answer: C
Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.
