HESI RN Exit Exam 2024 Capstone
1. A client is receiving IV fluid therapy for dehydration. Which assessment finding indicates that the client's fluid status is improving?
- A. Urine output increases to 50 mL/hour
- B. Client reports feeling more thirsty
- C. Blood pressure decreases from 120/80 to 110/70
- D. Heart rate increases from 80 to 100 beats per minute
Correct answer: A
Rationale: An increase in urine output is a positive sign that the client's hydration status is improving. It indicates that the kidneys are functioning well and that fluid therapy is effective. Increased urine output helps to eliminate excess fluid and waste products from the body. Choices B, C, and D are incorrect. Feeling more thirsty (choice B) is a sign of dehydration, not improvement. A decrease in blood pressure (choice C) and an increase in heart rate (choice D) are not typically indicative of improving fluid status during IV fluid therapy for dehydration.
2. A client with atrial fibrillation is prescribed warfarin. Which instruction should the nurse include in the teaching?
- A. Maintain a consistent intake of leafy green vegetables
- B. Use an electric razor when shaving
- C. Monitor blood pressure daily
- D. Avoid eating bananas and oranges
Correct answer: B
Rationale: Clients on warfarin are at increased risk of bleeding due to its anticoagulant effects. Using an electric razor reduces the risk of cuts and bleeding, which is an important safety precaution. While leafy greens should not be avoided, their intake should be consistent to maintain a stable level of vitamin K in the body. Monitoring blood pressure daily is important for other conditions but not directly related to warfarin therapy. Avoiding bananas and oranges is not a standard instruction for clients on warfarin.
3. Before a client with renal failure undergoes hemodialysis, what should the nurse assess?
- A. Check the client's potassium levels
- B. Review the client's medication list
- C. Assess the client's peripheral pulses
- D. Monitor the client's urine output
Correct answer: A
Rationale: The correct answer is to check the client's potassium levels. Potassium levels are crucial to assess before hemodialysis in a client with renal failure because hyperkalemia (high potassium) is a common complication in these patients. Hemodialysis aims to remove excess potassium from the blood, making it essential to monitor potassium levels to determine the need for appropriate interventions. Reviewing the client's medication list (Choice B) is important for overall care but is not as directly relevant to the immediate concerns before hemodialysis. Assessing peripheral pulses (Choice C) and monitoring urine output (Choice D) are important aspects of nursing assessment but are not as directly related to the specific preparation needed before hemodialysis in a client with renal failure.
4. During a thyroid storm, what is the nurse's priority intervention for a client experiencing increased heart rate and tremors?
- A. Administer antithyroid medications as prescribed.
- B. Administer a beta-blocker to control the heart rate.
- C. Monitor the client's temperature closely.
- D. Prepare the client for an emergency thyroidectomy.
Correct answer: A
Rationale: The correct answer is to administer antithyroid medications as prescribed during a thyroid storm. Antithyroid medications help control the overproduction of thyroid hormones, which is crucial in managing symptoms such as increased heart rate and tremors. These symptoms can be life-threatening if not promptly addressed. Administering a beta-blocker (Choice B) may help control the heart rate, but addressing the underlying cause with antithyroid medications is the priority. Monitoring the client's temperature (Choice C) is important but not the priority intervention during a thyroid storm. Lastly, preparing the client for an emergency thyroidectomy (Choice D) is not the initial intervention for managing symptoms of a thyroid storm.
5. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to lead poisoning?
- A. An 8-year-old who lives in a housing project.
- B. A 2-year-old who plays on aging playground equipment.
- C. An adolescent who works in a paint factory.
- D. A 10-year-old with Type 1 diabetes.
Correct answer: B
Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are at higher risk of lead poisoning due to their hand-to-mouth behavior and exploration of their environment. Aging playground equipment may have lead-based paint that can be ingested by the child. While children living in housing projects are also at risk due to lead-based paint in older buildings, the 2-year-old child playing on potentially lead-contaminated playground equipment is the most susceptible in this scenario. The adolescent working in a paint factory may face occupational hazards related to lead exposure, but the immediate risk from environmental sources is higher for the 2-year-old. Type 1 diabetes in a 10-year-old is not directly linked to an increased susceptibility to lead poisoning.
