HESI 799 RN Exit Exam
1. A client with chronic kidney disease (CKD) is scheduled for a hemodialysis session. Which laboratory value should the nurse report to the healthcare provider before the procedure?
- A. Serum potassium of 5.5 mEq/L
- B. Blood urea nitrogen (BUN) of 40 mg/dl
- C. Serum potassium of 6.0 mEq/L
- D. Serum creatinine of 2.5 mg/dl
Correct answer: C
Rationale: A serum potassium level of 6.0 mEq/L is dangerously high for a client with chronic kidney disease (CKD) scheduled for hemodialysis. High potassium levels can lead to cardiac complications such as arrhythmias. Therefore, it is crucial to report this value to the healthcare provider before the procedure to prevent any potential serious complications. Choices A, B, and D are not as critical in the context of preparing for a hemodialysis session. Serum potassium levels above 6.0 mEq/L require immediate attention to ensure patient safety.
2. What most likely led to the 67-year-old woman who lives alone tripping on a rug in her home and fracturing her hip?
- A. Failing eyesight causing an unsafe environment.
- B. Renal osteodystrophy due to chronic renal failure.
- C. Osteoporosis due to hormonal changes.
- D. Cardiovascular changes leading to small strokes impairing mental acuity.
Correct answer: C
Rationale: The correct answer is C. Osteoporosis, caused by hormonal changes in later life, is the most likely predisposing factor for the fracture in the proximal end of her femur. Osteoporosis leads to reduced bone density, making bones more fragile and susceptible to fractures, especially in the elderly. Choices A, B, and D are less likely to directly lead to a hip fracture in this scenario. Failing eyesight (choice A) could contribute to the fall but is not the main predisposing factor for the fracture. Renal osteodystrophy (choice B) and cardiovascular changes (choice D) are less commonly associated with hip fractures compared to osteoporosis in elderly women.
3. A male client approaches the nurse with an angry expression on his face and raises his voice, saying, “My roommate is the most selfish, self-centered, angry person I have ever met. If he loses his temper one more time with me, I am going to punch him out!” The nurse recognizes that the client is using which defense mechanism?
- A. Denial
- B. Projection
- C. Rationalization
- D. Splitting
Correct answer: B
Rationale: The correct answer is B: Projection. In this scenario, the client is projecting his own feelings of anger onto his roommate by attributing his anger to the roommate. Projection involves shifting one's feelings, thoughts, or impulses onto another person. Denial (choice A) is the refusal to accept reality, Rationalization (choice C) involves justifying behaviors with logical reasons, and Splitting (choice D) is the inability to integrate positive and negative qualities of oneself or others.
4. When assessing an IV site used for fluid replacement and medication administration, the client complains of tenderness when the arm is touched above the site. Which additional assessment finding warrants immediate intervention by the nurse?
- A. Cool skin at the IV insertion site
- B. Presence of fluid leaking around the IV catheter
- C. Swelling above the IV site
- D. Red streaks tracking the vein
Correct answer: D
Rationale: The correct answer is D: "Red streaks tracking the vein." Red streaks indicate phlebitis, an inflammation of the vein that can lead to serious complications like infection or thrombophlebitis. Immediate intervention is required to prevent further damage. Choice A, cool skin at the IV insertion site, could indicate decreased circulation but is not as urgent as addressing phlebitis. Choice B, presence of fluid leaking around the IV catheter, may indicate infiltration or dislodgement of the catheter, requiring intervention but not as urgently as phlebitis. Choice C, swelling above the IV site, may suggest localized inflammation but doesn't pose an immediate threat like phlebitis does.
5. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving supplemental oxygen. Which assessment finding requires immediate intervention?
- A. Oxygen saturation of 90%
- B. Respiratory rate of 24 breaths per minute
- C. Use of accessory muscles
- D. Inspiratory crackles
Correct answer: C
Rationale: The correct answer is C. The use of accessory muscles is most concerning in a client with COPD receiving supplemental oxygen as it indicates increased work of breathing, requiring immediate intervention. Oxygen saturation of 90% is acceptable in a client with COPD. A respiratory rate of 24 breaths per minute is slightly elevated but not as critical as the use of accessory muscles. Inspiratory crackles may be present in clients with COPD due to underlying lung changes but do not require immediate intervention unless associated with other concerning symptoms.
