HESI RN CAT Exit Exam
1. The nurse assesses a client who is receiving an infusion of 5% dextrose in water with 20 mEq of potassium chloride. The client has oliguria and a serum potassium level of 6.5 mEq/L. What action should the nurse implement first?
- A. Notify the healthcare provider of the laboratory results
- B. Decrease the rate of the IV infusion
- C. Stop the infusion
- D. Administer sodium polystyrene sulfonate (Kayexalate)
Correct answer: C
Rationale: The correct action for the nurse to implement first is to stop the infusion. Stopping the infusion is crucial to prevent further potassium from being administered, which can exacerbate the client's hyperkalemia. Notifying the healthcare provider of the laboratory results (Choice A) can be done after taking immediate action to stop the infusion. Decreasing the rate of the IV infusion (Choice B) may not be sufficient to address the high potassium level quickly. Administering sodium polystyrene sulfonate (Kayexalate) (Choice D) is not the initial action for managing hyperkalemia; stopping the potassium infusion takes precedence.
2. Which assessment finding is most indicative of deep vein thrombosis (DVT) in a client's right leg?
- A. Dorsiflexes the right foot and left on command
- B. A 3 by 5 cm ecchymosis area covering the right calf
- C. Right calf is 3 cm larger in circumference than the left
- D. Bilateral lower extremity has 3+ pitting edema
Correct answer: C
Rationale: The correct answer is C because a significant increase in the circumference of the right calf compared to the left calf is a classic sign of deep vein thrombosis (DVT). Option A is incorrect as dorsiflexing the right foot and left on command does not specifically indicate DVT. Option B describes an ecchymosis area which is more indicative of a bruise rather than DVT. Option D suggests bilateral lower extremity edema, which is not specific to DVT and can be seen in various conditions such as heart failure or renal issues.
3. The nurse preceptor is orienting a new graduate nurse to the critical care unit. The preceptor asks the new graduate to state symptoms that most likely indicate the beginning of a shock state in a critically ill client. What findings should the new graduate nurse identify?
- A. Tachycardia, mental status change, and low urine output
- B. Warm skin, hypertension, and constricted pupils
- C. Bradycardia, hypotension, and respiratory acidosis
- D. Mottled skin, tachypnea, and hyperactive bowel sounds
Correct answer: A
Rationale: The correct answer is A: Tachycardia, mental status change, and low urine output are early signs of shock. Tachycardia is the body's compensatory mechanism to maintain perfusion, mental status changes can indicate decreased cerebral perfusion, and low urine output reflects poor renal perfusion. Choices B, C, and D are incorrect. Warm skin, hypertension, and constricted pupils are not typical findings in the early stages of shock. Bradycardia, hypotension, and respiratory acidosis are more indicative of late-stage shock. Mottled skin, tachypnea, and hyperactive bowel sounds can be seen in various conditions but are not specific early signs of shock.
4. A client admitted to the hospital for depression is escorted to a private room. Prior to leaving the room, what intervention is most important for the nurse to implement?
- A. Explain the program's guidelines
- B. Search all personal belongings
- C. Initiate psychosocial assessment
- D. Review the healthcare provider's prescription
Correct answer: B
Rationale: Searching personal belongings is essential to ensure the safety of the client by preventing access to items that could be used for self-harm. While explaining the program's guidelines (Choice A) and initiating a psychosocial assessment (Choice C) are important aspects of care, the immediate concern in this situation is the safety of the client. Reviewing the healthcare provider's prescription (Choice D) is important for providing appropriate treatment but is not as urgent as ensuring the client's safety.
5. A healthcare provider is assessing a client who is receiving treatment for dehydration. Which assessment finding indicates that the client is responding to the treatment?
- A. Dry mucous membranes
- B. Increased urine output
- C. Decreased skin turgor
- D. Elevated heart rate
Correct answer: B
Rationale: Increased urine output is a positive sign indicating that the client is responding to the treatment for dehydration. It suggests that the client's kidneys are functioning better, helping to eliminate excess fluid and waste products from the body. Dry mucous membranes (Choice A) are a sign of dehydration, not improvement. Decreased skin turgor (Choice C) and elevated heart rate (Choice D) are also symptoms of dehydration and do not indicate a positive response to treatment.
