ATI LPN

ATI NCLEX PN Predictor Test

1. A nurse is preparing to administer insulin to a client who has type 1 diabetes mellitus. After drawing up the medication, the nurse accidentally brushes the needle on the counter's surface. Which of the following actions should the nurse take?

A. Prepare a new dose of insulin injection
B. Administer the insulin as it is
C. Wipe the needle with an alcohol swab
D. Ask the provider for guidance

Correct answer: A

Rationale: The correct action for the nurse to take is to prepare a new dose of insulin injection. Accidentally brushing the needle on a contaminated surface can lead to infection risk. Administering the insulin as it is or just wiping the needle with an alcohol swab would not be sufficient to eliminate the risk of infection. Asking the provider for guidance is not necessary in this situation as the nurse can independently take the appropriate action to ensure patient safety.

2. A nurse on an acute unit has received a change of shift report for 4 clients. Which of the following clients should the nurse assess first?

A. A client who is 1 hr postoperative and has hypoactive bowel sounds.
B. A client who has a fractured left tibia and pallor in the affected extremity.
C. A client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses.
D. A client who has an elevated AST level following the administration of azithromycin.

Correct answer: B

Rationale: The correct answer is B because pallor in an extremity after a fracture could indicate compromised circulation, making it a priority for assessment. Choice A is not the priority as hypoactive bowel sounds in a client 1 hr postoperative, while concerning, do not indicate a life-threatening condition. Choice C, a client who had a cardiac catheterization 3 hr ago and has 3+ pedal pulses, indicates good perfusion and does not require immediate attention. Choice D, a client with an elevated AST level following the administration of azithromycin, may require further assessment but is not as urgent as the client with potential compromised circulation in choice B.

3. A client with hypokalemia is commonly expected to present with which of the following findings?

A. Muscle weakness
B. Nausea
C. Tingling sensation
D. Increased thirst

Correct answer: A

Rationale: The correct answer is A: Muscle weakness. Hypokalemia is characterized by low potassium levels in the blood, which can lead to muscle weakness. This occurs because potassium is essential for proper muscle function, and a deficiency can impair muscle strength. Nausea (choice B) is not a typical finding associated with hypokalemia. Tingling sensation (choice C) is more commonly linked to issues like nerve damage or poor blood circulation, rather than hypokalemia. Increased thirst (choice D) is not a direct symptom of hypokalemia; it is more commonly seen in conditions like diabetes or dehydration.

4. What are the key differences between systolic and diastolic heart failure?

A. Systolic: Reduced ejection fraction; Diastolic: Preserved ejection fraction
B. Systolic: Preserved ejection fraction; Diastolic: Reduced ejection fraction
C. Systolic: Right-sided heart failure; Diastolic: Left-sided heart failure
D. Systolic: Pulmonary congestion; Diastolic: Systemic congestion

Correct answer: A

Rationale: The correct answer is A. Systolic heart failure is characterized by reduced ejection fraction, meaning the heart is not pumping effectively. Diastolic heart failure, on the other hand, is characterized by preserved ejection fraction, indicating that the heart has difficulty relaxing and filling properly. Choices B, C, and D are incorrect because they do not accurately describe the key differences between systolic and diastolic heart failure.

5. What is the priority intervention when managing a client with delirium?

A. Administer antipsychotic medication to calm the client
B. Identify any reversible causes of delirium
C. Provide a low-stimulation environment
D. Administer sedative medication to control agitation

Correct answer: B

Rationale: The correct answer is to identify any reversible causes of delirium. Delirium is often caused by underlying issues such as infections, medication side effects, or metabolic imbalances. Addressing these root causes can help resolve delirium more effectively. Administering antipsychotic or sedative medications should not be the initial approach as they can worsen delirium in some cases. Providing a low-stimulation environment is beneficial but not the priority when reversible causes need to be addressed first.
