HESI LPN
Adult Health 2 Final Exam
1. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?
- A. Serum glucose of 180 mg/dL
- B. Blood pH of 7.30
- C. Positive urine ketones
- D. Serum bicarbonate of 25 mEq/L
Correct answer: C
Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.
2. What is the priority nursing responsibility when a 3-year-old child in a crib has a clamped jaw and is having a tonic-clonic seizure?
- A. Apply restraints.
- B. Administer oxygen.
- C. Protect the child from self-injury.
- D. Insert a plastic airway in the child’s mouth.
Correct answer: C
Rationale: During a tonic-clonic seizure, the priority nursing responsibility is to protect the child from self-injury. Applying restraints is not recommended during a seizure as it can lead to further harm. Administering oxygen may be necessary after the seizure to support oxygenation, but it is not the priority during the seizure itself. Inserting a plastic airway is also not indicated as the jaw is clamped, and the child should not have anything placed in the mouth during a seizure. Therefore, the correct action is to ensure the child's safety by protecting them from self-injury, preventing harm from uncontrolled movements and potential falls.
3. A client with a diagnosis of schizophrenia is prescribed lurasidone. The nurse should monitor the client for which potential side effect?
- A. Weight gain
- B. Dry mouth
- C. Nausea
- D. Headache
Correct answer: A
Rationale: The correct answer is A: Weight gain. When a client is prescribed lurasidone, monitoring for weight gain is essential as lurasidone can cause this side effect. Patients on lurasidone should have their weight monitored regularly to detect any changes that may occur. Options B, C, and D are not typically associated with lurasidone use, making them less likely to be a direct side effect of this medication.
4. A newborn presents with a pronounced cephalic hematoma following a birth in the posterior position. Which nursing diagnosis should guide the plan of care?
- A. Pain related to periosteal injury
- B. Impaired mobility related to bleeding
- C. Parental anxiety related to knowledge deficit
- D. Injury related to intracranial hemorrhage
Correct answer: C
Rationale: The correct nursing diagnosis to guide the plan of care for a newborn with a pronounced cephalic hematoma following a birth in the posterior position is 'Parental anxiety related to knowledge deficit.' This is appropriate because the parents may be worried about the appearance and potential complications of the cephalic hematoma. They may require education and reassurance from the nurse. Choices A, B, and D are incorrect because they do not address the emotional needs of the parents and the knowledge deficit they may have regarding the condition.
5. A female client with schizophrenia is experiencing auditory hallucinations. What is the most therapeutic response by the nurse?
- A. I don't hear any voices. They must be in your head.
- B. What are the voices telling you to do?
- C. You need to ignore the voices and focus on reality.
- D. I know the voices are real to you, but I don't hear them.
Correct answer: D
Rationale: Acknowledging the client's experience while gently presenting reality can help build trust and provide reassurance without reinforcing the hallucination.
