HESI 799 RN Exit Exam Capstone Questions
Question 1 of 5
Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?
Correct Answer: B
Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.
Question 2 of 5
A client is diagnosed with Meniere's disease. Which problem should the nurse identify as most important in the plan of care?
Correct Answer: B
Rationale: Vertigo is the primary symptom of Meniere's disease and can lead to falls and other injuries. Ensuring safety and addressing the risk of injury is the nurse's top priority. While social isolation and impaired hearing are significant concerns associated with Meniere's disease, the immediate danger of falls due to vertigo takes precedence in the plan of care. Impaired verbal communication, although important, is not as urgent as preventing injuries caused by vertigo.
Question 3 of 5
The nurse is caring for a 24-month-old toddler who has sensory sensitivity, difficulty engaging in social interactions, and has not yet spoken two-word phrases. Which assessment should the nurse administer?
Correct Answer: B
Rationale: The Modified Checklist for Autism in Toddlers (M-CHAT) is specifically designed to screen for autism spectrum disorders in young children. It is appropriate for this child, given the signs of social and communication delays. The Peabody Picture Vocabulary Test (Choice A) assesses receptive vocabulary and may not capture the social and communication aspects seen in autism. The Wechsler Preschool and Primary Scale of Intelligence (Choice C) measures cognitive ability and may not address the social and communication delays. The Denver Developmental Screening Test (Choice D) is a broad developmental assessment tool, but the M-CHAT is more specific to screening for autism in this case.
Question 4 of 5
An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?
Correct Answer: B
Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.
Question 5 of 5
A client with Parkinson's disease is prescribed levodopa/carbidopa. The nurse instructs the client to take the medication with meals. Which rationale should the nurse provide for taking the medication with food?
Correct Answer: D
Rationale: The correct answer is D: 'It reduces gastrointestinal upset.' Levodopa/carbidopa can cause nausea and other gastrointestinal side effects. Taking the medication with food can help reduce these side effects and improve the client's comfort. Choices A, B, and C are incorrect because taking the medication with food does not primarily enhance effectiveness, improve absorption, or prevent orthostatic hypotension. The main reason for advising to take the medication with meals is to minimize gastrointestinal upset.
