HESI 799 RN Exit Exam Capstone

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.

Correct Answer: D

Rationale: Reducing sodium intake is crucial in managing hypertension as high sodium levels can lead to fluid retention and increased blood pressure. While increasing water intake is beneficial for overall health, reducing sodium has a more significant impact on blood pressure. Regular exercise is important for cardiovascular health but does not have as direct an impact on blood pressure as sodium reduction. Avoiding alcohol is also important, but in terms of managing blood pressure, reducing sodium intake takes precedence.

Correct Answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

Correct Answer: B

Rationale: The correct answer is B: Assist the client with early ambulation. Early ambulation is a key intervention to prevent complications like deep vein thrombosis (DVT) and promote circulation after hip replacement surgery. It also helps with overall recovery and reduces the risk of complications related to immobility, such as muscle atrophy and pressure ulcers. Choice A is incorrect as bed rest should be avoided to prevent complications associated with immobility. Choice C, continuous passive motion therapy, is not the priority intervention immediately post-hip replacement surgery. Choice D, administering pain medication before activity, is important but not the priority intervention to prevent complications in this case.

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.
