HESI RN
HESI RN Exit Exam 2023
1. A client with rapid respirations and audible rhonchi is admitted to the intensive care unit because of a pulmonary embolism (PE). Low-flow oxygen by nasal cannula and weight-based heparin protocol are initiated. Which intervention is most important for the nurse to include in this client's plan of care?
- A. Evaluate blood clotting factors daily.
- B. Encourage incentive spirometry use.
- C. Administer pain medication as needed.
- D. Monitor for signs of bleeding.
Correct answer: A
Rationale: Evaluating blood clotting factors daily is crucial when a client is on heparin therapy to monitor for potential complications such as bleeding or clotting issues. This monitoring helps ensure that the heparin dose is within the therapeutic range and reduces the risk of bleeding or clotting complications. Encouraging incentive spirometry use is beneficial for preventing atelectasis and improving lung function, but in this scenario, monitoring blood clotting factors takes precedence. Administering pain medication as needed is important for the client's comfort but is not the priority in managing a pulmonary embolism. Monitoring for signs of bleeding is important due to heparin therapy, but evaluating blood clotting factors provides more specific information on the client's response to treatment.
2. A home health nurse is reviewing the laboratory results for several clients with heart failure. Which client finding would the nurse report to the health care provider immediately?
- A. Total cholesterol 190
- B. Glycosylated hemoglobin of 7%
- C. B-type natriuretic peptide 550 pg/ml (more than 100 is concerning)
- D. Potassium 3.7
Correct answer: C
Rationale: An elevated B-type natriuretic peptide level indicates worsening heart failure, requiring immediate attention. This biomarker reflects the severity of heart failure and helps guide treatment decisions. Total cholesterol and glycosylated hemoglobin are important for assessing cardiovascular risk and diabetes management but are not indicative of acute heart failure exacerbation. A potassium level of 3.7 falls within the normal range and does not suggest an immediate concern in the context of heart failure.
3. The parents of a 6-year-old recently diagnosed with asthma should be taught that symptoms of an acute episode of asthma are due to which physiological response?
- A. Inflammation of the mucous membrane and bronchospasm
- B. Increased mucus production and airway obstruction
- C. Hyperinflation of the lungs and alveolar collapse
- D. Bronchoconstriction and airway inflammation
Correct answer: D
Rationale: The correct answer is D: Bronchoconstriction and airway inflammation. During an acute asthma episode, bronchoconstriction and airway inflammation occur, leading to difficulty breathing. Choices A, B, and C are incorrect. Inflammation of the mucous membrane and bronchospasm (Choice A) are part of the pathophysiology of asthma but do not fully explain the symptoms during an acute episode. Increased mucus production and airway obstruction (Choice B) are also seen in asthma but are not the primary cause of acute symptoms. Hyperinflation of the lungs and alveolar collapse (Choice C) are not typical features of an acute asthma episode.
4. A nurse is assessing a newly admitted patient with chronic heart failure who forgot to take prescribed medications and seems confused. The patient complains of "just blowing up" and has peripheral edema and shortness of breath. Which assessment should the nurse complete first?
- A. Skin turgor
- B. Heart sounds
- C. Mental status
- D. Capillary refill
Correct answer: C
Rationale: Increases in extracellular fluid (ECF) can lead to swelling of cells in the central nervous system, initially causing confusion, which may progress to coma or seizures. Although skin turgor, capillary refill, and heart sounds also may be affected by increases in ECF, these are signs that do not have as immediate impact on patient outcomes as cerebral edema.
5. A client is admitted to the ER with DKA. In the acute phase, the priority nursing action is to prepare to:
- A. Administer regular insulin intravenously
- B. Administer 5% dextrose intravenously
- C. Correct the acidosis
- D. Apply an electrocardiogram monitor
Correct answer: A
Rationale: Administering regular insulin intravenously is the priority nursing action in the acute phase of DKA. Insulin helps to lower blood glucose levels by promoting cellular uptake of glucose and inhibiting ketone production. Administering dextrose would be counterproductive as it can worsen hyperglycemia. Correcting acidosis is important but usually follows insulin administration. Applying an electrocardiogram monitor is not the priority action in the acute management of DKA.
