HESI RN Exit Exam

Correct Answer: B

Rationale: The correct answer is B. Alcohol-based hand rubs are effective with a shorter rub time, typically around 20-30 seconds. Standing at the bedside for 2 minutes to rub hands thoroughly is unnecessary and can lead to wastage of resources. It's essential for the nurse to educate the UAP on proper hand hygiene techniques to ensure efficient and effective infection control practices. Choices A, C, and D are incorrect because encouraging the UAP to remain in the client's room, discussing handwashing instead of hand rubs, and questioning glove use are not the most appropriate actions in this scenario.

Correct Answer: D

Rationale: Mucous plugging of the tracheostomy tube is the most concerning finding in a client with a tracheostomy and thick secretions. This can lead to airway obstruction, which requires immediate intervention to maintain a patent airway. Crepitus around the tracheostomy site may indicate subcutaneous emphysema but does not pose an immediate threat to the airway. A dry and cracked tracheostomy site may require interventions to promote healing but is not as urgent as mucous plugging. Yellowing of the skin around the tracheostomy site could indicate infection or impaired circulation, which should be addressed but does not pose the same immediate risk as airway obstruction.

Correct Answer: A

Rationale: The correct answer is A: Serum potassium level. In clients receiving erythropoietin therapy for chronic kidney disease, monitoring serum potassium levels is crucial due to the risk of developing hyperkalemia. Erythropoietin therapy can stimulate red blood cell production, leading to an increase in potassium levels. Monitoring potassium levels helps prevent complications associated with hyperkalemia, such as cardiac arrhythmias. Choices B, C, and D are incorrect because while hemoglobin levels are relevant for assessing the effectiveness of erythropoietin therapy, monitoring potassium levels is more critical due to the potential adverse effects of elevated potassium levels in CKD patients on this therapy.

Correct Answer: C

Rationale: A serum osmolarity of 320 mOsm/kg is the most concerning finding in a client with hyperglycemic hyperosmolar syndrome (HHS) as it indicates severe dehydration and hypertonicity. This high serum osmolarity level can lead to neurological complications and requires immediate intervention to prevent further deterioration. Serum glucose levels, blood pressure, and serum pH are important parameters to monitor in HHS, but a significantly elevated serum osmolarity poses a higher risk of complications and warrants urgent attention. High serum glucose levels, like 500 mg/dL, are expected in HHS but do not directly indicate the severity of dehydration. Blood pressure of 140/90 mmHg is within normal limits and may not be directly related to the acute complications of HHS. A serum pH of 7.30 suggests acidosis, which is important to address but may not be as immediately concerning as severe dehydration indicated by high serum osmolarity.

Correct Answer: C

Rationale: The correct intervention when a nurse finds an irregular heart rate in a newborn is to document the finding in the infant's record. An irregular heart rate is a common occurrence in newborns and does not necessarily require immediate medical intervention. Notifying the pediatrician immediately is unnecessary unless there are other concerning symptoms. Teaching the parents about congenital heart defects is not the priority in this situation. Applying oxygen via nasal cannula at 3 L/min is not indicated for an irregular heart rate without further assessment or medical indication.
