HESI 799 RN Exit Exam Quizlet

Correct Answer: C

Rationale: In a client with septic shock, a heart rate of 120 beats per minute is a critical clinical finding that requires immediate intervention. A rapid heart rate can indicate worsening sepsis and inadequate tissue perfusion. Correcting the underlying cause of the tachycardia and stabilizing the heart rate is crucial in managing septic shock. The other options, while important, do not represent an immediate threat to the patient's condition. A blood pressure of 90/60 mmHg may be expected in septic shock, a temperature of 100.4�F is mildly elevated, and a urine output of 30 ml/hour, though decreased, may not be an immediate concern in the context of septic shock.

Correct Answer: C

Rationale: A serum bicarbonate level of 18 mEq/L indicates metabolic acidosis in a client with DKA, requiring immediate intervention. In DKA, the body produces excess ketones, leading to metabolic acidosis, which is reflected by a low serum bicarbonate level. Correcting the low serum bicarbonate is crucial to normalize the metabolic acidosis and improve the client's condition. While elevated serum glucose (choice A) and urine ketones (choice D) are characteristic of DKA, addressing the metabolic acidosis takes precedence. Serum potassium (choice B) levels may also need monitoring and management, but correcting the acidosis is the priority to prevent complications like cardiovascular collapse.

Correct Answer: C

Rationale: The correct answer is C. Crackles in the lungs indicate fluid overload, a common issue in heart failure patients. Immediate intervention is necessary to prevent worsening heart failure symptoms and potential complications. A heart rate of 60 beats per minute and a blood pressure of 100/60 mmHg are within normal ranges for many individuals and do not typically require immediate intervention in this context. The presence of a new murmur may be important to monitor but is not the priority when crackles in the lungs suggest fluid overload.

Correct Answer: C

Rationale: Subcutaneous emphysema is the assessment finding that requires immediate intervention in a client with a chest tube following a pneumothorax. Subcutaneous emphysema can indicate a pneumothorax recurrence or air leak, which can compromise respiratory function and lead to serious complications. Oxygen saturation of 94% may be concerning but does not require immediate intervention as it is still within an acceptable range. Crepitus around the insertion site is common after chest tube placement and may not always indicate a problem. A blood pressure of 110/70 mmHg is within normal limits and does not require immediate intervention in this context.

Correct Answer: A

Rationale: The child with a nosebleed (epistaxis) should be placed in a sitting position, leaning forward, to prevent blood from flowing down the throat. This position helps to control the bleeding and prevents the child from swallowing blood, which can cause nausea or vomiting. Choice B is incorrect because elevating the legs is not recommended for nosebleeds. Choice C is incorrect because lying on the side with the head slightly raised is not the optimal position for managing a nosebleed. Choice D is incorrect because tilting the head back can lead to blood flowing down the throat and potentially cause aspiration.
