HESI 799 RN Exit Exam

Correct Answer: B

Rationale: Obtaining a wound swab for culture and sensitivity is the most important intervention in this situation. It helps identify the presence of infection in the postoperative wound that could be causing the elevated temperature. By obtaining a wound swab, healthcare providers can determine the appropriate treatment needed to address any infection. Initiating contact isolation (Choice A) may be necessary in certain situations but is not the priority in this case. Assessing temperature (Choice C) is important but does not directly address the underlying cause of the elevated temperature. Using alcohol-based solutions for hand hygiene (Choice D) is a standard practice for infection control but is not the most crucial intervention in this scenario.

Correct Answer: C

Rationale: The correct answer is C. A tidal volume of 300 ml is concerning in a client with ARDS on mechanical ventilation because it indicates hypoventilation, which can lead to inadequate gas exchange and worsening respiratory status. This finding requires immediate intervention to optimize ventilation and oxygenation. Options A, B, and D are not as critical in this scenario. An oxygen saturation of 90% may be acceptable depending on the client's baseline condition and the target range set by the healthcare provider. A respiratory rate of 28 breaths per minute is slightly elevated but may not be immediately alarming. A blood pressure of 110/70 mmHg is within normal limits and does not require urgent intervention.

Correct Answer: A

Rationale: The correct answer is A: Stridor. Stridor is a high-pitched sound that indicates airway obstruction. When administering ceftriaxone sodium (Rocephin) intravenously, if the client develops stridor, it is a medical emergency requiring immediate intervention to maintain a patent airway. Nausea, headache, and pruritus are important to assess, but they do not pose an immediate threat to the client's airway and would not require the same level of urgent intervention as stridor.

Correct Answer: A

Rationale: Administering 50% dextrose IV push is the first priority in treating hypoglycemia to rapidly increase blood glucose levels. This choice is correct because in severe cases of hypoglycemia, when a client is admitted and unconscious or unable to swallow, intravenous administration of dextrose is crucial to quickly raise blood glucose levels. Option B, administering 15 grams of oral glucose, would be suitable for conscious clients with mild hypoglycemia who can swallow safely. Option C, rechecking blood glucose levels, should follow after immediate intervention to assess the response. Option D, administering a glucagon injection, is more suitable for cases where dextrose is not readily available or when the client does not respond to dextrose administration.

Correct Answer: B

Rationale: The correct answer is B. Moisturizing between the toes can create a moist environment that fosters fungal infections. Checking the feet daily for cuts or blisters (choice A) is correct in diabetes management to prevent complications. Wearing comfortable shoes that fit well (choice C) and avoiding walking barefoot (choice D) are also essential in preventing foot ulcers and injuries in diabetic patients.
