HESI 799 RN Exit Exam

Correct Answer: B

Rationale: The correct answer is B: History of cardiac arrhythmia. Clozapine can lead to severe cardiovascular problems, making it crucial to report any history of cardiac arrhythmia to the healthcare provider before administering the medication. Choices A, C, and D are less concerning in this context as they are not directly associated with potential serious complications related to clozapine use.

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: B

Rationale: The most important instruction for a client who recently underwent a tracheostomy is to teach tracheal suctioning techniques. Suctioning helps clear secretions and maintain an open airway, which is critical for the client's respiratory function and overall well-being. While communication tools, self-care, and cleaning the tracheostomy site are important aspects of care, ensuring proper suctioning techniques is crucial for preventing complications and ensuring the client's safety.

Correct Answer: A

Rationale: The correct answer is A: Stridor. Stridor indicates bronchospasm, a serious reaction that can compromise the client's airway. Immediate intervention is crucial to prevent further respiratory distress. Nausea, headache, and pruritus are potential side effects of ceftriaxone but are not as immediately life-threatening as airway compromise indicated by stridor.

Correct Answer: A

Rationale: The correct answer is to measure vital signs. Abrupt withdrawal of exogenous corticosteroids can precipitate adrenal insufficiency, potentially leading to shock. Monitoring vital signs is crucial in identifying any signs of adrenal insufficiency, such as hypotension or tachycardia. Auscultating breath sounds (choice B) may be important in other situations, such as respiratory conditions, but it is not the priority in this case. Palpating the abdomen (choice C) and observing the skin for bruising (choice D) are not directly related to the potential complications of corticosteroid withdrawal and adrenal insufficiency.
