Correct Answer: D

Rationale: The correct answer is D because a multilumen pulmonary artery catheter can provide detailed information about preload, afterload, and cardiac output. Preload refers to the volume of blood in the ventricles at the end of diastole, afterload is the resistance the heart has to overcome to eject blood, and cardiac output is the amount of blood pumped by the heart per minute. This catheter allows for direct measurement of these parameters by monitoring pressures in the pulmonary artery. Choices A, B, and C are incorrect individually as they do not encompass the full range of information that can be obtained with a multilumen pulmonary artery catheter.

Correct Answer: C

Rationale: The correct answer is C: ABG. Monitoring ABG in Guillain-Barre Syndrome patients is crucial as they are at risk for respiratory complications like respiratory failure due to muscle weakness. ABG provides information on oxygenation, ventilation, and acid-base balance. Regular monitoring helps detect early signs of respiratory distress and guide appropriate interventions. A: BUN and creatinine are important for assessing renal function, but they do not directly relate to acute complications in Guillain-Barre Syndrome. B: Hgb and Hct are markers for anemia, which is not a common acute complication in Guillain-Barre Syndrome. D: Serum potassium levels are important, but ABG monitoring takes precedence in patients with Guillain-Barre Syndrome due to the risk of respiratory issues.

Correct Answer: B

Rationale: The correct answer is B because conducting the interview in a quiet environment, like the waiting area with the television turned off, reduces background noise and distractions for the patient with a hearing deficit. This allows for better communication and understanding. A: Conducting the interview in the patient's room with the door closed may still have distractions or noise from outside the room. C: Conducting the interview in the patient's room before administration of pain medication does not address the issue of reducing background noise for better communication. D: Conducting the interview in the waiting room while the occupational therapist is working on leg exercises introduces additional distractions and noise, making it harder for the patient with a hearing deficit to communicate effectively.

Correct Answer: B

Rationale: The correct answer is B: Ask her to demonstrate her ability to ambulate. This response is best because it allows the nurse to assess the patient's actual ability to walk safely to the bathroom. By observing her, the nurse can ensure her safety and prevent potential falls. This approach also respects the patient's autonomy while prioritizing her safety. Incorrect responses: A: Allowing her to ambulate unassisted solely for positive self-esteem overlooks the importance of assessing her actual capability and ensuring safety. C: Explaining that assistance will always be available may not address the immediate need for assessment and safety. D: Asking another staff member to assist without assessing the patient's ability herself does not allow the nurse to directly evaluate the patient's safety and independence.

Correct Answer: D

Rationale: The correct answer is D: Deficient knowledge. This nursing diagnosis is appropriate because educating the patient about hypertension, its management, lifestyle modifications, and medication adherence is crucial in improving outcomes. Activity intolerance (A) and impaired physical mobility (B) are not typically primary focuses for hypertension but may be secondary concerns. Ineffective airway clearance (C) is unrelated to hypertension. Therefore, D is the most relevant option for addressing the patient's needs.
