The multilumen pulmonary artery catheter allows the nurse to measure hemodynamic pressures at different points in the heart. When the tip enters the small branches of the pulmonary artery, the nurse can assess all of the following except:

Correct Answer: C

Rationale: The correct answer is C: Pulmonary artery obstructive pressure (PACP). The multilumen pulmonary artery catheter measures hemodynamic pressures in the heart. When the catheter tip enters small branches of the pulmonary artery, it can assess Central Venous Pressure (A), Pulmonary Artery Capillary Pressure (B), and Pulmonary Artery Wedge Pressure (D). Pulmonary artery obstructive pressure is not a standard hemodynamic measurement and is not assessed using this catheter. It is crucial to differentiate between the various pressures measured to accurately assess the patient's cardiac status.

Correct Answer: B

Rationale: The correct answer is B: Do not stop medication abruptly. Abruptly stopping propranolol can lead to rebound hypertension and potentially life-threatening complications. The nurse should emphasize the importance of gradual tapering under medical supervision to avoid adverse effects. A: Having potassium levels checked is not directly related to propranolol use for hypertension management. C: Changes in appetite are not specific to propranolol use and may not be a significant concern compared to abrupt cessation of the medication. D: Resuming usual daily activities is important but not as crucial as the correct instruction to avoid abrupt discontinuation of propranolol.

Correct Answer: A

Rationale: The correct answers are i. Keep the patient’s call light within reach, iii. Avoid use of throw rugs, and iv. Maintain the patient’s bed in a low position. 1. Keeping the call light within reach ensures the patient can easily call for assistance, reducing the risk of falls. 2. Avoiding throw rugs prevents tripping hazards that can lead to falls. 3. Maintaining the bed in a low position reduces the risk of injury if the patient falls out of bed. The incorrect choices: - Choice B includes answer 3 (Avoid use of throw rugs), which is correct, but also includes answer 6 (Provide a cane or walker for ambulation), which is not specific to fall prevention. - Choice C includes answer 2 (Apply a soft vest restraint when the patient is in bed), which can increase the risk of falls due to restricted movement. - Choice D includes answers that are not directly related to fall prevention, such as 2 (Apply a soft vest

Correct Answer: A

Rationale: The correct answer is A because exercising the bitten extremity can increase the spread of the venom. Choice B is correct as poisonous snake bites typically leave two fang marks. Choice C is correct as immediate severe pain and swelling are common symptoms of a poisonous snake bite. Choice D is incorrect as a tourniquet should not be used for snake bites as it can lead to complications such as tissue damage and increased risk of infection.

Correct Answer: A

Rationale: The correct answer is A: Maintain strict records of intake and output. This is the best way to assess fluid balance in a burn patient because it provides quantitative data on fluid intake and output, helping to monitor for fluid imbalance. Monitoring skin turgor (B) is unreliable in burn patients due to skin damage. Weighing the client daily (C) may not accurately reflect fluid balance changes. Checking for edema (D) is not specific to assessing fluid balance in burn patients. Maintaining intake and output records allows for precise monitoring and early detection of fluid shifts, making it the most appropriate choice.
