A nurse is monitoring the pulmonary artery wedge pressure (PAWP) for a client. The nurse should identify that a reading of 17 mm Hg is an indication of which of the following conditions?

Right ventricular failure

Fluid volume deficit

Mitral regurgitation

Afterload reduction

Answer and Explanation

The Correct Answer is C

Choice A Reason: This is incorrect because right ventricular failure would cause an increase in right atrial pressure and right ventricular end-diastolic pressure, but not in PAWP, which reﬂects left atrial pressure and left ventricular end- diastolic pressure.

Choice B Reason: This is incorrect because ﬂuid volume deficit would cause a decrease in PAWP, as there would be less blood volume in the pulmonary circulation.

Choice C Reason: This is correct because mitral regurgitation would cause an increase in PAWP, as the blood would back up into the left atrium and pulmonary veins due to the incompetent mitral valve.

Choice D Reason: This is incorrect because afterload reduction would cause a decrease in PAWP, as there would be less resistance to the left ventricular ejection and less blood volume in the pulmonary circulation.

Correct Answer is A

Explanation

Choice A Reason: Dobutamine is a positive inotropic agent that increases the contractility of the heart and improves cardiac output. This leads to increased renal perfusion and urine output, which reduces the ﬂuid overload and edema associated with heart failure. Therefore, this choice is correct.

Choice B Reason: Dobutamine does not have a direct eﬀect on blood glucose level. It may cause hyperglycemia as a side eﬀect, but this is not an indication of its eﬀectiveness. Therefore, this choice is incorrect.

Choice C Reason: Dobutamine may cause a slight decrease in blood pressure due to vasodilation, but this is not its main therapeutic eﬀect. A significant decrease in blood pressure may indicate hypovolemia, hypotension, or shock, which are adverse eﬀects of dobutamine. Therefore, this choice is incorrect.

Choice D Reason: Dobutamine also has a positive chronotropic eﬀect, which means it increases the heart rate. However, this is not a desired outcome for a client with heart failure, as it increases the oxygen demand of the heart and may worsen the condition. Therefore, this choice is incorrect.

A. 54 percent B. 36 percent C. 18 percent D. 9 percent

Correct Answer is A

Explanation

Choice A Reason: To calculate the total body surface area (TBSA) affected by burns using the Rule of Nines, the body is divided into sections, each representing a percentage of TBSA:

Front of one leg = 9%
Back of one leg = 9%
Front of one arm = 4.5%
Back of one arm = 4.5%

Now for the calculation:

Both legs (front and back):
- Front of both legs = 9% × 2 = 18%
- Back of both legs = 9% × 2 = 18%
- Total for both legs = 18% + 18% = 36%
Both arms (front and back):
- Front of both arms = 4.5% × 2 = 9%
- Back of both arms = 4.5% × 2 = 9%
- Total for both arms = 9% + 9% = 18%
Total TBSA:
- Legs (36%) + Arms (18%) = 54%

The nurse should document burns to 54% of the client's total body surface area (TBSA).

Choice B Reason:This choice is incorrect because it uses the original rule of nines for adults, not children. It also does not account for the depth and degree of the burns.

Choice C Reason: This choice is incorrect because it uses the original rule of nines for adults, not children. It also does not account for the depth and degree of the burns.

Choice D Reason: This choice is incorrect because it uses a random percentage that does not correspond to any rule or calculation.
