The nurse caring for a client reviews the medical record and determines the client is at risk for developing a potassium deficit because of which situation?
History of Addison's disease.
Has sustained tissue damage.
Uric acid level of 9.4 mg/dL.
Requires nasogastric suction.
The Correct Answer is D
The correct answer is choice D. Requires nasogastric suction.
Nasogastric suction removes gastric secretions that contain potassium, leading to a loss of potassium from the body.
This can cause hypokalemia, which is a low level of potassium in the blood.
Choice A is wrong because Addison’s disease causes hyperkalemia, which is a high level of potassium in the blood.
Choice B is wrong because tissue damage can release potassium from the cells into the blood, causing hyperkalemia.
Choice C is wrong because uric acid level is not related to potassium level.
Uric acid is a waste product of purine metabolism that can cause gout or kidney stones if elevated.

Correct Answer is D
Explanation
The client had a right radical mastectomy, which can lead to lymphedema, a buildup of fluid that can cause swelling in the arm. Using the client's left arm to obtain blood samples can help prevent injury to the affected arm and reduce the risk of lymphedema. Obtaining blood pressure readings with the client's left arm is also recommended. Range-of-motion exercises are important to prevent stiffness, and elevating the affected arm can help reduce swelling.
A: Obtaining blood pressure readings with the client's right arm can cause injury and increase the risk of lymphedema.
B: Limiting range-of-motion exercises can lead to stiffness and may not prevent lymphedema.
C: Keeping both arms below the level of the client's heart can help reduce swelling, but does not directly prevent lymphedema.
Correct Answer is D
Explanation
Palpable area of induration, greater than 10 mm (0.4 in) in diameter. This indicates a positive tuberculin skin test (TST) reaction for a person with no known risk factors for TB infection. A positive TST reaction means that the person has been infected with Mycobacterium tuberculosis, the bacterium that causes TB disease, and needs further testing to confirm the diagnosis and rule out active TB disease.
The other choices are not correct because:
- Choice A. Nonpalpable area of redness, less than 5 mm (0.2 in) in diameter. This indicates a negative TST reaction for any person, regardless of their risk factors for TB infection. A negative TST reaction means that the person has not been infected with Mycobacterium tuberculosis or has a very low level of immune response to the bacterium.
- Choice B. Area of ecchymosis, greater than 12 mm (0.5 in) in diameter. This indicates a bruise or bleeding under the skin, not a TST reaction. Ecchymosis is not caused by the injection of tuberculin purified protein derivative (PPD) into the skin, but by trauma or injury to the blood vessels.
- Choice C. Tenderness at the injection site. This indicates a mild local reaction to the injection of tuberculin PPD into the skin, not a TST reaction. Tenderness is not measured in millimeters of induration (firm swelling), which is the standard way of reading TST results.
