A nurse is monitoring a client who has diabetes mellitus and a glucose level of 384 mg/dl. (74 to 106 mg/dL). Which of the following findings should the nurse identify as an indication of metabolic acidosis?
Positive Trousseau's sign
Dizziness upon standing
Tingling of the fingers
Increased respiratory rate
The Correct Answer is D
Choice A Reason:
Positive Trousseau's sign is incorrect. Trousseau's sign is associated more with calcium imbalances, particularly hypocalcemia, and is assessed by inflating a blood pressure cuff on the arm to induce carpal spasm. It's not a specific indicator of metabolic acidosis related to high glucose levels in diabetes mellitus.
Choice B Reason:
Dizziness upon standing is incorrect. Dizziness upon standing, also known as orthostatic hypotension, is more commonly associated with blood pressure changes upon position changes. While it can occur in various conditions, it's not a specific indicator of metabolic acidosis in this context.
Choice C Reason:
Tingling of the fingers is incorrect. Tingling sensations, known as paresthesia, can occur due to various reasons, including nerve damage related to chronic high blood sugar levels in diabetes (diabetic neuropathy). However, it's not a direct and specific indicator of metabolic acidosis caused by high glucose levels in diabetes mellitus.
Choice D Reason:
Increased respiratory rate is correct. Metabolic acidosis in a diabetic individual can trigger compensatory mechanisms, such as increased respiratory rate (Kussmaul respirations), as the body tries to eliminate excess acids through respiration to help regulate the acid-base balance. This increased respiratory rate is an attempt to blow off carbon dioxide (a potential acidic byproduct) and decrease the acidity in the blood.

Correct Answer is A
Explanation
Choice A Reason:
The client's fingers are cool to the touch is correct. Coolness of the fingers within a short time after a cast application can indicate compromised circulation or potential compartment syndrome, which requires urgent attention to prevent tissue damage or loss of function. It suggests impaired blood flow to the fingers, which is a serious concern requiring immediate evaluation by the provider.
Choice B Reason:
The client reports severe itching under the cast is incorrect. While itching can be uncomfortable, it might not pose an immediate threat. Itching can commonly occur as the skin heals and can be managed through non-invasive means.
Choice C Reason:
The client's capillary refill is 3 seconds is incorrect. A capillary refill of 3 seconds is slightly prolonged but doesn't typically indicates an immediate emergency. However, if this finding worsens or if combined with other concerning symptoms, it might warrant further assessment.
Choice D Reason:
The client reports increased pain at the area of the fracture is incorrect. Increased pain after a cast application can be expected initially, especially within 2 hours of the procedure. However, persistent or severe pain could indicate issues like poor alignment, swelling, or other complications. While it's important to address pain, it might not require immediate reporting unless accompanied by other concerning symptoms.
Correct Answer is C
Explanation
Choice A Reason:
Keeping both arms below the level of the client's heart doesn't specifically address the prevention of lymphedema and might not be necessary for this purpose.
Choice B Reason:
Limiting range-of-motion exercises with the affected arm could potentially contribute to stiffness and reduced function, but appropriate and gradual range-of-motion exercises are generally recommended to prevent lymphedema.
Choice C Reason:
Using the client's left arm to obtain blood samples is correct. Lymphedema can occur due to the disruption of lymphatic vessels during surgery, leading to the accumulation of lymph fluid. To reduce the risk of lymphedema, medical procedures or blood draws should typically avoid using the affected arm. In this case, after a right radical mastectomy, using the left arm for blood samples can help protect the compromised lymphatic system in the right arm.
Choice D Reason:
Obtaining blood pressure readings using the client's right arm is not directly related to preventing lymphedema. However, excessive pressure or trauma to the affected arm should generally be avoided to reduce the risk of lymphedema.
