A nurse is assessing a client who reports numbness and tingling of their toes and exhibits a positive Trousseau's sign. Which of the following electrolyte imbalances should the nurse suspect?

A. Born with a high birth weight: High birth weight is generally not considered a risk factor for hearing loss. In fact, low birth weight, prematurity, or complications during birth are more often associated with an increased risk of hearing issues.

B. Frequent exposure to low-volume noise: Frequent exposure to low-volume noise is not typically a risk factor for hearing loss. However, exposure to loud noises (high volume) over time is a significant risk factor for hearing damage and loss.

C. Use of a loop diuretic: The use of loop diuretics, such as furosemide, is associated with an increased risk of ototoxicity, which can lead to hearing loss. This is a known risk for people taking these medications, especially in high doses or with prolonged use.

D. Chronic infections of the middle ear: Chronic ear infections can lead to hearing loss by damaging the structures of the middle ear or causing scarring. Recurrent middle ear infections, or otitis media, increase the risk of long-term hearing impairment.

E. Perforation of the eardrum: A perforated eardrum can lead to hearing loss, particularly if it affects the middle ear's ability to transmit sound properly. It can also make the ear more susceptible to infections, which could further contribute to hearing loss.

Rationale for Correct Findings:

• Open wound with purulent drainage: A non-healing wound with purulent drainage indicates a possible localized infection. In clients with hyperglycemia or diabetes, wounds are at higher risk for complications, including delayed healing and progression to systemic infection.
• Client reports frequent urination, increased thirst, and recent 4.5 kg (10 lb) weight loss without trying. These are classic symptoms of hyperglycemia and potential new-onset diabetes mellitus which should be further evaluated.
• Client reports experiencing nausea which could be related to hyperglycemia, infection, or other systemic issues.
• Blood glucose 250 mg/dL: This value is significantly elevated and suggests poorly controlled blood glucose levels. Hyperglycemia impairs wound healing, increases infection risk, and can be a sign of undiagnosed or uncontrolled diabetes.
• Temperature 38.3° C (100.9°F): A fever indicates a systemic inflammatory or infectious process. In combination with a draining wound and hyperglycemia, this raises concern for a potential infection requiring medical intervention.
• Blood pressure 98/74 mm Hg: While not critically low, this borderline hypotensive value may reflect early signs of systemic infection or dehydration. It is especially concerning in the context of fever, tachycardia, and possible sepsis.
• Heart rate 104/min: Tachycardia can be a compensatory response to fever, infection, or hypotension. When paired with fever and possible infection, it may indicate early sepsis or systemic involvement and warrants immediate reporting.

Rationale for Incorrect Findings:

• WBC Count 9,500/mm³: This value falls within the normal range and does not alone suggest infection. However, WBC counts may remain normal in some clients with infections, especially those who are immunocompromised or have chronic conditions.
• Respiratory rate 19/min: This is within the normal range and does not independently indicate respiratory distress or systemic compromise at this time.
• Oxygen saturation 97% on room air: Oxygen saturation is adequate and suggests no immediate respiratory compromise. It does not require urgent attention in this scenario.
• Triiodothyronine (T3) 200 mg/dL: This is within the normal range and unrelated to the client’s current presenting issues. Thyroid dysfunction is not suggested by the symptoms or labs at this time.
