A nurse is teaching a client who is newly diagnosed with type 2 diabetes mellitus about insulin therapy. Which of the following insulin combinations should the nurse instruct the client to mix?

A. Drink 3 L of fluids daily: Increasing fluid intake helps flush bacteria from the urinary tract and dilutes urine, reducing the risk of infection. Adequate hydration also promotes more frequent urination, which prevents bacterial colonization in the bladder.

B. Take a warm bubble bath daily: Bubble baths can introduce irritants and disrupt the normal vaginal flora, increasing the risk of urinary tract infections. Soaking in bathwater containing soap or fragrances can also promote bacterial growth and irritation of the urethra.

C. Drink low-fructose cranberry juice: Cranberry juice contains compounds that help prevent bacteria, particularly Escherichia coli, from adhering to the bladder wall. Low-fructose options are preferred to minimize excessive sugar intake, which can contribute to bacterial growth.

D. Void every 6 hr during the day: Holding urine for long periods allows bacteria to multiply in the bladder, increasing the risk of infection. Voiding every 2 to 4 hours is recommended to promote bladder emptying and reduce bacterial colonization.

E. Wipe the perineal area from front to back after urinating: Wiping from front to back prevents the transfer of bacteria from the anal region to the urethra. This simple hygiene practice helps reduce the risk of E. coli contamination, a leading cause of urinary tract infections.

A. Hypertension: Elevated blood pressure is not a typical sign of bleeding. In cases of significant blood loss, compensatory mechanisms usually lead to hypotension rather than hypertension due to reduced circulating volume. A hypertensive response may occur due to pain or stress but does not indicate hemorrhage.

B. 2+ edema: Postoperative edema can occur from fluid shifts, inflammation, or IV fluid administration but is not a direct indicator of active bleeding. Bleeding is more likely to cause signs of hypovolemia, such as tachycardia or hypotension, rather than localized swelling.

C. Tachycardia: A common early sign of bleeding, as the body compensates for decreased blood volume by increasing heart rate to maintain oxygen delivery. Persistent tachycardia in a postoperative client should raise suspicion for internal bleeding, especially if accompanied by hypotension or pallor.

D. Crackles in lungs: Crackles are usually linked to fluid overload, pneumonia, or heart failure rather than bleeding. Pulmonary congestion may develop after aggressive IV fluid resuscitation, but bleeding primarily manifests with hemodynamic instability rather than respiratory symptoms.
