A nurse is preparing to administer labetalol 40 mg IV to a client. Available is labetalol 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Rationale:

A. "You should expect your blisters to last up to three weeks.": Herpes zoster lesions typically last 7 to 10 days, with crusting and healing often occurring within 2 weeks. While some cases may extend slightly longer, stating "up to three weeks" may overgeneralize and mislead.

B. "Antiviral medications are most effective if taken within the first 72 hours of symptoms.": Antiviral drugs like acyclovir or valacyclovir are most effective when initiated within 72 hours of symptom onset. Early treatment reduces severity, duration, and the risk of complications such as postherpetic neuralgia.

C. "People who have had chicken pox are at a decreased risk for herpes zoster.": Herpes zoster occurs due to reactivation of the varicella-zoster virus, which remains dormant after chickenpox. Therefore, individuals who have had chickenpox are actually at increased risk.

D. "Severe pain after the blisters are gone is less common in older adults.": Older adults are more likely to experience postherpetic neuralgia, a complication involving persistent nerve pain after lesions resolve. The risk and severity of this pain increase with age, not decrease.

Rationale:

A. "Attempt to void every 2 hours.": Scheduled voiding helps reduce the likelihood of bladder overfilling and decreases episodes of leakage, especially in stress incontinence where physical pressure causes urine loss.

B. "Perform Kegel exercises several times daily.": Kegel exercises strengthen the pelvic floor muscles, which support the bladder and urethra. Regular practice improves muscle tone and helps control urine leakage during activities like coughing or sneezing.

C. "Maintain a daily fluid intake of 1,000 to 1,200 mL/day.": Limiting fluids excessively can lead to concentrated urine and bladder irritation, increasing urgency and risk of infection. A moderate, well-balanced intake closer to 1,500–2,000 mL/day is generally recommended.

D. "Take prescribed diuretics no later than 2000.": While relevant for fluid management, it's not a direct or primary instruction specifically for treating or managing stress incontinence itself. Diuretics increase urine production, which could potentially worsen incontinence.

E. "Maintain optimal body weight for height.": Excess weight increases abdominal pressure on the bladder, worsening stress incontinence. Achieving and maintaining a healthy weight can reduce symptoms and support pelvic muscle strength.
