A woman is diagnosed with primary dysmenorrhea and is prescribed ibuprofen as part of her treatment plan. When teaching the woman about using this medication, which instruction would be important for the nurse to emphasize?

A. "Newborns do not expand their lungs fully with each respiration.": While newborns may have shallow breathing due to immature respiratory muscles, lung expansion does not directly affect the accuracy of respiratory rate measurement.

B. "The rate and rhythm of breath are irregular in newborns.": Newborns commonly exhibit periodic breathing, where the rate and rhythm fluctuate with brief pauses. Counting for a full minute ensures an accurate average respiratory rate and helps detect any abnormal patterns such as apnea.

C. "Newborns are abdominal breathers.": Although newborns primarily use the diaphragm for breathing, resulting in visible abdominal movement, this characteristic does not affect the need to count respirations for a full minute.

D. "Activity will increase the respiratory rate.": While true that crying or movement increases respiration, the nurse counts the rate during quiet rest. The irregular rhythm not activity level is the key reason for measuring over a complete minute.

A. "The severity of future attacks will be much less after using this drug.": Acyclovir can shorten the duration and intensity of current outbreaks but does not guarantee milder future attacks once discontinued. Recurrences depend on viral activity and immune response rather than past treatment alone.

B. "If I use this drug, I will be cured of the infection.": Genital herpes is a lifelong viral infection caused by the herpes simplex virus (HSV). Acyclovir does not cure the disease; it only suppresses viral replication to manage symptoms and reduce outbreak frequency.

C. "This drug will help reduce my risk for a recurrence after discontinuing it.": The benefits of acyclovir are limited to the duration of therapy. Once the medication is stopped, the virus remains dormant in nerve cells and may reactivate, leading to new outbreaks.

D. "This drug will help to suppress any symptoms of the infection.": Acyclovir is an antiviral that helps suppress viral activity, reduce symptom severity, shorten outbreak duration, and decrease viral shedding during active infection.
