The nurse hears crackles when auscultating a client's lung sounds. Which is an accurate description of the sound of crackles?

A. "I cough a lot at night and it keeps me up half the night." Night-time coughing can be associated with various conditions, including asthma, GERD, or postnasal drip, but it is not specifically indicative of orthopnoea.

B. "I sleep on three pillows at night." This supports orthopnoea, which is difficulty breathing when lying flat. Clients with orthopnoea often use multiple pillows to elevate their upper body to alleviate shortness of breath.

C. "I have multiple attacks of wheezing almost daily." Frequent wheezing is more indicative of asthma or other obstructive airway diseases, not orthopnoea.

D. "It doesn't take much activity before I'm out of breath." This describes dyspnoea on exertion, which is different from orthopnoea, as it refers to difficulty breathing during physical activity rather than when lying down.

A. Multiple maculopapular pustules over forehead and chin on an adolescent student: These pustules could be indicative of an infectious process, such as acne or impetigo. While not necessarily an emergency, it’s important to assess and potentially treat these skin lesions promptly. The school nurse should report this to the healthcare provider for further evaluation.

B. Red, swollen, painful nodule located on the upper back of a school-aged student: This finding raises concern for an abscess or localized infection. The pain, redness, and swelling suggest an inflammatory process. The nurse should promptly report this to the healthcare provider for assessment and appropriate management.

C. Small, white flecks on the hair shafts throughout the scalp on a school-aged child: These white flecks are likely nits (lice eggs). While not an emergency, they do require attention. The nurse should inform the parents or guardians and recommend appropriate treatment. However, this finding does not necessitate immediate reporting to the healthcare provider.

D. Bilateral patellar abrasions with eschar formation on a preschool-aged student: Abrasions with eschar (dead tissue) formation can indicate a deeper injury. The nurse should report this to the healthcare provider promptly for assessment and wound care recommendations.
