A nurse is reviewing the medical record of a client who has developed a UTI. Which of the following findings should the nurse expect?

Choice A rationale:

Crackles are adventitious lung sounds that can be heard on auscultation and are commonly associated with pneumonia. They are caused by the movement of air through fluid-filled or collapsed alveoli, indicating inflammation and infection in the lungs.

Choice B rationale:

Crepitus is a different respiratory finding and is not typically associated with pneumonia. Crepitus is a crackling or grating sensation that can be felt under the skin, often caused by subcutaneous emphysema or gas trapped in the tissues, not within the lungs.

Choice C rationale:

Stridor is a harsh, high-pitched sound heard during inspiration and is usually indicative of upper airway obstruction, not pneumonia. It can be caused by conditions such as croup or anaphylaxis.

Choice D rationale:

Decreased fremitus is not a specific manifestation of pneumonia. Fremitus is the vibration felt when the patient speaks and is transmitted through the chest wall. In pneumonia, increased fremitus may be observed due to the consolidation of lung tissue with fluid or pus, not decreased fremitus.

Choice A rationale:
An INR (International Normalized Ratio) of 0.8 is within the normal range for someone not on anticoagulation therapy. The aPTT (activated partial thromboplastin time) of 85 seconds is prolonged, but it is not a reason to withhold heparin in itself. Therefore, the nurse should not withhold the medication for these values.
Choice B rationale:
An INR of 2 indicates the client's blood is taking twice as long to clot compared to the average, which can increase the risk of bleeding. The aPTT of 60 seconds is within the normal range. However, the elevated INR suggests the client might be overly anticoagulated, so the nurse should withhold the medication and notify the provider.
