A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin?

A. A client who has cellulitis and is receiving oral antibiotics every 8 hr has a mild to moderate infection that can be managed at home with proper wound care and medication adherence. The client does not require hospitalization unless there are signs of systemic infection or complications.

B. A client who is postoperative following an upper endoscopy procedure and is alert but does not have a gag reflex has a high risk of aspiration and airway obstruction due to impaired swallowing function. The client requires close monitoring and intervention until the gag reflex returns, which can take several hours or longer depending on the type and amount of anesthesia used.

C. A mother and their newborn 12 hr postdelivery have not completed the minimum recommended stay of 24 to 48 hours for uncomplicated vaginal deliveries or 72 to 96 hours for cesarean deliveries, according to the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists. The mother and their newborn require assessment, education, support, and follow-up care to ensure their health and well-being.

D. A client who has lower extremity weakness and is newly admitted for observation has an undiagnosed condition that could indicate a serious neurological or vascular problem, such as stroke, spinal cord injury, or peripheral artery disease. The client requires diagnostic testing, evaluation, treatment, and rehabilitation to prevent further deterioration or complications.

A. Pink, frothy sputum is a characteristic finding of pulmonary edema, which is caused by fluid accumulation in the alveoli and interstitial spaces of the lungs. This impairs gas exchange and leads to hypoxia and respiratory distress.

B. Bradycardia is not expected in pulmonary edema. The client is more likely to have tachycardia due to increased sympathetic stimulation and decreased cardiac output.

C. Flushed, dry skin is not expected in pulmonary edema. The client is more likely to have pale, cool, and clammy skin due to peripheral vasoconstriction and decreased perfusion.

D. Wheezing is not a specific finding of pulmonary edema. It may indicate bronchospasm or asthma, which are different conditions that affect the airways rather than the alveoli.
