A client is admitted for recurrent peripheral edema. On admission the patient is AAOX3, lungs are clear to auscultations. Heart rate is 88 bmp, regular rate and rhythm. Respiratory rate is 24 breaths per minute. Abdomen is soft non-tender non-distended, last BM was yesterday and was reported by the patient to be soft, normal brown color. Patient has +2 pitting edema of the bilateral hands and bilateral ankles and feet. Blood pressure is 150/82 mmHg. Pulse ox is 88% on 3 liters of oxygen by nasal cannula. What findings in this assessment require follow-up?

A. Pulse ox of 88% on 3 1pm NC: An oxygen saturation of 88% while receiving 3 liters of oxygen indicates significant impairment in gas exchange. This value is below the standard therapeutic target and suggests worsening pulmonary involvement or ventilation-perfusion mismatch. This finding requires immediate medical evaluation and potential adjustment of respiratory support. B. Lungs are clear to auscultation: This is a normal finding indicating that, at the time of assessment, there is no audible fluid in the alveoli. While heart failure often causes crackles, clear lungs do not require immediate follow-up as an abnormal finding. It serves as a baseline for monitoring future respiratory changes. C. + 2 pitting edema of the bilateral hands: Edema in the upper extremities is an atypical finding for standard dependent edema and suggests severe systemic fluid retention. It indicates that the venous backup has progressed beyond the lower extremities to involve more superior vascular beds. This requires investigation into the underlying cause of generalized anasarca. D. + 2 pitting edema of the ankles and feet: Pitting edema in the lower extremities is a clinical manifestation of systemic venous congestion and fluid volume excess. This finding indicates that the current treatment for peripheral edema is not yet effective. The nurse must monitor this to evaluate the patient's response to diuretic therapy. E. Blood pressure of 150/82: This reading indicates Stage 2 hypertension, which contributes to increased afterload and exacerbates heart failure. Elevated systemic vascular resistance places additional strain on the myocardium and impairs efficient pumping. Persistent hypertension requires pharmacological management to prevent further cardiac remodeling and damage. F. Respiratory rate is 24: A rate of 24 breaths per minute is tachypneic and suggests the patient is compensating for hypoxia or decreased lung compliance. This increased work of breathing often precedes more severe respiratory distress in fluid-overloaded patients. It correlates with the low pulse oximetry and necessitates closer clinical observation. G. Abdomen is soft, non-tender, non-distended: This is a normal physical assessment finding indicating the absence of ascites or organomegaly at this time. It suggests that the fluid volume excess has not yet resulted in significant peritoneal accumulation. No acute nursing or medical follow-up is required for this specific result. H. Client is alert and oriented x 3: Normal mentation indicates that cerebral perfusion is currently adequate despite the patient's low oxygen saturation. It is a positive sign that the patient is not yet experiencing hypercapnia or severe hypoxia-induced encephalopathy. This baseline is used to monitor for any future neurological decline. I. Heart rate is 88 bpm: A heart rate of 88 is within the normal adult range of 60 to 100 beats per minute. This indicates that the heart is not currently in a state of compensatory tachycardia to maintain cardiac output. It is a stable finding that does not require immediate clinical follow-up.
