A nurse formulates the problem of ineffective airway clearance for a client who has pneumonia. Which assessment data best supports this problem?

Choice A Reason
Running the bag under warm water to melt the globules is not recommended. Applying heat could compromise the sterility and integrity of the solution. TPN solutions are carefully balanced and sterile, and any manipulation involving temperature changes could lead to contamination or nutrient degradation.

Choice B Reason
Observing fat globules at the top of the TPN solution is a sign that the emulsion may be compromised. The nurse should not administer this TPN solution and should call the pharmacy for a replacement. TPN solutions should be homogenous with no visible separation or fat globules to ensure the patient receives the correct nutrition and to prevent complications.

Choice C Reason
Doing nothing is not an appropriate action. Fat globules indicate that the solution has separated, which can lead to an unstable emulsion and potential harm if infused. The nurse's responsibility is to ensure the safety and efficacy of the treatment, which includes verifying that TPN solutions are properly mixed.

Choice D Reason
Rolling the bag gently to redistribute the fat is not a safe practice. While gentle agitation can be used for some medications, it is not appropriate for TPN solutions with visible fat globules. This could further destabilize the emulsion and does not address the underlying issue of separation.

Choice A reason:
Cyanosis, or a bluish discoloration of the skin, particularly in the nail beds, is a sign of inadequate oxygenation and would not indicate successful intervention. The absence of cyanosis would be a positive outcome, reflecting improved oxygen saturation.

Choice B reason:
Lungs clear to auscultation would indicate that air is moving through all regions of the lungs without obstruction from fluid or mucus, which is a sign of recovery from pneumonia. This finding suggests that the interventions aimed at improving gas exchange, such as positioning, deep breathing exercises, and suctioning if needed, have been effective.

Choice C reason: The inability to speak in full sentences often indicates respiratory distress and would not be a sign of successful nursing intervention. An improvement would be the client's ability to speak in full sentences without difficulty, reflecting better lung function and gas exchange.

Choice D reason:
Pulse oximetry readings between 94-96% on room air are within normal limits and indicate adequate oxygen saturation and gas exchange. This is a clear sign that the client's respiratory status has improved, and the interventions for Impaired Gas Exchange have been successful.

Choice E reason:
Bronchovesicular breath sounds are normal breath sounds heard over the major bronchi and are typically moderate in pitch and intensity. However, they are not specifically indicative of successful intervention for Impaired Gas Exchange. The absence of abnormal sounds such as crackles or wheezes would be more relevant.
