The nurse is preparing to hang the client's next bag of Total Parenteral Nutrition (TPN) and observes fat globules rising to the top of the solution. What action should the nurse take?
Run the bag under warm water to melt the globules.
Call the pharmacy to get a new bag of TPN.
Do nothing, as fat globules are expected to rise to the top of the TPN solution.
Roll the bag of solution gently to redistribute the fat.
The Correct Answer is B
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.

Correct Answer is D
Explanation
Choice A reason:
While polyhydramnios can be associated with congenital anomalies or fetal distress, it is not a direct indication of these conditions. Polyhydramnios refers specifically to the excessive accumulation of amniotic fluid. Congenital anomalies may lead to polyhydramnios if they affect the fetus's ability to swallow and process amniotic fluid normally, but the presence of polyhydramnios alone does not confirm these conditions.
Choice B reason:
Elevated levels of alpha-fetoprotein (AFP) in the amniotic fluid can be indicative of neural tube defects or other fetal abnormalities, but they are not a defining characteristic of polyhydramnios. Normal AFP levels in amniotic fluid at 15 to 21 weeks' gestation range from 10 to 150 ng/ml. Polyhydramnios is diagnosed based on the volume of amniotic fluid, not the AFP levels.
Choice C reason:
Carrying more than one fetus can lead to an increased amount of amniotic fluid, potentially resulting in polyhydramnios. However, the diagnosis of polyhydramnios itself does not imply a multiple gestation pregnancy. It simply indicates that there is more amniotic fluid than usual.
Choice D reason:
Polyhydramnios is defined as an excessive amount of amniotic fluid. It is typically diagnosed when the amniotic fluid index (AFI) exceeds 24 cm or the single deepest pocket (SDP) measures more than 8 cm. This condition can occur due to various reasons, including fetal anomalies, maternal diabetes, and other medical conditions.
Correct Answer is B
Explanation
Choice A reason:
Performing a 12-lead electrocardiogram and calling a rapid response team are important steps when a pulmonary embolism is suspected. However, these actions are not the immediate first-line interventions. The priority is to address the client's oxygenation needs to prevent further hypoxemia and potential cardiac arrest.
Choice B reason:
Elevating the head of the bed and applying 2 liters of nasal oxygen is the most appropriate initial intervention. This position helps improve the expansion of the lungs and oxygenation, while the supplemental oxygen can help alleviate hypoxemia, which is critical in the management of a pulmonary embolism.
Choice C reason:
While ensuring the client remains calm is beneficial, administering lorazepam is not the first-line treatment for a suspected pulmonary embolism. Lorazepam may be used for its anxiolytic effects, but it does not address the immediate life-threatening issues of oxygenation and potential hemodynamic instability.
Choice D reason:
Increasing the intravenous rate may be considered to maintain adequate hydration and venous return, but it is not the first intervention for a suspected pulmonary embolism. The priority is to stabilize the client's respiratory status and oxygenation.
