A nurse is teaching a class about using niacin to reduce LDL cholesterol.
The nurse should include in the teaching that which of the following conditions is a contraindication for receiving this medication?

Choice A rationale:

Keeping a can of concentrated formula in the refrigerator for 3 days after opening it is not safe. Once a can of formula is opened, it should be used within 24 hours and stored in the refrigerator. After 24 hours, any leftover formula should be discarded to prevent the risk of bacterial contamination.

Choice B rationale:

Diluting ready-to-feed formula with water is incorrect. Ready-to-feed formula is already prepared and does not need to be diluted further. Adding water to ready-to-feed formula can dilute its nutritional content and may not provide the necessary nutrients for the baby.

Choice C rationale:

Boiling tap water for 2 minutes and cooling it before mixing it with powdered formula is the correct method for safe formula preparation. Boiling the water kills harmful bacteria and ensures the formula is safe for the baby to consume. It is essential to cool the boiled water before mixing it with powdered formula to reach an appropriate feeding temperature.

Choice D rationale:

Ensuring that all bottles contain BPA (bisphenol A) is not a relevant consideration for formula preparation. BPA is a chemical that was previously used in some plastics, including baby bottles, but has been banned in baby bottles and sippy cups in several countries due to its potential health risks. Most modern baby bottles are BPA-free, and this statement does not address the safe handling and preparation of formula for the baby.

Choice A rationale:

The nurse should ensure that the side rails are up on the client's bed. This action is essential for the safety of the client with severe preeclampsia, as it prevents accidental falls or injuries. Preeclampsia is a hypertensive disorder of pregnancy characterized by high blood pressure and signs of organ damage, and it poses significant risks to both the mother and the fetus. By keeping the side rails up, the nurse can minimize the risk of falls and ensure the client's safety while in bed.

Choice B rationale:

Ambulating the client every 4 hours is not appropriate for a pregnant woman with severe preeclampsia. Preeclampsia can cause high blood pressure, swelling, and proteinuria. It is a serious condition that requires close monitoring and strict bed rest to prevent complications such as seizures or eclampsia. Ambulation may increase the risk of falls and is contraindicated in this situation.

Choice C rationale:

Checking the fetal heart rate twice daily is important in the care of a pregnant client with severe preeclampsia. However, ensuring the client's safety by keeping the side rails up on the bed takes priority. While monitoring the fetal heart rate is crucial for assessing the baby's well-being, it does not address the immediate safety concerns of the client, which can be addressed by maintaining the side rails up.

Choice D rationale:

Providing the client with a low-protein diet is not the correct action for a pregnant woman with severe preeclampsia. In fact, pregnant women with preeclampsia are often advised to increase their protein intake to help manage their condition. A low-protein diet can lead to malnutrition and may not provide the necessary nutrients for both the mother and the developing fetus. The primary focus should be on bed rest, monitoring vital signs, and managing symptoms to prevent complications.
