A client with myasthenia gravis receives a new prescription for pyridostigmine. Which information should the nurse obtain prior to administering the medication?

Choice A reason: Storing unused vials at room temperature is incorrect information that indicates a need for further education by the nurse, because somatropin is a growth hormone that should be stored in the refrigerator (2°C to 8°C) until use. Exposure to heat or light can degrade the medication and reduce its effectiveness.

Choice B reason: Rotating injection sites to minimize discomfort is correct information that does not indicate a need for further education by the nurse, because somatropin is administered subcutaneously and repeated injections at the same site can cause skin irritation, bruising, or infection.

Choice C reason: Discarding the medication if the solution is cloudy is correct information that does not indicate a need for further education by the nurse, because somatropin is a clear and colorless solution that should not be used if it appears cloudy, discolored, or contains particles. This may indicate contamination or degradation of the medication.

Choice D reason: Administering the medication subcutaneously is correct information that does not indicate a need for further education by the nurse, because somatropin is a growth hormone that is given by subcutaneous injection using a syringe or a pen device. Subcutaneous injection allows for better absorption and bioavailability of the medication.

Choice A reason: Promoting stomach emptying and preventing gastric reflux is not a relevant action of sevelamer, which is a phosphate binder that lowers serum phosphate levels in patients with CKD. Gastric reflux may be caused by other factors, such as hiatal hernia, obesity, or spicy foods.

Choice B reason: Buffering hydrochloric acid and preventing gastric erosion is not a pertinent action of sevelamer, which does not affect gastric acidity or mucosal integrity. Gastric erosion may be caused by other factors, such as NSAIDs, alcohol, or Helicobacter pylori infection.

Choice C reason: Preventing indigestion associated with ingestion of spicy foods is not a significant action of sevelamer, which does not affect digestion or food tolerance. Indigestion may be caused by other factors, such as overeating, stress, or gallstones.

Choice D reason: Binding with phosphorus in foods and preventing absorption is the correct action of sevelamer, which should be taken with meals to reduce the amount of phosphorus that enters the bloodstream from the diet. High serum phosphate levels can cause bone loss, calcification of soft tissues, and secondary hyperparathyroidism in patients with CKD.
