A severely dehydrated client has come in for rapid administration of IV fluids. Which of the following solutions is the best solution for rapid infusion?
Normal Saline
1/2 Normal Saline
D5W (5% Dextrose in Water)
D5 1/2 Normal Saline
The Correct Answer is A
Choice A reason: This is a correct answer because normal saline is an isotonic solution, which means it has the same osmolarity as the blood plasma. It does not cause any fluid shifts between the intracellular and extracellular compartments, and it can help restore the fluid balance and the blood pressure of the dehydrated client.
Choice B reason: This is not a correct answer because 1/2 normal saline is a hypotonic solution, which means it has a lower osmolarity than the blood plasma. It causes fluid to shift from the extracellular to the intracellular compartment, which can lead to cellular swelling and edema. It is not suitable for rapid infusion, as it can cause hemolysis and hypotension.
Choice C reason: This is not a correct answer because D5W (5% Dextrose in Water) is an isotonic solution when it is in the IV bag, but it becomes hypotonic once it enters the body, as the dextrose is rapidly metabolized and only water remains. It causes fluid to shift from the extracellular to the intracellular compartment, which can lead to cellular swelling and edema. It is not suitable for rapid infusion, as it can cause hemolysis and hypotension.
Choice D reason: This is not a correct answer because D5 1/2 normal saline is a hypertonic solution, which means it has a higher osmolarity than the blood plasma. It causes fluid to shift from the intracellular to the extracellular compartment, which can lead to cellular shrinkage and dehydration. It is not suitable for rapid infusion, as it can cause hypernatremia and fluid overload.

Correct Answer is B
Explanation
Choice A reason: MRI is not a diagnostic procedure for Barrett esophagus. MRI is a type of imaging test that uses magnetic fields and radio waves to create detailed pictures of the internal organs and tissues. It is mainly used to diagnose problems in the brain, spine, joints, and blood vessels.
Choice B reason: EGD is a diagnostic procedure for Barrett esophagus. EGD is a type of endoscopy that uses a flexible tube with a light and a camera to examine the esophagus, stomach, and duodenum. It can detect changes in the lining of the esophagus that may indicate Barrett esophagus, a condition where the normal squamous cells are replaced by columnar cells due to chronic acid exposure.
Choice C reason: Colonoscopy is not a diagnostic procedure for Barrett esophagus. Colonoscopy is a type of endoscopy that uses a flexible tube with a light and a camera to examine the colon and rectum. It is mainly used to screen for colorectal cancer and polyps, as well as to diagnose inflammatory bowel disease and other conditions affecting the lower gastrointestinal tract.
Choice D reason: CT scan is not a diagnostic procedure for Barrett esophagus. CT scan is a type of imaging test that uses X-rays and a computer to create cross-sectional pictures of the body. It is mainly used to diagnose problems in the chest, abdomen, pelvis, and bones.
Correct Answer is B
Explanation
Choice A reason: Calling the doctor for more antiemetic medication is not the best intervention for the nurse to facilitate. Antiemetics are drugs that prevent or reduce nausea and vomiting, but they may have side effects such as drowsiness, dry mouth, or constipation. The nurse should first try non-pharmacological measures to relieve the patient's nausea, such as giving small sips of water, providing a cool and quiet environment, or using aromatherapy.
Choice B reason: Giving the patient small sips of tepid water is the best intervention for the nurse to facilitate. Water can help hydrate the patient and dilute any stomach acid that may cause irritation. Tepid water is water that is slightly warm, which can be more soothing than cold or hot water. Small sips can prevent the patient from swallowing too much air, which can worsen nausea and vomiting.
Choice C reason: Helping the patient lay supine is not a good intervention for the nurse to facilitate. Supine means lying flat on the back, which can increase the risk of aspiration, or inhaling food or fluids into the lungs. Aspiration can cause pneumonia, a serious lung infection. The nurse should help the patient lay on their side, with their head elevated, to prevent aspiration and reduce pressure on the stomach.
Choice D reason: Showing the patient how to use the patient-controlled analgesia is not a relevant intervention for the nurse to facilitate. Patient-controlled analgesia is a system that allows the patient to self-administer pain medication through an IV pump. It has nothing to do with nausea and vomiting, and may even cause them as side effects. The nurse should monitor the patient's pain level and adjust the analgesia settings as needed, but not as a way to treat nausea.
