A nurse is to administer a hypotonic solution to a patient with a critically high sodium. Which solution is hypotonic?
0.9% Sodium Chloride
Lactated Ringer's
D5W (5% Dextrose in Water)
0.45% Sodium Chloride
The Correct Answer is D
Choice A reason: This is not a correct answer because 0.9% Sodium Chloride 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.
Choice B reason: This is not a correct answer because Lactated Ringer's 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.
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. However, it is not a preferred solution for a patient with critically high sodium, as it can cause cerebral edema and worsen the neurological status.
Choice D reason: This is a correct answer because 0.45% Sodium Chloride 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 help lower the sodium level and correct the fluid imbalance.

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: Gastritis is not the most likely condition that these clinical manifestations indicate. Gastritis is an inflammation of the stomach lining, which can cause abdominal pain, nausea, vomiting, and loss of appetite. Gastritis may cause heartburn or dyspepsia, but it does not usually cause dysphagia, which is difficulty swallowing.
Choice B reason: GERD is the most likely condition that these clinical manifestations indicate. GERD stands for gastroesophageal reflux disease, which is a chronic condition where the stomach acid flows back into the esophagus, causing irritation and inflammation. GERD can cause heartburn, which is a burning sensation in the chest or throat, dysphagia, which is difficulty swallowing or a feeling of a lump in the throat, and dyspepsia, which is indigestion or discomfort in the upper abdomen.
Choice C reason: Peptic ulcer disease is not the most likely condition that these clinical manifestations indicate. Peptic ulcer disease is a condition where there are open sores or ulcers in the lining of the stomach or duodenum, which can cause bleeding, perforation, or obstruction. Peptic ulcer disease can cause dyspepsia, which is indigestion or discomfort in the upper abdomen, but it does not usually cause heartburn or dysphagia, which are more characteristic of GERD.
Choice D reason: Pancreatitis is not the most likely condition that these clinical manifestations indicate. Pancreatitis is an inflammation of the pancreas, which can cause severe abdominal pain, nausea, vomiting, fever, and jaundice. Pancreatitis does not cause heartburn, dysphagia, or dyspepsia, which are more characteristic of GERD.
