A nurse is assessing four clients for fluid balance. The nurse should identify that which of the following manifestations of dehydration?
A client who has a urine specific gravity of 1.010. (Reference Range 1.005-1.030)
A client who has a hematocrit of 42%. (Reference Range 36-46%)
A client who has a temperature of 39 °C.
A client who has a weight loss of 2.2 kg in 24 hr.
The Correct Answer is D
Choice A reason: A client who has a urine specific gravity of 1.010 is not dehydrated. Urine specific gravity is a measure of the concentration of solutes in the urine. A normal range is 1.005-1.030, which means that the urine is neither too dilute nor too concentrated. A high urine specific gravity (>1.030) indicates dehydration, as the urine becomes more concentrated due to fluid loss. A low urine specific gravity (<1.005) indicates overhydration, as the urine becomes more dilute due to fluid excess.
Choice B reason: A client who has a hematocrit of 42% is not dehydrated. Hematocrit is the percentage of red blood cells in the blood. A normal range is 36-46% for women and 40-54% for men. A high hematocrit (>54% for men and >46% for women) indicates dehydration, as the blood becomes more viscous due to fluid loss. A low hematocrit (<40% for men and <36% for women) indicates overhydration, as the blood becomes more diluted due to fluid excess.
Choice C reason: A client who has a temperature of 39 °C may or may not be dehydrated. Temperature is a measure of the body's heat production and regulation. A normal range is 36.5-37.5 °C. A high temperature (>37.5 °C) indicates fever, which can be caused by various factors, such as infection, inflammation, or medication. Fever can also cause dehydration, as the body loses fluid through sweating and increased respiration. However, fever is not a specific sign of dehydration, as there may be other causes or contributing factors.
Choice D reason: A client who has a weight loss of 2.2 kg in 24 hr is dehydrated. Weight loss is a measure of the change in the body's mass over time. A normal range is 0.5-1 kg per week. A rapid weight loss (>1 kg per day) indicates dehydration, as the body loses fluid through various routes, such as urine, stool, sweat, or vomit. Weight loss is a sensitive and reliable sign of dehydration, as it reflects the amount of fluid loss.

Correct Answer is C
Explanation
Choice A reason: This is not a correct instruction because drinking a carbonated beverage before bed can worsen the reflux symptoms by increasing the gastric pressure and the production of gas.
Choice B reason: This is not a correct instruction because increasing fatty foods can worsen the reflux symptoms by delaying the gastric emptying and relaxing the lower esophageal sphincter (LES), which allows the stomach acid to flow back into the esophagus.
Choice C reason: This is a correct instruction because elevating the head of the bed when sleeping can help prevent the reflux symptoms by using gravity to keep the stomach contents from flowing back into the esophagus.
Choice D reason: This is not a correct instruction because eating dinner late in the evening can worsen the reflux symptoms by increasing the amount and acidity of the stomach contents, which can easily flow back into the esophagus when lying down. The client should avoid eating within 3 hours of bedtime.
Correct Answer is A
Explanation
Choice A reason: Guarding and rebound tenderness are signs of peritonitis, which is a serious complication of colonoscopy. Peritonitis is an inflammation of the peritoneum, the membrane that lines the abdominal cavity. It can be caused by perforation or puncture of the colon during the colonoscopy, which allows bacteria and fecal matter to enter the peritoneal space. The nurse should monitor the client for signs of peritonitis, such as abdominal pain, rigidity, fever, and leukocytosis.
Choice B reason: Nausea and vomiting are not specific signs of a complication of colonoscopy. They may be caused by other factors, such as the sedation, the bowel preparation, or the ingestion of food or fluids after the procedure. Nausea and vomiting may also be symptoms of other conditions, such as gastroenteritis, food poisoning, or pregnancy.
Choice C reason: Diarrhea is not a sign of a complication of colonoscopy. Diarrhea may be a normal consequence of the bowel preparation, which involves taking laxatives or enemas to clear the colon before the procedure. Diarrhea may also be caused by other factors, such as the ingestion of food or fluids after the procedure, or the presence of an underlying bowel disorder, such as irritable bowel syndrome or inflammatory bowel disease.
Choice D reason: Hyperactive bowel sounds are not a sign of a complication of colonoscopy. Hyperactive bowel sounds may indicate increased peristalsis, which is the movement of the digestive tract. Hyperactive bowel sounds may be a normal response to the bowel preparation, the ingestion of food or fluids after the procedure, or the stimulation of the colon during the colonoscopy. Hyperactive bowel sounds may also be present in conditions such as diarrhea, gastroenteritis, or intestinal obstruction.
