A nurse is caring for an adult client who has a fever of 39.4°C (103°F) and is receiving 0.9% sodium chloride IV at 125 mL/hr. Over the last hour, the nurse notes that the client's urine output is 20 mL. The nurse should report this finding to the provider and anticipate a prescription for what?

Choice A reason: This is not the best response because it does not accurately describe the client's condition. Obstruction is a possible complication of diverticulitis, but it is not indicated by fever and abdominal rigidity. Obstruction is more likely to cause symptoms such as nausea, vomiting, constipation, and abdominal distension.

Choice B reason: This is not the best response because it can worsen the client's condition. Positioning the client supine and inserting an NG tube are interventions for gastric outlet obstruction, not diverticulitis. An NG tube can increase the risk of infection and perforation in the inflamed colon. Supine position can also increase the pressure on the abdomen and cause more pain and discomfort.

Choice C reason: This is not the best response because it can be harmful to the client. Administering a fleet enema is contraindicated for diverticulitis, as it can cause more inflammation, bleeding, or perforation in the colon. A fleet enema is a type of laxative that contains sodium phosphate and is used to relieve constipation or prepare for colonoscopy.

Choice D reason: This is the best response because it is the most appropriate and urgent action for the client. Contacting the primary provider promptly and reporting these signs of perforation is essential for the client's safety and treatment. Perforation is a life-threatening complication of diverticulitis, where the colon wall ruptures and causes peritonitis, which is inflammation of the abdominal cavity. Perforation can cause symptoms such as fever, abdominal rigidity, tenderness, and rebound pain. Perforation requires immediate surgical intervention and antibiotic therapy.

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.
