A nurse is caring for a client who has cholecystitis with cholelithiasis and obstruction of the common bile duct. The nurse should expect the client's urine to appear which of the following colors?

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.

Choice A reason: Normal saline is not contraindicated for a dehydrated client with a skull fracture. Normal saline is an isotonic solution that has the same concentration of solutes as the blood plasma. It can help restore fluid balance and prevent cerebral edema.

Choice B reason: Dextrose in water 5% is contraindicated for a dehydrated client with a skull fracture. Dextrose in water 5% is a hypotonic solution that has a lower concentration of solutes than the blood plasma. It can cause fluid to shift from the blood vessels into the brain cells, increasing the intracranial pressure and worsening the skull fracture.

Choice C reason: Lactated Ringer's (LR) is not contraindicated for a dehydrated client with a skull fracture. Lactated Ringer's (LR) is an isotonic solution that has the same concentration of solutes as the blood plasma. It can also provide electrolytes such as sodium, potassium, calcium, and lactate, which can help correct acid-base imbalances.

Choice D reason: Dextrose in normal saline is not contraindicated for a dehydrated client with a skull fracture. Dextrose in normal saline is a hypertonic solution that has a higher concentration of solutes than the blood plasma. It can cause fluid to shift from the brain cells into the blood vessels, reducing the intracranial pressure and cerebral edema.
