A nurse is discussing safety for administering intravenous fluids. Which condition might occur if hypertonic solutions are administered too quickly?

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: Dark-colored stools are an adverse effect of orlistat, a medication that blocks the absorption of fat in the intestines. The unabsorbed fat can cause the stools to become oily, foul-smelling, and dark in color. This can indicate a serious condition called steatorrhea, which can lead to malnutrition and vitamin deficiencies.

Choice B reason: Constipation is not an adverse effect of orlistat. In fact, orlistat can cause the opposite problem of diarrhea, especially if the client consumes too much fat in their diet. Constipation may be caused by other factors, such as dehydration, lack of fiber, or medication side effects.

Choice C reason: Nausea is not an adverse effect of orlistat. Nausea may be a symptom of other conditions, such as gastritis, gastroenteritis, or pregnancy. Nausea may also be caused by other medications, such as antibiotics, opioids, or chemotherapy drugs.

Choice D reason: Abdominal pain is not an adverse effect of orlistat. Abdominal pain may be a sign of other conditions, such as appendicitis, gallstones, or kidney stones. Abdominal pain may also be caused by other medications, such as NSAIDs, steroids, or oral contraceptives.
