A nurse is caring for several patients with fluid imbalances. A priority nursing intervention for a client with hypervolemia involves which of the following?

Choice A reason: Reintroducing foods that intensify symptoms one at a time is not an intervention that the nurse would recommend for a client with GERD. Foods that can trigger or worsen GERD symptoms include spicy, acidic, fatty, or fried foods, chocolate, coffee, alcohol, mint, garlic, and onion. The nurse would advise the client to avoid or limit these foods, not to reintroduce them.

Choice B reason: Promoting intake of food and fluids 1 to 2 hours before bedtime is not an intervention that the nurse would recommend for a client with GERD. Eating or drinking close to bedtime can increase the risk of acid reflux, as the stomach contents can flow back into the esophagus when the client lies down. The nurse would suggest the client to have smaller and more frequent meals, and to avoid eating or drinking at least 3 hours before bedtime.

Choice C reason: Maintaining an upright position following meals is an intervention that the nurse would recommend for a client with GERD. Keeping an upright posture can help prevent or reduce acid reflux, as gravity can help keep the stomach contents in place. The nurse would encourage the client to avoid bending, stooping, or lying down for at least 2 hours after eating.

Choice D reason: Increasing the amount of carbonated beverages is not an intervention that the nurse would recommend for a client with GERD. Carbonated beverages can increase the production of gas and stomach acid, which can cause bloating, belching, and acid reflux. The nurse would advise the client to drink water or other non-carbonated fluids, and to avoid drinking through a straw or chewing gum, which can also introduce air into the stomach.

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.
