A nurse is assessing four clients for fluid balance. The nurse should identify that which of the following manifestations of dehydration?
A. A client who has a urine specific gravity of 1.010. (Reference Range 1.005-1.030)
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.
B. A client who has a hematocrit of 42%. (Reference Range 36-46%)
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.
C. A client who has a temperature of 39 °C.
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.
D. A client who has a weight loss of 2.2 kg in 24 hr.
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.

Full Explanation
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.

A nurse is admitting a client with suspected appendicitis. Identify where the nurse will palpate to assess for pain at McBurney's point. (Selectable areas, or "Hot Spots," are outlined in the artwork below. Select only the outlined area that corresponds to your answer)
A. Upper right quadrant
The upper right quadrant is not the correct location for McBurney's point. This quadrant contains the liver, gallbladder, right kidney, and part of the colon. Pain in this area may indicate problems with these organs, such as hepatitis, gallstones, or kidney infection.
B. Upper left quadrant
The upper left quadrant is not the correct location for McBurney's point. This quadrant contains the stomach, spleen, left kidney, and part of the colon. Pain in this area may indicate problems with these organs, such as gastritis, splenomegaly, or kidney stones.
C. Lower right quadrant
The lower right quadrant is the correct location for McBurney's point. This quadrant contains the appendix, right ovary, and right fallopian tube. McBurney's point is a point on the abdomen that is one-third of the distance from the right anterior superior iliac spine to the umbilicus. Pain in this area may indicate appendicitis, ovarian cyst, or ectopic pregnancy.
D. Lower left quadrant
The lower left quadrant is not the correct location for McBurney's point. This quadrant contains the sigmoid colon, left ovary, and left fallopian tube. Pain in this area may indicate problems with these organs, such as diverticulitis, ovarian torsion, or pelvic inflammatory disease.

A nurse is discussing safety for administering intravenous fluids. Which condition might occur if hypertonic solutions are administered too quickly?
A. Mental alertness
Mental alertness is not affected by the administration of hypertonic solutions. Hypertonic solutions are fluids that have a higher concentration of solutes than the blood. They draw water out of the cells and into the blood vessels, increasing the blood volume and osmolarity.
B. Decreased pulse
Decreased pulse is not a result of administering hypertonic solutions too quickly. On the contrary, hypertonic solutions can increase the pulse rate as they increase the blood volume and pressure.
C. Decreased blood pressure
Decreased blood pressure is not a consequence of administering hypertonic solutions too quickly. Hypertonic solutions can raise the blood pressure as they increase the blood volume and osmolarity.
D. Fluid overload
Fluid overload is the correct answer. Administering hypertonic solutions too quickly can cause fluid overload, which is a condition where the body has too much fluid in the blood vessels. This can lead to symptoms such as edema, dyspnea, crackles, and weight gain. Fluid overload can also cause heart failure, pulmonary edema, and cerebral edema.

The community health nurse is performing a home visit for a 74-year-old client recovering from hip surgery. The nurse notes that the client seems uncharacteristically confused at times and has dry mucous membranes. The client states to stop drinking water early in the day because it's just too difficult to get up during the night to go to the bathroom. What would be the nurse's best response?
A. You need to have your medications adjusted so you need to be admitted to the hospital for a complete workup.
This is not the best response because it is alarmist and does not address the client's concern. The nurse should not assume that the client needs to have their medications adjusted or be admitted to the hospital without further assessment.
B. You build up too much urine in your bladder, which can cause you to get confused.
This is not the best response because it is inaccurate and does not explain the link between urine retention and confusion. The nurse should not imply that the client is causing their own confusion by not drinking enough water.
C. Dehydration can cause changes that can result in confusion, so let's try to increase your fluid intake.
This is the best response because it is accurate and educates the client on the effects of dehydration on the body. The nurse should encourage the client to drink more fluids throughout the day and offer strategies to make it easier for them to access the bathroom at night.
D. Urinary tract infections are common and can cause confusion, so it's important not to urinate at night.
This is not the best response because it is irrelevant and does not address the client's dehydration. The nurse should not suggest that the client has a urinary tract infection without evidence or testing. The nurse should also not discourage the client from urinating at night, as this can lead to other complications.
