The patient who was admitted after vomiting for 3 days would show an abnormally low blood pressure because of a fluid shift from:

intracellular to the extracellular.

interstitial to intravascular.

interstitial to the intracellular.

intravascular to the interstitial.

Answer and Explanation

The Correct Answer is D

Choice A reason: Intracellular to the extracellular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the cells lose water due to osmosis, such as in dehydration or hypernatremia.

Choice B reason: Interstitial to intravascular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the tissue spaces to the blood vessels, such as in hypovolemia or hypotonic fluid administration.

Choice C reason: Interstitial to the intracellular fluid shift is not the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the tissue spaces to the cells, such as in overhydration or hyponatremia.

Choice D reason: Intravascular to the interstitial fluid shift is the cause of low blood pressure in this case. This fluid shift occurs when the fluid moves from the blood vessels to the tissue spaces, such as in edema, inflammation, or increased capillary permeability. This reduces the blood volume and lowers the blood pressure.

Correct Answer is A

Explanation

Choice A reason: The client with an ileostomy is at risk for fluid volume deficit because an ileostomy is a surgical opening in the ileum, the last part of the small intestine, that allows the drainage of intestinal contents. This can result in a loss of fluids and electrolytes, especially sodium and potassium, which can lead to dehydration and hypovolemia.

Choice B reason: The client with cirrhosis is not at risk for fluid volume deficit, but rather fluid volume excess. Cirrhosis is a chronic liver disease that causes scarring and impaired liver function. This can lead to portal hypertension, which is an increase in the pressure in the portal vein that carries blood from the digestive organs to the liver. Portal hypertension can cause ascites, which is the accumulation of fluid in the abdominal cavity, and edema, which is the swelling of the tissues due to fluid retention.

Choice C reason: The client with heart failure is not at risk for fluid volume deficit, but rather fluid volume excess. Heart failure is a condition where the heart is unable to pump enough blood to meet the body's needs. This can lead to congestion of the blood vessels, which can cause pulmonary edema, which is the accumulation of fluid in the lungs, and peripheral edema, which is the swelling of the extremities due to fluid retention.

Choice D reason: The client with decreased renal function is not at risk for fluid volume deficit, but rather fluid volume excess. Decreased renal function is a condition where the kidneys are unable to filter the blood and remove excess fluids and wastes. This can lead to oliguria, which is a decrease in urine output, and anuria, which is the absence of urine output. This can cause fluid overload, which can affect the heart and the lungs.

A. Filtration B. Active transport C. Diffusion D. Osmosis

Correct Answer is B

Explanation

Choice A reason: This is incorrect because filtration is a passive transport mechanism that does not require cellular energy. Filtration is the movement of fluid and solutes across a membrane due to hydrostatic pressure.

Choice B reason: This is correct because active transport is a transport mechanism that requires cellular energy in the form of ATP. Active transport is the movement of molecules across a membrane against their concentration gradient, using carrier proteins.

Choice C reason: This is incorrect because diffusion is a passive transport mechanism that does not require cellular energy. Diffusion is the movement of molecules from an area of higher concentration to an area of lower concentration, until equilibrium is reached.

Choice D reason: This is incorrect because osmosis is a passive transport mechanism that does not require cellular energy. Osmosis is the movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

The nurse is reviewing the health records of assigned clients. The nurse would plan care knowing that which client is at risk for fluid volume deficit?

Correct Answer is A

Explanation

Which transport mechanism involves cellular energy?

Correct Answer is B

Explanation

George Torres is admitted with a head injury. He is comatose and is breathing rapidly. His blood gases show a pH of 7.47, PaCO2 of 32 mm Hg, and HCO3- of 26 mEq/L. Compare these gases to normal values. What type of imbalance does this patient have, and is it being compensated or uncompensated?

The nurse points out that electrolytes are essential for health. Nonelectrolytes include:

The nurse is aware that small ions such as glucose, oxygen, and carbon dioxide redistribute themselves through semipermeable membranes by a process called dropdown.

Which fluid output measurement is the most concerning for a nurse?

Which may cause hyperkalemia?

A nurse is collecting data from a patient who has dehydration. Which of the following findings should the nurse expect?

The nurse observed that a client with diabetic ketoacidosis is experiencing abnormally deep, regular, and rapid respirations. How would the nurse document this observation in the medical record?

An anxious adult patient is experiencing a respiratory rate of 40 breaths/min. The most appropriate intervention that the nurse could do is to instruct the patient to:
