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

Moist skin

Dark-colored urine

High blood pressure

Distended neck veins

Answer and Explanation

The Correct Answer is B

Choice A reason: Moist skin is not a sign of dehydration, but rather a sign of adequate hydration or sweating. Dehydration can cause dry skin, mucous membranes, and lips.

Choice B reason: Dark-colored urine is a sign of dehydration, as it indicates a high concentration of waste products and a low volume of water in the urine. Dehydration can cause the kidneys to conserve water and produce less urine.

Choice C reason: High blood pressure is not a sign of dehydration, but rather a sign of fluid overload or other factors such as stress, pain, or medication. Dehydration can cause low blood pressure, as it reduces the blood volume and the cardiac output.

Choice D reason: Distended neck veins are not a sign of dehydration, but rather a sign of fluid overload or right-sided heart failure. Dehydration can cause flat neck veins, as it reduces the venous return and the central venous pressure.

Correct Answer is C

Explanation

Choice A reason: This is incorrect because diffusion is the movement of solutes (dissolved substances) from an area of higher concentration to an area of lower concentration, until equilibrium is reached.

Choice B reason: This is incorrect because hydrostatic pressure is the force exerted by a fluid against a wall or a membrane. Hydrostatic pressure can drive the movement of fluid and solutes across a membrane, but it is not the movement itself.

Choice C reason: This is correct because osmosis is the movement of a pure solvent (liquid) across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration, until equilibrium is reached.

Choice D reason: This is incorrect because ATP is not a movement, but a molecule. ATP stands for adenosine triphosphate, which is the main source of energy for cellular processes. ATP can provide energy for some types of transport across membranes, such as active transport.

A. pant with mouth open B. sit up C. lie down D. breathe through a re-breather mask

Correct Answer is B

Explanation

Choice A reason: Panting with mouth open is not an appropriate intervention for an anxious patient with a high respiratory rate. This could increase the risk of hyperventilation and respiratory alkalosis, which could worsen the anxiety and cause symptoms such as dizziness, tingling, and muscle spasms.

Choice B reason: Sitting up is an appropriate intervention for an anxious patient with a high respiratory rate. This could help the patient relax and breathe more deeply and slowly, which could reduce the anxiety and normalize the blood gas levels.

Choice C reason: Lying down is not an appropriate intervention for an anxious patient with a high respiratory rate. This could make the patient feel more claustrophobic and increase the anxiety and the respiratory rate.

Choice D reason: Breathing through a re-breather mask is not an appropriate intervention for an anxious patient with a high respiratory rate. This could increase the oxygen concentration in the blood, which could reduce the stimulus for breathing and cause respiratory depression.
