Which transport mechanism involves cellular energy?

Filtration

Active transport

Diffusion

Osmosis

Answer and Explanation

The Correct Answer is B

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.

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.

A. Potential for over-hydration related to excessive thirst B. Potential for diarrhea related to dehydration C. Potential for pulmonary congestion related to excessive fluid intake D. Potential for fall related to confusion

Correct Answer is D

Explanation

Choice A reason: This is incorrect because over-hydration is unlikely in a dehydrated patient. Over-hydration is a condition where the body has too much water, which can cause hyponatremia, edema, and cerebral swelling.

Choice B reason: This is incorrect because diarrhea is a cause, not a consequence, of dehydration. Diarrhea is the frequent and watery passage of stool, which can lead to fluid and electrolyte loss.

Choice C reason: This is incorrect because pulmonary congestion is also unlikely in a dehydrated patient. Pulmonary congestion is a condition where the lungs are filled with fluid, which can cause dyspnea, cough, and crackles.

Choice D reason: This is correct because fall is a potential complication of dehydration. Dehydration can cause confusion, dizziness, weakness, and hypotension, which can increase the risk of falling and injuring oneself.
