A nurse is assisting with teaching a newly licensed nurse about the loss of body heat. The nurse should include that heat loss that occurs when sweat dries on the skin is caused by which of the following mechanisms?

Convection

Evaporation

Conduction

Radiation

Answer and Explanation

The Correct Answer is B

A: Convection involves the movement of air or liquid around the body, which then carries heat away but does not involve phase change like evaporation.
B: Evaporation is the process where liquid (sweat) turns into vapor, removing heat from the surface it evaporates from, which is the primary cooling mechanism in sweating.
C: Conduction involves direct transfer of heat through contact with cooler objects, not relevant to the drying of sweat.
D: Radiation refers to heat transfer through electromagnetic waves and does not require the presence of an intervening medium, unlike the evaporation of sweat.

Correct Answer is B

Explanation

A: Subjective information refers to what the patient experiences and reports, not what is sensed by the observer.
B: Objective signs are those that can be observed and measured by someone other than the patient, such as visual inspections, palpations, and auditory cues.
C: Reported by the patient would be subjective data, opposite of what is sensed and recorded by healthcare providers.
D: Hidden signs would imply they are not readily observable, which contradicts the use of senses to identify them.

A. Request assistance from a second nurse. B. Count the client's apical pulse. C. Check the client's pulse rate for 1 min. D. Calculate the difference between the client's peripheral pulse and the client's apical pulse.

Correct Answer is A

Explanation

A: To accurately determine a pulse deficit, one nurse must listen to the apical pulse while another nurse palpates the radial pulse simultaneously to compare both pulse rates, necessitating a second person.
B: Counting the apical pulse is a part of the process but would follow after ensuring another nurse is available to check the radial pulse at the same time.

C: This action relates to checking a pulse rate generally but does not specify the need for simultaneous comparison with the apical pulse.
D: Calculation of the difference is the final step after both pulses have been counted simultaneously.
