Increase in the depth of respiration is ?

Appeared in: RUHS, Jaipur, PB B.Sc Nursing Entrance-2021

Explanation

Hyperpnea is defined as an increase in the depth of breathing (increased tidal volume).
This change in breathing pattern can occur with or without an increase in the respiratory rate.
It is a common physiological response to exercise, as the body's metabolic demands for oxygen increase.
Pathologically, it can be seen in conditions like metabolic acidosis, where deep breathing helps to compensate by blowing off carbon dioxide.

Option A: Apnea is the complete absence or temporary cessation of breathing, which is the opposite of an increase in respiration.
Option B: Orthopnea refers to difficulty breathing specifically when lying down (supine position), which is relieved by sitting up. It relates to posture, not just the depth of breathing.
Option C: Tachypnea is an increase in the rate of breathing (more breaths per minute), not necessarily the depth. Breathing in tachypnea is often rapid and shallow.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Terminology of Respiratory Patterns as background academic context rather than a clinical decision trigger.
Accurately identifying and documenting a patient's respiratory pattern is a fundamental nursing skill. It provides crucial clues to the patient's underlying physiological state and potential diseases.
For example, observing hyperpnea in a diabetic patient could be an early sign of diabetic ketoacidosis (DKA), prompting an immediate blood glucose and ketone check.
Distinguishing between tachypnea and hyperpnea is vital. Tachypnea might suggest fever or anxiety, while hyperpnea points more towards a metabolic issue or significant exertion.

How to Approach the Question

This is a factual recall question that tests your knowledge of medical terminology.
First, identify the key phrase in the question: 'increase in the depth of respiration'.
Next, systematically review the definition of each option.
Apnea means 'no breathing'.
Orthopnea relates to difficulty breathing when lying 'flat' (ortho- means straight/upright, -pnea means breathing).
Tachypnea means 'fast breathing' (tachy- means fast).
