A primigravida client at 39 weeks gestation is in active labor with contractions occurring every 3 minutes lasting 60 seconds. She appears anxious and states "I can't do this anymore, the pain is too intense." What is the most appropriate nursing intervention to help this client manage her labor pain?
1Encourage the client to hold her breath during contractions to reduce oxygen consumption
2Instruct the client to take rapid, shallow breaths throughout the entire contraction
3Advise the client to breathe normally and focus on relaxation between contractions only
4Teach the client to use slow, deep breathing at the beginning and end of contractions with modified breathing during the peak✓ 정답
해설
Slow, deep breathing with modified patterns during peak contractions optimizes oxygenation and pain management, while other options (breath-holding, rapid breathing, or relaxation-only focus) can lead to hyperventilation or inadequate coping.
A primigravida at term in active labor is experiencing intense pain and expressing feelings of being overwhelmed. This is a classic presentation of the emotional and physical crisis of the transition phase or late active phase of the first stage of labor. The client’s statement, "I can't do this anymore," signals a loss of control and heightened anxiety, which can amplify pain perception through the fear-tension-pain cycle. The priority nursing intervention is not to eliminate pain entirely—since labor is a physiological process—but to equip the client with a cognitive-behavioral coping strategy that restores her sense of control and works with her body’s physiology.
Analysis of the Correct Answer (Option 4)
The most appropriate intervention is to teach the client to use slow, deep breathing at the beginning and end of contractions with modified breathing during the peak. This structured, patterned breathing technique is a cornerstone of non-pharmacological pain management (NPPM) for several physiological and psychological reasons.
- Physiological Mechanism: Slow, deep breathing promotes relaxation by stimulating the parasympathetic nervous system. This counteracts the sympathetic "fight-or-flight" response triggered by pain and anxiety, which can lead to increased muscle tension, elevated maternal heart rate, and reduced uteroplacental perfusion. By maintaining oxygenation and reducing tension, the client can work more effectively with her contractions. Modified, lighter breathing at the contraction’s peak prevents the client from holding her breath and bearing down prematurely against an incompletely dilated cervix, which could cause cervical edema and impede labor progress.
- Psychological Mechanism: Providing a specific, rhythmic task to focus on serves as a powerful cognitive distraction. It redirects the client’s attention away from the pain stimulus and toward a controllable action, breaking the fear-tension-pain cycle. This restores a sense of mastery and reduces the overwhelming anxiety expressed in her statement. A systematic review confirms that such NPPM strategies are safe and effective for managing labor pain, offering women an active role in their birth experience [1].
Critique of Incorrect Options
- Option 1 (Hold her breath): This is contraindicated. Holding her breath during a contraction constitutes a Valsalva maneuver. This sharply increases intrathoracic pressure, which can reduce venous return, decrease maternal cardiac output, and transiently lower blood pressure, potentially compromising fetal oxygenation. It also increases tension and is an ineffective pain-coping strategy.
- Option 2 (Rapid, shallow breaths throughout): This pattern will quickly lead to hyperventilation. Excessive exhalation of carbon dioxide causes respiratory alkalosis, which can manifest as dizziness, tingling in the fingers and lips (paresthesia), and lightheadedness. This adds distressing physical symptoms to an already painful experience and impairs the client’s ability to cope.
- Option 3 (Breathe normally and relax only between contractions): This advice is incomplete and ineffective for active labor. While relaxation between contractions is crucial for conserving energy and restoring uterine blood flow, the client needs a specific breathing strategy during the contraction itself to manage the peak of the pain. Telling her to "breathe normally" during intense pain offers no structured coping mechanism and is unlikely to be achievable.
Integration of Evidence-Based Practice
The emphasis on structured breathing aligns with the growing body of evidence supporting non-pharmacological pain management (NPPM) as a safe and effective first-line approach. While pharmacological options like epidural analgesia are the gold standard for pain relief, they carry risks for both mother and baby [1]. NPPM techniques, including patterned breathing, empower the laboring woman and can be used alone or in combination with other methods. Research into various NPPM modalities, such as the Rebozo technique which uses rhythmic pelvic movement to promote relaxation , and even technology-assisted interventions like virtual reality for cognitive distraction , all share a common goal: to reduce pain perception by promoting relaxation and shifting the client’s focus. Similarly, culturally tailored auditory interventions have been shown to reduce pain and improve comfort by fostering a calming environment . The correct breathing technique in this scenario is a fundamental, immediately available NPPM tool that directly addresses the client’s acute anxiety and pain by providing a structured, physiology-based coping strategy.

Clinical Guide: Patterned Breathing for Labor Pain
Objective: Equip the laboring client with a cognitive-behavioral strategy to break the fear-tension-pain cycle and enhance physiological coping during active labor.
Step 1: Assessment & Timing
Identify the phase of labor (active phase: contractions every 2-5 minutes, lasting 45-70 seconds).
Assess for verbal and non-verbal cues of overwhelming pain and anxiety (e.g., "I can't do this," crying, loss of focus).
Rule out complications requiring medical intervention before initiating coaching.
Step 2: Teach the Breathing Pattern
Cleansing Breath: Instruct the client to take a deep, relaxing breath in through the nose and out through the mouth at the very start and end of each contraction. This signals the beginning and end of the structured coping period.
Slow-Paced Breathing (Early/End Phase): Guide the client to breathe slowly, at approximately half her normal respiratory rate. Focus on raising the abdomen on inhalation.
Modified-Paced Breathing (Peak Phase): As contraction intensity peaks, instruct the client to switch to lighter, shallower breaths at a faster rate (pant-blow or patterned hee-hee-who). The rate should accelerate and decelerate in a bell-shaped curve mirroring the contraction.
Step 3: Coaching & Reinforcement
Breathe with the client during the first few contractions to model the technique.
Use a calm, firm voice and maintain eye contact. Count breaths aloud if helpful.
Reinforce that the technique works with, not against, the contraction.
Monitor for signs of hyperventilation (tingling, dizziness). If present, instruct the client to cup her hands over her mouth and nose or slow the breathing rate.
Physiological Rationale
Slow, deep breathing stimulates the parasympathetic nervous system, reducing muscle tension and maternal heart rate.
Providing a cognitive task (focusing on the breathing pattern) reduces the perception of pain by occupying the cerebral cortex.
Key Considerations
This is a non-pharmacological method; always complement with emotional support, position changes, and pharmacological options as requested or indicated.
Document the client's response to the intervention and any adjustments made to the breathing pattern.
Fear-Tension-Pain Cycle — A physiological feedback loop where anxiety increases muscle tension, which amplifies pain perception, leading to more fear and further tension, often hindering labor progress.
Patterned Breathing — A conscious breathing technique using varying depths and rates during different phases of a contraction to promote relaxation, oxygenation, and a sense of control during labor.
Uteroplacental Perfusion — The blood flow from the mother to the placenta, which is essential for fetal oxygenation and can be compromised by excessive maternal sympathetic nervous system activation and vasoconstriction.
