Situation: A 29-year-old factory worker is admitted to the psychiatric unit of a general hospital two days after his wife left him. The nurse uses theoretical models to plan his care. He paces the hallway, breathes rapidly, and talks only about his wife. He cannot follow the nurse's three-step instructions for filling out a form, but he carries out one short request at a time and knows where he is. According to Peplau, which approach fits his level of anxiety?

Peplau described four levels of anxiety. In severe anxiety the perceptual field is sharply narrowed and the person cannot solve problems or follow complex directions, though still in contact with reality; the nurse reduces stimuli and gives brief, simple directions. Exploring causes and problem solving are possible only in mild or moderate anxiety, while panic brings disorganized behavior that calls for immediate safety measures.

Anxiety level and nursing approach

Peplau’s interpersonal framework organizes anxiety into four progressive levels: mild, moderate, severe, and panic. Each level changes how much sensory information the person can take in and what kind of nursing response is realistic. The patient in this scenario is pacing, breathing rapidly, and perseverating on his wife. He cannot follow three-step instructions but can complete one short request at a time and remains oriented to place. That combination—preserved reality contact with a sharply narrowed perceptual field and inability to process multi-step directions—places him in severe anxiety.

In severe anxiety, the person’s attention is fixed on a small portion of the environment, often the perceived threat. Problem solving, exploring triggers, and learning new content are not possible because those tasks require the broader perceptual field and cognitive flexibility available only in mild or moderate anxiety. The appropriate nursing action is therefore to reduce environmental stimulation and give brief, simple directions one at a time. A quiet area supports this by removing competing sensory input, which is consistent with Peplau’s emphasis on structuring the interaction according to the patient’s current capacity.

Watch out! Asking the patient to explore what set off the anxiety or enrolling him in a problem-solving group assumes he can reflect and integrate information. Those interventions fit mild or moderate anxiety, not severe anxiety. Key point! A locked room is not a therapeutic intervention for severe anxiety. Seclusion is reserved for panic-level disorganization or imminent safety risk, and even then it is a safety measure, not a first-line anxiety-reduction strategy.

The distinction matters for test questions because the same behavior can look different depending on the anxiety level. Pacing and rapid breathing could appear in both severe anxiety and panic, but the patient’s ability to follow a one-step request and remain oriented tells you he is still in contact with reality. Panic would show disorganized, purposeless behavior and loss of reality contact, requiring immediate physical safety measures rather than simple direction-giving. Severe anxiety still allows the nurse to use a calm, structured presence to help the patient regain a sense of control.

Peplau’s model also frames the nurse-patient relationship as a therapeutic tool. The nurse does not simply give information; she adjusts the mode of communication to the patient’s anxiety level. In severe anxiety, the nurse’s role is to reduce stimuli and provide a predictable, step-by-step structure. This is the same principle used in the telephone-based anxiety intervention grounded in Peplau’s theory, where the interventionist first establishes a safe, structured interaction before attempting any exploration or skill building ^[1]. Likewise, the intervention mapping study for anxiety management in substance use disorders built its early steps around creating a calm, directive contact before moving to higher-level cognitive work ^[2]. The clinical trial using Peplau’s therapeutic communication model for patients awaiting coronary bypass similarly emphasized simple, structured communication as the foundation for reducing anxiety before any deeper discussion ^[3].

Anxiety level	Perceptual field	Ability to follow directions	Appropriate nursing approach
Mild	Broad; alert and attentive	Can follow multi-step directions and learn	Explore feelings and teach problem solving
Moderate	Narrowed but still able to focus when directed	Can follow directions with some guidance	Use structured exploration and support learning
Severe	Sharply narrowed; fixated on threat	Cannot follow complex directions; one short request at a time	Reduce stimuli; give brief, simple directions in a quiet area
Panic	Disorganized; reality contact lost	Unable to follow directions; behavior is disorganized	Ensure immediate safety; use physical interventions if needed

The self-care education study in elderly diabetic patients also reflects this principle: interventions based on Peplau’s theory begin with establishing a structured, low-stimulus interaction before attempting to teach self-care behaviors ^[4]. Teaching and problem solving are later steps, not the first move when anxiety is high.

In this scenario, the correct choice is to give brief, simple directions in a quiet area. This matches the patient’s severe anxiety level because it reduces environmental demands and works within his narrowed attention span. The other options either require cognitive capacity he does not currently have or impose a restrictive measure that is not indicated at this level.
