A nurse is caring for a patient with a fever. Which nursing intervention should be implemented first to help reduce the patient's body temperature?
A 45-year-old patient admitted with pneumonia has developed a high fever of 102.8°F (39.3°C). The patient appears flushed, reports feeling hot and uncomfortable, and has been sweating profusely. Vital signs show: temperature 102.8°F (39.3°C), pulse 110 bpm, respirations 24/min, blood pressure 128/82 mmHg, and oxygen saturation 94% on room air.

해설
Removing excess blankets and clothing is the first intervention for hyperthermia as it promotes heat loss through radiation and convection without adverse effects. Other options like medication or ice packs require orders or can cause shivering.
Core Nursing ExplanationKey Concept Analysis: This question assesses the priority nursing intervention for a patient with a fever (hyperthermia). The core principle is to use Key Point!non-pharmacological, independent nursing actions first to promote heat loss through the body's natural mechanisms (radiation, convection, evaporation) before moving to dependent interventions like medications or more aggressive cooling measures.
Answer Rationale: Option ③ is correct because it is a safe, immediate, and independent nursing action. Removing excess blankets and clothing reduces insulation, allowing heat to dissipate from the patient's skin surface through radiation (transfer to cooler surrounding air) and convection (air currents). This is the foundational first step in managing fever and is often sufficient to lower body temperature gradually and comfortably.
Distractor Analysis:
Option ① (Administer acetaminophen): While antipyretics are effective, they are a dependent nursing intervention requiring a physician's order. Administration is not the "first" step; the nurse should first implement independent measures. Furthermore, the mechanism of antipyretics (resetting the hypothalamic set-point) works in conjunction with, not as a replacement for, promoting external heat loss.
Option ② (Apply ice packs to axilla and groin): This is an aggressive cooling method. Applying ice directly can cause Watch out for confusion!vasoconstriction of superficial blood vessels, which paradoxically reduces heat loss from the skin's surface. It can also trigger intense shivering, a heat-generating muscular activity that can actually increase the body's core temperature and metabolic demand. This intervention is typically reserved for specific cases like heat stroke and requires careful monitoring.
Option ④ (Encourage cold fluids): Encouraging oral fluid intake is important for preventing dehydration associated with fever and diaphoresis (sweating). However, the primary mechanism for reducing core temperature is external heat loss. While cool fluids can provide a minor internal cooling effect, it is not the most immediate or effective first intervention for heat dissipation. Ensuring adequate hydration supports the body's overall response but doesn't directly address the insulating barrier causing heat retention.
Related Concepts: The nursing approach to fever follows a stepwise, evidence-based protocol: 1) Promote heat loss (remove covers, adjust room temperature), 2) Support the body's efforts (provide hydration), 3) Administer ordered antipyretics if needed, and 4) Monitor for complications. The goal is to reduce fever comfortably and avoid interventions that induce shivering or patient discomfort.
Concept Summary
Concept
Description
Nursing Implication
Fever (Pyrexia)
Elevated body temperature due to a reset hypothalamic set-point, often from infection.
Nursing actions target these: uncover skin (radiation), use fan (convection), tepid sponge bath (evaporation).
Shivering
Involuntary muscle contractions that generate heat.
Avoid aggressive cooling that triggers shivering, as it increases metabolic rate and O2 demand.
Antipyretic (e.g., Acetaminophen)
Medication that lowers fever by acting on the hypothalamus.
Dependent intervention; administer as ordered after/with non-pharm measures.

Monitor for side effects (e.g., liver toxicity with acetaminophen).
Apply Ice Packs
Conduction of heat to ice.
Later step for resistant fever or heat stroke; use with caution.
Can cause vasoconstriction, shivering, skin damage.
Tepid Sponge Bath
Promotes evaporation.
If fever persists after uncovering and medication.
Use tepid (not cold) water to prevent shivering.
Anatomy, Physiology & Pharmacology Points
Hypothalamus: The body's thermostat. During fever, prostaglandins reset it to a higher temperature.
Vasodilation: When the hypothalamus calls for cooling, blood vessels in the skin dilate to bring warm blood to the surface for heat loss. Covering the skin prevents this.
Acetaminophen Mechanism: Inhibits prostaglandin synthesis in the CNS, which helps reset the hypothalamic set-point to normal. It does not treat the underlying cause of fever (e.g., pneumonia).
Memory Tips
ABCs of Fever Care: Assess & Air out (remove covers), Beverages (hydrate), Call for/Check meds (antipyretics).
Shivering is Counterproductive: Remember, "Shivering Stops Successful cooling." Avoid interventions that cause it.
High-Frequency NCLEX Topics
The NCLEX frequently tests priority-setting and independent vs. dependent nursing actions. This question is a classic example: "What should the nurse do first?" The answer is almost always the safe, independent action you can take immediately without an order.
Watch Out for Question Variations!
Symptom Focus: "The patient is shivering during a fever. What is the nurse's priority action?" (Answer: Stop the cooling intervention, cover the patient to prevent further heat loss from shivering).
Pediatric Focus: "A toddler with a fever of 104°F (40°C) is irritable. Which action by the parent requires immediate nursing intervention?" (Answer: Preparing an ice bath for the child).
Medication Focus: "The nurse administers acetaminophen for fever. What patient education should be provided?" (Answer: Drink plenty of fluids, do not exceed maximum daily dose, report persistent fever).
Nursing Clinical Practice GuideClinical Scenario: You are the nurse on a medical-surgical unit. Your patient, Mr. Jones, admitted with community-acquired pneumonia, is restless, flushed, and diaphoretic. His family has piled extra blankets on him because "he said he had chills earlier." His current temperature is 102.8°F (39.3°C).
Nursing Intervention Strategy:
Assessment: Perform a focused assessment. Note the fever pattern, associated symptoms (chills, myalgia), skin condition (flushed, diaphoretic), and hydration status (mucous membranes, skin turgor). Review medications for existing antipyretic orders.
Immediate Action (First!): Key Point! Politely explain to the patient and family the need to promote heat loss. Remove the excess blankets and heavy clothing, leaving a light sheet or gown. Ensure room temperature is comfortable, not too warm.
Supportive Care: Offer cool, non-caffeinated fluids (water, juice) frequently. Place a cool, damp washcloth on the forehead if it provides comfort. Encourage rest.
Pharmacological Management: If an antipyretic (e.g., acetaminophen 650 mg PO) is ordered, administer it now that the external barriers to heat loss are removed. Document the time given.
Monitoring & Evaluation: Recheck the patient's temperature in 30-60 minutes. Assess for reduction in fever, improved comfort, and decreased diaphoresis. Monitor for signs of dehydration or worsening respiratory status.
Patient Safety and Precautions:
Avoid Shivering: Never use alcohol baths or ice water sponging, as they cause rapid vasoconstriction and shivering.
Hydration is Key: Fever increases insensible fluid loss. Monitor intake and output (I&O) closely, especially if the patient is elderly or has renal/cardiac issues.
Underlying Cause: Remember, fever is a symptom. Continue to monitor for the primary problem (e.g., respiratory status in pneumonia).
Nursing Procedure & Medication FlowProcedure: Managing Hyperthermia
1. Assess vital signs, especially temperature.
2. Remove external sources of heat retention (covers, clothing).
3. Promote a cool environment (adjust thermostat, use fan cautiously).
4. Initiate oral or IV hydration as tolerated.
5. Administer prescribed antipyretic.
6. Reassess temperature and comfort level within 1 hour.
7. Document interventions and patient response.
Medication: Acetaminophen (Tylenol)
Action: Antipyretic and analgesic.
Nursing Considerations: Check for liver disease or chronic alcohol use. Maximum daily dose is typically 3,000-4,000 mg for adults, but often lower in clinical settings. Do not give with other products containing acetaminophen.
Patient Education: "This will help lower your fever and make you more comfortable. It works best if you are not bundled up. Please drink plenty of fluids while you have a fever."
A Word from Your Senior Nurse
"In the rush of a shift, it's easy to jump straight to the medication. But never underestimate the power of a simple, independent nursing action. Removing those blankets is often the quickest way to start bringing a fever down and shows the patient you're attending to their immediate comfort. Always think: 'What can I do right now, with my own two hands and nursing judgment?' That mindset makes you an autonomous, effective clinician. For the NCLEX, they love to test this distinction between independent and dependent actions—master it!"
Fever — An elevation in body temperature above the normal range, often due to an infection or inflammatory process, resulting from a resetting of the hypothalamic set-point.
Radiation — The transfer of heat from the surface of one object to the surface of another without direct contact. A primary mechanism of heat loss from the body to the environment.
Convection — The transfer of heat away from the body by air movement. Removing blankets promotes convection by allowing air to circulate over the skin.
Shivering — Involuntary muscle contractions that generate heat. It is a counterproductive response during fever management as it increases metabolic demand and core temperature.
Antipyretic — A medication, such as acetaminophen or ibuprofen, that reduces fever by acting on the hypothalamus to lower the elevated temperature set-point.
