Understanding Vital Signs, Height, and Weight Measurement Skills

Unit Overview

The unit focuses on Resident Care Skills, Essential Standard NA4.00, specifically Indicator 4.01, which emphasizes the understanding of nurse aide skills related to residents’ vital functions and movements. It underscores the importance of maintaining academic and skill competence for direct resident care.

Importance of Vital Signs

Vital signs are often the first indicators of potential health issues in residents, reflecting essential body processes. Such as:

• Temperature (T)

• Pulse (P)

• Respiration (R)

• Blood pressure (BP).

  The vital signs formula is expressed as TPR + BP (**with pain also recognized as the fifth vital sign, representing subjective data based on the patient's sensations.**)

  *These measurements are crucial for regulating body temperature, heart function, and breathing.

Measurement of Vital Signs

Temperature Measurement

• Heat is produced by: muscles, glands, and food oxidation

• Heat loss occurs through: respiration, perspiration, and excretion.

  Factors affecting temperature include exercise, illness, age, time of day, medications, and hydration.

• Thermometers: including non-mercury glass (oral & rectal), chemically treated paper (disposable), electronic thermometers with disposable probe covers, and tympanic thermometers for ear use, are essential for temperature measurement. Normal temperature ranges for adults are as follows:

Blue: probe for oral

Red: probe for rectal

• It is crucial to record the measurement location for accurate interpretation.

• Rectal temperature is no longer taken in humans because of a splinter nerve (vagus nerve) near the rectum that could trigger cardiac arrest( some are not aware that they have cardiac problems

“Tic-Tac-Know” - Body heat registers 1 degree warmer when taken rectally and 1 degree cooler when taken axillary compared to oral measurements, making it essential to consider the method of measurement when evaluating a patient's temperature.

Pulse Measurement

Pulse measurement indicates the health of the circulatory system. The normal adult pulse range is between 60 and 100 beats per minute, influenced by factors such as age, sex, position, drugs, emotions, and physical conditioning. Common pulse measurement sites include the radial (wrist), carotid (neck), and brachial (inner elbow).

Respiratory Measurement

Respiration involves the inhalation of oxygen and exhalation of carbon dioxide, with a normal respiratory rate ranging from 12 to 20 breaths per minute, characterized by being quiet and effortless. Factors affecting the respiratory rate include age, activity level, illness, and emotions.

Blood Pressure Assessment

Blood pressure reflects the force of blood against the walls of arteries, with systolic pressure during heart contraction and diastolic pressure during heart relaxation. A normal blood pressure range is ≤120/80 mmHg. Accurate measurement requires proper technique, including the use of a sphygmomanometer and stethoscope, ensuring the correct size cuff is used.

Height and Weight Measurement

Height and weight measurements are crucial indicators of nutritional status and medical conditions. These measurements should be taken as a baseline upon admission and as ordered. Guidelines for accurate measurement include using consistent equipment, ensuring that residents void, and having them remove footwear and outer clothing before weighing. Different scales can be utilized to meet various needs (e.g., standing, wheelchair, and bed scales).

Practical Skills Assignments

Essential skills to master in this unit include: Skill 4.01A: Oral temperature measurement using a non-mercury glass thermometer; Skill 4.01F: Count and record radial pulse; Skill 4.01H: Count and record respiration; Skill 4.01I: Measure blood pressure manually; and Skill 4.01K: Measure height and weight.

Conclusion

Mastering the measurement of vital signs, height, and weight is essential for effective resident care in nursing fundamentals.
