Study Notes
Ophthalmoscope and Eye Examination
- Ophthalmoscope examines the fundus, red reflect, macula, and optic disc of the eye.
Hypertension Risk Factors
- Stress, family history of hypertension, high sodium intake, and excessive calorie intake contribute to the development of hypertension.
Rhonchi Characteristics
- Rhonchi are low-pitched, continuous breath sounds commonly heard during lung auscultation.
- They have a deeper rumbling sound, are continuous throughout the respiratory cycle, and are best heard on expiration.
Urine Specific Gravity
- Normal specific gravity is 1.010-1.030, indicating kidney's ability to concentrate particles in urine.
Popliteal Pulse
- Located behind the knee, indicating blood flow to the lower leg.
Visual Acuity Measurement
- Notation "20/60" indicates the testing distance (20 feet) versus how far a person with normal vision can see (60 feet), signifying poorer than average vision.
Normal Breath Sounds
- Bronchovesicular sounds are normal and located between the first and second intercostal spaces over the main bronchi.
Symptoms and Physical Assessment
- Symptoms are subjective data; palpation at the PMI reflects left ventricle pulsations, typically at the fifth ICS in the left MCL.
Auscultation Techniques for Heart Sounds
- Use the bell of the stethoscope to detect low-pitched S3 heart sounds over the tricuspid or apical area.
- The diaphragm is better for high-pitched sounds (S1 and S2) and Erb's point is not optimal for S3.
Nursing Assessment Elements
- Involves asking questions, listening, data collection through system assessments, and reviewing lab results.
Correct Assessment Techniques for Respiratory/Cardiac
- Auscultate vesicular lung sounds bilaterally and palpate chest excursion at the 9th or 10th rib.
- Check capillary refill and tactile fremitus while the patient vocalizes “99”.
Pulse Pressure
- The difference between systolic and diastolic pressure indicates cardiac output; a normal difference is 30-40 mmHg.
Normal Urine Output
- Average adult urine output is 1,500 mL per day.
Pulse Oximetry
- Measures circulating blood oxygen; requires warm, dry fingers and no obstructive fingernail polish for accurate readings.
Jendrassik Maneuver
- Used to elicit the patellar reflex by having the patient clench teeth and interlock fingers while pulling.
Shock Indicators
- Elevated pulse (128 bpm) and decreased blood pressure (80/50 mmHg) signal shock; fever may indicate sepsis.
Chief Complaint in Assessment
- Follows demographic data collection from the client.
Hearing Assessment Tools
- Tuning fork and otoscope are used for ear and hearing evaluation.
Cheyne-Stokes Breathing Pattern
- Characterized by a cyclical pattern of increasing and decreasing breath depth, followed by periods of apnea.
Crackles Sound Identification
- Intermittent, non-musical sounds produced as air travels through liquid in the lungs, often heard on inspiration.
Abdominal Assessment Method
- IAPP: Inspection, Auscultation, Palpation, and Percussion.
Bradycardia
- Define and recognize slowed heart rate, which may have clinical significance.
