Caregiver Basic Medical Knowledge 2 — Questions and Answers
Question 1: What is the normal resting heart rate range for an adult?
- 40-50 beats per minute
- 60-100 beats per minute (Correct answer)
- 100-120 beats per minute
- 120-150 beats per minute
Correct answer: 60-100 beats per minute
Normal resting heart rate for adults is 60-100 bpm. Rates outside this range may indicate a medical condition.
A normal adult resting heart rate falls between 60 and 100 bpm. Well-conditioned athletes may have lower rates. Tachycardia (above 100) or bradycardia (below 60) may require medical attention.
Question 2: A client's blood pressure reading is 180/110 mmHg. This indicates:
- Normal blood pressure
- Low blood pressure
- High blood pressure (hypertension) (Correct answer)
- Optimal blood pressure
Correct answer: High blood pressure (hypertension)
180/110 mmHg is a hypertensive crisis requiring immediate medical attention. Normal is around 120/80 mmHg.
A reading of 180/110 is a hypertensive crisis that can lead to stroke, heart attack, or organ damage. The caregiver should keep the client calm and contact emergency services immediately.
Question 3: Which vital sign change most likely indicates infection in an elderly client?
- Decreased appetite
- Elevated body temperature (Correct answer)
- Increased thirst
- Improved sleep
Correct answer: Elevated body temperature
Elevated temperature (fever) is a primary indicator of infection, though elderly clients may have blunted fever responses.
Fever above 100.4°F (38°C) generally indicates infection. Elderly clients may not develop high fevers even with serious infections, so also watch for confusion, increased respiratory rate, and behavior changes.
Question 4: What does a pulse oximeter measure?
- Blood pressure
- Heart rate and blood oxygen saturation (Correct answer)
- Body temperature
- Blood glucose levels
Correct answer: Heart rate and blood oxygen saturation
A pulse oximeter measures oxygen saturation (SpO2) and heart rate. Normal SpO2 is 95-100%.
A pulse oximeter uses light wavelengths to measure oxygen saturation in the blood. Normal SpO2 is 95-100%. Readings below 90% indicate significant hypoxemia requiring immediate attention.
Question 5: A client shows signs of hypoglycemia. Which symptom would you expect?
- Excessive urination and thirst
- Shakiness, sweating, and confusion (Correct answer)
- Swollen ankles and shortness of breath
- High fever and body aches
Correct answer: Shakiness, sweating, and confusion
Hypoglycemia presents with shakiness, sweating, confusion, rapid heartbeat, and irritability, requiring prompt treatment with fast-acting sugar.
Hypoglycemia occurs when blood glucose drops below 70 mg/dL. The sympathetic nervous system activates causing trembling, sweating, and rapid heartbeat. Treatment follows the 15-15 rule: 15 grams of fast-acting carbs, wait 15 minutes, recheck.
Question 6: Why should you not tell a client you are counting their breaths?
- It wastes time
- They might consciously alter their breathing pattern (Correct answer)
- Breathing rate is not important
- It is against regulations
Correct answer: They might consciously alter their breathing pattern
If the client knows their breathing is being monitored, they may change their pattern, leading to an inaccurate count.
Respiration can be both voluntary and involuntary. When people become aware of their breathing, they tend to alter it. The standard technique is to count respirations while appearing to still take the pulse. Normal adult rate is 12-20 breaths per minute.
