Which of the following statement is NOT true about pulse pressure?
- A. Pulse pressure is the difference between the systolic and diastolic pressure
- B. Normal pulse pressure is 40 mmHg
- C. Pulse pressure increases when the systolic pressure is elevated and the diastolic pressure remains the same
- D. Elderly people have decreased pulse pressure due to loss of elasticity in the blood vessels
Correct Answer: D
Rationale: Pulse pressure is systolic minus diastolic (A), typically 40 mmHg (B), and rises if systolic increases with stable diastolic (C), per cardiovascular norms. Elderly have increased pulse pressure (D) due to arterial stiffness systolic rises, diastolic may drop making D untrue. Aging widens pulse pressure, not narrows it, contradicting D, thus it's the correct answer as the false statement.

Which of the following nursing intervention is appropriate to prevent pulmonary embolus in a patient who is prescribed bed rest?
- A. Limit the client's fluid intake
- B. Encourage deep breathing and coughing
- C. Use the knee gatch when the client is in bed
- D. Teach the patient to move legs in bed
Correct Answer: D
Rationale: Bed rest risks venous stasis, a pulmonary embolus cause. Leg movement promotes circulation, preventing clots from forming and traveling to lungs. Fluid limits dehydration but not emboli directly, deep breathing aids lungs but not veins, and knee gatch increases stasis. Nurses teach exercises, reducing thromboembolism risk, enhancing recovery safety.
Which of the following do not correctly correlates the increase BP of Ms. Aida, a 70 year old diabetic?
- A. Females, after the age 65 tends to have lower BP than males
- B. Disease process like Diabetes increase BP
- C. BP is highest in the morning, and lowest during the night
- D. Africans, have a greater risk of hypertension than Caucasian and Asians.
Correct Answer: A
Rationale: Females over 65 often have higher BP e.g., post-menopause not lower, contradicting Aida's rise. Diabetes (vessel damage), morning peaks (circadian), African risk (genetics) align. Nurses note this e.g., elderly diabetics for management.
He was called the father of sanitation.
- A. Abraham
- B. Hippocrates
- C. Moses
- D. Willam Halstead
Correct Answer: C
Rationale: Moses, in ancient Hebrew texts, introduced sanitation laws e.g., waste disposal, quarantine earning the ‘father of sanitation' title. Abraham (patriarch), Hippocrates (medicine), and Halstead (surgery) differ. His rules, like Leviticus' hygiene codes, predate modern sanitation, influencing public health and nursing's infection control roots.
An 8.5 lb, 6 oz infant is delivered to a diabetic mother. Which nursing intervention would be implemented when the neonate becomes jittery and lethargic?
- A. Administer insulin
- B. Administer oxygen
- C. Feed the infant glucose water (10%)
- D. Place infant in a warmer
Correct Answer: C
Rationale: Jitteriness and lethargy suggest hypoglycemia, common in infants of diabetic mothers; glucose water corrects this.
When you discover an electrical fire and decide you need a fire extinguisher, you will need to find a fire extinguisher that is rated for which class of fire?
- A. Class A
- B. Class B
- C. Class C
- D. Class E
Correct Answer: C
Rationale: An electrical fire requires a Class C extinguisher, designed for energized electrical equipment like appliances or wiring. Class A suits ordinary combustibles (wood), Class B handles flammable liquids, and Class E isn't standard (often confused with electrical but not U.S.-classified). Using a Class C extinguisher, typically with non-conductive agents like carbon dioxide, ensures safety by avoiding shock while extinguishing. This choice protects both the nurse and client in a healthcare setting, aligning with fire safety protocols.
