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.

While planning nursing process for a patient who is at risk for suicide, which of the following is the priority area for providing care :
- A. Sleep
- B. Nutrition
- C. Self-esteem
- D. Safety
Correct Answer: D
Rationale: Suicide risk demands a prioritized nursing approach under the nursing process. Sleep (choice A) and nutrition (choice B) are basic needs, but disruptions are secondary to immediate risk. Self-esteem (choice C) influences mental health, yet addressing it is a longer-term goal. Safety (choice D) is the priority, as suicidal ideation poses an acute threat to life, requiring immediate interventions like removing hazards, constant observation, and risk assessment (e.g., SAD PERSONS scale). D is correct because ensuring safety prevents harm, the first step in stabilizing the patient. Nurses must implement safety protocols, collaborate with psychiatry, and then address sleep, nutrition, and esteem, building a comprehensive care plan.
Too narrow cuff will cause what change in the Client's BP?
- A. True high reading
- B. True low reading
- C. False high reading
- D. False low reading
Correct Answer: C
Rationale: A narrow cuff e.g., under-sized overcompresses, yielding a false high BP e.g., 140/90 vs. true 120/80. True readings need proper fit; wide cuffs may lower falsely. Nurses select cuffs e.g., per arm size for accuracy, per measurement standards.

- A. Ensure you have a fire extinguisher readily available
- B. Keep the oxygen tubing loose to prevent tangling
- C. Avoid using electric heating devices in your home
- D. Use an oxygen concentrator for outdoor activities
Correct Answer: C
Rationale: Avoiding electric heating devices (C) is critical in COPD oxygen therapy teaching, as oxygen accelerates combustion, posing a fire risk. Fire extinguisher (A) is supplementary. Loose tubing (B) risks disruption. Concentrator use (D) depends on need. Safety education, per home care standards, prioritizes fire prevention.
