Which pulse's absence may not be a significant finding when a patient is admitted to the hospital?
- A. Apical
- B. Radial
- C. Pedal
- D. Femoral
Correct Answer: C
Rationale: The absence of the pedal pulse may not be significant if the patient has poor peripheral circulation or if the healthcare provider is focused on other pulse points. The pedal pulse is often weaker and may not always be palpable due to various factors, making its absence less concerning in certain situations. However, the absence of other pulses like radial or femoral pulses may indicate more critical conditions and require immediate attention.
Which of the following is not a cause of tachycardia?
- A. Fever
- B. Exercise
- C. Sympathetic nervous system stimulation
- D. Parasympathetic nervous system stimulation
Correct Answer: D
Rationale: Tachycardia is an increased heart rate, and it can be caused by various factors such as fever, exercise, and sympathetic nervous system stimulation, all of which tend to increase heart rate. However, parasympathetic nervous system stimulation typically slows the heart rate, making it the exception among the choices provided. Thus, parasympathetic nervous system stimulation is not a cause of tachycardia.
How can preserving skin integrity impact the circular chain of infection?
- A. Host
- B. Reservoir
- C. Mode of transmission
- D. Portal of entry
Correct Answer: D
Rationale: Preserving skin integrity plays a key role in breaking the chain of infection by eliminating the portal of entry for pathogens. When the skin is intact, it acts as a natural barrier that prevents pathogens from entering the body. By maintaining skin integrity through proper hygiene and wound care, the risk of infection is significantly reduced, disrupting the cycle of infection transmission.
