A nurse is caring for a client who acquired hepatitis A from consuming contaminated food. The client’s mouth is an example of which of the following links in the chain of infection?
Portal of entry
Infectious agent
Susceptible host
Reservoir
The Correct Answer is A
The chain of infection describes how an infection spreads based on six links of transmission: Infectious Agent, Reservoirs, Portal of Exit, Modes of Transmission, Portal of Entry, and Susceptible Host1. In this case, the client’s mouth is an example of a portal of entry, which is the route by which an infectious agent enters a new host1.

Correct Answer is B
Explanation
The correct answer is b.
Choice A: SpO2 95%
The normal range for SpO2, or peripheral capillary oxygen saturation, is typically between 95% and 100%. While a SpO2 of 95% is within the normal range, it doesn't necessarily indicate an understanding of vital signs as it's on the lower end of the normal range.
Choice B: Right radial pulse regular 68/min
The normal resting heart rate for adults ranges from 60 to 100 beats per minute. Therefore, a right radial pulse of 68 beats per minute falls within the normal range and indicates an understanding of vital signs.
Choice C: Temp 36°C (96.8°F)
The normal body temperature for a healthy adult can range from 97.8°F (36.5°C) to 99.1°F (37.3°C). Therefore, a body temperature of 36°C (96.8°F) is slightly below the normal range.
Choice D: BP 148/72 mm Hg
The normal range for blood pressure in adults is between 90/60 mmHg and 120/80 mmHg. A blood pressure reading of 148/72 mm Hg is above the normal range for systolic pressure (the top number), indicating high blood pressure (hypertension).
