A medical assistant is examining a rash on the front of a patient's arm. Which of the following terms should the assistant use to document the location of the ra
Anterior
Posterior
Lateral
Medial
The Correct Answer is A
A. Anterior: The term "anterior" refers to the front of the body, so it is appropriate for describing a rash on the front of the patient's arm.
B. Posterior: "Posterior" refers to the back of the body, which is not the location of the rash in this scenario.
C. Lateral: "Lateral" refers to the side of the body. While the rash may be on the side of the arm, it is more specifically described as anterior.
D. Medial: "Medial" refers to the midline of the body, not specifically to the front of the arm.

Correct Answer is C
Explanation
A. Exposure to a mosquito bite: Hepatitis B is not transmitted through mosquito bites. It is primarily transmitted through contact with infected body fluids, particularly blood.
B. Consumption of raw shellfish: Hepatitis A, not Hepatitis B, can be contracted through the consumption of contaminated food or water, including raw shellfish.
C. Blood splashes to the mucous membranes: Hepatitis B can be transmitted through exposure to infected blood or body fluids, including splashes to mucous membranes (e.g., eyes, mouth).
D. Direct skin contact with a patient who is infected: Hepatitis B is not transmitted through casual skin contact. It requires contact with infected body fluids.
Correct Answer is A
Explanation
A. Deflate the cuff slowly until the last sound is heard. The diastolic reading is determined when the last sound (Korotkoff sound) is heard as the cuff is deflated.
B. Listen for the first sound through the stethoscope: The first sound corresponds to the systolic reading, not the diastolic.
C. Document the reading when the gauge needle jumps: The gauge needle jump is not a reliable indicator of blood pressure readings.
D. Inflate the cuff to at least 180 mm Hg, deflate the cuff slowly, and listen for the first sound: Inflating to 180 mm Hg is unnecessary and might cause discomfort; also, the first sound is the systolic reading, not the diastolic.
