A nurse is assessing a client's peripheral circulation. In which of the following locations should the nurse palpate to assess the posterior tibial pulse? (Selectable areas, or "Hot Spots," are outlined in the artwork below. Select only the outlined area that corresponds to your answer.)
Iliac
Femoral
Popliteal
Tibial
The Correct Answer is D
A. The iliac pulse is located near the pelvis and is not used for assessing circulation in the lower extremities.
B. The femoral pulse is located in the upper thigh, not near the posterior tibial area.
C. The popliteal pulse is found at the back of the knee and is higher than the posterior tibial location.
D. The posterior tibial pulse is correctly located behind the medial malleolus on the inner side of the ankle. This location is where the posterior tibial artery is accessible and is commonly used to assess blood flow to the lower extremities.

Correct Answer is A
Explanation
A. Assessing visual acuity directly tests cranial nerve II (the optic nerve), which is responsible for vision.
B. Eliciting the gag reflex tests cranial nerves IX (glossopharyngeal) and X (vagus), not cranial nerve II.
C. Checking for pupillary response to light primarily assesses the function of cranial nerve II but is more associated with cranial nerve III (oculomotor) since it involves the constriction of the pupil. While relevant, it is not the best standalone action for assessing cranial nerve II specifically.
D. Observing for facial symmetry is associated with cranial nerve VII (facial nerve), not cranial nerve II.
Correct Answer is C
Explanation
A. The right upper quadrant is typically associated with gallbladder or liver issues, not duodenal ulcers.
B. The right lower quadrant is primarily associated with appendicitis or other conditions involving the appendix.
C. The left upper quadrant is where the duodenum is located, making it the appropriate area to assess for pain related to a duodenal ulcer.
D. The left lower quadrant is often associated with conditions affecting the sigmoid colon or left ovary but not typically with duodenal ulcers.
