Carotid pulse

Brachial pulse

Posterior tibialis

Femoral pulse

Answer and Explanation

The Correct Answer is C

A: This is not suitable for assessing circulation issues specifically in the lower extremities as it is located on the upper body.

B: This is not suitable for assessing circulation issues specifically in the lower extremities as it is located on the upper body.
C: Palpating the posterior tibialis pulse is a logical next step for checking lower extremity circulation, particularly when dorsalis pedis is not palpable, helping localize the evaluation of blood flow in the foot and ankle.
D: The femoral pulse is useful for broader leg circulation issues. However, it is less targeted than posterior tibialis for checking blood flow in the lower extremities.

Correct Answer is D

Explanation

A. Decreased plasma volume might cause overall weak pulses but would unlikely cause an absent pulse specifically localized in one or more extremities. Decreased plasma volume generally affects circulation systemically, not selectively in certain limbs.
B. Problems with the heart's electrical conduction system primarily affect the rhythm and rate of the heart but do not directly cause absent pulses in extremities. These issues lead to irregular or abnormal heartbeats, not localized absence of pulses.
C. Shock can result in weak or thready pulses due to poor blood flow, but shock alone would not typically cause a pulse to be completely absent in one extremity while present in others. Shock affects the circulatory system as a whole.

D. A blockage of blood flow is the most likely cause of an absent pulse in one or more extremities. This could be due to atherosclerosis, embolism, or thrombosis, which can obstruct blood flow in specific areas, leading to no detectable pulse in those extremities.

A. Anisocoria of the patient's pupils. B. Patient's accommodation response. C. Direct pupil response of the patient. D. Patient's consensual reflex.

Correct Answer is B

Explanation

A: Anisocoria refers to a condition where the pupils are of unequal sizes, which is not related to focusing ability.

B: Accommodation response involves the ability of the eye to change focus from distant to near objects, demonstrating the flexibility of the lens which is exactly what the instruction aims to test.
C: Direct pupil response relates to pupil constriction in response to light, not changes in focal distance.
D: Consensual reflex also refers to the reaction of both pupils to light and would not be assessed through changes in focal distance.
