The physician orders Benadryl elixir 37.5 mg po for hives. Available: 12.5mg/5 mL. How many milliliters will the nurse administer?

A. Brachial artery. The brachial pulse is commonly used in infants but is not the best choice for assessing circulation in an unconscious adult.
B. Carotid artery. The carotid artery is the preferred site for assessing a pulse in an unconscious adult because it is a central pulse with strong circulation, even in low-perfusion states.
C. Radial artery. The radial pulse is a peripheral pulse and may be difficult to palpate if the patient has poor circulation or cardiac arrest. The carotid pulse is more reliable in emergencies.
D. Apical artery. There is no apical artery; the apical pulse is auscultated over the heart with a stethoscope and is not used in emergency pulse checks.

A. Apical. The apical pulse, located at the apex of the heart, provides the most accurate measurement of heart rate, especially in patients with irregular rhythms. It is assessed by auscultation with a stethoscope over the fifth intercostal space at the midclavicular line.
B. Radial. The radial pulse is commonly used for routine pulse checks, but it may be less accurate in cases of irregular heart rhythms or weak peripheral circulation.
C. Brachial. The brachial pulse is typically used in infants and for blood pressure measurements, but it is not the most accurate method for assessing heart rate.
D. Popliteal. The popliteal pulse is located behind the knee and is used to assess circulation to the lower extremities, not for measuring heart rate accurately.
