When assessing the blood pressure of a school-aged child, using an adult cuff of normal size will affect the reading and produce a value that is

falsely low

indistinct

accurate

falsely high

Answer and Explanation

The Correct Answer is A

A. Falsely low. Using an adult-sized cuff on a child results in an overestimation of the cuff size, causing the cuff to not inflate properly and distribute less pressure, leading to a falsely low blood pressure reading.
B. Indistinct. The reading may be inaccurate, but it will still produce a numerical value rather than being completely indistinct.
C. Accurate. Accuracy depends on using a cuff size appropriate for the child's arm circumference. An adult cuff on a child is too large, leading to an incorrect reading.
D. Falsely high. A too-small cuff would produce a falsely high reading, but an oversized cuff produces a falsely low blood pressure.

Correct Answer is B

Explanation

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. Due to a specific stimulus B. Caused by a single physiological situation C. Universally the same for everyone D. Subjective

Correct Answer is D

Explanation

A. Due to a specific stimulus. Pain can occur with or without an identifiable stimulus. Conditions like neuropathic pain or phantom limb pain exist without an obvious external cause.
B. Caused by a single physiological situation. Pain can result from multiple factors, including tissue damage, nerve dysfunction, inflammation, and psychological influences. It is not limited to one specific physiological cause.
C. Universally the same for everyone. Pain perception varies widely between individuals due to differences in pain tolerance, cultural background, past experiences, and psychological state.
D. Subjective. Pain is defined as whatever the patient says it is, making it a subjective experience. It cannot be measured objectively, and the best indicator of pain is the patient’s self-report.
