Which of the following vital signs is considered within normal limits for a healthy adult? a. heart rate of 70 beats per minute at rest b. heart rate of 120 beats per minute at rest c. blood pressure of 170/110 mmHg at rest d. respiratory rate of 28 breaths per minute at rest

A Broadly defined normal vital signs are as follows: heart rate = 60-100 beats per minute, respiratory rate = 12-20 breaths per minute, and blood pressure should be 120/80 mm Hg or less.

Which group would tend to have the highest resting heart rate? a. infant b. preschooler c. toddler d. adolescent

A Resting heart rate tends to be highest at birth and gradually decrease through adolescence. As a result, an infant (birth - 1 year) would tend to have the highest resting heart rate.

Which pulse site is assessed near the center of the long axis of the foot, between the first and second metatarsal bones? a. dorsal pedis b. posterior tibial c. brachial d. radial

A The key function of the anterior tibial artery is to supply blood to the muscles in the anterior leg. As the artery goes across the interosseous membrane, it branches off into the dorsalis pedis artery, which supplies blood to the dorsal surface of the foot. This pulse is congenitally absent in approximately 10% of individuals.

Which of the following is defined as the rhythmic dilation of an artery caused by the contraction of the ventricles of the heart? a. pulse b. BP c. HR d. contractility

A The most common sites for palpating pulse are the carotid arteries on the anterolateral neck and the radial arteries at the anterolateral wrist. Palpating the number of pulses in a minute is a common method of determining heart rate (beats per minute).

Which arterial pulse site is located in the midline of the posterior knee between the tendons of the hamstring muscles? a. popliteal b. posterior tibial c. femoral d. temporal

A The popliteal pulse can be palpated in the midline of the posterior knee between the hamstring tendons. The femoral, popliteal, posterior tibial, and dorsalis pedis arterial sites are commonly used to evaluate the pulse in the lower extremity.

artery located 1/3 of the distance from the pubis to the ASIS

3+ on HR amplitude scale

Match the peripheral artery with its associated location for pulse assessment: carotid

medial aspect of SCM

Match the peripheral artery with its associated location for pulse assessment: brachial

2+ on HR amplitude scale

normal or average pulsation

which common site for palpating a peripheral artery pulse is located at the wrist, lateral to the flexor carpi radialis tendon? - brachial - radial - popliteal - ulnar

radial

small or reduced pulsation

The normal resting heart rate of a young child would be: a. lower than an adult's heart rate b. higher than an adult's heart rate c. the same as an adult's heart rate d. constantly fluctuating heart rate

B A young child's heart rate is relatively high at birth and then declines with age. Normal resting heart rates of children often exceed 100 beats per minute, while heart rates of adults are most often expressed as 60-100 beats per minute. The standard deviation of heart rates becomes more narrow as children develop.

Which of the following would be a normal resting heart rate for a four-year-old child? a. 60 BPM b. 100 BPM c. 140 BPM d. 180 BPM

B Children have greater resting heart rates than adults. A normal resting heart rate for an adult is often expressed as 60-100 beats per minute, while the resting heart rate of a child may routinely exceed 100 beats per minute. As a child develops, the heart rate differential gradually diminishes.

Which pulse site is measured by palpating inferior to the angle of the mandible and anterior to the sternocleidomastoid muscle? a. brachial b. carotid c. radial d. temporal

B The carotid pulse is determined by palpating the common carotid artery with the index and middle fingers placed inferior to the angle of the mandible and anterior to the sternocleidomastoid muscle.

What is the heart rate of a patient whose heart beats 19 times in a 12 second interval? a. 76 BPM b. 95 BPM c. 114 BPM d. 190 BPM

B The heart rate per minute would be calculated by multiplying 19 x 5 since the collection period (i.e., 12 seconds) is only 1/5 or 20% of one minute.

Which pulse site is assessed by palpating the lateral volar surface of the wrist, lateral to the flexor carpi radialis tendon? a. brachial b. radial c. ulnar d. popliteal

B The radial and carotid pulses are the most common sites for assessing heart rate by both the clinician and the patient. The radial artery arises from the bifurcation of the brachial artery in the cubital fossa. After it passes through the anatomical snuff box it becomes the deep palmar arch which joins with the deep ulnar artery.

A normal sinoatrial initiated heart rate is typically: a. 20-40 BPM b. 40-60 BPM c. 60-100 BPM d. 100-120 BPM

C The normal pacing ability of the sinoatrial node is 60-100 beats per minute which is considered a normal range for a regular heartbeat.

Which assessment time period would produce the most valid measurement of resting heart rate? a. 15 seconds b. 30 seconds c. 45 seconds d. 60 seconds

D An assessment period of 60 seconds allows for the most valid measurement of resting heart rate since it minimizes the impact of any irregularity in heart rhythm.

Which group would tend to have the lowest resting heart rate? a. infant b. toddler c. preschooler d. adolescent

D Resting heart rate tends to decrease slightly from birth to adolescence. As a result, an adolescent (12-18 years) would tend to have the lowest resting heart rate.

Which pulse site is assessed by palpating on the medial aspect of the foot inferior and slightly posterior to the medial malleolus? a. dorsal pedal artery b. medial plantar artery c. popliteal artery d. posterior tibial artery

D The posterior tibial artery carries blood to the posterior compartment of the leg and the plantar surface of the foot from the popliteal artery.

Which pulse site is measured by palpating anterior and adjacent to the ear? a. brachial b. carotid c. radial d. temporal

D The temporal pulse is determined by palpating the superficial temporal artery with the index finger placed on the temple in front of the ear.

T or F: for irregular rhythms, pulses should be counted for 30 seconds

FALSE 60 seconds

T or F: high intensity pulse will be present when stroke volume is decreased

FALSE increased
