A nurse is collecting data from an infant. Which of the following sites is the most reliable location to check the infant's pulse?
Apical
Dorsalis pedis
Temporal
Carotid
The Correct Answer is A
A. Apical:
The apical pulse is the most reliable location to assess the pulse in infants. It is located at the apex of the heart, which is typically found at the fifth intercostal space at the midclavicular line. Assessing the apical pulse allows for a direct measure of the heart rate and rhythm, which is especially important in infants to evaluate cardiac function accurately. The apical pulse is commonly assessed using a stethoscope placed at the point of maximum impulse (PMI) on the chest.
B. Dorsalis pedis:
The dorsalis pedis pulse is located on the top of the foot, typically in the region between the first and second metatarsal bones. While the dorsalis pedis pulse can be palpated in older children and adults, it may be difficult to palpate accurately in infants, especially those with smaller or more delicate feet. Therefore, it is not the preferred site for pulse assessment in infants.
C. Temporal:
The temporal pulse is located on the side of the head, just above the ear. While the temporal pulse can be palpated in some individuals, it is not typically used to assess the pulse in infants. Palpating the temporal pulse in infants may be more challenging and less reliable compared to other pulse sites, especially given the smaller size of the temporal artery in infants.
D. Carotid:
The carotid pulse is located in the neck, alongside the trachea, and can be palpated by gently pressing the fingers against the carotid artery. While the carotid pulse is easily palpable in adults and older children, it is not typically the preferred site for pulse assessment in infants. Palpating the carotid pulse in infants carries a risk of injury to the delicate structures in the neck and may not provide an accurate representation of the pulse rate.

Correct Answer is B
Explanation
Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)
Given:
Child's weight: 10 kg
Ordered volume: 40 mL/kg
Total time: 4 hours
First, calculate the total volume of Lactated Ringer's solution needed:
Total volume = 40 mL/kg × 10 kg = 400 mL
Then, divide the total volume by the total time to find the infusion rate:
Infusion rate = 400 mL / 4 hours = 100 mL/hour
Correct Answer is B
Explanation
A. Methylprednisolone: Methylprednisolone is a corticosteroid used for long-term management and prevention of asthma exacerbations. It has anti-inflammatory effects and is not typically used for immediate relief during an acute asthma attack.
B. Albuterol: Albuterol is a short-acting beta-agonist bronchodilator, which is the first-line medication for relieving acute bronchoconstriction during an asthma attack. It works quickly to open the airways and improve breathing.
C. Fluticasone: Fluticasone is an inhaled corticosteroid used for long-term asthma control and prevention of symptoms. It has anti-inflammatory effects but is not used for immediate relief during an acute asthma attack.
D. Beclomethasone: Beclomethasone is also an inhaled corticosteroid used for long-term asthma control and prevention of symptoms. Like fluticasone, it is not used for immediate relief during an acute asthma attack.
