A nurse is preparing to measure an infant's vital signs. The nurse should use which of the following sites to assess a heart rate?
Brachial artery
Radial artery
Apex of the heart
Carotid artery
The Correct Answer is A
Rationale:
A. The brachial artery is commonly used to assess the heart rate in infants due to its accessibility and the ease of palpation in smaller limbs.
B. The radial artery is not typically used in infants because it is less accessible and not as easily palpated in this age group.
C. While the apex of the heart is where heart sounds are best auscultated, it is not used to palpate the pulse in infants.
D. The carotid artery is not typically used for assessing the heart rate in infants due to the risk of applying excessive pressure.

Correct Answer is A
Explanation
Rationale:
A. The FLACC scale (Face, Legs, Activity, Cry, Consolability) is designed for infants and young children who cannot verbally communicate their pain, making it suitable for a 2-month-old.
B. The FACES scale is used for older children who can point to or choose faces that represent their pain level and is not suitable for a 2-month-old.
C. The OUCHER scale is used for children aged 3 to 13 years and includes pictures representing pain, so it is not appropriate for a 2-month-old.
D. The PANAD scale is not a standard pain rating scale used for infants and is less commonly used than the FLACC scale.
Correct Answer is B
Explanation
Rationale:
A. Obtaining a blood culture is important but is not the immediate priority when a transfusion reaction is occurring.
B. Stopping the transfusion is the first step in managing a transfusion reaction to prevent further exposure to the allergen or irritant causing the symptoms.
C. Slowing the transfusion rate might not be sufficient if a reaction is occurring; stopping it is crucial.
D. Providing a diuretic is not relevant to the management of an acute transfusion reaction.
