Correct Answer is D
Explanation
A. Increasing oxygen to 6 liters/minute may not address the underlying cause of the client's wheezing and may not be the most appropriate intervention at this time.
B. Calling for an Ambu resuscitation bag may be necessary if the client's condition deteriorates further, but it is not the initial intervention for a client with asthma exacerbation.
C. Instructing the client to lie back in bed may not be effective and may exacerbate respiratory distress.
D. Administering a nebulizer treatment with a bronchodilator (e.g., albuterol) is the most appropriate intervention for a client with asthma exacerbation experiencing wheezing and respiratory distress. Nebulizer treatments deliver medication directly to the airways, helping to relieve bronchospasm and improve breathing.
Correct Answer is A
Explanation
A. Ensure that the infant's crib mattress is firm. Rationale: A firm mattress reduces the risk of SIDS as it prevents the infant's face from sinking into the mattress, which could obstruct
breathing.
B. Prop the infant with a pillow when in a side-lying position. Rationale: Pillows should not be used with infants due to the risk of suffocation and increased risk of SIDS.
C. Swaddle the infant in a blanket for sleeping. Rationale: While swaddling can be comforting, it should be done correctly to avoid too tight swaddling, which can lead to overheating, another SIDS risk factor.
D. Place the infant in a prone position whenever possible. Rationale: Infants should be placed on their backs to sleep, not on their stomachs, as back-sleeping is associated with a decreased risk of SIDS. Prone sleeping positions are discouraged.
