A nurse is preparing a sterile field to perform a dressing change of a client's leg wound. Which of the following actions should the nurse take?
Hold the irrigation solution bottle 5 cm (2 in) above the sterile container.
Open the outer wrapper of the sterile package toward her body.
Place the irrigation solution bottle cap on the sterile field.
Place sterile objects at least 2.5 cm (1 in) from the edge of the sterile field.
The Correct Answer is D
A. Holding the irrigation solution bottle 5 cm (2 in) above the sterile container is incorrect because the solution should be poured into a sterile container without contaminating the sterile field. The nurse should pour the solution from a height that avoids splashing and contamination.
B. Opening the outer wrapper of the sterile package toward her body is incorrect. The outer wrapper of a sterile package should be opened away from the body to avoid contamination of the sterile field.
C. Placing the irrigation solution bottle cap on the sterile field is incorrect. The cap should not be placed on the sterile field, as it may introduce contaminants.
D. Placing sterile objects at least 2.5 cm (1 in) from the edge of the sterile field is correct. This practice maintains the sterility of the field by preventing contamination from external sources.

Correct Answer is C
Explanation
A. Make sure the crib mattress is soft.: A soft mattress is a suffocation hazard for an infant. It is recommended to use a firm mattress to reduce the risk of sudden infant death syndrome (SIDS).
B. Start using a highchair for feedings.: At 3 months of age, most infants are not developmentally ready to sit in a highchair. Feeding typically occurs while the infant is held or propped in a reclined position. Highchairs are usually introduced later, around 6 months of age, when the infant has better head and neck control.
C. Remove bibs when the infant is going to sleep.: Bibs and other items that could potentially obstruct the infant's airway should be removed before sleep to reduce the risk of suffocation. This is an important safety measure to ensure the infant's safety while sleeping.
D. Place no more than one small pillow in the crib.: Pillows should not be placed in the crib for infants, as they present a suffocation hazard. It is recommended to keep the crib free from any soft bedding, including pillows and blankets, to promote safe sleep.
Correct Answer is B
Explanation
A. Instant coffee: Instant coffee generally contains more caffeine than brewed green tea or cola soft drinks. A typical 8 oz serving of instant coffee contains about 30–90 mg of caffeine.
B. Hot cocoa: This is correct. Hot cocoa contains the least amount of caffeine compared to the other options. An 8 oz serving typically contains around 5–10 mg of caffeine.
C. Brewed green tea: Brewed green tea typically contains more caffeine than hot cocoa, with an 8 oz serving containing around 30–50 mg of caffeine.
D. Cola soft drink: Cola soft drinks typically contain more caffeine than hot cocoa, with an 8 oz serving containing about 24–46 mg of caffeine.
