Hold hands folded below the waist after donning sterile gloves

Pick up and pour solutions with the palm of the hand covering bottle labels

Keep sterile items within a 1.3 cm (0.5 in) border of the sterile drape

Maintain sterile objects within the line of vision

Answer and Explanation

The Correct Answer is D

Maintain sterile objects within the line of vision.

A. Hold hands folded below the waist after donning sterile gloves. This is incorrect because holding hands below the waist can contaminate the gloves with microorganisms from the floor or clothing.
B. Pick up and pour solutions with the palm of the hand covering bottle labels. This is incorrect because covering bottle labels can obscure important information such as expiration dates or ingredients.
C. Keep sterile items within a 1.3 cm (0.5 in) border of the sterile drape. This is incorrect because the border of the sterile drape is considered contaminated and any sterile item that touches it becomes contaminated as well.
D. Maintain sterile objects within the line of vision. This is correct because keeping an eye on sterile objects ensures that they are not accidentally touched by nonsterile items or persons.

Correct Answer is D

Explanation

Have the client wear a surgical mask while being transported outside the room.

A. Initiate contact precautions for the client upon admission. This is incorrect because contact precautions are not sufficient to prevent the spread of TB, which is an airborne disease that can travel through small droplets in the air.
B. Restrict visitors from entering the client's room during hospitalization. This is incorrect because visitors can enter the client's room as long as they wear appropriate personal protective equipment (PPE) such as an N95 respirator, gown, gloves, and eye protection.
C. Wear a surgical mask while providing care for the client. This is incorrect because a surgical mask does not filter out small airborne particles that carry TB bacteria. The nurse should wear an N95 respirator or higher level of respiratory protection when caring for a client who has active TB.
D. Have the client wear a surgical mask while being transported outside the room. This is correct because a surgical mask can reduce the amount of droplets that are expelled by the client when coughing or sneezing, thus minimizing the risk of infecting others in common areas or hallways.

A. Sodium 142 mEq/L. B. Respiratory rate 22/min. C. Potassium 3.9 mEq/L. D. Heart rate 148/min.

Correct Answer is D

Explanation

Choice A rationale:

Sodium level of 142 mEq/L is within the normal range (135-145 mEq/L) for adults. However, normal ranges for children might vary slightly, but 142 mEq/L is not indicative of dehydration on its own.

Choice B rationale:

Respiratory rate of 22/min is within the normal range for a 3-year-old child (20-30 breaths/min) This rate alone does not provide evidence of dehydration.

Choice C rationale:

Potassium level of 3.9 mEq/L is within the normal range (3.5-5.1 mEq/L) for children. Like sodium, normal ranges for potassium may differ slightly in pediatric patients, but 3.9 mEq/L is not alarming on its own.

Choice D rationale:

Heart rate of 148/min is elevated for a 3-year-old child. Tachycardia is a common sign of dehydration in pediatric patients. This increased heart rate indicates the body's compensatory mechanism to maintain cardiac output in response to decreased blood volume, a typical consequence of dehydration.
