A nurse is about to administer an intermittent enteral feeding to a client who has an NG tube in place. Besides obtaining an x-ray, which of the following methods should the nurse use to verify the placement?
Inject air and listen for bubbling.
Test the pH of the gastric aspirate.
Measure the gastric residual.
Add food coloring to the formula.
The Correct Answer is B
This is done by aspirating a small amount of stomach contents and testing the pH using pH paper or a pH indicator strip. The pH of stomach contents is typically acidic (pH less than 5), indicating proper placement in the stomach.
Injecting air and listening for bubbling is not a reliable method to verify tube placement, as it can lead to complications such as pneumothorax.
Measuring gastric residual is done to assess the amount of gastric contents remaining in the stomach, but it does not confirm tube placement.
Adding food coloring to the formula is not a standard practice and does not provide reliable confirmation of tube placement.
X-ray is the gold standard method to confirm tube placement but is not typically done before every intermittent feeding unless there are concerns about tube placement

Correct Answer is D
Explanation
Varicella zoster, also known as chickenpox, is a highly contagious viral infection that can be spread through contact with respiratory secretions or fluid from the vesicular rash.
Contact precautions include wearing gloves and gown when in contact with the client or any potentially contaminated surfaces or materials, and isolating the client in a private room if possible.
Assigning the client to a negative pressure airflow room is not necessary unless the client has a compromised immune system or is experiencing severe respiratory symptoms.
Having visitors remain at least 0.91 m (3 feet) away from the client is not sufficient to prevent the spread of the virus.
Administering aspirin to a client with varicella zoster is contraindicated because it can increase the risk of developing Reye's syndrome, a potentially fatal condition.
Correct Answer is B
Explanation
The guideline of being able to fit one finger between the mattress and the side of the crib ensures that there is a safe space to prevent entrapment and suffocation risks.
Placing a newborn on a pillow for sleep is unsafe. Infants should be placed on their backs to sleep on a firm, flat surface without pillows, blankets, or soft bedding. This reduces the risk of suffocation or sudden infant death syndrome (SIDS).
Attaching a pacifier to the newborn's clothing with a string is hazardous. Strings and cords pose a strangulation risk. Pacifiers should be used according to safe guidelines, but they should not be attached to the baby's clothing with any type of string or cord.
Placing a newborn's crib near a heat vent can result in overheating, which is a safety concern. It is important to keep the baby's sleep environment at a comfortable temperature without direct exposure to heat sources or drafts
