A nurse is planning care for a client who has a prescription for continuous enteral feedings through an NG tube.
Which of the following actions should the nurse plan to take?
Measure gastric residual volumes every 4 hr.
Advance the rate of the feeding every 2 hr.
Maintain the head of the bed at a 20° angle.
Flush the NG tube with 30 mL 0.9% sodium chloride before and after medication
The Correct Answer is A
The correct answer is choice A. Measure gastric residual volumes every 4 hr.
This is because continuous enteral feedings through an NG tube can increase the risk of aspiration, which is the inhalation of food or fluids into the lungs. Measuring gastric residual volumes (GRV) can help monitor the tolerance and absorption of the feedings and prevent overfeeding. GRV is the amount of fluid aspirated from the stomach via an enteral tube to check for gastric emptying. The normal range of GRV is less than 200 ml.
Choice B is wrong because advancing the rate of the feeding every 2 hr can lead to overfeeding, abdominal distension, nausea, vomiting and diarrhea.
The rate of the feeding should be adjusted according to the client’s nutritional needs and tolerance.
Choice C is wrong because maintaining the head of the bed at a 20° angle is not enough to prevent aspiration. The head of the bed should be elevated at least 30° to 45° during and for at least one hour after feeding.
Choice D is wrong because flushing the NG tube with 30 mL 0.9% sodium chloride before and after medication is not related to continuous enteral feedings. This is a practice to prevent clogging of the tube and ensure proper delivery of medication. Flushing the tube with water before and after feeding is also recommended to maintain patency and hydration.

Correct Answer is C
Explanation
This is because varicella, or chickenpox, is a highly contagious disease caused by the varicellazoster virus (VZV), which can spread through the air or by direct contact with the fluid from the blisters. A negative air pressure room prevents the air from the room from circulating to other areas of the hospital, reducing the risk of transmission to other patients and staff.
Choice A is wrong because aspirin should not be given to children with chickenpox, as it can cause a serious condition called Reye’s syndrome, which affects the brain and liver. Instead, acetaminophen can be used to reduce fever.
Choice B is wrong because droplet precautions are not enough to prevent the spread of chickenpox. Droplet precautions involve wearing a mask and gloves when in close contact with the patient, but they do not prevent the virus from traveling through the air. Airborne precautions, which include a negative air pressure room and wearing a respirator, are needed for chickenpox.
Choice D is wrong because Koplik spots are not a sign of chickenpox, but of measles, another viral infection that causes a rash. Chickenpox causes an itchy rash with small, fluid-filled blisters that crust over.
Correct Answer is D
Explanation
Hypertonicity is a sign of increased muscle tone and stiffness, which can indicate that the newborn is experiencing withdrawal from methadone exposure in utero. Methadone is an opioid medication that can cross the placenta and cause neonatal abstinence syndrome (NAS) in the newborn.
Choice A, acrocyanosis, is wrong because it is a normal finding in newborns.
Acrocyanosis is a bluish discoloration of the hands and feet due to immature peripheral circulation. It usually resolves within the first 24 to 48 hours of life.
Choice B, bradycardia, is wrong because it is not a typical sign of withdrawal.
Bradycardia is a slow heart rate, usually less than 100 beats per minute in newborns. It can be caused by hypoxia, hypothermia, hypoglycemia, or vagal stimulation.
Choice C, bulging fontanels, is wrong because it is a sign of increased intracranial pressure, not withdrawal. Bulging fontanels can be caused by meningitis, hydrocephalus, or hemorrhage.
Normal ranges for newborn vital signs are as follows:
- Heart rate: 120 to 160 beats per minute
- Respiratory rate: 30 to 60 breaths per minute
- Temperature: 36.5 to 37.5°C (97.7 to 99.5°F)
- Blood pressure: 60 to 80 mm Hg systolic and 40 to 50 mm Hg diastolic
