Question 1 of 5
A client has developed diabetes insipidus after removal of a pituitary tumor. Which finding would the nurse expect?
Correct Answer: A
Rationale: Diabetes insipidus causes polyuria due to deficient antidiuretic hormone, leading to excessive water loss. Hypertension (
B), polyphagia (
C), and hyperkalemia (
D) are not typical.
Question 2 of 5
A six-month-old infant is receiving ribavirin for the treatment of respiratory syncytial virus. Ribavirin is administered via which one of the following routes?
Correct Answer: D
Rationale: Ribavirin is not supplied in an oral form. Ribavirin is administered by aerosol in order to decrease the duration of viral shedding within the infected tissue. Ribavirin is not approved for IV use to treat respiratory syncytial virus. Ribavirin is a synthetic antiviral agent supplied as a crystalline powder that is reconstituted with sterile water. A Small Aerosol Particle Generator unit aerosolizes the medication for delivery by oxygen hood, croup tent, or aerosol mask.
Question 3 of 5
A client is being discharged and will continue enteral feedings at home. Which of the following statements by a family member indicates the need for further teaching?
Correct Answer: B
Rationale: Diarrhea is a complication of tube feedings that can lead to dehydration. Diarrhea may be the result of hypertonic formulas that can draw fluid into the bowel. Other causes of diarrhea may be bacterial contamination, fecal impaction, medications, and low albumin. A consistent weight gain of more than 0.22 kg/day (1/2 lb/day) over several days should be reported promptly. The client should be evaluated for fluid volume excess. Elevating the client's head prevents reflux and thus formula from entering the airway. Bacteria proliferate rapidly in enteral formulas and can cause gastroenteritis and even sepsis.
Question 4 of 5
The medication that best penetrates eschar is:
Correct Answer: A
Rationale: Mafenide acetate is bacteriostatic and best penetrates eschar, making it effective for deep burn wounds. The other medications do not penetrate eschar as effectively.
Question 5 of 5
At 30 weeks' gestation, a client is admitted to the unit in premature labor. Her contractions are every 5 minutes and last 60 seconds, her cervix is closed, and the suture placed around her cervix during her 16th week of gestation, when she had the MacDonald procedure, can still be felt by the physician. The amniotic sac is still intact. She is very concerned about delivering prematurely. She asks the RN, 'What is the greatest risk to my baby if it is born prematurely?' The RN's answer should be:
Correct Answer: D
Rationale: Any infant would be at risk for hyperglycemia because the infant's liver is missing the islets of Langerhans, which secrete insulin to break down glucose for cellular use. Prematurity is not an added risk for hyperglycemia. Both premature and mature infants can be at risk for hypoglycemia if their mother had gestational diabetes during pregnancy or entered the pregnancy with diabetes mellitus. These infants are exposed to high levels of maternal glucose while in utero, which causes the islets of Langerhans in the infant's liver to produce insulin. After birth when the umbilical cord is severed, the generous amount of maternal blood glucose is eliminated; however, there is continued islet cell hyperactivity in the infant's liver, which can lead to excessive insulin levels and depleted blood glucose. Mature infants are born with an immature GI system. The nervous control of the stomach is incomplete at birth, salivary glands are immature at birth, and the intestinal tract is sterile. This is not the greatest risk to a premature infant. The greatest risk to a premature infant is the lack of development of the lungs, which can lead to respiratory distress syndrome due to insufficient surfactant production.
