Question 1 of 5
The nurse is preparing to administer a dose of ondansetron (Zofran) for nausea. Which route is most appropriate for rapid onset?
Correct Answer: C
Rationale: Intravenous ondansetron provides the fastest onset for nausea relief, ideal in acute settings. Oral and sublingual routes are slower, and IM is less common.
Question 2 of 5
Which of the following nursing care goals has the highest priority for a child with epiglottitis?
Correct Answer: A
Rationale: Of these four goals, maintenance of a calm, quiet atmosphere to reduce anxiety and to allow for rest is the most important. Although nutrition is important, the child needs fluids to maintain fluid and electrolyte balance more than solid foods. In addition, the child may not be able to swallow solid foods owing to epiglottic swelling. This goal is unrealistic because fever is a common symptom of the infection associated with epiglottitis. If overexerted, the child will need more O2 and energy than available, and these requirements may exacerbate the condition.
Question 3 of 5
A client with a history of gout is receiving Allopurinol (Zyloprim). The nurse should teach the client to:
Correct Answer: A
Rationale: Allopurinol reduces uric acid, and increased fluid intake promotes uric acid excretion, preventing kidney stones. Dairy, empty stomach, and protein limits are not necessary.
Question 4 of 5
The nurse is teaching a client with a history of hypertension about medication adherence. The nurse should tell the client to:
Correct Answer: A
Rationale: Adherence to antihypertensives is critical in hypertension to maintain blood pressure control and prevent complications.
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.
