Extract:
Question 1 of 5
Early in her ninth month of pregnancy, a client has been diagnosed as having mild preeclampsia. In counseling her about her diet, the nurse must emphasize the importance of:
Correct Answer: D
Rationale: Women with pregnancy-induced hypertension have a reduced plasma volume secondary to venous vessel constriction, not hypovolemia; therefore, sodium restriction is not recommended. It is suggested that these women avoid extremely salty foods. Drinking six to eight glasses of water per day facilitates optimal fluid volume and renal perfusion, but it will not decrease the venous vessel constriction of pregnancy-induced hypertension. Carbohydrate needs increase during pregnancy, specifically during the second and third trimesters, but they have not been linked to pregnancy-induced hypertension. Loss of urinary protein (proteinuria) is associated with increased permeability of the large protein molecules with pregnancy-induced hypertension. Additional dietary protein also helps increase the plasma colloidal osmotic pressure. Diets deficient in protein have been linked to pregnancy-induced hypertension.
Question 2 of 5
An 8-week-old infant has been diagnosed with gastroesophageal reflux. The nurse is teaching the infant's mother to care for the infant at home. Which one of the following statements by the nurse is appropriate regarding the infant's home care?
Correct Answer: D
Rationale: Elevating the child's head to a 30-degree angle is the recommended position for gastroesophageal reflux. The supine position predisposes the child to aspiration. Small, frequent feedings with thickened formula are recommended to minimize vomiting. Antacids should be given at the same time as the feeding to improve their buffering action. The infant should be kept still after feedings to reduce the risk of vomiting and aspiration. Vigorous activities should be carried out before feedings.
Question 3 of 5
A client in labor has an order for Demerol (meperidine) 75 mg. IM to be administered 10 minutes before delivery. The nurse should:
Correct Answer: B
Rationale: Meperidine given close to delivery can cause neonatal respiratory depression due to its sedative effects crossing the placenta. The nurse should question the timing of the order.
Question 4 of 5
The initial treatment for a client with a liquid chemical burn injury is to:
Correct Answer: B
Rationale: The use of large amounts of water to flush the area is recommended for chemical burns to dilute and remove the chemical. Neutralizing solutions may extend the burn, calcium chloride is not indicated, and lanolin is not beneficial initially.
Question 5 of 5
A client presents to the emergency room with cyanosis, coughing, tachypnea, and tachycardia. She has a history of asthma. Arterial blood gas values are pH 7.28, PaO2 54, PaCO2 60, and HCO3 24. The nursing assessment of arterial blood gases indicate the presence of:
Correct Answer: B
Rationale: Respiratory acidosis is determined by low pH and elevated PaCO2.
