NUR 1600 - PHARMACOLOGICAL

Pharmacological Question 1 When positioned properly, the tip of a central venous catheter should lie in the: You Selected:  superior vena cava. Correct response:  superior vena cava. Explanation: When positioned correctly, the tip of a central venous catheter lies in the superior vena cava, inferior vena cava, or right atrium — that is, in the central venous circulation. Blood flows unimpeded around the tip, allowing the rapid infusion of large amounts of fluid directly into circulation. The basilic, jugular, and subclavian veins are common insertion sites for central venous catheters. Remediation: Question 2 See full question While the nurse is caring for a neonate at 32 weeks' gestation in an isolette with continuous oxygen administration, the neonate's mother asks why the neonate's oxygen is humidified. The nurse should tell the mother? You Selected:  "The humidity promotes expansion of the neonate's immature lungs." Correct response:  "Oxygen is drying to the mucous membranes unless it is humidified." Explanation: Oxygen should be humidified before administration to help prevent drying of the mucous membranes in the respiratory tract. Drying impedes the normal functioning of cilia in the respiratory tract and predisposes to mucous membrane irritation. Humidification of oxygen does not promote expansion of the immature lungs. Expansion is promoted by placing the infant in a prone position or providing the preterm infant with surfactant medication. Humidified oxygen does not prevent viral or bacterial pneumonia. In fact, in some nurseries, Staphylococcus aureus has been detected in moist environments and on the hands and nails of staff members, predisposing the neonate to pneumonia. Humidified oxygen does not improve blood circulation in the cardiac system. Remediation: Question 3 See full question A client receives an IV dose of gentamicin sulfate.
