Question 1 of 5
A school-age child with asthma is ready for discharge from the hospital. His physician has written an order to continue the theophylline given in the hospital as an oral home medication. Immediately prior to discharge, he complains of nausea and becomes irritable. His vital signs were normal except for tachycardia. What first nursing actions would be essential in this situation?
Correct Answer: B
Rationale: Nausea, tachycardia, and irritability are all symptoms of theophylline toxicity. The physician should be notified immediately so that a serum theophylline level can be ordered.
Question 2 of 5
Which finding is expected in the normal newborn?
Correct Answer: B
Rationale: The Moro reflex, a startle response to sudden movement, is a normal finding in newborns, present until about 3-6 months. Epstein pearls are benign but not universal, and the others are abnormal.
Question 3 of 5
The nurse is evaluating the client's pulmonary artery pressure (PAP). The nurse is aware that PAP evaluates:
Correct Answer: B
Rationale: Pulmonary artery pressure (PAP), measured via a pulmonary artery catheter, reflects systolic, diastolic, and mean pressures in the pulmonary artery, indicating right ventricular function and pulmonary circulation status.
Question 4 of 5
Often children are monitored with pulse oximeter. The pulse oximeter measures the:
Correct Answer: B
Rationale: The O2 content of whole blood is determined by the partial pressure of oxygen (PO2) and the oxygen saturation. The pulse oximeter does not measure the PO2. The pulse oximeter is a noninvasive method of measuring the arterial oxygen saturation. The PO2 is the amount of O2 dissolved in plasma, which the pulse oximeter does not measure. The affinity of hemoglobin for O2 is the relationship between oxygen saturation and PO2 and is not measured by the pulse oximeter.
Question 5 of 5
The nurse is caring for a client with a history of sickle cell anemia. Which intervention is most important during a sickle cell crisis?
Correct Answer: A
Rationale: Sickle cell crisis causes vaso-occlusion, reducing tissue oxygenation. Administering oxygen is the priority to prevent hypoxia. Cold packs worsen vasoconstriction, rest is secondary, and antibiotics are for infections.
