Question 1 of 5
At 32 weeks' gestation, a client is scheduled for a fetal activity test (nonstress test). She calls the clinic and asks the RN, 'How do I prepare for the test I am scheduled for?' The RN will most likely inform her of the following instructions to help prepare her for the test:
Correct Answer: D
Rationale: Any maternal activity can interfere with the results of the nonstress test, as movement may affect fetal heart rate tracings.
Question 2 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 3 of 5
A male client is started on IV anticoagulant therapy with heparin. Which of the following laboratory studies will be ordered to monitor the therapeutic effects of heparin?
Correct Answer: A
Rationale: Partial thromboplastin time is used to monitor the effects of heparin, and dosage is adjusted depending on test results. It is a screening test used to detect deficiencies in all plasma clotting factors except factors VII and XIII and platelets. Hemoglobin is the main component of RBCs. Its main function is to carry O2 from the lungs to the body tissues and to transport CO2 back to the lungs. RBC count is the determination of the number of RBCs found in each cubic millimeter of whole blood. PT is used to monitor the effects of oral anticoagulants, e.g., coumarin-type anticoagulants.
Question 4 of 5
A first-trimester primigravida is diagnosed with anemia. The nurse should suspect that this anemia is a result of:
Correct Answer: A
Rationale: Increased maternal blood volume in the first trimester causes dilutional anemia due to a relative decrease in red blood cell concentration.
Question 5 of 5
Before administering Theo-Dur (theophylline), the nurse should check the patient's:
Correct Answer: C
Rationale: Theophylline, a bronchodilator, can cause tachycardia. Checking the pulse before administration ensures the patient is not at risk for adverse cardiac effects. Urinary output, blood pressure, and temperature are less directly affected.
