A nonstress test is prescribed for a pregnant client, and the client asks the nurse about the procedure. Which of the following information will the nurse provide to the client?
 
  1. The fetus is challenged by uterine contractions to obtain the necessary infor-mation.
  2. The test is an invasive procedure and requires that you sign an informed con-sent.
  3. The test will take about 2 hours and will require close monitoring for 2 hours after the procedure is completed.
  4. An ultrasound transducer that records fetal heart activity is secured over the ab-domen where the fetal heart is heard most clearly.

Question 2

The nurse caring for a client with chronic obstructive pulmonary disease (COPD) anticipates which of the following arterial blood gas (ABG) findings?
 
  1. pH, 7.40; PaO2, 90 mm Hg; CO2, 39 mEq/L; HCO3, 23 mEq/L
  2. pH, 7.32; PaO2, 85 mm Hg; CO2, 57 mEq/L; HCO3, 26 mEq/L
  3. pH, 7.47; PaO2, 82 mm Hg; CO2, 30 mEq/L; HCO3, 31 mEq/L
  4. pH, 7.31; PaO2, 95 mm Hg; CO2, 22 mEq/L; HCO3, 19 mEq/L

Answer to Question 1

4

Rationale: The nonstress test takes about 30 to 40 minutes. The test is termed nonstress because it consists of monitoring only; the fetus is not challenged or stressed by uterine contractions to obtain the necessary data. It is a noninvasive test, and an ultrasound transducer that records fetal heart activity is secured over the maternal abdomen where the fetal heart is heard most clearly. A tocotransducer that detects uterine activity and fetal movement is then secured to the maternal abdomen. Fetal heart activity and movements are recorded.

Answer to Question 2

2

Rationale: The client with COPD will exist in a state of respiratory acidosis. pH, 7.32; PaO2, 85 mm Hg; CO2, 57 mEq/L; HCO3, 26 mEq/L and pH, 7.31; PaO2, 95 mm Hg; CO2, 22 mEq/L; HCO3, 19 mEq/L reflect an acidotic pH. pH, 7.32; PaO2, 85 mm Hg; CO2, 57 mEq/L; HCO3, 26 mEq/L demonstrates increased CO2. Increased CO2 acts as an acid in the body, and is elevated in the client with COPD because of an inability to exhale well and eliminate CO2. Therefore, with a rise in CO2, there is a corresponding fall in pH. The other options are incorrect.
