ATI Maternal Newborn Proctored Exam
1. When reviewing the arterial blood gas values for a client, a nurse notes a pH of 7.32, PaCO2 of 48 mm Hg, and HCO3 of 23 mEq/L. What does this indicate about the acid-base balance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: Respiratory acidosis
Rationale: The given values suggest respiratory acidosis. In respiratory acidosis, the pH is low (<7.35), PaCO2 is high (>45 mm Hg), and the HCO3 is normal or slightly elevated. In this scenario, the low pH (7.32) and high PaCO2 (48 mm Hg) indicate respiratory acidosis, where there is an excess of carbon dioxide in the blood, leading to acidification of the body fluids.
2. A client who experienced a cesarean birth due to dysfunctional labor expresses disappointment for not having a natural childbirth. Which response should the nurse make?
- A. Validate the client's feelings by saying, 'It sounds like you are feeling sad that things didn’t go as planned.'
- B. Assure the client by stating, 'At least you know you have a healthy baby.'
- C. Encourage the client by suggesting, 'Maybe next time you can have a vaginal delivery.'
- D. Provide information by saying, 'You can resume sexual relations sooner than if you had delivered vaginally.'
Correct answer: A: 'It sounds like you are feeling sad that things didn’t go as planned.'
Rationale: The correct response is to acknowledge and validate the client's feelings of disappointment. This empathetic approach demonstrates understanding and support for the client's emotional state, fostering a therapeutic nurse-client relationship. Options B, C, and D do not address the client's emotional needs or provide appropriate support in this situation.
3. A healthcare professional is reviewing the arterial blood gas results for a client in the ICU who has kidney failure and determines the client has respiratory acidosis. Which of the following findings should the healthcare professional expect?
- A. Widened QRS complexes
- B. Hyperactive deep tendon reflexes
- C. Bounding peripheral pulses
- D. Warm, flushed skin
Correct answer: Widened QRS complexes
Rationale: Respiratory acidosis is characterized by an increase in carbon dioxide levels in the blood, leading to acidosis. This condition can affect the heart's electrical conduction system, resulting in widened QRS complexes on an electrocardiogram (ECG). Hyperactive deep tendon reflexes, bounding peripheral pulses, and warm, flushed skin are not typically associated with respiratory acidosis.
4. A newborn's mother is positive for the hepatitis B surface antigen. Which of the following should the infant receive?
- A. Hepatitis B immune globulin at 1 week followed by hepatitis B vaccine monthly for 6 months
- B. Hepatitis B vaccine monthly until the newborn tests negative for the hepatitis B surface antigen
- C. Hepatitis B immune globulin and hepatitis B vaccine within 12 hr of birth
- D. Hepatitis B vaccine at 24 hr followed by hepatitis B immune globulin every 12 hr for 3 days
Correct answer: Hepatitis B immune globulin and hepatitis B vaccine within 12 hr of birth
Rationale: In the scenario where a newborn's mother is positive for hepatitis B surface antigen, the infant should receive both hepatitis B immune globulin and hepatitis B vaccine within 12 hours of birth. This is crucial to provide passive and active immunity against the Hepatitis B virus. Hepatitis B immune globulin provides immediate protection by giving passive immunity, while the vaccine stimulates active immunity in the infant. Administering both within 12 hours of birth is important to prevent vertical transmission of the virus.
5. A healthcare provider is preparing to administer an injection of Rho (D) immunoglobulin. The provider should understand that the purpose of this injection is to prevent which of the following newborn complications?
- A. Hydrops fetalis
- B. Hypobilirubinemia
- C. Biliary atresia
- D. Transient clotting difficulties
Correct answer: Hydrops fetalis
Rationale: Rho (D) immunoglobulin is given to Rh-negative individuals to prevent hemolytic disease of the newborn (HDN) caused by Rh incompatibility between the mother and the fetus. If an Rh-negative mother carries an Rh-positive fetus, there is a risk of sensitization during pregnancy or childbirth. Sensitization can lead to the production of antibodies that may attack Rh-positive red blood cells in future pregnancies, potentially causing severe hemolytic disease in the newborn, including complications like hydrops fetalis. Hydrops fetalis is a condition characterized by severe edema and fetal organ enlargement due to severe anemia and heart failure in the fetus.
