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: A
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 nurse in an antepartum unit is triaging clients. Which of the following clients should the nurse see first?
- A. A client who is at 38 weeks of gestation and reports a cough and fever
- B. A client who has missed a period and reports vaginal spotting
- C. A client who is at 14 weeks of gestation and reports nausea and vomiting
- D. A client who is at 28 weeks of gestation and reports of painless vaginal bleeding
Correct answer: D
Rationale:
3. A client who is 2 hours postpartum following a cesarean birth has a history of thromboembolic disease. Which of the following nursing interventions should be included in the plan of care?
- A. Apply warm, moist heat to the client's lower extremities.
- B. Massage the client's posterior lower legs.
- C. Place pillows under the client's knees when resting in bed.
- D. Have the client ambulate.
Correct answer: D
Rationale: The correct intervention for a client who is 2 hours postpartum following a cesarean birth with a history of thromboembolic disease is to have the client ambulate. Early ambulation is crucial in preventing complications such as deep vein thrombosis in postpartum clients. Applying warm, moist heat, massaging the legs, or placing pillows under the knees do not directly address the risk of thromboembolic disease in this scenario.
4. When caring for a newborn with macrosomia born to a mother with diabetes mellitus, which newborn complication should the nurse prioritize care for?
- A. Hypoglycemia
- B. Hypomagnesemia
- C. Hyperbilirubinemia
- D. Hypocalcemia
Correct answer: A
Rationale: In newborns of diabetic mothers with macrosomia, hypoglycemia is the priority focus of care due to the risk of developing low blood sugar levels after birth. Infants born to diabetic mothers are at risk of hypoglycemia because they have been exposed to high glucose levels in utero and produce high levels of insulin. Hypoglycemia can lead to serious complications if not promptly identified and managed, making it crucial for nurses to closely monitor blood glucose levels and provide necessary interventions to prevent adverse outcomes.
5. A client at 10 weeks of gestation reports abdominal pain and moderate vaginal bleeding. The tentative diagnosis is inevitable abortion. Which of the following nursing interventions should be included in the plan of care?
- A. Administer oxygen via nasal cannula
- B. Offer option to view products of conception
- C. Instruct the client to increase potassium-rich foods in the diet
- D. Maintain the client on bed rest
Correct answer: B
Rationale: Offering the client the option to view products of conception after an inevitable abortion can provide closure and support the grieving process. It allows the client to have a visual confirmation of the pregnancy loss, which can aid in emotional healing. Administering oxygen is not a priority in this scenario as there is no indication of respiratory distress. Instructing the client to increase potassium-rich foods is not directly related to managing an inevitable abortion. Bed rest may be recommended, but offering the option to view products of conception is a more appropriate intervention at this time.
