ATI Maternal Newborn Proctored Exam
1. A client with chronic kidney disease has arterial blood gas values being reviewed by a nurse. Which of the following sets of values should the nurse expect?
- A. pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg
- B. pH 7.30, HCO3- 26 mEq/L, PaCO2 50 mm Hg
- C. pH 7.50, HCO3- 20 mEq/L, PaCO2 32 mm Hg
- D. pH 7.55, HCO3- 30 mEq/L, PaCO2 31 mm Hg
Correct answer: A
Rationale: In chronic kidney disease, metabolic acidosis is common due to impaired kidney function leading to reduced bicarbonate excretion. The correct values indicating metabolic acidosis in this scenario are a low pH (acidosis), low bicarbonate (HCO3-) level, and low PaCO2 (compensation through respiratory alkalosis). Therefore, the expected values for a client with chronic kidney disease would be pH 7.25, HCO3- 19 mEq/L, PaCO2 30 mm Hg, as depicted in choice A.
2. During the admission assessment of a client at 38 weeks of gestation with severe preeclampsia, what would the nurse expect as a finding?
- A. Tachycardia
- B. Absence of clonus
- C. Polyuria
- D. Report of headache
Correct answer: D
Rationale: Severe preeclampsia is characterized by hypertension and proteinuria after 20 weeks of gestation. Headache is a common symptom in clients with severe preeclampsia due to cerebral edema or vasospasm. Tachycardia (Choice A) is not typically associated with severe preeclampsia. Clonus (Choice B) is a sign of hyperactive reflexes, often seen in clients with severe preeclampsia. Polyuria (Choice C) is not a typical finding in clients with severe preeclampsia.
3. A client who is 4 hours postpartum following a vaginal delivery is being assessed by a nurse. Which of the following findings should the nurse identify as the priority?
- A. Saturated perineal pad in 30 minutes
- B. Deep tendon reflexes 4+
- C. Fundus at the level of the umbilicus
- D. Approximated edges of episiotomy
Correct answer: A
Rationale: In a client who is 4 hours postpartum, a saturated perineal pad within 30 minutes is a priority finding as it may indicate excessive postpartum bleeding (hemorrhage), which requires immediate intervention to prevent further complications such as hypovolemic shock. Deep tendon reflexes being 4+ is within normal limits postpartum. The fundus at the level of the umbilicus is an expected finding at this time frame, indicating proper involution of the uterus. Approximated edges of an episiotomy suggest proper healing.
4. When admitting a client at 33 weeks of gestation with a diagnosis of placenta previa, which action should the nurse prioritize?
- A. Monitor vaginal bleeding
- B. Administer glucocorticoids
- C. Insert an IV catheter
- D. Apply an external fetal monitor
Correct answer: D
Rationale: Placenta previa is a condition where the placenta partially or completely covers the cervix, leading to potential bleeding. When admitting a client with placenta previa, the priority is to assess the fetal well-being. Applying an external fetal monitor helps in continuous monitoring of the fetal heart rate and ensures timely detection of any distress or changes in the fetal status, which is crucial in managing this condition. While monitoring vaginal bleeding is important, identifying fetal well-being takes precedence in this situation.
5. A client is admitted to the emergency room with a respiratory rate of 7/min. Arterial blood gases (ABG) reveal the following values. Which of the following is an appropriate analysis of the ABGs? pH 7.22, PaCO2 68 mm Hg, Base excess -2, PaO2 78 mm Hg, Saturation 80%, Bicarbonate 26 mEq/L
- A. Respiratory acidosis
- B. Metabolic acidosis
- C. Metabolic alkalosis
- D. Respiratory alkalosis
Correct answer: A
Rationale: The ABG values provided indicate respiratory acidosis. In respiratory acidosis, there is an increase in PaCO2 above the normal range (35-45 mm Hg) leading to a decrease in pH (<7.35). In this case, the pH is 7.22 (below normal) with an elevated PaCO2 of 68 mm Hg. The other values do not suggest metabolic acidosis (which would typically show low bicarbonate levels) or metabolic alkalosis. Therefore, the correct interpretation of the ABGs is respiratory acidosis.
