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 healthcare professional is reviewing the laboratory values of a client who has respiratory acidosis. Which of the following findings should the healthcare professional expect?
- A. HCO3- 30 mEq/L
- B. PaCO2 50 mm Hg
- C. pH 7.45
- D. Potassium 3.3 mEq/L
Correct answer: B
Rationale: In respiratory acidosis, the primary disturbance is an increase in PaCO2 levels above the normal range of 35-45 mm Hg. Option B, PaCO2 50 mm Hg, indicates an elevated partial pressure of carbon dioxide, which is consistent with respiratory acidosis. Options A, C, and D are not directly indicative of respiratory acidosis. HCO3- (Option A) is more related to metabolic acidosis or alkalosis, pH (Option C) is within the normal range indicating no acid-base imbalance, and potassium (Option D) levels are not specific to respiratory acidosis.
3. 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.
4. A nurse in the antepartum unit is caring for a client who is at 36 weeks of gestation and has pregnancy-induced hypertension. Suddenly, the client reports continuous abdominal pain and vaginal bleeding. The nurse should suspect which of the following comp
- A. Placenta previa
- B. Prolapsed cord
- C. Incompetent cervix
- D. Abruptio placentae
Correct answer: D
Rationale:
5. A client at 22 weeks of gestation with uncontrolled gestational diabetes mellitus may require medication. Which of the following medications would the provider likely prescribe?
- A. Acarbose
- B. Repaglinide
- C. Glyburide
- D. Glipizide
Correct answer: C
Rationale: Glyburide is commonly prescribed for gestational diabetes mellitus when diet and exercise are insufficient to control blood sugar levels. It is considered safe and effective during pregnancy, making it a suitable choice for managing diabetes in pregnant individuals. Acarbose, Repaglinide, and Glipizide are not typically recommended for use in pregnancy due to potential risks to the fetus.
