Maternity HESI 2023 Quizlet
1. A 6-week-old infant diagnosed with pyloric stenosis has recently developed projectile vomiting. Which assessment finding indicates to the nurse that the infant is becoming dehydrated?
- A. Weak cry without tears.
- B. Bulging fontanel.
- C. Visible peristaltic wave.
- D. Palpable mass in the right upper quadrant.
Correct answer: A
Rationale: In infants, a weak cry without tears is a classic sign of dehydration. Tears are produced by the lacrimal glands, and reduced tear production is a result of dehydration. This assessment finding should alert the nurse to the infant's dehydration status, requiring prompt intervention to prevent further complications.
2. A client with pneumonia has arterial blood gases levels at: pH 7.33; PaCO2 49 mm/Hg; HCO3 25 mEq/L; PaO2 95. What intervention should the nurse implement based on these results?
- A. Institute coughing and deep breathing protocols.
- B. Administer oxygen via nasal cannula.
- C. Prepare for intubation and mechanical ventilation.
- D. Increase IV fluids to improve hydration.
Correct answer: A
Rationale: The ABG results indicate respiratory acidosis due to an elevated PaCO2 (49 mm/Hg), indicating hypoventilation. The appropriate intervention for respiratory acidosis is to improve ventilation. Coughing and deep breathing protocols can help the client to effectively ventilate and improve gas exchange. Administering oxygen via nasal cannula (Choice B) may be necessary in respiratory distress situations, but addressing the underlying cause of hypoventilation is crucial. Intubation and mechanical ventilation (Choice C) are not the first-line interventions for uncomplicated respiratory acidosis. Increasing IV fluids (Choice D) does not directly address the respiratory acidosis present in this scenario.
3. When performing a health history on a patient who is to begin receiving a thiazide diuretic to treat heart failure, the nurse will be concerned about a history of which condition?
- A. Asthma
- B. Glaucoma
- C. Gout
- D. Hypertension
Correct answer: C
Rationale: Thiazide diuretics block uric acid secretion, leading to elevated levels that can contribute to gout. Therefore, patients with a history of gout should take thiazide diuretics with caution. Asthma (Choice A), Glaucoma (Choice B), and Hypertension (Choice D) are not directly contraindicated with thiazide diuretics, making choices A, B, and D incorrect.
4. An S3 heart sound is auscultated in a client in her third trimester of pregnancy. What intervention should the nurse take?
- A. Perform a 12-lead electrocardiogram
- B. Document in the client's record
- C. Notify the healthcare provider immediately
- D. Assess for signs of heart failure
Correct answer: B
Rationale: An S3 heart sound is often a normal finding in pregnant women due to increased blood volume and cardiac output. The nurse should document the finding as part of the routine assessment unless accompanied by other abnormal symptoms. Performing a 12-lead electrocardiogram (Choice A) is unnecessary for a normal S3 heart sound in pregnancy. Notifying the healthcare provider immediately (Choice C) is premature and may lead to unnecessary interventions. Assessing for signs of heart failure (Choice D) is not indicated as an isolated S3 heart sound is typically benign in pregnancy.
5. A one-day-old neonate develops a cephalohematoma. The nurse should closely assess this neonate for which common complication?
- A. Jaundice.
- B. Poor feeding.
- C. Brain injury.
- D. Hypoglycemia.
Correct answer: A
Rationale: A cephalohematoma is a collection of blood between the skull and the periosteum. As the blood breaks down, there is an increased risk of jaundice due to the release of bilirubin from the breakdown of red blood cells. Jaundice is a common complication associated with cephalohematoma in neonates. Therefore, the nurse should closely monitor the neonate for signs of jaundice and manage it accordingly.
