HESI Maternal Newborn
1. A primiparous woman presents in labor with the following labs: hemoglobin 10.9 g/dL, hematocrit 29%, hepatitis surface antigen positive, Group B Streptococcus positive, and rubella non-immune. Which intervention should the nurse implement?
- A. Transfuse 2 units of packed red blood cells.
- B. Give measles, mumps, rubella vaccine 0.5 mL.
- C. Administer ampicillin 2 grams intravenously.
- D. Inject hepatitis B immune globulin 0.5 milliliters.
Correct answer: C
Rationale: The correct intervention in this scenario is to administer ampicillin 2 grams intravenously. This is crucial to prevent Group B Streptococcus infection in the newborn during delivery. Option A, transfusing packed red blood cells, is not indicated based on the hemoglobin and hematocrit levels provided. Option B, giving measles, mumps, rubella vaccine, is not necessary at this time. Option D, injecting hepatitis B immune globulin, is not appropriate for the conditions presented in the question.
2. A client who had surgery yesterday is becoming increasingly anxious. The client’s respiratory rate has increased to 38 breaths/minute. The client has a nasogastric tube to low intermittent suction with 500 ml of yellow-green drainage over the last four hours. The client's arterial blood gases (ABGs) indicate a decreased CO2 and an increased serum pH. Which serum laboratory value should the nurse monitor first?
- A. Electrolytes.
- B. Creatinine.
- C. Blood urea nitrogen.
- D. Glucose.
Correct answer: A
Rationale: The correct answer is A, Electrolytes. In this scenario, the client is at risk for metabolic alkalosis due to the loss of gastric secretions through the nasogastric tube. Monitoring electrolytes is crucial to assess the levels of sodium, potassium, chloride, and bicarbonate, which are important in maintaining the acid-base balance of the body. Changes in these electrolyte levels can provide valuable information about the client's fluid status and acid-base balance. Creatinine, blood urea nitrogen, and glucose levels are important parameters to monitor in different situations but are not the priority in this case of potential metabolic alkalosis.
3. A client with a history of chronic back pain is prescribed oxycodone for pain management. What is the most important instruction the nurse should provide?
- A. Take the medication with food to reduce stomach upset
- B. Avoid operating heavy machinery while taking this medication
- C. Increase physical activity to enhance pain relief
- D. Report any signs of respiratory depression immediately
Correct answer: D
Rationale: The correct answer is D: 'Report any signs of respiratory depression immediately.' Respiratory depression is a severe side effect of opioids like oxycodone and can be life-threatening. It is crucial for the nurse to instruct the client to report any signs such as slow or shallow breathing, difficulty breathing, or confusion. Choice A is incorrect as taking oxycodone with or without food does not significantly affect its efficacy. Choice B is incorrect because avoiding driving is important due to the potential impairment caused by oxycodone, but reporting respiratory depression is more critical. Choice C is incorrect as increasing physical activity may not always be suitable for individuals with chronic back pain and is not directly related to preventing respiratory depression.
4. What clinical manifestation of tetralogy of Fallot should the nurse expect when caring for children with this diagnosis?
- A. Slow respirations
- B. Clubbing of fingers
- C. Decreased RBC counts
- D. Subcutaneous hemorrhages
Correct answer: B
Rationale: Clubbing of fingers is a common manifestation in children with tetralogy of Fallot due to chronic hypoxia. Clubbing occurs as a result of long-standing decreased oxygen levels in the blood, leading to changes in the fingertips. Slow respirations (Choice A) are not typically a direct clinical manifestation of tetralogy of Fallot. While decreased RBC counts (Choice C) may occur due to chronic hypoxia, they are not a primary manifestation specific to tetralogy of Fallot. Subcutaneous hemorrhages (Choice D) are not a common clinical manifestation associated with tetralogy of Fallot.
5. Following an amniocentesis, a nurse is caring for a client. The nurse should observe the client for which of the following complications?
- A. Hyperemesis
- B. Proteinuria
- C. Hypoxia
- D. Hemorrhage
Correct answer: D
Rationale: After an amniocentesis, the nurse should monitor the client for potential complications, with hemorrhage being a significant concern due to the invasive nature of the procedure. Hyperemesis (severe vomiting), proteinuria (excessive protein in the urine), and hypoxia (low oxygen levels) are not typically associated with amniocentesis and are less likely to occur compared to hemorrhage, which is a more common complication that requires prompt recognition and intervention.
