Nursing Elites

1. An infant with tetralogy of Fallot becomes acutely cyanotic and hyperneic. Which action should the nurse implement first?

• A. Place the infant in a knee-chest position.
• B. Administer morphine sulfate.
• C. Start intravenous fluids.
• D. Provide 100% oxygen by face mask.

Correct answer: A

Rationale: In a tetralogy of Fallot situation, placing the infant in a knee-chest position is the initial priority to help increase systemic vascular resistance, which reduces the right-to-left shunt and improves oxygenation. This position can assist in optimizing oxygen levels before considering other interventions. Administering morphine sulfate (choice B) is not the first-line treatment for tetralogy of Fallot crisis. Starting intravenous fluids (choice C) may be necessary but is not the priority in this situation. Providing 100% oxygen by face mask (choice D) may not fully address the underlying issue of decreased systemic vascular resistance that leads to cyanosis in tetralogy of Fallot.

2. A client at 32 weeks gestation is hospitalized with severe pregnancy-induced hypertension (PIH), and magnesium sulfate is prescribed to control the symptoms. Which assessment finding indicates the therapeutic drug level has been achieved?

• A. 4+ reflexes
• B. Urinary output of 50 ml per hour
• C. A decrease in respiratory rate from 24 to 16
• D. A decreased body temperature

Correct answer: C

Rationale: A decrease in respiratory rate from 24 to 16 indicates that magnesium sulfate is effectively reducing central nervous system irritability, a desired therapeutic effect. This decrease in respiratory rate signifies that the drug has reached a therapeutic level to control symptoms of severe pregnancy-induced hypertension. Choices A, B, and D are incorrect because 4+ reflexes, urinary output, and body temperature are not direct indicators of achieving a therapeutic level of magnesium sulfate for controlling PIH symptoms.

3. The client is 30 weeks pregnant and experiencing preterm labor. Which medication should the nurse anticipate administering to promote fetal lung maturity?

• A. Betamethasone (Celestone).
• B. Magnesium sulfate.
• C. Terbutaline (Brethine).
• D. Ampicillin.

Correct answer: A

Rationale: Betamethasone (Celestone) is the medication of choice to promote fetal lung maturity in cases of preterm labor. It helps accelerate surfactant production in the fetal lungs, reducing the risk of respiratory distress syndrome. Administering betamethasone to the mother can improve the baby's lung function and overall outcome if preterm birth occurs. Magnesium sulfate is commonly used to prevent seizures in preeclampsia or eclampsia. Terbutaline is a tocolytic agent used to suppress preterm labor contractions. Ampicillin is an antibiotic used for various bacterial infections but does not promote fetal lung maturity.

4. A client is admitted to the postpartum unit and tells the nurse she had rheumatic fever as a child, which resulted in some 'heart damage'. The nurse knows that this client is at particular risk for developing heart failure during the immediate postpartum period. Based on the client's history, which nursing problem has the highest priority?

• A. Nausea and vomiting.
• B. Risk for infection.
• C. Sleep deprivation.
• D. Fluid volume excess.

Correct answer: D

Rationale: Fluid volume excess is a priority concern in this client, as heart damage from rheumatic fever can impair the heart's ability to manage increased blood volume postpartum, leading to potential heart failure. Monitoring and managing fluid volume status are crucial to prevent complications in this high-risk client. Choices A, B, and C are not the highest priority in this situation. Nausea and vomiting, risk for infection, and sleep deprivation are important but do not pose an immediate threat to the client's physiologic stability compared to the risk of heart failure due to fluid volume excess.

5. A mother calls the school nurse to report that her preschool-aged child was bitten by a tick during a school outing last week. The mother removed the tick and flushed it down the toilet. What action should the school nurse take?

• A. Refer the mother to the Centers for Disease Control and Prevention.
• B. Report the incident to the school principal.
• C. Culture the bite site when the child returns to school.
• D. Schedule a test for Lyme disease if a rash appears.

Correct answer: D

Rationale: The correct action to take in this situation is to schedule a test for Lyme disease if a rash appears. Lyme disease can be transmitted through tick bites, and a rash is a common early symptom of the disease. Testing for Lyme disease is crucial for timely diagnosis and treatment to prevent complications. Referring the mother to the Centers for Disease Control and Prevention (Choice A) is not necessary at this point, as immediate testing for Lyme disease is more appropriate. Reporting the incident to the school principal (Choice B) is not the most direct action to address the potential health concern. Culturing the bite site when the child returns to school (Choice C) may not be as effective as scheduling a test for Lyme disease if a rash appears, as the latter is a more specific diagnostic measure for Lyme disease.
