Nursing Elites

1. Sometimes, people with congestive heart failure develop arrhythmias of the heart. These irregular rhythms can be conducive to developing a blood clot. Physicians frequently treat people with 'blood thinning' medicines that require regulation of the density of the blood. Which of these is the name for a blood-thinner?

• A. Erythromycin
• B. Tetracycline
• C. Warfarin
• D. Amoxicillin

Correct answer: C

Rationale: Warfarin is a medication commonly used as a blood thinner to prevent blood clot formation. It works by inhibiting the clotting factors in the blood, thereby reducing the risk of clot formation and helping in the management of conditions like congestive heart failure and arrhythmias. Choices A, B, and D are antibiotics and do not have blood-thinning properties like Warfarin.

2. A new parent reports to the nurse that the baby looks cross-eyed several times a day. The nurse teaches the parents that this finding should resolve in how long?

• A. 2 months
• B. 2 weeks
• C. 1 year
• D. 4 months

Correct answer: D

Rationale: Transient strabismus, causing the baby to look cross-eyed, is due to poor neuromuscular control of the eye muscles. This condition typically resolves on its own within 3 to 4 months as the infant's neuromuscular control improves. Parents should be reassured that this is a common and temporary issue in infants. Choice A is incorrect as it is too long for the resolution of transient strabismus. Choice B is incorrect as 2 weeks is too short for resolution. Choice C is incorrect as 1 year is too long for transient strabismus to resolve.

3. Which of the following statements regarding febrile seizures in children is correct?

• A. They can occur even after a child has had a fever for longer than 24 hours.
• B. They can be caused by viral or bacterial meningitis.
• C. They do not typically occur on the first day of a fever.
• D. They typically last less than 15 minutes and often do not have a postictal phase.

Correct answer: D

Rationale: The correct answer is D. Febrile seizures in children typically last less than 15 minutes and often do not have a postictal phase, meaning there is usually no prolonged recovery period or confusion after the seizure. They are commonly associated with the rapid rise in body temperature at the onset of a fever, rather than the duration of the fever itself. Choices A, B, and C are incorrect because febrile seizures can occur even after a child has had a fever for longer than 24 hours, they can be caused by viral or bacterial meningitis, and they do not have a typical pattern of occurring on the first day of a fever.

4. Why should small children ride in the backseat of a vehicle?

• A. They are much less likely to be ejected from the vehicle.
• B. The back of the front seat will provide a cushion during a crash.
• C. They can experience severe injury or death if the airbag deploys.
• D. Their legs are highly prone to injury from striking the dashboard.

Correct answer: C

Rationale: Small children should ride in the backseat of a vehicle primarily to avoid severe injury or death that may occur if the airbag deploys. In the event of a crash, the force of an airbag deployment can be dangerous for a child seated in the front seat. Placing them in the backseat reduces the risk of serious harm from airbag impact and is a safer seating position for young passengers.

5. The nurse is preparing to administer vitamin K to a newborn. The mother asks why this injection is necessary. What is the nurse's best response?

• A. It helps the baby's liver function properly.
• B. It prevents bleeding disorders in the newborn.
• C. It boosts the baby's immune system.
• D. It promotes the baby's growth and development.

Correct answer: B

Rationale: The correct answer is B. Vitamin K is administered to newborns to prevent bleeding disorders since they have low levels of vitamin K, which is essential for blood clotting. By providing this injection, the nurse ensures that the newborn has an adequate supply of vitamin K to support proper blood clotting and prevent potential bleeding complications. Choices A, C, and D are incorrect because vitamin K's primary role in newborns is related to blood clotting and preventing bleeding, not liver function, immune system, or growth and development.
