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. When discussing heart conditions, a healthcare provider explains a condition in which the lungs retain extra fluid due to left ventricular impairment. What is this condition?

• A. Whooping cough
• B. Pneumonia
• C. Asthma
• D. Pulmonary edema

Correct answer: D

Rationale: Pulmonary edema is the correct answer. It is a condition characterized by the retention of extra fluid in the lungs, often due to left ventricular impairment. This fluid buildup can lead to symptoms such as shortness of breath, coughing, and difficulty breathing. Whooping cough (Choice A), pneumonia (Choice B), and asthma (Choice C) are not conditions related to the retention of fluid in the lungs due to left ventricular impairment. Whooping cough is a bacterial respiratory infection, pneumonia is an infection that inflames the air sacs in one or both lungs, and asthma is a chronic respiratory condition characterized by airway inflammation and constriction.

3. Upon assessing a newborn immediately after delivery, you note that the infant is breathing spontaneously and has a heart rate of 80 beats/min. What is the MOST appropriate initial management for this newborn?

• A. Assess the newborn's skin condition and color.
• B. Initiate positive-pressure ventilations.
• C. Start chest compressions and contact medical control.
• D. Provide blow-by oxygen with oxygen tubing.

Correct answer: B

Rationale: In a newborn with a heart rate below 100 beats/min, the most appropriate initial management is to initiate positive-pressure ventilations. This helps support the newborn's respiratory effort and oxygenation in the setting of a low heart rate, ensuring adequate oxygen supply to vital organs. Assessing the skin condition and color, starting chest compressions, or providing blow-by oxygen are not the priority in this scenario where respiratory support is crucial.

4. What should the nurse include in the insulin administration instruction for the parents of a child being discharged on insulin?

• A. Insert the needle and aspirate before injecting
• B. Inject insulin into the extremity to be exercised to improve absorption
• C. The muscles in the abdomen and thigh are the easiest for self-administration
• D. Clean the injection site with soap and water and avoid alcohol

Correct answer: C

Rationale: The correct answer is C because the muscles in the abdomen and thigh are the most suitable areas for self-administration of insulin due to consistent absorption. Choices A and B are incorrect as aspirating before injecting insulin is unnecessary, and injecting into an extremity to be exercised does not enhance absorption. Choice D is incorrect as alcohol should be used to clean the injection site instead of soap and water, which can cause skin irritation.

5. The nurse is preparing to administer erythromycin eye ointment to a newborn. The mother asks why this is necessary. What is the nurse's best response?

• A. It helps to prevent eye infections caused by bacteria in the birth canal.
• B. It protects the baby's eyes from bright lights in the delivery room.
• C. It prevents the development of jaundice.
• D. It helps the baby see more clearly after birth.

Correct answer: A

Rationale: Erythromycin eye ointment is administered to newborns to prevent eye infections caused by bacteria present in the birth canal. This ointment does not have a direct correlation with protecting the baby's eyes from bright lights, preventing jaundice, or improving the baby's vision clarity post-birth.
