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. The healthcare provider is teaching a new mother how to care for her newborn's umbilical cord. Which instruction should be included?

• A. Keep the cord dry and exposed to air
• B. Clean the cord with alcohol at every diaper change
• C. Cover the cord with a sterile dressing
• D. Submerge the cord in water during baths

Correct answer: A

Rationale: Keeping the umbilical cord dry and exposed to air is the correct instruction because it promotes faster healing. Moisture can delay the healing process and increase the risk of infection. Cleaning the cord with alcohol at every diaper change or covering it with a sterile dressing can actually impede the healing process by preventing airflow. Submerging the cord in water during baths is not recommended as it can introduce moisture and increase the risk of infection.

3. Which of the following signs or symptoms is more common in children than adults following an isolated head injury?

• A. Changes in pupillary reaction
• B. Tachycardia and diaphoresis
• C. Nausea and vomiting
• D. Altered mental status

Correct answer: C

Rationale: Nausea and vomiting are more common in children than adults following an isolated head injury. Children often present with gastrointestinal symptoms like nausea and vomiting after a head injury due to differences in physiological responses compared to adults.

4. Atta, who weighs 20kg, has been prescribed amoxicillin 500 mg b.i.d. The drug information indicates a daily dose of amoxicillin at 50 mg/kg/day in two divided doses. What is the safest dose in milligrams for this child?

• A. 1000 mg
• B. 750 mg
• C. 500 mg
• D. 250 mg

Correct answer: A

Rationale: To calculate the safest dose of amoxicillin for Atta, we multiply the weight (20kg) by the daily dose (50 mg/kg/day) which equals 1000 mg/day. Since the dose is to be given in two divided doses, the safest dose for each administration would be 500 mg. Therefore, the correct answer is 1000 mg, as it aligns with the prescribed dose for this child based on weight and dosing guidelines. Choice B, 750 mg, is incorrect as it does not match the calculated daily dose. Choice C, 500 mg, is incorrect as it represents the safest dose for each administration, not the total daily dose. Choice D, 250 mg, is incorrect as it is below the calculated daily dose required for the child.

5. You arrive at a residence shortly after a 4-year-old boy experienced an apparent febrile seizure. The child is alert and crying. His skin is flushed, hot, and moist. His mother tells you that the seizure lasted about 2 minutes. You should:

• A. provide supportive care and transport.
• B. give him acetaminophen or ibuprofen.
• C. begin rapid cooling measures at once.
• D. allow the mother to take her child to the doctor.

Correct answer: A

Rationale: After a febrile seizure, the recommended course of action is to provide supportive care and transport the child to a medical facility. Supportive care may include ensuring a safe environment, monitoring the child, and seeking medical evaluation to determine the underlying cause of the seizure and appropriate management.
