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. Which of the following is a more reliable indicator of perfusion in children than in adults?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Capillary refill

Correct answer: D

Rationale: Capillary refill is a more reliable indicator of perfusion in children than in adults. This is because children have more compliant vessels, making capillary refill a more sensitive indicator of perfusion status in this population. In contrast, while blood pressure, heart rate, and respiratory rate are important indicators, they may not be as reliable in children as capillary refill. Blood pressure can be affected by various factors such as anxiety or pain, heart rate can be influenced by emotions or temperature, and respiratory rate may vary with activity levels. Therefore, capillary refill is preferred in children for a more accurate assessment of perfusion.

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. When responding to a call for a 2-year-old child who fell from a second-story window, with the mechanism of injury and the age of the patient in mind, you should suspect that the primary injury occurred to the child's:

• A. chest.
• B. head.
• C. lower extremities.
• D. abdomen.

Correct answer: B

Rationale: In a scenario where a young child falls from a significant height like a second-story window, the primary injury is more likely to be to the head. This is because young children have proportionately larger head sizes compared to their body, making them more susceptible to head injuries in such falls. The chest (Choice A), lower extremities (Choice C), and abdomen (Choice D) are less likely to sustain the primary injury in this scenario, as the impact of the fall and the child's anatomy predispose the head to be the most affected area.
