1. How will a ventricular septal defect affect blood flow?

• A. Blood will shunt left to right, causing increased pulmonary flow and no cyanosis.
• B. Blood will shunt right to left, causing decreased pulmonary flow and cyanosis.
• C. No shunting occurs due to high pressure in the left ventricle.
• D. Increased pressure in the left atrium hinders the circulation of oxygenated blood in the circulating volume.

Correct answer: A

Rationale: A ventricular septal defect allows blood to shunt left to right, leading to increased pulmonary flow. This results in oxygenated blood mixing with deoxygenated blood, causing no cyanosis as the mixed blood is still oxygenated. The shunting from left to right overloads the pulmonary circulation, leading to increased pulmonary flow. Choice B is incorrect because blood does not shunt right to left in a ventricular septal defect. Choice C is incorrect as shunting does occur due to the pressure differences between the ventricles. Choice D is incorrect because the defect affects the ventricles, not the atrium, and does not hinder the circulation of oxygenated blood in the circulating volume.

2. 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.

3. Fred is a 12-year-old boy diagnosed with pneumococcal pneumonia. Which of the following would Nurse Nica expect to assess?

• A. Mild cough
• B. Slight fever
• C. Chest pain
• D. Bulging fontanel

Correct answer: C

Rationale: Chest pain is a common symptom seen in patients with pneumococcal pneumonia. It can result from inflammation of the pleura or irritation of the diaphragm due to the infection. While cough and fever are also common symptoms, chest pain is particularly significant in pneumonia cases as it can be a distressing symptom for the patient and may indicate complications or severity of the infection. Bulging fontanel, on the other hand, is more indicative of conditions affecting infants and is not typically associated with pneumococcal pneumonia in a 12-year-old boy.

4. Which of the following is an indication of lower respiratory infection?

• A. Cough
• B. Fever
• C. Inability to lie supine
• D. Shortness of breath

Correct answer: C

Rationale: Inability to lie supine is a significant indication of lower respiratory infection. This symptom often occurs due to breathing difficulties and discomfort experienced by individuals with lower respiratory infections, such as pneumonia or bronchitis. It can be caused by lung inflammation, consolidation, or fluid buildup in the lungs, making lying flat uncomfortable or difficult. Monitoring a patient's ability to lie flat can provide valuable information about the severity and progression of a lower respiratory infection.

5. A mother of a 6-year-old actively playing child, diagnosed with type 1 diabetes mellitus a year ago, calls a clinic nurse and reports that the child has been sick. She checked the child's urine, which was positive for ketones. What should the nurse instruct the mother to do?

• A. Administer an additional dose of regular insulin
• B. Come to the clinic immediately
• C. Encourage the child to drink liquids
• D. Hold the next dose of insulin

Correct answer: C

Rationale: Encouraging the child to drink liquids is essential in managing ketones in urine. Increased fluid intake can help prevent dehydration and aid in flushing out ketones, which is crucial in managing diabetic ketoacidosis, a serious complication of uncontrolled diabetes.
