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. When drawing blood from the diabetic patient for a glycosylated hemoglobin (HBA1c) test, the nurse explains to the woman that the test is used to determine:

• A. The highest glucose level in the past week.
• B. Her insulin levels.
• C. Glucose levels over the past three months.
• D. Her usual fasting glucose level.

Correct answer: C

Rationale: The glycosylated hemoglobin (HBA1c) test reflects the average blood sugar levels over the past three months. It provides a more comprehensive view of the individual's glucose control compared to a single point-in-time measurement like a fasting glucose level or the highest glucose level in the past week. Choice A is incorrect because it focuses on a single high glucose level rather than the overall control over a period. Choice B is incorrect as HBA1c is not a test for insulin levels. Choice D is incorrect as the HBA1c test does not reflect a single fasting glucose level but rather an average over a more extended period.

3. Are most children with hypertension asymptomatic?

• A. TRUE
• B. FALSE
• C.
• D.

Correct answer: A

Rationale: The statement is true. In many cases, children with hypertension do not show any symptoms, making it challenging to diagnose them. Regular blood pressure checks are crucial to detect hypertension early, as it can have serious health implications if left untreated. Choice B is incorrect because most children with hypertension do not exhibit symptoms, hence being asymptomatic. Choices C and D are empty as they do not provide additional options.

4. Which of the following is NOT an infectious cause of diarrheal diseases?

• A. Allergy
• B. Bacterial
• C. Parasitic
• D. Viral

Correct answer: A

Rationale: Allergy is the correct answer as it is a non-infectious cause of diarrheal diseases. While bacterial, parasitic, and viral infections can lead to diarrhea by affecting the gastrointestinal tract, allergies are immune system reactions triggered by specific substances and are not caused by infectious agents. Bacterial, parasitic, and viral infections are known to cause infectious diarrhea, making choices B, C, and D incorrect.

5. You are called to a local park for a 7-year-old boy with respiratory distress. During your assessment, you find that the patient is wheezing and has widespread hives and facial edema. What should you suspect has occurred?

• A. Poison oak exposure
• B. Allergic reaction
• C. Heat illness
• D. Acute asthma attack

Correct answer: B

Rationale: The presentation of wheezing, widespread hives, and facial edema is consistent with an allergic reaction. These symptoms indicate a systemic response to an allergen, triggering respiratory distress and skin manifestations.
