1. At what age is binocularity, the ability to fixate on one visual field with both eyes simultaneously, typically achieved?

• A. 1 month
• B. 3 to 4 months
• C. 6 to 8 months
• D. 12 months

Correct answer: B

Rationale: Binocularity, the ability to fixate on one visual field with both eyes simultaneously, is typically achieved by the age of 3 to 4 months. Achieving binocularity at 1 month is too early for most infants as their visual system is still developing. Similarly, 6 to 8 months and 12 months are beyond the normal age range for achieving binocularity, and delayed achievement could indicate potential issues like strabismus, which may lead to visual impairment if not addressed.

2. A 10-month-old infant is diagnosed with gastroesophageal reflux. An esophageal (pH) probe monitor is ordered. What explanation for the purpose of the esophageal probe should the nurse provide to the parents?

• A. Assist in the passage of formula through the esophagus
• B. Identify the number of reflux episodes that are occurring
• C. Determine the time it takes for the stomach to empty its contents
• D. Monitor the pH within the stomach

Correct answer: B

Rationale: The correct answer is B. The esophageal pH probe is used to identify the frequency and severity of reflux episodes by measuring the pH in the esophagus. Choice A is incorrect because the probe does not assist in the passage of formula through the esophagus. Choice C is incorrect as determining the time it takes for the stomach to empty its contents would require a different procedure. Choice D is incorrect as the esophageal pH probe monitors the pH in the esophagus, not the stomach.

3. Why is it difficult to assess a child’s dietary intake?

• A. No systematic assessment tool has been developed
• B. Biochemical analysis for assessing nutrition is expensive
• C. Families usually do not understand much about nutrition
• D. Recall of food consumption is frequently unreliable

Correct answer: D

Rationale: The correct answer is D. Recall of food intake, especially amounts eaten, is often unreliable. While systematic tools like the 24-hour recall and dietary history questionnaires exist, recall can still be challenging in accurately assessing a child's dietary intake. Choices A, B, and C are incorrect because systematic assessment tools do exist, biochemical analysis is not the primary method for dietary assessment, and families' understanding of nutrition may vary but is not the main reason for the difficulty in assessing a child's dietary intake.

4. What is one focus of current health care?

• A. Increased provision of nursing services
• B. Disease prevention
• C. Symptom management
• D. Identification of disease processes

Correct answer: B

Rationale: The correct answer is 'Disease prevention.' Modern healthcare places emphasis on preventing diseases to enhance overall health and well-being. While nursing services, symptom management, and disease identification are crucial components of healthcare, disease prevention plays a key role in reducing the burden of illness on individuals and communities.

5. What diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?

• A. Renal ultrasonography
• B. Computed tomography
• C. Intravenous pyelography
• D. Voiding cystourethrography

Correct answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.
