1. What is the transparent membrane that focuses the light entering the eyes onto the retina?

• A. Lens
• B. Sclera
• C. Cornea
• D. Pupils

Correct answer: A

Rationale: The correct answer is the lens. The lens is a transparent structure in the eye that helps to focus light onto the retina, which is essential for clear vision. The cornea and sclera are also important parts of the eye, but the lens specifically plays a crucial role in focusing light onto the retina. The sclera is the white outer layer of the eye that helps maintain the shape of the eye, while the cornea is the clear outer covering of the eye that helps to refract light into the eye.

2. How many milliliters are equal to 20 cc?

• A. 2
• B. 20
• C. 2000
• D. 20000

Correct answer: B

Rationale: 1 cc (cubic centimeter) is equal to 1 ml. Therefore, 20 cc is equal to 20 ml. To convert between cubic centimeters (cc) and milliliters (ml), the values are equivalent since they both measure volume in the metric system. Choice A (2) is incorrect as it does not account for the direct conversion between cc and ml. Choice C (2000) and choice D (20000) are incorrect as they represent conversions based on a misunderstanding of the relationship between cc and ml.

3. A caregiver is caring for a 5-month-old infant who has manifestations of severe dehydration and a prescription for parenteral fluid therapy. The caregiver asks, 'What are the indications that my baby needs an IV?' Which of the following responses should the caregiver make?

• A. Your baby needs an IV because she is not producing any tears
• B. Your baby needs an IV because her fontanels are bulging
• C. Your baby needs an IV because she is breathing slower than normal
• D. Your baby needs an IV because her heart rate is decreasing

Correct answer: A

Rationale: The correct response is A: 'Your baby needs an IV because she is not producing any tears.' In infants, the inability to produce tears is a sign of severe dehydration. This is a crucial indication for the need for intravenous (IV) fluid therapy to rehydrate the infant. While the other options may also be symptoms of dehydration, the absence of tears is a more direct and specific indicator requiring immediate attention and intervention.

4. What is the most common cause of dementia among elderly persons?

• A. Parkinson’s disease
• B. Multiple sclerosis
• C. Amyotrophic lateral sclerosis (Lou Gehrig’s disease)
• D. Alzheimer’s disease

Correct answer: D

Rationale: Alzheimer’s disease is the most common cause of dementia among elderly persons. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. While Parkinson’s disease, multiple sclerosis, and amyotrophic lateral sclerosis are serious conditions, they are not typically associated with dementia in the same way Alzheimer’s disease is. Therefore, the correct answer is D.

5. What is the correct sequence for assessing the abdomen?

• A. Tympanic percussion, measurement of abdominal girth, and inspection
• B. Assessment for distention, tenderness, and discoloration around the umbilicus
• C. Percussion, palpation, and auscultation
• D. Auscultation, percussion, and palpation

Correct answer: D

Rationale: The correct sequence for assessing the abdomen is auscultation, percussion, and palpation. Auscultation allows the healthcare provider to listen for bowel sounds, followed by percussion to assess for areas of tenderness or abnormal distention, and finally palpation to feel for masses or organ enlargement. This sequence ensures a systematic and thorough assessment of the abdomen.
