1. When performing an eye examination, which area can a healthcare provider best visualize using an ophthalmoscope?

• A. Iris
• B. Cornea
• C. Optic disc
• D. Conjunctiva

Correct answer: C

Rationale: An ophthalmoscope is a tool used to visualize the internal structures of the eye during an examination. The optic disc, located on the internal surface of the retina, can be best visualized using an ophthalmoscope. The iris, cornea, and conjunctiva are superficial structures that can be examined without the need for an ophthalmoscope. Therefore, the correct answer is the optic disc. Choices A, B, and D are incorrect because they are external structures that can be examined directly without the use of an ophthalmoscope.

2. A healthcare professional reviewing a client's record notes documentation that the client has melena. How does the healthcare professional detect the presence of melena?

• A. By checking the client's urine for blood
• B. By checking the client's stool for blood
• C. By checking the client's urine for a decrease in output
• D. By checking the client's bowel movements for diarrhea

Correct answer: B

Rationale: Melena' is the term used to describe abnormal black tarry stool that has a distinctive odor and contains digested blood. It usually results from bleeding in the upper gastrointestinal tract and is often a sign of peptic ulcer disease or small bowel disease. The presence of melena is detected by checking the client's stool for blood. Blood in the client's urine, decreased urine output, and diarrhea are not associated with the assessment for melena.

3. A 2-year-old child diagnosed with HIV comes to a clinic for immunizations. Which of the following vaccines should the healthcare provider expect to administer in addition to the scheduled vaccines?

• A. pneumococcal vaccine
• B. hepatitis A vaccine
• C. Lyme disease vaccine
• D. typhoid vaccine

Correct answer: A

Rationale: The correct answer is the pneumococcal vaccine. Children with HIV are at increased risk of pneumococcal infections, so the pneumococcal vaccine is recommended as a supplemental vaccine for them. The hepatitis A vaccine is not routinely given to HIV-positive children unless they have other risk factors for hepatitis A. Lyme disease vaccine is for individuals at risk for Lyme disease, not routinely recommended for a 2-year-old. Typhoid vaccine is typically given to individuals traveling to endemic areas or working in settings with potential exposure to Salmonella typhi, not a routine vaccine for a 2-year-old with HIV.

4. A nurse in the healthcare provider's office is checking the Babinski reflex in a 3-month-old infant. The nurse determines that the infant's response is normal if which finding is noted?

• A. The fingers curl tightly, and the toes curl forward.
• B. The toes flare, and the big toe is dorsiflexed.
• C. There is extension of the extremities on the side to which the head is turned, with flexion on the opposite side.
• D. The infant turns to the side that is touched.

Correct answer: B

Rationale: To elicit the Babinski reflex, the nurse strokes the lateral sole of the foot from the heel to across the base of the toes. In the expected response, the toes flare, and the big toe dorsiflexes. The Babinski reflex disappears at 12 months of age. Turning to the side that is touched is the expected response when the rooting reflex is elicited. Tight curling of the fingers and forward curling of the toes is the expected response when the grasp reflex (palmar and plantar) is elicited. Extension of the extremities on the side to which the head is turned with flexion on the opposite side is the expected response when the tonic neck reflex is elicited.

5. In conducting a health screening for 12-month-old children, the nurse expects them to have been immunized against which of the following diseases?

• A. measles, polio, pertussis, hepatitis B
• B. diphtheria, pertussis, polio, tetanus
• C. rubella, polio, pertussis, hepatitis A
• D. measles, mumps, rubella, polio

Correct answer: B

Rationale: By 12 months of age, children should have received the DTaP (diphtheria, pertussis, and tetanus) vaccine along with the polio vaccine. The MMR (measles, mumps, and rubella) vaccine is not typically given until the child is 12-15 months old. Therefore, option B is correct as it includes vaccines that are usually administered by 12 months of age. Options A, C, and D are incorrect as they include vaccines that are typically given after 12 months of age.
