1. A preschooler has successfully completed the test item 'counts 5 blocks' on the Denver II test. This pass is evidence of which of the following developmental concepts?

• A. centration
• B. causality
• C. nonreversibility
• D. conservation

Correct answer: D

Rationale: The ability of a preschooler to move five blocks to a piece of paper and state there are five blocks on the paper is evidence that the preschooler has the ability of conservation. This concept refers to the fact that the quantity of something doesn't change just because the shape, contour, and so on has changed. Five blocks are still five blocks, whether they are lying beside the paper, stacked on the paper, or moved to the paper. Centration is the ability to concentrate on one feature of a situation while neglecting all other aspects. Causality is based on the sequence of events, one event ordinarily following another. Non-reversibility refers to the inability of preschoolers to reverse their operations. They are only able to think forward, not retrace or reverse their thought processes.

2. The client has an order for an IV piggyback of Ceftriaxone 750mg in 50mL D5W to run over 30 minutes. What is the appropriate drip rate?

• A. 100 mL/hr
• B. 150 mL/hr
• C. 200 mL/hr
• D. 50 mL/hr

Correct answer: A

Rationale: To calculate the drip rate, you need to convert the time from minutes to hours. The formula is (Volume to be infused / Time for infusion in minutes) x (60 minutes / 1 hour). Substituting the values, (50 mL / 30 min) x (60 min / 1 hr) = 100 mL/hr. Therefore, the appropriate drip rate is 100 mL/hr. Choices B, C, and D are incorrect as they do not match the calculated drip rate. Option A, 100 mL/hr, is the correct drip rate for administering Ceftriaxone 750mg in 50mL D5W over 30 minutes.

3. 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.

4. A nurse is palpating a client's sinus areas. Which sensation does the nurse expect the client to indicate that he or she is feeling during palpation if the sinuses are normal?

• A. Firm pressure
• B. Pain behind the eyes
• C. Pain during palpation
• D. Pressure producing an acute headache

Correct answer: A

Rationale: The correct answer is A: Firm pressure. When the sinuses are normal, the client is expected to feel firm pressure during palpation. Pain during palpation of the sinuses is indicative of acute sinusitis, not a normal finding. Pain behind the eyes and pressure producing an acute headache are symptoms of acute sinusitis, not sensations felt during sinus palpation in normal sinuses.

5. An adult client tells the clinic nurse that he is susceptible to middle ear infections. About which risk factor related to infection of the ears does the nurse question this client?

• A. Loud music
• B. Use of power tools
• C. Occupational noise
• D. Exposure to cigarette smoke

Correct answer: D

Rationale: The correct answer is 'Exposure to cigarette smoke.' Otitis media (middle ear infection) is associated with various factors like colds, allergies, sore throats, and blockage of the eustachian tubes. Risk factors include exposure to cigarette smoke, youth (as otitis media is usually a childhood disease), congenital abnormalities, immune deficiencies, family history of otitis media, recent upper respiratory infections, and allergies. Choices A, B, and C (Loud music, Use of power tools, and Occupational noise) are more likely to cause hearing loss rather than being direct risk factors for middle ear infections.
