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.

Correct Answer: C

Rationale: The correct answer is 'Frequent urination and burning when I urinate are expected.' This statement by the mother indicates a need for further information because these symptoms are not normal and could indicate a urinary tract infection or another issue that needs medical attention. The other choices correctly reflect signs and symptoms that should be reported to the health care provider. Redness, swelling, or tenderness in the legs can indicate a blood clot, and feelings of pelvic fullness or pressure can be signs of a problem. Monitoring temperature is also important to ensure there is no infection or other complications postpartum.

Correct Answer: D

Rationale: The correct answer is D: Peripheral vision. The confrontation test is a gross measure of peripheral vision. It compares the client's peripheral vision with the nurse's, assuming that the nurse's vision is normal. During the test, the nurse positions themselves at eye level with the client, about 2 feet away, and directs the client to cover one eye with an opaque card. The nurse covers the eye opposite the client's covered one and slowly moves a target (like a pencil) from the periphery in several directions. The client is asked to indicate when they see the target, which should coincide with when the nurse sees it. Near vision is tested using a handheld vision screener with various sizes of print, color vision with the Ishihara test, and distant vision with a Snellen chart. Therefore, choices A, B, and C are incorrect as they do not measure peripheral vision, which is the focus of the confrontation test.

Correct Answer: A

Rationale: When a client seeks information about birth control, it is essential for the nurse to first assess the client's existing knowledge on the subject. This enables the nurse to provide tailored information that complements what the client already knows, facilitating better understanding and decision-making. Providing written material is a helpful educational tool but should not be the first intervention. Offering specific advice on birth control methods based on age and lifestyle limits the client's autonomy and decision-making process. Mentioning the client's boyfriend as a requirement for discussing birth control is inappropriate and nontherapeutic, as the client should be able to seek information independently.

Correct Answer: D

Rationale: The correct answer is DTaP. DTaP is administered at 2, 4, and 6 months of age; between 15 and 18 months of age; and between 4 and 6 years of age. Since the child has only received three doses of this vaccine, the next dose of DTaP should be administered. The other options are incorrect because Hib is administered at 2, 4, and 6 months of age and between 12 and 15 months; IPV is administered at 2, 4, and 6 months of age and between 4 and 6 years of age; MMR is administered between 12 and 15 months of age and again between 4 and 6 years of age.
