While performing a physical assessment on a 6-month-old infant, the nurse observes head lag. Which of the following nursing actions should the nurse perform first?

Correct Answer: B

Rationale: Head lag should be completely resolved by 4 months of age. Continuing head lag at 6 months of age indicates the need for further developmental or neurological evaluation. Laying the infant on his stomach promotes muscle development of the neck and shoulder muscles, but because of the age of this child, a referral should be the first action. The findings are abnormal for a 6-month-old infant. Significant head lag can be seen in infants with Down syndrome and hypoxia, as well as neurological and other metabolic disorders. While some of these disorders might include developmental delays, stating this to the parents without a proper evaluation can cause unnecessary distress. The priority is to identify the cause of the head lag through a medical evaluation before discussing potential outcomes with the parents.

Correct Answer: B

Rationale: Some studies have shown that ginseng enhances in vitro sperm motility, making Choice B the correct response. It directly addresses the client's comments about taking ginseng and provides valuable information regarding its potential effect on sperm motility. Alternative therapies are often sought by couples struggling with infertility, and acknowledging the potential benefits of ginseng can empower the client. Choice A is incorrect as it slightly misrepresents the evidence by overgeneralizing its effectiveness. Choice C dismisses ginseng without acknowledging its potential benefits, potentially closing off a fruitful discussion with the client. Choice D, while neutral, misses the opportunity to validate the client's choice and explore further options collaboratively. It is crucial for nurses to respect clients' choices, provide accurate information, and guide them effectively in exploring different alternatives.

Correct Answer: A

Rationale: Sex role identification begins during infancy as infants can identify body parts by the end of the first year. Preschoolers often engage in masturbation and sex play. School-age children continue to develop awareness of their sexual identity, including behaviors like hugging and kissing. Early adolescence sees further development influenced by sexual maturation and experimentation with sex roles. Therefore, the correct statement is that sex role identification begins in infancy. Choices B, C, and D are incorrect as they misrepresent the timeline of the development of sex role identification in children.

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.
