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.

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: C

Rationale: After delivery, bradycardia (pulse rate 50-70 beats/min) may occur, reflecting the large amount of blood returning to the central circulation after delivery of the placenta. The increase in central circulation results in increased stroke volume, allowing a slower heart rate to provide adequate maternal circulation. A pulse rate of 55 beats/min falls within the normal range post-delivery, so there is no need to notify the healthcare provider immediately. It is important for the client to remain on bed rest in the immediate postpartum period to prevent complications. While range-of-motion exercises are beneficial for a client on bed rest, it is not the priority based on the data provided. Therefore, the most appropriate nursing action is to document the finding for accurate record-keeping and monitoring of the client's condition.

Correct Answer: D

Rationale: The correct answer is hepatitis A. DTaP, MMR, and Hib are all part of the regular schedule of immunizations for children to protect them against diseases like diphtheria, tetanus, pertussis, measles, mumps, rubella, and Haemophilus influenzae type b. Hepatitis A vaccine is not included in the routine childhood immunization schedule but may be recommended in certain situations or regions where the disease is more prevalent. Hepatitis A is generally considered an optional vaccine for children but can be administered based on specific risk factors or regional guidelines.

Correct Answer: A

Rationale: To improve overall health, the nurse should prioritize assisting the client in making lifestyle changes that have the most significant impact on health. Drinking a six-pack of beer each day can have serious negative effects on health, including liver damage, increased risk of chronic diseases, and addiction. By addressing this habit first, the nurse can make a substantial positive difference in the client's health. Eating an occasional chocolate bar, exercising twice a week, and using relaxation exercises to deal with stress are beneficial habits, but they are not as detrimental to health as excessive alcohol consumption. Therefore, they are not the highest priority for immediate lifestyle changes to improve health.
