At about what age does the Babinski sign disappear?

Correct Answer: D

Rationale: The Babinski sign is a reflex response in infants where their big toe moves upward and the other toes fan out when the sole of the foot is stroked. This reflex is normally present in infants up to around 2 years of age. By the age of 2, the nervous system has matured, and the Babinski sign disappears as the child's motor pathways develop and the reflex becomes suppressed. After the age of 2, the presence of the Babinski sign can indicate neurological issues, so its absence beyond this age is considered normal.

Correct Answer: C

Rationale: Unintentional injuries are the major cause of death for children older than 1 year. These include accidents such as drownings, car accidents, fires, falls, and poisoning. Children are curious and naturally explore their environment, which can put them at risk for accidents. It is important for parents and caregivers to create safe environments for children, supervise them closely, and take appropriate safety precautions to prevent these injuries. By being mindful of potential hazards and actively working to prevent accidents, we can help reduce the incidence of unintentional injuries and protect children's well-being.

Correct Answer: B

Rationale: House rules are negotiated: In maintaining therapeutic nurse-family boundaries, it is important for the nurse to establish clear and appropriate boundaries by involving the family in negotiating house rules. This helps to define roles and responsibilities, promoting mutual respect and understanding between the nurse and the family. By negotiating house rules, the nurse can create a structured environment that supports the well-being of the family.

Correct Answer: B

Rationale: The appropriate procedure for obtaining a child's blood pressure is to ask the child to come to the exam room to obtain the blood pressure. This is important because the exam room provides a quiet and controlled environment, which is conducive to accurately measuring blood pressure. Taking the blood pressure in the playroom may lead to inaccurate readings due to distractions and noise. Similarly, asking the child to return to his or her room for the blood pressure and then escorting the child back to the playroom is not necessary and may disrupt the child's play. Documenting that the blood pressure was not obtained because the child was in the playroom is not a valid or appropriate action as it is important to ensure the child's health and monitor their blood pressure in a suitable environment. Therefore, the best course of action is to ask the child to come to the exam room to obtain the blood pressure.

Correct Answer: C

Rationale: The correct statement regarding chlamydia infection is that the clinical manifestations include dysuria and urethral itching in males. Chlamydia is a sexually transmitted infection caused by the bacterium Chlamydia trachomatis. In males, common symptoms include a burning sensation during urination (dysuria) and urethral itching. It is important to note that chlamydia is often asymptomatic, especially in women, which is why regular screening is important to detect and treat the infection early. Option A is incorrect because the treatment of choice for chlamydia is typically antibiotics such as azithromycin or doxycycline, not oral penicillin. Option B is incorrect because nystatin or miconazole are used to treat fungal infections, not chlamydia. Option D is incorrect because small, painful vesicles on genital areas are more indicative of herpes simplex virus infection rather than chlamydia
