Parents of a newborn are concerned because the infant's eyes often "look crossed" when the infant is looking at an object. The nurse's response is that this is normal based on the knowledge that binocularity is normally present by what age?

Correct Answer: C

Rationale: Binocularity refers to the ability of both eyes to focus on the same object and create a single, three-dimensional image. In infants, binocularity typically develops between the ages of 6 to 8 months. Prior to this age, it is common for infants to show occasional misalignment or "crossed" eyes when focusing on an object. This is usually a normal part of the visual development process and tends to resolve as binocular vision strengthens with age. Therefore, it is considered normal for newborns to show occasional crossed eyes until binocularity develops around 6 to 8 months of age.

Correct Answer: A

Rationale: Young people with anorexia nervosa are often described as independent. This is because individuals with anorexia nervosa tend to exhibit strong willpower and control over their behavior, often making independent decisions related to their eating habits and body image. They may resist help or intervention, preferring to maintain control over their food intake and weight loss. This independence can make it challenging to address and treat anorexia nervosa effectively, as individuals may be resistant to seeking or accepting help.

Correct Answer: A

Rationale: Bacterial meningitis is considered the most significant form of meningitis because it is a serious, life-threatening condition that requires immediate medical attention. Bacterial meningitis is caused by bacteria infecting the protective membranes covering the brain and spinal cord. It can lead to complications such as brain damage, hearing loss, and even death if not treated promptly with antibiotics. Bacterial meningitis is more severe than viral or aseptic meningitis, hence why it is considered the most significant form.

Correct Answer: A

Rationale: When administering a narcotic analgesic like Morphine, assessing the client's level of alertness and respiratory rate is crucial to monitor for any adverse effects such as respiratory depression. Morphine can cause respiratory depression as one of its side effects, especially in higher doses. By assessing the client's respiratory rate and level of alertness before administering the medication, the nurse can ensure the client's safety and take appropriate action if any signs of respiratory depression occur. This assessment is essential in preventing potential complications and ensuring the client's well-being during pain management.

Correct Answer: B

Rationale: A latex condom with spermicide provides the best protection against HIV transmission during sexual intercourse. Safer sex practices for persons with HIV involve using condoms consistently and correctly during every sexual encounter to reduce the risk of HIV transmission to partners, regardless of their HIV status. Spermicide, while offering additional protection against pregnancies, does not provide additional protection against HIV transmission. Other contraceptive methods like birth control pills, implants, and injections are not effective in preventing HIV transmission. The intrauterine device is also not specifically recommended for clients with HIV as it does not provide protection against HIV transmission during sexual activities.
