A nurse is teaching a class about Piaget's stages of cognitive development.
The nurse should instruct that object permanence develops during which of the following stages?

Choice A rationale:

The CDC and other health organizations recommend at least 150 minutes of moderate-intensity aerobic exercise per week for overall health, which includes benefits for bone health. Weight-bearing exercises are particularly important for preventing osteoporosis.

Choice B rationale:

Performing vigorous exercise at least 2 times per week is generally recommended for maintaining cardiovascular health and overall fitness. However, for a client at risk for osteoporosis, the primary focus should be on calcium and vitamin D intake to support bone health and density. Vigorous exercise alone may not provide the necessary nutrients for bone health.

Choice C rationale:

Taking 400 IU of vitamin D supplement each day is a reasonable recommendation to support bone health, as vitamin D is essential for calcium absorption. However, the primary concern for a client at risk for osteoporosis is calcium intake. While vitamin D is important, calcium supplementation is more critical for addressing this specific issue.

Choice D rationale:

The RDA for calcium is generally 1,000 mg for adults up to age 50 and 1,200 mg for women over 50 and men over 70. For someone at risk of osteoporosis, ensuring adequate calcium intake is essential for bone health.

Choice A rationale;

Inability to form healthy relationships: This is more commonly associated with fixation at the phallic stage.

Choice B rationale:

Feelings of shame are associated with Freud's psychosexual stages, particularly during the anal stage. Fixation at the oral stage is more likely to result in issues related to dependency and oral fixation, which may manifest as habits like nail-biting or smoking, rather than feelings of shame.

Choice C rationale:

According to Freud's psychosexual theory, fixation at the oral stage can lead to oral personality traits. These traits are often associated with oral activities like eating, drinking, smoking, and talking. Overeating is a common behavior linked to oral fixation, as it represents a seeking of oral gratification.

Choice D rationale:

Bedwetting is not typically associated with fixation at the oral stage of development. Bedwetting is more commonly linked to issues at the anal stage. In the oral stage, the fixation is primarily related to dependency and oral behaviors. .
