Correct Answer: B

Rationale: Erik Erikson is credited with the psychosocial development theory and eight stages. The nurse should consider these stages when caring for pediatric clients to evaluate their development. Jean Piaget is known for cognitive development, Sigmund Freud for psychosexual development, and Robert Peck for aging theory. Therefore, the correct answer is Erik Erikson.

Correct Answer: B

Rationale: Single mothers with two or three children are indeed the fastest-growing segment of the homeless population. These families, where the majority of children are under the age of five, make up more than one-third of the homeless population in the United States. While single, adult men have traditionally been the largest group in the homeless population, single mothers with children have been increasing in numbers. Runaway adolescents, although a significant group of homeless children, do not represent the fastest-growing segment of the homeless population. Single, adult women are not specified as the fastest-growing segment.

Correct Answer: C

Rationale: To determine the correct infusion rate, divide the total volume of fluids (1,000 mL) by the total infusion time (8 hours), resulting in a rate of 125 mL/hr. This calculation ensures the appropriate administration of fluids over the specified time period. Choice A (100 mL/hr) is incorrect as it does not match the calculated rate based on the given information. Choice B (125 mL/min) is inaccurate because the question specifies the rate in hours, not minutes. Choice D (80 mL/min) is incorrect as it provides the rate in minutes rather than hours, which is the required unit for this scenario.

Correct Answer: D

Rationale: An extended care facility typically provides long-term care for individuals who require continuous assistance with activities of daily living. A nursing facility fits this description as it offers skilled nursing care and assistance with daily activities. Choices A, B, and C are incorrect because a home health agency provides care in the patient's home, a suicide prevention center focuses on mental health crisis intervention, and a state-owned psychiatric hospital offers mental health treatment, none of which are synonymous with extended care facilities.

Correct Answer: C

Rationale: In the Phalen test, the nurse asks the client to hold the hands back to back while flexing the wrists 90 degrees. This position puts pressure on the median nerve, eliciting symptoms in carpal tunnel syndrome. Dorsiflexing or plantarflexing the foot and hyperextending the fingers are not associated with testing for carpal tunnel syndrome. Acute flexion of the wrist for 60 seconds produces no symptoms in the normal hand.
