What hormone is important in milk production and maintaining lactation?
- A. Estrogen
- B. Oxytocin
- C. Prolactin
- D. Adrenaline
Correct Answer: C
Rationale: Prolactin is the correct answer because it is the hormone produced by the pituitary gland that stimulates milk production in the mammary glands. During lactation, prolactin levels remain elevated to ensure a continuous supply of milk. While oxytocin is involved in milk ejection, prolactin is primarily responsible for milk synthesis and maintenance of lactation.

A nurse counseling a patient diagnosed with dissociative identity disorder (DID) should understand that the assessment of highest priority is:
- A. risk for self-harm
- B. cognitive functioning
- C. identification of drug abuse
- D. readiness to reestablish identity or memory
Correct Answer: A
Rationale: The correct answer is A: risk for self-harm. In patients with DID, the primary concern is ensuring their safety due to the high risk of self-harm or suicide. Assessing this risk is crucial for immediate intervention to prevent harm. Choice B, cognitive functioning, may be important but is secondary to ensuring patient safety. Choice C, identification of drug abuse, is relevant but not as urgent as addressing the risk for self-harm. Choice D, readiness to reestablish identity or memory, is important but not as critical as ensuring the patient's safety. Therefore, assessing the risk for self-harm takes precedence in the care of a patient with DID.
