Fat emulsions are frequently administered as a part of total parenteral nutrition. Which statement is true regarding fat emulsions?
- A. They have a high energy-to-fluid-volume ratio.
- B. Even though hypertonic, they are well tolerated.
- C. They are a basic solution due to the addition of sodium hydroxide (NaOH).
- D. The pH is alkaline, making them compatible with most medications.
Correct Answer: A
Rationale: The correct statement is that fat emulsions have a high energy-to-fluid-volume ratio. Fat emulsions are formulated in 10%, 20%, and 30% solutions and supply 1.1, 2, and 3 kilocalories, respectively, for each milliliter. In comparison, a milliliter of 5% dextrose only supplies 0.17 kilocalories. Choices B, C, and D are incorrect. Choice B is false because fat emulsions are essentially pH neutral and isotonic, not hypertonic. Choice C is incorrect because fat emulsions are not basic solutions; they are essentially pH neutral. Choice D is incorrect as fat emulsions are not alkaline; they are pH neutral, making them compatible with most medications.

What are the three major sequential maturational crises for females?
- A. puberty, pregnancy, and menopause.
- B. death of a spouse, menopause, and childbirth.
- C. rape, divorce, and menarche.
- D. dating, engagement, and separation.
Correct Answer: A
Rationale: The three major sequential maturational crises affecting females are puberty, pregnancy, and menopause. Puberty signifies the beginning of menarche, the first menstrual period. Pregnancy is a transformative experience with long-lasting effects on a woman's life. Menopause marks the end of menstrual cycles. These milestones are well-documented in research and are significant events in a woman's life. Nurses play a vital role in supporting females through these stages. Choices B, C, and D are incorrect as they do not accurately represent the recognized sequential maturational crises in a female's life.
A primary belief of psychiatric mental health nursing is:
- A. Most people have the potential to change and grow.
- B. Every person is worthy of dignity and respect.
- C. Human needs are individual to each person.
- D. Some behaviors have no meaning and cannot be understood.
Correct Answer: B
Rationale: The correct answer is that every person is worthy of dignity and respect. This is a fundamental principle in psychiatric mental health nursing, emphasizing the importance of treating individuals with dignity and respect regardless of their condition. This belief forms the basis of establishing a therapeutic nurse-client relationship. Choice A is a positive belief, but the primary focus in psychiatric mental health nursing is on respecting the worth and dignity of each individual. Choice C is related to understanding individual human needs but does not encompass the core value of dignity and respect. Choice D is incorrect as psychiatric nursing emphasizes the importance of interpreting and understanding all behaviors as meaningful expressions of the client's experience.
The nurse is assessing an elder whom the nurse suspects is being physically abused. The most important question for the nurse to ask is:
- A. "How much money do you keep around the house?"?
- B. "Who provides your physical care?"?
- C. "How close does your nearest relative live?"?
- D. "What form of transportation do you use?"?
Correct Answer: B
Rationale: The most important question for the nurse to ask when suspecting elder abuse is 'Who provides your physical care?' This question is crucial as the primary caregiver, who is often the abuser in cases of elder abuse, lives with the client. Research has shown that spouses and adult children are the most common abusers. By inquiring about the provider of physical care, the nurse can assess the potential abuser's proximity to the elder. Choices A, C, and D are less pertinent to identifying the primary caregiver, who is more likely to be the abuser.
A health care worker is concerned about a new mother being overwhelmed by caring for her infant. What should the health care worker do?
- A. Immediately contact child protective services.
- B. Provide the mother with literature about child care.
- C. Consult a therapist to help the mother work out her fears.
- D. Refer the mother to parenting classes.
Correct Answer: D
Rationale: When a health care worker is concerned about a new mother being overwhelmed by caring for her infant, the best course of action is to refer the mother to parenting classes. Prevention of child abuse is focused on educating parents on how to care for their child and handle the demands of infant care. By attending parenting classes, the mother can build self-confidence, self-esteem, and coping skills. Parenting classes help parents understand the developmental needs of their children and learn effective ways to manage their home environment. Additionally, these classes provide parents with increased social contacts and knowledge about community resources. Contacting child protective services (choice A) should not be the immediate action as there is no indication of abuse. Providing literature about child care (choice B) may not be as effective as hands-on parenting classes. Consulting a therapist (choice C) may be beneficial, but addressing parenting skills through classes is more appropriate in this scenario.
Social support systems include all of the following except:
- A. call-in help lines
- B. emotional assistance provided by others
- C. community support groups
- D. use of coping skills and verbalization for anger management
Correct Answer: D
Rationale: The correct answer is the use of coping skills and verbalization for anger management. Social support systems involve external sources of support from others or the community. Call-in help lines, emotional assistance provided by others, and community support groups all represent social support systems where individuals can seek help and assistance from outside sources. On the other hand, the use of coping skills and verbalization for anger management refers to individual strategies rather than external social support.
