1. Which of the following is a factor that affects Basal Metabolic Rate (BMR)?
- A. Age
- B. Sleep
- C. Fasting/Starvation
- D. Activity Level
Correct answer: All of the above
Rationale: All the listed options (Age, Sleep, Fasting/Starvation, Activity Level) are factors that can affect a person's Basal Metabolic Rate (BMR). BMR is the number of calories your body needs to accomplish its most basic (basal) life-sustaining functions. Age can affect BMR as metabolism slows with age. Sleep can influence BMR as metabolism slows during sleep. Fasting or starvation can decrease BMR as the body conserves energy. Activity level can also influence BMR; the more active you are, the higher your BMR, as your body requires more energy for physical activities.
2. In females, the twenty-third pair of chromosomes is labeled as __________.
- A. an autosome
- B. dizygotic
- C. XX
- D. XY
Correct answer: C
Rationale: In females, the twenty-third pair of chromosomes is indeed labeled as XX. This pair of chromosomes determines the biological sex of females. Choice A, 'an autosome,' is incorrect as autosomes refer to the non-sex chromosomes. Choice B, 'dizygotic,' is incorrect as it relates to twins. Choice D, 'XY,' is incorrect as it represents the chromosome pair found in males.
3. Integrated health care systems function in a variety of models. Which of the following is a common characteristic of all systems?
- A. Deliver selective care only
- B. Deliver a whole continuum of care
- C. Treat patients only in the hospital
- D. Provide care only in the primary care setting
Correct answer: B
Rationale: Integrated health care systems are designed to provide a whole continuum of care, which includes preventive, primary, specialty, hospital, and long-term care services. This integration ensures that patients receive comprehensive and coordinated care across different healthcare settings. Choice A is incorrect because integrated systems aim to provide a wide range of services, not selective care only. Choice C is incorrect as integrated systems extend care beyond hospital settings. Choice D is incorrect as these systems offer care across various settings, not limited to primary care only.
4. Earliest sign of skin reaction to radiation therapy is:
- A. desquamation
- B. erythema
- C. atrophy
- D. pigmentation
Correct answer: D
Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.
5. Children from lower-SES families ________.
- A. are more likely to be resilient adults than those from higher-SES families.
- B. show no signs of ill effects if there is an increase in SES before age 5.
- C. are not affected by SES status unless persistent employment is the reason for the economic hardships of the family.
- D. are less likely to show ill effects of SES status if they possess a high IQ and develop healthy attachments to adults and peers.
Correct answer: D
Rationale: Children from lower-SES families are less likely to show ill effects of SES status if they possess a high IQ and develop healthy attachments. Choice A is incorrect because children from lower-SES families typically face more challenges and are not inherently more resilient. Choice B is incorrect as an increase in SES may not erase the effects of early socioeconomic disadvantages. Choice C is incorrect as SES status can impact children from lower-SES families regardless of the reason for economic hardships.
