1. What is the BEST blood collection location for a newborn?
- A. the AC
- B. the veins of the forehead
- C. the heel
- D. the fingertips
Correct answer: C
Rationale: When collecting blood from newborns, it is safest and most commonly done by collecting blood from the lateral or medial aspect of the baby's heel. This location is preferred due to the accessibility of the veins and the minimal discomfort caused to the newborn. Veins in the forehead are not commonly used for blood collection in newborns. The fingertips are not optimal for blood collection in newborns due to their small size and the potential for causing discomfort. The AC (antecubital) area, typically used in adults for blood collection, is not recommended for newborns due to the size of their veins and the potential risk of injury.
2. For a healthcare worker under normal conditions with unsoiled hands, effective hand hygiene between patients requires which of the following?
- A. At least a 15-second scrub with plain soap and water
- B. At least a 23-minute scrub with an antimicrobial soap
- C. Use of an alcohol-based antiseptic hand-rub
- D. Wearing a mask when scrubbing
Correct answer: C
Rationale: Effective hand hygiene between patients for a healthcare worker with unsoiled hands involves using an alcohol-based antiseptic hand rub. This method is sufficient for cleaning hands that are not visibly soiled. The use of an antimicrobial soap or a prolonged scrubbing time is unnecessary and not recommended in this scenario. Wearing a mask is not required for routine hand hygiene and does not contribute to effective hand cleaning.
3. A woman who has lived in the United States for a year after moving from Europe has learned to speak English and is almost finished with her college studies. She now dresses like her peers and says that her family in Europe would hardly recognize her. This situation illustrates which concept?
- A. Integration
- B. Assimilation
- C. Biculturalism
- D. Heritage consistency
Correct answer: B
Rationale: Assimilation is a unidirectional, linear process moving from unacculturated to acculturated, in which a person develops a new cultural identity and becomes like members of the dominant culture. In this scenario, the woman has adapted to the new culture by learning the language, dressing like her peers, and expressing that her family in Europe would hardly recognize her. This aligns with the process of assimilation. Integration and biculturalism, on the other hand, involve bidirectional and bidimensional processes that induce reciprocal change in both cultures while maintaining aspects of the original culture in one's ethnic identity. Since there is no indication in the question that the woman has retained aspects of her original culture, integration and biculturalism are not the correct concepts. Heritage consistency refers to the degree to which one retains their original or traditional culture, which is not addressed in the scenario provided.
4. A 2-year-old child has been brought to the clinic for a well-child checkup. What is the best way for the nurse to begin the assessment?
- A. Ask the parent to place the child on the examining table.
- B. Have the parent remove all of the child's clothing before the examination.
- C. Allow the child to keep a security object such as a toy or blanket during the examination.
- D. Initially focus the interactions on the child, essentially ignoring the parent until the child's trust has been obtained.
Correct answer: C
Rationale: The best place to examine the toddler is on the parent's lap. Toddlers understand symbols; therefore, a security object is helpful. Initially, the focus is more on the parent, which allows the child to adjust gradually and to become familiar with you. A 2-year-old child does not like to take off his or her clothes. Therefore, ask the parent to undress one body part at a time.
5. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?
- A. Pituitary
- B. Pineal
- C. Pancreas
- D. Hypothalamus
Correct answer: B
Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.
