1. When planning a cultural assessment, which component should be included?
- A. Family history
- B. Chief complaint
- C. Medical history
- D. Health-related beliefs
Correct answer: D
Rationale: When planning a cultural assessment, the nurse should include the component of health-related beliefs. Understanding a person's cultural background and beliefs about health and wellness is crucial for providing culturally competent care. Health-related beliefs can impact a person's attitudes towards illness, treatment preferences, and adherence to medical recommendations. Therefore, assessing health-related beliefs is essential for delivering effective and respectful healthcare services. Choices A, B, and C are important components of a comprehensive patient assessment but are not specific to cultural considerations. While family history, chief complaint, and medical history are pertinent to understanding a patient's health status, health-related beliefs focus specifically on the cultural aspect that influences an individual's health perceptions and behaviors.
2. In the number 743.25, which digit represents the tenths place?
- A. 3
- B. 4
- C. 2
- D. 5
Correct answer: C
Rationale: In the number 743.25, the tenths place is the first digit to the right of the decimal point, which is 2. Therefore, the correct answer is C. Choice A (3) represents the hundredths place, choice B (4) represents the units place, and choice D (5) represents the hundredths place.
3. Another word for the collarbone might be the ___________.
- A. cloaca
- B. cannula
- C. clavicle
- D. clavier
Correct answer: C
Rationale: Another word for the collarbone is the clavicle. The term 'clavicle' is commonly used in anatomy to refer to this bone that connects the arm to the rest of the body's skeleton. Choice A, 'cloaca,' is incorrect as it refers to a bodily cavity that serves as the opening for the intestinal, genital, and urinary tracts in many vertebrates. Choice B, 'cannula,' is incorrect as it refers to a tube inserted into a vein or body cavity to administer medication or drain fluid. Choice D, 'clavier,' is incorrect as it refers to a keyboard musical instrument.
4. Which component is not found in the nucleotide of DNA?
- A. Simple sugar
- B. Nitrogen base
- C. Phosphate group
- D. Citric acid
Correct answer: D
Rationale: Citric acid is not found in the nucleotide of DNA. A DNA nucleotide is composed of a simple sugar (deoxyribose), a nitrogen base (adenine, thymine, cytosine, or guanine), and a phosphate group. Citric acid is not part of DNA nucleotides; instead, it is involved in the citric acid cycle of cellular respiration. Choices A, B, and C are essential components of DNA nucleotides, making them incorrect answers.
5. Select the word in the sentence that is not used correctly. The staunch hikers took a torturous downhill path that wound through thick vegetation.
- A. staunch
- B. torturous
- C. wound
- D. vegetation
Correct answer: C
Rationale: In the context of the sentence, the word 'wound' is not used correctly. It should be 'wove' instead of 'wound.' The correct word usage should be: 'The staunch hikers took a torturous downhill path that wove through thick vegetation.' 'Wound' is the past tense of 'wind,' while 'wove' is the past tense of 'weave,' which is the appropriate verb to describe a path navigating through vegetation. Choice A, 'staunch,' Choice B, 'torturous,' and Choice D, 'vegetation,' are all used appropriately in the sentence and do not contain any errors.
