What is the meaning of the word 'maladroit' in the sentence: 'Those who are maladroit should not become surgeons'?
- A. Clumsy
- B. Romantic
- C. Untrained
- D. Self-conscious

The abbreviation LBW on an infant's chart refers to the baby's ___________.
- A. genetic makeup
- B. feeding schedule
- C. Babinski response
- D. weight at birth
Correct Answer: D
Rationale: The abbreviation LBW stands for 'Low Birth Weight,' which specifically refers to the weight of the infant at birth. It is an important indicator of the baby's health and development, with low birth weight infants often requiring special medical attention and care. Choices A, B, and C are incorrect because LBW does not relate to genetic makeup, feeding schedule, or Babinski response; rather, it is a term used to describe infants who are born weighing less than normal, which can have implications for their health and require additional monitoring and support.
Choose the meaning of the word 'tremulous' in the following sentence: 'The patient held out a tremulous hand and grasped the paperwork.'
- A. Wrinkled and wizened
- B. Pale and lifeless
- C. Clenched and arthritic
- D. Quivering and weak
Correct Answer: D
Rationale: In this sentence, the word 'tremulous' is used to describe the patient's hand. When someone's hand is described as tremulous, it means it is quivering or shaking, indicating weakness or distress. Therefore, the correct meaning of 'tremulous' in this context is quivering and weak. Choices A, B, and C are incorrect because they do not capture the specific meaning of 'tremulous' in this context. 'Wrinkled and wizened' refers to being old and withered, 'pale and lifeless' describes a lack of color and vitality, and 'clenched and arthritic' implies a tight grip and joint inflammation, none of which accurately represent the trembling or shaking nature of a tremulous hand.
Select the meaning of the word 'corpulence' in the sentence: 'The patient's corpulence made him difficult to handle.'
- A. Belligerence
- B. Gassiness
- C. Wariness
- D. Stoutness
Correct Answer: D
Rationale: The correct answer is D: 'Stoutness.' The word 'corpulence' refers to the state of being excessively fat or overweight, indicating the patient's stoutness or large size due to excess body weight. Choice A, 'Belligerence,' is incorrect as it means aggressive or hostile behavior, which does not fit the context of the sentence. Choice B, 'Gassiness,' is incorrect as it refers to the state of having excessive gas in the digestive system, which is unrelated to the patient's physical size. Choice C, 'Wariness,' is incorrect as it means cautiousness or being alert, which is not relevant to the patient's physical appearance described in the sentence.

'Infested' means being invaded by pests, 'Fatiguing' means causing tiredness or exhaustion, and 'Supplementing' means adding to or enhancing something, none of which accurately describe the term 'cathartic.'
