1. Among people who are ill, significant weight loss may be masked by?

A. dehydration
B. a large tumor
C. drug therapy
D. fluid retention

Correct answer: D

Rationale: Fluid retention can mask weight loss in ill individuals as the retained fluid adds to body weight, making it difficult to detect true fat or muscle loss. Dehydration (Choice A) would actually lead to weight loss rather than masking it. While a large tumor (Choice B) could contribute to weight loss, it would not mask the weight loss itself. Drug therapy (Choice C) may cause side effects, including weight changes, but it is unlikely to mask significant weight loss in the same way that fluid retention does.

2. Each of the following describes the physiologic roles of water, except one. Which is the exception?

A. Acts as a solvent for chemical reactions.
B. Maintains stability of body fluids.
C. Enables transport of nutrients and excretion of waste.
D. Regulates temperature by pooling as perspiration on skin.

Correct answer: D

Rationale: The correct answer is D. Water regulates body temperature by evaporating as perspiration from the skin, not by pooling. When sweat evaporates from the skin, it takes away heat, which helps cool the body. Choices A, B, and C are correct because water acts as a solvent for chemical reactions, maintains the stability of body fluids, and enables the transport of nutrients and excretion of waste, respectively.

3. Causes of acute renal failure include:

A. chronic renal failure
B. uncontrolled diabetes mellitus
C. recurrent urinary tract infections
D. severe injury such as extensive burns

Correct answer: D

Rationale: The correct answer is D. Severe injuries, like extensive burns, can cause acute renal failure due to shock, reduced blood flow to the kidneys, and tissue damage. Choices A, B, and C are incorrect because chronic renal failure, uncontrolled diabetes mellitus, and recurrent urinary tract infections are more likely to contribute to chronic kidney disease rather than acute renal failure.

4. What is the most likely demonstration of cardiac cachexia?

A. Decreased physical activity
B. Weight loss and tissue wasting
C. Poor urine output and tissue edema
D. Cardiac arrhythmia and wet lung sounds

Correct answer: B

Rationale: Cardiac cachexia is a condition characterized by severe weight loss and tissue wasting. This typically occurs in patients suffering from heart failure due to an increased energy expenditure and reduced appetite, which is why choice B is the correct answer. The other choices are incorrect as they do not accurately describe the symptoms of cardiac cachexia. Decreased physical activity (choice A) can be a result of many conditions, not specifically cardiac cachexia. Poor urine output and tissue edema (choice C) are more indicative of kidney problems rather than cardiac cachexia. Finally, cardiac arrhythmia and wet lung sounds (choice D) are symptoms related to other cardiac conditions, not specifically to cardiac cachexia.

5. Toilet training occurs in the anal stage of Freud’s psychosexual development. This is equivalent to Erikson’s:

A. Trust vs. Mistrust
B. Autonomy vs. Shame and Doubt
C. Initiative vs. Guilt
D. Industry vs. Inferiority

Correct answer: A

Rationale: The correct answer is A: Trust vs. Mistrust. In Freud's psychosexual development theory, the anal stage is where toilet training occurs, focusing on issues of control and independence. This stage is parallel to Erikson's Trust vs. Mistrust stage, where infants learn to trust or mistrust their caregivers based on the consistency of care they receive. Choices B, C, and D are incorrect as they correspond to different stages in Erikson's psychosocial development theory, not related to toilet training or the anal stage of Freud's theory.
