1. When a child jumps out of the tub, crying and stating her feet are 'burning,' what pathophysiologic principle is responsible for this response?

• A. Pain receptors (nociceptors) have been activated in response to a thermal stimulus.
• B. The child's skin thermal receptors have undergone adaptation.
• C. The child is exhibiting a psychogenic pain response due to anxiety.
• D. The child is experiencing a conditioned pain response based on previous experiences.

Correct answer: A

Rationale: The child's reaction is due to the activation of nociceptors, which are pain receptors that respond to thermal stimuli. This response is an immediate protective mechanism to prevent tissue damage caused by extreme temperatures. Option B is incorrect because adaptation does not explain the child's immediate and intense response. Option C is incorrect as there is a clear physical stimulus present, ruling out a psychogenic response. Option D is incorrect as the child's response is not based on previous experiences but rather on the current thermal stimulus.

2. A male patient with benign prostatic hyperplasia (BPH) is prescribed finasteride (Proscar). What is the expected therapeutic effect of this medication?

• A. Decreased urinary frequency and urgency
• B. Decreased blood pressure
• C. Increased urinary output
• D. Increased hair growth

Correct answer: A

Rationale: The correct answer is A: Decreased urinary frequency and urgency. Finasteride is used to reduce the size of the prostate gland in patients with BPH, which helps alleviate symptoms such as urinary frequency and urgency. Choice B, decreased blood pressure, is incorrect because finasteride is not indicated for lowering blood pressure. Choice C, increased urinary output, is incorrect as finasteride does not typically increase urine production. Choice D, increased hair growth, is incorrect as the primary use of finasteride is not for promoting hair growth but rather for treating BPH.

3. Which of the following disturbances would cause a client to experience gout?

• A. Serotonin receptors
• B. Uric acid metabolism
• C. Liver function
• D. Cardiac function

Correct answer: B

Rationale: Gout is caused by a disturbance in uric acid metabolism, leading to the accumulation of uric acid crystals in joints. Serotonin receptors (Choice A) are not related to gout. Liver function (Choice C) is important for metabolism but is not directly linked to gout development. Cardiac function (Choice D) is primarily related to the heart's functioning and not associated with gout.

4. A student nurse was asked which of the following best describes dementia. Which of the following best describes the condition?

• A. Memory loss as a natural consequence of aging
• B. Difficulty coping with physical and psychological changes
• C. Severe cognitive impairment that occurs rapidly
• D. Loss of cognitive abilities, impairing the ability to perform activities of daily living

Correct answer: D

Rationale: The correct answer is D. Dementia is characterized by a loss of cognitive abilities that impairs the individual's capacity to perform activities of daily living. Choice A is incorrect because dementia is not simply memory loss related to aging but involves broader cognitive deficits. Choice B is incorrect as it does not capture the comprehensive cognitive decline seen in dementia. Choice C is incorrect as dementia typically progresses gradually rather than rapidly, and it is not solely about severe cognitive impairment but also impacts daily functioning.

5. If the client's dorsal columns are not functioning, the nurse will observe which response during neuro testing, where the nurse asks the client to close his eyes and then proceeds to touch corresponding parts of the body on each side simultaneously with two sharp points?

• A. The client will not be able to distinguish between the two points.
• B. The client will feel only one point of contact.
• C. The client will accurately identify both points.
• D. The client will report no sensation in the touched areas.

Correct answer: A

Rationale: If the client's dorsal columns are not functioning, the ability to distinguish between two closely spaced points is impaired. This results in the client not being able to differentiate between the two points when touched simultaneously. Choice B is incorrect because the client feeling only one point suggests an intact dorsal column function. Choice C is incorrect as accurately identifying both points indicates normal discrimination ability. Choice D is incorrect as reporting no sensation does not correspond to the specific impairment related to dorsal column dysfunction.
