1. 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.

2. What is a likely effect on a patient whose lab results reveal hypoalbuminemia?

A. Infection
B. Rickets
C. Hypertension
D. Edema

Correct answer: D

Rationale: Hypoalbuminemia, which refers to low albumin levels in the blood, is often associated with edema. Albumin helps maintain oncotic pressure, which keeps fluid within blood vessels. When albumin levels are low, this pressure decreases, leading to fluid leakage from the blood vessels into the surrounding tissues, resulting in edema. The other choices are less likely effects of hypoalbuminemia. Hypoalbuminemia doesn't directly cause infections (Choice A), rickets (Choice B) caused by vitamin D deficiency, or hypertension (Choice C) associated with factors like high sodium intake, obesity, and genetic predisposition.

3. To successfully complete the tasks of older adulthood, an 85 year old who has been a widow for 25 years should be encouraged to:

A. Invest her creative energies in promoting social welfare
B. Redefine her role in the society and offer something and offer something of value
C. Feel a sense of satisfaction in reflecting on her productive life
D. Look to recapture the opportunities that were never started or completed

Correct answer: D

Rationale: Understanding the underlying pathology and therapeutic techniques ensures that nursing care is not only reactive but also preventative, reducing the risk of complications.

4. Each statement regarding the correlation between vitamin D and sun exposure is accurate, except one. Which is the exception?

A. The body can produce sufficient amounts of vitamin D from sunlight.
B. UV radiation can convert a precursor of vitamin D to vitamin D3 by penetrating uncovered skin.
C. Sunscreen blocks the formation of vitamin D3.
D. By the age of 70 years, the skin generally produces vitamin D at only half the level it did at the age of 20 years.

Correct answer: C

Rationale: While UV radiation can penetrate uncovered skin and convert a precursor of vitamin D to vitamin D3, sunscreen does block the formation of vitamin D3. Sunscreen is recommended by dermatologists to prevent sunburn and reduce the risk of skin cancer. The other choices are correct: the body can produce sufficient vitamin D from sunlight, UV radiation can convert a precursor of vitamin D to vitamin D3, and skin generally produces less vitamin D as a person ages.
