Nursing Elites

1. The nurse assessing skin turgor in an elderly patient should remember that:

• A. Overhydration causes the skin to tent.
• B. Dehydration causes the skin to appear edematous and spongy.
• C. Inelastic skin turgor is a normal part of aging.
• D. Normal skin turgor is moist and boggy.

Correct answer: C

Rationale: Inelastic skin turgor is a normal part of aging. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Normal skin turgor is dry and firm. Choice A is incorrect because overhydration does not cause the skin to tent; it is dehydration that leads to tenting. Choice B is incorrect because dehydration, not overhydration, causes the skin to appear edematous and spongy. Choice D is incorrect because normal skin turgor is dry and firm, not moist and boggy.

2. A nurse sees a variety of patients in the community health clinic. Which of the following patients would be at the greatest risk of dehydration?

• A. An 18-year-old basketball player with a stress fracture of the right foot
• B. An infant with diarrhea
• C. A 45-year-old with stomach flu
• D. An elderly patient living alone

Correct answer: B

Rationale: The correct answer is B. Infants are particularly vulnerable to dehydration due to diarrhea because they have a higher fluid turnover and less reserve. Option A, the 18-year-old basketball player with a stress fracture, is less likely to be at the greatest risk of dehydration compared to an infant with diarrhea. Option C, the 45-year-old with stomach flu, may experience dehydration but is not at the same level of risk as an infant with diarrhea. Option D, the elderly patient living alone, could be at risk of dehydration, but infants with diarrhea are at the greatest risk due to their unique physiological characteristics.

3. . A nurse is planning care for a nephrology patient with a new nursing graduate. The nurse states, A patient in renal failure partially loses the ability to regulate changes in pH. What is the cause of this partial inability?

• A. The kidneys regulate and reabsorb carbonic acid to change and maintain pH.
• B. The kidneys buffer acids through electrolyte changes
• C. The kidneys regenerate and reabsorb bicarbonate to maintain a stable pH.
• D. The kidneys combine carbonic acid and bicarbonate to maintain a stable pH.

Correct answer: C

Rationale:

4. Who would have the greatest percentage of body water?

• A. an obese male
• B. a nonobese male
• C. a nonobese female
• D. a newborn

Correct answer: D

Rationale: Newborns have a higher percentage of body water compared to adults due to their higher body fluid content. Factors such as the higher ratio of body surface area to body volume and lower body fat content contribute to this. This is why a newborn would have the greatest percentage of body water. Choices A, B, and C are incorrect because obesity and gender do not determine the percentage of body water in individuals. Therefore, the correct answer is a newborn.

• A. Provide a bed bath instead of letting the client take a shower
• B. Use sterile technique when changing the dressing.
• C. Disconnect the intravenous fluid tubing prior to the clients bath.
