1. Which of the following components is associated with hypertonic dehydration?

A. Plasma sodium levels above 150 mEq/L
B. Fluid moves from extracellular space to intracellular space
C. Water loss is greater than electrolyte loss
D. Physical signs and symptoms are grossly apparent

Correct answer: C

Rationale: The correct answer is 'Water loss is greater than electrolyte loss.' In hypertonic dehydration, there is a higher loss of water compared to electrolytes, leading to elevated concentrations of electrolytes in the body. This condition is characterized by plasma sodium levels above 150 mEq/L. As water moves from the extracellular space to the intracellular space, it results in cellular dehydration. Choice A is incorrect because the plasma sodium levels associated with hypertonic dehydration are typically above 150 mEq/L, not between 130 and 150 mEq/L. Choice B is incorrect as fluid moves from the extracellular space to the intracellular space in hypertonic dehydration. Choice D is incorrect because physical signs and symptoms may not always be grossly apparent in hypertonic dehydration.

2. A client is being monitored for decreased tissue perfusion and increased risk of skin breakdown. Which measure best improves tissue perfusion in this client?

A. Massaging the reddened areas
B. Performing range of motion exercises
C. Administering antithrombotics as ordered
D. Feeding the client a high-carbohydrate diet

Correct answer: B

Rationale: For a client at risk of impaired skin integrity due to decreased tissue perfusion, improving mobility is crucial to enhance tissue perfusion and prevent skin breakdown. Range of motion exercises are beneficial to increase circulation and prevent complications. Massaging reddened areas may further damage fragile skin. Administering antithrombotics may be necessary for specific conditions but does not directly address tissue perfusion. Feeding a high-carbohydrate diet does not directly improve tissue perfusion in this context.

3. Elderly patients are more prone to dehydration than younger people because the elderly ___________.

A. drink more coffee and tea
B. have more stomach mucus production
C. have more saliva
D. have less sense of thirst

Correct answer: D

Rationale: Elderly patients are prone to dehydration because they have a lower and diminished sense of thirst. This reduced sensation of thirst makes them less likely to drink an adequate amount of fluids, leading to dehydration. While it is true that elderly individuals may also have changes such as decreased stomach mucus production and saliva production, these factors do not directly contribute to dehydration. Drinking more coffee and tea, as mentioned in choice A, is not a consistent behavior among all elderly individuals and is not a primary reason for their increased risk of dehydration.

4. The client is being educated about depression by the nurse. Which statement by the client indicates that the teaching has been effective?

A. ''All elderly individuals experience depression occasionally.''
B. ''I'm relieved that I will improve within 2 or 3 days.''
C. ''I never realized depression could occur without a specific cause.''
D. ''Reducing stress in my life will alleviate the depression.''

Correct answer: C

Rationale: The correct answer, 'I never realized depression could occur without a specific cause,' demonstrates an understanding that depression can arise without a clear trigger, indicating effective teaching. Choice A is incorrect because not all elderly individuals experience depression, and this statement doesn't show understanding. Choice B is incorrect as it reflects a misconception about the quick resolution of depression. Choice D is incorrect as it oversimplifies the relationship between stress reduction and depression resolution.

5. You have noticed that the last several patients you have cared for have had questionable blood pressure readings from their arterial lines. When checked against cuff pressures, a discrepancy has been noted, and further investigation has revealed faulty transducers. This is not the first product issue with this company. What positive step could you take to help resolve this situation?

A. Use the old stock from a previous company
B. Verify the cuff pressures every hour to ensure accuracy
C. Notify the risk manager
D. Form a peer workgroup to evaluate new products

Correct answer: D

Rationale: Forming a peer workgroup to evaluate new products would be an excellent opportunity for collaboration among peers, management, and the purchasing department. When clinicians are engaged to work toward solutions that address patient care issues, they experience more empowerment and control over their work environments. Choice A is incorrect because using old stock from a previous company does not address the root cause of the faulty transducers from the current company. Choice B is incorrect as verifying cuff pressures every hour does not directly address the issue of faulty transducers. Choice C is less effective than forming a peer workgroup as it involves only notifying the risk manager without involving a collaborative effort to resolve the product issue.
