1. You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patient's skin turgor?

A. Overhydration is common among healthy older adults.
B. Dehydration causes the skin to appear spongy.
C. Inelastic skin turgor is a normal part of aging.
D. Skin turgor cannot be assessed in patients over 70.

Correct answer: C

Rationale: Inelastic skin is a normal change of aging. However, this does not mean that skin turgor cannot be assessed in older patients. Dehydration, not overhydration, causes inelastic skin with tenting. Overhydration, not dehydration, causes the skin to appear edematous and spongy. Choice A is incorrect because overhydration is not common among healthy older adults. Choice B is incorrect because dehydration leads to inelastic skin, not sponginess. Choice D is incorrect as skin turgor assessment can be done in patients of any age, including those over 70.

2. A nurse evaluates the following arterial blood gas values in a client: pH 7.48, PaO2 98 mm Hg, PaCO2 28 mm Hg, and HCO3 22 mEq/L. Which client condition should the nurse correlate with these results?

A. Diarrhea and vomiting for 36 hours
B. . Anxiety-induced hyperventilation
C. Chronic obstructive pulmonary disease (COPD)
D. Diabetic ketoacidosis and emphysema

Correct answer: B

Rationale:

3. A nurse teaches a client who is prescribed a central vascular access device. Which statement should the nurse include in this clients teaching?

A. You will need to wear a sling on your arm while the device is in place
B. There is no risk of infection because sterile technique will be used during insertion.
C. . Ask all providers to vigorously clean the connections prior to accessing the device.
D. You will not be able to take a bath with this vascular access device.

Correct answer: C

Rationale:

4. What is the main force that pushes fluid in blood capillaries?

A. Blood pressure.
B. Sodium in the blood plasma.
C. Sodium in the interstitial fluid.
D. Protein in the blood plasma.

Correct answer: A

Rationale: The correct answer is A, blood pressure. Blood pressure is the primary force that pushes fluid out of the capillaries into the surrounding tissues. This pressure difference is essential for the exchange of nutrients, gases, and waste products between the blood and tissues. Choices B, C, and D are incorrect as they do not represent the primary force responsible for pushing fluid in blood capillaries.

5. What percentage of body water can be as high as in a newborn?

A. 80%.
B. 70%.
C. 60%.
D. 90%.

Correct answer: A

Rationale: The correct answer is A: 80%. Newborns can have a body water content as high as 80% due to their higher total body water compared to adults. Choice B (70%) is incorrect because newborns typically have a higher body water percentage. Choice C (60%) is also incorrect as it underestimates the body water content in newborns. Choice D (90%) is incorrect as it overestimates the body water percentage in newborns.
