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. An increase in capillary blood pressure would tend to:

A. increase interstitial fluid volume.
B. increase plasma volume.
C. decrease interstitial fluid volume.
D. increase plasma volume and decrease interstitial fluid volume.

Correct answer: A

Rationale: An increase in capillary blood pressure leads to a higher force pushing fluid out of the capillaries into the interstitial space, thereby increasing interstitial fluid volume. Choice B is incorrect because capillary blood pressure affects the movement of fluid into the interstitial space, not into the plasma. Choice C is incorrect as an increase in capillary blood pressure would not decrease interstitial fluid volume. Choice D is incorrect as it combines contradictory effects when capillary blood pressure increases.

3. .A nurse assesses a clients peripheral IV site, and notices edema and tenderness above the site. Which action should the nurse take next?

A. Apply cold compresses to the IV site.
B. Elevate the extremity on a pillow.
C. Flush the catheter with normal saline.
D. . Stop the infusion of intravenous fluids.

Correct answer: D

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. When selecting a site on the hand or arm for insertion of an IV catheter, the nurse should:

A. Choose a proximal site.
B. Choose a distal site.
C. Have the patient hold their arm in a dependent position.
D. Leave the tourniquet on for no longer than 2 minutes.

Correct answer: B

Rationale: When selecting a site for insertion of an IV catheter, the nurse should choose a distal site, not a proximal site. Opting for a distal site ensures that upper veins remain available for future cannulations. Instructing the patient to hold their arm in a dependent position can enhance blood flow, aiding in the procedure. It is crucial never to leave a tourniquet on for more than 2 minutes as prolonged restriction can lead to complications. Choice A is incorrect because a proximal site is not preferred for IV insertion. Choice C is incorrect as having the patient hold their arm over their head is not necessary and may impede proper blood flow. Choice D is incorrect as leaving the tourniquet on for at least 5 minutes is excessive and can be harmful.
