1. A nurse is assessing a client who has an electrolyte imbalance related to renal failure. For which potential complications of this electrolyte imbalance should the nurse assess? (Select all that do mot apply.)

A. Electrocardiogram changes
B. Slow, shallow respirations
C. Paralytic ileus
D. Skeletal muscle weakness

Correct answer: B

Rationale:

2. When does dehydration begin to occur?

A. the body reduces fluid output to zero.
B. the body increases the release of ANH.
C. the salivary secretions decrease.
D. the salivary secretions increase.

Correct answer: C

Rationale: Dehydration leads to a decrease in the body's fluid levels, causing the salivary glands to produce less saliva, resulting in a dry mouth. Therefore, when dehydration begins to occur, salivary secretions decrease. Choice A is incorrect because the body does not reduce fluid output to zero during dehydration; it tries to conserve fluids. Choice B is incorrect as dehydration does not directly increase the release of ANH (Atrial Natriuretic Hormone). Choice D is incorrect because salivary secretions do not increase but decrease during dehydration.

3. . One day after a patient is admitted to the medical unit, you note that the patient is oliguric. You notify the acutecare nurse practitioner who orders a fluid challenge of 200 mL of normal saline solution over 15 minutes. This intervention will achieve which of the following?

A. Help distinguish hyponatremia from hypernatremia
B. Help evaluate pituitary gland function
C. Help distinguish reduced renal blood flow from decreased renal function
D. Help provide an effective treatment for hypertension-induced oliguria

Correct answer: C

Rationale:

4. How would a decrease in blood protein concentration impact the fluid volumes?

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

Correct answer: D

Rationale: A decrease in blood protein concentration would lead to a reduction in osmotic pressure, which is responsible for drawing fluid back into the capillaries. This decrease in osmotic pressure would result in an increase in interstitial fluid volume as fluid moves out of the capillaries, and a decrease in blood plasma volume as less fluid is drawn back into the circulation. Therefore, the correct answer is to increase interstitial fluid volume and decrease blood plasma volume. Choices A, B, and C are incorrect because they do not reflect the impact of decreased blood protein concentration on fluid volumes.
