Question 1 of 5

The nurse is caring for a patient who is diaphoretic from a fever. The amount of sodium excreted in the urine will:

Correct Answer: A

Rationale: Increased sweating (diaphoresis) leads to the loss of sodium and other electrolytes, resulting in higher sodium excretion in the urine.

Question 2 of 5

The nurse preparing a site for the insertion of an IV catheter should treat excess hair at the site by:

Correct Answer: C

Rationale: Hair can be a source of infection and should be removed by clipping. Shaving the area can cause skin abrasions, and depilatories can irritate the skin.

Question 4 of 5

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

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.

Question 5 of 5

A nurse in the medical-surgical unit has a newly admitted patient who is oliguric; the acute care nurse practitioner orders a fluid challenge of 100 to 200 mL of normal saline solution over 15 minutes. The nurse is aware this intervention will help:

Correct Answer: C

Rationale: If a patient is not excreting enough urine, the health care provider needs to determine whether the depressed renal function is the result of reduced renal blood flow, which is a fluid Volume deficit (FVD) or prerenal azotemia, or acute tubular necrosis that results in necrosis or cellular death from prolonged FVD. A typical example of a fluid challenge involves administering 100 to 200 mL of normal saline solution over 15 minutes. The response by a patient with FVD but normal renal function is increased urine output and increased blood pressure.
