The nurse assesses that a client who is disoriented drank eight glasses of water in two hours and is continuing to drink excessive amounts of water. Because the nurse is concerned about water intoxication, which laboratory value should the nurse monitor?

White blood cell count.

Serum sodium levels.

Serum potassium levels.

Creatinine clearance.

Answer and Explanation

The Correct Answer is B

A. White blood cell count is related to immune function and is not directly affected by water intoxication.
B. Serum sodium levels are the primary concern in cases of water intoxication. Excessive water intake can dilute the sodium in the blood, leading to hyponatremia, which can cause confusion, seizures, and other serious complications.
C. While serum potassium levels are important for overall electrolyte balance, they are not as immediately affected by water intoxication as sodium levels are.
D. Creatinine clearance is a measure of kidney function and does not directly relate to the immediate risks associated with water intoxication.

Correct Answer is B

Explanation

A. The use of "2.0 mg" is incorrect because trailing zeros can lead to dosage errors. The correct documentation should avoid trailing zeros to prevent misinterpretation.
B. "Morphine 2 mg IV every 4 hr PRN for severe pain" is the correct format. It uses the full name of the drug, avoids abbreviations that could be confused, and follows best practices for documenting as-needed (PRN) medications.
C. Using "MS" instead of "morphine" is not recommended because "MS" can be confused with magnesium sulfate or other medications. The full drug name should always be used.
D. Similar to option A, the use of "2.0 mg" includes a trailing zero, which should be avoided to reduce the risk of errors in medication administration.

A. Paper mask and gown. B. A sputum specimen. C. The nurse's stethoscope. D. Bed linens.

Correct Answer is A

Explanation

A. Paper masks and gowns used for isolation precautions should be placed in a designated biohazard bag before removal from the room. These items are considered contaminated and must be disposed of according to infection control protocols.
B. A sputum specimen should be placed in a sealed, labeled container before being transported to the lab, not in a biohazard bag for disposal.
C. The nurse's stethoscope should be disinfected but does not need to be disposed of unless it is single-use.
D. Bed linens are typically placed in a laundry bag specifically designated for contaminated linens, not in a biohazard bag.
