A nurse is collecting data about the fluid status of four clients. Which of the following clients should the nurse identify as being at risk for fluid volume deficit?

A client who has end-stage kidney disease who will undergo dialysis

A client who has gastroenteritis and is receiving oral fluids

A client who has heart failure and is receiving diuretic therapy

A client who has NPO status since midnight for an endoscopy

Answer and Explanation

The Correct Answer is B

A.   Clients with end-stage kidney disease often have impaired kidney function, leading to decreased urine output and retention of fluid and waste products. Dialysis is intended to remove excess fluid and waste from the body.
B.   Gastroenteritis involves inflammation of the gastrointestinal tract, leading to symptoms such as diarrhea and vomiting. These symptoms result in significant fluid loss.
C.   Heart failure can lead to fluid retention and edema due to the heart's inability to pump effectively. Diuretic therapy is commonly prescribed to manage fluid overload by increasing urine output. However, excessive diuresis or inadequate intake of fluids can lead to fluid volume deficit, particularly if the client does not compensate with adequate oral intake.

D.   This client has been NPO only since midnight (about 9–14 hours, depending on procedure time). While intake is restricted, this short period is not usually enough to cause a significant fluid volume deficit, unless prolonged.

Correct Answer is A

Explanation

A. Positioning the client's arm above heart level can result in a falsely low blood pressure reading. This is because gravity assists in the flow of blood downward, artificially reducing the pressure measured in the arteries. For accurate blood pressure measurement, the client's arm should be positioned at heart level or slightly below heart level.
B. If the blood pressure cuff is wrapped too loosely around the client's arm, it can lead to inaccurate readings. A loose cuff may allow leakage of air during inflation or may not provide sufficient compression to accurately detect the arterial pressure pulses.
C. Deflating the cuff too slowly can cause a falsely high diastolic pressure reading. When the cuff is deflated slowly, the pressure in the cuff remains close to the systolic pressure for a longer duration, leading to incorrect readings, especially in diastolic pressure.
Blood pressure can temporarily increase after meals due to digestion, particularly in clients with hypertension. Measuring blood pressure immediately after a meal may result in a higher reading that does not reflect the client's baseline blood pressure. However, this would typically lead to a higher reading rather than a lower one.

Correct Answer is ["0.1"]

Explanation

(desired dose ÷ available concentration) = amount to administer.

For a desired dose of 5 mg and an available concentration of 50 mg/mL, the calculation would be 5 mg ÷ 50 mg/mL = 0.1 mL.

Therefore, the nurse should administer 0.1 mL per dose.
