• Question

The nurse is attending to a client who was diagnosed with heart failure. During the examination, the nurse observes that the client is dyspneic with crackles upon auscultation. Which symptoms would manifest for a client with excess fluid volume?• A. Decreased central venous pressure • B. Flat neck and hand veins • C. Hypertension • D. Weight loss Show Rationale

Correct:

• Hypertension is a sign of fluid volume excess or fluid overload. The increase in fluid volume causes an

increase in blood pressure in the vessels.

Incorrect:

A., B., D. Decreased central venous pressure, flat neck and hand veins, and weight loss are all signs of fluid volume deficit.

• Question

During the client’s medical records review, what condition can put the client at risk for developing hypokalemia?• A. Has a history of Addison’s disease • B. Nasogastric suction • C. Burn • D. Uric acid level of 10.2 mg/dL (59.48 µmol/L) Show Rationale

Correct:

• The client is at risk for hypokalemia due to losing potassium-rich gastrointestinal fluids during

nasogastric suction.

Incorrect: 1 / 2

A., C., D. Clients with tissue damage (such as from severe burns), hyperuricemia, and Addison’s disease are at risk for developing hyperkalemia. The normal uric acid level ranges from 2.7 to 8.5 mg/dL (160 to 501 µmol/L).

• Question

The nurse analyzes the electrolyte test results for a client and notes that the potassium level is 2.2 mEq/L (2.2 mmol/L). Based on the laboratory result, which ECG pattern is not expected?• A. Absent P waves • B. Depressed ST segment • C. Inverted T waves • D. Presence of U waves Show Rationale

Correct:

• A serum potassium level of 3.5 – 5.0 mEq/L (3.5-5.0 mmol/L) is considered normal. Hypokalemia is a

serum potassium level below 3.5 mEq/L (3.5 mmol/L). Absent P waves are not a sign of hypokalemia.However, it can be seen in a patient with ventricular rhythms, junctional rhythms, or atrial fibrillation.

Incorrect:

B., C., D. Shallow, flat, or inverted T waves, ST segment depression, and the presence of U waves are electrocardiographic alterations in hypokalemia.

• Question

An intravenous dose of potassium chloride is prescribed for a client with hypokalemia. Which action of the nurse indicates a need for further teaching in the preparation and administration of potassium?• A. Administer potassium through IV bolus.• B. Check if the label of the bag indicates the volume of the potassium in the solution.• C. Infuse potassium through an intravenous (IV) infusion pump.• D. Monitor urine output during infusion.Show Rationale

Correct:

• Never administer potassium chloride through bolus (IV push). Cardiac arrest may occur when

potassium chloride is injected intravenously as a bolus. The nurse needs to ensure that the potassium is diluted in the correct fluid or diluent.
