1. The healthcare professional is preparing to administer potassium chloride intravenously to a client with hypokalemia. Which action is most important?

Correct answer: D

Rationale: The correct answer is to dilute the potassium chloride in an appropriate IV solution. Potassium chloride should never be administered as a rapid IV push as it can lead to severe complications, including cardiac arrhythmias. Diluting the medication and administering it slowly helps reduce the risk of adverse effects. Monitoring the client's respiratory rate (Choice A) and checking urine output (Choice B) are important aspects of patient assessment but not the most crucial when administering potassium chloride. Administering potassium chloride as a rapid IV push (Choice C) is dangerous and can result in serious harm to the client.

2. A healthcare professional is administering 1 L of 0.9% sodium chloride to a client who is postoperative and has fluid-volume deficit. Which of the following changes should the healthcare professional identify as an indication that the treatment was successful?

Correct answer: C

Rationale: Fluid-volume deficit causes tachycardia. With correction of the imbalance, the heart rate should return to the expected range. An increase in hematocrit (Choice A) would indicate hemoconcentration, not a successful fluid replacement. An increase in respiratory rate (Choice B) could indicate respiratory distress or hypoxia, not improvement in fluid volume status. A decrease in capillary refill time (Choice D) may indicate improved peripheral perfusion but is not a direct indicator of fluid replacement success.

3. A client has been admitted to the hospital with severe diarrhea. The nurse should monitor the client for which complication?

Correct answer: A

Rationale: Severe diarrhea can lead to metabolic acidosis due to the loss of bicarbonate. When there is excessive loss of bicarbonate through diarrhea, the pH of the blood decreases, leading to metabolic acidosis. Metabolic alkalosis (Choice B) is not typically associated with severe diarrhea as it involves elevated pH and bicarbonate levels. Hyperkalemia (Choice C) is less likely with severe diarrhea as potassium is often lost along with fluids. Hypercalcemia (Choice D) is not a common complication of severe diarrhea; instead, hypocalcemia may occur due to malabsorption of calcium.

4. The healthcare provider is assessing a client with a history of congestive heart failure. Which assessment finding would be most concerning?

Correct answer: D

Rationale: Crackles in the lungs are concerning because they indicate pulmonary congestion, a serious complication of congestive heart failure. The presence of crackles suggests fluid accumulation in the lungs, requiring immediate attention to prevent respiratory distress and worsening heart failure. While shortness of breath on exertion, weight gain, and orthopnea are common signs and symptoms of heart failure, crackles specifically point to acute pulmonary edema or worsening congestion, making them the most concerning finding in this scenario.

5. A healthcare professional is caring for a group of clients. Which of the following measures should the professional take to prevent the spread of infection?

Correct answer: A

Rationale: Tuberculosis is an airborne infection, and placing a client with TB in a room with negative pressure airflow helps prevent the spread of the infection by containing the pathogens. This measure is crucial as it prevents the dissemination of TB droplet nuclei to other areas. Choice B, using a disposable gown for contact precautions, is important for preventing the transmission of infections spread by direct or indirect contact. Choice C, placing a client with MRSA in a private room, is essential to prevent the spread of MRSA through contact with others. Choice D, using a mask for clients with influenza, helps prevent the spread of influenza through respiratory droplets. However, negative pressure airflow is specifically required for airborne infections like TB, making it the most appropriate choice in this scenario.
