ATI Fluid Electrolyte and Acid-Base Regulation

1. After teaching a client who was malnourished and is being discharged, a nurse assesses the clients understanding. Which statement indicates the client correctly understood teaching to decrease risk for the development of metabolic acidosis?

Correct answer: A

Rationale:

2. A nurse is caring for a client who has the following laboratory results: potassium 3.4 mEq/L, magnesium 1.8 mEq/L, calcium 8.5 mEq/L, sodium 144 mEq/L. Which assessment should the nurse complete first?

Correct answer: A

Rationale: The correct answer is 'Depth of respirations.' In a client with electrolyte imbalances like low potassium (hypokalemia) and low magnesium (hypomagnesemia), respiratory changes, such as shallow respirations or respiratory muscle weakness, can occur and lead to respiratory compromise. Assessing the depth of respirations is crucial to evaluate respiratory function in this client. Bowel sounds, grip strength, and electrocardiography are also important assessments in different situations, but in this case, respiratory assessment takes priority due to the potential impact of electrolyte imbalances on breathing.

3. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

Correct answer: B

Rationale:

4. A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

Correct answer: B

Rationale:

5. What is the most important regulator of the amount of sodium in the body?

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys play a crucial role in regulating the amount of sodium in the body. They achieve this by filtering blood and controlling the excretion or reabsorption of sodium. The small intestine is primarily responsible for nutrient absorption, not sodium regulation. The large intestine is mainly involved in water absorption and waste elimination, not sodium balance. The skin helps regulate body temperature through sweating and does not directly regulate sodium levels.
