ATI Fluid Electrolyte and Acid-Base Regulation
1. You are the nurse evaluating a newly admitted patients laboratory results, which include several values that are outside of reference ranges. Which of the following would cause the release of antidiuretic hormone (ADH)?
- A. Increased serum sodium
- B. Decreased serum potassium
- C. Decreased hemoglobin
- D. Increased platelets
Correct answer: A
Rationale:
2. Which hormone reduces the amount of water in the body?
- A. ADH
- B. aldosterone
- C. ANH
- D. ADH and aldosterone
Correct answer: B
Rationale: The correct answer is 'aldosterone.' Aldosterone is the hormone that reduces the amount of water in the body by increasing the reabsorption of sodium and water from the kidney tubules. ANH (atrial natriuretic hormone) actually works to increase the excretion of sodium and water by the kidneys, leading to a reduction in blood volume and pressure. ADH (antidiuretic hormone) works to increase water reabsorption by the kidneys, thereby increasing blood volume. Therefore, choices A (ADH) and D (ADH and aldosterone) are incorrect in the context of reducing the amount of water in the body.
3. A nurse is assessing a client with hypokalemia and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first?
- A. Assess the client's respiratory rate, rhythm, and depth.
- B. Measure the client's pulse and blood pressure.
- C. Document findings and monitor the client.
- D. Call the healthcare provider.
Correct answer: A
Rationale: In a client with hypokalemia experiencing diminished handgrip strength, the priority action for the nurse is to assess the client's respiratory rate, rhythm, and depth. Hypokalemia can lead to muscle weakness, including respiratory muscles, potentially causing respiratory distress. Assessing the respiratory status is crucial to determine if immediate interventions are needed to maintain adequate oxygenation. Measuring the client's pulse and blood pressure (Choice B) is important but should come after assessing the respiratory status. Simply documenting findings and monitoring the client (Choice C) may delay necessary interventions. Calling the healthcare provider (Choice D) is not the first action indicated in this situation; assessing the client's respiratory status takes precedence.
4. A nurse assesses a client who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications should the nurse assess? (Select all that apply.)
- A. Urine output of 25 mL/hr
- B. Serum potassium level of 5.4 mEq/L
- C. Blood osmolality of 250 mOsm/L
- D.
Correct answer: A
Rationale:
5. Which of the following organs does not contribute to fluid output from the body?
- A. Lungs
- B. Skin
- C. Intestine
- D. Lungs, skin, and intestine
Correct answer: D
Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.
