1. Which of the following are sources of water intake?

• A. Drinking fluids.
• B. Consuming water from the food we eat.
• C. Water from metabolic processes.
• D. Drinking fluids, consuming water from the food we eat, and water from metabolic processes.

Correct answer: D

Rationale: The correct answer is D. The sources of water intake include drinking fluids, consuming water from the food we eat, and water from metabolic processes. Water intake is not solely from the liquids we drink but also from the water content present in the food we consume and the water produced during metabolic processes such as cellular respiration. Therefore, option D is the correct answer as it covers all the sources of water intake. Options A, B, and C alone do not encompass all the sources of water intake, making them incorrect choices.

2. . A nurse is planning care for a nephrology patient with a new nursing graduate. The nurse states, A patient in renal failure partially loses the ability to regulate changes in pH. What is the cause of this partial inability?

• A. The kidneys regulate and reabsorb carbonic acid to change and maintain pH.
• B. The kidneys buffer acids through electrolyte changes
• C. The kidneys regenerate and reabsorb bicarbonate to maintain a stable pH.
• D. The kidneys combine carbonic acid and bicarbonate to maintain a stable pH.

Correct answer: The kidneys regenerate and reabsorb bicarbonate to maintain a stable pH.

3. A patient is taking spironolactone (Aldactone) to control her hypertension. Her serum potassium level is 6 mEq/L. For this patient, the nurse's priority would be to assess her:

• A. Neuromuscular function
• B. Bowel sounds
• C. Respiratory rate
• D. Electrocardiogram (ECG) results

Correct answer: D

Rationale: In a patient with a serum potassium level of 6 mEq/L due to spironolactone use, the nurse's priority is to assess the Electrocardiogram (ECG) results. Hyperkalemia can lead to life-threatening arrhythmias, such as ventricular fibrillation, which can be detected on an ECG. While changes in neuromuscular function, bowel sounds, and respiratory rate can occur with hyperkalemia, the most critical assessment related to the patient's condition would be monitoring the ECG for signs of cardiac complications.

4. You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patient's plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to assess what aspect of the patient's health?

• A. Nutritional status
• B. Potassium balance
• C. Calcium balance
• D. Fluid volume status

Correct answer: D

Rationale: Assessing the specific gravity in a patient with SIADH helps the nurse evaluate the patient's fluid volume status. Specific gravity indicates the concentration of solutes in the urine and can detect if the patient has a fluid volume deficit or excess. Nutritional status, potassium balance, and calcium balance are not directly assessed through specific gravity testing. Nutritional status is typically evaluated through dietary intake and anthropometric measurements. Potassium balance is assessed through blood tests and ECG monitoring. Calcium balance is evaluated through blood tests and bone density scans. Therefore, the correct answer is assessing fluid volume status through specific gravity testing.

5. The healthcare provider is evaluating a patient's laboratory results. Based on the laboratory findings, what results will cause the release of an antidiuretic hormone (ADH)?

• A. Increased serum sodium
• B. Decreased serum sodium
• C. Decrease in serum osmolality
• D. Decrease in thirst

Correct answer: A

Rationale: The correct answer is A: Increased serum sodium. When serum sodium levels increase, it triggers the release of ADH by the posterior pituitary gland. ADH helps in retaining water, reducing urine output, and maintaining fluid balance. Choices B, C, and D are incorrect because decreased serum sodium, decrease in serum osmolality, and decrease in thirst do not stimulate the release of ADH.
