Nutrition and Fluid Balance Questions
Question 1 of 5
If a patient is experiencing alkalaemia, they are likely experiencing alkalosis as well.
Correct Answer: A
Rationale: The correct answer is A: TRUE. Alkalaemia refers to an elevated blood pH level, indicating alkalosis, which is a condition characterized by excessive alkalinity in body fluids. Alkalosis can result from various factors such as hyperventilation or excessive loss of acids. Therefore, if a patient is experiencing alkalaemia, they are likely experiencing alkalosis as well. The other choices are incorrect because they do not provide a logical explanation or rationale for the relationship between alkalaemia and alkalosis.
Question 2 of 5
The major source of H+ in the body fluids is the carbonic acid generated from metabolic production of CO .
Correct Answer: B
Rationale: Rationale: The major source of H+ in the body fluids is not carbonic acid from CO2, but rather metabolic processes generating H+ ions directly or through the dissociation of other acids. CO2 is converted to carbonic acid as part of the bicarbonate buffer system, which helps regulate pH but is not the primary source of H+ ions. Therefore, option B is correct. Option A is incorrect as explained above. Options C and D are not applicable as they are not choices related to the question.
Question 3 of 5
The kidneys secrete additional H+ and conserve HCO - to compensate for increased H+ concentration in the body fluids.
Correct Answer: A
Rationale: The correct answer is A because the statement aligns with the physiological process of renal compensation in response to increased acidity in the body. The kidneys secrete more H+ ions and conserve HCO3- to help maintain the body's pH within a normal range. This process helps to regulate acid-base balance. Choice B is incorrect because it contradicts the known function of the kidneys in maintaining acid-base balance. Choices C and D are not applicable as they do not provide any relevant information to address the question.
Question 4 of 5
H+ secretion is coupled to bicarbonate reabsorption.
Correct Answer: A
Rationale: The correct answer is A: TRUE. H+ secretion is coupled to bicarbonate reabsorption in the renal tubules. This process occurs in the proximal tubule of the nephron, where H+ ions are secreted into the tubular lumen in exchange for reabsorption of bicarbonate ions. This mechanism helps regulate blood pH by maintaining a balance between acid and base in the body. Other choices (B, C, D) are incorrect as they do not provide a valid explanation or relevant information related to the process of H+ secretion and bicarbonate reabsorption in the kidneys.
Question 5 of 5
A patient who is taking a potassium-wasting diuretic for treatment of hypertension reports generalized weakness. Which action is appropriate for the nurse to take?
Correct Answer: B
Rationale: The correct answer is B: Ask the patient about loose stools. Generalized weakness in a patient taking a potassium-wasting diuretic may indicate hypokalemia, which can be caused by excessive potassium loss through the kidneys. Loose stools can contribute to potassium loss. By asking about loose stools, the nurse can assess for potential potassium depletion and take appropriate action, such as monitoring potassium levels, adjusting medication dosage, or recommending dietary changes. Incorrect choices: A: Assess for facial muscle spasms - This is not directly related to generalized weakness in this context. C: Recommend the patient avoid drinking orange juice with meals - Orange juice is a good source of potassium and avoiding it may exacerbate potassium deficiency. D: Suggest that the health care provider order a basic metabolic panel - While this may provide information on electrolyte levels, directly addressing the potential cause of potassium loss through loose stools is more appropriate.
