ATI Fluid and Electrolytes
1. Which mineral is important in hemoglobin production?
- A. Sodium
- B. Iodine
- C. Iron
- D. Chloride
Correct answer: C
Rationale: Iron (Fe) is a critical mineral in hemoglobin production. Hemoglobin is a protein found in red blood cells that is essential for transporting oxygen throughout the body. Sodium (Choice A), Iodine (Choice B), and Chloride (Choice D) are not directly involved in hemoglobin production. Sodium is an electrolyte that helps maintain fluid balance, Iodine is essential for thyroid hormone production, and Chloride is an electrolyte that helps regulate fluid balance and acidity in the body.
2. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?
- A. Choose a site with minimal hair if available.
- B. Consider potential effects on the patient's mobility when selecting a site.
- C. Instruct the patient to hold his arm in a dependent position before insertion.
- D. Remove the tourniquet after 2 minutes.
Correct answer: B
Rationale: When selecting a site for IV insertion on the hand or arm, it is important to consider the potential effects on the patient's mobility. The chosen site should not interfere with the patient's movement. Instructing the patient to hold his arm in a dependent position helps increase blood flow, aiding in vein visualization and insertion. It is advisable to choose a site with minimal hair if possible for better adhesion of the dressing. Removing the tourniquet after 2 minutes is recommended to prevent complications like hemoconcentration and potential vein damage. Therefore, option B is the correct choice as it aligns with best practices for IV insertion.
3. A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications
- A. Initiate a dedicated team to insert access devices
- B. . Require additional education for all nurses.
- C. Limit the use of peripheral venous access devices.
- D. Perform quality control testing on skin preparation products.
Correct answer: A
Rationale:
4. The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?
- A. Respiratory acidosis
- B. Respiratory alkalosis
- C. Metabolic acidosis
- D. Metabolic alkalosis
Correct answer: B
Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation is the most common cause of acute respiratory alkalosis. When a patient hyperventilates due to anxiety or other causes, they blow off excessive carbon dioxide, leading to a decrease in PaCO2 and a rise in pH. Choices A, C, and D are incorrect because hyperventilation leads to a decrease in PaCO2, causing respiratory alkalosis, not respiratory acidosis, metabolic acidosis, or metabolic alkalosis.
5. 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.
