ATI Fluid Electrolyte and Acid-Base Regulation

Correct Answer: D

Rationale: The correct answer is D because using a plastic bag to cover the extremity with the device helps to keep the area dry when bathing, preventing the tourniquet from becoming wet and losing its effectiveness. This technique maintains the pressure needed for venipuncture. A, providing a bed bath instead of a shower, is unrelated to the use of a tourniquet. B, using sterile technique for dressing changes, is important for wound care but not relevant to tourniquet use. C, disconnecting intravenous fluid tubing before a bath, is essential for preventing contamination but not directly related to tourniquet management.

Correct Answer: A

Rationale: The correct answer is A: "I will drink at least three glasses of milk each day." Milk is a good source of calcium and bicarbonate, which can help buffer excess acids in the body and prevent metabolic acidosis. Calcium also plays a role in maintaining the acid-base balance. Option B is incorrect because while eating well-balanced meals is important for overall health, it does not specifically address the prevention of metabolic acidosis. Option C is irrelevant to the prevention of metabolic acidosis. Option D is incorrect because avoiding salting food does not directly address the underlying issue of metabolic acidosis related to malnutrition.

Correct Answer: C

Rationale: The correct answer is C: Metabolic alkalosis. Pyloric stenosis can lead to vomiting, causing loss of gastric acid and chloride ions, leading to metabolic alkalosis. Low potassium levels are common in metabolic alkalosis due to potassium shifting into cells to compensate for the alkalosis. Hypercalcemia (choice A) is not associated with pyloric stenosis. Metabolic acidosis (choice B) typically presents with low pH and bicarbonate levels. Respiratory acidosis (choice D) is caused by impaired gas exchange in the lungs, not related to pyloric stenosis.

Correct Answer: B

Rationale: The correct answer is B: Administer the prescribed medication. The nurse has assessed the client's site and reviewed the chart, indicating readiness to administer the medication. It is crucial to follow the healthcare provider's order and administer the prescribed medication as planned. Notifying the provider (A) is unnecessary if all assessments are normal. Discontinuing the PICC line (C) without a valid reason can lead to complications. Switching to oral route (D) should only be considered if there are specific contraindications for the intravenous route. It's important to prioritize safe and effective medication administration based on the client's condition and healthcare provider's orders.

Correct Answer: C

Rationale: Correct Answer: C Rationale: 1. Choice C is correct because it emphasizes the importance of cleaning connections before accessing the device to prevent infection. 2. Sterile technique during insertion cannot guarantee no risk of infection (Choice B). 3. Wearing a sling is unnecessary for a central vascular access device (Choice A). 4. The statement about not being able to take a bath is not accurate and is not a common restriction (Choice D).
