. A medical nurse educator is reviewing a patients recent episode of metabolic acidosis with members of the nursing staff. What should the educator describe about the role of the kidneys in metabolic acidosis?

A. The kidneys retain hydrogen ions and excrete bicarbonate ions to help restore balance. B. The kidneys excrete hydrogen ions and conserve bicarbonate ions to help restore balance C. The kidneys react rapidly to compensate for imbalances in the body D. The kidneys regulate the bicarbonate level in the intracellular fluid.

Correct Answer: B

Rationale: Correct Answer: B - The kidneys excrete hydrogen ions and conserve bicarbonate ions to help restore balance. Rationale: 1. In metabolic acidosis, the blood pH is low due to excess acid in the body. 2. To restore pH balance, the kidneys excrete hydrogen ions (acid) and conserve bicarbonate ions (a base). 3. By excreting acid and retaining base, the kidneys help neutralize the excess acid in the body. 4. Option B accurately describes the role of the kidneys in metabolic acidosis. Incorrect Choices: A: Incorrect. The kidneys do not retain hydrogen ions in metabolic acidosis; they excrete them. C: Incorrect. While the kidneys do play a role in correcting imbalances, they do not react rapidly in metabolic acidosis. D: Incorrect. The kidneys do regulate bicarbonate levels, but this is not the primary action in metabolic acidosis.

Question 2 of 5

While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?

A. Grade 3 phlebitis at IV site B. infection at IV site C. Thrombosed area at IV site D. infiltration at IV site

Correct Answer: A

Rationale: The correct answer is A: Grade 3 phlebitis at IV site. This finding indicates inflammation of the vein due to irritants from the IV catheter, supported by red streak and palpable cord. Grade 3 phlebitis involves pain, redness, swelling, and palpable venous cord. Infection (B) typically presents with signs like pus, warmth, and fever. Thrombosis (C) involves a blood clot, not a palpable cord. Infiltration (D) is leakage of IV fluid into surrounding tissues, not related to palpable cord and red streak.

Question 3 of 5

Place a washcloth between the skin and tourniquet

A. Provide a bed bath instead of letting the client take a shower B. Use sterile technique when changing the dressing. C. Disconnect the intravenous fluid tubing prior to the clients bath. D. Use a plastic bag to cover the extremity with the device

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.

Question 4 of 5

A patient's most recent laboratory results show a slight decrease in potassium. The physician has opted to forego drug therapy but has suggested increasing the patient's dietary intake of potassium. Which of the following would be a good source of potassium?

A. Apples B. Asparagus C. Carrots D. Bananas

Correct Answer: D

Rationale: The correct answer is D: Bananas. Bananas are a good source of potassium, with around 400-500 mg per banana. Potassium is essential for maintaining proper muscle function, nerve signaling, and fluid balance in the body. Increasing dietary intake of potassium can help address a slight decrease in potassium levels without the need for drug therapy. Apples, asparagus, and carrots are not as high in potassium as bananas, making them less effective choices for addressing a potassium deficiency.

Question 5 of 5

A nurse is caring for a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. After removing the device, which action should the nurse take to relieve pain?

A. Administer topical lidocaine to the site. B. Place warm compresses on the site. C. . Administer prescribed oral pain medication. D. Massage the site with scented oils.

Correct Answer: B

Rationale: The correct answer is B: Place warm compresses on the site. Warm compresses can help increase blood flow, reduce pain, and promote healing at the site of inflammation. The warmth can help dilate blood vessels, increasing circulation to the area and promoting the removal of inflammatory substances. This can help alleviate pain and reduce swelling. Administering topical lidocaine (choice A) may not address the underlying cause of pain and redness. Administering oral pain medication (choice C) may be necessary for severe pain but may not directly address the local inflammation. Massaging the site with scented oils (choice D) can potentially introduce more irritants and should be avoided in cases of inflammation.
