Question 1 of 5
The kidneys regulate acid-base balance by all of the following mechanisms except:
Correct Answer: B
Rationale: Rationale: The correct answer is B because the kidneys do not reabsorb carbon dioxide to regulate acid-base balance. Carbon dioxide is mainly regulated by the lungs through respiration. The kidneys regulate acid-base balance by excreting hydrogen ions, reabsorbing or excreting bicarbonate (HCO3-) into the blood, and retaining or excreting hydrogen ions. Reabsorbing carbon dioxide is not a mechanism utilized by the kidneys for acid-base balance. Choices A, C, and D are correct mechanisms involved in acid-base balance regulation by the kidneys.
Question 2 of 5
Which of the ff values pertaining to different clients shows the normal range of plasma pH?
Correct Answer: A
Rationale: The correct answer is A: 7.35-7.45. Plasma pH typically falls within this range for normal clients. A pH of 7.35-7.45 indicates a slightly alkaline to neutral environment, which is essential for various physiological processes to function optimally. Choices B, C, and D have pH values outside the normal range, indicating either acidic (B and C) or highly alkaline (D) conditions, which would be abnormal and potentially harmful to the body's functioning. Therefore, the normal range for plasma pH is crucial to maintain homeostasis and support overall health.
Question 3 of 5
Which vein should be used first when initiating IV therapy?
Correct Answer: B
Rationale: The correct answer is B: Basilic vein. It is preferred for IV therapy due to its size, accessibility, and lower risk of complications. Basilic vein is deep and stable, aiding in successful catheter insertion and reduced risk of infiltration. Jugular vein (A) is not typically used due to the high risk of complications like infection. Brachiocephalic (C) and Axillary (D) veins are less commonly used as they are smaller and more prone to complications compared to the Basilic vein. In summary, the Basilic vein is the optimal choice for initiating IV therapy due to its size, accessibility, stability, and lower risk of complications.
Question 4 of 5
Why may an ice collar be ordered for a client who is undergoing drainage of a peritonsillar abscess?
Correct Answer: B
Rationale: The correct answer is B: To prevent respiratory obstruction. An ice collar is used to reduce swelling and inflammation, which can help prevent the abscess from compressing the airway and causing respiratory obstruction. This is crucial in cases of peritonsillar abscess to ensure the client's airway remains patent. Choices A, C, and D do not directly address the primary concern of preventing respiratory obstruction in this context.
Question 5 of 5
Which of the following would be the most appropriate nursing intervention when caring for a client with a fractured rib?
Correct Answer: A
Rationale: Correct Answer: A - Apply immobilization device after examination by physician Rationale: 1. Immobilization helps reduce pain and prevent further injury. 2. Physician examination ensures proper diagnosis and treatment plan. 3. Immobilization device may include chest binders or splints for support. 4. It is crucial to follow medical advice to prevent complications. Summary: B: Discouraging deep breaths can lead to respiratory complications. C: Advising against analgesics can increase pain and hinder recovery. D: Increased fluid intake is important but not directly related to rib fracture care.
