An ABG reveals the following results: pH 7.28, PaCO2 50 mm Hg, HCO3 23 mEq/L. The nurse should recognize the likelihood of what acidbase disorder?

• A. Respiratory acidosis
• B. Metabolic alkalosis
• C. Respiratory alkalosis
• D. Mixed acidbase disorder

Correct answer: D

Rationale:

2. A home care nurse prepares to administer intravenous medication to a client. The nurse assesses the site and reviews the clients chart prior to administering the medication: Client: Thomas Jackson DOB: 5/3/1936 Gender: Male January 23 (Today): Right uppe

4. You are working on a burns unit, and one of your acutely ill patients is exhibiting signs and symptoms of third spacing. Based on this change in status, you should expect the patient to exhibit signs and symptoms of what imbalance?

• A. Metabolic alkalosis
• B. Hypermagnesemia
• C. Hypercalcemia
• D. Hypovolemia

Correct answer: D

Rationale: Third spacing refers to the loss of fluid from the intravascular space into the interstitial or third space, leading to a decrease in circulating blood volume. This condition results in hypovolemia, which is characterized by decreased blood volume. Metabolic alkalosis, hypermagnesemia, and hypercalcemia are not directly associated with third spacing. Metabolic alkalosis is an acid-base imbalance, hypermagnesemia is an excess of magnesium in the blood, and hypercalcemia is an excess of calcium in the blood, none of which are the primary concerns in cases of third spacing.

5. What is the most important regulator of the amount of sodium in the body?

• A. Kidneys
• B. Small intestine
• C. Large intestine
• D. Skin

Correct answer: A

Rationale: The correct answer is A: Kidneys. The kidneys play a crucial role in regulating the amount of sodium in the body. They achieve this by filtering blood and controlling the excretion or reabsorption of sodium. The small intestine is primarily responsible for nutrient absorption, not sodium regulation. The large intestine is mainly involved in water absorption and waste elimination, not sodium balance. The skin helps regulate body temperature through sweating and does not directly regulate sodium levels.
