1. What electrolyte value should be monitored when a patient is receiving a loop diuretic?

Correct answer: C

Rationale: When a patient is receiving a loop diuretic like furosemide (Lasix), potassium levels should be monitored closely. Loop diuretics act on the ascending loop of Henle to inhibit the reabsorption of sodium and water, leading to potassium loss. Monitoring potassium levels is crucial to prevent hypokalemia, which can result in serious complications such as cardiac arrhythmias. Calcium levels (Choice A), phosphorus levels (Choice B), and magnesium levels (Choice D) are not typically affected directly by loop diuretics and do not require routine monitoring in this context.

2. Which negative ion is most important in intracellular fluid?

Correct answer: D

Rationale: Intracellular fluid contains phosphate ions and protein molecules as essential anions. Phosphate ions play a crucial role in various cellular processes, including energy transfer. Proteins, being large molecules with negative charges, also contribute significantly to the negative ion concentration within cells. Chlorine is primarily an extracellular anion and is not as prominent as phosphate ions and proteins within intracellular fluid, making it a less important negative ion in this context. Therefore, the correct answer is D because both phosphate ions and protein molecules are crucial negative ions in intracellular fluid.

3. How would a decrease in blood protein concentration impact the fluid volumes?

Correct answer: D

Rationale: A decrease in blood protein concentration would lead to a reduction in osmotic pressure, which is responsible for drawing fluid back into the capillaries. This decrease in osmotic pressure would result in an increase in interstitial fluid volume as fluid moves out of the capillaries, and a decrease in blood plasma volume as less fluid is drawn back into the circulation. Therefore, the correct answer is to increase interstitial fluid volume and decrease blood plasma volume. Choices A, B, and C are incorrect because they do not reflect the impact of decreased blood protein concentration on fluid volumes.

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?

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. A nurse assesses a client who is prescribed a medication that inhibits aldosterone secretion and release. For which potential complications should the nurse assess? (Select all that apply.)

Correct answer: A
