1. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

A. Respiratory acidosis
B. Respiratory alkalosis
C. Increased PaCO2
D. CNS disturbances

Correct answer: B

Rationale:

2. 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:

3. What is the function of aldosterone?

A. Regulates body temperature.
B. Decreases blood pressure.
C. Increases sodium reabsorption.
D. Promotes water excretion.

Correct answer: C

Rationale: Aldosterone increases the reabsorption of sodium in the kidneys, which leads to an increase in blood volume and blood pressure. Choice A is incorrect as aldosterone does not regulate body temperature. Choice B is incorrect as aldosterone increases blood pressure by increasing sodium reabsorption. Choice D is incorrect as aldosterone promotes water retention by increasing sodium reabsorption.

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

A. Calcium levels
B. Phosphorus levels
C. Potassium levels
D. Magnesium levels

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.

5. Which of the following are sources of water intake?

A. Drinking fluids.
B. Consuming water from the food we eat.
C. Water from metabolic processes.
D. Drinking fluids, consuming water from the food we eat, and water from metabolic processes.

Correct answer: D

Rationale: The correct answer is D. The sources of water intake include drinking fluids, consuming water from the food we eat, and water from metabolic processes. Water intake is not solely from the liquids we drink but also from the water content present in the food we consume and the water produced during metabolic processes such as cellular respiration. Therefore, option D is the correct answer as it covers all the sources of water intake. Options A, B, and C alone do not encompass all the sources of water intake, making them incorrect choices.
