Acid-base Questions And Answers Pdf

[Geraldine Ferraiz]

Inthis section are the practice problems and questions for arterial blood gas interpretation. This nursing test bank set includes 40 questions divided into two parts. Includes topics are arterial blood gas interpretation, acid-base balance and imbalances, respiratory acidosis and alkalosis, and metabolic acidosis and alkalosis.

Based on the given ABG values, pH is 7.39. For pH, the normal range is 7.35 to 7.45. So it is NORMAL.

PaCO2 is 59. The normal range for PaCO2 is from 35 to 45. If PaCO2 is above 45, it is acidosis. Based on the given ABG values, PaCO2 is above 45, so it is considered ACIDOSIS.

HCO3- is 35. The normal range for HCO3 is from 22 to 26. If HCO3 is above 26, it is alkalosis. Based on the given ABG values, HCO3 is above 26, so it is considered ALKALOSIS.

For these ABG values, pH is NORMAL but slightly acidic and lines up with PACO2 which is METABOLIC. Therefore, this group of ABG values is considered METABOLIC ALKALOSIS.

Lastly, it is FULLY COMPENSATED because pH is normal. It is considered fully compensated if pH is normal.

I beg to disagree with your analysis.

The answer is correct Respiratory Acidosis with Fully compensated. The pH is within normal limits, the PCO2 is high meaning respiratory aspect is getting acidotic and because the respiratory is getting acidotic the kidney which the HCO3 is compensating well by increasing.

I respectfully disagree with your analysis of the question as well. Since the pH is within normal limits, it is fully compensated, you are correct. The absolute normal for pH is 7.4, so since 7.39 is below the absolute it is still considered acidic. From there, The PaCO2 is elevated above normal range of 35-45, along with HCO3- elevated from the normal range of 22-26. HCO3- is elevated due to renal compensation. We know with respiratory disorders of ABGs, respiratory values go in opposite directions of one another and metabolic values go in the same directions (ROME method). Therefore, this situation is respiratory acidosis.

You are correct Thompson, that there is compensation. This is because the bicarb has increased, providing a normal ph. A client with a PaCO2 of 59 is still having respiratory issues despite the body compensating. In response to Aliyah, Increased respirations are an attempt to get rid of more CO2.

A 73year man has been admitted to the unit with a diagnosis of chronic obstructive pulmonary disease .he states that he has difficulty breathing when walking short distance .he also states that his heart feels like it is racing at the same time .he states that he is tired all the time and while talking to you he is continually wringing his hands and looking out the windows.1.Identify the 4 health problem of the patient.2.formulate the nursing diagnosis

Thompson,

The PaCo2 is high and the pH is normal but slightly acidic because it is on the lower end. Using the ROME method, this would make it respiratory acidosis, fully compensated. I recommend using the ROME method (respiratory opposite metabolic equal).

In the Arterial Blood Gas Interpretation Practice Quiz (Part 1: 20 Items), I think the correct answer to Q3. should have been : Respiratory Alkalosis, Partially Compensated. Please revisit and let me know. Thanks for the resources.

The blood Ph is more towards Acidic. the PaCo2 is elevated, which is always an indicator for respiratory acidosis.

the HCO3 is also elevated, but an elevated HCO3 is is also always an indicator for Metabolic Alkalosis.

Since the Ph of the blood is is towards acidity, and the PaCO2 is elevated, the patient is in respiratory acidosis, the HCO3 is also elevated because homeostasis have set in an the body needs to form more alkaines to compensate for the increased acidity. since the Ph of the blood, though towards acidity but still within normal, that means the RESPIRATORY ACIDOSIS IS FULLY COMPENSATED.

The answer is Respiratory Acidosis, Fully compensated. This is because the ph is within normal range and based on the principle of ROME which is Respiratory Opposite Metabolic Equal, the PCO2 of 59 is Acidotic. Therefore, the PCO2 is Opposite to the ph (7.39) meaning that the result is Respiratory Acidosis, Fully compensated.

Known about blood gases in 1974 as a Navy Corpsman and now an RN, this tic tac toe made it as simple as ever, and it is free. Awesome lesson! A+!

While reading, I thought that the Allen test, which is needed to show blood flow to the hand, would be intact if the radial artery was damaged while drawing arterial blood, thus dependent on the ulnar artery. Seen myriads of ABGs but do not recall an Allen test ever being done. This lesson was EXCELLENT, systematic, step by step.

1. You are given three test tubes. The three test tubes contain distilled water, an acidic solution and the basic solution, respectively. There is only red litmus paper available in order to identify what is there in each test tube. How will you find out what is in each of the test tubes?

NOTE: After immediate distillation, distilled water has a pH of 7. However, within a few hours after distillation, it absorbs carbon dioxide from the atmosphere and turns slightly acidic with a pH of 5.8.

3. Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride.

Solution: As the metal compound released is Calcium Chloride, the gas evolved here is CO2. Hence, metal A should be Calcium Carbonate. Hence, the reaction between Calcium Carbonate and HCl is

Solution: Release of H+ ion in water will make a compound acidic or non-acidic. Acids are substances which, upon dissociating with water, resulting in the production of Hydrogen ions. Some compounds show an acidic character as they dissociate in the aqueous solution, which results in the production of hydrogen ions (acids like HCl, HNO3).

Compounds similar to glucose or alcohol do contain a hydrogen element, but they do not show signs of acidic nature. The fact is that the hydrogen in them will not separate from like the hydrogen in the acids. They will not separate to become hydrogen ions, on dissolving in the water.

Solution: Charged particles are responsible for the conductance of electricity in an acid. These charged particles, called ions, are the reason behind the conductance of electricity in acid.

Solution: While diluting an acid, it is recommended that the acid should be added to water and not water to the acid because if water is added to a concentrated acid, it releases a huge amount of heat which may result in an explosion and can cause acid burns on the face, clothes and body parts. Hence, it is safe to add acid to water but not water to acid.

Solution: When acid is added to water, there will be a fixed amount of hydronium present in the fixed volume of the solution. If we dilute the solution, hydronium ions per volume of the solution decrease, and this, in turn, decreases Hydronium concentration in the solution.

Solution: When a base is dissolved in sodium hydroxide solution, its hydroxide ions increase, but it will reach saturation at some point. After saturation point, hydroxide ion concentration is not affected even after adding base further.

1. You have two solutions, A and B. The pH of solution A is 6, and the pH of solution B is 8. Which solution has more hydrogen ion concentration? Which of these is acidic, and which one is basic?

Solution: Hydrogen ion concentration decides the nature of the solution. If Hydrogen ion concentration increase, then the solution turns acidic and similarly, if Hydrogen ion concentration decreases, then the solution turns basic.

4. Under what soil condition do you think a farmer would treat the soil of his fields with quick lime (calcium oxide) or slaked lime (calcium hydroxide), or chalk (calcium carbonate)?

3. 10 mL of a solution of NaOH is found to be completely neutralised by 8 mL of a given solution of HCl. If we take 20 mL of the same solution of NaOH, the amount of HCl solution (the same solution as before) required to neutralise it will be

Solution: Insert two nails into the wooden or rubber cork and place them on a beaker, as shown in the figure. Connect the iron nail to a bulb, a 6-volt battery and a wire connected to the switch. Pour some alcohol or glucose so as to dip the nails in glucose or alcohol. Turn the switch on, and you see the bulb not glowing despite of connection to the switch. Now empty the beaker and add the HCL solution. This time, the bulb glows. This proves acid can conduct electricity, but alcohol and glucose do not conduct electricity.

Solution: The acidic behaviour of acids is because of the presence of hydrogen ions. Hydrogen ions can only be produced in the presence of water, and therefore, water is definitely needed if acids are to show their acidic behaviour.
