ATI Fundamentals

1. A healthcare professional is reviewing ABG laboratory results of a client who is in respiratory distress. The results are pH 7.47, PaCO2 32 mm Hg, and HCO3 22 mm Hg. The healthcare professional should recognize that the client is experiencing which of the following acid-base imbalances?

A. Respiratory acidosis
B. Respiratory alkalosis
C. Metabolic acidosis
D. Metabolic alkalosis

Correct answer: B

Rationale: The ABG results show a high pH (alkalosis) along with low PaCO2 and normal HCO3 levels, indicating respiratory alkalosis. In this condition, there is excessive loss of carbon dioxide (as seen by the low PaCO2) leading to a decrease in carbonic acid concentration and subsequent increase in pH. Metabolic acidosis or alkalosis would involve primary changes in bicarbonate levels, which are not predominant in this case.

2. All of the following interventions are correct when using the Z-track method of drug injection except:

A. Prepare the injection site with alcohol
B. Use a needle that is at least 1” long
C. Aspirate for blood before injection
D. Rub the site vigorously after the injection to promote absorption

Correct answer: D

Rationale: When using the Z-track method of drug injection, it is important to prepare the injection site with alcohol to ensure cleanliness, use a needle that is at least 1” long to reach the muscle tissue, and aspirate for blood before injection to verify correct needle placement. However, rubbing the site vigorously after the injection is not recommended as it can cause medication to leak into subcutaneous tissue, compromising the medication's intended absorption and efficacy.

3. A healthcare professional is reviewing laboratory data for a client who has chronic kidney disease. Which of the following findings should the healthcare professional expect?

A. Increased creatinine.
B. Increased hemoglobin.
C. Increased bicarbonate.
D. Increased calcium.

Correct answer: A

Rationale: In chronic kidney disease, the kidneys are unable to effectively filter waste products from the blood, leading to an accumulation of creatinine. Creatinine levels are commonly elevated in individuals with impaired kidney function, making it a key indicator of kidney health. Therefore, an increased creatinine level would be an expected finding in a client with chronic kidney disease.

4. What is the appropriate needle gauge for intradermal injection?

A. 20G
B. 22G
C. 25G
D. 26G

Correct answer: D

Rationale: Intradermal injections require a very fine needle to be used to deliver the medication into the dermis layer of the skin. A 26G needle is typically used for intradermal injections as it is thin enough to penetrate the skin's surface and deposit the medication accurately.

5. Which of the following techniques involves the sense of sight?

A. Inspection
B. Palpation
C. Percussion
D. Auscultation

Correct answer: A

Rationale: The correct answer is Inspection (Choice A). Inspection is a technique that involves observing the patient using the sense of sight. During inspection, a healthcare provider visually examines the patient for any abnormalities, changes, or specific signs that may help in diagnosing a condition. Palpation (Choice B) involves using the sense of touch to feel for abnormalities. Percussion (Choice C) involves tapping the body to produce sounds that can help identify the underlying structures. Auscultation (Choice D) involves listening to sounds produced by the body, typically using a stethoscope. Therefore, in this context, the technique that specifically involves the sense of sight is Inspection.
