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. The healthcare provider orders an IV solution of dextrose 5% in water at 100ml/hour. What would the flow rate be if the drop factor is 15 gtt = 1 ml?

• A. 5 gtt/minute
• B. 13 gtt/minute
• C. 25 gtt/minute
• D. 50 gtt/minute

Correct answer: C

Rationale: To determine the flow rate in drops per minute, multiply the ordered volume per hour by the drop factor (100 ml/hour x 15 gtt/ml = 1500 gtt/hour). Then, divide the result by 60 minutes to convert it to drops per minute (1500 gtt/hour ÷ 60 minutes = 25 gtt/minute). Therefore, the correct answer is 25 gtt/minute.

3. What is the term for the body's ability to defend itself against specific invading agents such as bacteria, toxins, viruses, and foreign bodies?

• A. Hormones
• B. Secretion
• C. Immunity
• D. Glands

Correct answer: C

Rationale: The correct answer is C: Immunity. Immunity refers to the body's ability to protect itself against specific invading agents like bacteria, toxins, viruses, and foreign bodies by recognizing and destroying them. It is a crucial defense mechanism that helps maintain health and prevent infections and diseases. Choices A, B, and D are incorrect because hormones are chemical messengers, secretion is the process of releasing substances, and glands are organs that produce and release substances, none of which specifically relate to the body's defense against invading agents.

4. What is required for effective hand washing?

• A. Soap or detergent to promote emulsification
• B. Hot water to destroy bacteria
• C. A disinfectant to increase surface tension
• D. All of the above

Correct answer: A

Rationale: To effectively wash hands, soap or detergent is essential as they help emulsify fats and oils, allowing them to be rinsed away. Hot water alone cannot effectively destroy bacteria, and a disinfectant is not typically required for routine hand washing.

5. The correct method for determining the vastus lateralis site for I.M. injection is to:

• A. Locate the upper aspect of the upper outer quadrant of the buttock about 5 to 8 cm below the iliac crest
• B. Palpate the lower edge of the acromion process and the midpoint lateral aspect of the arm
• C. Palpate a 1” circular area anterior to the umbilicus
• D. Divide the area between the greater femoral trochanter and the lateral femoral condyle into thirds, and select the middle third on the anterior of the thigh

Correct answer: D

Rationale: The vastus lateralis site is located in the middle third of the thigh.
