Nursing Elites

1. 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.

2. What is the primary purpose of a platelet count?

• A. Assessing clot formation potential
• B. Assessing bleeding risk
• C. Detecting antigen-antibody response
• D. Identifying cardiac enzymes presence

Correct answer: B

Rationale: A platelet count is primarily used to assess the risk of bleeding. Platelets play a crucial role in blood clotting, so a low platelet count can lead to an increased risk of bleeding. Monitoring platelet levels helps healthcare providers evaluate a patient's ability to form clots and manage bleeding.

3. 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.

4. 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.

5. A client has had a cast applied, and a nurse is providing care. Which of the following actions should the nurse take first?

• A. Place an ice pack over the cast.
• B. Palpate the pulse distal to the cast.
• C. Teach the client to keep the cast clean and dry.
• D. Position the casted extremity on a pillow.

Correct answer: B

Rationale: When caring for a client with a newly applied cast, the nurse's priority should be to assess the circulation by palpating the pulse distal to the cast. This is crucial to ensure there is no compromise in blood flow, which could lead to serious complications. Placing an ice pack over the cast, teaching the client about cast care, and positioning the casted extremity on a pillow are important interventions but should follow the assessment of circulation.
