1. 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.

2. 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.

3. The physician orders the administration of high-humidity oxygen by face mask and placement of the patient in a high Fowler’s position. After assessing Mrs. Paul, the nurse writes the following nursing diagnosis: Impaired gas exchange related to increased secretions. Which of the following nursing interventions has the greatest potential for improving this situation?

• A. Encourage the patient to increase her fluid intake to 200 ml every 2 hours
• B. Place a humidifier in the patient’s room
• C. Continue administering oxygen by high humidity face mask
• D. Perform chest physiotherapy on a regular schedule

Correct answer: D

Rationale: Chest physiotherapy is the most effective intervention in cases of impaired gas exchange related to increased secretions. This technique helps mobilize and clear secretions from the airways, thereby improving gas exchange in the lungs. Placing a humidifier or administering oxygen by high humidity face mask may provide moisture but may not directly address the clearance of secretions. Encouraging increased fluid intake can help with hydration but may not address the underlying issue of impaired gas exchange due to secretions.

4. A patient with no known allergies is to receive penicillin every 6 hours. When administering the medication, the nurse observes a fine rash on the patient’s skin. The most appropriate nursing action would be to:

• A. Withhold the medication and notify the physician
• B. Administer the medication and notify the physician
• C. Administer the medication with an antihistamine
• D. Apply corn starch soaks to the rash

Correct answer: A

Rationale: In this scenario, the appearance of a rash after administering penicillin, even in a patient with no known allergies, is concerning for a potential allergic reaction. The appropriate action for the nurse to take is to withhold the medication and notify the physician. This precaution is necessary to prevent further administration of a medication that may be causing an adverse reaction, as allergic reactions can range from mild to severe and require immediate intervention.

5. The healthcare professional prepares to administer buccal medication. The medicine should be placed...

• A. On the client's skin
• B. Between the client's cheeks and gums
• C. Under the client's tongue
• D. On the client's conjunctiva

Correct answer: B

Rationale: Buccal medication is administered by placing it between the client's cheeks and gums. This route allows for the medication to be absorbed through the mucous membranes in the mouth, providing a rapid onset of action compared to oral ingestion. Placing the medication under the tongue (sublingual) allows for absorption through the sublingual mucosa, not the buccal mucosa. Placing medication on the skin or the conjunctiva is not appropriate for buccal administration.
