Nursing Elites

1. The home health nurse provides teaching about insulin self-injection to a client who was recently diagnosed with diabetes mellitus. When the client begins to perform a return demonstration of an insulin injection into the abdomen, which instruction should the nurse provide?

• A. Select a different injection site
• B. Continue with the insulin injection
• C. Keep the skin flat rather than bunched
• D. Lie down flat for better skin exposure

Correct answer: B

Rationale: Choosing to continue with the insulin injection is the correct instruction in this scenario because it allows the client to demonstrate proper technique and reinforces their learning. Selecting a different injection site (choice A) is not necessary if the client is injecting into the abdomen as it is a suitable site. Keeping the skin flat rather than bunched (choice C) is a good practice but is not the priority in this situation where the client is demonstrating the injection technique. Lying down flat for better skin exposure (choice D) is not required and may not be practical for the client during routine self-injections.

2. A CD4+ lymphocyte count is performed on a client infected with HIV. The results of the test indicate a CD4+ count of 450 cells/L. The nurse interprets this test result as indicating:

• A. Improvement in the client
• B. The need for antiretroviral therapy
• C. The need to discontinue antiretroviral therapy
• D. An effective response to the treatment for HIV

Correct answer: B

Rationale: A CD4+ count of 450 cells/L is below the normal range (500-1600 cells/mcL), indicating a decline in immune function in the client. Antiretroviral therapy is recommended when the CD4+ count falls below 500 cells/mcL or below 25%, or when the client displays symptoms of HIV. Therefore, the interpretation of this test result suggests that the client requires antiretroviral therapy to manage the HIV infection. Choices A, C, and D are incorrect because a CD4+ count of 450 cells/L does not signify improvement, discontinuation of therapy, or an effective response to treatment for HIV.

3. Upon arrival of a client transferred to the surgical unit, what should the nurse plan to do first?

• A. Assess the patency of the airway
• B. Check tubes and drains for patency
• C. Check the dressing for bleeding
• D. Assess the vital signs to compare them with preoperative measurements

Correct answer: A

Rationale: The initial action for the nurse upon the arrival of a client to the surgical unit is to assess the patency of the airway. This step takes priority to ensure that the client has a clear airway for adequate breathing. Checking tubes and drains for patency, inspecting the dressing for bleeding, and assessing vital signs to compare with preoperative measurements are important subsequent steps in the assessment process. However, ensuring the airway is patent is the immediate priority to maintain the client's respiratory function and overall well-being.

4. The nurse is preparing to administer an antibiotic to a patient who has been receiving the antibiotic for 2 days after a culture was obtained. The nurse notes increased erythema and swelling, and the patient has a persistent high fever of 39°C. What is the nurse’s next action?

• A. Administer the antibiotic as ordered.
• B. Contact the provider to request another culture.
• C. Discuss the need to add a second antibiotic with the provider.
• D. Review the sensitivity results from the patient’s culture.

Correct answer: D

Rationale: In this scenario, the nurse is observing signs of a possible lack of response to the current antibiotic therapy, such as increased erythema, swelling, and persistent high fever. The next appropriate action for the nurse is to review the sensitivity results from the patient’s culture. This step is crucial to determine if the current antibiotic is effective against the causative organism. If the sensitivity results indicate resistance to the current antibiotic, the antibiotic should be discontinued, and the provider should be notified for a change in therapy. Contacting the provider to request another culture is not the immediate priority, as the existing culture results need to be reviewed first. Adding a second antibiotic should only be considered after confirming the sensitivity results, as unnecessary antibiotic use can lead to antimicrobial resistance.

5. A healthcare professional reviews the blood gas results of a client in respiratory distress. The pH is 7.32, and the PCO2 is 50 mm Hg. Which of the following acid-base imbalances does the professional recognize in these findings?

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

Correct answer: C

Rationale: In respiratory acidosis, the pH is low (<7.35) and the PCO2 is increased (>45 mm Hg). These findings indicate that the client is experiencing respiratory acidosis, a condition where there is an excess of carbon dioxide in the blood due to inadequate ventilation, commonly seen in respiratory distress. Metabolic acidosis (Choice A) is characterized by a low pH and decreased bicarbonate levels, which is not the case in this scenario. Metabolic alkalosis (Choice B) is associated with a high pH and increased bicarbonate levels. Respiratory alkalosis (Choice D) is marked by a high pH and decreased PCO2, opposite to the values presented in the blood gas results of this client.
