Nursing Elites

1. A healthcare provider is reviewing laboratory results for a client who has diabetes mellitus. Which of the following tests is an indicator of long-term blood glucose control?

• A. Fasting blood glucose
• B. Glycosylated hemoglobin (HbA1c)
• C. Random blood glucose
• D. Postprandial blood glucose

Correct answer: B

Rationale: The correct answer is B, Glycosylated hemoglobin (HbA1c). HbA1c provides a measure of long-term blood glucose control over the past 2-3 months. This test reflects the average blood glucose levels during this period, making it a valuable tool in managing diabetes. Choices A, C, and D are not indicators of long-term blood glucose control. Fasting blood glucose measures the current glucose level after a period of not eating, random blood glucose provides a snapshot of the current glucose level, and postprandial blood glucose measures the glucose level after a meal.

2. A nurse is preparing to administer heparin subcutaneously to a client. Which of the following actions should the nurse take?

• A. Use a 21-gauge needle for injection.
• B. Inject the medication into the client's deltoid muscle.
• C. Administer the medication within 5 cm (2 in) of the umbilicus.
• D. Massage the injection site after administration.

Correct answer: C

Rationale: The correct action the nurse should take when preparing to administer heparin subcutaneously is to administer the medication within 5 cm (2 in) of the umbilicus. This practice ensures proper subcutaneous delivery of the medication. Choice A is incorrect because a smaller gauge needle, typically 25-26 gauge, is used for subcutaneous injections. Choice B is incorrect as heparin should not be injected into the deltoid muscle but rather into fatty tissue. Choice D is incorrect as massaging the injection site after administration can lead to tissue irritation or bruising.

3. What is the initial action for a healthcare provider when a patient presents with shortness of breath?

• A. Administer oxygen
• B. Reposition the patient
• C. Check for abnormal breath sounds
• D. Check oxygen saturation

Correct answer: A

Rationale: Administering oxygen is the initial action for a healthcare provider when a patient presents with shortness of breath because it helps alleviate the patient's symptoms by improving oxygenation. Providing oxygen takes precedence over other actions such as repositioning the patient, checking for abnormal breath sounds, or assessing oxygen saturation. While these actions are important, ensuring the patient has an adequate oxygen supply is crucial in the initial management of shortness of breath.

4. A nurse is caring for a client who has a tracheostomy. Which of the following actions should the nurse take when providing tracheostomy care?

• A. Use sterile technique when performing tracheostomy care.
• B. Replace the tracheostomy ties every 24 hours.
• C. Use a sterile brush to clean the inner cannula.
• D. Change the tracheostomy dressing once a week.

Correct answer: C

Rationale: The correct answer is to use a sterile brush to clean the inner cannula. This action is crucial to prevent infection during tracheostomy care. Choice A is incorrect as clean technique is not adequate for tracheostomy care, sterile technique is required. Choice B is incorrect as tracheostomy ties should be replaced when soiled, not routinely every 24 hours. Choice D is incorrect as tracheostomy dressings should be changed more frequently to maintain cleanliness and prevent infection.

5. Which lab value should be monitored for a patient on warfarin therapy?

• A. Monitor INR
• B. Monitor potassium levels
• C. Monitor platelet count
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor INR for a patient on warfarin therapy. INR monitoring is crucial as it helps assess the therapeutic effectiveness and safety of warfarin. INR stands for International Normalized Ratio, and it measures the blood's ability to clot. Monitoring potassium levels (Choice B) is not specific to warfarin therapy. Monitoring platelet count (Choice C) is important but not the primary lab value for assessing warfarin therapy. Monitoring sodium levels (Choice D) is not directly related to warfarin therapy.
