Nursing Elites

1. What is the primary purpose of administering insulin to a patient with diabetes?

• A. Regulate blood glucose levels
• B. Increase metabolism
• C. Prevent complications
• D. Promote insulin sensitivity

Correct answer: A

Rationale: The correct answer is A: 'Regulate blood glucose levels.' Administering insulin to a patient with diabetes helps regulate blood glucose levels by facilitating the uptake of glucose into cells, thereby lowering high blood sugar levels. This process aims to prevent hyperglycemia and its associated complications. Choice B, 'Increase metabolism,' is incorrect as the primary role of insulin is not to increase metabolism directly. Choice C, 'Prevent complications,' is partially correct as regulating blood glucose through insulin administration does help prevent complications associated with uncontrolled diabetes, but it is not the primary purpose. Choice D, 'Promote insulin sensitivity,' is incorrect as insulin itself is administered to compensate for the lack of endogenous insulin in diabetic patients, rather than to promote sensitivity to it.

2. Which lab value should be monitored in patients receiving heparin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor aPTT in patients receiving heparin therapy. Activated Partial Thromboplastin Time (aPTT) is crucial to assess the therapeutic effectiveness of heparin and to prevent bleeding complications. Monitoring INR (Choice B) is more relevant for patients on warfarin therapy, not heparin. Platelet count (Choice C) monitoring is essential for detecting heparin-induced thrombocytopenia rather than assessing heparin therapy itself. Monitoring sodium levels (Choice D) is not directly related to heparin therapy monitoring.

3. A nurse is preparing to perform a sterile dressing change. Which of the following actions should the nurse take when setting up the sterile field?

• A. Place the cap from the solution sterile side up on a clean surface.
• B. Open the outermost flap of the sterile kit away from the body.
• C. Place the sterile dressing within 1.25 cm of the edge of the sterile field.
• D. Set up the sterile field 5 cm below waist level.

Correct answer: B

Rationale: When setting up a sterile field for a dressing change, the nurse should open the outermost flap of the sterile kit away from the body. This action helps maintain the sterility of the field by minimizing the risk of contamination. Option A is incorrect because the cap from the solution should be placed sterile side down to prevent contamination. Option C is incorrect because the sterile dressing should be placed at least 1.25 cm away from the edge of the sterile field to maintain its sterility. Option D is incorrect because the sterile field should be set up above waist level to prevent potential contamination from reaching the field.

4. What is the best intervention for a patient presenting with respiratory distress?

• A. Administer oxygen
• B. Administer bronchodilators
• C. Reposition the patient
• D. Provide humidified air

Correct answer: A

Rationale: Administering oxygen is the most critical intervention for a patient in respiratory distress as it helps improve oxygenation levels. Oxygen therapy aims to increase oxygen saturation in the blood, providing relief and support during episodes of respiratory distress. Administering bronchodilators may be beneficial in some cases, but oxygen therapy takes precedence in addressing the underlying issue of inadequate oxygenation. Repositioning the patient may help optimize ventilation but does not directly address the primary need for increased oxygen. Providing humidified air can offer comfort but does not address the urgent need for improved oxygen levels in a patient experiencing respiratory distress.

5. A client with gastroesophageal reflux disease (GERD) is being taught about lifestyle changes to manage the condition. Which of the following instructions should the nurse include?

• A. Avoid eating small, frequent meals.
• B. Sleep with the head of your bed elevated.
• C. Lie down after eating.
• D. Avoid drinking fluids with meals.

Correct answer: B

Rationale: The correct answer is B: 'Sleep with the head of your bed elevated.' Elevating the head of the bed helps reduce acid reflux by keeping the head higher than the stomach, preventing stomach acid from flowing back into the esophagus. Choices A, C, and D are incorrect. Avoiding eating small, frequent meals, lying down after eating, and drinking fluids with meals can exacerbate GERD symptoms by increasing stomach acid production and promoting acid reflux.
