Nursing Elites

1. What pathophysiological events occur sequentially in the development of atherosclerosis?

• A. Foam cells release growth factors.
• B. Smooth muscle grows over fatty streaks creating fibrous plaques.
• C. Macrophages consume low-density lipoprotein (LDL) and create foam cells.
• D. Arterial endothelium injury causes inflammation.

Correct answer: D

Rationale: The correct sequence of pathophysiological events in the development of atherosclerosis starts with arterial endothelium injury causing inflammation. This inflammation triggers the formation of foam cells by macrophages consuming low-density lipoprotein (LDL). Subsequently, smooth muscle grows over fatty streaks, creating fibrous plaques. Therefore, option D is the correct answer. Choices A, B, and C are incorrect because they do not reflect the accurate chronological order of events in the pathogenesis of atherosclerosis.

2. A client receiving IV heparin reports abdominal pain and tarry stools. What is the nurse's priority action?

• A. Prepare to administer protamine sulfate.
• B. Continue the heparin infusion and notify the healthcare provider.
• C. Monitor the client's vital signs and assess abdominal pain.
• D. Administer a PRN dose of morphine sulfate.

Correct answer: A

Rationale: The correct answer is to prepare to administer protamine sulfate. Abdominal pain and tarry stools are indicative of gastrointestinal bleeding, a serious side effect of heparin therapy. Protamine sulfate is the antidote for heparin and is used to reverse its effects in cases of bleeding. Continuing the heparin infusion (Choice B) is not appropriate when the client is experiencing signs of bleeding. Monitoring vital signs and assessing abdominal pain (Choice C) is important but not the priority when immediate action is required to address potential bleeding. Administering morphine sulfate (Choice D) is not the priority in this situation; addressing the underlying cause of bleeding takes precedence.

3. A nurse finds a pregnant client at 33 weeks gestation in cardiac arrest. What modification to cardiopulmonary resuscitation (CPR) should the nurse implement?

• A. Administer chest compressions at a faster rate.
• B. Position a firm wedge under the client’s pelvis and thorax at a 30-degree tilt.
• C. Position the client flat with legs elevated.
• D. Call for immediate assistance and prepare for a cesarean section.

Correct answer: B

Rationale: In a pregnant client at 33 weeks gestation, performing CPR requires tilting the pelvis and thorax at a 30-degree angle to relieve pressure on the vena cava, ensuring proper circulation during compressions. Administering chest compressions at a faster rate (Choice A) may not address the specific needs of a pregnant client in cardiac arrest. Positioning the client flat with legs elevated (Choice C) is not recommended as it can worsen vena cava compression. Calling for immediate assistance and preparing for a cesarean section (Choice D) should be considered only after initiating appropriate CPR modifications.

4. An antibiotic IM injection for a 2-year-old child is ordered. The total volume of the injection equals 2.0 ml. The correct action is to

• A. Administer the medication in 2 separate injections
• B. Give the medication in the dorsal gluteal site
• C. Call to get a smaller volume ordered
• D. Check with the pharmacy for a liquid form of the medication

Correct answer: A

Rationale: Injections over 1 mL should be split into two separate injections for young children. This helps in preventing discomfort, ensuring proper absorption, and reducing the risk of tissue damage. Giving the medication in one injection of 2.0 ml might be too much for a 2-year-old child. Choices B and D are incorrect because the dorsal gluteal site is not recommended for children due to potential injury, and changing the form of medication might not be necessary if the volume can be adjusted. Choice C is unnecessary as splitting the dose into two injections is the appropriate action.

5. A client is experiencing angina at rest. Which statement indicates a good understanding of the care required?

• A. I will notify the nurse if my chest pain is not relieved in 30 minutes.
• B. I will use nitroglycerin as needed, every 5 minutes, up to 3 doses.
• C. I will avoid physical activity until the pain subsides completely.
• D. I will take nitroglycerin 30 minutes before any physical activity.

Correct answer: B

Rationale: The correct answer is B. Using nitroglycerin as needed, every 5 minutes, up to 3 doses, is the appropriate management for angina at rest. This helps dilate blood vessels, improving blood flow to the heart. Choice A is incorrect because chest pain that persists at rest should be addressed immediately, not waiting for 30 minutes. Choice C is incorrect as avoiding physical activity is not a recommended approach during an angina episode. Choice D is incorrect because nitroglycerin should be used during chest pain episodes, not as a preventive measure before physical activity.
