Nursing Elites

1. The nurse is assessing a client with a suspected pulmonary embolism (PE). Which symptom is most indicative of this condition?

• A. Bilateral leg swelling.
• B. Sudden onset of chest pain.
• C. Gradual onset of dyspnea.
• D. Decreased breath sounds on auscultation.

Correct answer: C

Rationale: The correct answer is C: 'Gradual onset of dyspnea.' While pulmonary embolism can present with various symptoms, the most common include sudden onset of dyspnea, chest pain (often pleuritic in nature), tachypnea, and tachycardia. Bilateral leg swelling is more commonly associated with conditions like deep vein thrombosis, not pulmonary embolism. Decreased breath sounds on auscultation may be seen in conditions like pneumothorax, not typically in pulmonary embolism. Therefore, the gradual onset of dyspnea is the most indicative symptom of pulmonary embolism in this scenario.

2. When using a metered-dose inhaler (MDI), which step is most important for ensuring effective medication delivery?

• A. Exhale completely before using the inhaler
• B. Inhale quickly while pressing down on the inhaler
• C. Shake the inhaler for 10 seconds before use
• D. Hold breath for 5 seconds after inhaling

Correct answer: A

Rationale: The correct step to ensure effective medication delivery when using a metered-dose inhaler (MDI) is to exhale completely before using the inhaler. This action helps create more space in the lungs for the medication to reach deeply into the airways. Inhaling quickly while pressing down on the inhaler (Choice B) may cause the medication to impact the throat rather than reaching the lungs. Shaking the inhaler for 10 seconds before use (Choice C) is important to mix the medication but not the most crucial step for effective delivery. While holding the breath for 5 seconds after inhaling (Choice D) can help the medication stay in the lungs momentarily, exhaling completely before inhalation is more critical for optimal drug deposition.

3. Which nursing activity is within the scope of practice for the practical nurse?

• A. Complete an admission assessment in the normal newborn nursery
• B. Discontinue a central venous catheter that has become dislodged
• C. Observe a client rotate the subcutaneous site for an insulin pump
• D. Monitor a continuous narcotic epidural for a postoperative client

Correct answer: C

Rationale: The correct answer is C: 'Observe a client rotate the subcutaneous site for an insulin pump.' This activity is within the scope of practice for a practical nurse as it involves observing and ensuring proper technique for using an insulin pump, which aligns with their training and responsibilities. Choices A, B, and D are beyond the typical scope of practice for a practical nurse. Completing an admission assessment for a newborn nursery is usually performed by a registered nurse. Discontinuing a dislodged central venous catheter and monitoring a narcotic epidural require advanced skills and knowledge, usually carried out by registered nurses or advanced practice nurses.

4. A client with a severe headache is being assessed by a nurse. What should the nurse do first?

• A. Administer pain relief medication
• B. Check the client's blood pressure
• C. Assess for associated symptoms such as nausea or photophobia
• D. Offer a quiet environment

Correct answer: B

Rationale: When a client presents with a severe headache, the initial action should be to check their blood pressure. This step is crucial as it can help determine if the headache is related to hypertension or other cardiovascular issues. Administering pain relief medication should only be done after assessing the client's vital signs and confirming the cause of the headache. While assessing for associated symptoms like nausea or photophobia is important for a comprehensive evaluation, it should follow checking the blood pressure to address immediate concerns. Offering a quiet environment is indeed beneficial for the client's comfort, but it is not the priority when dealing with a severe headache.

5. A client is prescribed metformin for the management of type 2 diabetes. What is the primary action of this medication?

• A. Stimulates insulin secretion from the pancreas.
• B. Increases insulin sensitivity in various tissues.
• C. Decreases hepatic glucose production.
• D. Delays absorption of glucose from the intestines.

Correct answer: C

Rationale: The correct answer is C: Decreases hepatic glucose production. Metformin primarily works by reducing the production of glucose in the liver (hepatic glucose production) and by improving insulin sensitivity in various tissues. Choice A is incorrect as metformin does not stimulate insulin secretion from the pancreas. Choice B is incorrect as metformin increases insulin sensitivity in various tissues, not just muscle cells. Choice D is incorrect as metformin does not delay glucose absorption from the intestines.
