Nursing Elites

1. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.

2. A client with a diagnosis of chronic obstructive pulmonary disease (COPD) is receiving home oxygen therapy. What is the most important instruction the nurse should provide?

• A. Use oxygen at the highest flow rate tolerated.
• B. Do not smoke while using oxygen.
• C. Avoid wearing the oxygen during physical activity.
• D. Store oxygen tanks in a cool, dark place.

Correct answer: B

Rationale: The most important instruction the nurse should provide to a client with COPD receiving home oxygen therapy is not to smoke while using oxygen. Smoking near oxygen can cause a fire or explosion due to the flammable nature of oxygen. Choice A is incorrect because using oxygen at the highest flow rate tolerated without medical supervision can be harmful. Choice C is the correct answer as wearing oxygen during physical activity can increase the risk of oxygen combustion. Choice D is not the most important instruction; while storing oxygen tanks properly is essential, the immediate safety concern is the risk of fire due to smoking near oxygen.

3. A client reports feeling dizzy and light-headed when standing up. What is the nurse's best initial action?

• A. Instruct the client to sit or lie down
• B. Monitor blood pressure and pulse
• C. Administer an anti-dizziness medication
• D. Increase fluid intake

Correct answer: B

Rationale: The correct answer is B: Monitor blood pressure and pulse. When a client reports feeling dizzy and light-headed when standing up, the nurse's best initial action should be to monitor the client's blood pressure and pulse. These symptoms are indicative of orthostatic hypotension, which can be confirmed by changes in blood pressure and pulse when moving from lying to standing positions. Instructing the client to sit or lie down may provide temporary relief but does not address the underlying cause. Administering an anti-dizziness medication should not be the initial action without assessing vital signs first. Increasing fluid intake is important for overall health but is not the priority in this situation where vital sign monitoring is needed to assess for orthostatic hypotension.

4. The nurse observes a client with new-onset tachycardia. What should the nurse do first?

• A. Check for the client's temperature
• B. Administer prescribed beta-blockers
• C. Assess for any chest pain or discomfort
• D. Monitor the client's blood pressure

Correct answer: C

Rationale: When a client presents with new-onset tachycardia, the first action the nurse should take is to assess for any associated symptoms like chest pain or discomfort. This is important to differentiate the potential causes of tachycardia and guide appropriate interventions. Checking the client's temperature (Choice A) may be relevant in certain situations but is not the priority when tachycardia is observed. Administering prescribed beta-blockers (Choice B) should only be done after a comprehensive assessment and healthcare provider's orders. Monitoring the client's blood pressure (Choice D) is important, but assessing for chest pain or discomfort takes precedence in this scenario to rule out cardiac causes of tachycardia.

5. The nurse is monitoring a client with an IV infusion in the left antecubital fossa. The site is warm, red, and without swelling. What conclusion should the nurse draw from these findings?

• A. The IV fluids are infusing into the subcutaneous tissues
• B. The infusion pump is functioning properly
• C. The insertion date should be verified and the IV discontinued
• D. The site is inflamed and should be reported

Correct answer: B

Rationale: The correct answer is B. Warmth and redness at the IV site without swelling indicate a localized reaction, which is common and does not necessarily indicate infiltration of IV fluids into the subcutaneous tissues. The absence of swelling suggests that the IV is correctly placed. Therefore, the nurse should conclude that the infusion pump is functioning properly. Choice A is incorrect as warmth and redness alone do not indicate subcutaneous infiltration. Choice C is incorrect as discontinuing the IV solely based on warmth and redness without swelling is not necessary. Choice D is incorrect as the absence of swelling signifies a localized reaction rather than inflammation requiring immediate reporting.
