Nursing Elites

1. A client is newly prescribed lithium for bipolar disorder. Which finding is most important to report to the healthcare provider?

• A. A serum lithium level of 1.2 mEq/L.
• B. Fine hand tremors noted after starting the medication.
• C. A blood pressure of 110/60 mmHg.
• D. A serum sodium level of 140 mEq/L.

Correct answer: B

Rationale: The correct answer is B. Fine hand tremors noted after starting lithium are an early sign of lithium toxicity. It is crucial to report this finding to the healthcare provider promptly. Adjusting the dose or monitoring serum levels more closely may be necessary to prevent further toxicity. Choice A, a serum lithium level of 1.2 mEq/L, is within the therapeutic range (0.6-1.2 mEq/L) for treating bipolar disorder. Choice C, a blood pressure of 110/60 mmHg, and Choice D, a serum sodium level of 140 mEq/L, are within normal limits and not directly related to lithium therapy or toxicity.

2. 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.

3. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is receiving oxygen therapy. Which assessment finding indicates that the client's oxygenation is improving?

• A. Pulse oximetry reading of 94%
• B. Heart rate increases from 80 to 90 beats per minute
• C. Respiratory rate increases from 16 to 20 breaths per minute
• D. Client reports increased energy levels

Correct answer: A

Rationale: A pulse oximetry reading of 94% indicates adequate oxygenation. Monitoring oxygen saturation is the most objective way to assess the effectiveness of oxygen therapy. Choices B, C, and D do not directly reflect the client's oxygenation status. An increase in heart rate or respiratory rate may indicate increased work of breathing or stress on the body. The client reporting increased energy levels is subjective and may not directly correlate with improved oxygenation.

4. When a client is suspected of having a stroke, what is the nurse's priority action?

• A. Administer tissue plasminogen activator (tPA).
• B. Perform a neurological assessment.
• C. Position the client in a supine position.
• D. Check the client's blood glucose level.

Correct answer: B

Rationale: The correct answer is to perform a neurological assessment. When a stroke is suspected, the priority action is to assess the client neurologically to determine the extent of brain injury and identify any immediate risks, such as impaired airway, speech deficits, or loss of motor function. This assessment helps in early recognition of signs that are essential for timely intervention and guides further treatment, such as administering tissue plasminogen activator (tPA), if appropriate. Positioning the client in a supine position or checking the blood glucose level can be important but not the priority when a stroke is suspected.

5. A client reports dizziness when standing up quickly. What advice should the nurse give?

• A. Encourage the client to drink more fluids.
• B. Change positions slowly to prevent dizziness.
• C. Report the symptom to the healthcare provider immediately.
• D. Limit physical activity to avoid triggering dizziness.

Correct answer: B

Rationale: The correct advice for a client experiencing dizziness when standing up quickly is to change positions slowly to prevent dizziness. This symptom is suggestive of postural hypotension, where a sudden change in position can lead to a drop in blood pressure, causing dizziness. Encouraging the client to drink more fluids (Choice A) may be beneficial for other conditions but is not directly related to the prevention of dizziness in this case. Reporting the symptom to the healthcare provider immediately (Choice C) is important if the dizziness is persistent or severe, but the immediate action to prevent it is to change positions slowly. Limiting physical activity (Choice D) may not necessarily address the underlying cause of dizziness in this context.
