Nursing Elites

1. 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.

2. 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.

3. During an initial assessment, a healthcare provider notes that a client has elevated blood pressure. Which of the following findings is considered a major risk factor for coronary artery disease?

• A. Elevated HDL cholesterol
• B. Low LDL cholesterol
• C. Elevated blood pressure
• D. Low triglyceride levels

Correct answer: C

Rationale: Elevated blood pressure is a significant risk factor for coronary artery disease because it increases the strain on the arteries, leading to potential damage and a higher risk of developing coronary artery disease. Elevated HDL cholesterol (Choice A) is actually considered beneficial as it helps reduce the risk of heart disease. Low LDL cholesterol (Choice B) is also beneficial as high levels of LDL are associated with an increased risk of coronary artery disease. Low triglyceride levels (Choice D) are not typically considered a major risk factor for coronary artery disease.

4. The nurse is conducting intake interviews of children at a city clinic. Which child is most susceptible to contracting lead poisoning?

• A. An 8-year-old living in a housing project.
• B. A 2-year-old playing on aging playground equipment.
• C. An adolescent working in a paint factory.
• D. A 10-year-old with Type 1 diabetes.

Correct answer: B

Rationale: The correct answer is B. Young children, like the 2-year-old playing on aging playground equipment, are more susceptible to lead poisoning from environmental sources due to their behaviors like hand-to-mouth contact and exploratory behaviors. Choices A, C, and D are less likely to be at high risk for lead poisoning compared to young children due to differences in exposure levels and behaviors related to potential sources of lead contamination.

5. A client with heart failure is prescribed spironolactone. What is the nurse's priority intervention?

• A. Monitor the client's potassium levels closely.
• B. Assess for signs of hyperkalemia.
• C. Instruct the client to increase intake of potassium-rich foods.
• D. Increase the client’s fluid intake to prevent dehydration.

Correct answer: B

Rationale: The correct answer is B: Assess for signs of hyperkalemia. Spironolactone is a potassium-sparing diuretic, which can cause hyperkalemia (high potassium levels). Therefore, the nurse's priority intervention should be to assess the client for signs of hyperkalemia, such as muscle weakness, fatigue, and potentially dangerous cardiac arrhythmias. Monitoring potassium levels closely (choice A) is important but assessing for signs of hyperkalemia takes precedence. Instructing the client to increase intake of potassium-rich foods (choice C) can exacerbate hyperkalemia in this case. Increasing the client’s fluid intake to prevent dehydration (choice D) is not directly related to the potential side effect of spironolactone.
