Nursing Elites

1. A client with a history of atrial fibrillation is receiving warfarin (Coumadin) therapy. Which laboratory result indicates that the therapy is effective?

• A. International normalized ratio (INR) of 1.0.
• B. Prothrombin time (PT) of 12 seconds.
• C. Partial thromboplastin time (PTT) of 60 seconds.
• D. International normalized ratio (INR) of 2.5.

Correct answer: D

Rationale: An International Normalized Ratio (INR) of 2.5 indicates that warfarin therapy is within the therapeutic range for a client with atrial fibrillation. A lower INR (such as 1.0) would suggest subtherapeutic levels, risking blood clots. Prothrombin time (PT) and partial thromboplastin time (PTT) are not specific to monitoring warfarin therapy.

2. The healthcare provider is caring for a client with hyperparathyroidism. Which laboratory result requires immediate intervention?

• A. Serum calcium of 11 mg/dL.
• B. Serum phosphorus of 3 mg/dL.
• C. Serum magnesium of 1.8 mg/dL.
• D. Serum albumin of 4 g/dL.

Correct answer: A

Rationale: A serum calcium level of 11 mg/dL indicates hypercalcemia, which can be a complication of hyperparathyroidism and requires immediate intervention. Hypercalcemia can lead to serious complications such as cardiac dysrhythmias, renal failure, and neurologic symptoms. Monitoring and managing serum calcium levels are crucial in clients with hyperparathyroidism. Serum phosphorus, magnesium, and albumin levels are important to assess in clients with hyperparathyroidism, but they do not require immediate intervention as hypercalcemia poses a more urgent risk.

3. The nurse obtains a heart rate of 92 and a blood pressure of 110/76 before administering a scheduled dose of verapamil (Calan) for a client with atrial flutter. Which action should the nurse implement?

• A. Administer the dose as prescribed.
• B. Hold the medication.
• C. Call the healthcare provider.
• D. Repeat the vital signs in 30 minutes.

Correct answer: A

Rationale: The correct action is to administer the dose as prescribed. Verapamil slows sinoatrial nodal automaticity and delays atrioventricular nodal conduction, which helps in slowing the ventricular rate. The heart rate of 92 and blood pressure of 110/76 are within an acceptable range for administering verapamil in a client with atrial flutter. Holding the medication, calling the healthcare provider, or repeating the vital signs in 30 minutes are not necessary based on the vital signs obtained and the action of verapamil in this scenario.

4. A public health nurse is planning an educational campaign to reduce the incidence of hypertension in the community. Which group should be the primary target of this campaign?

• A. adolescents
• B. young adults
• C. middle-aged adults
• D. older adults

Correct answer: C

Rationale: The correct answer is C, middle-aged adults. Middle-aged adults are at a higher risk for developing hypertension due to lifestyle factors and aging. Targeting this group for preventive measures such as dietary changes, exercise, and stress management can have a significant impact on reducing the incidence of hypertension. Choices A, B, and D are less appropriate targets as adolescents generally have lower rates of hypertension, young adults are less likely to be affected by hypertension at this stage, and older adults may already have established hypertension or comorbidities that could make prevention more challenging.

5. The healthcare professional is planning a health fair to promote cancer awareness and prevention. Which activity is most likely to increase participation?

• A. offering free cancer screenings
• B. distributing pamphlets on cancer prevention
• C. hosting a guest speaker who is a cancer survivor
• D. providing informational booths on different types of cancer

Correct answer: A

Rationale: Offering free cancer screenings is the most likely activity to increase participation in the health fair. Providing direct services such as screenings not only attracts participants but also promotes early detection, which is crucial in cancer prevention. Distributing pamphlets, hosting a guest speaker, or providing informational booths are informative but may not have the same impact in driving participation as the opportunity for free screenings.
