Nursing Elites

1. A patient with atrial fibrillation is prescribed warfarin. Which laboratory test should the nurse monitor to assess the effectiveness of the medication?

• A. Complete blood count (CBC)
• B. Prothrombin time (PT)/INR
• C. Partial thromboplastin time (PTT)
• D. Serum potassium level

Correct answer: B

Rationale: The correct answer is B: Prothrombin time (PT)/INR. Warfarin affects the clotting ability of the blood by inhibiting vitamin K-dependent clotting factors. Monitoring the prothrombin time (PT) and international normalized ratio (INR) is crucial to assess the effectiveness and safety of warfarin therapy. These tests help determine if the patient is within the desired anticoagulation range to prevent either clotting issues or excessive bleeding.

2. The healthcare provider is caring for a patient who is taking warfarin (Coumadin). Which laboratory value should the healthcare provider monitor closely?

• A. Platelet count.
• B. Prothrombin time (PT).
• C. Hemoglobin level.
• D. White blood cell count.

Correct answer: B

Rationale: Corrected Rationale: When caring for a patient on warfarin, monitoring prothrombin time (PT) is crucial. PT helps assess the blood's ability to clot properly, ensuring the patient maintains therapeutic anticoagulation levels while minimizing bleeding risks. Platelet count (Choice A) is important but not the most critical for warfarin therapy. Hemoglobin level (Choice C) and white blood cell count (Choice D) are not directly related to monitoring the effects of warfarin.

3. A healthcare professional is assessing a client with severe dehydration. Which finding indicates a need for immediate intervention?

• A. Heart rate of 110 beats per minute.
• B. Blood pressure of 90/60 mm Hg.
• C. Urine output of 20 ml/hour.
• D. Dry mucous membranes.

Correct answer: C

Rationale: A urine output of 20 ml/hour indicates severe dehydration and impaired renal function. This finding suggests a critical state where the kidneys are conserving water, leading to reduced urine output. Immediate intervention is required to restore fluid balance and prevent further complications associated with severe dehydration. Choice A, a heart rate of 110 beats per minute, may indicate dehydration but is not as severe as the critically low urine output. Choice B, a blood pressure of 90/60 mm Hg, can be seen in dehydration but is not as concerning as the extremely low urine output. Choice D, dry mucous membranes, is a common sign of dehydration but does not require immediate intervention compared to the severely reduced urine output.

4. A client who has Type 1 diabetes and is at 10-weeks gestation comes to the prenatal clinic complaining of a headache, nausea, sweating, feeling shaky, and being tired all the time. What action should the nurse take first?

• A. Check the blood glucose level.
• B. Draw blood for a Hemoglobin A1C.
• C. Assess urine for ketone levels.
• D. Provide the client with a protein snack.

Correct answer: A

Rationale: The correct action for the nurse to take first is to check the client's blood glucose level. This is crucial to determine if the symptoms are a result of hypoglycemia or hyperglycemia, which requires immediate attention to maintain the client's health and the health of the developing fetus.

5. The healthcare provider is assessing a client with chronic obstructive pulmonary disease (COPD). Which finding should the provider expect?

• A. Increased anteroposterior chest diameter.
• B. Decreased respiratory rate.
• C. Dull percussion sounds over the lungs.
• D. Hyperresonance on chest percussion.

Correct answer: A

Rationale: The correct answer is A: Increased anteroposterior chest diameter. The increased anteroposterior chest diameter, often referred to as a barrel chest, is a common finding in clients with COPD due to hyperinflation of the lungs. This occurs because of the loss of lung elasticity and air trapping, leading to a more rounded chest shape. Choices B, C, and D are incorrect. Decreased respiratory rate is not typically associated with COPD; instead, an increased respiratory rate may be seen due to the body's compensatory mechanisms. Dull percussion sounds and hyperresonance on chest percussion are not characteristic findings in COPD. Dull percussion sounds may be indicative of consolidation or pleural effusion, while hyperresonance is more commonly associated with conditions like emphysema.
