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. A client who delivered a 7-pound infant 12 hours ago is complaining of a severe headache. The client's blood pressure is 110/70, respiratory rate is 18 breaths/minute, heart rate is 74 beats/minute, and temperature is 98.6º F. The client's fundus is firm and one fingerbreadth above the umbilicus. What action should the healthcare team implement first?

• A. Notify the healthcare provider of the assessment findings.
• B. Determine if the client received anesthesia during delivery.
• C. Assign a licensed nurse to reassess the client's vital signs.
• D. Obtain a STAT hemoglobin and hematocrit.

Correct answer: B

Rationale: The correct action to implement first is to determine if the client received anesthesia during delivery. Anesthesia can be a potential cause of postpartum headaches. This information is crucial in assessing and managing the client's condition effectively before considering other interventions. It helps in identifying possible contributing factors to the client's complaint of a severe headache and guides the healthcare team in providing appropriate care and treatment.

3. A 40-year-old woman presents with fatigue, polyuria, and polydipsia. Laboratory tests reveal hyperglycemia and ketonuria. What is the most likely diagnosis?

• A. Type 1 diabetes mellitus
• B. Type 2 diabetes mellitus
• C. Diabetes insipidus
• D. Hyperthyroidism

Correct answer: A

Rationale: The combination of symptoms including fatigue, polyuria, polydipsia, along with laboratory findings of hyperglycemia and ketonuria strongly suggest type 1 diabetes mellitus. In type 1 diabetes mellitus, there is a deficiency of insulin leading to high blood sugar levels (hyperglycemia) and the breakdown of fats producing ketones, causing ketonuria. Type 2 diabetes mellitus typically presents differently and is more common in older individuals. Diabetes insipidus is characterized by excessive thirst and urination due to a deficiency of antidiuretic hormone, distinct from the provided clinical scenario. Hyperthyroidism may present with some overlapping symptoms like fatigue, but it does not account for the specific laboratory findings of hyperglycemia and ketonuria seen in this case.

4. A young adult female client is seen in the emergency department for a minor injury following a motor vehicle collision. She states she is very angry at the person who hit her car. What is the best nursing response?

• A. You are lucky to be alive. Be grateful no one was killed.'
• B. I understand your car was not seriously damaged.'
• C. You are upset that this incident has brought you here.'
• D. Have you ever been in the emergency department before?'

Correct answer: C

Rationale: Validating the client's feelings can help her express and manage her emotions effectively.

5. A client with a history of myocardial infarction (MI) is prescribed atorvastatin (Lipitor). Which outcome indicates that the medication is effective?

• A. Increased blood pressure.
• B. Lowered cholesterol levels.
• C. Decreased heart rate.
• D. Improved liver function.

Correct answer: B

Rationale: The correct answer is B: Lowered cholesterol levels. Atorvastatin is a medication commonly prescribed to lower cholesterol levels, which is crucial in reducing the risk of further cardiovascular events, including myocardial infarction (MI). Monitoring cholesterol levels is essential to assess the effectiveness of atorvastatin therapy and its role in preventing future cardiac complications. Choices A, C, and D are incorrect because increased blood pressure, decreased heart rate, and improved liver function are not direct indicators of atorvastatin's effectiveness in a client with a history of MI.
