Nursing Elites

1. A client with a history of angina pectoris reports chest pain after climbing stairs. What should be the nurse's first action?

• A. Administer oxygen.
• B. Administer nitroglycerin.
• C. Sit the client down and rest.
• D. Check the client's blood pressure.

Correct answer: C

Rationale: The correct action for a client experiencing anginal pain, like chest pain after climbing stairs, is to sit the client down and have them rest. Resting reduces myocardial oxygen demand, which can help relieve anginal pain. Administering oxygen or nitroglycerin may be appropriate interventions after the client has been seated and rested. Checking the client's blood pressure is important but not the immediate priority when a client is experiencing anginal pain. Therefore, the first action should be to sit the client down and allow them to rest.

2. A client has a new prescription for methotrexate. Which of the following instructions should the nurse include?

• A. Avoid consuming dairy products.
• B. Take the medication on an empty stomach.
• C. Increase your intake of folic acid.
• D. Monitor for signs of hyperglycemia.

Correct answer: C

Rationale: Increasing folic acid intake is crucial when taking methotrexate because the medication can lead to folic acid deficiency. Folic acid supplementation helps counteract this deficiency and reduces the risk of adverse effects associated with methotrexate therapy. Choices A, B, and D are incorrect. Avoiding dairy products is not specifically necessary for methotrexate therapy. Methotrexate is usually taken with food to reduce gastrointestinal side effects, so taking it on an empty stomach is not recommended. Monitoring for signs of hyperglycemia is not directly related to methotrexate use.

3. A client who had a myocardial infarction (MI) two days ago reports chest pain radiating to the left arm. What should the nurse do immediately?

• A. Administer morphine
• B. Obtain an electrocardiogram (ECG)
• C. Apply oxygen via nasal cannula
• D. Administer sublingual nitroglycerin

Correct answer: B

Rationale: Obtaining an ECG is crucial in this situation because it helps in assessing for potential complications, such as a recurrent MI or ongoing ischemia. This diagnostic test provides valuable information to guide further interventions and treatment. Administering morphine, oxygen, or nitroglycerin may be necessary but obtaining an ECG takes precedence to evaluate the cardiac status and determine the appropriate course of action. Administering morphine without assessing the current cardiac status through an ECG can mask important diagnostic clues. Applying oxygen and administering nitroglycerin are supportive measures that can follow the ECG to address potential hypoxia and ischemic pain relief, respectively.

4. A client with a history of atrial fibrillation is prescribed warfarin (Coumadin). Which laboratory value should the nurse monitor to assess the effectiveness of the medication?

• A. Activated partial thromboplastin time (aPTT)
• B. Prothrombin time (PT) and international normalized ratio (INR)
• C. Platelet count
• D. Erythrocyte sedimentation rate (ESR)

Correct answer: B

Rationale: Prothrombin time (PT) and international normalized ratio (INR) are the laboratory values used to monitor the effectiveness of warfarin therapy. These values help ensure that the client is within the therapeutic range for anticoagulation. PT measures the time it takes for blood to clot, while INR standardizes PT results to minimize variations between laboratories. Monitoring these values is crucial to prevent complications such as bleeding or clot formation. Activated partial thromboplastin time (aPTT) (Choice A) is more commonly used to monitor heparin therapy. Platelet count (Choice C) assesses the number of platelets in the blood and is not specific to warfarin therapy. Erythrocyte sedimentation rate (ESR) (Choice D) is a non-specific marker of inflammation and is not used to monitor the effectiveness of warfarin therapy.

5. The client with a diagnosis of heart failure is receiving furosemide (Lasix). Which laboratory value is most important for the nurse to monitor?

• A. Blood glucose
• B. Serum sodium
• C. Serum potassium
• D. Blood urea nitrogen (BUN)

Correct answer: C

Rationale: The correct answer is C: Serum potassium. When a client is receiving furosemide, a loop diuretic, it can lead to potassium loss. Monitoring the serum potassium levels is crucial to prevent life-threatening complications such as cardiac arrhythmias. Blood glucose (Choice A) is not directly impacted by furosemide. Serum sodium (Choice B) may be affected, but monitoring potassium is more critical due to the risk of arrhythmias. Blood urea nitrogen (BUN) (Choice D) is important for assessing kidney function but is not the most crucial value to monitor in a client taking furosemide.
