LPN Pharmacology Assessment A

Correct Answer: B

Rationale: An Electrocardiogram (ECG) is the most immediate and essential test to diagnose a myocardial infarction (MI) and assess the extent of heart damage. An ECG can quickly identify changes in the heart's electrical activity, allowing prompt initiation of appropriate interventions.

Correct Answer: B

Rationale: Muscle pain is a common side effect of statins like atorvastatin. It is important for the nurse to educate the client about this potential side effect, as it can indicate a serious condition called rhabdomyolysis, which requires immediate medical attention.

Correct Answer: B

Rationale: Bradycardia is a common sign of digoxin toxicity. Digoxin can cause disturbances in the heart's electrical conduction system, leading to a slower heart rate. Therefore, the nurse should closely monitor the client's heart rate for signs of bradycardia, which could indicate digoxin toxicity.

Correct Answer: C

Rationale: The correct instruction for the client before a stress test is to wear loose, comfortable clothing, and walking shoes. This is crucial as the stress test involves physical exercise, and the client should be prepared for the activity involved. Beta-blockers may need to be adjusted or held before the test as per healthcare provider's instructions. Fasting before the test is not typically required, and avoiding physical activity for 24 hours beforehand is not necessary and may interfere with the accuracy of the test results.

Correct Answer: A

Rationale: Encouraging the client to cough and deep breathe every 1 to 2 hours is crucial post-CABG surgery to prevent respiratory complications, such as atelectasis and pneumonia. These actions help to expand lung volume, clear secretions, and prevent the collapse of alveoli.
