ATI Pharmacology Proctored Exam 2019

Correct Answer: B

Rationale: When a client is prescribed Digoxin, monitoring potassium levels is crucial as hypokalemia can increase the risk of Digoxin toxicity. Low potassium levels can potentiate the effects of Digoxin on the heart, leading to toxicity. Therefore, regular monitoring of potassium levels helps in preventing adverse effects and ensuring the safe use of Digoxin.

Correct Answer: A

Rationale: Propranolol is a nonselective beta-adrenergic blocker that blocks both beta1 and beta2 receptors. Blocking beta2 receptors in the lungs can lead to bronchoconstriction, making it unsuitable for clients with asthma. Therefore, asthma is a contraindication for taking Propranolol.

Correct Answer: A

Rationale: To calculate the volume to administer, divide the desired dose by the available concentration. In this case, (80 mg / 10 mg/mL) = 8 mL.

Correct Answer: D

Rationale: The correct instruction is to apply the Nitroglycerin transdermal patch to a hairless area of skin. This ensures proper absorption of the medication. It is important to rotate the application site daily to prevent skin irritation and tolerance development. Applying the patch to the same site each day can lead to decreased efficacy and potential skin reactions. Removing the patch at night is not necessary as the patches are usually worn continuously to provide constant medication delivery. Covering the patch with a heating pad can increase the absorption of the medication and lead to an overdose, which is not recommended.

Correct Answer: B

Rationale: The nurse should instruct the client to report dyspnea because it can indicate pulmonary toxicity, a severe adverse effect of docetaxel. Dyspnea may suggest a potential serious condition that needs prompt evaluation and intervention to prevent complications.
