ATI Pharmacology Proctored Exam

Correct Answer: D

Rationale: The healthcare professional should prioritize assessing the client's respiratory rate because respiratory depression is a life-threatening adverse effect of Morphine. Monitoring the respiratory rate allows for early detection of potential complications and timely intervention to prevent harm. Assessing urine output, bowel sounds, and pain level are important but should come after ensuring the client's respiratory status is stable as it is the most critical assessment to prevent serious complications associated with opioid use.

Correct Answer: A

Rationale: Misoprostol is contraindicated in pregnancy as it can induce labor and potentially lead to harm to the fetus. Therefore, it should not be used in pregnant clients due to its uterotonic effects. For clients with osteoarthritis, kidney stone, or urinary tract infection, Misoprostol is not contraindicated specifically for these conditions.

Correct Answer: A

Rationale: Platelets are fragile components that must be administered quickly to maintain their effectiveness and minimize the risk of clumping. The recommended administration time for platelets is within 15 to 30 minutes per unit. This rapid administration helps ensure the platelets remain viable and functional for the client receiving the transfusion. Therefore, the correct answer is to administer the transfusion within 30 minutes per unit. Choices B, C, and D are incorrect as they exceed the recommended administration time for platelets, which could compromise their efficacy and pose risks to the client.

Correct Answer: A

Rationale: Phenobarbital has a long half-life of 4 days, meaning it remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should expect to administer phenobarbital once a day to maintain therapeutic levels and effectiveness. Administering it more than once a day would lead to unnecessary dosing and potential adverse effects as the medication remains active in the body for an extended period.

Correct Answer: A

Rationale: Tamoxifen is contraindicated in clients with a history of thromboembolic events, such as deep-vein thrombosis, due to the increased risk of blood clots forming and leading to serious complications like pulmonary embolism. Clients with a history of deep-vein thrombosis are at a higher risk of recurrent thromboembolic events when taking tamoxifen, making it unsafe for such individuals. Choices B, C, and D are not contraindications for tamoxifen therapy, as migraine headaches, hypertension, and anemia do not directly interact with tamoxifen's mechanism of action or pose significant risks when used together.
