Correct Answer: B

Rationale: When administering IV Alteplase for a massive Pulmonary Embolism, the healthcare provider should plan to hold direct pressure on puncture sites for 10 to 30 minutes or until oozing of blood stops. This is crucial to prevent bleeding complications at the puncture sites. Choice A is incorrect because Enoxaparin is not usually administered along with Alteplase for a Pulmonary Embolism. Choice C is incorrect because Aminocaproic acid is not typically given prior to alteplase infusion in this situation. Choice D is incorrect because Alteplase should be administered within 2 hours of onset of manifestations for Pulmonary Embolism, not within 8 hours.

Correct Answer: A

Rationale: Propylthiouracil is a medication used to treat hyperthyroidism. One of the adverse effects of Propylthiouracil is bradycardia, which is a slower than normal heart rate. Since the medication works by decreasing thyroid hormone production, it can lead to hypothyroidism as a side effect, causing bradycardia. Therefore, the nurse should monitor the client for signs and symptoms of bradycardia while taking Propylthiouracil. Choices B, C, and D are incorrect because insomnia, heat intolerance, and weight loss are not typically associated adverse effects of Propylthiouracil.

Correct Answer: A

Rationale: Dexamethasone, a glucocorticoid, is indicated for clients with brain cancer to decrease inflammation and swelling. It helps reduce cerebral edema and relieve pressure caused by the tumor, ultimately alleviating headaches. The purpose of prescribing dexamethasone in this case is not to improve concentration (choice B), induce sedation (choice C), or treat depression (choice D). Methylphenidate, a stimulant, is used for conditions like ADHD, not for brain cancer. Hydroxyzine, an antihistamine, is primarily used for anxiety and itching, not for brain cancer. Amitriptyline, a tricyclic antidepressant, is used for conditions like depression and neuropathic pain, not specifically for brain cancer-related headaches.

Correct Answer: A

Rationale: The priority action for a client with Addison's disease undergoing surgery who takes hydrocortisone is to administer a supplemental dose of hydrocortisone. Acute adrenal insufficiency (adrenal crisis) is a significant risk during surgery due to the stress placed on the body. Supplemental doses help prevent acute adrenal insufficiency and ensure the client's safety during the surgical procedure. Instructing the client about coughing and deep breathing is important post-operatively but not the priority before surgery. Collecting additional information about the client's history of Addison's disease is relevant but not the priority action before surgery. Inserting an indwelling urinary catheter is not the priority action in this scenario.

Correct Answer: A

Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.
