The patient accidentally takes too much of the prescribed warfarin (Coumadin) and is readmitted to the hospital with bleeding. Which drug can the nurse anticipates administrating?

Correct Answer: D

Rationale: In the scenario described where the patient has accidentally taken too much warfarin (Coumadin) and is experiencing bleeding, the nurse can anticipate administering Vitamin K. Warfarin is an anticoagulant medication that works by inhibiting vitamin K-dependent clotting factors in the liver. By administering Vitamin K, it helps reverse the anticoagulant effect of warfarin by supplying the needed vitamin K for the production of clotting factors. This aids in the clotting process and helps to stop the bleeding that may occur due to excess warfarin in the system. Other medications listed (such as Protamine sulfate, Alteplase, Reteplase) are not specific antidotes for warfarin overdose-related bleeding but are used for different therapeutic purposes.

Correct Answer: B

Rationale: Epidermal growth factor receptor (EGFR) inhibitors commonly cause skin-related side effects, such as rash, dryness, and paronychia (nail inflammation). These side effects can lead to tissue injury and discomfort, impacting the patient's quality of life. While bone marrow suppression and reduced platelet activity are concerns with other chemotherapies, they are less common with EGFR inhibitors. Alopecia is also less frequently associated with these drugs. The nurse should prioritize monitoring and managing skin-related side effects to prevent complications and ensure patient comfort.

Correct Answer: D

Rationale: Scheduled surgery would be a contraindication for taking garlic tablets because garlic has blood-thinning properties that could potentially increase the risk of bleeding during or after surgery. This can interfere with the blood's ability to clot properly, leading to excessive bleeding and other complications during the surgical procedure. It is important to inform healthcare providers about all supplements being taken, including garlic tablets, before undergoing any surgery to ensure patient safety.

Correct Answer: B

Rationale: Long-term morphine via pump sustains certain effects. Constipation persists-tolerance doesn't fully develop to GI μ-receptor effects, unlike analgesia , euphoria , or sedation (E). Pupil dilation is incorrect; morphine causes miosis. After 22 years, constipation remains a chronic issue, reflecting opioid pharmacology.

Correct Answer: C

Rationale: Unusual nitroglycerin reactions (itching, toe pain) unwitnessed by family suggest noncompliance or psychogenic issues. Encourage use and explore reasons . Psychiatric or behavioral consults are premature. Switching or antipsychotics (E) ignores clarification. This approach ensures proper angina management.
