ATI Pharmacology

Correct Answer: D

Rationale: Levothyroxine should be initiated at a low dose and titrated gradually over several weeks to achieve therapeutic levels. This approach helps to minimize the risk of adverse effects, particularly in older adult clients who may be more sensitive to medication changes. Starting at a low dose allows for close monitoring of the client's response and adjustment of the dosage as needed to optimize treatment outcomes.

Correct Answer: A

Rationale: Tinnitus should be reported by the client as it can be indicative of ototoxicity, an adverse effect associated with cisplatin therapy. Ototoxicity can result in damage to the inner ear structures, leading to hearing problems. Therefore, prompt reporting of tinnitus is essential for early intervention and prevention of potential complications.

Correct Answer: C

Rationale: Ezetimibe is contraindicated in patients with active moderate-to-severe liver disorders, such as active hepatitis C, especially when they are already taking a statin like simvastatin. This combination can increase the risk of liver problems and is not recommended due to the potential for further liver damage.

Correct Answer: A

Rationale: The correct instruction is to remove the nitroglycerin patch each evening to prevent tolerance. This allows for a 10- to 12-hour nitrate-free period daily, reducing the risk of developing tolerance to nitroglycerin. Cutting the patch in half, taking it off for a headache, or applying a new patch every 48 hours are not recommended practices for managing angina with nitroglycerin patches.

Correct Answer: A

Rationale: It is important for the nurse to educate the client about the increased risk for a myocardial infarction when taking Celecoxib due to its effect on suppressing vasodilation, which can lead to this adverse cardiovascular event. Monitoring for signs of heart issues and discussing the importance of seeking prompt medical attention if symptoms occur is crucial in the patient's education.
