The newly licensed nurse is preparing to administer a high dose of androgen to the female client. The nurse manager asks for the rationale. What is the best response by the new nurse?

Correct Answer: B

Rationale: High-dose androgens in females are used palliatively for certain breast cancers, especially hormone-sensitive ones, to suppress estrogen-driven tumor growth, easing symptoms in advanced disease. Athletic performance enhancement via androgens, while feasible, isn't clinically indicated and is illegal in regulated contexts. Brain cancer lacks evidence for androgen treatment, as it doesn't target neurological tumors. Sexual reassignment uses testosterone for masculinization, but high doses in clinical settings typically tie to cancer care, not transition. Breast cancer aligns with a recognized therapeutic use, leveraging androgens' anti-estrogenic effects, making it the most valid clinical rationale here.

Correct Answer: D

Rationale: Clopidogrel is a drug that has a therapeutic effect in preventing thromboembolic events. It is an antiplatelet agent that works by inhibiting platelet aggregation, thus reducing the risk of blood clot formation. Clopidogrel is commonly used in patients at risk for cardiovascular events such as heart attacks and strokes. Warfarin is an anticoagulant medication that also helps prevent blood clots, but it works by a different mechanism than clopidogrel. Amlodipine is a calcium channel blocker used to treat hypertension and angina, while nitroglycerine is a vasodilator used in the treatment of angina.

Correct Answer: A

Rationale: A severe adverse effect of iron is the development of iron toxicity, which can lead to symptoms such as seizures. Iron toxicity can occur when there is an excessive accumulation of iron in the body, usually from overdose or prolonged use of iron supplements. Symptoms of iron toxicity can range from mild to severe, with seizures being a serious and potentially life-threatening complication. It is important to seek medical help immediately if symptoms of iron toxicity, including seizures, occur.

Correct Answer: D

Rationale: Administering antibiotics through an infected central venous access device (CVAD) is often done to attempt to sterilize the catheter and salvage it, avoiding the need for removal and replacement. This approach is particularly useful for certain types of infections. While peripheral IV administration may be less painful or reduce infiltration risks, the primary goal in this scenario is to treat the infection directly at the source. Therefore, the correct rationale is to sterilize the catheter.

Correct Answer: B

Rationale: Ondansetron is a medication commonly used to prevent and treat nausea and vomiting, particularly in patients undergoing chemotherapy or surgery. It belongs to a class of drugs known as antiemetics, which work by blocking serotonin, a neurotransmitter that can trigger nausea and vomiting. By inhibiting the effects of serotonin, ondansetron helps to reduce the incidence and severity of these symptoms, providing a therapeutic effect for individuals experiencing nausea and vomiting.
