Which type of elder mistreatment is demonstrated by a caregiver leaving a nursing home resident alone in his room for long periods at a time with no opportunity for social stimulation?

A. This option describes a phenomenon seen in heparin-induced thrombocytopenia (HIT), not in immune thrombocytopenic purpura (ITP). In HIT, antibodies against the PF4-heparin complex can cause platelet activation and aggregation, leading to thrombocytopenia. However, this is not characteristic of ITP.
B. Abnormally long von Willebrand factor is seen in von Willebrand disease (VWD), not in ITP. VWD is a bleeding disorder caused by deficiency or dysfunction of von Willebrand factor, which plays a key role in platelet adhesion and aggregation. It is not typically associated with ITP.

C. ADAMTS13 deficiency is characteristic of thrombotic thrombocytopenic purpura (TTP), not ITP. TTP is a rare blood disorder where small blood clots form in blood vessels throughout the body, leading to thrombocytopenia (low platelet count) and other complications. It is distinct from ITP.
D. In immune thrombocytopenic purpura (ITP), the immune system mistakenly attacks and destroys platelets, leading to a low platelet count. Antibodies, particularly anti-platelet antibodies such as anti-GP IIb/IIIa or anti-GP Ib/IX, coat the surface of platelets. These antibody-coated platelets are recognized and destroyed by macrophages in the spleen and liver, contributing to thrombocytopenia.

A. Headache is a common side effect of nitroglycerin due to its vasodilatory effects, especially in the head. Most headaches associated with nitroglycerin are mild and transient. Patients are generally advised to continue using the medication as prescribed unless the headache is severe or persistent.
B. Nitroglycerin tablets are used for the immediate relief of angina symptoms. If the first tablet does not adequately relieve chest pain within 5 minutes, the patient can take a second tablet. If the pain persists after the second tablet, emergency medical attention should be sought. However, it's important to note that the maximum number of tablets that can be taken within a short period should be specified by the healthcare provider, typically 2 or 3 tablets in 15 to 30 minutes.
C. Nitroglycerin can cause orthostatic hypotension, which is a drop in blood pressure upon standing up. This can lead to dizziness or fainting. Therefore, patients should be advised to stand up slowly after taking nitroglycerin to minimize the risk of falls or injury.
D. Nitroglycerin tablets are sensitive to light, heat, and moisture, which can reduce their effectiveness over time. Therefore, it's recommended to replace nitroglycerin tablets every 3 to 6 months to ensure potency and effectiveness.
