Rationale: Battery in the context of healthcare refers to the intentional and unauthorized touching of a patient. By applying a body restraint without a doctor's order, Nurse Edna has potentially committed battery against the patient. It is important for healthcare providers to obtain proper authorization before implementing any physical restraints on a patient to avoid legal liabilities such as battery.

Correct Answer: B

Rationale: The presentation described is consistent with nummular eczema, also known as discoid eczema. Nummular eczema typically presents as circular or oval-shaped patches of eczematous rash with fine scaling and central clearing. It is often pruritic and can be triggered by exposure to irritants such as new soaps or laundry detergents. The distribution on the trunk and proximal extremities is also typical for nummular eczema. Tinea corporis (ringworm) would present with a more raised, scaly, and well-defined border with central clearing. Pityriasis rosea presents with a herald patch followed by smaller oval or round lesions in a "Christmas tree" distribution. Lichen planus would present with polygonal, purplish, flat-topped papules typically located on flexural surfaces and extremities.

Correct Answer: A

Rationale: The presentation described is characteristic of acute angle-closure glaucoma. This condition typically presents with sudden-onset severe eye pain, headache, nausea, and vomiting. On examination, the affected eye may appear red due to conjunctival injection, and there may be a steamy cornea due to corneal edema. The mid-dilated, non-reactive pupil is a key finding in angle-closure glaucoma, as the iris bombe (forward movement of the peripheral iris) blocks the drainage angle, leading to increased intraocular pressure. If left untreated, acute angle-closure glaucoma can result in irreversible vision loss. Immediate intervention is crucial to lower the intraocular pressure and prevent further damage to the optic nerve. Prompt referral to an ophthalmologist for definitive treatment is necessary in cases of suspected acute angle-closure glaucoma.

Correct Answer: A

Rationale: Regular exercise is beneficial for individuals with diabetes, including your grandmother, because it helps increase metabolic rate and the consumption of glucose by the muscles. When someone exercises regularly, their muscles become more sensitive to insulin, which helps to lower blood sugar levels. This increased glucose utilization by the muscles can lead to better blood sugar control and overall improved management of diabetes. By incorporating regular exercise into her routine, your grandmother can potentially reduce the need for medications, maintain a healthier weight, and lower the risk of complications associated with diabetes.

Correct Answer: B

Rationale: Identifying persons with sputum characterized as blood stained is important in case finding for pulmonary tuberculosis (PTB) in the community. Blood stained sputum, also known as hemoptysis, is a common symptom of TB. It occurs when there is bleeding in the respiratory tract, often as a result of damage to the lungs caused by tuberculosis infection. Therefore, the presence of blood in the sputum is a significant clinical finding that should alert healthcare providers, including nurses, to the possibility of TB. Early identification and diagnosis of individuals with blood stained sputum can lead to prompt treatment and the prevention of further transmission of the disease in the community.
