Correct Answer: A

Rationale: To calculate the weight-bearing limit, we first need to convert 210 lbs to kg. To do this, we use the conversion factor 1 lb = 0.453592 kg. So, 210 lbs is equal to 210 * 0.453592 = 95.254 kg. One-third of 95.254 kg is 31.7513 kg, which can be rounded to 32 kg. Therefore, the client should bear 32 kg of weight on the right leg. Choice A is the correct answer. Choices B, C, and D are incorrect as they do not reflect the accurate calculation based on the client's weight and the prescribed weight-bearing limit.

Correct Answer: D

Rationale: The correct answer is D because hospice care provides ongoing support to families with grief even after a patient's death. Choice A is incorrect because hospice care focuses on providing comfort and symptom management rather than disease treatment and rehabilitation. Choice B is incorrect as the statement does not accurately reflect the role of a hospice provider. Choice C is incorrect; a family caregiver is not a prerequisite for admission into a hospice facility.

Correct Answer: B

Rationale: The correct answer is B: Pyrazinamide. In the treatment of tuberculosis, a combination drug therapy is usually employed. Pyrazinamide and rifampin are two key drugs used in this regimen. Acyclovir is an antiviral medication used for herpes infections, not for tuberculosis. Isoniazid is another medication used in tuberculosis treatment, but in this case, the question asked for medications to administer, and the correct choices should be those commonly used in tuberculosis combination therapy.

Correct Answer: C

Rationale: The correct answer is C: Administer regular insulin IV infusion. In diabetic ketoacidosis (DKA), the priority intervention is to rapidly decrease blood glucose levels. Administering regular insulin via IV infusion helps in lowering blood glucose effectively and quickly. Choice A, administering a dextrose 50% IV bolus, is incorrect because it would further increase blood sugar levels. Choice B, providing orange juice, is not appropriate for treating DKA as it contains sugar that will elevate blood glucose levels. Choice D, giving oral metformin, is not suitable for immediate blood glucose reduction as it acts over time and is not the first-line treatment for DKA.

Correct Answer: A

Rationale: The correct answer is A. Clinical manifestations of left-sided heart failure include pulmonary symptoms such as dyspnea, cough, and orthopnea. However, left-sided heart failure can also manifest as jugular venous distention and hepatojugular reflex due to the backflow of blood into the pulmonary circulation. Right-sided heart failure is characterized by systemic symptoms like hepatomegaly, ascites, and peripheral edema. Choice B is incorrect as it presents manifestations of right-sided heart failure. Choice C includes symptoms of left-sided heart failure. Choice D describes pulmonary congestion, which is more specific to left-sided heart failure, but it does not encompass the full range of clinical manifestations for left-sided heart failure.
