Correct Answer: B

Rationale: When a patient uses an in-the-canal hearing aid, cerumen buildup is a critical issue that needs to be regularly assessed. Cerumen can easily block the sound passage and affect the functionality of the hearing aid. Assessing and managing cerumen buildup is a priority to ensure the proper functioning of the hearing aid. Eyeglass usage, type of physical exercise, and excessive moisture problems are not directly related to the specific issue of cerumen buildup in in-the-canal hearing aids, making them lower priority assessments in this context.

Correct Answer: A

Rationale: The correct answer is A. A 16-year-old who is married can legally sign an informed consent form. In this case, being married at 16 may indicate legal emancipation or the ability to consent to medical treatment. Choice B is incorrect because having schizophrenia doesn't automatically imply incapacity to provide informed consent. Choice C is incorrect as an adoptive parent does not have the legal authority to provide consent for medical treatment on behalf of a child without proper documentation. Choice D is incorrect as a 17-year-old mother would generally not have the legal capacity to give consent for her toddler, as parental consent is usually required for minors.

Correct Answer: C

Rationale: To calculate the dosage correctly, the weight in pounds must first be converted to kilograms. 220 lb / 2.2 = 100 kg. Then, multiply the weight in kg by the dosage of 2 mg/kg: 2 mg/kg 100 kg = 200 mg. Therefore, the correct dosage to administer is 200 mg, which is closest to option A. Option C (160 mg) is incorrect because it does not match the calculated dosage. Options B (100 mg) and D (180 mg) are also incorrect as they do not align with the correct calculation.

Correct Answer: A

Rationale: The correct answer is A. Shifting weight to the unaffected leg when descending stairs is crucial for maintaining balance and safety. This technique helps prevent falls and distributes weight appropriately. Choices B, C, and D are incorrect because using crutches to support the weight on the injured leg, leading with the injured leg when ascending stairs, and keeping crutches under the arms are all potentially unsafe practices that could lead to further injury or accidents.

Correct Answer: A

Rationale: The correct technique for nasotracheal suctioning is to apply intermittent suction when withdrawing the catheter. This method helps prevent damage to the mucosa and is the recommended approach. Continuous suction during insertion (choice B) can cause trauma to the airway lining. Applying suction only during insertion (choice C) is not sufficient for effective removal of secretions. Inserting the catheter while the client is exhaling (choice D) does not follow the standard procedure for nasotracheal suctioning.
