Correct Answer: D

Rationale: The symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias are indicative of hypokalemia, a condition characterized by low potassium levels. Checking the client's laboratory values for potassium will help confirm this diagnosis. Hyperphosphatemia (Choice A) is an elevated phosphate level in the blood, which is not consistent with the symptoms described. Hypocalcemia (Choice B) is a low calcium level and typically presents with different symptoms than those mentioned in the scenario. Hypermagnesemia (Choice C) is an excess of magnesium in the blood and does not align with the symptoms of muscle weakness, leg cramps, and cardiac dysrhythmias observed in the client.

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: 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.

Correct Answer: A

Rationale: The correct answer is A. When a healthcare provider witnesses a client signing an informed consent form for surgery, they are affirming that the signature on the form belongs to the client. This is crucial for ensuring patient autonomy and informed decision-making. Choices B, C, and D are incorrect because while it is important for the client to understand the risks of surgery, be aware of postoperative care instructions, and have an opportunity to ask questions, these elements are not specifically affirmed by the healthcare provider witnessing the signature.

Correct Answer: A

Rationale: When a nurse experiences reluctance to interact with a manipulative client, it is essential to address these feelings constructively. Discussing the feeling of reluctance with an objective peer or supervisor allows the nurse to gain perspective, reflect on the situation, and develop appropriate strategies for patient care. This action promotes self-awareness, professional growth, and ensures that patient care is not compromised. Option B is incorrect because avoiding the client may not address the underlying issues and can impact the therapeutic relationship. Option C is inappropriate as confronting the client may escalate the situation and hinder effective communication. Option D is not the immediate action needed in this scenario, as it focuses on behavior modification rather than addressing the nurse's feelings of reluctance.
