Correct Answer: B

Rationale: The correct action for the nurse to take is to infuse the KCl at a rate of 10 mEq/hour. Rapid IV infusion of KCl can lead to cardiac arrest due to its potential for causing hyperkalemia. While KCl can be administered through peripheral veins, central venous lines are not necessary unless specified. It is crucial to continue cardiac monitoring during potassium infusion to promptly identify and manage any potential dysrhythmias that may occur.

Correct Answer: A

Rationale: Viewing the EHR of a client who is not under your care is a violation of HIPAA regulations, regardless of the client's social status or your curiosity. The appropriate action to take in this situation is to communicate the colleague's actions to the unit charge nurse. The charge nurse can then escalate the issue through the appropriate channels within the organization. Reporting to the charge nurse ensures that the incident is handled internally and in accordance with organizational policies and procedures. Sending an email to facility administration, writing an anonymous complaint to a professional website, or posting a comment on a staff discussion board are not the recommended actions as they may not address the issue effectively and could potentially violate confidentiality further.

Correct Answer: A

Rationale: The correct answer is A - 'The patient is experiencing laryngeal stridor.' Hypocalcemia can cause laryngeal stridor, which may lead to respiratory arrest. Rapid action is required to correct the patient's calcium level to prevent a life-threatening situation. Choices B, C, and D are also symptoms of hypocalcemia, but laryngeal stridor takes precedence due to its potential to quickly progress to a critical condition.

Correct Answer: B

Rationale: The correct answer is to check the patient's blood pressure. Given the patient's symptoms of frequent, watery stools, there is a concern for fluid volume deficit. Assessing the blood pressure helps determine the patient's perfusion status, which is crucial in managing fluid volume deficits. While obtaining baseline weight, drawing blood for serum electrolyte levels, and asking about extremity numbness or tingling are important assessments, checking the blood pressure takes precedence as it provides immediate information on the patient's circulatory status.

Correct Answer: C

Rationale: The correct answer is C: 'Around the nostrils.' Constant pressure from the tubing may create skin damage to the areas of skin and bony prominences the nasal cannula will be resting on, including around the nostrils. Choice A, 'Tops of the ears,' is incorrect as the cannula does not rest on the ears. Choice B, 'Bridge of the nose,' is incorrect because the cannula typically rests under the nose. Choice D, 'Over the cheeks,' is also incorrect as the cannula does not typically rest on the cheeks.
