Correct Answer: A

Rationale: The correct answer is A: Muscle weakness. After unilateral adrenalectomy, there is a risk of hyperkalemia due to decreased aldosterone production. Aldosterone helps regulate potassium levels in the body. Muscle weakness is a common symptom of hyperkalemia as high potassium levels can affect muscle function. Diaphoresis, tremors, and constipation are not typically associated with hyperkalemia. Diaphoresis is excessive sweating, tremors are involuntary muscle movements, and constipation is difficulty passing stool. These symptoms are not directly related to potassium imbalance.

Correct Answer: D

Rationale: The correct answer is D: Restricting fluids. In SIADH, there is an excess of antidiuretic hormone leading to water retention and dilutional hyponatremia. Restricting fluids helps to prevent further water retention and hyponatremia. Rapid IV fluid infusion (A) worsens the condition by further diluting sodium levels. Administering glucose-containing IV (B) is not directly related to treating SIADH. Encouraging increased oral intake (C) can exacerbate the condition by increasing fluid intake.

Correct Answer: B

Rationale: The correct answer is B because a Snellen chart reading of 20/80 means the patient can see at 20 feet what a normal eye can see at 80 feet. This indicates that the patient's vision is below average. Choice A is incorrect because it reverses the numerator and denominator. Choice C is incorrect because it does not accurately represent the Snellen chart findings. Choice D is incorrect because 20/80 is not considered normal vision.

Correct Answer: C

Rationale: The correct answer is C. When the client is in a state of respiratory arrest, immediate medical intervention is required. Discontinuing oxygen administration and notifying the physician is crucial to address the life-threatening situation. A: Improving color is a positive sign. B: Decreased consciousness may indicate a need for further assessment but does not require immediate discontinuation of oxygen. D: Inability to use the diaphragm may require intervention but does not indicate an immediate threat as respiratory arrest does.

Correct Answer: A

Rationale: The correct answer is A: Diagnosis. After reviewing the patient's database and identifying concerning signs such as not voiding for over 8 hours, abnormal kidney function, and decreased oral intake, the nurse must move to the diagnosis step. In this step, the nurse will analyze the data collected to identify the patient's actual and potential health problems. This will help the nurse formulate appropriate nursing diagnoses and develop a plan of care to address the identified issues. Choice B (Planning) comes after the diagnosis step, where specific goals and interventions are established; Choice C (Implementation) follows planning and involves executing the planned interventions; Choice D (Evaluation) is the final step where the nurse assesses the effectiveness of the interventions. In this scenario, the nurse must first determine the patient's health problems before proceeding to planning, implementing, and evaluating care.
