Correct Answer: A

Rationale: The correct answer is to administer a nebulizer treatment of albuterol. In acute bronchospasm, the priority intervention is to deliver a bronchodilator like albuterol to open the airways and improve breathing. Starting an IV infusion of normal saline (Choice B) may be necessary but not the priority in this situation. Administering oxygen at 4L/min via nasal cannula (Choice C) is important but not the first intervention for bronchospasm. Positioning the client in a high Fowler's position (Choice D) can help with breathing but is not the priority over administering a bronchodilator.

Correct Answer: D

Rationale: Corrected Rationale: Blurred vision or seeing yellow halos around objects are signs of digoxin toxicity, which can be life-threatening. These symptoms indicate an overdose of digoxin, requiring immediate medical attention. Muscle weakness and fatigue (Choice A) are not typically associated with digoxin toxicity. Increased appetite and weight gain (Choice B) are not indicative of digoxin toxicity either. Nausea and vomiting (Choice C) are common side effects of digoxin but are not specific signs of toxicity. Therefore, the correct answer is to monitor for blurred vision or seeing yellow halos around objects.

Correct Answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.

Correct Answer: A

Rationale: The correct answer is to administer bronchodilators as prescribed. During an acute asthma attack, the priority is to open the airways quickly to help the client breathe more easily. Oxygen may be needed but bronchodilators take precedence as they directly target bronchoconstriction. Chest physiotherapy is not indicated in the acute phase of asthma and may exacerbate the condition. While emotional support is important, addressing the airway obstruction takes precedence in this situation.

Correct Answer: B

Rationale: Obtaining a detailed health and dietary history is crucial when assessing constipation in elders. This helps the nurse identify potential causes such as inadequate fluid intake, low fiber diet, lack of physical activity, or medications that could be contributing to constipation. A complete blood count (Choice A) is not the priority in the initial assessment of constipation. Referring to a provider for a physical examination (Choice C) would be done after gathering more information from the health history. Measuring height and weight (Choice D) is not directly relevant to assessing constipation and identifying its causes.
