Correct Answer: D

Rationale: In the scenario presented, the correct action for the nurse to take when caring for a client with a verbal prescription for restraints due to acute mania is to document the client's condition every 15 minutes. Documenting at regular intervals is essential to monitor the client's well-being, assess the effects of the restraints, and ensure the client's safety. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary as the focus should be on monitoring the client's condition. Checking the client's peripheral pulse every 30 minutes (Choice B) is important but not as crucial as documenting the overall condition. Obtaining a prescription for restraints within 4 hours (Choice C) is not the immediate action needed when a verbal prescription is already obtained.

Correct Answer: A

Rationale: The correct answer is A: Increased creatinine. In chronic kidney disease, the kidneys are unable to filter waste effectively, leading to a buildup of creatinine in the blood. This results in increased creatinine levels in laboratory tests. Choice B, increased hemoglobin, is not typically associated with chronic kidney disease. Choice C, increased bicarbonate, is also not a common finding in chronic kidney disease; in fact, metabolic acidosis with decreased bicarbonate levels is more common. Choice D, increased calcium, is not expected in chronic kidney disease; instead, calcium levels may be low due to impaired kidney function.

Correct Answer: D

Rationale: The correct answer is D: a low WBC count. Clozapine can suppress bone marrow function, leading to a decreased white blood cell count. This condition, known as agranulocytosis, increases the risk of severe infections. Monitoring WBC counts is essential during clozapine therapy. Choices A, B, and C are within normal ranges and are not contraindications for administering clozapine.

Correct Answer: C

Rationale: During an acute asthma exacerbation, the priority is to quickly relieve bronchoconstriction and improve airflow. Albuterol is a short-acting bronchodilator that acts rapidly to dilate the airways, making it the first-line medication for acute symptom relief. Montelukast is a leukotriene receptor antagonist used for long-term asthma control, not for immediate relief. Salmeterol is a long-acting bronchodilator used for maintenance therapy, not for acute exacerbations. Fluticasone is an inhaled corticosteroid that reduces airway inflammation and is also used for long-term control, not for immediate relief during an exacerbation.

Correct Answer: C

Rationale: The correct answer is C. Monitoring blood glucose levels before meals and at bedtime is crucial for managing type 2 diabetes mellitus. Option A is incorrect because limiting protein intake is not a primary focus for diabetes management. Option B is unrelated to diabetes management and focuses on pain relief. Option D mentions reducing carbohydrate intake, which is a common dietary recommendation for managing blood sugar levels, but it is not as specific as monitoring blood glucose levels at key times.
