Correct Answer: C

Rationale: The correct answer is C: Medicare. Title XVII of the Social Security Act of 1965 created the Medicare Program to provide medical insurance for individuals who are 65 years or older, disabled, or have permanent kidney failure. Medicare is the appropriate agency to refer a 66-year-old woman who is retiring and losing her employment-based health insurance. Choice A, the Woman, Infants, and Children program, is not suitable for this scenario as it provides assistance for low-income pregnant women, breastfeeding women, and young children. Choice B, Medicaid, is a program that helps individuals with low income and resources cover medical costs, which may not be applicable to this woman's situation. Choice D, the Consolidated Omnibus Budget Reconciliation Act provision, known as COBRA, allows employees to continue their group health insurance coverage after leaving their job but may not be the best option for this woman in this case.

Correct Answer: B

Rationale: The correct answer is B: History of cardiac arrhythmia. Clozapine can lead to severe cardiovascular problems, making it crucial to report any history of cardiac arrhythmia to the healthcare provider before administering the medication. Choices A, C, and D are less concerning in this context as they are not directly associated with potential serious complications related to clozapine use.

Correct Answer: B

Rationale: The correct intervention in this situation is to infuse a rapid IV normal saline bolus. The client's drop in blood pressure to 60/40 mm Hg after nitroglycerin administration indicates hypotension, which may suggest a right ventricular infarction. Normal saline bolus helps to increase intravascular volume, improve cardiac output, and support blood pressure. Administering a second dose of nitroglycerin would further decrease blood pressure. External chest compressions are not indicated as the client's heart is still beating, and there is no indication for CPR. Giving an antiemetic medication is not the priority in this situation where hypotension is the main concern.

Correct Answer: A

Rationale: The correct action for the nurse to implement is to digitally check the client for a fecal impaction. In this scenario, the client's presentation of frequent small amounts of liquid stool after a period of no bowel movement suggests a possible impaction. By performing a digital examination, the nurse can assess for the presence of a blockage that may be causing the symptoms. Administering a laxative (Choice B) without assessing for impaction can worsen the situation. Increasing fluid intake (Choice C) is generally beneficial for bowel health but may not address the immediate issue of a potential impaction. Performing a digital rectal examination (Choice D) is similar to Choice A but is more focused on assessing the rectum itself rather than checking for an impaction.

Correct Answer: C

Rationale: Maintaining a patent airway is crucial for clients with myasthenia gravis because muscle weakness can affect the muscles responsible for breathing, potentially leading to respiratory compromise. Encouraging rest, administering medication, and monitoring for respiratory infections are important aspects of care but do not take precedence over ensuring a patent airway for adequate oxygenation.
