Rationale: The correct answer is D. A meal of turkey, sweet potato, green beans, milk, and an orange is low in sodium and suitable for a post-MI diet.

Choice C includes a bologna sandwich, which is also high in sodium compared to the other options.

Correct Answer: D

Rationale: The correct answer is to check the client's oxygen saturation level first. This action is crucial in assessing the severity of dyspnea and determining the necessity for oxygen therapy. Administering oxygen therapy without knowing the current oxygen saturation level can be inappropriate and potentially harmful. Encouraging deep breathing exercises and raising the head of the bed are important interventions, but assessing the oxygen saturation level takes precedence in managing dyspnea in a client with COPD.

Correct Answer: C

Rationale: The correct answer is C: Laxatives. Laxatives can be harsh on elderly clients, leading to dependence and potential side effects. While fiber supplements (B) and stool softeners (D) are generally safe options to promote regular bowel movements, laxatives should be used cautiously in older adults due to their potential risks. Glycerin suppositories (A) can also be a safe and effective option for managing constipation in the elderly, but laxatives should be avoided unless deemed necessary by a healthcare provider.

Correct Answer: B

Rationale: A high fever, such as 103 degrees Fahrenheit (39.5 degrees Celsius), in a client with infective endocarditis indicates that the infection may not be responding to the antibiotics and requires immediate medical evaluation. Nausea and vomiting, diffuse macular rash, and muscle tenderness are not typically associated with the ineffectiveness of antibiotic therapy in infective endocarditis.

Correct Answer: A

Rationale: The correct answer is A. Using sugar-free gum can help alleviate the metallic taste often experienced during chemotherapy treatments. Choices B, C, and D are incorrect. Drinking fluids at mealtime may worsen early satiety, foods higher in fat can exacerbate nausea, and raw fruits and vegetables may be harder for the body to digest and may pose a risk of infection for individuals with compromised immune systems.
