Correct Answer: D

Rationale: Assessing pupil responses is crucial in a client with hypertensive crisis to monitor for signs of increased intracranial pressure, which can indicate potential neurological complications. While heart rate, pedal pulses, and lung sounds are important assessments, they do not take precedence over neurological assessments in this critical situation.

Correct Answer: C

Rationale: The correct answer is C: Chloride. Chloride levels are typically low in cases of hyponatremia, as it often accompanies sodium loss. Magnesium (choice A) is not directly related to hyponatremia. Calcium (choice B) and Potassium (choice D) levels are usually not significantly affected by hyponatremia, making them less likely to be below the expected reference range in this scenario.

Correct Answer: B

Rationale: The observation of the client's entire body turning a bright red color during an excretory urogram indicates a severe reaction to the dye, which is a significant complication. This reaction is likely due to an allergic response and requires immediate medical attention. The other choices do not signify a severe complication: choice A could be a normal taste sensation related to the procedure, choice C may indicate a mild reaction, and choice D could be a common side effect of nausea without indicating a severe complication requiring immediate intervention.

Correct Answer: A

Rationale: Assessing the client's usual pattern of activity is crucial as it helps the nurse understand the client's current level of physical activity, any limitations, and areas needing improvement. This information is essential to create a safe and effective exercise plan tailored to the client's specific needs. Choice B, assisting the client in developing a healthy eating plan, is important but not the first step when the client's immediate goal is to start an exercise program. Encouraging the client to join a support group may be beneficial for motivation and emotional support but is not the priority at this stage. Providing a list of signs and symptoms to report to the provider is important for client education but is not the initial step when the client expresses a desire to begin an exercise program.

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.
