Correct Answer: B

Rationale: The correct answer is B: Providing wigs and other coping resources helps clients manage the emotional effects of chemotherapy-related hair loss. Encouraging the client to cut their hair short before chemotherapy (Choice A) is not necessary as hair loss may still occur. Assuring the client that hair loss will be minimal (Choice C) may provide false hope as hair loss is a common side effect of chemotherapy. Offering medication to reduce hair loss (Choice D) is not a typical approach as chemotherapy-related hair loss is often an expected side effect that cannot be entirely prevented with medication.

Correct Answer: B

Rationale: The correct answer is B: Prioritize a chest x-ray for the client. When a client presents with severe dyspnea, a chest x-ray should be prioritized as it helps in assessing the lungs and heart, which are crucial in cases of respiratory distress. Echocardiograms are more focused on assessing heart function and may not provide immediate information needed in cases of dyspnea. CT scans and MRIs are more detailed imaging studies that are not typically the first-line diagnostic tests for severe dyspnea.

Correct Answer: A

Rationale: The correct answer is to maintain the patient's oxygen saturation above 90% when caring for a patient with COPD. In COPD, impaired gas exchange leads to decreased oxygen levels in the blood. By ensuring oxygen saturation remains above 90%, healthcare providers can prevent hypoxia and its complications. Administering bronchodilators as prescribed (Choice B) is an important intervention in managing COPD symptoms, but it is not the primary goal. Improving the patient's nutritional intake (Choice C) and encouraging the patient to limit physical activity (Choice D) are also essential aspects of COPD management, but they are not the primary goal when caring for a patient with this condition.

Correct Answer: A

Rationale: The correct answer is to check the patient's heart rate before administering digoxin. Digoxin is a medication that primarily affects cardiac function. Monitoring the heart rate is crucial because digoxin can cause arrhythmias or worsen existing heart rhythm abnormalities. Assessing blood pressure may also be important but is secondary to evaluating the heart rate when administering digoxin. Ensuring the patient has eaten before administration is not directly related to the safe administration of digoxin. Monitoring the patient's weight is not a priority action before administering digoxin.

Correct Answer: C

Rationale: The correct answer is C. According to the gate control theory, meditation helps relieve pain by blocking pain impulses from coming through the gate in the central nervous system. Choice A is incorrect as meditation does not directly alter the chemical composition of pain neuroregulators. Choice B is incorrect because meditation does not stop the occurrence of pain stimuli. Choice D is incorrect as meditation does not open the gate but rather closes it to block pain impulses.
