Correct Answer: B

Rationale: The correct answer is B: 'Wear a supportive bra during the day and at night.' Wearing a supportive bra is essential for individuals with fibrocystic breasts as it helps relieve discomfort by providing necessary support to reduce strain on breast tissue. Option A is incorrect as high-calcium foods are not directly related to symptom relief in fibrocystic breasts. Option C is not the first-line recommendation and may not address the underlying issue. Option D, performing regular breast massage, is not typically recommended and may not provide significant relief for fibrocystic breast symptoms.

Correct Answer: A

Rationale: The correct answer is A: 83. The pharmacy provided the infusion at 10 million units per liter, which requires a rate of 83 mL/hour. To calculate this, multiply the dosage by the volume of the IV solution and divide by the concentration of the IV solution in million units: 10 million units per liter x 8.3 L = 83 mL/hour. Choices B, C, and D are incorrect as they do not align with the calculation based on the given information.

Correct Answer: A

Rationale: The correct answer is A: Recent compliance with prescribed medications. In a client with chronic emphysema experiencing acute symptoms, it is crucial to assess medication compliance as it directly impacts the management of the condition and could contribute to the current presentation. Ensuring that the client has been taking their prescribed medications can provide vital information to guide further treatment. Choices B, C, and D, although important in a comprehensive assessment, are not as immediately crucial as assessing medication compliance in this emergency situation.

Correct Answer: B

Rationale: After a lumbar puncture, a severe headache is often caused by cerebrospinal fluid leakage. Elevating the head of the bed or having the client lie flat can reduce cerebrospinal fluid pressure and alleviate the headache. These positions help prevent further fluid loss and relieve discomfort. While acetaminophen or caffeine may help in relieving the headache, changing the client's position is the priority to address the underlying cause. Resting in a dark room may be beneficial for headache relief but is not the priority intervention compared to adjusting the position to manage cerebrospinal fluid pressure.

Correct Answer: A

Rationale: To auscultate for a carotid bruit, the nurse should place the stethoscope at the base of the neck, near the carotid artery. A carotid bruit is an abnormal sound that indicates turbulent blood flow in the carotid artery, potentially due to arterial narrowing or atherosclerosis. Placing the stethoscope above the clavicle, over the sternum, or over the trachea would not provide the nurse with the optimal location to assess for carotid artery abnormalities.
