Correct Answer: A

Rationale: The correct answer is to mix the liquid iron preparation with antacids to reduce GI distress. This statement is incorrect because iron should not be mixed with antacids as it can significantly reduce the absorption of iron. Choice B is a good recommendation as taking iron with meals can help reduce gastrointestinal distress. Choice C is also correct as liquid forms of iron should be taken with a straw to prevent the discoloration of tooth enamel. Choice D is incorrect as iron preparations can be taken with juice or water, but not with milk, as calcium in milk can inhibit iron absorption.

Correct Answer: D

Rationale: A T4 cell count of less than 200 cells per deciliter indicates symptomatic AIDS. This severe depletion of T4 cells signifies advanced HIV infection and a significantly compromised immune system. Choices A, B, and C are incorrect because T4 cell counts above 2000, above 1000, or below 500 cells per deciliter, respectively, are not indicative of symptomatic AIDS.

Correct Answer: C

Rationale: The correct answer is C: yellow. Jaundice is a condition characterized by yellowing of the skin due to increased levels of bilirubin in the blood. This excess bilirubin causes the skin and whites of the eyes to appear yellow. Choice A, pale, is not typically associated with jaundice. Choice B, ruddy, describes a reddish skin color and is not indicative of jaundice. Choice D, pink, is a normal skin color and not a symptom of jaundice.

Correct Answer: A

Rationale: After a pneumonectomy, where a lung is surgically removed, there will be a decrease in breath sound volume on the affected side due to reduced airflow. This reduction in breath sound volume is expected as there is less lung tissue to produce sound. Choices B, C, and D are incorrect. Elevated tidal volume and respiratory capacity are not expected after a pneumonectomy, and wheezing is more commonly associated with conditions like asthma or bronchitis, not a recent pneumonectomy.

Correct Answer: A

Rationale: Pleurisy is an inflammation of the pleura and is often accompanied by an abrupt onset of pain. Symptoms of pleurisy include sudden sharp, stabbing pain that is usually unilateral and localized to a specific portion of the chest. The pain can be exacerbated by deep breathing. In contrast, pleural effusion is characterized by fluid accumulation in the pleural space, not sharp pain. Atelectasis involves collapse or closure of a lung leading to reduced gas exchange, but it does not typically present with sharp, stabbing pain. Tuberculosis is a bacterial infection that can affect the lungs but does not typically manifest with sudden sharp pain exacerbated by deep breathing.
