1. A female patient has been diagnosed with tuberculosis and begun multiple-drug therapy. The woman has asked the nurse why it is necessary for her to take several different drugs instead of one single drug. How should the nurse best respond to the patient's question?

A. “Multiple drugs are used because doctors need to combat the TB bacteria from different angles to effectively treat the infection.”
B. “The use of multiple drugs prevents the development of drug-resistant TB.”
C. “Multiple drugs are prescribed because the final testing results for TB can take up to 3 weeks to confirm the most effective treatment.”
D. “Multiple drugs are used in order to speed up the course of treatment.”

Correct answer: B

Rationale: The correct answer is B. Using multiple drugs in tuberculosis treatment helps prevent the development of drug-resistant TB. This approach is crucial because if the infection is not completely eradicated, the remaining bacteria may become resistant to the single drug used, making future treatments less effective. Choice A is incorrect because the use of multiple drugs is not due to uncertainty about which drug will work, but rather to address the bacteria from different angles. Choice C is incorrect as it misleads the patient about the reason for using multiple drugs. Choice D is also incorrect because the primary purpose of using multiple drugs is not to speed up treatment but to ensure effectiveness and prevent resistance.

2. During admission, 82-year-old Mr. Robeson is brought to the medical-surgical unit for diagnostic confirmation and management of probable delirium. Which statement by the client’s daughter best supports the diagnosis?

A. “Maybe it’s just caused by aging. This usually happens by age 82.”
B. “The changes in his behavior came on so quickly! I wasn’t sure what was happening.”
C. “Dad just didn’t seem to know what he was doing. He would forget what he had for breakfast.”
D. “Dad has always been so independent. He’s lived alone for years since mom died.”

Correct answer: B

Rationale: The correct answer is B because sudden onset of behavioral changes is a typical symptom of delirium. Delirium is characterized by an acute and fluctuating disturbance in attention, awareness, and cognition. Choice A is incorrect because delirium is not a normal part of aging. Choice C describes memory issues, which can be seen in delirium but are less specific than sudden behavioral changes. Choice D, while it mentions the patient's independence, does not directly support the diagnosis of delirium.

3. Which clients are at highest risk for pneumonia?

A. Those in their 20s and 30s and generally healthy
B. Those who exercise regularly and are not exposed to pathogens
C. Those who are hospitalized and immunocompromised
D. Those who have adequate respiratory function

Correct answer: C

Rationale: Clients who are hospitalized and immunocompromised are at the highest risk for pneumonia due to their weakened immune systems. Choice A is incorrect as young and healthy individuals typically have stronger immune systems. Choice B is incorrect because regular exercise can actually boost the immune system and reduce the risk of infections. Choice D is incorrect as having adequate respiratory function does not necessarily correlate with the risk of developing pneumonia.

4. Which manifestation of stress reflects the non-specific fight or flight response?

A. Decreased pupillary light response
B. Increased GI motility
C. Decreased short-term memory
D. Increased cardiopulmonary rates

Correct answer: D

Rationale: The correct answer is D, 'Increased cardiopulmonary rates.' The fight or flight response, activated by stress, is a non-specific physiological reaction that prepares the body to deal with perceived threats. In this response, the heart rate and breathing rate increase to supply more oxygen to muscles and vital organs, enabling a rapid response in dangerous situations. Choices A, B, and C are incorrect because decreased pupillary light response, increased GI motility, and decreased short-term memory are not typical manifestations of the fight or flight response.

5. Which of the following stores electrolytes and acts as an electrolyte pool?

A. Brain - Kidneys
B. Bone - Nails
C. Bone - Liver
D. Liver - Pancreas

Correct answer: B

Rationale: Bones store electrolytes and act as a reservoir, maintaining a balance of essential minerals like calcium and phosphate. The correct pair in this context is 'Bone - Nails.' Choices A, C, and D are incorrect because the brain, kidneys, liver, and pancreas perform other functions in the body and are not primarily responsible for storing electrolytes.
