1. The key to the prevention of a pandemic influenza is:

• A. Early detection
• B. Early antibiotic treatment
• C. Vaccination of at-risk populations
• D. Isolation of suspected cases

Correct answer: A

Rationale: The key to preventing a pandemic influenza is early detection. Detecting influenza cases early allows for timely public health responses to limit the spread of the virus. Early detection helps in implementing measures such as isolation, treatment, and vaccination to prevent the development of a full-blown pandemic. Antibiotics are not effective against influenza viruses, so early antibiotic treatment is not the key to prevention. While vaccination of at-risk populations is important in controlling the spread of influenza, early detection is crucial as it allows for timely implementation of vaccination strategies. Isolation of suspected cases is a containment measure rather than a prevention strategy; the key to prevention lies in early detection to stop the spread before it becomes a pandemic.

2. A client has volunteered to take part in a research study. After participating for two months, he decides that he can no longer tolerate the study and decides to leave. What are the client's rights in this situation?

• A. The client has a right to be released from the study but must reimburse the researchers for charges incurred
• B. The client has a right to be released from the study without any liability
• C. The client has a right to be released from the study but is prohibited from participating in any future studies
• D. The client does not have the right to be released from the study; he must finish his participation

Correct answer: B

Rationale: When a client voluntarily participates in a research study and later decides to withdraw, they have the right to be released from the study without any liability. It is unethical to force a participant to continue in a study against their will as this violates their autonomy and personal rights. Choice A is incorrect as it suggests that the client must reimburse the researchers for charges incurred, which is not typically the case unless agreed upon beforehand. Choice C is incorrect as there is no standard practice prohibiting a participant from future studies just because they withdrew from a current one. Choice D is incorrect because participants always have the right to withdraw from a research study at any time.

3. The healthcare professional needs to validate which of the following statements pertaining to an assigned client?

• A. The client has a hard, raised, red lesion on his right hand.
• B. A weight of 185 lbs. is recorded in the chart.
• C. The client reported an infected toe.
• D. The client's blood pressure is 124/70.

Correct answer: C

Rationale: Validation is the process of confirming that data are actual and factual. Data that can be measured can be accepted as factual, as in options 1, 3, and 4. The weight, blood pressure, and physical appearance of a lesion can be objectively verified. However, option C, the client reporting an infected toe, requires the nurse to directly assess the client's toe to confirm the statement. This choice involves subjective data that needs to be validated through direct observation, making it the correct answer. Options A, B, and D provide data that can be measured objectively and verified without the need for further assessment.

4. A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but the diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability.

• A. A lumbar puncture takes a sample of cerebrospinal fluid from the back, which will be analyzed by the lab.
• B. The physician will insert a needle at the level of L4-L5 in the spinal cord.
• C. The client should lie flat on their back for a specific period following the procedure.
• D. The risks of the procedure include headache, back pain, and infection.

Correct answer: B

Rationale: A lumbar puncture is performed to obtain cerebrospinal fluid for analysis to investigate various conditions affecting the client. During the procedure, the client is typically positioned on their side or sitting leaning over a table with their back rounded. The physician inserts a needle into the back around the L4-L5 vertebrae to collect the sample. Option A is incorrect because a lumbar puncture does not draw blood but instead collects cerebrospinal fluid. Option C is incorrect as the client should not necessarily lie flat for 24 hours post-procedure. Option D is incorrect as the common risks of a lumbar puncture include headache, back pain, and potential infection, not nausea, rash, or hypotension.

5. The nurse teaches a patient about the transmission of pulmonary tuberculosis (TB). Which statement, if made by the patient, indicates that teaching was effective?

• A. I will avoid being outdoors whenever possible.
• B. My husband will be sleeping in the guest bedroom.
• C. I will take the bus instead of driving to visit my friends.
• D. I will keep the windows closed at home to contain the germs.

Correct answer: B

Rationale: To prevent the transmission of pulmonary tuberculosis, it is important for the infected individual to minimize exposure to close contacts and household members. Sleeping alone in a separate room, like the guest bedroom, is an effective measure. The other choices are not ideal: Choice A is incorrect because spending time outdoors is encouraged for ventilation; Choice C is incorrect as using public transportation increases the risk of transmission; Choice D is incorrect because keeping windows closed limits ventilation, which is necessary to reduce the concentration of infectious particles in the air.
