1. A nurse is preparing to administer a tuberculosis (TB) test to a client. Which of the following is the correct method for administering this test?

Correct answer: A

Rationale: The correct method for administering a tuberculosis (TB) test is through an intradermal injection on the forearm. This technique allows for the proper administration of the test under the skin to assess the body's response to the TB antigen. Choices B, C, and D are incorrect because the TB test specifically requires an intradermal injection, not subcutaneous, intramuscular, or oral administration.

2. A client is admitted with the diagnosis of myocardial infarction (MI). Which of the following lab values would be consistent with this diagnosis?

Correct answer: D

Rationale: The correct answer is D: Elevated creatinine phosphokinase (CPK). Elevated CPK levels indicate muscle damage, including damage to the cardiac muscle, which aligns with the diagnosis of myocardial infarction. Choice A, low serum albumin, is not directly related to myocardial infarction. Choice B, high serum cholesterol, is more associated with conditions like atherosclerosis rather than acute myocardial infarction. Choice C, abnormally low white blood cell count, is typically not a lab value associated with myocardial infarction; instead, it could suggest other conditions like infections or bone marrow issues.

3. During the beginning shift assessment of a client with asthma who is receiving oxygen via nasal cannula at 2 liters per minute, the nurse would be most concerned about which unreported finding?

Correct answer: C

Rationale: Rapid, shallow respirations with intermittent wheezes are concerning as they indicate a potential worsening of the client's asthma. This finding suggests airway narrowing, which can lead to respiratory failure. Immediate intervention is required to address this respiratory distress. A pulse oximetry reading of 89% is low and indicates hypoxemia, but the respiratory pattern described in option C takes priority as it directly reflects the client's respiratory status. Crackles at the base of the lungs suggest fluid accumulation, which is important but not as immediately critical as the respiratory distress in asthma. Excessive thirst and a dry cracked tongue may indicate dehydration, which is relevant but not as urgent as the respiratory compromise presented in option C.

4. The nurse administers a booster dose of DTaP (diphtheria, tetanus, and pertussis) vaccine to an infant. Which level of prevention is the nurse implementing?

Correct answer: A

Rationale: The correct answer is A: Primary prevention. Administering a booster dose of DTaP vaccine to an infant is an example of primary prevention. Primary prevention aims to prevent disease or injury before it occurs by preventing exposure to risk factors. Tertiary prevention focuses on reducing the impact of a disease or injury that has already occurred, while secondary prevention involves early detection and treatment to prevent the progression of disease. Choice B, tertiary prevention, is incorrect as it deals with managing the consequences of a disease rather than preventing it. Choice C, secondary prevention, is also incorrect as it focuses on early detection and treatment rather than vaccination to prevent the disease. Choice D, primary nursing, is unrelated to the level of prevention being implemented in this scenario.

5. An example of the continuum health model of health and wellness would be:

Correct answer: B

Rationale: The continuum health model emphasizes ongoing health practices based on past behaviors. Choice A is incorrect as it describes a more binary approach to health. Choice C is incorrect as it focuses on alternative therapies rather than the continuity of health practices.
