1. Which system is primarily affected by tuberculosis (Mycobacterium)?

Correct answer: C

Rationale: Tuberculosis, caused by Mycobacterium tuberculosis, primarily affects the respiratory system. This aerobic bacillus thrives in highly oxygenated body sites, such as the lungs, growing ends of bones, and the brain. The bacillus is airborne, making the lungs a common site for infection. Choices A, B, and D are incorrect as tuberculosis predominantly impacts the respiratory system and rarely involves the stomach, heart, or skin.

2. In conducting a community health fair for a group of middle-aged citizens, which statement should the nurse emphasize in reducing the risk of coronary heart disease?

Correct answer: B

Rationale: Engaging in an aerobic exercise class every day is crucial in reducing the risk of coronary heart disease. Aerobic exercises help keep the heart in shape, lower blood pressure, and improve cholesterol levels. It is recommended to participate in at least 150 minutes of moderate-intensity aerobic exercise per week, which can be achieved by engaging in aerobic exercise daily. Choice A has been corrected to emphasize the frequency required to significantly reduce the risk of coronary heart disease. Choice C has been modified to suggest moderation in alcohol intake, as excessive alcohol consumption is harmful. Choice D is also incorrect as a balanced diet, not specifically high-protein, high-fat, is recommended to reduce the risk of coronary heart disease and maintain a healthy weight.

3. When assessing a client with early impairment of oxygen perfusion, such as a pulmonary embolus, the nurse should expect to find restlessness and which of the following symptoms?

Correct answer: C

Rationale: When a client has early impairment of oxygen perfusion, such as in a pulmonary embolus, the nurse should expect to find restlessness, diaphoresis, tachycardia, and cool skin. Tachycardia is a compensatory mechanism to increase oxygen delivery to tissues. Cool, clammy skin (choice A) is more indicative of impaired oxygen perfusion compared to warm, dry skin. Bradycardia (choice B) is less likely to occur in the early stages and is more common in severe cases. Eupnea (choice D) refers to normal respirations in rate and depth, which may not be altered in early impairment of oxygen perfusion.

4. The client is cared for by a nurse and calls for the nurse to come to the room, expressing feeling unwell. The client's vital signs are BP: 130/88, HR: 102, RR: 28. What should the nurse do next?

Correct answer: A

Rationale: Correct! The client's vital signs indicate tachycardia and tachypnea, which could be indicative of hypoxia. Administering a PRN anxiolytic would not address the underlying issue and could mask deterioration. Reassuring the client without further assessment or intervention could lead to a delay in appropriate care if there is a serious underlying cause for the symptoms. Determining the Glasgow Coma Scale is not relevant to the client's presenting symptoms of feeling unwell and suspecting something is wrong, coupled with abnormal vital signs.

5. A nurse is caring for her clients when her new admit arrives on the unit. What action by the nurse is most appropriate?

Correct answer: C

Rationale: The most appropriate action for the nurse in this situation is to ask the graduate nurse on the floor to initiate the assessment process until she can arrive. Nursing assistants are not qualified to perform assessments, and the unit secretary's role does not involve client assessments. Delegating the assessment to the graduate nurse ensures that a qualified healthcare professional is evaluating the new admission, aligning with the nurse's responsibilities and providing appropriate care.
