Nursing Elites

1. In a community health setting, which individual is at highest risk for contracting an HIV infection?

• A. 17-year-old who is sexually active with numerous partners
• B. 34-year-old homosexual in a monogamous relationship
• C. 30-year-old cocaine user who inhales and smokes drugs
• D. 45-year-old who has received two blood transfusions in the past 6 months

Correct answer: C

Rationale: The correct answer is C. Substance abuse, particularly using shared inhalation equipment like needles and pipes for drug inhalation, significantly increases the risk of contracting HIV. Choice A, the 17-year-old with multiple sexual partners, poses a risk of HIV transmission through sexual contact, but it is lower compared to the direct risk associated with sharing drug paraphernalia. Choice B, the 34-year-old homosexual in a monogamous relationship, is at lower risk since being in a monogamous relationship reduces exposure to HIV. Choice D, the 45-year-old who received blood transfusions, is also at lower risk as blood transfusions are now screened for HIV, decreasing the likelihood of transmission through this route.

2. A client reports feeling dizzy and light-headed when standing up. What is the nurse's best initial action?

• A. Instruct the client to sit or lie down
• B. Monitor blood pressure and pulse
• C. Administer an anti-dizziness medication
• D. Increase fluid intake

Correct answer: B

Rationale: The correct answer is B: Monitor blood pressure and pulse. When a client reports feeling dizzy and light-headed when standing up, the nurse's best initial action should be to monitor the client's blood pressure and pulse. These symptoms are indicative of orthostatic hypotension, which can be confirmed by changes in blood pressure and pulse when moving from lying to standing positions. Instructing the client to sit or lie down may provide temporary relief but does not address the underlying cause. Administering an anti-dizziness medication should not be the initial action without assessing vital signs first. Increasing fluid intake is important for overall health but is not the priority in this situation where vital sign monitoring is needed to assess for orthostatic hypotension.

3. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

4. A 4-year-old with acute lymphocytic leukemia (ALL) is receiving a chemotherapy protocol that includes methotrexate, an antimetabolite. Which information should the nurse provide the parents about caring for their child?

• A. Use sunblock or protective clothing when outdoors.
• B. Include the child in regular outings with the family.
• C. Obtain any childhood vaccinations that are not up-to-date.
• D. Use diluted commercial mouthwash for mouth care.

Correct answer: A

Rationale: The correct answer is to use sunblock or protective clothing when outdoors. Methotrexate can cause photosensitivity, making the child more prone to sunburns and skin damage. Therefore, advising the parents to protect their child's skin from direct sunlight exposure is crucial. Choice B is incorrect because exposing the child to direct sunlight without protection can worsen the photosensitivity caused by methotrexate. Choice C is incorrect as obtaining vaccinations is generally avoided during chemotherapy due to the child's compromised immune system. Choice D is incorrect as commercial mouthwash may contain alcohol, which can be irritating to the child's oral mucosa, especially during chemotherapy.

5. The nurse is caring for a client with Myasthenia Gravis. What time of day is best for the nurse to schedule physical exercises with the physical therapy department?

• A. Before bedtime, at 2000
• B. After breakfast
• C. Before the evening meal
• D. After lunch

Correct answer: B

Rationale: Scheduling physical exercises after breakfast is the optimal choice for a client with Myasthenia Gravis. This timing allows the client to benefit from renewed energy levels after overnight rest and intake of morning nourishment, enhancing the effectiveness of the therapy session. Choices A (Before bedtime, at 2000) is not suitable as energy levels are likely lower at night, affecting the client's ability to engage effectively in physical exercises. Choices C (Before the evening meal) and D (After lunch) may not be ideal as the client may experience fatigue or weakness later in the day, making it harder to participate actively in therapy.
