Nursing Elites

1. Which of the following is a local sign of infection?

• A. Swelling
• B. Rapid pulse
• C. Fever
• D. High white blood count

Correct answer: A

Rationale: A local sign of infection refers to symptoms that are specific to the area of infection. Swelling, heat, pain, and redness near the infected site are examples of local signs. In the context of infection, swelling occurs due to an accumulation of fluid and immune cells at the site of infection. Rapid pulse, fever, and high white blood count are more systemic responses to infection and not specific local signs. Rapid pulse can indicate systemic distress or sepsis, fever is a systemic response to infection, and high white blood count is a laboratory finding that suggests an immune response but is not a direct sign of infection at a specific site.

2. A client with asthma is being admitted for breathing difficulties. His arterial blood gas results are pH 7.26, PCO2 49, PaO2 90, and HCO3- 21. Which of the following best describes this condition?

• A. Uncompensated respiratory acidosis
• B. Compensated respiratory alkalosis
• C. Uncompensated metabolic acidosis
• D. Compensated metabolic alkalosis

Correct answer: A

Rationale: In this case, the client's arterial blood gas results show a pH of 7.26 and a PCO2 of 49, both of which are abnormal. A pH below the normal range of 7.35-7.45 indicates acidosis. The elevated PCO2 of 49 mmHg suggests respiratory acidosis as the primary issue. The normal range for PCO2 is 35-45 mmHg, so a value of 49 indicates the retention of excess CO2, leading to acidosis. The low HCO3- level of 21 also supports the presence of metabolic acidosis; however, the primary abnormality is respiratory, making this an uncompensated respiratory acidosis. Therefore, the correct answer is 'Uncompensated respiratory acidosis.' Choice B, 'Compensated respiratory alkalosis,' is incorrect because the client's pH is acidic, not alkalotic. Additionally, there is no compensation occurring for the primary respiratory acidosis indicated by the elevated PCO2. Choice C, 'Uncompensated metabolic acidosis,' is incorrect because while the HCO3- level is low, the primary issue indicated by the elevated PCO2 is respiratory acidosis. Choice D, 'Compensated metabolic alkalosis,' is incorrect since the arterial blood gas results do not support a metabolic alkalosis. The low HCO3- level would typically be seen in metabolic acidosis, but in this case, the primary issue is respiratory acidosis.

3. The client is receiving discharge teaching seven (7) days post myocardial infarction and inquires why he must wait six (6) weeks before engaging in sexual intercourse. What is the best response by the nurse to this question?

• A. "You need to regain your strength before attempting such exertion."?
• B. "When you can climb 2 flights of stairs without problems, it is generally safe."?
• C. "Have a glass of wine to relax you, then you can try to have sex."?
• D. "If you can maintain an active walking program, you will have less risk."?

Correct answer: B

Rationale: Following a myocardial infarction, there is a risk of cardiac rupture at the site of the infarction for approximately six (6) weeks until scar tissue forms. The advice to wait until the client can climb two flights of stairs without issues is common among healthcare providers as it indicates an adequate level of physical exertion tolerance and suggests a lower risk of complications during sexual activity. Choice A is not specific to the recovery timeline related to sexual activity post-myocardial infarction. Choice C is inappropriate as alcohol consumption should not be recommended before sexual activity. Choice D, though promoting an active lifestyle, does not directly address the safety concerns related to sexual intercourse post-myocardial infarction.

4. Sinusitis is caused by:

• A. Bacteria
• B. Fungus
• C. Virus
• D. Any of the above

Correct answer: D

Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.

5. A patient with peripheral vascular disease is receiving discharge instructions. Which of the following information should be included?

• A. Walk barefoot whenever possible.
• B. Use a heating pad to keep feet warm.
• C. Avoid crossing the legs.
• D. Use antibacterial ointment to treat skin lesions prone to infection.

Correct answer: C

Rationale: Patients with peripheral vascular disease should be advised to avoid crossing their legs as this can impede blood flow. Peripheral vascular disease, also known as arteriosclerosis obliterans, is primarily caused by atherosclerosis. Atherosclerosis results in the gradual progression of arterial occlusion due to the formation of atheromas. Crossed legs can further restrict blood flow, exacerbating the condition. Walking barefoot should be discouraged to prevent potential injuries to the feet. Using a heating pad can lead to burns and should be avoided to prevent thermal injuries. While using antibacterial ointment for skin lesions may be beneficial, it is not the priority instruction for patients with peripheral vascular disease.
