Nursing Elites

1. Which of the following represents a normal serum potassium level?

• A. 1.5 mEq/L
• B. 3.0 mEq/L
• C. 4.0 mEq/L
• D. 6.0 mEq/L

Correct answer: C

Rationale: The correct answer is 4.0 mEq/L. Normal serum potassium levels typically range from 3.5-5.5 mEq/L. Choice A (1.5 mEq/L) is below the normal range, Choice B (3.0 mEq/L) is also below the normal range, and Choice D (6.0 mEq/L) is above the normal range. Therefore, the only option within the normal range is Choice C (4.0 mEq/L).

2. A test that can correctly identify those who do not have a given disease is:

• A. specific.
• B. sensitive.
• C. negative culture.
• D. marginal finding.

Correct answer: A

Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.

3. What information does the healthcare provider remember regarding do-not-resuscitate (DNR) orders in this scenario?

• A. That a DNR order may be written by a healthcare provider
• B. That everything possible must be done if the client stops breathing
• C. That medications only may be given to the client if the client stops breathing
• D. That life support measures will have to be implemented if the client stops breathing

Correct answer: A

Rationale: In a situation where a client has no family members and the client's wife is mentally incompetent, the healthcare provider may write a DNR order if it is deemed medically certain that resuscitation would be futile. A DNR order is a medical directive that instructs healthcare providers not to perform CPR if a patient's heart stops or if the patient stops breathing. Option A is correct because a DNR order can indeed be issued by a healthcare provider under certain circumstances, as it is a medical decision. Options B, C, and D are incorrect as they do not accurately reflect the concept of DNR orders and the decision-making process involved in such situations.

4. Which of the following statements is true about syphilis?

• A. The cause and mode of transmission are well understood.
• B. There is no known cure for the disease.
• C. When the primary lesion heals, the disease is cured.
• D. Syphilis can be cured with a course of antibiotic therapy.

Correct answer: D

Rationale: The correct statement about syphilis is that it can be cured with a course of antibiotic therapy. Syphilis is a treponemal disease that can be effectively treated with antibiotics, particularly long-acting penicillin G. The primary lesion of syphilis, known as a chancre, typically appears about three weeks after exposure and can involute even without specific treatment. If left untreated, secondary manifestations may occur, followed by latent periods. Specific treatment with antibiotics is crucial to prevent progression and transmission of the disease. Therefore, option D is correct. Option A is incorrect because the cause and mode of transmission of syphilis are well understood. Option B is incorrect as there is a known cure for syphilis. Option C is incorrect because the healing of the primary lesion does not indicate a cure for the disease.

5. What intervention should the nurse take for a client who has sustained a hyphema?

• A. Instruct the client to wear eye protectors in the future
• B. Keep the client at bed rest, typically with the head of the bed propped up
• C. Apply atropine eyedrops
• D. Apply an ice pack to the site of injury

Correct answer: B

Rationale: The correct intervention for a client who has sustained a hyphema is to keep them at bed rest, usually with the head of the bed raised. This positioning helps to reduce intraocular pressure and prevent further damage or rebleeding. Instructing the client to wear eye protectors in the future (Choice A) is not the immediate intervention required for a hyphema. Applying atropine eyedrops (Choice C) is not typically indicated for a hyphema. Applying an ice pack to the site of injury (Choice D) is not recommended for a hyphema as it can increase the risk of rebleeding. Therefore, the correct answer is to keep the client at bed rest.
