1. Which of the following lab values is associated with a decreased risk of cardiovascular disease?

• A. high HDL cholesterol
• B. low HDL cholesterol
• C. low total cholesterol
• D. low triglycerides

Correct answer: B

Rationale: High HDL cholesterol is associated with a decreased risk of cardiovascular disease because HDL cholesterol is known as 'good' cholesterol. It helps remove other forms of cholesterol, like LDL cholesterol, from the bloodstream, reducing the risk of plaque buildup in the arteries. Low HDL cholesterol (Choice B) is actually a risk factor for cardiovascular disease because it means there is less of the 'good' cholesterol to perform its protective functions. Low total cholesterol (Choice C) and low triglycerides (Choice D) are not necessarily associated with a decreased risk of cardiovascular disease, as the balance and types of cholesterol play a more crucial role in heart health.

2. 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.

3. For which condition might a client's antidiuretic hormone (ADH) level be increased?

• A. diabetes mellitus
• B. diabetes insipidus
• C. hypothyroidism
• D. hyperthyroidism

Correct answer: B

Rationale: The correct answer is diabetes insipidus. In this condition, the client's ADH level is increased. Diabetes insipidus is characterized by the inability of the kidneys to conserve water due to either inadequate secretion of ADH (central diabetes insipidus) or the kidneys' inability to respond to ADH (nephrogenic diabetes insipidus). Choices A, C, and D are incorrect. In diabetes mellitus, ADH levels are typically normal or elevated in response to high blood sugar levels. Hypothyroidism is not directly related to ADH secretion. In hyperthyroidism, ADH levels are usually normal or decreased.

4. 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.

5. Following abdominal surgery, a client has a nasogastric (NG) tube in place. What is the purpose of this tube immediately after surgery?

• A. simplify medication administration
• B. measure accurate input and output
• C. prevent accumulation of fluids and gas
• D. facilitate collection of specimens

Correct answer: C

Rationale: The correct answer is to prevent accumulation of fluids and gas. Immediately after abdominal surgery, the NG tube is used to keep the stomach decompressed, preventing the accumulation of fluids and gas. This helps in maintaining decompression to prevent surgical-site disruption and fluid loss through vomiting. Choices A, B, and D are incorrect because the primary purpose of the NG tube following abdominal surgery is to prevent complications related to fluid and gas build-up rather than simplifying medication administration, measuring input and output, or collecting specimens.
