1. Which of the following is a characteristic symptom of multiple sclerosis (MS)?

• A. Muscle atrophy.
• B. Severe pain.
• C. Vision problems.
• D. Hearing loss.

Correct answer: C

Rationale: Vision problems are a characteristic symptom of multiple sclerosis (MS) due to demyelination of the optic nerve. This can lead to issues such as optic neuritis, blurred vision, double vision, or even total vision loss. Muscle atrophy (Choice A) is not a primary symptom of MS but can occur as a secondary effect of decreased mobility. Severe pain (Choice B) is not a typical symptom of MS, though some individuals may experience pain related to muscle spasms or other factors. Hearing loss (Choice D) is not commonly associated with MS unless there is an unrelated concurrent condition affecting the auditory system.

2. A client recovering from surgery has a large abdominal wound. Which of the following foods, high in vitamin C, should the nurse encourage the client to eat to promote wound healing?

• A. Steak
• B. Veal
• C. Cheese
• D. Oranges

Correct answer: D

Rationale: Oranges are a rich source of vitamin C, which is essential for wound healing due to its role in collagen synthesis. Citrus fruits like oranges, as well as other fruits and vegetables such as strawberries, kiwi, bell peppers, and broccoli, are high in vitamin C. Meats like steak and veal are not significant sources of vitamin C; they are primarily sources of protein. Cheese is not a good source of vitamin C but does provide calcium and protein.

3. The healthcare provider is caring for a patient who is receiving an intravenous antibiotic. The patient has a serum drug trough of 1.5 mcg/mL. The normal trough for this drug is 1.7 mcg/mL to 2.2 mcg/mL. What will the healthcare provider expect the patient to experience?

• A. Inadequate drug effects
• B. Increased risk of superinfection
• C. Minimal adverse effects
• D. Slowed onset of action

Correct answer: A

Rationale: A serum drug trough level below the normal range (1.7 mcg/mL to 2.2 mcg/mL) indicates that the medication concentration is insufficient to provide therapeutic effects, leading to inadequate drug effects. A low trough level does not directly correlate with an increased risk of superinfection, minimal adverse effects, or a slowed onset of action, as these are more related to the drug's concentration within the therapeutic range.

4. Which of the following lipid abnormalities is a risk factor for the development of atherosclerosis and peripheral vascular disease?

• A. Low concentration of triglycerides.
• B. High levels of high-density lipoprotein (HDL) cholesterol.
• C. High levels of low-density lipoprotein (LDL) cholesterol.
• D. Low levels of LDL cholesterol.

Correct answer: C

Rationale: The correct answer is C: High levels of low-density lipoprotein (LDL) cholesterol. High levels of LDL cholesterol contribute to the development of atherosclerosis and peripheral vascular disease by being deposited in the blood vessel walls, leading to the formation of plaques that can obstruct blood flow. Choice A is incorrect as a low concentration of triglycerides is not typically associated with an increased risk of atherosclerosis or PVD. Choice B is incorrect as high levels of high-density lipoprotein (HDL) cholesterol are actually considered protective against atherosclerosis as it helps remove cholesterol from arteries. Choice D is incorrect as low levels of LDL cholesterol are not typically considered a risk factor for atherosclerosis or PVD.

5. Oxygen via nasal cannula has been prescribed for a client with emphysema. The nurse checks the physician’s orders to ensure that the prescribed flow is not greater than:

• A. 1 L/min
• B. 3 L/min
• C. 4 L/min
• D. 6 L/min

Correct answer: B

Rationale: The correct answer is B, 3 L/min. Clients with emphysema typically receive oxygen at a flow rate of 1 to 2 L/min, with a maximum of 3 L/min. Higher flow rates can lead to oxygen toxicity in these clients, so it's crucial to adhere to the prescribed limits. Choice A (1 L/min) is too low and may not provide adequate oxygenation for the client. Choices C (4 L/min) and D (6 L/min) exceed the recommended flow rates for clients with emphysema and can increase the risk of oxygen toxicity.
