1. 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?

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.

2. A client has lost a significant amount of blood due to complications during surgery. What parameter does the nurse recognize as the earliest indication of new decreases in fluid volume?

Correct answer: A

Rationale: The earliest indication of new decreases in fluid volume is often recognized by an increase in pulse rate. Cardiac output is influenced by circulating blood volume, heart pumping action, and vascular tone. As fluid volume decreases, the body compensates by increasing the pulse rate. The formula for cardiac output is pulse rate multiplied by stroke volume. An elevated pulse rate helps maintain blood pressure with minor volume depletion. Pulmonary artery systolic pressure and pulmonary artery end-diastolic pressure, obtained through a pulmonary artery catheter, provide insights into pulmonary artery and left ventricle pressures at the end of diastole. These parameters are not the earliest indicators of new decreases in fluid volume compared to pulse rate.

3. What is the most common side effect of diuretics such as furosemide (Lasix)?

Correct answer: A

Rationale: The correct answer is 'Hypokalemia.' Diuretics like furosemide increase the excretion of potassium, leading to hypokalemia as a common side effect. Hyperkalemia (choice B) is the opposite condition characterized by high potassium levels, which is not typically associated with furosemide use. Hypernatremia (choice C) is increased sodium levels, while hyponatremia (choice D) is decreased sodium levels, neither of which are the most common side effects of furosemide. Therefore, choice A is the best answer.

4. A serum phenytoin determination is prescribed for a client with a seizure disorder who is taking phenytoin (Dilantin). Which result indicates that the prescribed dose of phenytoin is therapeutic?

Correct answer: C

Rationale: The correct answer is 16 mcg/mL (Choice C). The therapeutic serum phenytoin range is typically 10 to 20 mcg/mL. A level below this range may lead to continued seizure activity, indicating subtherapeutic levels. Choices A, B, and D are below the therapeutic range and would not be considered therapeutic for a client with a seizure disorder on phenytoin therapy.

5. A patient’s serum osmolality is 305 mOsm/kg. Which term describes this patient’s body fluid osmolality?

Correct answer: C

Rationale: The correct term to describe a patient with a serum osmolality of 305 mOsm/kg is 'hyperosmolar.' Normal osmolality ranges from 280 to 300 mOsm/kg. A patient with an osmolality above this range is considered hyperosmolar. Choice A ('Iso-osmolar') implies an equal osmolality, which is not the case in this scenario. Choice B ('Hypo-osmolar') suggests a lower osmolality, which is incorrect based on the provided serum osmolality value. Choice D ('Isotonic') refers to a solution having the same osmolality as another solution, not describing the specific scenario of this patient being above the normal range.
