Nursing Elites

1. All of the following are electrolytes except:

• A. chloride
• B. potassium
• C. sodium
• D. iron

Correct answer: D

Rationale: Iron is not an electrolyte; electrolytes like sodium, potassium, and chloride help maintain fluid balance and are critical for nerve and muscle function.

2. Which of the following terms describes the amount of blood ejected per heartbeat?

• A. Stroke volume
• B. Cardiac output
• C. Ejection fraction
• D. Afterload

Correct answer: A

Rationale: The correct answer is A: Stroke volume. Stroke volume refers to the amount of blood ejected by the left ventricle in one contraction. Choice B, Cardiac output, is the total volume of blood pumped by the heart per minute and is calculated by multiplying stroke volume by heart rate. Choice C, Ejection fraction, is the percentage of blood pumped out of the left ventricle with each heartbeat. Choice D, Afterload, refers to the pressure or resistance that the ventricles must overcome to eject blood during systole. Therefore, in the context of the question, the term that specifically describes the amount of blood ejected per heartbeat is stroke volume.

3. Loss of smell results in a condition that limits the capacity to detect the flavor of food and beverages, called:

• A. hypergeusia
• B. dysgeusia
• C. anosmia
• D. phantom taste

Correct answer: C

Rationale: The correct answer is C: anosmia. Anosmia refers to the loss of smell, which significantly affects the ability to detect flavors. Hypergeusia and dysgeusia, choices A and B, refer to heightened or distorted taste, respectively. 'Phantom taste' in choice D is not the correct term for the condition described in the question.

4. The client is discussing sources of carbohydrates with a nurse recently diagnosed with diabetes. Which food(s) identified by the client indicate understanding? (SATA)

• A. Starch
• B. Fiber
• C. Sugar
• D. All of the above

Correct answer: D

Rationale: The correct answer is D because starch, fiber, and sugar are all sources of carbohydrates. Starchy foods like bread, rice, and potatoes contain starch; fruits, vegetables, and whole grains provide fiber; and sugars are found in sweet foods like fruits, honey, and desserts. Fatty acids and amino acids are not sources of carbohydrates, so choices A, B, and C are correct while choices A and B are incorrect.

5. Which of the following is a good food source of iodine?

• A. Seafood
• B. Lettuce
• C. Broccoli
• D. Pork

Correct answer: A

Rationale: Seafood is a rich source of iodine, essential for maintaining healthy thyroid function and overall metabolic health. While lettuce, broccoli, and pork may contain some iodine, they do not provide as substantial an amount as seafood. Therefore, they are not considered 'good' sources of iodine in comparison.
