Nursing Elites

1. Extracellular fluid includes:

• A. plasma and intracellular fluid.
• B. interstitial and intracellular fluids.
• C. plasma and interstitial fluid.
• D. plasma, interstitial fluid, and intracellular fluid.

Correct answer: C

Rationale: The correct answer is C: 'plasma and interstitial fluid.' Extracellular fluid consists of all body fluids outside the cells, primarily including plasma (the liquid component of blood) and interstitial fluid (the fluid between cells). Choices A, B, and D are incorrect because intracellular fluid is located within the cells, not in the extracellular fluid compartment.

2. The patient asks the nurse if he will die if air bubbles get into the IV tubing. What is the nurse's best response?

• A. The system is closed, and that scenario is highly unlikely.
• B. Only relatively large volumes of air administered rapidly are dangerous.
• C. There is a risk of complications associated with IV administration.
• D. You have been influenced by movies too much.

Correct answer: B

Rationale: The correct answer is B because air emboli are more commonly associated with central vein access. Usually, only relatively large volumes of air administered rapidly are dangerous. It is a significant concern when air enters a central venous access line. Choice A is incorrect as it downplays the risk and is not entirely accurate. Choice C is too general and does not specifically address the patient's concern. Choice D is dismissive and does not provide any relevant information regarding the risk of air bubbles in IV tubing.

3. A patient with hypokalemia and heart failure is admitted to the telemetry unit. The nurse is aware that hypokalemia could cause which of the following abnormalities on an electrocardiogram (ECG)?

• A. Shortened P-R interval
• B. Inverted T wave
• C. Depressed U wave
• D. Elevated U wave

Correct answer: D

Rationale: The correct answer is D: Elevated U wave. Hypokalemia is associated with ECG changes such as an elevated U wave and flattened T waves. Choice A, a shortened P-R interval, is not typically seen in hypokalemia. Choice B, an inverted T wave, is more commonly associated with ischemia or CNS injury rather than hypokalemia. Choice C, a depressed U wave, is not a typical ECG abnormality seen in hypokalemia. Therefore, the correct ECG abnormality associated with hypokalemia is an elevated U wave.

4. When does dehydration begin to occur?

• A. the body reduces fluid output to zero.
• B. the body increases the release of ANH.
• C. the salivary secretions decrease.
• D. the salivary secretions increase.

Correct answer: C

Rationale: Dehydration leads to a decrease in the body's fluid levels, causing the salivary glands to produce less saliva, resulting in a dry mouth. Therefore, when dehydration begins to occur, salivary secretions decrease. Choice A is incorrect because the body does not reduce fluid output to zero during dehydration; it tries to conserve fluids. Choice B is incorrect as dehydration does not directly increase the release of ANH (Atrial Natriuretic Hormone). Choice D is incorrect because salivary secretions do not increase but decrease during dehydration.

5. A client at risk for mild hypernatremia is being taught by a nurse. Which statement should the nurse include in this client's teaching?

• A. Weigh yourself every morning and every night
• B. Check your radial pulse twice a day
• C. Read food labels to determine sodium content
• D. Bake or grill the meat rather than frying it

Correct answer: C

Rationale: The correct answer is to 'Read food labels to determine sodium content.' This is important for a client at risk for mild hypernatremia because monitoring sodium intake is crucial in managing this condition. Choice A is not directly related to managing hypernatremia. Choice B focuses on pulse monitoring, which is not specific to managing sodium levels. Choice D addresses cooking methods, which can be beneficial but is not as directly related to sodium intake monitoring as reading food labels.
