Nursing Elites

1. A nurse educator is reviewing peripheral IV insertion with a group of novice nurses. How should these nurses be encouraged to deal with excess hair at the intended site?

• A. Leave the hair intact
• B. Shave the area.
• C. Clip the hair in the area.
• D. Remove the hair with a depilatory.

Correct answer: C

Rationale:

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. The baroreceptors, located in the left atrium and in the carotid and aortic arches, respond to changes in the circulating blood volume and regulate sympathetic and parasympathetic neural activity as well as endocrine activities. Sympathetic stimulation constricts renal arterioles, causing what effect?

• A. Decrease in the release of aldosterone
• B. Increase of filtration in the Loop of Henle
• C. Decrease in the reabsorption of sodium
• D. Decrease in glomerular filtration

Correct answer: D

Rationale:

4. After teaching a client to increase dietary potassium intake, a nurse assesses the client's understanding. Which dietary meal selection indicates the client correctly understands the teaching?

• A. Toasted English muffin with butter and blueberry jam, and tea with sugar
• B. Two scrambled eggs, a slice of white toast, and a half cup of strawberries
• C. Sausage, one slice of whole wheat toast, half cup of raisins, and a glass of milk
• D. Bowl of oatmeal with brown sugar, a half cup of sliced peaches, and coffee

Correct answer: C

Rationale: Choice C is the correct answer as it includes foods high in potassium, such as raisins, whole wheat toast, and milk. Potassium is essential for various bodily functions, including maintaining proper heart and muscle function. Choices A, B, and D do not contain significant sources of potassium. Choice A consists mainly of carbohydrates and sugar, choice B focuses on protein and carbohydrates, and choice D provides carbohydrates and some fruit but lacks high-potassium options like in choice C.

5. Third spacing occurs when fluid moves out of the intravascular space but not into the intracellular space. Based on this fluid shift, the nurse will expect the patient to demonstrate:

• A. Hypertension
• B. Bradycardia
• C. Hypervolemia
• D. Hypovolemia

Correct answer: D

Rationale: In the scenario of third-spacing fluid shift, where fluid moves out of the intravascular space but not into the intracellular space, the patient is expected to demonstrate hypovolemia. Hypertension (Choice A) is unlikely as hypovolemia typically leads to decreased blood pressure. Bradycardia (Choice B) is not a common manifestation of hypovolemia, as the body often tries to compensate by increasing heart rate. Hypervolemia (Choice C) indicates an excess of fluid, which is the opposite of what occurs in third spacing.
