1. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

Correct answer: B

Rationale:

2. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

Correct answer: B

Rationale:

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

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.

4. The term used to describe a blood sodium level of more than 145 mEq/L is:

Correct answer: C

Rationale: The correct answer is C: hypernatremia. Hypernatremia refers to an elevated level of sodium in the blood, specifically when it is more than 145 mEq/L. Choice A, hyponatremia, is incorrect as it refers to low sodium levels. Choice B, hyperkalemia, is incorrect as it refers to high potassium levels, not sodium. Choice D, hypercalcemia, is also incorrect as it relates to elevated calcium levels, not sodium.

5. When preparing a site for the insertion of an IV catheter, how should excess hair at the site be treated?

Correct answer: C

Rationale: The correct answer is to clip the hair in the area. Excess hair at the site of IV catheter insertion should be removed because it can be a potential source of infection. Clipping the hair is preferred over shaving because shaving can cause skin abrasions, increasing the risk of infection. Using depilatories is not recommended as they can irritate the skin, which is undesirable when preparing a clean site for an invasive procedure. Therefore, clipping the hair in the area is the most appropriate and safe method to prepare the site for IV catheter insertion.
