Nursing Elites

1. When reviewing facility policies for IV therapy with the team, a nurse manager should remind the team that which technique helps minimize the risk of catheter embolism?

• A. Performing hand hygiene before and after IV insertion
• B. Rotating IV sites at least every 72 hours
• C. Minimizing tourniquet time
• D. Avoiding reinserting the needle into an IV catheter

Correct answer: D

Rationale: Avoiding reinserting the needle into an IV catheter is crucial to minimizing the risk of catheter embolism. Reinserting the needle can lead to the severing of the catheter's end, potentially causing a catheter embolism, a serious complication. The other options, while important for IV therapy safety, are not directly related to preventing catheter embolism.

2. When teaching a client with a prescription for Phenytoin, which of the following instructions should the nurse include?

• A. Expect the development of a mild rash.
• B. Take the medication on an empty stomach.
• C. Monitor for signs of gingival hyperplasia.
• D. Increase your intake of calcium.

Correct answer: C

Rationale: Phenytoin is known to cause gingival hyperplasia, a condition characterized by overgrowth of gum tissue. The nurse should instruct the client to monitor for signs of gingival hyperplasia, such as swollen or bleeding gums. Good oral hygiene practices are essential to prevent or manage this side effect. Choices A, B, and D are incorrect. Phenytoin does not typically cause a mild rash, should be taken with food to reduce gastrointestinal upset, and does not warrant an increase in calcium intake.

3. What does it mean when a medication has a half-life?

• A. It only lasts for 30 minutes after the medication is given
• B. How long it takes for half of the dose to be eliminated from the bloodstream
• C. It is the peak of how effective the medicine is
• D. Drug is greatly reduced before it reaches the systemic circulation

Correct answer: B

Rationale: When a medication has a half-life, it refers to the time it takes for half of the dose to be eliminated from the bloodstream. This parameter is crucial in understanding the duration of action and dosing intervals for medications in clinical practice. Choice A is incorrect as the half-life is not about how long the medication lasts but about elimination from the body. Choice C is incorrect because the half-life is not about the peak effectiveness of the medicine. Choice D is incorrect as it does not accurately define the concept of half-life.

4. A client has a new prescription for Lisinopril. Which of the following adverse effects should the nurse monitor?

• A. Dry cough
• B. Weight gain
• C. Diarrhea
• D. Nausea

Correct answer: A

Rationale: The correct answer is 'A: Dry cough.' Lisinopril, an ACE inhibitor, commonly causes a persistent dry cough as an adverse effect. If the client experiences this side effect, it is important to notify the healthcare provider for assessment and possible medication adjustment.

5. What is the pharmacological action of metformin?

• A. Blocks stimulation of beta1 and beta2.
• B. Blocks vasoconstriction and aldosterone.
• C. Acts at many levels in the CNS to produce an anxiolytic effect.
• D. Decreases hepatic glucose production.

Correct answer: D

Rationale: The correct answer is D: Decreases hepatic glucose production. Metformin's primary pharmacological action is to decrease hepatic glucose production, leading to lower blood sugar levels and improved insulin sensitivity in the liver. Choices A, B, and C are incorrect because metformin does not block stimulation of beta1 and beta2 receptors, vasoconstriction, aldosterone, or act in the CNS to produce an anxiolytic effect. Therefore, these options are not reflective of metformin's mechanism of action.
