Nursing Elites

1. 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.

2. A client is receiving warfarin therapy. Which of the following findings should the nurse identify as an adverse effect of warfarin?

• A. Nausea
• B. Epistaxis
• C. Diarrhea
• D. Dyspepsia

Correct answer: B

Rationale: Epistaxis, or nosebleeds, can be an indication of excessive anticoagulation while on warfarin therapy. Warfarin is a blood thinner that helps prevent blood clots. Epistaxis can occur as a result of the blood-thinning effects of warfarin, leading to increased bleeding tendencies, including nosebleeds. Nausea, diarrhea, and dyspepsia are not typically associated with warfarin therapy; therefore, they are not the adverse effects the nurse should identify in a client receiving warfarin.

3. A healthcare professional is preparing to administer a dose of Hydromorphone IV to a client. Which of the following actions should the healthcare professional take?

• A. Administer the medication over 5 minutes.
• B. Administer a dose of Naloxone prior to giving the Hydromorphone.
• C. Assess the client's blood pressure prior to administration.
• D. Inject the medication into the client's subcutaneous tissue.

Correct answer: A

Rationale: The correct action for the healthcare professional preparing to administer IV Hydromorphone to a client is to administer the medication over 5 minutes. This slow administration is crucial to reduce the risk of hypotension and respiratory depression. Administering the medication rapidly can lead to adverse effects. Option B, administering Naloxone prior to Hydromorphone, is incorrect because Naloxone is used as an antidote for opioid overdose, not as a routine pre-medication. Option C, assessing the client's blood pressure before administration, is important but not the immediate action to take to reduce adverse effects of Hydromorphone. Option D, injecting the medication into the client's subcutaneous tissue, is incorrect as Hydromorphone is meant for intravenous administration for rapid onset of action.

4. A client presents in the Emergency Department with chest pain. Which of the following conditions is least likely to cause chest pain?

• A. Arthritis
• B. Peptic ulcer disease
• C. Myocardial infarction
• D. Gastric reflux

Correct answer: A

Rationale: Arthritis is a condition primarily affecting the joints and is not known to cause chest pain. Peptic ulcer disease, myocardial infarction, and gastric reflux are conditions that can present with chest pain due to various reasons such as inflammation, ischemia, or reflux of stomach acid into the esophagus, respectively.

5. A client is being discharged with a new prescription for Lisinopril. Which of the following instructions should be included by the healthcare provider?

• A. Avoid salt substitutes.
• B. Take this medication at bedtime.
• C. Increase your intake of potassium-rich foods.
• D. Take this medication with food.

Correct answer: A

Rationale: The correct answer is to instruct the client to avoid salt substitutes. Lisinopril, an ACE inhibitor, can lead to hyperkalemia, so it's essential to avoid salt substitutes that may contain potassium which can further elevate potassium levels. Choice B is incorrect because Lisinopril is typically taken once daily in the morning, not at bedtime. Choice C is incorrect as increasing potassium intake can exacerbate hyperkalemia when taking Lisinopril. Choice D is incorrect as Lisinopril is usually taken on an empty stomach, not with food.
