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

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. Prenatally malnourished babies frequently __________.

Correct answer: C

Rationale: Prenatally malnourished babies frequently catch respiratory illnesses. Malnourished babies have weakened immune systems, making them more susceptible to illnesses such as respiratory infections. This is a common consequence that is observed in babies who did not receive adequate nutrition during the prenatal period. Choices A, B, and D are incorrect. While malnourished babies may have feeding challenges, rejecting breast milk is not a common consequence. Enlarged hearts are not typically associated with prenatal malnutrition, and having a higher-than-average birth weight is unlikely in malnourished babies.

3. A nurse is preparing to administer an IV bolus of 0.9% sodium chloride to a client who is dehydrated. Which of the following actions should the nurse take?

Correct answer: B

Rationale: The correct action for the nurse to take is to assess the client's lung sounds before administering IV fluids. This is crucial to identify any signs of fluid overload, such as crackles or wheezes. Administering the solution slowly over 24 hours (choice A) is not appropriate for an IV bolus, which is a rapid infusion. Changing the IV tubing every 12 hours (choice C) is a standard practice for preventing infection but is not directly related to administering an IV bolus. Flushing the IV line with heparin every 4 hours (choice D) is a maintenance practice to prevent clot formation in the line, not specifically related to administering an IV bolus.

4. Stephen is a 62 y.o. patient that has had a liver biopsy. Which of the following groups of signs alert you to a possible pneumothorax?

Correct answer: A

Rationale: Dyspnea and reduced or absent breath sounds over the right lung are signs of a possible pneumothorax.

5. The nurse manager is talking with the CNA about her time management. Which of the following is an example of a nurse manager as a coach?

Correct answer: A

Rationale: The correct answer is A: 'Your timely response to patients' call lights is exemplary.' This choice reflects a positive reinforcement approach, providing feedback that praises and encourages good behavior. A coach in a professional setting aims to motivate, guide, and support staff rather than focusing on negative aspects or threats of discipline. Effective coaching involves recognizing and acknowledging employees' strengths and achievements to inspire continuous improvement and development. Choices B, C, and D are not examples of coaching as they either focus on criticism regarding appearance, use threatening language, or highlight a negative behavior without offering guidance or support.
