1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

2. The healthcare provider is preparing to administer a 1.2mL injection to a 4-year-old. Which is the best site to administer an IM injection?

• A. Vastus Lateralis
• B. Radial artery
• C. Dorsogluteal
• D. Rectus femoris

Correct answer: A

Rationale: The correct answer is A, Vastus Lateralis. The vastus lateralis site is recommended for IM injections in small children due to its large muscle mass, making it suitable for injections in pediatric patients. Choices B, C, and D are incorrect. The radial artery is not a site for IM injections; it is a site for arterial puncture. The dorsogluteal site is not recommended for children due to potential risks, such as injury to the sciatic nerve. The rectus femoris is not typically used for IM injections in children, as other sites like the vastus lateralis are more commonly preferred.

3. The nurse is caring for a client who underwent a total knee replacement yesterday. What activity level should the nurse encourage today?

• A. Bed rest with bathroom privileges only
• B. Frequent, short walks with assistance
• C. Range of motion exercises to the knee every four hours
• D. Leg elevation to reduce swelling

Correct answer: B

Rationale: After a total knee replacement, early ambulation is crucial for promoting circulation and preventing complications like thrombosis. Bed rest should be avoided as it can increase the risk of complications. Range of motion exercises are important but should be performed gradually and not excessively. Leg elevation is beneficial for reducing swelling but should not be the primary activity level encouraged immediately after surgery.

4. The nurse is providing discharge teaching to a client with newly diagnosed type 2 diabetes mellitus. Which instruction is most important to prevent complications?

• A. Monitor blood glucose levels regularly
• B. Maintain a low-fat diet
• C. Exercise regularly
• D. Take medication as prescribed

Correct answer: A

Rationale: Regular monitoring of blood glucose levels is crucial in managing diabetes and preventing complications. This allows the client and healthcare team to make timely adjustments to the treatment plan. While maintaining a low-fat diet, exercising regularly, and taking medication as prescribed are all important aspects of diabetes management, monitoring blood glucose levels takes precedence as it provides real-time information about the client's condition and helps prevent acute complications.

5. During a community health fair, a nurse is providing education on the effects of smoking. What is the most important information to include?

• A. Smoking can lead to cosmetic issues like tooth staining.
• B. Smoking is a leading cause of preventable death worldwide.
• C. Smoking temporarily elevates mood and alertness.
• D. Smoking is an expensive habit.

Correct answer: B

Rationale: The correct answer is B: 'Smoking is a leading cause of preventable death worldwide.' This information is crucial as it highlights the severe health risks associated with smoking, emphasizing the importance of cessation for overall health. Choice A is incorrect because cosmetic issues like tooth staining are not as significant as the life-threatening consequences of smoking. Choice C is incorrect because although smoking may temporarily elevate mood and alertness due to nicotine, this does not outweigh the serious health implications. Choice D is incorrect as while smoking is indeed an expensive habit, the focus should be on the health-related consequences to stress the urgency of quitting.
